Abstract

The invention provides a thermo-cycling and non-blushing PE varnish and belongs to the field of chemical coatings. The thermo-cycling and non-blushing PE varnish is prepared from the following four components of A, B, C and D, wherein the component A is prepared from air-dried unsaturated polyester resin, a leveling agent, 0 to 0.2 percent of a defoaming agent, 0 to 5 percent of an anti-settling agent, styrene, 0 to 0.5 percent of a dispersing agent, a polymerization inhibitor and 0 to 50 percent of a filler; the component B is prepared from the styrene, xylene, ethyl ester, the polymerizationinhibitor and dimethyl carbonate; the component C is cobalt iso-octoate containing 6 percent of cobalt by mass fraction; the component D is methyl ethyl ketone peroxide. As the air-dried unsaturatedpolyester resin and various aids which have good compatibility with a resin system are selected, the obtained thermo-cycling and non-blushing PE varnish disclosed by the invention has the advantages of high gloss of a formed film, good transparency of the varnish film, thermo-cycling resistance and no blushing phenomenon after being stored for several months.

Description

technical field [0001] The invention belongs to the field of chemical coatings, and in particular relates to a PE varnish which does not turn white in cold and hot cycles. Background technique [0002] Unsaturated polyester paint is used in wood coatings because of its high solid content, high hardness, excellent sag resistance, good filling, high fullness, time-saving, labor-saving and low cost in construction. are used extensively. However, many transparent lacquer products currently used have poor aging resistance after film formation, and often have the phenomenon of whitening after the product is placed for several months, which reduces the grade of the product and causes the product to be scrapped. Contents of the invention [0003] The object of the present invention is to provide a PE varnish that does not turn white in cold and hot cycles in order to overcome the above-mentioned deficiencies in the background technology. [0004] In order to achieve the purpose ...
