Abstract

An anti-bacteria anti-mould material based on diatomite ultrafine powder and a preparation method therefor are provided by the present invention, and belong to the technical field of diatom nano materials so that the problems of higher costs, poor long-term dispersion stability, and poor anti-bacteria anti-mould effects of existing anti-bacteria anti-mould materials are solved. The anti-bacteria anti-mould material based on diatomite ultrafine powder comprises the following components in parts by weight: 5-15 parts of an anti-mold agent S89; 5-15 parts of diatomite ultrafine powder; and 2-6 parts of nano zinc oxide ZnO. The anti-bacteria anti-mould material provided by the present invention has an negative ion average increase of 127-131 / s.cm2 and an antibacterial rate of 94% - 97%. The anti-bacteria anti-mould material based on diatomite ultrafine powder has strong anti-bacteria anti-mould capabilities, and can further release negative ions and purify air. Compared with the prior art, the anti-bacteria anti-mould material greatly reduces the cost and has better long-term dispersion stability due to the fact that aggregation is unlikely to occur.

Description

technical field [0001] The invention belongs to the technical field of diatom nanometer materials, and in particular relates to an antibacterial and antifungal material based on diatomite superfine powder and a preparation method thereof. Background technique [0002] Water-based latex paint for interior walls (referred to as interior wall paint) is an essential material for decoration, and can also be used as ceiling paint to decorate and protect interior walls and ceilings. The main types of architectural coatings in industrially developed countries abroad are latex paints, whose output generally accounts for 50% of the total output. In my country's architectural interior wall coatings, low-grade polyvinyl alcohol coatings are still the main ones, accounting for about 40% of the total output of coatings. Due to the poor quality of low-grade polyvinyl alcohol coatings, the output will gradually decline in recent years. At the same time, with the enhancement of people's awa...
