Problems solved by technology

[0003] A Chinese utility model patent for a high-strength tarpaulin (authorized notification number CN206812558U) discloses a high-strength tarpaulin, which includes a waterproof layer, a heat-insulating layer, a flame-retardant layer, a base cloth layer and a wear-resistant layer, and adopts a composite multi-layer The method solves the problems of heat insulation, flame retardant and wear resistance, and then it can be understood that the production of high-strength tarpaulin is only to add reinforcement layer, stainless steel fiber layer or mixed weaving reinforcement wire in the core layer on this basis. The tarpaulin has the following problems: First, the materials of each layer are different, so their properties are also different. The overall performance of the composite material is unstable. It is inevitable that some composite layers will be damaged before other layers. For example, the waterproof layer does not have high strength, flame retardancy, and Wear and other characteristics, the waterproof layer will wear out before other layers; secondly, the multi-layer tarpaulin is compounded, its thickness will continue to increase, and its weight will continue to increase, especially for high-strength tarpaulins containing stainless steel fibers, the increase in weight will lead to use inconvenient

Abstract

The invention discloses a high-strength paulin and a manufacturing method thereof and belongs to the technical field of paulins. The manufacturing method of the high-strength paulin comprises the following specific steps of substrate fiber preparation, surface treatment, sol preparation, wetting, base cloth manufacturing, aging treatment, supercritical drying, surface layer raw material preparation, surface layer raw material treatment and curtain coating so as to obtain the high-strength paulin. By treating the surface of a substrate fiber, the surface roughness is improved, a novel substratefiber material is adopted for base cloth manufacturing, by adopting a technology of compounding first and weaving afterwards, surface layer coating is conducted, through the surface layer, the waterproof performance, heat insulation performance and ageing-resistant performance of the paulin are improved, and the prepared paulin is low in weight, long in service life and low in application cost.

Description

technical field [0001] The invention relates to the technical field of tarpaulins, in particular to a high-strength tarpaulin and a manufacturing method thereof. Background technique [0002] Cloth is a waterproof material with high strength, good toughness and softness. It is often used as canvas, polyester with polyurethane coating or made into polyethylene plastic. Existing tarpaulins are usually divided into two categories: coarse tarpaulin and fine tarpaulin. The general process of tarpaulin production is to select ordinary materials such as polyester as warp and weft yarns, and coat a layer of waterproof material on the surface to make them. For the production of tarpaulins with special requirements, different composite layers are generally added on the existing basis by means of multi-layer composite, such as: wear-resistant layer, flame-retardant layer, etc. [0003] A Chinese utility model patent for a high-strength tarpaulin (authorized notification number CN20681...
