The present invention belongs to special paint for a motor vehicle chassis, which is mainly composed of base materials and additives. The base materials and the additives respectively comprise components and weight percentage: (1), 68.5-111.5% of the base materials; (2), 4.8 to 15.2% of the additives. The present invention has the main advantages that the paint can be firmly attached to a smooth metal surface by simple spray coating operation to form a firm protective layer, and the paint can effectively protect the metal structure of a chassis against corrosion; when a vehicle is operated, the generated vibration and the generated noise can be greatly reduced, and the present invention has a wide application prospect in a motor vehicle production field.

Description

Vehicle chassis paint and preparation method thereof

The invention belongs to a kind of coating, particularly in a kind of tailor-(made) coating of motor-vehicle chassis.

At present, how the tailor-(made) coating of motor-vehicle chassis or pitch glue are from external import, as the U.S. and Korea S.Since import coating price costliness, the environment for use that also is not suitable for China that has.Therefore, development is applicable to that the chassis paint of China's motor vehicle environment for use has been very necessary.

The objective of the invention is actual needs, on the basis of state's like product performances such as analysis and research Korea Spro, U.S., and take into full account the environment for use characteristics of China's motor vehicle, manufacture experimently out a kind of tailor-(made) coating of motor-vehicle chassis from the domestic market, or pitch glue.

Motor-vehicle chassis tailor-(made) coating of the present invention, it mainly is made up of basic material and additive, and it is characterized in that its basic material and additive are formed and weight percent (%) is respectively: (1) basic material is:

Wherein: 120# industrial naptha 23～36%

10# pitch 14～22%

100# pitch 6～12%

Wilkinite 2～3%

Light calcium carbonate 11～18%

325 order mica powders 12～19%

Processing silicon-dioxide 0.5～1.5% (2) additive is:

Wherein: petroleum sodium sulfonate 1.6～2.6%

Succimide (T-154) 0.6～1.6%

Polybutene or polyisobutene 2～8%

Sorbitan monooleate (S-80) 0.1～0.4%

Alkylphenol and ethylene oxide condensate (OP-10) 0.1～0.8%

Polymethacrylate (HV-210) 0.3～1%

The preparation method of polyisobutene (T-603) 0.1～0.8% motor-vehicle chassis tailor-(made) coating of the present invention, its steps in sequence is: 1) binding preheating: 100# pitch is preheated to about 70 ℃; 2) binding enters the reactor stirring and continues heating: the 100# pitch after the preheating is entered in the reactor stir, and continue to be warmed to 70-90 ℃ under normal pressure, add 120# solvent gas and oil and 10# pitch successively; 3) add portions additive: stir in reactor, add the portions additive petroleum sodium sulfonate gradually simultaneously, T-154 and polyisobutene continue to stir 2-6 hour; 4) in closed management, leave standstill after the circulation: above-mentioned material is circulated with toothed gear pump at closing pipe line, and put into jar after lasting 1-2 hour and left standstill 24-72 hour; 5) add solids and portions additive again, and detect physical and chemical index at any time: material enters stirring tank, under normal pressure, stir and add solids wilkinite, lime carbonate, mica powder and silicon-dioxide and additive S-80, OP-10, HV-210 and T-603, detection at any time; 6) pump into closing pipe line and circulate, continue 2-6 hour, detect and adjust physical and chemical index; 7) detect the examination spray, seal in the bucket of packing into after qualified.

Motor-vehicle chassis tailor-(made) coating of the present invention can be securely attached to slick metallic surface through simple spraying operation; form a firm protective layer; and it is not softening under the hot environment; non-scale under the low temperature environment; do not come off after the gravel impact; be sprayed on the motor-vehicle chassis surface and can protect the metal construction on chassis not weather effectively, and can reduce vibrations and the noise that produces in the vehicle operating significantly, have a wide range of applications at the motor vehicle production field.

The present invention has the motor-vehicle chassis tailor-(made) coating to have good shockproof effect, and preservative property and adhesivity are better, excellent storage stability, and low temperature is embrittlement not, and anti-impact force is strong, and sprayability is good, and covering of the fan is even, is suitable for the coating of automobile chassis.Through Chinese Academy of Sciences's acoustics the unit of grade detect, its performance is better than U.S.'s like product certainly, its quality index is listed table 1 in. sequence number project quality index Test method 1 color black estimate 2 smells not to be had obvious peculiar smell sense of smell 3 viscosity (20 ℃) 8-30 pressure viscosimeter second 4 flowabilities and measures the anti-peeling of the 5 cold conditions bumps qualified SAE J-6706 of adhesive force less than 2 inches (50.8mm) chis and do not come off; Bubbling not, non-scale are estimated 30 minutes tack-free hands of 7 drying property and are touched all not stratified qualified GB XXXX of the range estimation qualified ASTMB-11711 sound insulation value of 10 corrosion resistances that do not precipitate in even spray 9 bin stabilities 90 days of 8 technologies examination spray state covering of the fan
