Example Embodiment
[0030] In the following embodiments, the raw materials are all common types purchased from the market, and there are no special restrictions. Example 1: Transparent composite polymer waterproof board, made of the following raw materials in parts by weight:
[0031]
[0032] The production process includes the following steps:
[0033] (1) Ingredients: Weigh the raw material components according to the formula;
[0034] (2) Mixing: Add the raw materials to a high-speed mixer, the temperature is 80°C, and the mixing time is 10-15 minutes;
[0035] (3) Blending and extrusion: single-screw extruder is used for blending and extrusion, and the temperature of the feeding section, melting section and metering section of the single screw are 120°C, 180°C, and 220°C respectively;
[0036] (4) Forming: The material is extruded and filtered through a screen-changing filter, and the melt metering pump is pressurized and pumped, and then it is formed into a sheet through a T-die, and then it is cale...
