Embodiment Construction

[0050] According to the accompanying drawings, the structure of the present invention is described in detail. A polyvinyl chloride waterproof engineering cloth proposed by the present invention immerses the base layer 1 in the polyvinyl chloride polymer coating to form uniform polyvinyl chloride on both sides of the woven base layer 1. Vinyl coating 2, into a prefabricated monolithic stock (e.g. figure 2 ), and then superimpose two single-piece materials on each other, and fuse them together under high temperature and pressure to become the final multi-composite engineering cloth (such as figure 1 ).

[0051] First of all, according to different use occasions, different braided layers with fibers or non-woven fabrics are selected as the base layer 1. Among them, the braided layers with fibers include glass fiber woven cloth, chemical fiber woven cloth, etc. According to different uses, examples focus on fire prevention, high Different tire base layers are selected for streng...

Abstract

A polyvinyl chloride waterproofing cloth is disclosed in the invention. It is made up of two or more single chips which include the base layer in the medium and the polyvinyl chloride covered in the both sides. The base layer is the fibrage cloth or the non-woven fabrics. The color of the two out polyvinyl chloride coats is different. The adjacent chips are pressed by the two press rolls to combine together. The physical property of the cloth has improved significantly because the polyvinyl chloride and the addition are used well.

Description

[0001] (1) Field [0002] The invention is a kind of building material used in the construction engineering industry, in particular to a kind of waterproof engineering cloth used to prevent leakage in places such as buildings and roads. (2) Background technology [0003] As known, there are waterproof and anti-leakage requirements in the following occasions. [0004] Environmental protection and greening places, such as landfills, harmful substances and sewage treatment plants, artificial lakes, ponds, roof greening, etc., need to prevent leakage and puncture of tree roots. [0005] In the field of industrial production, such as anti-seepage of oil storage tanks in the petrochemical industry, chemical reaction tanks, sedimentation tanks, coal washing tanks in mining, ash dumps, dissolution tanks, mine operation areas, epoxy resin floors, inorganic aggregate floors, metal aggregate floor. [0006] In the field of transportation, under the subgrade of subways, tunnels, roads a...
