Abstract

The invention relates to a piano lacquer formula with easy defoaming and a production method thereof. The piano lacquer formula comprises the following components: 30 kg of glyceride maleic anhydride resin, 15 kg of styrene, 0.01 kg of polyethylene glycol (600), 1 kg of dibutyltin dilaurate, 2 kg of polyamide wax (a mixture of n-butyl alcohol and naphtha), 50 kg of orthophthalic unsaturated polyester resin, 10.1 kg of polyvinyl butyral, and 0.1 kg of a defoaming hydrophobic solid mixture of polysiloxanes and polyethylene glycol. The production method comprises the following steps: mixing glyceride maleic anhydride resin, styrene, polyethylene glycol (600), dibutyltin dilaurate, and polyamide wax (the mixture of n-butyl alcohol and naphtha), continuously stirring the materials for 30 min, adding orthophthalic unsaturated polyester resin, polyvinyl butyral, polyvinyl butyral, and the defoaming hydrophobic solid mixture of polysiloxanes and polyethylene glycol, and continuously stirring the materials for 30 min.

Description

technical field [0001] The invention relates to the field of chemical paint manufacturing, in particular to a formula for improving the defoaming performance of piano paint and a manufacturing method thereof. Background technique [0002] Now the piano paint on the market generally has the problem of high viscosity and unsatisfactory defoaming effect. After stirring, a large number of bubbles are prone to appear, and it needs to be left for a long time to defoam, which affects the construction time of the piano paint and also easily affects the piano. beautiful. Contents of the invention [0003] The invention solves the problem of poor defoaming of the existing piano lacquer, and invents a formula improved by using a foam breaker and a manufacturing method thereof. [0004] The technical solution of the present invention is a formula for solving the problem of defoaming of piano lacquer and its manufacturing method, including: dehydrated malic acid resin, styrene, polyet...
