Problems solved by technology

Polyacrylic (ester) pressure-sensitive adhesive and self-adhesive polyethylene protective film are difficult to peel off after the panel is pasted, and are not suitable for laser cutting, deep drawing, bending, etc. Type selection is unfavorable for use; while rubber-type pressure-sensitive adhesives have poor adhesion on polye

Embodiment 1

[0018] 30 parts of natural rubber and 5 parts of synthetic rubber are masticated with a rubber mill until the Vickers plasticity reaches 0.5-0.6, and matured for 12-24 hours, and the matured natural rubber and synthetic rubber are mixed with 4 parts of composite anti-aging agent , 0.2 parts of vulcanizing agent are mixed with a rubber mill and thinly passed 3-5 times, and added to the dispersion reactor with nitrogen protection, and 120 parts of solvent, 5 parts of adhesion promoter, and 6 parts of mixing aid are added at the same time. agent, cool to room temperature when a uniform solution is formed, and filter to obtain the rubber-type pressure-sensitive adhesive.

Embodiment 2

[0020] Use a rubber mill to masticate 50 parts of natural rubber and 50 parts of synthetic rubber until the Vickers plasticity reaches 0.5-0.6, and mature for 12-24 hours. Mix the matured natural rubber and synthetic rubber with 6 parts of composite anti-aging agent , 3 parts of vulcanizing agent are mixed with a rubber mill and thinly passed 3-5 times, and added to the dispersion reactor with nitrogen protection, and 700 parts of solvent, 15 parts of adhesion promoter, 30 parts of mixing aid are added at the same time agent, 100 parts of tackifying resin, cool to room temperature when a uniform solution is formed, and filter to obtain the rubber-type pressure-sensitive adhesive.

Embodiment 3

[0022] Plasticize 40 parts of natural rubber and 15 parts of synthetic rubber with a rubber mill until the Vickers plasticity reaches 0.5-0.6, and ripen for 12-24 hours, mix the cured natural rubber and synthetic rubber with 6 parts of composite anti-aging agent , 1.8 parts of vulcanizing agent are mixed with a rubber mill and thinly passed 3-5 times, and added to the dispersion reactor with nitrogen protection, and 400 parts of solvent, 10 parts of adhesion promoter, 8 parts of mixing aid are added at the same time agent, 40 parts of tackifying resin, cool to room temperature when a uniform solution is formed, and filter to obtain the rubber-type pressure-sensitive adhesive.

Abstract

The invention relates to a rubber type pressure-sensitive adhesive for a polyethylene protective film and a preparation method thereof. The rubber type pressure-sensitive adhesive comprises the following components in parts by weight: 30-50 parts of natural rubber, 5-50 parts of synthetic rubber, 0-100 parts of a tackifying resin, 4-6 parts of a composite anti-aging agent, 5-15 parts of an adhesion promoter, 0.2-3 parts of a vulcanizing agent, 120-700 parts of a solvent, and 6-30 parts of a mixed additive. The rubber type pressure-sensitive adhesive is applied to the polyethylene protective film, so that the surfaces of plastics, metal plates, spraying plates, glass, marble, especially fluorocarbon paint and the like are protected at very low peeling strength. In addition, the primer coating and the release agent coating (except the surface needing to be printed) are not needed during coating.
