Problems solved by technology

[0007] However, none of the above-mentioned technologies has solved the problem of the canvas fabric being resistant to rainstorms and pockets of hot water. Therefore, it is of great practical significance to study a canvas fabric that is resistant to rainstorms and hot water as the tarpaulin base cloth.

Abstract

The invention discloses a rainstorm-proof and heat-resistant canvas fabric and a preparation method thereof. The preparation method comprises the following steps: (1) gray cloth cleaning treatment: washing the gray cloth in an aqueous solution of pretreatment agent a or pretreatment agent b, then rinsing and drying in clean water to obtain pretreated fabrics; (2) the Pretreatment fabric modification treatment: padding the pretreatment fabric with modifier c or modifier d, and then drying to obtain the fabric to be finished; (3) padding the fabric to be finished with waterproofing agent, crosslinking The resin, the catalyst and the penetrating agent are then baked to obtain the rainproof and heat-resistant canvas fabric. The invention enables the canvas fabric to have the common anti-drenching effect, and at the same time has anti-storm, water pressure resistance and good hot water performance.

Description

technical field [0001] The invention relates to a rainstorm-proof and heat-resistant canvas fabric and a preparation method thereof, belonging to the field of textile fabrics. Background technique [0002] The tarpaulin is a composite material made of bonding or compounding a layer of polymer coating glue or other materials on the fabric. As a common textile product for military, industrial and civilian use, tarpaulin has properties such as UV protection, water resistance, and aging resistance. It is an excellent textile fabric for protecting goods from external environmental influences. This composite material not only has the original performance and function of the fabric, but also increases the performance and function of the coating. [0003] Due to its strong and durable performance, traditional canvas is mostly used as the base fabric of freight tarpaulins for cars, trains, ships and various open warehouses. However, due to long-term exposure to the external environ...
