Embodiment Construction
[0023]In parts by weight, mix 60-70 parts of polystyrene and 30-40 parts of vinyl acetate resin to obtain a mixed resin, pour the mixed resin into a three-necked flask containing 60-70 parts of styrene, and heat the three-necked flask Raise the temperature to 80-90°C, start the agitator, stir and disperse at a speed of 300-350r / min, keep warm and stir for 4-5 hours, discharge the material, naturally cool down to room temperature to obtain polyester glue, and set aside; Aluminum hydroxide powder Put it in a high-pressure airflow machine, and pulverize it by airflow for 10-15 minutes to obtain superfine aluminum hydroxide powder with a particle size of 50-80 μm. Pour 200-220 g of superfine aluminum hydroxide powder into In a beaker of sodium silicate solution, the mixed solution is obtained, and the mixed solution is placed in a high-speed disperser at a speed of 3000-3300r / min to disperse at a high speed to obtain a dispersion glue; in parts by weight, 20-25 parts of E-51 Epoxy...
