Problems solved by technology

[0006] At present, the society uses more functional products such as diatom mud paint, algae calcium board, etc. The main raw material used is diatom mud, which consumes a lot of resources. Although the product has a certain function of releasing negative oxygen ions, its release is low. The effects of purifying formaldehyde and regulating climate are not very obvious
At the same time, the widely marketed air purification gas products are mainly based on the principle of electric excitation to generate negative oxygen ions, which consumes a lot of energy, and at the same time generate ozone that is harmful to the human body, and the purification effect of formaldehyde and PM2.5 of the product is also very difficult. Achieve more than 75% of the national standard
[0007] At present, CN201410141001.8 discloses a gypsum board that can release negative oxygen ions and its preparation method. However, the efficiency of the induced negative ion gypsum board to induce negative ions is low. Tourmaline can release negative oxygen ions, but tourmaline can release negative oxygen ions. The rate is low and the concentration is low, which cannot meet the demand, and there is a small amount of radioactivity, and the large content of tourmaline will cause harm to the human body

Abstract

The invention provides a gypsum board capable of inducing anions. The gypsum board comprises a gypsum board material and an anion addictive, wherein the anion addictive is prepared from nano-tourmaline, nanometer titania, superfine calcium stearate and superfine talcum powder. Through reasonable arrangement of the nano-tourmaline, the nanometer titania, the superfine calcium stearate and the superfine talcum powder, the induction effect of the anions is improved; the anions can be permanently released; the anion induction efficiency is high; pollutants, such as formaldehyde can be purified; the gypsum board is good in moisture absorption and desorption property, good in breathability, fireproof, soundproof, corrosion-proof, mould-proof, low in preparation cost and relatively low in tourmaline content; and through adding an effective radiation shielding agent, the radioactivity possibility of the tourmaline is reduced and the gypsum board is more environment-friendly and healthier, and thus is a green ecological building product.

Description

technical field [0001] The invention relates to a building material, in particular to a gypsum board for inducing negative ions and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of health and environmental protection awareness, higher requirements are put forward for the selection and use of materials for home decoration. How to meet people's use requirements in the interior decoration materials of increasingly competitive furniture has become a priority for major manufacturers. [0003] Today, when social pollution is getting worse and people's living environment is getting worse, as people pay more and more attention to health, green ecological building materials have become the key direction of new material research. Green ecological building materials refer to those materials with good performance and excellent environmental coordination. Good environmental coordination refers to less r...
