preparation example Construction

[0033] The present invention provides a kind of preparation method of ceramic fiberboard, comprising:

[0034] Mix aluminum silicate fiber, adsorbent, reinforcing fiber, inorganic binder and water evenly, then mix with flocculant, form and dry to obtain ceramic fiber board;

[0035] The weight ratio of the aluminum silicate fiber, adsorbent, reinforcing fiber, inorganic binder, water and flocculant is (40-70): (5-30): (1-5): (20-80): ( 4000~10000): (1~3).

[0036] In the present invention, firstly, the aluminum silicate fiber, adsorbent, reinforcing fiber, inorganic binder and water are uniformly mixed. The present invention is not limited to the mixing method and container, and the mixing method in the pulping process well known to those skilled in the art is sufficient, preferably uniformly dispersed in the pulping tank. More preferably, water, aluminum silicate fiber, adsorbent, reinforcing fiber, and inorganic binder are uniformly mixed in this order. The addition seque...

Embodiment 1

[0056] Add 50Kg of ceramic fiber, 70Kg of 30% silica sol, 20Kg of titanium dioxide, 2Kg of non-alkali chopped glass fiber, and 28Kg of sepiolite into the pulping tank in turn for pulping. Inject water into the slurry tank so that the slurry concentration is about 2% to 3%, and add 1Kg of polyaluminum chloride and polyacrylamide in turn for flocculation. Mix well and prepare to shape. A continuous Fourdrinier net is used to extract and filter the slurry. After a vacuum dehydration, the slurry is pressed into a wet billet of a certain thickness and density by a pressure roller, and then enters an oven for drying through a conveyor belt. After cutting, the ceramic fiber board is obtained. Adopt the method described in the present invention to carry out performance measurement to the ceramic fiberboard produced by this example, the result is as follows: thermal conductivity (1000 ℃ of hot surfaces) is 0.078W / (m K); Combustion performance is A 1 grade; heating permanent line chan...

Embodiment 2

[0058] Add 50Kg of ceramic fiber, 70Kg of 30% silica sol, 20Kg of zirconium silicate, 2Kg of alkali-free chopped glass fiber, and 28Kg of sepiolite into the pulping tank in turn for pulping. After the components are evenly dispersed, transfer to Inject water into the slurry mixing tank to make the slurry concentration about 2% to 3%, add polyaluminum chloride and polyacrylamide each 1Kg in turn for flocculation. Mix well and prepare to shape. Completely immerse the mold connected with the vacuum pump into the stirred slurry pool, and when the wet billet sucked and filtered in the mold reaches the required thickness, transfer the wet billet to the tray and then transport it to the drying room for drying. After cutting, the ceramic fiber board is obtained. Adopt the method described in the present invention to carry out performance measurement to the ceramic fiberboard produced by this example, the result is as follows: thermal conductivity (1000 ℃ of hot surfaces) is 0.078W / (m...

Abstract

The invention provides a ceramic fiber plate which is prepared from the following raw materials in parts by weight: 40-70 parts of aluminum silicate fibers, 5-30 parts of adsorbents, 20-80 parts of inorganic binding agents, 1-5 parts of reinforcing fibers, 1-3 parts of flocculants and 4000-10000 parts of water. The ceramic fiber plate contains no organic binding agent and can not generate the environmental protection problems of blackening, smoking, pungent smell and the like. The ceramic fiber plate provided by the invention can be obtained with no need of calcination through the matching use of the inorganic binding agents and the adsorbents, has the advantages of no embrittlement and good toughness, is high in compression strength through the matching use of the aluminum silicate fibers, the reinforcing fibers and the flocculants and is reduced in cost through no need of the calcination. An experimental result indicates that the ceramic fiber plate provided by the invention achieves the compression strength more than 0.25 MPa.

Description

technical field [0001] The invention relates to the technical field of fiber products, in particular to a ceramic fiber board and a preparation method thereof. Background technique [0002] Ceramic fiberboard is aluminum silicate fiberboard, which is a kind of refractory material. It maintains good mechanical strength even after heating. Compared with fiber blankets and felts, this product is a fiber insulation product with rigidity and support strength. In addition to the excellent performance of the corresponding loose ceramic fiber cotton, the ceramic fiberboard has excellent toughness and strength, and has excellent wind erosion resistance. It does not expand when heated, is light in weight, convenient in construction, and can be cut and bent at will. It is an ideal energy-saving material for kilns, pipelines and other insulation equipment. In the fields of ceramic wall-hung boilers and household appliances, in addition to the above-mentioned basic properties, heat ins...
