Problems solved by technology

[0002] Today, with the diversification of the construction industry, "building exterior walls" are no longer a single form. There are light and soft thermal insulation walls, as well as heavy and rigid walls. Due to major changes in the base layer, in fact There are considerable differences in the application conditions of exterior wall putty in construction, and the original practices and standards obviously cannot meet the needs of development

Abstract

The invention relates to putty for an exterior wall of a building and particularly relates to multifunctional thermal-insulation putty and an application method thereof. The multifunctional thermal-insulation putty comprises the following components: cement, quartz powder, quartz sand, glass microbeads, gray calcium, heavy calcium carbonate, Wacker glue powder, Ruitai cellulose, ultra-short fiber, wood fiber and starch ether. The multifunctional thermal-insulation putty has small density, dry apparent density of less than 500Kg/m<3>, large coating area, small thermal conductivity coefficient, high bonding strength, strong adhesion force with a substrate and a rendering coat and good self-cracking resistance; the comprehensive cost is decreased and honeycomb cracks generated due to temperature differences among the thermal-insulation layers are reduced and the multifunctional thermal-insulation putty is simple in proportioning and is convenient to construct.

Description

Technical field [0001] The invention relates to a putty for building exterior walls, in particular to a multifunctional thermal insulation putty and a use method thereof. Background technique [0002] With the diversification of the construction industry today, "building exterior walls" are no longer a single form. There are light and soft thermal insulation walls and heavy and rigid walls. Due to major changes in the base layer, in fact The application conditions of exterior wall putty in buildings are quite different, and the original practices and standards obviously cannot meet the needs of development. The Ministry of Construction issued the industry standard of "Putty for Building Exterior Walls" on February 12, 2004 to standardize its production and use. In the past two years, many scientific research units and manufacturers have developed a variety of formulas. High-quality putty with waterproof, crack resistance and high bonding strength. In response to the "Regulation...
