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 antistatic bionic quartzite and a preparation method thereof. The preparation method includes the following steps that firstly, modified resin is prepared; secondly, by weight, 80-90% of quartz, 8-12% of modified resin, 0.01-1% of a curing agent, 0.01-1% of a coupling agent, 3-5% of conductive powder, 1-3% of aluminum hydroxide powder and 0.1-2% of pigment are stirred to be uniform, and a mixture is obtained; thirdly, the mixture is distributed on a mould plate for the first time, vibratory compacting forming, demoulding and cutting are carried out, arrangement is carried out according to a preset pattern to obtain a semi-finished product, material distribution is carried out for the second time, vibratory compacting forming and drying forming are carried out, and then aftertreatment is carried out to obtain a finished product. Compared with existing bionic quartzite, the prepared bionic quartzite is scientific in blending, reasonable in preparation, stable in performance, high in mechanical strength and not prone to deformation or ageing; besides, by reasonably matching conductive powder, a luminous composite and antibacterial powder, the bionic quartzite has excellent antibacterial, luminous and antistatic properties, and the application range of the bionic quartzite is further widened.

Description

technical field [0001] The invention relates to the technical field of quartz stone, in particular to an antistatic 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] However...
