Description
Technical Field
The invention relates to the technical field of adhesives, in particular to a non-powdering spray adhesive for single-component polyurethane furniture and a preparation method thereof.
Background
Most of spray glues for furniture manufacture in the market are prepared from styrene-butadiene-styrene block copolymer (SBS) and tackifying resin, and water-based neoprene spray glues and oil-based neoprene spray glues are used in a few occasions. According to tests, the phenomenon that the glue layer of SBS sprayed glue on the market is easy to pulverize after bonding and curing, most of sprayed glue is pulverized within 10-15 days even under the condition that indoor solar irradiation is not carried out, if the sprayed glue is irradiated by the sun for 2-6 hours basically, the pulverized glue is serious, and the phenomenon of pulverization is found in the sponge when some furniture is not completely made into finished products, so that the inherent quality of the furniture is seriously influenced. In order to avoid the situation, some high-grade furniture factories select aqueous neoprene spray glue and oily neoprene spray glue which are not convenient in technological operation, and the aqueous neoprene spray glue has complex equipment, poor bonding hand feeling, high cost and poor low-temperature adaptability; the oil neoprene spray glue generally contains toxic solvents such as toluene, chlorohydrocarbon and the like when being dissolved, has the defects of large spray smell, large harm to human bodies, high cost and the like, and the water neoprene spray glue and the oil neoprene spray glue have the biggest advantages of good heat resistance and particularly good pulverization resistance, but cannot be compared with SBS spray glue in the aspects of cost, environmental protection and actual bonding operability. The existing SBS glue spraying technology actually uses SBS modified tackifying resin, the tackifying resin accounts for the main mass, a small amount of SBS plays a toughening role, the tackifying resin is relatively brittle, and the tackifying resin is easy to pulverize after accelerated aging by solar irradiation.
