[0027] SDS (Baling Petrochemical Co., Ltd., graft rate 3.0%, grafted polar monomers are 2-vinylpyridine, 4-vinylpyridine and its isomer mixture) and chlorinated Polyethylene CPE (domestic) is uniformly mixed in a weight ratio of 38:62 to make a composite compatible phase.
[0028] Heat up PVC resin (Beijing Huaer Group, grade SG-5, type five, degree of polymerization 800), calcium zinc stabilizer (Dalian Kaimisen Company), and lubricant (domestic) to 100°C under high-speed stirring, and put Put it into the cold mix and cool to room temperature, and stir evenly with ABS resin (Taiwan Chimei Company, brand 777) and composite compatibilizer. The specific composition is shown in Table 1 based on 100 parts by weight of polyvinyl chloride resin. A two-roll mill is used for mixing, and the mixing temperature is 180-200°C. Tablets are pressed on a flat vulcanizer at a temperature of 190-210°C. The test specimens were processed by a milling machine and tested for various mechanical ...
