Problems solved by technology

[0005] Although glass fiber and spunlace non-woven fabrics are relatively mature in construction, they are rarely used in construction skins at present, and even if they are used, they have defects such as density and insufficient hardness due to their relatively simple raw materials.

Abstract

The invention discloses a glass fiber compound surface skin which is prepared from glass fabric, spunlace nonwoven fabric, polypropylene randon copolymer and a binding agent. The binding agent is prepared from liquid resin, quartz sand, dicyandiamide, dimethyl formamide, polyacrylic ester, dipropylene glycol monomethyl ether, dimethicone, fumaric acid, fumaric acid anhydride, trimesic acid, trimesic acid anhydride and a negative ion surface active agent. The invention further discloses a production method of the glass fiber compound surface skin. The method includes the following steps of preparing the raw materials, preparing solidification liquid, conducting rolling and thermocuring, conducting quick cooling to form a semi-solidified plate, cutting the semi-solidified plate, and conducting natural cooling to the normal temperature to obtain the glass fiber compound surface skin. The glass fabric and the spunlace nonwoven fabric are used as base materials, polypropylene random copolymer and the binding agent are added, and the produced glass fiber compound surface skin has excellent performance on the aspects of appearance, high compactness, high strength, abrasion resistance, high temperature resistance, corrosion resistance, acid and base resistance and low expansion.

Description

technical field [0001] The invention relates to a building dough and a production method, in particular to a glass fiber composite dough and a production method. Background technique [0002] The building skin is a kind of surface building material pasted on the surface of the concrete structure. Its purpose is to make the concrete surface more beautiful, and it can also bear part of the external load acting on it. [0003] Traditional building skins are mostly made of wood skins, plastic skins, metal skins or composite skins made of these skins. Although they play a corresponding role in aesthetics and load-bearing, traditional skins are wear-resistant, high-temperature resistant, corrosion-resistant, The acid and alkali resistance and low expansion performance are poor, resulting in the single function of the dough and the defects that it is easy to be old and damaged in the later stage. [0004] Glass fiber (original name in English: glassfiber or fiberglass) is an inorg...
