Abstract

The invention relates to a spray adhesive and a preparation method thereof. The spray adhesive comprises the following components in parts by weight: 10-20 parts of synthetic rubber, 30-65 parts of tackifying resin, 0.1-0.5 parts of a bridging agent, 20-55 parts of organic solvent, and 0.1-5 parts of an anti-permeation agent. The spray adhesive has the following beneficial effects that the solvent system is environment-friendly, low in smell and fast to dry after the adhesive is spayed; the construction application performance is good; the comprehensive performances is good, such as bonding strength, open time and the like are excellent.

Description

technical field [0001] The invention relates to a rubber-type adhesive, in particular to a spray glue with good anti-permeability, and also relates to a preparation method of the spray glue. Background technique [0002] At present, common spray glue is mainly composed of synthetic rubber, tackifying resin, organic solvent, additives and other materials. It has the characteristics of simple preparation process, low viscosity, good sprayability, and wide application range. It is mainly used for sofas, furniture, sponges, etc. , luggage, fabric and other fields, favored by the market. [0003] However, due to the requirements of the construction process, the viscosity of the spray glue should not be too high, and a large amount of solvent must be used for dilution in the formula design. However, when ordinary spray glue is applied to the bonding of loose materials such as fabrics, it often occurs The glue penetrates to the back of the sticky material, seriously affecting the ...
