Problems solved by technology

The main shortcomings of metal ion antibacterial agents are: 1. Metal ions themselves may cause harm to human health or the environment; 2. Must be in direct contact to have antibacterial or antibacterial effects; Ions are used to destroy bacterial proteins, thereby inhibiting bacterial growth. The release may be large in the early stage and have a good effect, but as time goes on, after a period of metal ion release, the later concentration gradually decreases, and the long-term effect is difficult to guarantee; 4 , metal ion antibacterial agent powder is easy to cohere, not easy to disperse evenly

Abstract

The invention relates to an antibacterial formaldehyde-removing composite inorganic artificial stone material and a preparation method thereof. The material comprises the following components in parts by mass: 40 to 65 parts of aggregate; 25 to 40 parts of cement; 1 to 10 parts of a composite modifier; 0.001 to 0.008 part of a water reducing agent; 0.0002 to 0.002 part of a retarder; 6.5 to 15 parts of water; and 0.0008 to 0.005 part of modified antibacterial powder. According to the antibacterial formaldehyde-removing composite inorganic artificial stone, the modified antibacterial powder capable of continuously radiating terahertz waves is used for replacing a metal ion antibacterial agent to prepare the artificial stone, direct contact is not needed, good harmful gas decomposition and sterilization effects are achieved, environmental pollution is reduced, and human health is facilitated.

Description

technical field [0001] The invention belongs to the field of decorative materials, and in particular relates to an antibacterial and formaldehyde-removing composite inorganic artificial stone and a preparation method thereof. Background technique [0002] Artificial stone is a new type of decorative material. It has a hard texture and a compact structure. It has the characteristics of wear resistance, pressure resistance, high temperature resistance, corrosion resistance, and impermeability. It is a reusable environmentally friendly and green new building interior decoration material. . [0003] Indoor furniture usually contains formaldehyde, and indoor dark corners are prone to breed bacteria, which affects human health. At present, most of the existing inorganic artificial stones in the market do not have antibacterial and formaldehyde removal effects, and very few have antibacterial effects, and the antibacterial effect is mainly achieved by adding metal ion antibacteria...
