Preparation process of flame-retardant hand-tearing cloth adhesive tape

Abstract

The invention discloses a preparation process of a flame-retardant hand-tearing cloth adhesive tape, which comprises the following steps of placing a melamine solution in a water tank at the front side of a first drying oven, enabling fiber cloth to pass through the water tank at the front side and then enter the first drying oven for drying, and placing a polytetrafluoroethylene solution in a water tank at the front side of a second drying oven, enabling the fiber cloth dried out of the first drying oven to penetrate through a water tank on the front side of a second drying oven and then enter the second drying oven to be dried, coating the fiber cloth subjected to the previous treatment in a coating machine, specifically, coating a layer of acrylic acid sensitive glue on the fiber cloth, adding antimony trioxide and aluminum hydroxide into the acrylic acid sensitive glue, and uniformly stirring, enabling the coated fiber cloth to enter a main drying oven to be dried, dividing the main drying oven into a plurality of sections, and enabling the temperatures of the sections to be sequentially increased and then decreased in the advancing direction of the fiber cloth, and laminating and rolling the dried fiber cloth. The process can solve the problem that drippings can be generated when an existing cloth adhesive tape is burnt.

Description

technical field [0001] The invention relates to the field of cloth tapes, in particular to a preparation process of flame-retardant hand-teared cloth tapes. Background technique [0002] General electronic and electrical products on the market need to use tapes with external insulation properties, but ordinary tape products are difficult to achieve insulation properties. Acetate cloth tape is to uniformly coat the prepared acrylic adhesive on the surface of acetate fiber cloth substrate, and form a viscous polymer material after high temperature reaction. Due to the strong moisture absorption and breathability of the acetate fiber cloth base material, good resilience, easy to wash and dry, no static electricity and pilling, and excellent aging resistance, which can last for more than 15 years, so that the acetate cloth tape has high temperature resistance and aging resistance. , soft, good formability, easy to unwind, acid, alkali, mildew resistance and other properties, it...
