Abstract

The present invention belongs to the field of adhesives, and proposes a two-component butyl rubber adhesive, including material A and material B; the material A includes the following components in parts by weight: 100 parts of butyl rubber; 3 parts of zinc oxide ‑5 parts; 10‑20 parts of polyacrylic resin; 2‑4 parts of stearic acid; 20‑40 parts of rosin glyceride; 400‑500 parts of n-hexane and ethyl acetate mixed solvent with a volume ratio of 1:0.3; The B material includes the following components by weight: 100 parts of butyl rubber; 70-85 parts of carbon black; 3-5 parts of zinc oxide; 1-3 parts of sulfur; a mixture of n-hexane and ethyl acetate with a volume ratio of 1:0.3 Solvent 300‑400 parts. The viscosity of the two-component butyl rubber adhesive of the present invention is greater than 1.5KN / m during use, and can reach 1.7K.N / m-1.9K.N / m.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a two-component butyl rubber adhesive and a bonding method. Background technique [0002] Butyl rubber adhesives are often used in pressure-sensitive adhesives or sealants. Its main advantages are good airtightness, easy and effective dispersion in organic solvents, and transportation and storage in the form of liquids. [0003] The bonding particle size of the existing butyl rubber is generally lower than 1.5KN / m, and its bonding strength is low, which only shows that the bonding strength to leather is strong, and the bonding strength to leather, plastics and steel is small. Contents of the invention [0004] The invention aims to provide a two-component butyl rubber adhesive and a bonding method with high bonding force. [0005] The specific plan is: a two-component butyl rubber adhesive, including material A and material B; [0006] Described A material comprises following compone...
