Embodiment Construction

[0013] A kind of preparation method of novel non-woven composite chopped strand mat, carries out according to the following steps:

[0014] a) Production of non-woven composite materials

[0015] The polyvinyl chloride emulsion emulsified by the OP-1 emulsifier is used, and 0.5% of the total weight of polyvinyl alcohol and acrylic acid mixed thickener are added for mixing and stirring to prepare a high-viscosity viscous emulsion. Then apply the scraping technology, so that the thermoplastic emulsion is uniformly scraped on the surface of the non-woven material and the decorative paper material, and then dried and rolled to form a composite non-woven material and decorative paper material. Among them, the thickness of emulsion scrape coating is 3 or 5 or 7 or 8g / m 2 ;

[0016] Technical indicators of thermoplastic emulsion: solid content: ≥36%; PVC content: ≥97%; use viscosity: 3000-5000mpaS; emulsion secondary melting point: 100-180℃.

[0017] b) Powder chopped strand mat ...

Abstract

The invention relates to a method for preparing a novel non-woven composite chopped strand mat, which comprises the steps of: producing a non-woven composite material, producing a powder chopped strand mat and compositing the non-woven composite material with the chopped strand mat, wherein the first step comprises the procedures of uniformly coating high-viscosity thermoplastic emulsion on the surface of the non-woven material, and then drying and rolling; the second step comprises the procedures of chopping, forming, dusting and drying glass fiber; and the third step comprises the procedures of thermally pressing and compositing the non-woven composite material at a drying channel outlet of the chopped strand mat, controlling the hot-pressing temperature to be 120-180 DEG C and the thermally-pressing speed to be 3-5kgf / cm<2>, keeping thermal pressing for 5-10s, rapidly cooling, rolling and forming. The chopped strand mat prepared by using the method has smooth surface, tight gluing, does not generate arch cambers and wrinkles and shrinkage, is good in uniformity, and can directly enter a workshop for being thermally pressed on the roof, thus the working efficiency is improved and the cost is saved. Meanwhile, because multiple procedures of resin pasting and the like are reduced, the utilization rate is greatly improved and the secondary pollution is reduced.

Description

technical field [0001] The present invention relates to a preparation method of glass fiber chopped strand mat composite material. Background technique [0002] As a new type of reinforcing material, glass fiber chopped strand mat is widely used in plastic products and FRP products of different processes: such as car roof trims, insulating materials for transformers, sanitary ware, chemical anti-corrosion pipelines, storage tanks, ships, Seats, building components and more. At present, the formation of car roof accessories is as follows: after purchasing the chopped strand mat, the automobile manufacturer coats the chopped strand mat with resin, and then pastes the non-woven fabric and other materials for surface decoration. However, this method not only wastes working time but also wastes materials; moreover, the sticking effect is very poor, and it is extremely prone to uneven sticking and waste of edges; fall off, causing environmental pollution.
