Abstract

The invention discloses an environment-friendly diatom mud decoration material and a preparation method thereof. The decoration material is prepared from the following raw materials in parts by weight: 60-80 parts of diatomite, 70-90 parts of quartz sand, 15-30 parts of sepiolite, 20-30 parts of talcum powder, 8-20 parts of calcium hydroxide powder, 5-10 parts of bamboo carbon fibers, 1-5 parts of polyester fibers, 0.6-2 parts of sodium perborate, 1-3 parts of nano-zinc oxide, 0.2-0.6 part of Kathon, 0.1-0.5 part of a dispersing agent, 0.2-0.8 part of a wetting agent and 0.1-0.3 part of a defoaming agent. The preparation method of the decoration material comprises the processes of purifying diatomite, mixing and carrying out ball milling. The environment-friendly diatom mud decoration material provided by the invention is safe and environment-friendly, has relatively good bacteria resistance, bacteriostasis, water resistance, mildew resistance and fire resistance and is suitable for being used as an internal wall coating, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly diatom mud decoration material and a preparation method thereof. Background technique [0002] Today, low-carbon environmental protection, energy conservation and emission reduction are the basic principles for the sustainable economic development of various countries in the world. With the development of society and the improvement of living standards, people's awareness of environmental protection and health has been significantly enhanced, and the requirements for the comfort and safety of the living environment are getting higher and higher. Indoor temperature, air relative humidity, and air quality are important environmental parameters for living comfort. When the indoor temperature is 20-23°C, the relative humidity is 50-60%, the VOC content is low, and the negative ion content is high, the human body feels comfortable and beneficial to ...
