| titleOfInvention | Manufacture method of acrylic plate |
| abstract | The present invention relates to a method for producing an acrylic plate, the use of a water tank and a steam bath as a polymerization means for heat treatment in the conventional acrylic plate manufacturing method, the size of the facility is large, the facility cost is consumed, maintenance and management There was a problem that it was not easy, the defect rate was severe, and the strength and other physical properties were not good.n n n Therefore, the present invention synthesizes the MMA and the catalyst of the acrylic plate made of a syrup (S) having a certain viscosity and then injected into the cell cast plate 30 and sealed in the heat treatment in the polymerization tank (P), The cell cast plate 30 containing the syrup (S) was put in the water tank 10 and heat-treated at a temperature of 50 ° C. to 60 ° C. for 3 to 4 hours, and then 4 to 5 hours at a temperature of 65 ° C. to 75 ° C. After the heat treatment during the high temperature heat treatment for about 2 hours at a temperature of 110 ℃ to 120 ℃ by using the infrared light generated by the infrared device 210, the size of the equipment is smaller than in the prior art can reduce the cost of the equipment It is easy to maintain and manage, and also to minimize the bad elements of the acrylic plate by the heat treatment of the medium temperature and the high temperature using infrared light, and to improve the strength and other physical properties better. |
