Abstract

The invention relates to external wall flexible putty powder with a light reflection function and a preparation method thereof. The putty powder is prepared by mixing the following components in partsby mass: 20.0-35.0 parts of white cement, 10.0-50.0 parts of hollow glass beads, 5.0-25.0 parts of titanium dioxide, 5.0-12.0 parts of silicon dioxide powder, 0.1-60.0 parts of ground calcium carbonate powder, 3.0-7.0 parts of redispersible latex powder, 0.3-0.5 part of cellulose ether, 0.3-1.0 part of bentonite, 2.0-7.0 parts of metakaolin and 0.01-0.2 part of starch ether. The putty powder disclosed by the invention is outer wall flexible putty with relatively high ultraviolet reflection, sunlight reflection ratio, near-infrared reflection ratio and hemispherical reflectivity.

Description

technical field [0001] The invention relates to a flexible putty for exterior walls, in particular to a flexible putty powder for exterior walls with light reflection function and a preparation method thereof. Background technique [0002] The exterior wall putty is suitable for exterior wall decoration projects and is an important part of the entire coating system, providing good base level flatness and bonding strength for the entire decorative layer. Among them, the flexible putty for exterior walls has excellent flexibility, and is widely used in places with high requirements for flexibility of the base layer, such as exterior wall insulation and decoration projects. [0003] In recent years, there are serious fire safety hazards and hidden dangers of falling off and hurting people due to the dry-hanging insulation systems (such as rock wool insulation and decorative composite boards, XPS extruded boards, polystyrene particle boards, etc.) commonly used in external wall ...
