Problems solved by technology

However, due to the high sintering temperature of ceramics, the complicated preparation process, and the surface of ceramics is easily polluted, it is inconvenient to clean and regenerate, and there are many inconveniences in long-term use, and there are certain limitations.
Chinese patent application No. 200910096190.0 discloses a bamboo charcoal-tourmaline far-infrared composite material, which is composed of bamboo charcoal and tourmaline, and the far-infrared emissivity is as high as 0.93, but the preparation method uses a large amount of tourmaline (40- 60%), the requirements for sintering conditions are relatively strict, and the production cost is high, which is unfavorable for popularization and application
However, the glass sheet is only coated with tourmaline powder on the glass substrate. The tourmaline powder is easy to fall off, and the functionality and durability of the effect are poor.

Abstract

The invention relates to a composite tourmaline / glass material and a preparation method thereof. The composite material comprises the following raw materials by weight percent: 5%-30% of tourmaline and 70%-95% of glass, wherein the tourmaline is selected from at least one of iron tourmaline, lithium tourmaline and magnesium tourmaline; the glass comprises the following components by weight percent: 40%-70% of Bi2O3, 10%-20% of B2O3, 1%-7% of Al2O3, 10%-20% of ZnO, 5%-10% of CaO and 1%-13% of SiO2, wherein the sum of the weight percent is 100%. The preparation method comprises the following steps: (1) preparing small glass particles; (2) preparing the composite tourmaline / glass material: uniformly mixing the tourmaline with the glass, firing at 600-900 DEG C, and preserving heat to obtain the composite tourmaline / glass material with relatively high far-infrared emission performance.

Description

technical field [0001] The invention relates to the technical field of inorganic materials, in particular to a tourmaline / glass composite material and a preparation method thereof. Background technique [0002] In recent years, far-infrared health care products have become more and more popular and loved by people. Chinese patent application No. 200410012274.9 discloses a composite material containing tourmaline. The composite material is composed of tourmaline, ferrite permanent magnet, coupling agent and epoxy resin, and it is integrated into bedding, which can realize ecologically healthy sleep and achieve the purpose of promoting health. However, this composite material simply mixes tourmaline powder and magnetic material together, and is cured by resin, because tourmaline powder is easy to agglomerate and has poor dispersibility, so the effect of applying it to bedding is not good. Chinese patent application No. 200710027741.9 discloses a ceramic membrane water purifi...
