And its production method.
Background technology
Calcium silicate board is a kind of common building and ornament materials, has been widely used the shifting board in ship, furred ceiling
With the wall of building non-bearing, and there are other places of fire protection requirement.Due to there is asbestos in traditional asbestos silicic acid cover plate,
Harm is brought to health, easily triggers cancer, asbestos friction material was gradually disabled in recent years, technical staff transfers to seek more preferably
Substitute to be met the asbestos-free calcium silicate board of requirement.
At present, the existing document report of the preparation method of asbestos-free calcium silicate board, such as Publication No. CN1884180A（It is a kind of
Asbestos-free calcium silicate board and preparation method thereof）And CN1205315 A（Non-asbest china clay calcium silicate plate and preparation method thereof）In
State's patent application, discloses the preparation method of asbestos-free calcium silicate board, but the preparation side of these existing asbestos-free calcium silicate boards
Method, which exists, to be disadvantageous in that：Due to needing to use substantial amounts of raw ore material and lignocellulose raw material, on the one hand it is caused to give birth to
Produce cost higher, on the other hand cause the consumption of ore resource, do not used effectively for the discarded object being widely present, discarded object
Recycling level of application it is low, the problems such as concurrently there are cost high, difficult construction and poor performance parameter.
China has been soda manufacture state maximum in the world at present, and the improvement of ammonia alkali factory alkaline residue is always that restriction is pure both at home and abroad
The bottleneck of alkali industry development.As National Environmental administers the sound of policies and regulations, the environmental requirement to soda in China enterprise enters one
Step improve, if from now on soda in China industry waste residue, the waste liquid of ammonia alkali enterprise discharge in order and comprehensive utilization in terms of still without
Breakthrough, by the sound development of serious restriction soda industry.Therefore, the comprehensive utilization of alkaline residue and its Treatment process are ground
Study carefully with far-reaching society and economic implications.Alkaline residue main component is CaCO3, NaCl, also includes a certain amount of silica,
Therefore, alkaline residue is innovatively applied in the preparation of calcium silicate board by the application.
The present invention is to utilize alkaline residue, bentonite, wollastonite, cement, diatomite to be base material, adds synthetic fibers and activation
The auxiliary materials such as agent, prepare asbestos-free calcium silicate board, take full advantage of the physical arrangement and wollastonite and cement mixing of the composition of alkaline residue
Aquation, and fiber the most suitable and activator are have selected, production is met the asbestos-free calcium silicate board of indices, realizes
Turn waste into wealth, improve that waste utilization efficiency, performance indications are superior, production cost is relatively low, environmental protection without asbestos silicic acid
Calcium plate.
The content of the invention
The present invention is that purpose is to expand the utilization approaches of alkaline residue, in order to improve waste utilization efficiency, obtains performance and refers to
The superior, production cost of mark is relatively low, environmental protection asbestos-free calcium silicate board.

10-20 parts, 15-20 parts of fibrous wollastonite, 15-25 parts of cement, above-mentioned raw materials are put into agitating device and are sufficiently stirred for, then
A certain amount of water is added, is stirred for, the compound after stirring is then subjected to shelving；2nd, the alkali resistant glass fibers of 3-5 parts of parts by weight are taken
Dimension, 5-8 parts of polypropylene chemical fiber, 0.5-3 parts of waterglass, 1-5 parts of anhydrous sodium sulfate and a certain amount of water, are filled
The mixing divided；3rd, the compound and step 2 obtained step 1 obtains compound and is put into mixer to stir, then will
Obtained compound is put into hydraulic press mould, and precuring is stripped after shaping, obtains the idiosome of precuring；4th, by step 3
In the obtained idiosome of precuring carry out steam press maintenance；5th, drying and processing is carried out after completing steam press maintenance, no asbestos alkaline residue is obtained
Calcium silicate board product.
It is an advantage of the invention that：
1st, the present invention is incorporated alkali resistant glass using alkaline residue, argillaceous bentonite, wollastonite, cement, diatomite as base material primary raw material
Glass fiber, polypropylene chemical fiber, waterglass and anhydrous sodium sulfate so that alkaline residue discarded object is fully utilized, proportioning
Silicon, calcium content and ratio in base material is more excellent, can fully react, and obtained calcium silicate board intensity is high, fire resistance is high, anti-folding is strong
Degree is strong.
2nd, alkaline residue is directly using the solid alkaline residue of alkali factory discharge, it is not necessary to specially treated, is directly used in manufacture calcium silicate board,
Production cost is low.Argillaceous bentonite, fibrous wollastonite make it that reaction is more abundant, and obtained calcium silicate board performance is more preferably.
3rd, sheet material can be improved as activator by adding waterglass as the reaction of flocculation aid acceleration of hydration, anhydrous sodium sulfate
Intensity in relatively low steam curing temperature, alkali resistant glass fiber and polypropylene chemical fiber proportion so that calcium silicate board
Performance is significantly increased.Manufacture out without asbestos alkaline residue calcium silicate board product, meet the indices requirement of national standard, have
Good economic and social benefit.
