The invention relates to the technical field of textile finishing and specifically relates to a far infrared textile fabric preparation method. The invention further provides a composite material based on GO-TiO-ZrO2, wherein the three materials are connected through chemical bonds, a traditional textile material with far infrared emission and a novel far infrared emitting material graphene oxideare compounded, and then the graphene oxide / titanium dioxide / zirconium dioxide composite material is combined with cotton textiles through a crosslinking effect of waterborne polyurethane in an after-finishing mode; thus, a far infrared emission rate of textiles is improved; furthermore, the composite material has the advantages of simpleness in preparation and low cost.

The invention discloses a preparation method for charcoal-based far-infrared composite materials, comprising the following steps: (1), the following components are taken as raw materials based on weight percentage: 50%-95% of charcoal, 0.5%-30% of tourmaline, 1-10% of clay and 0.5-20% of maifan stone; (2), all the materials are put into deionized water, then binder is added to the water for ball-mill mixing; (3), the mixture obtained from the step (2) goes through high pressure forming and is then put into a vacuum graphite sintering furnace and calcined in a protective atmosphere of nitrogen;(4), the calcined product obtained from the step (3) is cooled to room temperature to get the charcoal-based far-infrared composite material. The invention also discloses the charcoal-based far-infrared composite material prepared through the method. The charcoal-based far-infrared composite material of the invention has high far-infrared emissivity and is environmental-friendly and healthy.

The invention relates to a microcrystal bamboo charcoal purple sand composite pottery material and application of the microcrystal bamboo charcoal purple sand composite pottery material. The microcrystal bamboo charcoal purple sand composite pottery material is composed of, by weight, 5-40% of microcrystal bamboo charcoal powder, 40-60% of purple sand powder, 10-30% of attapulgite, 5-30% of kieselguhr and 1-5% of binder in a mixing mode. The microcrystal bamboo charcoal purple sand composite pottery material can be used for manufacturing a microcrystal bamboo charcoal purple sand composite pottery, the steps for manufacturing the microcrystal bamboo charcoal purple sand composite pottery are specifically forming, air drying, drying, calcination and cooling, and therefore the microcrystal bamboo charcoal purple sand composite pottery can be obtained. According to the microcrystal bamboo charcoal purple sand composite pottery material and the application of the microcrystal bamboo charcoal purple sand composite pottery material, through different raw material ratios and calcination crafts, the manufactured microcrystal bamboo charcoal pottery after processing is low in firing shrinkage coefficient, high in bending strength and strong in adsorption of formaldehyde, phenol, sulfur dioxide, TVOC and other hazardous substances and can be manufactured into pottery materials of different water adsorption rates as required.

The invention provides a far-infrared quartz tube applied to a low-temperature non-combustible electronic smog vaporizer. The far-infrared quartz tube is composed of a conductive film layer, a far-infrared coating and a quartz tube connected in sequence; wherein, the far-infrared coating is composed of a far-infrared Infrared coatings are formed. Far-infrared coatings are prepared from the following components by weight: 30-40 parts of pure acrylic emulsion, 2-3 parts of wetting and dispersing agents, 10-15 parts of fillers, 90-100 parts of solvents, film-forming 1-2 parts of auxiliary agent, 40-45 parts of far-infrared powder, 7-10 parts of tin tetrachloride, 3-4 parts of modifier; the conductive film layer is formed by conductive paste, and the conductive paste consists of the following parts by weight It is prepared from the following components: 4-5 parts of sodium carboxymethylcellulose, 80-90 parts of N,N-dimethylacetamide, and 12-18 parts of conductive graphite. The invention also provides a preparation method of the far-infrared quartz tube. The far-infrared quartz tube provided by the invention adopts a far-infrared heating mode and has better heating performance.
