Problems solved by technology

Modern industry requires that the adhesive tape does not adhere to the surface of the electronic components to be bound, and only the adhesive layer at the place to be bonded is bonded together by pressure. The disadvantage of conventional adhesive tape is that the adhesive will stick to the electronic components and cause It is difficult to peel off, and at the same time, there will be adhesive left on the electronic components to contaminate the components or the strength of the adhesive is too strong to cause the substrate to tear

Embodiment 1

[0019] Add 0.1 part (weight) of commercially available rubber anti-aging agent in 20 parts (weight) of acetic acid and (meth)acrylic acid ester monomer copolymer with a solid content of 45%, and add a natural rubber latex with a solid content of 60% after stirring 100 parts (weight), add soft water or distilled water 40 parts (weight) again, be made into viscose liquid. Coat the formulated adhesive solution at 60g / m 2 On the surface of the paper substrate, the thickness of the coating layer is 8~29g / m 2 (solid content) is better, and then all or most of the water in the coating is evaporated by heat drying, and then cut into cold-pressed self-adhesive tapes according to the length and width required by the user. Example 2

Embodiment 2

Abstract

The cold-pressurized adhesive paper tape consists of paper substrate and adhesive layer painted onto the surface of the paper substrate. The adhesive consists of natural latex of a 60% solid content, copolymer of vinyl acetate and acrylate and with a 45% solid content, soft water or distilled water and marketable rubber antiager. The cold-pressurized adhesive paper tape is mainly used in producing braid for film capacitor, resistor and other small electronic elements. It has proper adhering strength and will not produce residual on electronic elements and pollutant to other article.

Description

Technical field [0001] The invention relates to a self-adhesive tape paper. Background technique [0002] At present, self-adhesive tape paper is mainly used for the braiding of small electronic components such as film capacitors and resistors. It is produced under a certain pressure when the adhesive layer faces the adhesive layer after coating the adhesive layer on the strong paper base. Self-adhesive, but the adhesive layer is a special industrial paper that does not bond to other substances (such as paper, plastic, polyethylene, polyvinyl chloride, metal, etc.). Modern industry requires that the adhesive tape does not adhere to the surface of the electronic components to be bound, and only the adhesive layer at the place to be bonded is bonded together by pressure. The disadvantage of conventional adhesive tape is that the adhesive will stick to the electronic components and cause It is difficult to peel off, and at the same time, there will be adhesive left on the elec...
