Abstract

The present invention relates to a low heat conductivity metallic luster paint and its preparation method. In its composition the pigment with specular sheet structure and tinted filling material with porous structure are contained. Said building paint has the advantages of low thermal conductivity, good heat-insulating effect and good water solubility. Its preparation method includes the following steps: the wetting agent, dispersing agent, water, pigment with specular sheet structure and filling material with porous structure are fully stirred and wetted to obtain component A; at the same time the silicon acrylic emulsion, thickening agent and film-forming adjuvant are stirred and mixed uniformly to obtain component B, then the component A and component B are stirred uniformly, the defoaming agent is added, stirred for 0.5 hr., filtered and filled so as to obtain the invented product.

Description

technical field [0001] The invention relates to a metal luster paint with low heat conduction, more specifically to a water-soluble paint containing specular flaky structure pigments and light-colored fillers with a porous structure and having low heat conduction heat preservation and metal luster decoration effects. [0002] The invention also relates to a method for preparing the coating. Background technique [0003] Building materials will cause a certain amount of heat exchange loss inside and outside the building through heat conduction. The thermal conductivity of wall materials increases with the rise of temperature, and the effect of preventing solar radiation is minimal. According to the inspection of Shanghai Tongji Construction Engineering Quality Inspection Station, the wall The thermal conductivity of the bulk material is generally around 0.5-1w / mk. Current common methods to reduce heat exchange losses inside and outside buildings include: [0004] 1) Increas...
