Abstract

The invention discloses a manufacturing method of a flexible composite material. The manufacturing method comprises the steps of unwinding a base material film, respectively spraying a polyurethane adhesive solution on the front and back of the unwound base material film to form polyurethane adhesive layers, baking a solvent and then respectively carrying out hot pressing, rolling and winding on the adhesive layers and fiber papers, carrying out aftertreatment and slitting to obtain a finished product. By adopting the manufacturing method disclosed by the invention, the problem of apparent defects caused by the traditional manufacturing technique is solved, performance indexes of a produced product are up to the standard while appearance of the produced product is good, no scratch is produced, and export requirements are met.

Description

technical field [0001] The invention relates to a method for manufacturing a soft composite material, in particular to a method for manufacturing a coated composite soft composite material Background technique [0002] At present, the domestic market of flexible composite materials is highly competitive, and the industry's profit margins are low. Many insulating material companies are turning their attention to overseas markets, which have large market capacity and high profits. Foreign companies not only have strict requirements on performance indicators, but also have high requirements on product appearance. The amount of gluing and the uniformity of gluing are controlled by the steel wire scraper, and the performance indicators of the produced products can meet the standards, but there are generally defects in the appearance of poor gluing uniformity and obvious squeegee marks, which cannot meet the export requirements, resulting in failure to open overseas. market. ...
