Abstract

The invention discloses an environment-friendly heat insulation building coating in the field of coatings. The coating comprises the following components in parts by weight: 20-25 parts of styrene-acrylic emulsion, 1-5 parts of benzyl alcohol, 1-5 parts of ethylene glycol, 1-5 parts of hydroxyethyl cellulose, 1-5 parts of tributyl phosphate, 1-3 parts of sodium polyphosphate, 10-20 parts of nanometer titanium dioxide, 5-15 parts of nanometer aluminium silicate, 5-10 parts of chitosan, 10-15 parts of hollow glass beads, 15-25 parts of paraffin microcapsules and 10-25 parts of distilled water. The environment-friendly heat insulation building coating disclosed by the invention has the beneficial effects that the basic performances, such as drying time, water resistance, alkali resistance, scrubbing resistance, adhesive force and the like of the coating reach the national standard; the thermal insulation effect is good, the maximum temperature difference with a blank sample is 18 DEG C, the average temperature difference is 15 DEG C, and the two substances such as the paraffin microcapsules and the hollow glass beads have a synergetic effect, so that the thermal insulation effect of the coating is enhanced, and the antibacterial effect is good.

Description

Technical field [0001] The invention is the field of coating and involves a kind of environmental protection insulation building coatings. Background technique [0002] Energy -saving and environmental protection is currently the goal of scientists in all countries in the world. Paraffects are very wide -looking phase -changing materials, which have many advantages, but at the same time, there are disadvantages such as large changes in the volume of solid fluid phase change, leakage, and heat transfer.Paraffinization microcapsule can solve the above problems well in recent years.The application of paraffin micro -capsule in building coatings has significant significance. It can absorb the heat of solar radiation, and keep the indoor temperature unchanged without consuming electrical energy to achieve the effect of heat insulation. [0003] In order to save energy consumption, it should be the greatest thermal insulation effect of thermal insulation coating. In this waycoating.Whe...
