Building coating and preparation process thereof

Abstract

The invention discloses building coating and a preparation process thereof. The building coating comprises the following components in percentage by weight: 60%-80% of water-soluble urea formaldehyde resin, titanium dioxide and water, 5%-8% of polyvinyl alcohol, 2%-8% of ethylene glycol, 2%-5% of plasticizer, 1%-3% of emulsifier, 1%-6% of water repellent agent, 6% of dimethyl phthalate, 11% of triphenyl methane crylactone and 2% of vanadium oxide. The preparation process of the building coating comprises the following steps of: mixing the water-soluble urea formaldehyde resin, the titanium dioxide, the water, the polyvinyl alcohol, the ethylene glycol, the plasticizer, the emulsifier, the dimethyl phthalate, the triphenyl methane crylactone and the vanadium oxide in proportion; stirring and heating up the mixture to 95 DEG C, grinding the mixture for 45 minutes at the grinding speed of 500 revolutions / minute; cooling the mixture to 50 DEG C, adding the water repellent agent in the proportion for stirring and reacting for 20 minutes to obtain the finished product. The building coating has the following advantages of realizing reversible conversion between heat absorption in winter and heat insulation in summer, relieving the environmental pollution and the greenhouse effect, being high in water resistance effect and high in anti-pollution effect.

Description

technical field [0001] The invention relates to an architectural coating and a preparation process thereof. Background technique [0002] At present, most of the middle and low-grade architectural coatings on the market have unsatisfactory water resistance and anti-fouling properties. If the water resistance and anti-fouling properties of the entire coating are to be improved to an ideal level, it is often necessary to increase the high cost; and common coatings Also affected by the ambient temperature, the temperature of the building surface rises in summer, which causes the temperature of the building coating to rise, and in winter the building coating will decrease accordingly, so it cannot be applied to buildings with seasonal changes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an architectural coating with high water resistance and anti-pollution effect, which can realize reversible conversion of heat a...

If the water resistance and anti-fouling properties of the entire coating are to be improved to an ideal level, it is often necessary to increase the high cost; and common coatings It is also affected by the ambient temperature. In summer, the temperature of the building surface rises, which causes the temperature of the building coating to rise. In winter, the building coating will decrease accordingly. It cannot be applied to buildings with seasonal changes.
