Problems solved by technology

Tourmaline can release negative oxygen ions, but tourmaline releases negative oxygen ions at a low rate and low concentration, which cannot meet the demand
[0006] At present, CN201310606452.X discloses a perlite calcium silicate board capable of releasing negative oxygen ions and its preparation method. However, the obtained anion-induced perlite calcium silicate board has a low efficiency of inducing negative ions, and the raw material tourmaline used has a trace amount of radioactivity. , tourmaline content is large will cause harm to the human body

Abstract

The invention provides a perlite calcium silicate board inducing negative ions. The perlite calcium silicate board is prepared from the following components in percentage by mass: 30 to 65 percent of expanded perlite, 10 to 20 percent of rapid-hardening sulphate aluminum cement, 10 to 20 percent of nano-tourmaline, 5 to 10 percent of nanometer titania, 5 to 10% of ultrafine calcium stearate and 5 to 10 percent of ultrafine talcum powder. According to the perlite calcium silicate board of the invention, the nano-tourmaline, the nanometer titania, the ultrafine calcium stearate and the ultrafine talcum powder are reasonably matched, so as to improve the negative ion inducing effect of the perlite calcium silicate board, long-term release of negative ions is realized, pollutants such as formaldehyde can be removed, the moisture absorption and discharging property is good, the air permeability is good, the effects of fire and sound insulation, and mildew and corrosion resistance are realized, the production and preparation cost is low, and the tourmaline content is small. By adding an effective radiation shield agent, the radioactive possibility of the tourmaline is reduced, the perlite calcium silicate board is more environmentally friendly and healthier, and is a green ecological building product.

Description

technical field [0001] The invention relates to a building material, in particular to a perlite calcium silicate board which induces negative ions and a preparation method thereof. Background technique [0002] Perlite calcium silicate board expanded perlite is a kind of white granular material with a honeycomb structure inside, which is made of perlite ore after preheating and instantaneous high-temperature roasting and expansion. The principle is: perlite ore is crushed to form ore sand with a certain particle size, preheated and roasted, and heated rapidly (above 1000°C), the water in the ore sand is vaporized, and expands inside the softened glassy ore sand to form a porous structure and volume expansion 10-30 times non-metallic mineral products. Perlite is divided into three forms according to its expansion technology and use: open cell (open cell), closed cell (closed cell), hollow cell (balloon). [0003] However, the expanded perlite insulation board is made of expa...
