Problems solved by technology

However, after the tarpaulin strip made by this process is used outdoors for a period of time, since the back has not been treated, the moisture and impurities in the air will enter the base fabric and PVC coating along the yarn, causing mildew and further Causes a comprehensive reduction and loss of tarpaulin performance, seriously reducing the service life of the tarpaulin
At the same time, since the back of the membrane material has not been treated, the polyester yarn has not been "bundled" and fixed, and loose yarns and filaments will appear when the strip membrane material is cut, seriously affecting the appearance and operation

Abstract

The invention discloses a novel coating membrane material used for a tarpaulin clamping strip and a preparation method of the novel coating membrane material. The novel coating membrane material used for the tarpaulin clamping strip comprises a wicking-resistant base cloth layer, a first PVC coating, a second PVC coating, a third PVC coating and a polyurethane printing layer, wherein the front side of the wicking-resistant base cloth layer is coated with the first PVC coating, the back side of the wicking-resistant base cloth layer is coated with the second PVC coating, the surface of the first PVC coating is coated with the third PVC coating, and the surface of the second PVC coating is coated with the polyurethane printing layer; the wicking-resistant base cloth layer is made of wicking-resistant base cloth. According to the novel coating membrane material, the wicking-resistant base cloth is coated with the first PVC coating and the second PVC coating, so that the effect of fixing yarn to the clamping strip membrane material is achieved, the phenomena of yarn loosening and filament falling occurring in the processing process of the clamping strip membrane material are reduced, the operation speed is raised, and operation convenience is improved, The surface of one of the PVC coatings is coated with the polyurethane printing layer, so that waterproofness, the anti-mold property and wear resistance of the clamping strip membrane material are improved, and the service life of a tent is directly prolonged.

Description

technical field [0001] The invention relates to the technical field of new materials, and more specifically relates to a novel coating film material for tarpaulin strips and a preparation method thereof. Background technique [0002] Card strips are called hemming cloth in China and Keder abroad. In the processing and manufacturing of tarpaulins, clip strips are needed as accessories for linking and fixing with aluminum alloy pillars. According to statistics, in 2013, the domestic demand for PVC (polyvinyl chloride) coating film for card strips was about 300,000 m 2 , and increases with the increase of the tarpaulin. If foreign markets are considered, the estimated annual demand is about 1 million m 2 , The market potential is huge. [0003] At present, in China, the production technology and process of PVC coated film materials for card strips are relatively simple. After the high-strength low-shrinkage polyester woven base fabric is coated with two layers of PVC coati...
