Abstract
The invention discloses a high-solid-content polyurethane adhesive for a composite board and a preparation method of the high-solid-content polyurethane adhesive. The high-solid-content polyurethane adhesive is prepared from the following raw materials in parts by weight: 60 to 70 parts of polycaprolactone diol, 20 to 22 parts of methylene diphenyl diisocyanate, 13 to 15 parts of toluene diisocyanate, 85 to 95 parts of polytetrahydrofuran ether diol, 14 to 16 parts of ethylene glycol, 3 to 5 parts of dipropylene glycol dibenzoate, and the like. According to the high-solid-content polyurethane adhesive and the preparation method thereof disclosed by the invention, polyurethane is physically modified by using polymer bisphenol A type epoxy vinyl ester resin, and the solid content of the polyurethane is increased by using a co-emulsifying action of polymer emulsion; added polyvinyl acetal is bound with a polyurethane molecular chain, so that the hydrophily of a water-borne polyurethane coating film is enhanced, and the water resistance of the adhesive is greatly improved; a cross-linking agent trimethylolpropane and abies balsam are adopted to react with a polyfunctional group on a polyurethane dispersion, so that the polyurethane which is originally linear forms a cross-linking reticular structure with a certain degree, and further the bonding strength of the adhesive can be improved.
