Embodiment Construction

[0020] The technical characteristics of the present invention will be further elaborated below in conjunction with specific embodiments.

[0021] Weigh according to the content of the raw material components listed in Table 1, add it into the mixer, and transfer it to the cold roll when it is mixed to about 110 degrees.

[0022]

[0023]

[0024] Table 2 is the performance parameters of the pipe made of this injection molding material:

[0025]

[0026] Density is GB / T 1033-1986 Plastic Density and Relative Density Test Method. Tensile strength and tensile modulus of elasticity are determined by GB / T8804.2-2003 thermoplastic pipe tensile properties.

Abstract

The invention discloses a rigid polyvinyl chloride (PVC) injection molding material which is prepared from the following components in percentage by weight: 45-75% of 800-type resin, 5-15% of calcium carbonate, 1-3% of dioctyl ester, 2-5% of stabilizer, 1-5% of chlorinated polyethylene (CPE), 0.5-10% of industrial paraffin, 0.5-10% of titanium dioxide and 0.5-10% of plasticizer. The injection molding material prepared by the technical scheme disclosed by the invention has the advantages of good corrosion resistance, aging resistance and flame retardancy, higher mechanical strength and toughness, non-toxic or harmless materials used as raw materials, no generation of pollution and secondary pollution and broad application prospects, and can be widely used in transportation of hot water or tap water in daily life.

Description

technical field [0001] The invention discloses an injection molding material, specifically a rigid PVC injection molding material, and a preparation method of the rigid PVC injection molding material. Background technique [0002] PVC material is polyvinyl chloride, which is one of the plastic products with the largest output in the world. It is cheap and widely used. The polyvinyl chloride resin is white or light yellow powder. Different additives can be added according to different uses, and PVC plastics can exhibit different physical and mechanical properties. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products. The density of pure polyvinyl chloride is 1.4g / cm3, and the density of polyvinyl chloride plastic parts added with plasticizers and fillers is generally 1.15-2.00g / cm3. Rigid polyvinyl chloride has good tensile, bending, compression and impact resistance, and can be used alone as a str...
