Problems solved by technology

However, there are still many problems in the use of the existing cloth canopy, especially the used canopy cloth, there are many problems, such as easy water accumulation after rain, resulting in increased weight and affecting stability, such as poor light corrosion resistance, The lifespan is not long under the hot sun, etc., and because it is often attacked by rain, the rain tarpaulin is often prone to mildew and brittleness, and is easy to age

Abstract

The invention provides a waterproof and bacteriostatic canopy fabric and a processing method thereof. The canopy fabric consists of a warp-knitted fabric and a waterproof and bacteriostatic coating, wherein the waterproof and bacteriostatic coating is prepared from, by weight, 100 parts of PVC paste resin, 50-80 parts of environmentally friendly plasticizer, 15-20 parts of bamboo fibers, 0.5-2 parts of wasabi extract, 2-5 parts of stabilizer, 0-60 parts of packing, 0-20 parts of flame retardant, 0-5 parts of mildew preventive, 0-5 parts of antioxidant, 0-10 parts of adhesive and 40-70 parts of hydrophobic nano fibers. The added bamboo fibers are beneficial to increase of the strength and toughness of the canopy fabric, the wasabi extract and the bamboo fibers mainly play mildew-preventing and bacteriostatic functions through combined usage, and the waterproof and bacteriostatic properties of the canopy fabric are greatly improved by the waterproof and bacteriostatic coating.

Description

technical field [0001] The invention relates to the technical field of rain tarpaulins, in particular to a waterproof and antibacterial rain tarpaulin and a processing method thereof. Background technique [0002] The canopy is a kind of building assembly installed above the entrance and exit of a building or the balcony on the top to keep out rain, wind, and damage from falling objects. Although the cloth canopy that uses canopy cloth as the shelter material cannot prevent falling objects from falling in the same effect as the glass fiber reinforced plastic or membrane structure canopy, it is easy to fold due to its good shielding effect and can be used when not in use. The canopy can be put away in time when it is covered, it occupies a small space and is flexible to use. It has become the first choice of consumers, especially in the canopy used by street vendors and the canopy used by air conditioners. However, there are still many problems in the use of the existing clo...
