Example Embodiment

[0023] The present invention will now be further described with reference to the accompanying drawings

[0024] In the past, one of the processes for making duct tape was to cover the surface of the gauze with melted pure PE plastic particles; the current process is:

[0025] 1) PE plastic particles and fillers are mixed and melted at a high temperature of 250℃-270℃ in a weight ratio of 5:1; they are combined with gauze to form a plastic-coated single-sided cloth blank; and the following processes are combined to complete the manufacture of the product,

[0026] 2) Mix the non-silicon and solvent gasoline used for surface release treatment into the trough as needed, drive the rotation of the cloth blank through the anilox roller in the trough, and evenly smear the plastic-coated surface of the plastic-coated cloth blank. A layer of non-silicon is dried in a drying tunnel at 70-90°C, so that the non-silicon is stably solidified on the surface of the cloth blank;

[0027] 3) Pr...

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...
