Abstract

The invention relates to a compound-type metal roof thermal-insulation waterproof coating and a preparing method thereof. The compound-type metal roof thermal-insulation waterproof coating is composed of a surface layer coating and a base layer coating. The surface layer coating is prepared from water, dispersing agents, antifoaming agents, pigment, hollow glass beads, inorganic-thixotropy thickening agents, inorganic filler, silicone-modification acrylic emulsion, acrylic emulsion, film forming assistants, pH value regulation agents, thickening agents and antifreeze agents; the base layer coating is prepared from water, dispersing agents, antifoaming agents, pigment, heat-conducting functional filler, inorganic-thixotropy thickening agents, inorganic filler, acrylic emulsion, pH value regulation agents, thickening agents and antifreeze agents. Compared with the prior art, the problems that bonding of a present waterproof material and a metal base material is not firm, aging is prone to occurrence and the service life is limited are solved, and the compound-type metal roof thermal-insulation waterproof coating has the advantage of integrating water proofing, protection, rust protection and thermal insulation.

Description

technical field [0001] The invention relates to a heat-insulating and waterproof coating and a preparation method thereof, in particular to a composite metal roof heat-insulating and waterproof coating and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy, steel structure buildings are widely used in large buildings such as workshops, logistics warehouses, and sports venues due to their advantages such as light weight, high strength, high degree of factory pre-installation, convenient construction, and significant comprehensive economic benefits. superior. [0003] As an important part of buildings that cannot be ignored, steel structure is of great significance to effectively insulate and waterproof steel structure metal roofs under the environment where the whole society advocates energy conservation and emission reduction. The material characteristics of the steel structure metal roof itself and the causes of co...
