Abstract

The invention relates to the technical field of glass fibers and in particular relates to alkali-resisting glass fiber cloth. The alkali-resisting glass fiber cloth comprises a glass fiber layer, a resin layer and a curing agent, and is characterized in that the corrosion-resisting resin layer covers the surface of the glass fiber layer; the mass part ratio of the glass fiber layer to the resin layer to the curing agent is 1: (3 to 5): (2 to 4). The alkali-resisting glass fiber cloth provided by the invention has excellent alkali resistance and high mechanical strength; the service life of a product is prolonged; a method is simple to operate and has small requirements on equipment, and the requirements of continuous industrial production can be met.

Description

(1) Technical field [0001] The invention relates to the technical field of glass fibers, in particular to an alkali-resistant glass fiber cloth. (2) Background technology [0002] Fiberglass mesh has the characteristics of high tensile strength, good cohesion, good positioning, and convenient use. It is currently widely used in wall reinforcement, external wall insulation, roof waterproofing, ground reinforcement, and lightweight building board reinforcement. It is an ideal inorganic non-metallic engineering material for the construction industry. However, it is extremely vulnerable to the erosion of alkaline media in concrete, resulting in a decrease in strength. [0003] At present, there are two main ways to improve the alkali resistance of glass fiber mesh: one is to use a special alkali-resistant glass fiber as the base material of the mesh, and the other is to use an alkali-resistant polymer coating to coat the mesh to prevent Its contact with the alkaline medium in ...
