## Title
Process for preparing a cement thread repairing composition

## Abstract

“PROCESS FOR OBTAINING CEMENT THREAD REPAIRER, CEMENT THREAD REPAIRER AND MANNER OF APPLICATION OF CEMENT THREAD REPAIRER”, particularly of a process a process for obtaining a colored liquid film used for aesthetic recovery of cement threads between ceramic parts and/or stones. It offers the advantages of being usable in packages of practical application, having high yield, and waterproofing the area that received the application.

## Background
This invention patent application concerns a new “PROCESS FOR OBTAINING CEMENT THREAD REPAIRER, CEMENT THREAD REPAIRER AND MANNER OF APPLICATION OF CEMENT THREAD REPAIRER”, particularly a process for obtaining a colored liquid film used to recover the original color or change the color of cement-based threads between ceramic and/or stone parts. The method of application includes a kind of squeeze tube with a foam tip specifically for applying the product on the placement joints.
Its advantages are, besides conferring a beautiful finish, the fact that it can be used in packages that allow its application with great ease; the possibility of choosing from a variety of more than 30 colors; and of waterproofing the area where the product was applied.
In the current STATE OF THE TECHNIQUE, there is no process or product for recovery or renewal of the aesthetic appearance of cement threads. The user must therefore remove the thread to make a new application, with the disadvantages of longer time required for this operation and the annoyance due to the messiness, increasing the cost-benefit ratio. Currently the thread is removed almost in a mechanical fashion, since there is no solution available in the market for renewal of the colors.
The invention is, specifically, a process a process for obtaining a colored liquid film used to recover the original color or change the color of cement-based threads between ceramic and/or stone parts.
The basic composition of the invention product is:


    
    
        Styrenated acrylic emulsion
        Inert minerals
        Inorganic pigments
        Alyphatic hydrocarbons
        Glycols
        Etoxylated and carboxylated tenso-active substances

The product's composition allows it to be washed in neutral soap and water, with the advantage of being usable in packages of practical application, and have a high application performance.

    
    





The invention will be explained more clearly through the drawings listed below:
FIG. 1: Drawing in perspective showing the invention product in its manner of application.



The “PROCESS FOR OBTAINING CEMENT THREAD REPAIRER, CEMENT THREAD REPAIRER AND MANNER OF APPLICATION OF CEMENT THREAD REPAIRER” is a process for obtaining a colored liquid film used for aesthetic recovery of cement threads between ceramic parts and/or stones, in internal as well as external areas. Due to the wide range of colors offered, the product allows recovery of the original color, or at least close to it, and the application of colors different from the original one, with the purpose of changing the decoration of the surroundings.
The components must be mixed in a rotating mixer with power adequate for the production. After the above equipment is turned on, the following raw materials must be added, respecting the limits of concentration:

    
    
        Drinking water (27%-32%)
        Ammoniac solution (0.05%-0.10%)
        Dispersant (0.28%-0.38%)
        Tripolyphosphate solution (0.30%-0.60%)
        Precipitated calcium carbonate (16%-18%)
        Calcium carbonate (16%-17.5%)
        Titanium dioxide (10%-20%)
    
    


The above components must be mixed at room temperature for approximately 40 minutes. The mixer is then turned off for the addition of one more components:

    
    
        Styrenated acrylic resin

After which the mixer is again turned on and the following raw materials are added:

        Coalescent (2% -4%)
        Fungicide (0.10%-0.20%)
        Bactericide (0.10%-0.20%)

The mixer should maintain the mixture at room temperature for approximately 10 minutes. Pigmentation will be carried out in a final stage, logically with the mixer operating to obtain a homogeneous distribution throughout the product.

    
    


The cement thread repairer, in its final state, is a liquid, colored product, specifically for aesthetic recovery of the threads, and may be used in colors close to those of the threads to be repaired or in different colors, to change the decoration of the surroundings.
The product's final composition includes styrenated acrylic emulsion, inert minerals, inorganic pigments, aliphatic hydrocarbons, glycols and etoxylated and carboxylated tenso-active substances.
In the method of application, the product, stored in a plastic squeeze tube (B), is applied directly on placement joints, between the parts, by squeezing the tube and sliding the foam (E) over the receiving surface.

## Claims

1. A process for preparing a cement thread repairing composition comprising:
combining within a rotating mixer: drinking water, ammoniac solution, dispersant, tripolyphosphate solution, precipitated calcium carbonate, calcium carbonate, and titanium dioxide to form a first solution;
