Inorganic stone-like dry powder coating for exterior wall surface

Abstract

The invention belongs to the technical field of coatings, and relates to an inorganic stone-like dry powder coating for an exterior wall surface. The inorganic stone-like dry powder coating for the outer wall surface is prepared from the following raw materials in parts by weight: 30-40 parts of wollastonite, 10-20 parts of colored quartz sand, 20-30 parts of ash calcium powder, 10-25 parts of talcum powder, 1-10 parts of 0.5 fiber, 1-8 parts of hydroxypropyl cellulose and 0.5-5 part of hydroxyethyl cellulose. The inorganic stone-like dry powder coating for the exterior wall surface is good instone-like effect, environmental protection performance and crack resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an inorganic stone-like dry powder coating for exterior walls. Background technique [0002] As my country's protection of natural resources and the country's environmental protection and energy conservation policies and related regulations become more and more stringent, the cost of mining, processing and transportation of natural stones continues to rise, which affects the application of natural stones in the field of architectural decoration to a certain extent. In addition, the continuous promotion and development of building energy conservation has also made the application of external thermal insulation technology on building exterior walls popularized and promoted. However, the stone decoration process is carried out on the thermal insulation base layer, and the construction process is relatively complicated, and many new thermal insulation forms cannot be adopted.

AI Technical Summary

Problems solved by technology

Although the dry powder coating for exterior walls has good performance and environmental performance, it is poor in decoration.

If the stone-like paint is prepared directly by adding colored quartz sand and other raw materials for preparing stone-like paint, the prepared paint has poor crack resistance and cannot meet the needs of practical applications.
