Problems solved by technology

However, the existing flexible facing bricks lack thermal insulation fillers in composition, and in the production method, polymer emulsion and mud powder are directly mixed at high speed, which can easily cause emulsion breakage and seriously affect the mechanical properties of the final product.
If the resin and mud powder are directly blended, it is difficult for the inorganic material to disperse evenly in the high-viscosity resin

Abstract

The invention discloses a flexible heat-preserving tapestry brick and a preparation method of the flexible heat-preserving tapestry brick. The raw material of the brick is sizing agent or dry power formed by evenly mixing mud powder, a hollow filler, crylic acid monomers, a cross-linking agent, reinforced fibers, a solvent, an initiator and a fire retardant according to a certain proportion. The preparation method comprises the following steps of: forming in a mould in a heating way, drawing, drying, trimming and the like to obtain the flexible tapestry brick with the functions of heat preservation and flame retardance. The flexible heat-preserving tapestry brick has the characteristics of being flexible, heat-preserving, water-resistant, fire-resistant, anti-stain, anti-aging, scrubbing-resistant, low in specific gravity, simple in production process, low in cost and the like, thereby being widely applicable to the decoration indoors and outdoors.

Description

technical field [0001] The invention relates to the field of building thermal insulation and decoration materials, in particular to a flame-retardant flexible decorative brick for external thermal insulation of building exterior walls and a preparation method thereof. Background technique [0002] In recent years, severe fires caused by building insulation materials have occurred frequently, causing heavy casualties and property losses. In order to learn lessons from the “11.15” fires in the Jiaozhou Road teachers’ apartments in Shanghai and the “2.3” fires in Shenyang Wangchao Wanxin Building, on March 14, 2011, the Fire Department of the Ministry of Public Security issued a public document (2011) No. 65 "About Further Clarify the Relevant Requirements for Fire Supervision and Management of External Thermal Insulation Materials for Civil Buildings ", put forward emergency requirements for the use and management of thermal insulation materials for external walls of buildings...
