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 motor-vehicle chassis tailor-(made) coating or pitch glue are from external import, as the U.S. and Korea S etc.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 is 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 motor-vehicle chassis tailor-(made) coating 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, it is characterized in that its basic material and components of additives and weight percent thereof are respectively:

(1) basic material is: 68.5-111.5%

Wherein: 120# solvent gas and oil 23-36%

10# pitch 14-22%

100# pitch 6-12%

Wilkinite 2-3%

Light calcium carbonate 11-18%

325 order mica powder 12-19%

Processing silicon-dioxide 0.5-1.5%

(2) additive is: 4.8-15.2%

Wherein: petroleum sodium sulfonate 1.6-2.6%

T-154 0.6-1.6％

Polybutene or polyisobutene 2-8%

S-80 0.1-0.4％

OP-10 0.1-0.8％

HV-210 0.3-1％

T-603 0.1-0.8％

The preparation method of 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 closing pipe line, 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, stir under normal pressure and add solids wilkinite, lime carbonate, mica powder and silicon-dioxide and additive S-80, OP-10, HV-210 and T-603 detect 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, in the bucket of packing into after qualified and sealing.

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.

Motor-vehicle chassis tailor-(made) coating of the present invention has 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 applicable to 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 is estimated 2 smells not to be had obvious peculiar smell sense of smell 3 viscosity (20 ℃) 8-30 pressure viscosity second agent 4 flowabilities and measures the qualified SAE J-670 of 5 cold conditions bumps sticking power less than 2 inches (50.8mm) chis
