Problems solved by technology

It is generally used in asphalt substrates or waterproof membranes for buried transportation pipelines with oil, natural gas, asphalt, etc. The organic fiber non-woven fabrics used are mainly polyester non-woven fabrics, but polyester non-woven fabrics Non-woven waterproof materials have many disadvantages, such as low porosity, high elasticity, low strength, high heat shrinkage, and not easy to be impregnated by asphalt.
In addition, the separate basalt fiber layer has defects such as poor protection, short service life, and weak adhesion

Abstract

The invention discloses a dustproof glass fiber composite felt. The dustproof glass fiber composite felt comprises a matrix layer and an outer surface layer, wherein the matrix layer is formed by alternately combining a carbon nanofiber layer and a glass fiber layer, the carbon nanofiber layer is composed of a single layer of carbon nanofiber felt, the outer surface layer comprises a basalt nonwoven fabric mat, a basalt gridding cloth, the basalt nonwoven fabric mat is adhered to the top of the basalt gridding cloth through an adhesive, the basalt nonwoven fabric mat is composed of basalt fiber and high elastic polyester silk, the basalt fiber occupies 48% to 53% of the total weight of the basalt nonwoven fabric mat, the high elastic polyester silk occupies 22% to 24% of the total weight of the basalt nonwoven fabric mat. The dustproof glass fiber composite felt provided by the invention has the advantages of being dustproof and waterproof, and extremely high in economic value and social benefit.

Description

technical field [0001] The invention relates to a dust-proof glass fiber composite felt. Background technique [0002] Basalt fiber is a continuous fiber drawn at high speed through a platinum-rhodium alloy drawing bushing after melting basalt rock at 1450°C to 1500°C. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of basalt rock materials composed of oxides such as silica, alumina, calcium oxide, iron oxide and titanium dioxide. After melting at high temperature, it passes through the bushing plate quickly. drawn. Basalt continuous fiber not only has good stability, but also has various excellent properties such as electrical insulation, corrosion resistance, combustion resistance, and high temperature resistance. In addition, the production process of basalt fiber produces less waste and less environmental pollution. After the product is discarded, it can be directly transferred to the ecological env...
