Embodiment 1～3

[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 ...

Abstract

The invention provides a resin composition, which contains the following constituents in part by weight: 100 parts of polrvinyl chloride resin, 3 to 50 parts of ABS resin and 3 to 30 parts of composite compatilizer which are blended, wherein the composite compatilizer consists of a thermoplastic elastomer graft and chlorinated polyethylene; the thermoplastic elastomer graft is the graft of styrene-butadiene-styrene block copolymer or styrene-pentadiene-styrene block copolymer and a polar monomer; and the mass ratio of the thermoplastic elastomer graft to the chlorinated polyethylene in the composite compatilizer is 10:90 to 60:40. The resin composition has extremely high shock resistance, excellent low temperature resistance, superior stretching resistance, good rigidity and good thermodynamic property. A method for preparing the composition of the invention is simple in process and easy in operation.

Description

technical field [0001] The invention relates to a resin composition and a preparation method thereof. Specifically, it relates to a polyvinyl chloride / acrylonitrile-butadiene-styrene copolymer alloy resin composition and a preparation method thereof. technical background [0002] PVC resin is a thermoplastic high polymer polymerized from vinyl chloride monomer. It is an amorphous polymer and contains microcrystals with a crystallinity of 5-10%. The outstanding advantage of PVC is that it is flame retardant, has excellent wear resistance, chemical corrosion resistance, and low leakage of gas and water vapor. In addition, the comprehensive mechanical properties, product transparency, electrical insulation, heat insulation, noise reduction, and vibration reduction are also good, and it is a general-purpose material with the most superior performance-price ratio. Its disadvantages are poor thermal stability, tensile properties, and impact resistance. The notched impact streng...
