Abstract
The invention discloses a coating for a high-fullness PU finishing varnish electric vehicle plastic part, and is characterized in that the coating comprises the following components by the mass percentage: 70-80% of high hydroxyl polyurethane acrylic resin, 10-20% of butyl acetate, 1-3% of a leveling agent, 1-3% of a defoaming agent, 2-6% of a drier and 1-3% of an adhesion promoter. At the same time, the invention also discloses a preparation method of the coating. Compared with the prior art, the serious quality problem of durability of a traditional electric vehicle plastic part coating finishing varnish is mainly solved while beautiful appearance performance requirements increasingly required for electric vehicle main engine plants at present are met.
Description
Technical field
The invention belongs to chemistry painting industry field, and in particular to one kind is used for high richness PU coating varnishes electric motor car working of plastics
Coating and preparation method thereof.
Background technology
At present, at home the processing enterprise of electric motor car application is all flowing to market process when using coating for the product later stage
UV photocuring coating varnish technology unstability, PU coating varnishes richness difference and the bad situation of drying property and worry market rope
Compensation, occupation rate of market：At present the appearance member used by electric motor car producer is all ABS parts（Working of plastics）, electric motor car market is competing in recent years
Strive abnormal fierce, more and more higher is required to product appearance and color, brand awareness is more and more stronger, in whole electric vehicle, sale, visitor
During the use of family, not only to keep product quality, for outward appearance richness, clarity, durability can not be over time
Elapse and disappear, it is plentiful that this traditional UV photocureable coating itself itself has certain endurance issues, PU coating varnishes
The problems such as degree poor, underdry, in sum, the above-mentioned coating varnish of traditional electric motor car cannot meet the application of electric motor car market,
Car load, sale etc. need.
The content of the invention
Goal of the invention：Present invention aims to the deficiencies in the prior art, there is provided a kind of for high richness PU covers
The coating of light varnish electric motor car working of plastics.
Another object of the present invention is to provide the preparation method of above-mentioned coating.
Technical scheme：In order to reach foregoing invention purpose, what the present invention was specifically performed by：One kind is for high plentiful
The coating of degree PU coating varnish electric motor car working of plastics, it is characterised in that including the component of following mass percent：70 ~ 80% height
Hydroxyl polyurethane acrylic resin, 10 ~ 20% butyl acetate, 1 ~ 3% levelling agent, 1 ~ 3% defoamer, 2 ~ 6% drier and 1
~ 3% adhesion promoter.
Wherein, high hydroxyl polyurethane acrylic resin solid content >=70%, remaining is butyl acetate and propylene glycol monomethyl ether vinegar
Acid esters.
Wherein, the levelling agent for BYK companies the polyether-modified polymethyl siloxane solution of BYK-320, its mass concentration
≥52%。
Wherein, the defoamer for BYK companies the special fluorine richness organic silicon solutions of BYK-054, its mass concentration >=
25%。
Wherein, the drier for U.S.'s gas companies T-12 dibutyl tin laurates, its mass concentration >=0.5%.
Wherein, the adhesion promoter for this company of hamming ADP do not contain polysiloxane compound, its mass concentration >=
78%。
For the preparation method of the coating of high richness PU coating varnishes electric motor car working of plastics, comprise the following steps：
（1）The high hydroxyl polyurethane acrylic resin of formula ratio, butyl acetate are added in painting cylinder, in 500～800 revs/min of rotating speeds
Lower stirring 10～15 minutes；
（2）The defoamer of formula ratio, levelling agent and adhesion promoter are walked into addition suddenly（1）Solution in, 600～900 turns/
Divide mixing time 10～15 minutes under rotating speed；
（3）Drier is eventually adding, is stirred 20 ~ 30 minutes at 600～900 revs/min, barrelling.
Beneficial effect：The present invention is increasingly required beautiful current electric motor car main engine plants are met compared with conventional art
Appearance property requires outer main to solve traditional electric car working of plastics coating coating varnish in durability serious quality problems.
