Description
Technical field
The present invention relates to a kind of camouflage color coated technique being applied to offroad vehicle gas extraction system, protect for offroad vehicle gas extraction system.
Background technology
Can improve the camouflage protective capacities of tactical vehicle and survival ability be directly affect army " draw and draw, get continuously, hide firmly " and can logistics accomplish the important step of " adequate logistic support ".In order to meet and promote the pattern paint camouflage performance of tactics offroad vehicles gas extraction system, ensure in prolonged application, refractory coating ensures that color is homogeneous and corrosion-resistantly reach requirement, meet the life requirement that product uses.Need the camouflage color coated technique adopting offroad vehicle gas extraction system.
At present conventional heat resistant finish camouflage protective action and protection period undesirable.Do not reach product instructions for use.The color of general heat proof material is single, is unsuitable for camouflage painting application.The coating process of traditional vehicle exhaust system is generally: clean-application tradition heat-resisting paint-drying.Spray traditional heat-resisting paint or the traditional antirust coat of application, after heat resistant test, variable color is serious, does not reach the various voltinism requirement of pattern-painting color, poor corrosion resistance (salt spray test is less than 100h); Cause exhaust system assembly local corrosion perforated phenomenon serious, cause camouflage color variable color to lose efficacy.According to relevant international standard requirement, the heat-resisting rear color corrosion resistance of offroad vehicle exhaust system assembly requires very high, therefore it is also proposed higher requirement to the heat-resisting rear corrosion resistance of this system.After 500 DEG C of heat resistant tests, secondary salt spray test should reach more than 240 hours.After test, paint film increases without obvious variable color, efflorescence, loss of gloss or gloss, mechanical performance is without significant change and then ensure the camouflage performance of camouflage color.
Summary of the invention
The object of the present invention is to provide a kind of camouflage color coated technique being applied to offroad vehicle gas extraction system; it is in order to improve the coating quality level of domestic offroad vehicle; eliminate already present coating quality issues; reduce the quality gap of same import offroad vehicle; improve the adhesion strength more than 60% of protective finish in metal surface, there is the effect that excellent heat-resisting and corrosion-resistant and environment merges.
Technical scheme of the present invention is achieved in that a kind of camouflage color coated technique being applied to offroad vehicle gas extraction system, it is characterized in that heat-resisting coating with pattern painting is made up of following raw material by weight: the nano ceramics cenosphere of 1 ~ 5 part, the modified poly ester epoxy organosilicon binding agent of 20 ~ 30 parts, 20 ~ 30 parts of high-temperature resisting pigments, the dimethylbenzene that retarder thinner is 30 ~ 40 parts and acetone double solvents.
Described binding agent comprises modified poly ester, epoxy silicone resin obtains by 2:3.
Described retarder thinner includes dimethylbenzene, acetone makes double solvents by 3:2.
Coated technique is as follows: workpiece bead-compressed air cleaning-antirust treatment-application ground floor coating-drying-time camouflage color covers-application second layer camouflage painting-under cover-drying-secondary camouflage color covers-application third layer camouflage color-under cover-dry-three camouflage colors cover-application the 4th layer of camouflage painting-drying.
The condition of cure of described refractory coating is temperature is heat preservation solidification 24h under the condition of room temperature 20-30 DEG C; The best is 80 DEG C of insulations 20 minutes.
Good effect of the present invention is to improve the adhesion strength of heat-resisting protective coating in metal surface, has excellent heat-resisting and decay resistance.
