Problems solved by technology

[0002] Magnesite products are favored because of their low cost, light weight, and excellent corrosion resistance. Although they can meet certain requirements in ordinary use occasions, their own defects limit their wider promotion and application. There are mainly three Insufficient aspects: (1) low strength
(2) Moisture absorption and halogen return, warping and deformation
White spots are formed on the surface of the product, that is, back halogen; and due to the uneven expansion of magnesite products in the hydration process, the magnesite decorative board is warped and deformed, which seriously affects the decorative effect and popularization of this kind of board.
(3) Single purpose

Embodiment 1

[0035] First prepare the modifier, mix sodium phosphate, sodium tripolyphosphate, and hot water with a mass ratio of 1:1:10 to prepare 50 kg of the modifier, and set it aside for use. Then weigh 200 kilograms of magnesite powder, 60 kilograms of wood chips, 30 kilograms of perlite, 200 kilograms of bittern, 16 kilograms of modifiers, and 1 kilogram of polysiloxane. Mix 200 kg of brine with 16 kg of modifier, add 0.6 kg of polysiloxane, and stir evenly. Add 2 / 3 (i.e. 134 kg) of the magnesite powder required for each batch into the mixer, add the mixed solution of brine and modifier under stirring, stir for about 10 minutes, then add the remaining 66 kg of magnesite powder , stirred for 3 minutes, and the stirring speed was 60-120 rpm. Then add 72 kilograms of the mixture of sawdust and water, 36 kilograms of the mixture of perlite and water, and 0.4 kilogram of the remaining defoamer, and stir for 6 minutes.

Embodiment 2

[0038] First prepare modifier, aluminum sulfate, urea-formaldehyde resin, naphthalenesulfonic acid NNO, sodium phosphate, triethanolamine, hot water are mixed according to the mass ratio of 1: 1: 1: 1: 9: 10 to prepare 50 kg of modifier ,stand-by. Then weigh 200 kilograms of magnesite powder, 60 kilograms of wood chips, 30 kilograms of perlite, 200 kilograms of bittern, 16 kilograms of modifiers, and 1.5 kilograms of polysiloxanes. Mix 200 kg of brine with 16 kg of modifier, add 0.7 kg of polysiloxane, and stir evenly. Add 2 / 3 (i.e. 134 kg) of magnesite powder required for each batch into the mixer, add the mixed solution of brine and modifier under stirring, stir for about 10 minutes, then add the remaining 66 kg of magnesite powder , stirred for 3 minutes, and the stirring speed was 60-120 rpm. Then add 73 kilograms of the mixture of sawdust and water, 38 kilograms of the mixture of perlite and water, and 0.8 kilogram of the remaining defoamer, and stir for 6 minutes.

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 [0001] The invention belongs to the technical field of glass magnesium boards, and in particular relates to an infrared glass magnesium board and a preparation method thereof. The prepared infrared glass magnesium board has comprehensive properties such as health care function, high infrared emission efficiency, high strength, no moisture absorption and halogen return, and no warping and deformation. Background technique [0002] Magnesite products are favored because of their low cost, light weight, and excellent corrosion resistance. Although they can meet certain requirements in ordinary use occasions, their own defects limit their wider promotion and application. There are mainly three Insufficient aspects: (1) low strength. At present, the reinforcing materials used in most magnesite products are non-woven fabrics and ordinary glass fibers. Because the production method of magnesite products is to roll the mixture, glass fibers, and non-woven fabrics, a...
