       [0002]    This invention was not federally sponsored. 
       BACKGROUND OF THE INVENTION 
     Field of the Invention 
       [0003]    This invention relates to the general field of polyurethane elastic memory foam material, and more specifically toward a polyurethane elastic memory material that emits nano-negative ion far infrared rays and a method for preparing the same. A nano-negative ion far infrared ray emitting additive that belongs to the Lianfuya Established Series is added to polyester and/or polyether polyol to create a polyurethane elastic memory foam material that emits negative ions at a rate of 3,000 negative ions/cm 3  or more. The negative ions and far infrared rays provide for a positive effect in the treatment of many ailments. 
         [0004]    Due to the rapid development of the global economy, today&#39;s population encounters pollution that causes many ailments. Negative ions in the air can help counteract these negative effects and generally improve the health of a population. As early as the end of the 19 th  Century and the beginning of the 20 th  Century, scientists have found the existence of negative ions in the air and confirmed their significance in biology. In fact, nano-negative ion far infrared rays play a very important role in improving the living environment of people. For example, Pierce J. Howard, PhD, author of “The Owners Manual for the Brain: Everyday Applications from Mind Brain Research” and director of research at the Center for Applied Cognitive Sciences in Charlotte, N.C., proved that negative ions increase the flow of oxygen to the brain resulting in higher alertness, decreased drowsiness, and more mental energy. While the positive effects of negative ions are known, the materials and methods for efficient distribution of nano-negative ion far infrared rays to individuals are not well known. 
         [0005]    Thus there has existed a long-felt need for a material that is widely used in various aspects of life, such as furniture, clothing, vehicles, costumes, accessories, leisure produces, healthcare products, and toys for children, that are capable of effectively and efficiently emitting nano-negative ion far infrared rays. 
       SUMMARY OF THE INVENTION 
       [0006]    The current invention provides just such a solution by having a polyurethane elastic memory material that emits nano-negative ion far infrared rays and a method for preparing the same. A nano-negative ion far infrared ray emitting additive that belongs to the Lianfuya Established Series, also known as the Mason Established Series is added to polyester and/or polyether polyol to create a polyurethane elastic memory foam material that emits negative ions at a rate of 3,000 negative ions/cm 3  or more. The nano-negative ion far infrared ray emitting additive is a natural opal shale mineral material having nano-pores that is drilled from 200 meters underground. A powder is created from the material through the use of high pressures and temperatures along with destruction of the mineral. It is this powder that is the nano-negative ion far infrared ray emitting additive used to create the polyurethane elastic memory material that emits nano-negative ion far infrared rays. The negative ions and far infrared rays provide for a positive effect in the treatment of many ailments. 
         [0007]    Through our research, we have found that negative ions emitted from the product of “Lianfuya Established” series have a positive effect in the treatment of hypertension, asthma, influenza, arthritis, burns and the like. Further, the nano-negative ion far infrared rays emitted from the product of “Lianfuya Established” series is capable of preventing rachitis and scurvy, improving breathing by the lungs, assisting in metabolism, enhancing the body&#39;s natural immune system, assisting in deep sleep, reducing the frequency of turning over and waking up during sleep, alleviating body pain, shortening postoperative convalescence, remembering exterior structures of the human body, balancing different surface pressures of different individuals, absorbing kinetic energy and sound waves, adjusting function of the cerebral cortex, slowing sedimentation rate of the erythrocyte, and elongating blood coagulation time.

         [0013]    Polyester and/or polyether polyol (collectively “polymeric polyol”) combined with diisocyanate are common polymeric raw substances used to create polyurethane materials that are in conformity with international standards. These compounds can be either organic or inorganic. A particularly preferred embodiment includes between 50% and 70% polymeric polyol. 
         [0014]    The nano-far infrared negative ion additive belongs to the Lianfuya Established series. The Lianfuya Established series is characterized by a natural opal shale mineral material having non-pores. This mineral is capable of emitting 5,000 negative ions/cm 3  or more. However, when this mineral is combined together with the other substances listed in Table 1, the polyurethane elastic memory foam material emits 3,000 negative ions/cm 3  or more. A particularly preferred embodiment includes between 2% and 5% nano-far infrared negative ion additive. 
         [0015]    The adjuvant listed in Table 1 can be a softener, a colorant, a color fixative, a thickener, a humectant, an anti-scratching agent, a like substance, or any combination thereof. The foaming agent is preferably a physical or chemical foaming agent. The catalyst is preferably triethylene or diamine. The diisocyanate is an isocyanate that has two isocyanate groups. 
         [0016]    The method for making the polyurethane elastic memory foam material involves adding the nano-far infrared negative ion additive, the adjuvant, the mildew inhibitor, the flame retardent and the catalyst to the polyester and/or polyether polyol. This is then reacted with an isocyanate (diisocyanate) to form the polyurethane elastic memory material. A particularly preferred embodiment includes 25-30% diisocyanate. The resulting polyurethane elastic memory foam material emits nano-negative ion far infrared rays. 
         [0017]    In a particularly preferred embodiment, the substances listed in Table 2 are combined to create a polyurethane elastic memory foam material that emits nano-negative ion far infrared rays. The substances of Table 2 are combined and stirred for at least 45 seconds and no more than 90 seconds, and preferably about 60 seconds, and then formed into a mold. Using this preferred combination of substances using this method, it is possible to achieve 4,000 negative ions/cm 3  of polyurethane elastic memory foam material.

         [0018]    The polyurethane elastic memory foam material can be used in variety of applications. It can be used as a mattress, pillow, seat cushion, or other furniture application. Vehicle or aircraft seats can comprise this material to provide comfort and beneficial nano-negative ion far infrared rays to the user. Uses can also include clothing, accessories, leisure produces, health care products such as hospital beds, and toys and other products for children, such as rocking horses and car seats. 
         [0019]    In another preferred embodiment, a user puts 400 g of polyether polyol, preferably polyether glycol, and 187 g of diisocyanate in a room with constant temperature which is 20 degrees Celsius. The mixture is then allowed sufficient time to adjust to 20 degrees Celsius. Then the polyether polyol is put it into a mixing container. The mixer of the mixing container is started thereby stirring the mixture after pouring 10 g of adjuvant, 9.5 g of foaming agent, 2.5 g of catalyst, 1.5 g of mildew inhibitor, and 40 g of flame retardant into the mixing container. After stirring for 3 to 5 minutes, negative ion additive and far infrared additive in the amount of 25 g is added in to the mixture and stirring continues for 5 to 10 minutes. Then, polyether polyol, preferably polyether glycol, is poured into the mixing container and stirring continues for 3 seconds. The resulting mixture is then put into a prepared mold that renders foaming polymerization immediately. After the polymerization, it goes to a post curing process. The whole polymerization process takes about 3 minutes. The post curing time is around 2 hours, during which the temperature of the foam itself is increased to about 150 degrees Celsius. Then the well-formed foam body will be sent to a cutting process, and modified into varieties of finished product as required.
