Abstract

The invention relates to a manufacturing process for a hot-melt textured adhesive tape. The process comprises the following steps: by utilizing baking soda water as a medium, controlling space humidity through a humidity controller, allowing the adhesive-coating surface of textured paper to form a layer of a baking soda water contained thin film, then uniformly coating an adhesive on the surface of the textured paper containing the baking soda water contained thin film, decomposing the baking soda water into water and carbon dioxide under heating through a heating device, subjecting an adhesive layer to expansion at high temperature, and allowing carbon dioxide and vapor to penetrate through the adhesive layer and evaporate so as to obtain a porous foam-like adhesive layer. The manufacturing process provided by the invention improves thickness and initial adhesion of a hot-melt adhesive, reduces production cost, and does not cause environmental pollution.

Description

technical field [0001] The invention relates to a manufacturing process of a hot-melt masking tape, in particular to a manufacturing process of a hot-melt masking tape that utilizes products after thermal decomposition of baking soda water to make the adhesive layer form a foam-like structure. Background technique [0002] Masking paper is a high-tech decoration and spraying paper (also known as color-separation tape paper because of its special properties), which is widely used in interior decoration, spraying of household appliances and spraying of high-end luxury cars. Masking tape is a roll-shaped adhesive tape made of masking paper and pressure-sensitive glue as the main raw materials. The pressure-sensitive adhesive is coated on the masking paper, and the other side is coated with anti-sticking material. It is mainly used for coating masking of decoration, painting, baking varnish, etc., and semiconductor component fixing and other industries. Due to the particularity...
