Abstract
An infrared glass magnesium plate and a preparation method belong to the glass magnesium plate technical field. Light burned magnesite powder (mainly MgO), bittern (MgCl2 question mark 6H2O), fillers (perlite, sawdust), glass fibers, non-woven fabrics, modifiers and water are used as main raw materials to prepare glass magnesium plates with high quality. And infrared glass-ceramics (MgO-Al2O3-SiO2, MAS) fibers are used to replace the glass magnesium plates to prepare used common glass fibers. And the infrared glass-ceramics are arranged on the external or the middle of the glass magnesium plate in a way of to obtain a glass magnesium plate with high infrared emissivity. The invention is characterized in that the glass magnesium plate is provided with high strength and obvious medical and health function. And the glass magnesium plate has the advantages of not moisture absorbing performance, dehylogenation and warpage-free, which can be widely used in the fields of building, fireproofing, medical, health, etc.
Description
Technical field
The invention belongs to glass magnesium plate technique field, particularly a kind of infrared bo-mei board and preparation method.The infrared bo-mei board of preparation is with health role, high IR emission efficiency, higher intensity, the nonhygroscopic over-all propertieies such as halogen, not buckling deformation of returning.
Background technology
Magnesite product is because of its cost is low, in light weight, fine corrosion resistance is favored, though can satisfy certain requirement in common use occasion, but because the defective of self has limited its promotion and application more widely again, mainly have the deficiency of three aspects: (1) intensity is low.The employed strongthener of present most of magnesite product is non-woven fabrics and simple glass fiber, because the making method of magnesite product is that blended stock, glass fibre, non-woven fabrics are formed by roll-in, maintenance is dried then.The intensity of Zhi Bei magnesite plate depends primarily on the intensity of strongthener and the wettability of compound and strongthener in this way.The resistance to acids and bases of simple glass fiber is weaker than the resistance to acids and bases of devitrified glass fibre, therefore replaces glass fibre can significantly improve the intensity of this strongthener and magnesite product with devitrified glass fibre.(2) damp suction surface halide accumulation, buckling deformation.Under the environment of humidity, the free magnesium chloride on magnesite product surface can absorb airborne moisture and form its aqueous solution.Be adsorbed on product surface with the globule, and the free magnesium chloride of goods inside can dissolve also by the capillary-size pore adsorption moisture that is communicated with the surface, and with moisture evaporation by inside to surface transport.After the surface-moisture evaporation.Just form white dot at the goods table, promptly return halogen; And, had a strong impact on the decorative effect of this kind sheet material and promoted the use of because magnesite product causes the magnesite decorative sheet to produce buckling deformation in the differential expansion of hydration process.(3) purposes is single.Present most magnesite product is only as general structure, fire-retardant material, but major part is used to have people's active place, if use infrared magnesite material can not only play the effect of structure, fire-retardant material, but also can accumulation of heat, and launch infrared rays, will make the place that makes up by glass magnesium plate have significant accumulation of heat, infrared health function.
Therefore, the present invention at first goes out the nonhygroscopic high-quality magnesite product that returns halogen, not buckling deformation by suitable prescription and prepared, then with strongthener---the glass fibre in the alternative traditional magnesite product of infra-red devitrified glass fibre cloth, make and have the high IR emission efficiency, high strength, the nonhygroscopic infrared bo-mei board that returns halogen, not buckling deformation.
Summary of the invention
The invention reside in provides a kind of infrared bo-mei board and preparation method, this infrared bo-mei board to have higher infrared rays emission efficiency and intensity, and nonhygroscopicly returns halogen, buckling deformation, has the good health care effect.
Infrared bo-mei board of the present invention is made up of infra-red devitrified glass fibre, magnesite slip, non-woven fabrics, properties-correcting agent, wherein infra-red devitrified glass fibre accounts for 8～12wt.% of gross weight, the magnesite slip accounts for 85～90wt.% of gross weight, non-woven fabrics accounts for 0.2～1.0wt.% of gross weight, and properties-correcting agent accounts for 0.5～2.5wt.% of gross weight; The structure of glass magnesium plate is that the outside or the centre of glass magnesium plate is compounded with infra-red devitrified glass fibre.
The composition of infra-red devitrified glass fibre of the present invention is MgO, Al
2O
3, SiO
2, Fe
2O
3, MnO, CuO, wherein the weight percent between each composition is respectively that MgO is 12～16wt.%, Al
2O
3Be 20～25wt.%, SiO
2Be 40～45wt.%, TiO
2Be 3～8wt.%, Fe
2O
3Be 6～13wt.%, MnO is 4～8wt.%, and CuO is 2～6wt.%, and microstructure is a Jin green stone solid solution structure.
Magnesite slip of the present invention is by magnesia MgO, halogen sheet MgCl
26H
2O, filler, water are formed, wherein MgO/MgCl
2Mol ratio be 10～12, H
2O/MgCl
2Mol ratio be 12～18, the packing quality mark is 20～25wt.% of magnesia, filler is perlite and wood chip, the mass ratio of perlite and wood chip is 3: 2.
Properties-correcting agent of the present invention by in Tai-Ace S 150, urea-formaldehyde resin, naphthene sulfonic acid NNO, sodium phosphate, trolamine, the hot water two or more or all form, the weight ratio between each composition is (0～1.5): (0～2): (0～1): (0.5～1.5): (0～10): (5～12).
The design of proportioning raw materials
The present invention selects light-burned magnesia (being mainly MgO), halogen sheet (MgCl
26H
2O), filler (perlite, wood chip), glass, infra-red devitrified glass fibre, non-woven fabrics, properties-correcting agent and water are main raw material.Get MgO/MgCl
2Mol ratio be 10～12, there is excessive unreacted MgCl in the too little meeting of this ratio
