Production technology of tank canopy fabric

Abstract

The invention provides a production technology of tank canopy fabric, by which the technical problems that no production technology is provided for conventional canopy fabric and the like are solved.The production technology comprises the following steps: a, selecting polyester yarn woven fabric with the stitch density of 1000D*1000D, which is sold in the market, as a base fabric layer; b, laminating the upper and lower sides of the base fabric layer with a PVC film and a PVDC film respectively by using an ordinary laminating machine; c, putting 75 parts of PVC paste resin, 25 parts of a plasticizer, 3 parts of a stabilizer, 14 parts of an antibacterial agent, 10 parts of an adhesive, 5 parts of an antiaging agent, 3 parts of an antioxidant, 0.5 part of an anti-UV agent and 18 parts of apigment into a reaction kettle; d, coating the surface of the PVC film with PVC coating liquid by using a coating device to form PVC coating; e, drying the PVC coating formed on the PVC film; f, coating the surface of the PVDC film with the PVC coating liquid by using the coating device to form PVC coating; g, drying the PVC coating formed on the PVDC film. The production technology has the advantage of high production efficiency.

Description

technical field [0001] The invention relates to a manufacturing process of a tank tarpaulin. Background technique [0002] The tarpaulin is a composite material made of a fabric covered with a polymer coating agent or other materials. This composite material not only has the original performance and function of the fabric, but also increases the performance and function of the coating. Due to the variety of base fabrics and coating materials to choose from, and the change of coating process, there are many varieties of tarpaulins, complete functions and wide application. PVC tarpaulin is made of coating PVC paste resin on the base fabric; compared with general PE tarpaulin, PVC tarpaulin is far superior to PP and PE tents in rain resistance, and is widely used in tents, cars, trains, warehouses, etc. and other fields have a wide range of uses. [0003] After searching, for example, Chinese patent literature discloses a high-strength PVC tarpaulin [application number: 2013...

AI Technical Summary

Problems solved by technology

[0004] Although the tarpaulin disclosed in this patent has stable mechanical properties, the tarpaulin has no anti-light and antibacterial functions, can only be used in a simple environment, and has a narrow range of use; and there is no manufacturing process, so the designed It is necessary to manufacture a tank tarpaulin
