Description
Technical field
The present invention relates to finishing varnish and preparation method thereof, be specifically related to hydroxy acrylic acid car repair dedicated hood lac varnish and
Preparation method.
Background technology
Acrylic coating is just with traditional solvent-borne type hydrotropism's paint development, the existence energy of solvent based coating the most both at home and abroad
Enough improve paint industry further, market is had certain meaning.
Hydroxy acrylic acid finishing varnish is a lot of on the market at present, is widely used on bumper, but hydroxyl on the market
Acrylic based finishing varnish, hardness is high, and major part varnish can not recoat.Recoating attachment can fall paint.
Summary of the invention
The technical problem to be solved, is to provide a kind of hydroxy acrylic acid car repair dedicated hood lac varnish, this cover
Lac varnish has raising, improves the adhesive force of product.
The present invention also to solve the technical problem that the preparation being to provide above-mentioned hydroxy acrylic acid car repair dedicated hood lac varnish
Method.
For solving above-mentioned technical problem, the technical solution used in the present invention is as follows:
Hydroxy acrylic acid car repair dedicated hood lac varnish, it includes the component of following parts by weight:
Above-mentioned hydroxy acrylic acid car repair dedicated hood lac varnish, preferably includes the component of following parts by weight:
Wherein, described solvent is dimethylbenzene, acetate butyl, acetic acid fat, S100 aromatic solvent
The not only environmental protection of these solvents, and deep layer surface quality and good product construction ring can be significantly improved
Border.
Wherein, described Hydroxylated acrylic resin is 2-Hydroxy ethyl acrylate (HEA), 2-hydroxypropyl acrylate
(HPA), these Hydroxylated acrylic resins have richness, gloss and the chemical property of excellence.
Wherein, the described Hydroxylated acrylic resin that modified resin is polyester modification.Modified resin has large arch dam, Gao Guang
Damp and good pliability.
Wherein, described drier is lauric acid organotin or maleate organotin.These drier have promotion hydroxyl
Base acrylic resin and firming agent cross-link more completely.
Wherein, the mixing of the described Hydroxylated acrylic resin that resist sagging resin is polyesteramide and polyester modification
Thing, preferably mixes according to the weight ratio of 1:1.These resist sagging resins have resist sagging performance and the high-luster and dust-proof of excellence
Effect.
Wherein, described levelling agent is modified organic silicon, fluorine-carbon modified polyacrylate or modified organopolysiloxane
Poly-isocyanide alcohol ester.Levelling agent has extraordinary levelling effect to apparent condition in work progress so that paint film more satin.
The preparation method of above-mentioned hydroxy acrylic acid car repair dedicated hood lac varnish, comprises the steps:
(1) by the solvent of formula ratio, Hydroxylated acrylic resin, modified resin and resist sagging mixed with resin, per minute
Stir 10-20 minute under the rotating speed that 800-1000 turns so that it is mix homogeneously；
(2) in the system that step (1) obtains, add drier and the levelling agent of formula ratio, stir under same rotating speed
20-30 minute.
Beneficial effect: hydroxy acrylic acid car repair hub dedicated hood lac varnish of the present invention can reach three recoatings
Adhesive force is good.And having the thickness of excellence, glossiness, hardness, solvent resistance, weatherability, at high temperature invariant color is not returned
Huang, can extensively send out and apply on the product such as automobile, bicycle.Hydroxy acrylic acid car repair hub dedicated hood of the present invention
Lac varnish can pass through the known coating process two such as such as aerial spraying, classical spraying and use.The thick end of solidification coating, is usually
15-100 micron, even have for 20-50 micron.Be dried the temperature bakeed being 60-80 DEG C is 30 minutes.
