Abstract

The invention provides a basalt fiber reinforced polyvinyl chloride composite material. The basalt fiber reinforced polyvinyl chloride composite material comprises the following components in parts byweight: 30-38 parts of basalt fibers, 55-65 parts of polyvinyl chloride, 0.3-0.8 part of a coupling agent, 0.1-0.3 part of a cross-linking agent, 0.1-1.0 part of an assistant cross-linking agent, 0.2-1.0 part of a coupling agent and 0-8 parts of titanium dioxide. According to the basalt fiber reinforced polyvinyl chloride composite material provided by the invention, the wear resistance is improved.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride materials, in particular to a basalt fiber reinforced polyvinyl chloride composite material. Background technique [0002] Polyvinyl chloride can be made by substitution reaction of ethylene, chlorine and catalyst. Due to its fire resistance and heat resistance, polyvinyl chloride is widely used in various products in various industries, but at the same time, polyvinyl chloride also has many shortcomings: poor resistance to abrasive wear and fatigue wear, and poor compressive strength and hardness . [0003] Basalt fiber is a high-tech product that can compete with glass fiber and carbon fiber. It is made of natural basalt ore as raw material, which is melted at high temperature, clarified and homogenized, and then drawn into fibers after melting. During the manufacturing process of basalt fibers, there is no emission pollution of metal oxides. After recycling, they can be naturally d...
