Abstract

Polymer microsphere thermal insulation dry powder paint is formed by raw material with following parts by weight of 20-40 water glass powder, 8-15 pore closed expansive perlite, 3-15 hollow glass or ceramic micro-bead, 10-30 polymer phase-change microsphere, 2-5 hollow fiber, 3-5 sodium fluosilicate, 5-10 emulsion powder and 5-10 water-proof anti-permeability addition agent, which shares the common characteristics of thermal resistance type and thermal capacity type materials, and has prominent weatherability and extremely excellent strain resistance. Hollow fiber provides excellent thermal insulation property, and largely increases the properties of pull-resistance, cracking resistance and breaking resistance at large amplitude. An excellent barrier layer is formed through the mutual gradation of hollow glass or ceramic micro-bead, hollow fiber and polymer microsphere and the like according to particle size, thereby largely increasing thermal insulating property. Dry powder supply is employed, which largely reduce transportation cost and storage cost, and is convenient for storing and transporting and construction.

Description

technical field [0001] The invention relates to an interior and exterior wall coating for architectural decoration, in particular to a polymer microsphere thermal insulation dry powder coating. Background technique [0002] In recent years, the thermal insulation and energy saving of buildings has attracted more and more attention. A large number of excellent thermal insulation products have emerged, most of which are mortar products. There are few coating products with excellent thermal insulation performance, low cost and wide application. . Chinese Patent Publication No.: 101108930A, Publication Date: January 23, 2008, the title of the invention is "A Water-Based Thermal Insulation Coating and Production Method", which proposes the use of elastic acrylic modified emulsion, epoxy resin, ethylene glycol, hollow It is formulated with glass microspheres, functional fillers, kaolin, talcum powder and other additives and thermal insulation coatings. It uses the heat reflectio...
