Preparation method of antibacterial powder, antibacterial powder and antibacterial artificial stone plate using antibacterial powder

Abstract

The invention discloses a preparation method of antibacterial powder, the antibacterial powder and an antibacterial artificial stone plate using the antibacterial powder. The method comprises the following steps: A, mixing glass raw materials to form a glass material mixture; B, melting the glass material mixture to obtain borosilicate glass C capable of dissolving out antibacterial metal ions, cooling the borosilicate glass C, and carrying out split-phase heat treatment; and D, adding the borosilicate glass subjected to heat treatment into a ball mill for ball milling to form the antibacterial powder. According to the preparation method of the antibacterial powder provided by the technical scheme, the antibacterial effect is good, operation is simple, and preparation is convenient, overcoming the defects in the prior art. The antibacterial powder prepared by the preparation method of the antibacterial powder is strong in antibacterial effect, high in stability, good in safety and environmental protection property and low in cost. The invention further provides the antibacterial artificial stone plate using the antibacterial powder, and the antibacterial rate of the plate can reach90% or above.

Description

technical field [0001] The invention relates to the field of antibacterial materials, in particular to a preparation method of antibacterial powder, the antibacterial powder and an antibacterial artificial stone plate using the antibacterial powder. Background technique [0002] With the advancement of stone technology, consumers have begun to have higher and higher requirements for the impact of stone on the home environment, especially stone with bactericidal and antibacterial functions has become very popular abroad and is a basic requirement for stone. [0003] In the past, sterilizing and antibacterial agents containing silver ions were commonly used in stone materials. Since metallic silver is a precious and rare metal, it is expensive and costly. Therefore, it has become the biggest obstacle to the popularization of stone materials with bactericidal and antibacterial functions.

Problems solved by technology

[0003] In the past, sterilizing and antibacterial agents containing silver ions were commonly used in stone materials. Since metallic silver is a precious and rare metal, it is expensive and expensive.

Therefore, it has become the biggest obstacle to the popularization of stone materials with bactericidal and antibacterial functions.

In addition, silver ions will darken the color in stone, which also limits its application in some aspects.

At present, bactericidal antibacterial agents include organic bactericidal antibacterial agents and inorganic bactericidal antibacterial agents. Organic bactericidal antibacterial agents have good bactericidal effects, but their effective time is short and prone to failure

Elemental nano-metal powder is widely used in inorganic materials, such as nano-silver, nano-zinc oxide, nano-titanium dioxide, etc. This kind of inorganic material is expensive and has few sources, so it is difficult to widely promote it in stone materials.
