Problems solved by technology

[0002] At present, most of the mesh fabrics on the market are produced by scraping or laminating alone. The products produced by these two production processes currently have certain defects. The physical performance indicators such as resilience are good, but the products produced by this process have poor airtightness, high formula cost, and difficult control of production process conditions
The cost of the product produced by laminating process is lower, and the appearance and variety are easy to replace, but its physical performance indicators such as peel strength and tear strength are not as good as those produced by coating and scraping.

Abstract

The invention provides a clad net cloth gluing and surface processing technology. A preparation of the clad net cloth comprises the steps of: previously impregnating polyester fiber net cloth by means of PU glue or PVC glue with a coating impregnating machine; laminating and gluing the double faces of the polyester fiber net cloth with a PVC thin film under high temperature by a gluing machine; and surface processing with surface processing agent after cooling and shaping. The technology combines the impregnating with a coating machine, the laminating and the gluing with the gluing machine, with the subsequent surface processing with the surface processing machine of the clad net cloth; is scientific and reasonable; can produce a product with good physical indexes such as peel strength and tear strength, and the like, as well as good air tightness; can greatly improve the surface self-cleaning and pollution-resistant performance, and the surface abrasion resistance and tear resistance; can prevent from photooxidation aging; can prolong the service life; and has low cost, good competitiveness and obvious economic benefit.

Description

technical field [0001] The invention belongs to the field of chemical materials, and more specifically relates to a bonding and surface treatment process of a sandwich cloth. Background technique [0002] At present, most of the sandwich fabrics on the market are produced by scraping or laminating alone. The products produced by these two production processes currently have certain defects. Physical performance indicators such as resilience are good, but the products produced by this process have poor airtightness, high formula cost, and difficult control of production process conditions. The cost of the products produced by the bonding process is low, and the appearance and variety are easy to replace, but its physical performance indicators such as peel strength and tear strength are not as good as those produced by coating and scratching. Contents of the invention [0003] The purpose of the present invention is to provide a bonding and surface treatment process for th...
