Abstract
The invention discloses a kind of automobile Environment-friendlywear-resistant wear-resistant coating, it is made of following raw material: 50-60 parts of modified polyester resin, 2.5-3 parts of wear resistant filler, lubrication filler 1-1.5 parts, 1-1.6 parts of curing agent, 0.2-0.3 parts of defoaming agent, 0.3-0.4 parts of anti-settling agent, 0.2-0.3 parts of levelling agent, 0.1-0.2 parts of ultraviolet absorbing agent, 5-8 parts of styrene, 40-50 parts of n,N-Dimethylformamide；The invention also discloses the preparation methods of the coating.For coating of the invention using modified polyester resin as coating film forming matrix, modified polyester resin has the performances such as preferable water-fast, wear-resisting, impact resistance；It joined wear resistant filler, can not only preferably be scattered in resin matrix and play the role of receiving and distractive load, and even closer inorganic/organic coating can be generated with resin, enhance coating wear resistance；A kind of coating with excellent wear-resisting property and water resistance is obtained, can satisfy the spraying process requirement of automobile in the production line.
Description
Technical field
The invention belongs to Painting Technology for Automobile fields, and in particular, to a kind of automobile Environment-friendlywear-resistant wear-resistant coating and its preparation
Method.
Background technique
Automobile is travelling on the way, and the positions such as wheel cover, car bottom plate, lower stringer, mud guard and vehicle door pedal are easy by sand
The impact of stone is easily damaged these positions and causes to corrode, to bring driving hidden danger.Therefore, to these positions of automobile into
Row protection seems extremely important and necessary, and the guard method being often used is to coat wear-resistant paint at these positions.
Existing coating can have the following disadvantages: non-refractory, for a long time in the case where burning sun is exposed to the sun, it may occur that cracking, takes off blistering
It falls；Waterproofness is poor, is easy to cause inside to be corroded by rain penetration；It intolerant to colliding with, wears no resistance, poor adhesive force is accidentally cut to pieces
After rubbing, it may appear that depainting phenomenon, and then be easy to be corroded, to influence vehicle body appearance and service life.
Summary of the invention
The purpose of the present invention is to provide a kind of automobile Environment-friendlywear-resistant wear-resistant coating and preparation method thereof, using modified polyester resin
Rouge has the performances such as preferable water-fast, wear-resisting, impact resistance as coating film forming matrix, by modified polyester resin；?
It joined wear resistant filler in coating, wear resistant filler can not only be preferably scattered in resin matrix, play receiving and distractive load
Effect, and the C=C double bond that mixed fillers surface after modified is introduced into can crosslink instead with unsaturated bond in resin
It answers, generates even closer inorganic/organic coating, greatly strengthen the wear-resisting property of coating；Also, coating is during the preparation process
Volatile organic gas will not be generated, environmental protection concept is met；It obtains a kind of with excellent wear-resisting property and water resistance
Coating can satisfy the spraying process requirement of automobile in the production line.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of automobile Environment-friendlywear-resistant wear-resistant coating, is made of following raw material: 50-60 parts of modified polyester resin, wear-resisting
2.5-3 parts of filler, filler 1-1.5 parts of lubrication, 1-1.6 parts of curing agent, 0.2-0.3 parts of defoaming agent, 0.3-0.4 parts of anti-settling agent, stream
Flat agent 0.2-0.3 parts, 0.1-0.2 parts of ultraviolet absorbing agent, 5-8 parts of styrene, 40-50 parts of N,N-dimethylformamide；
The preparation method of the automobile Environment-friendlywear-resistant wear-resistant coating, includes the following steps:
Step S1, modified polyester resin is added in n,N-Dimethylformamide, heating makes it dissolve；
