Abstract

The invention relates to the fields of adhesives and particularly relates to an ageing resistant and hardening resistant double-component waterborne adhesive spray. The ageing resistant and hardening resistant double-component waterborne adhesive spray comprises a component A and a component B, wherein the component A comprises the following components by weight: 39-41 parts of a waterborne chloroprene rubber emulsion, 30-40 parts of an acrylic emulsion, 7-9 parts of waterborne terpene tackifying resin, and 2-10 parts of sodium dodecylbenzene sulfonate; the component B comprises the following components by weight: 5-10 parts of rosin resin, 1-5 parts of isocyanate, 1-3 parts of gel amorphous silica, and 30-40 parts of deionized water. The adhesive spray has an excellent ageing resistance property, and has quite excellent effects of bonding strength, speed and stability on leather and sponges.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an anti-aging and anti-hardening two-component water-based spray glue and a preparation method thereof. Background technique [0002] Two-component spray glue is mainly used for bonding between sponge, wood, leather, cloth, foam and other materials, especially for the curved bonding of sponge and leather, sponge and wood board. The existing two-component spray glue urgently needs to solve the following problems: After the traditional two-component spray glue is connected and cured, the glue layer is easy to harden, especially the hardening at the edge of the joint is particularly serious; in addition, for oily leather and imitation leather materials , The traditional spray glue has poor oil resistance, especially the initial adhesion and final adhesion are not ideal, which directly affects the firmness and stability of the arc bonding between leather and sponge.
