[0020] Example one
[0021] 1. Resin synthesis: Weigh 95kg of formaldehyde in the high-level metering tank and put it into the stainless steel reaction kettle, add sodium hydroxide solution to adjust the pH to between 8.5 and 9.5, then add 80kg of melamine while stirring and heat at the same time, when the temperature rises to 60℃ , Stop heating, wait for it to naturally rise to 80-85°C, keep it warm, and measure its water level (4°C). When the reaction is complete, add triethanolamine and cool.
[0022] 2. Mixing of raw materials: Cool the melamine formaldehyde resin to below 60℃ under stirring, add 26kg of glass fiber, 126kg of talc, 60g of benzoic acid, 300g of zinc stearate, 3.2kg of titanium dioxide, heating to keep the material temperature at 60℃ , Stir for 60 minutes.
[0023] 3. Drying of wet materials: open the condenser cooling water valve, open the vacuum pump, open the jacket steam valve, and slowly close the reactor vent valve. Under -0.05Mpa, when the material temperat...
