Abstract
The invention relates to a coating of electric vehicle exterior GFRP (glass fiber reinforced plastic) parts. The coating comprises the following components by weight percent: 40-45% of polyurethane resin, 18-20% of melamine resin, 20-25% of pigment, 3-6% of an assistant, 8-10% of a xylene solvent, and 2.5-3.5% of No.150 solvent, wherein the assistant comprises one or more of a defoamer, a levelling agent, an adhesion promoter, a dispersing agent, an anti-settling agent, and the like. According to the coating of electric vehicle exterior GFRP parts, the inner chemical structure and molecular structure of the coating are effectively adjusted, and the coating contains 15000-30000 molecules, so that the adhesive force of the coating is improved after secondary coating, and relatively high bonding strength is achieved; besides, during repairing and recoating, the primer does not need puttying, and the coating can be directly used, so that the repairing and recoating performance is good, the technology and quality are not influenced, labors are saved, and the environmental pollution is reduced.
Description
Technical field
The present invention relates to a kind of coating, specifically a kind of based on the coating of urethane resin and melamine resin, be applicable on the exterior glass steel part of electromobile.
Background technology
The Putty of primer base, when carrying out reparation recoat, generally need be beaten and wipe off, and then apply by the exterior glass steel part of electromobile, and therefore not only cost of labor is large, and to being unfavorable for environmental protection.
Summary of the invention
Technical problem to be solved by this invention is to provide the coating of the exterior glass steel part of electromobile that a kind of bonding strength is high, recoat performance is good.
For solving the problems of the technologies described above, the invention provides the coating of the exterior glass steel part of a kind of electromobile, its component and weight percent as follows: urethane resin 40-45%, melamine resin 18-20%, pigment 20-25%, auxiliary agent 3-6%, xylene solvent 8-10%, 150# solvent 2.5-3.5%.
Described auxiliary agent comprises one or more of defoamer, flow agent, adhesion promoter, dispersion agent, anti-settling agent etc.
The preparation method of the coating of the exterior glass steel part of above-mentioned electromobile comprises the steps:
(1) by urethane resin, melamine resin mixing, formation base hybrid resin is stirred;
(2) basic hybrid resin drops into pigment in stirring, and is dropped into by various to defoamer, flow agent, adhesion promoter, dispersion agent, anti-settling agent etc. auxiliary agent by spray method when stirring, and forms paint vehicle;
(3) in paint vehicle, drop into xylene solvent, 150# solvent, stir the coating that namely can be configured to the exterior glass steel part of this electromobile for 3-5 minute.
Technique effect of the present invention: the coating of the electromobile exterior glass steel part of the application has carried out effective adjustment to coating internal chemical structure, molecular structure, the molecule content of coating is between 15000-30000, coating is improved in secondary coating postadhesion power, have stronger bonding strength, and when repairing recoat, primer base is without the need to beating putty coating, this coating can use, thus repair recoat performance good, do not affect technique and quality, both saved and manually again reduced environmental pollution.
