Antibacterial putty powder with long service life and preparation method thereof

Abstract

The invention discloses an antibacterial putty powder with long service life. The antibacterial putty powder is prepared from the following raw materials in parts by weight: white cement, redispersible latex powder, carboxymethyl cellulose, modified starch ether, a talcum powder, an ash calcium powder, a negative ion powder, a far-infrared ceramic powder, a bamboo charcoal powder, a titanate coupling agent, a silvery white vermiculite powder, paraffin wax, a ground calcium carbonate powder, kaolin and glass fiber. The invention also discloses a preparation method of the antibacterial putty powder with long service life. The antibacterial putty powder has the advantages that the raw materials are environment-friendly, the preparation technology is simple, the construction and grinding are easy, and the adhering strength is high; the heat insulation and isolation effects are realized, the water-resistant property and adhering property are realized, the uniformity is good in the drying process, and the flatness is good; the excellent health-care and anti-corrosive properties are realized; the antibacterial putty powder is a functional putty powder product, and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a putty powder with long antibacterial service life and a preparation method thereof. Background technique [0002] The heat energy in the air is transferred in three ways: conduction, convection and radiation, of which more than 90% comes from the transfer of radiant heat. In order to slow down the impact of these heat transfers on people's living and living, it is necessary to use thermal insulation materials on the surface of buildings, so that the wall materials can improve the thermal insulation performance in summer and improve the thermal insulation performance in winter. And putty is a kind of building decoration material for flat wall surface, is a kind of thick paste paint, the purpose of brushing putty is to fill the pores, depressions and correction of the curve deviation of the construction surface. In addition, putty can also play a variety of special fu...

AI Technical Summary

Problems solved by technology

[0003] Traditional putty powder mainly uses white cement and gray calcium powder as raw materials, and generates stable calcium carbonate by solidifying itself and absorbing carbon dioxide in the air. Therefore, the calcification reaction of gray calcium powder (calcium hydroxide) in traditional putty powder mainly occurs in the putty The surface layer of the powder coating, and the inner layer of the coating also has a large amount of unstable calcium oxide and calcium hydroxide, which leads to the following problems in the traditional putty powder coating: weak structure, short service life, easy peeling and cracking, calcification The rate is not high, the hardness of the inner layer is low, the waterproof performance is poor, the adhesion is not strong, and it does not have health care functions
