Abstract

The present invention discloses a novel high sealing property unsaturated polyester white primer, and a preparation method thereof. The unsaturated polyester white primer provided by the present invention comprises, by weight, 40-45% of unsaturated polyester PE resin, 0.2-0.3% of an antifoaming agent, 0.3-0.5% of a wetting dispersant, 0.2-0.3% of a polyacrylate leveling agent, 0.1-0.2% of an anti-green agent, 4-6% of organic bentonite pre-clotting slurry, 0.2-0.8% of fumed silica, 3-7% of zinc stearate, 3-9% of 1250 mesh pulvistalci, 7-11% of 800 mesh pulvistalci, 13-21% of ground calcium carbonate, 11-17% of rutile titanium dioxide, 2-5% of a nitrocellulose solution and 1-3% of n-butyl acetate. The unsaturated polyester PE primer provides especially good sealing property for the low density medium density fiberboard, wherein the low density medium density fiberboard is not subjected to a sealing treatment or is treated bad. In addition, the unsaturated polyester PE primer has characteristics of excellent caving resistance, excellent sagging resistance, short polishing time, good polishing property, strong interlayer adhesion, and can be applicable for the comprehensive primer solution schemes for different environments, various processes and plates.

Description

Technical field [0001] The invention involves a unsaturated polyester white primer for wood painting, especially a new high -enclosed unsaturated polyester white primer and a new high -enclosed unsaturated polyester white primer and a low -density in low density.Its preparation method. Background technique [0002] At present, there are many types of unsaturated polyester paint for wood painting, especially in unsaturated polyester white primer.There are many technical requirements for unsaturated polyester white primer, and the advantages of good closure, good filling, good anti -sinking, excellent anti -flow hanging, short polishing time, excellent polishing, strong intercourse, excellent covering power and other advantagesEssenceHowever, these unsaturated polyester white primer has limited closure, non -current, and polishing time due to the limitation of the closed mechanism used, and especially the low -density of the low density of the low -density of unscrupulous treatment...
