Abstract

The invention relates to a life reagent-resistant pressure-sensitive adhesive composition and a preparation method of a life reagent-resistant adhesive tape. Through adoption of a soft rubber elastomer polymer modified by a strong polar material and due to good repellency to non-polar greases and solvents, the resistance of pressure-sensitive adhesive coating to life reagents in life can be effectively improved, and the low temperature resistance is relatively good; through adoption of a strong polar tackifying resin system, by virtue of the strong polarity thereof and the insolubility thereofin some solvents, the life reagent resistance of the whole pressure-sensitive adhesive is enhanced again while the whole adhesive system is tackified; the whole rubber elastomer is further crosslinked into a network shape in a thermal crosslinking way, so that the crosslinking density is improved, the intermolecular space is reduced, erosion of life reagent molecules into the adhesive is effectively hindered, and the life reagent resistance of the adhesive is further improved.

Description

technical field [0001] The invention belongs to the technical field of adhesive materials, and relates to a preparation method of a living agent-resistant pressure-sensitive adhesive composition and an adhesive tape thereof. Background technique [0002] Adhesive tape, as an adhesive material, has its special applications, such as fixed bonding of materials, surface protection, etc. With the upgrading of the electronics industry getting faster and faster, the requirements for electronic adhesive tapes are getting higher and higher, and more electronic applications have put forward requirements for tapes that need to be resistant to living substances that they come into contact with in life, such as laundry detergent and sweat. , alcohol, food grease, etc., these are exactly what most ordinary tapes cannot tolerate. According to a research report, a tape company developed a pressure-sensitive tape with good resistance to living reagents by using nitrile rubber, but there wer...
