Abstract
The invention relates to a high-rigidity reinforcement-bulging-resistant PU (Poly Urethane) crystal transparent primer coating. The PU crystal transparent primer coating is prepared from the components in percentage by weight: 25-30 percent of acid-alcohol resin, 40-50 percent of modified acrylic resin, 3-5 percent of zinc stearate, 10-15 percent of glass powder, 0.2-0.4 percent of additive and 7-10 percent of solvent. Due to adoption of the special modified acrylic resin, the high-rigidity reinforcement-bulging-resistant PU crystal transparent primer coating has the advantages of small molecular weight, strong rigidity, rapidness in drying and solvent dilution and the like; and as the glass powder with strong rigidity, good transparency and good fallibility, as well as a curing agent and a diluent with a proper proportion are used, and thus the PU crystal transparent primer with strong rigidity, rapidness in drying, good fillibility and high transparency is prepared, so that furniture products made of deep wooden eye wood such as meander belts, ebonies and the like, which have the problems of reinforcement bulging, collapse, poor transparency and the like, can be solved, the quality and the market value of the deep wooden eye furniture products are greatly improved, and the requirements of consumers and the market are satisfied.
Description
Technical field:
The present invention relates to the chemistry painting industry technical field, the PU crystal that refers in particular to the anti-bulging muscle of a kind of high rigidity reveal the exact details lacquer coating and priming paint.
Background technology:
Adopt the top-grade furniture of the materials such as Qu Liu, ebony quite a lot of in the furniture market at present, the wood eye of this class timber is darker, when japanning, existing paint fillibility is bad, is difficult to fill dark wood eye, and cause after the filling can the drum muscle, the phenomenon such as subside again behind the complete drying, if and adopt the more priming paint of powder, can make again the transparent variation of filming, above-mentioned phenomenon all so that the quality of furniture item descends, is difficult to meet human consumer's requirement.
Summary of the invention:
The object of the invention is to overcome when existing paint is used for the dark timber product japanning of wood eye and easily produce the drum muscle, subside and the weak point such as poor transparency, a kind of high rigidity, anti-bulging muscle and the good PU crystal of the transparency reveal the exact details lacquer coating and priming paint are provided.
The present invention realizes that the technical scheme that its purpose adopts is: reveal the exact details lacquer coating each component and mass percentage content thereof of the PU crystal of the anti-bulging muscle of a kind of high rigidity lacquer coating of revealing the exact details, this PU crystal is: alkyd resin 25%-30%, acrylic resin modified 40%-50%, Zinic stearas 3%-5%, glass powder 10%-15%, auxiliary agent 0.2%-0.4%, solvent 7%-10%.
