Glass fiber reinforced polyvinyl chloride composite material production system and method

Abstract

The invention discloses a glass fiber reinforced polyvinyl chloride composite material production system and method, and belongs to the technical field of inorganic non-metallic materials. The glass fiber reinforced polyvinyl chloride composite material production system comprises a material mixing device, a heating device, a tank furnace wire drawing device, an infiltration wire collecting device and a composite material mixing and extruding device. Glass fiber raw materials are uniformly mixed through the material mixing device and are pneumatically conveyed to the tank furnace wire drawing device, the tank furnace wire drawing device is heated through the heating device, so that the raw materials are molten, then wire drawing forming is carried out to obtain glass fiber precursors, the surfaces of the glass fiber precursors are coated with an impregnating compound to obtain precursor cake, and the raw materials of the composite material are mixed and extruded by using a composite material mixing and extruding device to obtain the glass fiber reinforced composite material. The glass fiber production equipment is simple, the compatibility of the prepared glass fiber and resin is good, and the prepared glass fiber reinforced resin composite material has wider application under the general background of automobile lightweight.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a production system and method for glass fiber reinforced polyvinyl chloride composite materials. Background technique [0002] The Ministry of Industry and Information Technology requires that the fuel consumption target of 5L / 100km be achieved by 2020. However, in 2015, about a quarter of enterprises failed to meet the target of that year. At present, automobile manufacturers are under great pressure to save energy and reduce consumption, and automobile lightweight is an important way to achieve energy conservation and consumption reduction. [0003] The lightweight of automobiles is a concern of both consumers and car companies. In order to achieve the goal of lightweight, in addition to optimizing the structure and process design, the selection of materials is also very critical. In order to reduce the weight of cars, car companies use a large number...

AI Technical Summary

Problems solved by technology

However, the existing sizing agent has slow penetration on the surface of glass fiber and poor film-forming property, which leads to poor mechanical properties of the prepared composite material and is not convenient for application.

[0006] Polyvinyl chloride is one of the five general-purpose plastics. It is widely used, but its mechanical properties are poor. After compounding with glass fibers, due to the poor compatibility and poor adhesion between glass fibers and resin matrix, the prepared composite materials are poor. Mechanical properties need to be further improved
