Abstract

The invention discloses an external wall thermal insulation coating as well as a preparation method and application thereof, and belongs to the field of external wall coatings. The external wall thermal insulation coating comprises the following components by weight: 15-30 parts of water; 0.2-0.5 parts of hydroxyethyl cellulose; 1-1.5 parts of ethylene glycol; 30-40 parts of inorganic resin; 8-15parts of an acrylic emulsion; 0.3-0.5 parts of lauryl sodium sulfate; 3-6 parts of an inorganic water repellent; 6-15 parts of pigment and filler; 23-38 parts of a thermal insulation filler; and 0.1-0.2 parts of a multifunctional auxiliary agent. The coating disclosed by the invention can be directly applied to a cement mortar wall reinforced by seal primer, and has the advantages of good thermalinsulation property, high fireproof grade, good hydrophobicity and good comprehensive performance.

Description

technical field [0001] This application relates to the technical field of exterior wall thermal insulation coatings, more specifically, it relates to an exterior wall thermal insulation coating, a preparation method and its application. Background technique [0002] In response to the national building energy conservation and environmental protection policy, dry-hanging external wall insulation boards are commonly used in the market. However, with the extension of use time, the insulation boards are prone to cracking, water seepage, falling off and hurting people. Later, the market switched to the combination of external wall thermal insulation mortar and internal thermal insulation desulfurized gypsum to solve the disadvantage that the thermal insulation board is easy to fall off and hurt people. Although this method can simplify the construction, it is necessary to continue to construct anti-crack putty, Sealing primers and exterior wall weather-resistant coatings not only...
