Abstract

An insulating paint for vehicle is prepared from acrylic resin, diluent, disperser, defoaming agent, anti-deposition agent, pigment, filler, drying agent, UV resistant, and porous ceramic microbeads for reflecting sunlight.

Description

Heat insulation vehicle paint and production technique thereof

Technical field:

The present invention relates to the technical field of coating, specifically a kind of can mainly be thermal insulating coating and the production technique thereof that is used for vehicle.

Background technology:

At present, product about heat-insulating and energy-saving commonly used mostly is the outer insulating product of exterior wall, this product is to utilize the low heat transfer coefficient of thermal baffle to realize low-yield loss, this series products can only be passive minimizing energy height between transmission, because in atmosphere, energy is that carrier transmits by light wave, when solar irradiation strong, the too high then not significantly effect of free air temperature, this series products all can increase thickness in addition, comparatively strict requirement is also arranged in construction, time-consuming bothersome, also be not used in the heat insulation coating of vehicle in the prior art.

Summary of the invention:

The object of the present invention is to provide a kind of heat insulation vehicle paint and production technique thereof, the radiation of antireflection part sunlight effectively of this heat insulation vehicle paint, thus reduce the heat energy that the coated article body receives.

To achieve these goals, technical scheme of the present invention is heat insulation vehicle paint, it is characterized in that: the weight percentages of components of described heat insulation vehicle paint is acrylic resin 40-45%, thinner 8-12%, dispersion agent 0.1-0.5%, defoamer 0.05-0.3%, anti-settling agent 0.2-0.8%, pigment 20-25%, filler 6-8%, siccative 0.05-0.1%, ultraviolet screener 0.05-0.2%, porous ceramics microballon 15-20%.

The production technique of heat insulation vehicle paint, it is characterized in that: with weight percent is that acrylic resin 40-45%, thinner 8-12%, dispersion agent 0.1-0.5%, defoamer 0.05-0.3% are fed into the low speed dispersion that the production container carried out 15 minutes, and then pigment 20-25%, filler 6-8% add produced the high speed dispersion that container carried out 40 minutes, through filtering greater than 150 purpose filtering nets, adding siccative 0.05-0.1%, ultraviolet screener 0.05-0.2%, porous ceramics microballon 15-20% again, to carry out stirring at low speed even, and packing is produced at last.

The present invention is owing to contain the porous ceramics microballon in the component of coating, reflected sunlight effectively, through testing when solar irradiation is mapped on the coating, there is the sun light wave about 85% to be reflected, and general common coating can only reflect 13%, sun light wave, promptly reduced by 72% sunlight absorption rate than common coating, thereby greatly reduced the temperature of coated article, this thermal insulating coating especially is suitable as the thermal insulating coating of vehicle, it is very easy to construct, save time and save trouble, the temperature of coated article can not raise with the sunlight acute irradiation, has heat insulation and energy-conserving action, simultaneously can save a large amount of energy, meet the long-range energy strategy plan of country.Below be noon one day 11:30 to the actual test of the relevant position of 911 tunnel (bilayer) motorbus temperature, weather condition: fine, cloudy, test sample car: adopt two No. 911 double deck buses of the same type (wherein scribbles this automobile-used thermal insulating coating spraying car load roof)

Test condition: close the doors and windows 11:30 at noon thermometric simultaneously

Test result:

The position	Scribble the thermal insulating coating vehicle	Do not spray the thermal insulating coating vehicle	The temperature difference
