Description
Solar heat shielding paint of the present invention.It is applicable to oceanic tectonic things such as being sprayed on ship deck, offshore oil tank, offshore platform; The ground structure of round shape or spherical oil tank etc.; Buildingss such as dwelling house, mansion, warehouse or gymnasium; On the outdoor mobile objects such as automobile, tank wagon, freezing and refrigeration freight container and on the shell of household electronic products such as refrigerator.It mainly acts on is to prevent to rise because of the sunlight direct projection causes internal temperature, improves cold air, refrigerated effect, reaches purpose of saving the energy and the volatilization that prevents compositions such as oil, methyl alcohol.
Room temperature in the buildings can raise because of Exposure to Sunlight, in the past, has spent the air-conditioning expense of great number in order to reduce room temperature, in order to save its expense, people to oil tanker, natural gas carrier vessel, the shell of oil tank etc. sprays covering on the bank, to suppress the evaporation of internal component.And wish very much to improve cooling, the refrigerating effect of equipment such as the cooling of oil tank and household electrical appliance, using the coating of white pigments such as containing titanium oxide or coloured dyestuff widely for this reason, but these coating are except that white, in case its solar heat screening effect that dyes will obviously go down.
In addition, being used for the coating of appearances such as buildings ridge, oil tank as everybody knows, mainly is the aluminum paint that contains the flakey aluminium powder.Its color has limitation, and is also undesirable aspect weather resistance.It is poor also to exist wearability, is not suitable for the shortcoming in walking place.
In order to address these problems, proposed to use the heat reflection enamel paint that contains antimonous oxide, epoxidation antimony, basic metal epoxidation chlorine etc. on the patent publication " patent disclosure clear and 56-109257 number ", but it is because of it contains heavy metal, so not fully up to expectations aspect environmental protection.
" patent disclosure clear and 55-33828 number ", " patent disclosure clear and 55-120669 number ", " patent disclosure clear and 55-74862 number " wait introduced on the publication use contain particle diameter as the latex coating of the glass granules of 20-350 μ, contain the coating of synthetic silicon grain white below particle diameter 300 μ, or contain the making method that particle diameter is the metal sheet that sprays of the coating of the beads of 5-300 μ.These coating have good solar heat screening effect in the early stage, but it exists appearance uneven, and resistance to crocking is poor, and contaminated back solar heat screening effect significantly descends the degradation shortcoming.
Introduce the strong resin of weathering resistance on " patent disclosure is put down into 1-263163 number " communique, also introduced a kind of novel solar heat shielding paint simultaneously.It is characterized in that particle diameter below 50 μ Si or Si and Al, Fe, Mg, Mn, Ni, Ti, Cr, Ca in alloy blending more than any cover pigment for solar heat, these one or more alloy occupies 2-50% in the solids component of coating weight.
