So that the more and more important change of the anti-corrosion of automobile chassis, once vehicle chassis component loosens will be directly connected to the peace of vehicle and car owner
Entirely.Antirust most conventional processing method in chassis is rust prevention by applying liquid material paint, and the main product of current antirust paint is oily antirust varniss and water
Property antirust paint, oily antirust varniss because its not enough environmental protection, toxicity it is larger；Although aqueous antirust paint disclosure satisfy that requirement in environmental protection,
But its protection cycle is shorter, and using being restricted, how to obtain not only long-acting but also environmentally friendly antirusting paint is that industry is endeavoured at present
The direction of research.
Thermoset epoxy powdery paints because of its good feature of environmental protection and excellent metal surface adhesive force, in automotive chassis components
Have a good application prospect in antirust, but epoxide powder coating is present that solidification temperature is high, construction equipment is had high demands, film layer
The defects such as poor flatness, need to do which further study on the modification, to improve its combination property.《A kind of epoxy radicals acrylic acid
The preparation research of resin low-temperature setting transparent powder paint》One text is compounded with the acrylic resin of different epoxide equivalents, with bisphenol-A
Epoxy polyester obtains the powdery paints solidified at 150-160 DEG C as curing accelerator, although this coating solidification temperature
Degree is reduced, but its mechanical property is slightly worse, and hardening time is longer, and the flatness of film layer also has much room for improvement, and needs to coordinate
Priming paint is used, and in the foundry goods application of chassis also needs further modification..
The content of the invention

Sour methyl ester microsphere.
A kind of preparation of described damping vibration attenuation expediting setting type composite epoxy antirust powdery paints for automobile chassis
Method is：By each raw material according to batch mixing 40-50min in proportioning input high-speed mixer, material input is extruded after terminating by batch mixing
In machine, the melting extrusion tabletting under the conditions of 98-104 DEG C, after sheet material cooling, Jing is crushed and screened, and control product cut size is in 80-200
Mesh, obtains final product.
The present invention is compounded as resin base using epoxy resin E-20, bisphenol-A epoxy resin, epoxy acrylic resin
Body, obtains the composite resin coating with excellent mechanical performances and film-formation result, and the compatibility is good between each resin material, really
Solidification effect is protected, after which is compounded with hindered phenol, asbestos wool so that coating has good damping capacity, and chassis material is had
The protected effect of bumper and absorbing shock, the active group that the hyperbranched polyethyleneimine of addition contains can be effectively promoted resin system
The performance of solidification, curing rate and film layer is improved, the aluminium triphosphate/poly-methyl methacrylate for adding in addition
