A kind of preparation method of infrared ceramics vitrified brick
Technical field
The invention belongs to the infra-red china building material technical field, be specifically related to a kind of preparation method of infrared ceramics vitrified brick.
Background technology
Infra-red china is meant to have than high radiant rate with than the pottery of high radiance in certain infrared band scope.Because ir radiation is easily absorbed by object and converts heat to, so infra-red china widely develops as a kind of photo-thermal converting function material in recent years.
At present, high emissivity radiative material on the market mostly is the infrared radiation ceramic of transition element series of compounds and low bulk infrared radiation ceramic, carbide, nitride and boride of series such as trichroite, mullite or the like, the application of succeeding at the aspects such as high-purity insulation adamantine membrane of the high-temperature energy-saving coating material of industrial furnace, well heater, and obtained good Infrared Heating and energy-saving effect.Though they meet the requirements on performance, these products are not that the raw materials for production costliness is exactly that sintering program complexity or the like causes price quite high, are difficult to apply in such as large building material product such as ceramics vitrified brick.
Architectural pottery vitreous brick is because have intensity height, corrosion-resistant, and generous characteristics attractive in appearance are very extensive in the application of household, life, public place of entertainment.And the architectural pottery vitreous brick that has high infrared radiation at normal temperatures not only has good decoration effect; simultaneously can also purify human living living environment; human body is played antibiotic, function of health care; it is the friendly type material of construction of a kind of fine environment; yet; up to now, people also do not find a kind of preparation method of ideal infrared ceramics vitrified brick.
Summary of the invention
The objective of the invention is to develop have at normal temperatures the high infrared radiation performance, to the human body beneficial, cheap and the most closely-related architectural pottery vitreous of people's daily life daily life brick.
The preparation method of a kind of infrared ceramics vitrified brick of the present invention; adopt natural mineral such as feldspar commonly used in the building tile manufacturing; kaolin is as the base substrate basic components; add wherein at least a of chromite waste residue and copper tailings waste material as additive; its composition is by weight percentage: feldspar: 12~25%; kaolin: 15~30%; talcum: 3%~11%; washing mud: 28%~45%; copper tailings waste material: 0~10%; the chromite waste residue: 0~15%, through pulverizing; mixing and ball milling; sieve; dry; granulation; moulding; fire; polishing obtains at normal temperatures, and 8~14 μ m infrared band radiant ratios reach 0.86~0.94 far infrared architectural pottery vitreous brick.
According to Wien's displacement law, λ
mT=2898.8 ± 0.4 μ mK can calculate the human body radiation peak wavelength and be about 9.3 μ m, belongs to far infrared band.Simultaneously because the vibrational frequency of our human body group, the far infrared radiation of wavelength 9~11 μ m is easy to be absorbed by human body skin, and wavelength is that the frequency of far-infrared radiation of 10~16 μ m is consistent with the natural vibration frequency of human body organo-functional group peptide chain.So when the far infrared radiation human body, human body surface is accepted far infrared rays, and from outward appearance to inner essence conduction infiltration, be absorbed the generation thermogenetic effect, produce resonance, sympathetic response with the in-vivo tissue cell, promoted activity.And owing to produce thermogenetic effect, make the human microvascular expansion, autorhymicity is strengthened, and blood circulation is accelerated, and makes the cell activity increased response, has quickened the exchange of substance of cell and blood, thereby has promoted the metabolism of body.Far-infrared radiation can also be destroyed the growth cycle of bacterium simultaneously, has tangible bacteriostatic action.
The present invention is in conjunction with building ceramics factory natural mineral raw commonly used; add the waste residue after a certain proportion of factory chromite is smelted, the copper tailings waste material after the copper smelting more respectively; in the architectural pottery that has obtained high emissivity, reduce its cost again greatly; not only make this product increase new health care antibacterial, and have the meaning of effective utilization of waste material and environment protection.
