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

The invention is a building material used in the construction engineering industry, in particular to a waterproof engineering cloth used to prevent leakage in buildings, roads and other places. The single-piece material is composed of the base layer (1) in the middle and the PVC coating (2) on both sides, and two or more single-piece materials are fused together to form the base layer (1) and PVC coating (2). Vinyl-coated (2) interspaced multi-layer composite engineered cloth. The base layer (1) is made of fiber woven or non-woven fabric. The polyvinyl chloride coatings (2) of the two outermost layers have different colors. Two adjacent single-sheet materials are superimposed on each other, the superimposed surface is heated, and then squeezed by two rolling rollers (3) to form fusion. The present invention heats and applies heat and pressure during the merging process of single-piece materials, and the polyvinyl chloride in the middle layer is specially protected, so that the additives including plasticizers and the characteristics of polyvinyl chloride can be fully exerted and maintained in a state of being isolated from the outside world, and the physical Performance has been tested to be significantly improved.

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...
