Problems solved by technology

[0002] Canvas plays an important role in people's daily production and life. From storage cloth, to vehicle and boat cloth, to military camping, tarpaulin is needed. However, most of the tarpaulin products on the market currently have fractures and tears. Low strength, poor fireproof performance, insufficient softness, poor self-cleaning performance and other shortcomings, customers expect new products with high strength, good flame retardancy, high breaking and tearing strength, and surface self-cleaning function

Abstract

The present invention discloses a manufacturing method of tarpaulin with high strength and direct coating knife scraping, and the method is performed as per the following steps: (1)a composition with a certain weight including PVC paste resin, plasticizer, stabilizer, filling, fire resistant agent and painting is mixed to form coating agent; (2)the mixed coating agent is grinded and filtrated; (3)1-5kg cross-linking agent is added into each 100kg coating agent, and are evenly coated on a base cloth, and drying is executed; (4)after plasticizing and forming, surface treatment agent is used for treating. The tarpaulin manufactured with the method in the present invention has the advantages of waterproof, oil resistance, dirt resistance, fireproof, aging resistance, stripping resistance, etc., which can be used for carriage tarpaulin, carriage side curtain cloth and cloth for a container with the top opened; train tarpaulin and ship tarpaulin; building material, applied for building material for soft roof, such as a supermarket, a stadium and a sightseeing building; for military use, for temporary rest of the field army, headquarters during wartime, etc.

Description

technical field [0001] The invention belongs to the technical field of textile materials, in particular to a method for manufacturing tarpaulins by direct coating method. Background technique [0002] Canvas plays an important role in people's daily production and life. From storage cloth, to vehicle and boat cloth, to military camping, tarpaulin is needed. However, most of the tarpaulin products on the market currently have fractures and tears. Due to the shortcomings of low strength, poor fire performance, insufficient softness, and poor self-cleaning performance, customers expect new products with high strength, good flame retardancy, high breaking and tearing strength, and surface self-cleaning functions. Therefore, the old products urgently need to be upgraded to meet the requirements of customers, and are applied to new and expanding application fields such as soft cars, soft roofs and military equipment. Contents of the invention [0003] In order to make up for ma...
