Abstract

The invention discloses a glass fiber enhanced hard polyvinyl chloride material and a preparation method. The material comprises PVC resin powder, glass firber, coupling agents, heat stabilizer, compatibilizer, lubricant, processing modifier, anti-impact modifier, filler and other components, and the weight proportion of the components is 100:1-50:0.1-10.0:0.5-3.0:0.5-5.0:0.2-5.0:0.1-5.0:0.1-10.0:1.0-10.0. Through the coupling compatibility and compatibilization-granulation technology, the preparation method ensures that the glass fiber and polyvinyl chloride resin are directly mixed, granulated, injection-molded and made into the glass fiber enhanced hard polyvinyl chloride material having higher water-pressure resistance, higher heat resistance and other advantages. The preparation method solves the problems that subsequent PVC composite material s are difficult to mix, process and blank in the prior high-speed mixing method, which is favorable for processing and molding the subsequent PVC composite materials.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced composite materials, and in particular relates to a glass fiber reinforced hard polyvinyl chloride material and a preparation method thereof. Background technique [0002] In recent years, the sharp rise in the prices of most domestic energy sources such as petroleum and iron ore and the increase in labor costs caused by the implementation of the new labor law have put enormous pressure on the cost of mid- and downstream industrial products. For the manufacturers of PVC injection molding products, although most of the domestic polyvinyl chloride (PVC) resin powders follow the coal carbide route and are not greatly affected by oil, the price of coal is also increasing day by day, and PVC resin powder is also available. However, the price of PVC injection molding products cannot be raised too high due to many factors in the customer market. This has caused many small PVC injection mo...
