Background
China is a main manufacturer of the soft furniture, and the main materials of the soft furniture comprise sponge, fabric, leather, wood and the like. With the recent increasing importance of people on high-quality life, the country sets a series of environmental protection and safety policies. The aqueous single-component spray glue has wide application prospect due to environmental protection, safety and convenient operation. The neoprene emulsion is widely applied to soft furniture by virtue of excellent demulsification film-forming property and excellent bonding strength after crystallization, and the acrylate emulsion is a polymer capable of adjusting the proportion of monomers to meet different performance requirements. The acrylate emulsion is compounded, so that the price of the neoprene emulsion can be greatly reduced, and excellent initial viscosity can be provided.
In patent CN108410392A, neoprene emulsions have also been modified with various resins. However, the initial viscosity is still insufficient, so that the production cost is increased by using a demulsifier, and the existing single-component spray glue has the characteristic that the existing single-component spray glue can be sticky only by waiting for a certain period of time to volatilize water.
