According to the technology effect of the invention, through adoption of a formula and a preparation method of paint, surface tension of coating bubbles can be changed to make bubbles broken rapidly so as to achieve a defoaming objective, thus ensuring a rapid coating construction process and preventing construction delay caused by waiting for defoaming.
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 polyurethane cabinet paint and a manufacturing method thereof. Background technique [0002] The polyurethane cabinet paints on the market now generally have the problems 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 cabinet paint and also easily affects cabinets. beautiful. Contents of the invention [0003] The invention solves the problem of poor defoaming of the existing polyurethane cabinet paint, and invents a formula improved by using a foam breaker and a manufacturing method thereof. [0004] The technical scheme of the present invention is, a kind of formula and its manufacture method that solves polyurethane cabinet paint defoaming badly, compri...
