Problems solved by technology

[0005] Although PVC / ABS blends are widely used in plastic molding processes such as injection, extrusion, and calendering due to their high impact strength, good thermal stability, flame retardancy, processing performance, and ideal cost performance, However, the existing PVC / ABS blend itself has defects such as "not too high bending strength, low heat distortion temperature, unsatisfactory appearance, and poor processing fluidity", which also limits its development and application. For example, the use of PVC / ABS blends There are no relevant reports on the technology of producing pipes from mixtures

Abstract

The invention discloses a PVC / ABS blend and a pipe thereof. The PVC / ABS blend consists of the following components in parts by weight: 100 parts of PVC resin, 20 to 80 parts of ABS granules, 1 to 3 parts of stability agent, 1 to 2 parts of lubricant, 0 to 5 parts of impact modifier, 0 to 10 parts of compatibility agent, 0 to 1 part of antioxidant, 0 to 1 part of ultraviolet absorber, 0 to 3 parts of flame retardant, and 1 to 3 parts of processing aid. Each component in the PVC / ABS blend is subjected to high-speed heating mixing and then cooled-mixed slowly, and finally the PVC / ABS pipe is obtained by granulation extrusion and forming. By optimizing and selecting the components and dosage required by the PVC / ABS blend, the PVC / ABS pipe which has the advantages of good impact resistance, good flame retardant and anti-aging property, and excellent mechanical property is prepared.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC / ABS blend and a pipe thereof. Background technique [0002] Polyvinyl chloride (PVC) has the advantages of good electrical insulation, good flame retardancy, flame retardant, wear resistance and chemical corrosion resistance, and is cheap. Its formula can be adjusted for different purposes to meet user requirements, so it is widely used , is currently one of the most widely used general-purpose materials. However, PVC also has problems such as low impact strength, poor processability, and insufficient heat resistance. [0003] ABS is a terpolymer of acrylonitrile, butadiene and styrene, A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. ABS resin has excellent processing performance and high impact strength, but it has disadvantages such as flammability and poor aging resistance. The most important thing is that ABS is relatively expen...
