Abstract

The invention discloses a cross-linked rubber adhesive. The cross-linked rubber adhesive is prepared from, by mass, 12-18% of star type SIS, 12-18% of polyterpene A, 1-5% of polyterpene B, 0.05-0.15%of a polyfunctional group monomer, 0.6-1.4% of hollow glass microspheres, 0.01-0.1% of a dispersing agent, 0.02-0.05% of a photoinitiator, 0.02-0.1% of a light stabilizer, 0.1-0.2% of an antioxidant and 50-70% of a solvent. The cross-linked rubber adhesive and high-bonding-strength shock absorbing and silencing tape applying the rubber adhesive have the advantages of water prevention, shock absorption, sound attenuation, high bonding strength, excellent aging performance and good subsequent die cutting processing performance, and can be used as double-sided adhesive tape in the fields of someautomobiles and electronics well.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a cross-linked rubber adhesive, a high bonding strength shock-absorbing and sound-absorbing adhesive tape using the adhesive and a preparation method thereof. Background technique [0002] With the rapid development of industrial products, ranging from spacecraft, automobiles, to notebook computers, mobile phones, etc., more and more occasions require adhesives or adhesive tapes to provide bonding functions, especially for high bonding strength, durable The requirements for high and low temperature performance, waterproof performance, shock absorption and sound insulation performance are getting higher and higher. High and low temperature resistance mainly refers to ensuring that the adherend does not fall off and has a certain bonding strength under high or low temperature environments. Waterproof performance mainly refers to preventing water from penetrating from ...
