Abstract

The invention discloses an external wall building coating with reflective thermal insulation and heat preservation and insulation effects and a preparation method thereof. By using a waterborne sand dyeing method, the surface of quartz sand is uniformly coated with a reflective thermal insulation pigment; and meanwhile, glass beads are added to finally prepare a thick coating with double effects of reflective thermal insulation and heat preservation and insulation. The external wall building coating with the reflective thermal insulation and heat preservation and insulation effects, disclosedby the invention, has the advantages that the thermal insulation effect is outstanding; the temperature difference between inside and outside can reach 15 degrees centigrade or above; by using the waterborne sand dyeing method, energy is saved, the environment is protected, and the destructive effect of mining color sand raw materials on the environment is reduced; and as the external wall building coating with the reflective thermal insulation and heat preservation and insulation effects is integrally molded, the construction is convenient, the deadweight is lower, and potential safety hazards do not exist.

Description

technical field [0001] The invention belongs to the field of architectural coatings, and in particular relates to an exterior wall architectural coating with reflective heat insulation and thermal insulation functions and a preparation method thereof. Background technique [0002] Various existing building insulation systems have more or less disadvantages. [0003] 1. The insulation system based on various types of insulation boards (such as EPS, XPS, asbestos boards, etc.) has defects such as non-environmental protection, complicated construction, fire hazards, and high-altitude safety hazards. [0004] 2. The thermal insulation system with thick thermal insulation mortar as the core has problems such as complicated construction and poor thermal insulation effect. [0005] 3. Thin-layer thermal insulation system represented by latex paint for reflective heat insulation exterior wall. This type of thermal insulation system is only used in the south. It has the ability to r...
