Abstract
The invention discloses a preparation method for a violet pigment capable of reflecting infrared ray, and a heat-isolating paint. The preparation method comprises the following steps of: weighing aluminium oxide, cobaltous oxide, magnesium oxide, titanium dioxide and zinc oxide in a certain mass ratio, ball-milling and uniformly mixing; calcining the grinded mixture for 2-4 hours at 850-950 DEG C, cooling the mixture, and then mixing the mixture with a certain amount of ferric oxide, then ball-milling into a powder, and uniformly mixing the powder with a common alkyd varnish in a weight ratio of 1:9, wherein the obtained heat-isolating paint is capable of obviously reflecting the heat of infrared ray in the sunlight. In addition, the method disclosed by the invention is less in equipment investment, simple in preparation process and easy to operate, thus being suitable for large-scale industrialized production.
Description
Technical field
The present invention relates to a kind of preparation method with violet pigment of reflected infrared function, and with the heat insulation paint of this pigment preparation.
Background technology
The automobile case that employing contains the paint spay-coating of dark pigment comparatively bears dirty, but dark cars shell easy absorbing heat under sunlight makes vehicle interior temperature be easy to raise and cause sense of discomfort to the people.Heat in the sunlight mainly transmits by infrared rays; if adopt the common dark pigment in the alternative automobile case coating of the dark pigment with reflected infrared function; then can be so that the temperature in the car be unlikely to raise too fast; especially in summer; can greatly alleviate the load of automative air conditioning, thereby reach the purpose of energy-saving and emission-reduction and protection of the environment.At present existing a small amount of infrared reflecting paint is developed out, just reported the black that contains transition metal or rare earth element, brown, blueness or veridian such as US Patent No. 6416868, US20090223414, US6221147, US6541112, but there are the defectives such as complicated process of preparation or its properties of infrared reflection be good not in these pigment.So far, find that not yet the research that relevant method preparation by doping-toning has the heat insulation pigment of purple of reflected infrared function is seen in report.
Summary of the invention
The purpose of this invention is to provide a kind of preparation method with violet pigment of reflected infrared function, and this violet pigment added to make the thermal insulating coating product in the coating, the infrared rays heat in can reflected sunlight alleviates the automative air conditioning load.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
But a kind of violet pigment preparation method of reflected infrared is characterized in that, may further comprise the steps:
(1) matrix material of the following component of weighing in mass ratio: aluminium sesquioxide a: cobaltous oxide a: magnesium oxide: titanium dioxide: one zinc oxide=100:30-40:15-25:3-5:2-4;
(2) the raw material dry ball milling after the above-mentioned weighing is mixed;
(3) mixture behind the dry ball milling was calcined 2-4 hour under 850-950 ℃, after its cooling, namely obtained crude product;
(4) with this crude product and ferric oxide in mass ratio after the 100:2-5 weighing again dry ball milling be mixed into powder, namely obtain having the violet pigment of reflected infrared function.
A kind of heat insulation paint is characterized in that, adopts aforementioned violet pigment with reflected infrared function and alkyd varnish to obtain by weight stirring after 1:9 mixes.
The present invention compares with the prior art of preparation infrared reflecting paint, have the following advantages: the violet pigment of the present invention preparation has good infrared reflection performance (reflectivity TSR is 61%-70% at total sunshine of wavelength 400-2500nm), can be used for it is added to making the thermal insulating coating product in the coating; In addition, but the violet pigment production unit of the reflected infrared of the present invention's preparation is mainly ball mill and firing electric furnace, and equipment investment is few, preparation technology is simple and easy handling, so be fit to large-scale industrial production.
