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 anti-radiation bionic quartz stone and a preparing method thereof. The preparing method includes the following steps that A, modified resin is prepared; B, by weight, 80-90% of quartz, 8-12% of modified resin, 0.01-1% of curing agent, 0.01-1% of coupling agent, 1-5% of nanometer bamboo charcoal, 1-3% of aluminum hydroxide powder and 0.1-2% of pigment are stirred uniformly to obtain a mixed material; C, the mixed material is distributed on a template for the first time, vibration pressing forming, demolding and cutting are carried out, and the mixed material is arrayed according to a preset pattern to obtain a semi-finished product; secondary material distribution is carried out, vibration pressing forming and drying forming are carried out, and then the finished product is obtained through postprocessing. Compared with existing bionic quartz stone, the manufactured bionic quartz stone is scientific in matching, reasonable in preparation, stable in performance, high in mechanical strength and not prone to deformation or ageing. The bionic quartz stone has excellent antibacterial, deodorizing and anti-radiation performance by reasonably matching the nanometer bamboo charcoal, deodorant and antibacterial powder, and the application range of the bionic quartz stone is further broadened.

Description

technical field [0001] The invention relates to the technical field of quartz stone, in particular to a radiation-proof 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. [0004] How...
