Abstract

The invention is a kind of dual environmental protection building surface ornamenting material produced by using brick powders of grinded waste construction clay bricks as main materials and its producing method. The invention makes clay brick powders as main materials, and is compounded from such chemical industry materials as acrylic acid emulsion, sodium hexametaphosphate, sodium benzoate, glycol, trimethylene glycol, polydimethyl siloxanes, methylcellulose and titanium oxide powder as per certain proportion. The invention has simple technics, convenient and sanitary construction, and can be used both in upscale wall surface and surfaces of column, tablet and board. After ornamented, it has elegant and vivid brick wall style, especially suitably used for outer ornament and repair of building wall surfaces whose outer walls need brick wall structures.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a clay acrylic surface decoration material made of waste resources and a preparation method thereof. Background technique [0002] With the development of the economy, the development of urban construction has been brought about. At present, in the field of urban construction, on the one hand, a large number of abandoned dilapidated bricks and discarded clay building materials become construction waste and bring great pollution to the city. The accumulation of construction waste has seriously affected the ecological environment of relevant areas. People have gradually realized that it is an excellent sustainable resource for material processing. [0003] On the other hand, in the field of building surface decoration, there are continuous innovation requirements for water-based environmental protection surface decoration materials in order to minimize urban ...
