Abstract

The invention relates to dry-powder paint based on surface-modified shell powder, which belongs to the technical field of inner wall dry-powder paint. The surface modified shell powder used in the dry-powder paint is calcined and catalyzed at a high temperature, so that the surface porosity of the shell powder can be improved; and gel-form titanium dioxide, active white clay and white bamboo charcoal are selected to absorb the surface of the high-temperature calcined shell powder. By virtue of the high-temperature calcining surface absorption, the surface energy of the shell powder is high, the shell powder is easy to agglomerate in an application process, the agglomeration results in cracks of a dry film when heated, and the heat resistance and aging resistance of the material are reduced. A titanate coupling agent is used for performing the surface modification treatment on the shell powder, and the surface energy can be reduced, so that the modified shell powder can be uniformly dispersed in a system, and the heat resistance and aging resistance of a paint film can be improved. The problems of an indoor wall material such as yellowing, mildew, bubbling, discoloration, cracks, short service life, and breeding of a great amount of bacteria after being wetted can be effectively avoided, and the dry-powder paint has the characteristics that the harmful gases in the air can be absorbed, and the bacteria proliferation can be inhibited.

Description

technical field [0001] The invention belongs to the technical field of dry powder paint for interior walls, in particular to a dry powder paint based on surface-modified shell powder. Background technique [0002] In today's technology, as people's demand for health awareness continues to increase, traditional wall materials have a significant impact on residents' comfort and health due to the release of harmful substances and odors. The environment where traditional wall materials exist, such as formaldehyde, benzene, ammonia, radon, organic compounds, TVOC, and heavy metal pollution. [0003] Shell powder coatings are born in response to needs, meeting people's health, environmental protection, and aesthetic needs for modern wall materials. Since then, interior wall decoration materials have entered a new era-"shell powder era". Most of the shell powder coatings currently used are raw shell powder and calcined shell powder. Although raw shell powder coating itself does n...
