Abstract
The invention relates to an anti-sinking poly ethylene (PE) super-clear base coat. The anti-sinking PE super-clear base coat comprises a component A and a component B, wherein the component A is prepared from unsaturated polyester resin, a dispersing agent, a flatting agent, an antifoaming agent, hydroquinone, superfine silicon dioxide, pigment, nitrocotton, unsaturated quick-drying polyester resin and the like as well as an environment-friendly solvent; the component B is prepared from solvents such as n-butyl acetate, absolute ethyl alcohol and dimethyl carbonate. The anti-sinking PE super-clear base coat, which is good in anti-sinking property, high in transparency and easy to polish, is prepared by completely and uniformly stirring the component A and the component B with colorless and transparent cobalt water in a certain ratio, adding methyl ethyl ketone peroxide in a certain proportion to be stirred completely and uniformly. Detection and trial prove that all the performance indexes meet national standards and enterprise standards which are recorded nationally (standard number: Q/BDSH003-2008 and record number: QB/442000 87 259-2008); the base coat has good levelling, quick defoaming, low odor and quick drying velocity during the construction; and a coating layer has the characteristics, which are beyond the similar PED super clear bases, of good anti-sinking performance, high greening resistance, excellent transparency, thick coating capability and the like, and is easy to grind. The anti-sinking PE super-clear base coat disclosed by the invention is widely popular with costumers.
