Continuous production technology of fiber reinforced polyurethane foam plastic plate

Abstract

A continuous production technology of a fiber reinforced polyurethane foam plastic plate comprises the steps of continuous fiber arrangement, resin matrix material pouring, chopped fiber adding, uniform soaking of a reinforced material and a resin matrix material, foaming solidifying forming, and fix-length cutting. The continuous production technology belongs to the field of a composite plate ofglass fiber reinforced foaming resin, compared with a traditional bakelite floor and a bamboo floor, the fiber reinforced polyurethane foam plastic plate has the advantages of being environmentally friendly, stable in quality, excellent in performance, suitable for mass continuous production and the like, especially, a glass fiber reinforced polyurethane foam plate has the characteristics of the bakelite and bamboo floors and also has the better mechanical property and weather resistance than those of the bakelite and bamboo floors; and compared with a metal material floor, the fiber reinforced polyurethane foam plastic plate has the advantages of being light, high in strength, simple in structure, high in production efficiency and the like, and the problem that the loading capacity of a ship is reduced due to the fact that the bakelite and bamboo floors and the metal material floor cannot easily tie and fix cargoes and are large in self weight can be perfectly solved.

Description

technical field [0001] The invention relates to the field of composite material production, in particular to a continuous production process of fiber-reinforced polyurethane foam plastic plates. Background technique [0002] The container floor is an important part and main load-bearing accessory of the container. The traditional container floor is usually 28mm thick 19-layer plywood or plywood of other sizes and specifications, mainly made of dipterocarp from Indonesia, Malaysia and other real estates, such as abitong, clone and other tropical hard broad-leaved trees. However, with the sharp decline of hardwood resources and the backwardness of floor production technology, the development of the container floor industry has been severely restricted. With the development of the modern transportation industry, my country has become the largest producer of container flooring, but most of the raw materials for the production of container flooring come from imports, most of whi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a continuous production process for fiber-reinforced polyurethane foam plastic sheets, which has the advantages of environmental protection, stable quality, excellent performance, and is suitable for large-scale continuous production. The shortage of raw materials, quality decline, and lack of feasible alternative materials in Bakelite flooring restrict the development of the container flooring industry.
