Abstract

The invention relates to a novel mineral reflective thermal insulation coating for architecture and a preparation method thereof. The coating comprises, by weight, 0.1-0.6% of a thickener, 0.2-1.2% of an antifoaming agent, 0.1-0.5% of a dispersing agent, 0.5-1.0% of a stabilizer, 6.0-20.0% of functional pigments, 5.0-27.0% of fillers, 4.0-10.0% of a modified emulsion with a concentration of 46-50wt%, 15.0-23.0% of potassium silicate with a concentration of 28-32wt%, 1.0-5.0% of a water repellent agent, 6.0-10.0% of ceramic microbeads, 0-1.5% of a rheological agent and the balance water. According to the coating and the preparation method thereof, defects of latex type reflective thermal insulation coatings are overcome, national standards are accorded with, and the advantages of being energy-saving, economical, environment-friendly, low-carbon, flame retardant, high temperature resistant, good anti-aging and anti-contamination performances and the like of inorganic coatings are maintained.

Description

Technical field: [0001] The present invention relates to a kind of paint and its preparation method, more specifically, relates to a new type of mineral reflective heat insulation paint for building and its preparation method. Background technique: [0002] With the introduction of various national building energy-saving policies, the public security department has increased the fire protection requirements for building external insulation materials. Traditional building energy-saving materials such as thermal insulation mortar and EPS external insulation systems are becoming more and more disadvantageous due to flammability, cracking, leakage, and falling off. Obviously, and the construction is cumbersome, the cost is high, and it is not suitable for the construction of special-shaped complex structures. A large number of plate gaps form thermal bridges, which makes it difficult to further improve the energy-saving effect of the system. [0003] As a new type of green and ...
