Title: Water-proofing echo sounder receiver
Inventor: AIZAWA TETSUO
IPC: C08G18/69
Filed: 1992-11-19
Abstract: PURPOSE:To improve the water-proofing by covering a high polymer piezoelectric member being an acoustoelectric transducer with an urethane rubber cured at room temperature and covering it with an outer sheath rubber whose water-proofing is excellent so as not to deteriorate the high polymer piezoelectric member by heat. CONSTITUTION:A high polymer piezoelectric member 3 (PVDF or the like) is covered by a room temperature setting urethane rubber 2 cured at a low temperature by the injection molding method. The outside of the mold is covered with a rubber (EPT: ethylene-propylene terpolymer or the like) having an excellent water-proofing and they are heated and sulfated and the cured to form an outer sheath rubber 1. The high polymer piezoelectric member 3 is already covered by the room temperature setting urethane rubber 2 and since the urethane rubber 2 has a small head conductivity, the temperature rise in the high polymer piezoelectric member 3 is set to be lower than its deteriorated temperature by properly selecting the heat temperature and heat time at the heating and curing of the outer sheath rubber 1. Thus, even when the transducer is in use under water for a long period, the possibility of the deterioration in the electric insulation of the room temperature setting urethane rubber 2 is precluded.
