High temperature resistant pressure-sensitive adhesive for adhesive tape, adhesive tape and preparation method

Abstract

The invention discloses a high-temperature-resisting pressure-sensitive adhesive for an adhesive tape, the adhesive tape and a preparation process. The high-temperature-resisting pressure-sensitive adhesive comprises main body rubber, an auxiliary material additive, a tackifying agent, a plasticizer, a solvent and a curing agent, wherein the main body rubber is composed of natural rubber and / or synthetic rubber, the auxiliary material additive comprises stannous chloride dihydrate and an anti-aging agent, mass mole ratios of the stannous chloride dihydrate and the anti-aging agent to the main body rubber are 0.2:100-8:100 and 0.1:100-10:100 respectively, the mass mole ratio of the tackifying agent to the main body rubber is 10:100-200:100, and the mass mole ratio of the plasticizer to the main body rubber is 5:100-40:100. The high-temperature-resisting pressure-sensitive adhesive is excellent in initial adhesive performance, high in cohesion, good in stripping performance, high in high-temperature resistance, especially applicable to preparation of masking tapes and capable of greatly facilitating the application of the masking tapes in high-temperature environments.

Description

technical field

[0001] The invention belongs to the field of adhesive tape preparation, and in particular relates to a high-temperature-resistant pressure-sensitive adhesive for an adhesive tape, an adhesive tape and a preparation method, and is especially suitable for preparing masking tape. Background technique

[0002] The tape is mainly composed of a substrate and a layer of adhesive coated on one or both surfaces of the substrate. By forming a bond between the adhesive molecules on the substrate and the surface molecules of the article, the tape is only adhered to on the surface of the item. According to the substrate material, the tape can be divided into kraft paper tape, sealing tape, stationery tape, masking tape, cloth tape, aluminum foil tape, etc. Among them, masking tape (also known as masking pressure-sensitive tape) is made of masking paper and pressure-sensitive adhesive as the main raw materials. The roll-shaped tape made has the characteristics of high te...
