Description
Technical field
The invention belongs to woodwork coating manufacturing industry, be specifically related to a kind of there is the PU dumb light flour that gloss is the most smooth
Paint research and development.
Background technology
Common PU matte white finish is when spraying, and all coating technology practitioners both know about gloss paint film delustring mainly
Use aerosil, but due to the self character of aerosil, thus, it is by construction technology, drying time, ring
The impact of the factor such as environmental temperature and humidity, result of prevention is big, particularly when producing the white finish paint of low gloss, if aerosil is used
Amount is big, and lustre lacking uniformity easily occurs in paint film, the film defect such as grow dim；Organosilicon and wax powder is used to be suspended in paint film top layer and provide
Feel, paint film on furniture as time went on, use during constantly friction, after paint film abrasion is old, organosilicon and wax
The silk wiping sense of the given film of powder will disappear.Along with top-grade furniture is increasingly liked by consumer, coating specification the most constantly carries
Rising, common PU dumb light can not meet the most far away clearly high-grade application demand.
The present invention is to utilize the easy delustring of high molecular short oil alkyd resin, the feature of fast drying, spells with 1451 light trimerizations
Body firming agent, HDI trimer firming agent, make paint film have excellent lifting in rate of drying, flexibility, by adding
The vinyl chloride-vinyl acetate resin solution of 20% solid content improves the resistance to of paint and opens dilute performance, helps delustering agent arrangement uniformly, utilizes PE delustring
Wax self the smooth feature that suspends of slurry, collocation is a small amount of containing the flatting silica of Lasaxing Oilfield, polytetrafluoroethylwax wax, the making of organosilicon auxiliary agent
With, in raising, powder anti-settling, mute is evenly distributed, give the paint film smooth effect from surface to nexine simultaneously, will not be because of paint film top layer
Rub and lose smooth effect, prepare and there is the PU matte white finish finish paint product that gloss is the most smooth.
Summary of the invention
It is an object of the invention to: for above-mentioned the deficiencies in the prior art, it is provided that a kind of to have gloss the most smooth
