Problems solved by technology

However, solvent-based acrylic pressure-sensitive adhesives cause serious environmental pollution and should be recycled; emulsion-type acrylic pressure-sensitive adhesives have poor water resistance, poor moisture resistance, and slow coating and drying speeds, that is, although acrylic pressure-sensitive adhesives can provide sufficient adhesion However, its temperature resistance is poor, the peeling force is too high and the range of peeling force is difficult to adjust flexibly, so there will be residual glue at high temperature, and it is difficult to peel off. In addition, the UV performance is poor and it is easy to age

Abstract

The invention provides a high-temperature resistant paper-based adhesive tape and a preparation technology thereof. The technology comprises the steps of firstly adding 20-100 parts of an organic silicone pressure-sensitive adhesive, not more than 80 parts of siloxane, 0.1-35 parts of polymethylhydrosiloxane, 0.02-1.0 part of alkynol or conjugated enyne to an agitated vessel, adding 0.8-4.0 parts of peroxide to 30-300 parts of a solvent until the peroxide is completely dissolved, standing for 5-10min, precipitating water and adding a supernate to the agitated vessel for stirring for 5-10min; adding 0.1-3.0 parts of platinum serial catalysts in the stirring process until stirring evenly to form glue; finally coating a paper base with the glue, drying in 80-100 DEG C for 60-120s and then raising the temperature to 150-180 DEG C and carrying out curing crosslinking reaction on the glue for 90-120s; and finally carrying out cooling and rolling. The high-temperature resistant paper-based adhesive tape has the characterstics of excellent high temperature and low temperature resistance and anti-ultraviolet performance, and the peel strength range can be flexibly adjusted.

Description

technical field [0001] The invention relates to the technical field of adhesives and adhesive products, in particular to a high-temperature-resistant paper-based adhesive tape and a preparation process thereof. Background technique [0002] With the gradual development of economy and science and technology, the demand for pressure-sensitive adhesives in industry, agriculture, transportation, medical care, national defense and civilian fields is increasing day by day, and the requirements are also getting higher and higher. The national 125 plan also clearly proposes to study high-performance, high-quality pressure-sensitive adhesives and products. [0003] The currently used pressure sensitive agents mainly include acrylic pressure sensitive agents and natural rubber pressure sensitive adhesives. Among them, although acrylic pressure-sensitive adhesives can be directly used for bonding some materials and objects, in most cases, the pressure-sensitive adhesives are applied t...
