Abstract

The invention belongs to the technical field of polymer composite materials and in particular relates to a polyvinyl chloride composite material and a preparation method thereof. The invention aims to solve the technical problem of providing a cold-resistant, heat-resistant and high-impact polyvinyl chloride composite material. The polyvinyl chloride composite material comprises 80-145 parts of polyvinyl chloride and 20-35 parts of thermoplastic polyurethane elastomer rubbers by weight. By adopting the thermoplastic polyurethane elastomer rubbers to modify polyvinyl chloride, the polyvinyl chloride composite material expands the applicable temperature range of the polyvinyl chloride materials, ensures the product to have strength, rigidity and toughness, has good cold resistance and heat resistance and is suitable for manufacturing pipes or profiles.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a polyvinyl chloride composite material and a preparation method thereof. Background technique [0002] Polyvinyl chloride is a general-purpose plastic with low price, corrosion resistance and low energy consumption, which is widely used. However, its hard products have poor impact resistance and are prone to brittle cracks. At the same time, the plasticizer is easy to migrate, which reduces the material performance; moreover, PVC has disadvantages such as poor thermal stability, low cold resistance, low elasticity, and low comprehensive strength. limit its scope of application. [0003] Patent application number [201010191968.9] mentions a cold-resistant polyvinyl chloride plastic and its preparation method. The invention proposes to add cold-resistant plasticizers dioctyl sebacate (DOS) and dioctyl adipate (DOA) method to improve the cold resis...
