Problems solved by technology

[0003] The traditional solvent-based spray glue has such defects, that is, due to the use of a large amount of organic solvents, it can only meet the general standards such as the national standard GB 18583-2001 in terms of environmental protection index, and it is still difficult to meet high environmental protection standards such as China's environmental label certification standard HJ / T 220-2005, IKEA standard, German Blue Angel environmental protection standard, etc. In terms of application performance such as holding force, heat resistance and aging resistance, opening time, etc., it needs to be optimized and improved to meet the performance needs of the high-end market

Description

technical field [0001] The invention belongs to the technical field of adhesives, and more specifically relates to a water-based neoprene spray glue and a preparation method thereof. Background technique [0002] Spray glue is a kind of adhesive with suitable viscosity, which is suitable for spraying gun as a construction tool, and closely connects two different material interfaces to play the role of transfer application; spraying construction is often more efficient than traditional brushing construction methods. It can save time, labor, glue, and increase efficiency, and has the effect of getting twice the result with half the effort. Glue spraying has been widely used in thick leather, genuine leather, imitation leather, recycled leather, sponge, cloth, wood, metal, stone, shoes Bonding between wood and other materials; spray glue includes solvent-based spray glue (oil-based spray glue) and water-based spray glue, of which the Chinese market is still dominated by solvent...
