Embodiment 1
[0039] A preparation method of an anti-deformation acrylic plate with thermal insulation function comprises the following steps:
[0040] S1. Preparation of acrylic base layer
[0041](1) Ultrasonic agitate methyl methacrylate, butyl acrylate, dipropylene adipate, and XT-2 rare earth stabilizer, mix them evenly, put them into a reaction kettle, heat up to 160°C, and form a glue; cool to Add benzoyl peroxide and stearic acid at 60°C, stir evenly and heat up to 280°C to obtain a reaction slurry;
[0042] In parts by weight, 80 parts of methyl methacrylate, 10 parts of butyl acrylate, 5 parts of dipropylene adipate, 5 parts of benzoyl peroxide, and 5 parts of stearic acid; XT- 2 Rare earth stabilizer is 1 part;
[0043] (2) Inject the reaction slurry into the mold, solidify at 60°C for 7 hours, then raise the temperature to 90°C and solidify for 40 minutes, cool to 18°C, and demould to obtain an acrylic blank;
[0044] (3) Polishing the surface of the acrylic blank described i...
