Problems solved by technology

[0004] However, there are few reports about bionic quartz stone with good uniformity and stable antibacterial function.
Moreover, the existing bionic quartz stone is generally a product with a single function, such as antibacterial, antistatic, etc., that is, one product does not have multiple functions, which greatly limits its application range and needs to be further improved.

Abstract

The invention discloses an antibacterial deodorant bionic quartz stone and a preparation method thereof. The preparation method comprises the steps of: A, preparing modified resin; B, by weight percentage, mixing 80-90% of quartz, 8-12% of modified resin, 0.01-1% of a curing agent, 0.01-1% of a coupling agent, 3-8% of a deodorant, 1-3% of aluminum hydroxide powder and 0.1-2% of pigment evenly to obtain a mixed material; and C, subjecting the mixed material to first distribution on a template, conducting vibration molding, demoulding and cutting, and performing arrangement according to a preset pattern so as to obtain a semi-finished product; and then conducting second distribution, conducting vibration molding and drying molding, and then performing after-treatment to obtain a finished product. Compared with existing bionic quartz stone, the bionic quartz stone prepared by the method provided by the invention has the advantages of scientific compounding, reasonable preparation, stable performance, high mechanical strength, difficult deformation and difficult aging. Also through reasonable collocation with the deodorant and antibacterial powder, the synergistic effect of the two endows the bionic quartz stone with excellent antibacterial and deodorizing performance, thus further broadening the application scope of bionic quartz.

Description

technical field [0001] The invention relates to the technical field of quartz stone, in particular to an antibacterial and deodorizing bionic quartz stone and a preparation method thereof. Background technique [0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market. [0003] Bionic quartz stone has the advantages of low shrinkage, low manufacturing cost, easy processing, rich color, outstanding product performance and high hardness. It has been made into various industrial and civil flooring and decorative materials, and is widely used in industrial production and people's daily life. In life, it is used as a decorative material for floor tiles and walls...
