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 adhesive tape and a preparation process thereof. The preparation process includes adding 20-100 parts of organosilicon pressure-sensitive adhesive and not more than 80 parts of siloxane into a stirring vessel; adding 1.2-4.0 parts of peroxide initiator into 30-300 parts of solvent until a peroxide dissolves completely, standing for 5-10 minutes, adding supernatant into the stirring vessel after moisture precipitates, removing the moisture and stirring uniformly to form adhesive; applying the adhesive to a paper base, drying 60-120 seconds at 80-100 DEG C, heating to 150-180 DEG C again, enabling the adhesive to undergo curing and crosslinking reaction for 90-120 seconds and cooling to wind finally. The high-temperature-resistant paper adhesive tape has the advantages of flexibility in adjustment of peeling force range, resistance to high temperature and lower temperature and excellent anti-ultraviolet performance.

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...
