The component A comprises trifluoro-FEVE resin, hydroxyl acrylic resin, diluents, dispersing agents, titanium dioxide, heat-reflecting pigment, thixotropic agents, leveling agents, anti-ultraviolet absorbents, adhesion promoters and defoaming agents; the component B is an isocyanate curing agent. The heat-reflecting fluorinated polyurethane finish paint has the advantages that the heat-reflecting fluorinated polyurethane finish paint can be brushed in diversified modes just like common coatings and can be conveniently and quickly constructed; the hydroxyl acrylic resin and the trifluoro-FEVE resin are mixed with each other in a formula and are supplemented with other auxiliaries, accordingly, the excellent weather resistance of films can be kept, and the films with the heat-reflecting fluorinated polyurethane finish paint are high in gloss, bright in color and good in adhesion just like films with conventional polyurethane coatings; the heat-reflecting pigment which is of a unique structure is used with the high-quality titanium dioxide in the formula, accordingly, the heat-reflecting fluorinated polyurethane finish paint is extremely high in sunlight reflectivity and applicable to diversified fields of large petroleum storage tanks, outdoor buildings, special tanks and the like, and obvious heat-insulation effects can be realized.
Description
Technical field
The present invention relates to the coating manufacturing technology in chemical industrial field, be specifically related to a kind of heat reflection fluorochemical urethane finish paint.
Background technology
Heat reflection protective system is a kind of functional paint be mixed with by polymer organic resin interpolation special type filler.The protection of its existing general coating and decoration functions, having again reflected sunlight, intercept the characteristic of thermal energy transfer, is the new special coating integrating protection against corrosion and heat insulation and heat control.
The effect of heat insulation of heat reflection protective system, obtains the reflection of sunlight mainly through the particular fillers added in formula.Polymer organic resin is owing to having very high sunlight penetration coefficient, so only play the effect of film forming in formula, to heat reflection not contribution, but, not only the macromolecule resin of weathering resistance difference does not help heat reflection, the insulative effectiveness of paint film also can be reduced.Out of doors in environment, use the paint film of the macromolecule resin of weathering resistance difference, under the irradiation of sunlight, xanthochromia, efflorescence occur, the L value of paint film is reduced, in addition, the efflorescence due to surface causes paint film more easily to be polluted, and contaminant accumulation is embedded in coating surface, low-L value falls further, and L value declines, the sunlight reflectivity of paint film will decline, and makes the thermal insulation of painting be deteriorated thus.
In view of this, special proposition the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides one to have excellent weather resistance, and also has the heat reflection fluorochemical urethane finish paint of the features such as conventional polyurethanes coating gloss is high, bright-colored, sticking power is good simultaneously.
