Abstract
An additive of efficient far infrared powder is prepared from natural inorganic ore (70-100 wt.%), alkali metal, transition metal, their oxides, or non-metal compound (0-30 wt.%) and rare-earth oxide (0-5 wt.%). Its advantages are high far infrared radiation coefficient at ordinary temp. widely available raw materials, simple process, and low cost.
Description
The present invention relates to a kind of efficient function far infrared radiation function flour additive agent composition and preparation technology thereof.
The industrial chemicals of crossing through processing treatment is mostly adopted in existing far-infrared functional material and preparation thereof, obtains by batch mixing, vacuum hotpressing or the high temperature method around knot.Its thermal treatment calcining is in order to impel its crystal conversion to improve infrared property.This preparation technology is strict to starting material composition and treatment temp, time and atmospheric condition, and cost is higher, and the product far-infrared radiation rate at normal temperatures that makes with this technology is lower.
Purpose of the present invention is exactly to provide far-infrared radiation rate height under a kind of normal temperature, starting material wide, the lower-cost additive of efficient far infrared powder in source and preparation technology thereof for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of additive of efficient far infrared powder, its prescription following (weight percentage): natural inorganic mineral 70～100%, basic metal, transition metal or basic metal, transition metal oxide or nonmetallic compound 0～30%, rare earth oxide 0～5%.
Described natural inorganic mineral is to contain aluminium, Si oxide is main, also have other metal oxide and various composite oxides, it is selected from one or more of following ore: mullite, trichroite, fluorite, calcite, alunite, sodium fluoroaluminate, coal gangue, tourmalinite, chlorite, attapulgite, silica, rutile, titanium iron ore, talcum, wollastonite, sepiolite, medical stone, optical calcite, rhombspar, montmorillonite, zeolite, rectorite leng, cured stone, feldspar, diopside, the tremolite, only monarch's stone, giant crystal stone, granite, good wine jade and kaolin, china clay, bauxite, chalk soil, mica, diatomite, wilkinite.
Described basic metal, transition metal or basic metal, transition metal oxide are selected from one or more of Sr, W, Mo, V, Pt, Zr, Fe, Ti, Mo, Ni, Ta, Ag, Co element or its oxide compound.
Described nonmetallic compound is selected from one or more in C, N, F, O, B family element oxide, carbide, nitride, fluorochemical, the boride.
Described rare earth oxide is selected from one or more of Sc, Y and La series elements oxide compound.
A kind of preparation technology of additive of efficient far infrared powder, it comprises following processing step: at first each group raw material is pulverized, press natural inorganic mineral 70～100% (weight) then, basic metal, transition metal or basic metal, transition metal oxide or nonmetal oxide 0～30% (weight), the proportioning of rare earth oxide 0～5% (weight) is matched material, calcined after should expecting again to mix, will calcine the further fine grinding pulverizing of good compound at last and obtain; Described calcining temperature is 350～1350 ℃, and described calcination time is 0.5～5 hour.
Described rare earth oxide can be obtained by rare earth metal and the direct burning of oxygen when calcining and activating, perhaps adopts oxyhydroxide, carbonate, nitride, the oxalate of heating rare earth element to make.
With traditional artificial far-infrared powder, promptly utilize the product of prior art manufacturing to compare, far infrared powder of the present invention uses as functional additive, the far-infrared radiation rate of its normal temperature can be up to more than 90%, and starting material mainly are derived from natural mineral, and the ratio of performance to price of product is better than artificial far-infrared powder.
Use as the far-infrared functional flour additive agent, it has function far infrared radiation function at normal temperatures, the wavelength that the far infrared rays of 4～14 μ m that sent and human body can absorb is complementary, penetration power that the far infrared rays tool that it gives off is certain and high radiant ratio, tangible thermogenetic effect is arranged after being absorbed by the body, it can promote the blood of human body circulation and improve metabolic function, have good health-care physiotherapeutic effect.
The present invention is by after matching inorganic mineral raw material and grinding and processing; at different formula for raw stock; can select for use also can be follow-up the high-temperature heat treatment process of making as artificial far infrared ceramic powder; make the powder of the corresponding grain size that obtains; function far infrared radiation function with normal temperature (20 ℃～50 ℃); its selection range is extensive, and processing treatment technology is simple, calcining need not the special atmosphere protection, and tooling cost is lower.
Pulverization process adopts mechanical crushing method, and jaw crusher is generally used in coarse crushing, in broken employing pair roller pulverizer, equipment in small, broken bits can select means processing treatment such as thunder grinds now, gyrosphere grinding machine, dry type vibratory mill, micronizer mill.For the powder additive that is applied in the far infrared functional fibre, need just can obtain satisfactory diameter of particle through case of wet attrition again, case of wet attrition can adopt equipment such as wet vibration mill, sand mill, wet type agitating ball mill to finish.
The different components that constitutes in view of raw material is to the contribution difference of the far-infrared radiation of 4～14 μ m, in follow-up poling processing technique, need to consider, the transformation temperature of part component is lower, the performance that the back does not just guarantee performance takes place to destroy in structure, thereby in conjunction with different starting material, be necessary to handle respectively differing temps, behind the different calcination times, remix evenly back uses, can guarantee in the wide region of 4～14 μ m, to realize high far-infrared radiation rate, and to some raw material, calcining is a very important procedure, by promoting the crystal conversion of raw material, the crystal formation that obtained performance is good, and improve its far infrared characterization.
