A composite canopy material with long-lasting antifouling film structure

Abstract

The invention relates to a long-lasting anti-fouling membranous-structure composite canopy material comprising a base membrane, base cloth and a surface membrane which are arranged sequentially from bottom to top, wherein a polyvinylidene fluoride coating is arranged on the surface membrane and is subjected to mirror face embossing treatment; the surface membrane as well as the base membrane is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride (PVC) resin powder, 50 to 70 parts of a dioctyl terephthalate plasticizer, 5 to 25 parts of calcium carbonate powder, 1 to 5 parts of a flame retardant, 1 to 4 parts of a smoke suppressant, 1 to 6 parts of a barium-zinc stabilizer and 1 to 5 parts of a titanium pigment; the base cloth is 1000D*1000D polyester fiber woven cloth. Raw materials such as PVC resin powder, the plasticizer, calcium carbonate, the stabilizer and the flame retardant are mixed, plasticizing and calendaring are carried out to obtain soft membranes, then the soft membranes are compounded with the 1000D*1000D polyester fiber woven cloth, and embossing is carried out after surface treatment of polyvinylidene fluoride, so that the long-lasting anti-fouling membranous-structure composite canopy material is a membranous-structure composite canopy material being long-lasting in fouling resistance, efficient in fire retardancy, and high in strength.

Description

technical field [0001] The invention relates to a canopy material, in particular to a composite canopy material with a long-lasting antifouling film structure. Background technique [0002] In recent years, the rapid development of new materials and production technology has improved the variety and quality of industrial textiles in my country. Canopy materials, as a traditional product in industrial textiles, serve all related fields of society and are a new economic growth of the textile industry. point. In the Wenchuan and Yushu earthquake relief, the canopy material played an important role, enhancing the influence of industrial textiles. played an important role in the capacity of natural disasters. [0003] Canopy materials are playing an increasingly important role in people's daily production and life. From storage cloth, to vehicle and boat cloth, to military camping, they all need to use canopy materials. However, the market for canopy materials currently on the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the canopy material on the market is generally made of two or three layers of PVC film sandwiching a layer of reinforcing material. Due to long-term use outdoors, the use environment is relatively harsh, and it must withstand ultraviolet rays and various atmospheric pollutants for a long time. On the one hand, it accelerates the degradation of PVC, on the other hand, due to the migration of plasticizer in PVC, the surface of the coating is sticky, which makes the product easy to stick to dust, crack, and the product fails prematurely
