Example Embodiment

[0012] The present invention will be further described below in conjunction with the drawings.

[0013] figure 1 As shown, a PTFE glass fiber single-sided composite material includes a glass fiber substrate layer 1, a structural layer 2 and a polytetrafluoroethylene surface layer 3. The glass fiber substrate layer 1 is laminated with a structural layer 2 and a polytetrafluoroethylene surface layer 3 in turn. The glass fiber substrate 1 is a singeed and colored glass fiber cloth. The structural layer 2 is made of 93% PTFE emulsion , 6% hydrophilic nano silica, 2% polyacrylate acrylic organic thickener mixed and dip coated; the thickness of the glass fiber substrate layer is 0.25 mm-0.75 mm; the thickness of the structural layer is 0.05 mm-0.20 mm ; The thickness of the surface layer of PTFE is 0.01mm-0.05mm.

Abstract

The invention relates to a PTFE (Poly Tetra Fluoro Ethylene) glass fiber single-surface composite material. The composite material comprises a glass fiber base material layer which is covered with a structural layer and a PTFE surface layer in sequence; the structural layer is formed by mixing type dip-coating with 90%-95% of PTFE emulsion, 4%-9% of hydrophilic nanosilicon dioxide, and 1%-6% of crylic acid polyacrylate or 1%-6% of methacrylic acid homopolymer or 1%-6% of an organic thickener formed by the mixture of crylic acid polyacrylate and methacrylic acid homopolymer. The composite material with flexibility, toughness and folding endurance is convenient to use and easy to bend, and has the advantages of resisting to high temperature, corrosion, radiation and water, preserving heat, allowing repeated detachment and repeated use, needing no cleaning, being long in service life, and the like; the composite material can be widely used for protecting the outer layers of high- and low-temperature pipelines, pipe fittings, equipment insulating heat-preserving materials in the industries such as chemical industry, metallurgy industry, nuclear power industry and ship industry.

Description

technical field [0001] The invention relates to a glass fiber composite material, specifically a PTFE glass fiber single-sided composite material, and relates to the technical fields of special textiles, polymer materials and heat preservation. Background technique [0002] On pipes, pipe fittings, and equipment where hot and cold media flow, it is usually necessary to install insulation materials on the surface to effectively reduce heat loss. Traditionally used protective layers mainly include glass fiber reinforced plastics, plastics, aluminum alloy plates, stainless steel plates and other materials. Most of these materials need to be pre-customized according to pipes, pipe fittings and equipment. The manufacturing cost is high, transportation and installation are inconvenient, and their hardness is high. After installation and use, it is not conducive to disassembly and repeated use, and the plastic material has poor high temperature resistance, the metal material is ...
