4.2 Process flow
The methyl methacrylate, stabilizer and pigment (red) were put in a gelatinization tank, and after stirring and dissolving, hydroxyethyl methacrylate, reinforcing monomer, and nitrile rubber that had been refined were placed in that order, and the rubber was placed at room temperature to make rubber. Swelling. Then, the hot water was heated in the jacket and stirred. The temperature in the kettle was kept at 55-70°C for 3-6 hours until the nitrile rubber was completely dissolved and the heating was stopped. Cool, add peroxide to stir evenly, and get A component. After the methyl methacrylate and the pigment (blue) were added into the gelatinization tank and stirred and dissolved, hydroxyethyl methacrylate, reinforcing monomer, and nitrile rubber that had been refined were put in order, and the rubber was swollen at room temperature to heat the mixture. Water heating into the jacket. Stir mash, put methacrylic acid and reducing agent at 50~60°C,
And heat and stir 6h, stop heating, then cool and add accelerator stirring hook, the material B component.
