Process for making hot-melt pressure sensitive adhesive type fabric base adhesive tape

Abstract

The manufacturing engineering for melten pressure-sensitive adhesive cloth-based belt belongs to manufacturing technique sphere of gel products. The method is characterized in that mixing and melting the PE plastic particles and filling materials; scoring with the gauze to produce plastic-coated cloth embryo; evenly daubing a non-silicon on the plastic-coated face of the plastic-coated cloth embryo; mixing and stirring thermoplastic elastomer, resin, naphthenic oil and modifying agent to prepare melten pressure-sensitive belt; inflowing into the gelholder filled with nitrogen; evenly covering the gel on the gaze cloth of the silicon-coated cloth embryo. The invention adds partial regenerative cotton into the pure polyester to obtain the product, which is of more adequate raw materials compared with pure polyester gauze and of moderate price, at the same time, adding mineral filler into PE largely reduces the cost of manufacture, and is of good suppleness, can not easily cock and can fast seal; the melten pressure-sensitive gel adopted by new cloth-based (pipe) gel is pure solid glue and is hard to burn, the industrial process can not produce any gaseous effluent and can not produce damage to people and environment, which belongs to a safety and environment-friendly type glue.

Description

technical field [0001] The invention belongs to the technical field of adhesive product manufacture, specifically the technical field of production, use and manufacture of tape-shaped adhesive products. Background technique [0002] The cloth base tape currently available on the market, also known as duct tape, is made of pure high-pressure PE plastic particles melted at high temperature and combined with pure polyester gauze to form a plastic-coated cloth embryo. , and then apply glue to the other side to become a semi-finished product of cloth base (pipe) tape; because polyester gauze is a product extracted from petroleum and other chemical raw materials, its production cost is high, due to the shortage of resources such as crude oil and international political factors. Affected by the impact, the price of oil is constantly increasing, resulting in a serious shortage of production resources for pure polyester gauze, and the price continues to rise. Pure high-pressure PE (...

AI Technical Summary

Problems solved by technology

[0003] a. Most of the solvent volatilizes (90%) during the glue coating process, causing a lot of waste of resources;

[0004] b. During the solvent volatilization process, the production site has a strong odor and serious environmental pollution;

[0005] c. Because of its low solid content and serious environmental pollution, the requirements for production facilities are high, the investment is large, and the cost is high
