Abstract

The invention relates to modified woodenware polyurethane gloss black finish paint compose of components A, B and C. When in use, 1 part of A by weight, 1 part of B by weight, and 0.4 to 0.6 parts of C by weight are blended. (1) Component A comprises U2814, black finish slurry, n-butyl acetate, cyclohexanone, xylene, an antifoaming agent, a leveling agent, and an anti-scratching agent, wherein the materials are formulated according to weight percentages. The materials are uniformly dispersed until the fineness is 20mum or less and the viscosity is 2000 to 2500CPS / 25 DEG C. (2) Component B comprises n-butyl acetate, HI190, B1451 and L-75, wherein the materials are formulated according to weight percentages. The materials are dehydrated, the temperature is maintained at 70 DEG C, then the temperature is reduced, and the materials are sealed. (3) Component C comprises n-butyl acetate and xylene, wherein the materials are formulated according to weight percentages. As results of testing and probation, the finish paint has advantages of excellent wear-resistance and anti-scratching capacity, strong adhesive force, high hardness, good heat resistance, good fullness, good constructing and levelling property, and an environment protecting performance satisfying a standard GB18581-2009.

Description
