Abstract
The present invention relates to an inorganic noncombustible plate and an application thereof. The inorganic noncombustible plate is characterized in that the inorganic noncombustible plate is composed of 80 to 130 parts of light calcined magnesium oxide powder (the MgO content is more than or equal to 85%.), 30 to 60 parts of halogen sheets (the MgCl2 content is more than or equal to 46%.), 40 to 70 parts of water, 5 to 40 parts of pulverized fuel ashes, 10 to 30 parts of wood dust, 0 to 25 parts of expanded perlite (the grain diameter is from 1 to 5mm.), 0.1 to 5 parts of composite water-resistant additives, two layers of fiberglass grid cloth (50 to 200 g/m2 of medium alkali glass) and two layers of non-woven cloth (16 to 20 g/m2 of polypropylene fiber), wherein the composite water resistant additive is formed by compounding phosphate with sulfate, and the compounding ratio of the phosphate to the sulfate is 1: 9 to 9: 1; the pulverized coal ashes are used as addition agents. The prepared inorganic noncombustible plate has the advantages of light weight, high strength, heat insulation, fire retardation, sound insulation, no poison, no harm and mechanical processing, and can be widely used for partition walls, suspended ceiling plates, roof plates in dwelling houses which are changed into slopes from planes and steel structure fireproof plates.
Description
Technical field
The present invention relates to a kind of inorganic non-combustible plate and application thereof, belong to the magnesium gelatinous material field.
Background technology
Magnesia oxychloride cement have that sclerosis is fast, hardness is high, fireproof performance good and with advantages such as the mixed performance of many sound and thermal insulating materials is good, yet its solubility in water has but limited range of application widely.From the knowledge that accumulated as can be known, under the normal temperature the main aquation after the magnesia oxychloride cement sclerosis to produce crystalline substance be 5Mg (OH)
2MgCl
28H
2O (being called for short 5 phases) and 3Mg (OH)
2MgCl
28H
2O (being called for short 3 phases).Studies show that 5 is that magnesia oxychloride cement is solidified and produces the phase that intensity plays main contribution mutually, 5 phase crystal habits are mainly needle-like, long column shape, and intersect each other and connect to net structure.5 meet is converted into 3 phases, so should manage at MgO-MgCl yet under certain condition,
2-H
2In the O system, strict control proportioning suppresses 5 conversions of 3 phases in opposite directions as far as possible.
Based on above understanding, the patent of invention that has provides a kind of waterproof magnesia cement (CN1225344A); What have provides a kind of aerated light wall panel material, unit weight≤0.5g/cm
3(CN1263065A).More be the report of inorganic fire plate, reported a kind of inorganic fire plate as Shanghai sea-freight group, it is to be matrix with the inorganic material, adds different additives after, the employing special process is made, Main Ingredients and Appearance is MgO, MgCl
2And inorganic reinforcing fiber (sea-freight science and technology 1995 (8) 9.8-9); And for example " composite fireproof Baoli polywood laminate " (building materials newly draw skill 1995 (4) 17-19) of Shandong Building Material College's Materials Science and Engineering system development is by inorganic coagulation material, glass fiber, increases compound making such as steel, Admixture, and it is to be main cementitious material with the water chestnut hardship; Waterproof, the PLASTIC LAMINATED of the development of US 5767178 report U.S. pyrotite companies are made up of cellulosic material, magnesia oxychloride cement or magnesium oxysulfide concrete etc. for another example, can make floor, wallboard and other sheet material.
In sum, refractory slab of reporting in the prior art of being introduced or PLASTIC LAMINATED all are to contain fiber, it or be glass fiber or for inorganic reinforcing fiber or cellulosic material, though because the adding of fiber improves the intensity of fire-proof board, fire resistance greatly, its cost improves and complex manufacturing technology.And still do not have up to now and see that the report of making adulterant with flyash is arranged.
Summary of the invention
Widely-used fiber improves its intensity and anti-flammability in the prior art in order to overcome; the object of the present invention is to provide a kind of high performance inorganic non-combustible plate; but it not only has lightweight, heat insulation, sound insulation, nontoxic but also fire prevention machining; not only can be used as wall panel, ceiling board, sound barrier, and can be used for the roof panel in " flat-changed-into-sloping " project and the flameproof protection of steel work.
The objective of the invention is to implement by the following technical programs:
Specifically the consisting of of the inorganic non-combustible plate that provides (weight):
80～130 parts of light-magnesite powder (MgO content 〉=85%)
Halogen sheet (MgCl
2〉=46%) 30～60 part
40～70 parts in water
5～40 parts in flyash
10～30 parts of wood chips
Expanded perlite (1～5mm) 0～25 part of particle diameter
0.1～5 part of compound anti-water additive
Glass fiber reticular cloth (middle alkali glass, 50～200g/m
2) 2 layers
Nonwoven (polypropylene fibre, 16～20g/m
2) 2 layers
The present invention uses flyash as adulterant: and react with base material, form water-fast compound 5 around mutually, thereby make 5 to be difficult for being converted into 3 phases mutually.With wood chip and expanded perlite as inserts; Compound anti-water additive is the compound sulfate of phosphate, and compound ratio 1: 9～9: 1, described phosphate are a kind of in calcium dihydrogen phosphate, magnesium dihydrogen phosphate, aluminium dihydrogen phosphate, sodium dihydrogen phosphate or the zinc dihydrogen phosphate; Described sulfate is a kind of in aluminum sulfate, copper sulphate or the ferrous sulfate.
The fibrous material that uses in the glass fiber reticular cloth replacement prior art with middle alkali glass can reduce production costs greatly and simplify activities, can avoid fiber skewness problem, or for solving complicated technology or the equipment that glass evenly distributes and adopts, and according to need, the mesh-density of glass fiber reticular cloth can be regulated in quite wide scope, with the increase of products thickness, mesh-density can be from 50～200g/cm
2, increasing (seeing embodiment for details), grid cloth and nonwoven lay respectively at two surfaces of composite plate, play a supportive role.
The inorganic non-combustible plate that the present invention makes is applicable to furred ceiling, roof panel, partition wall and steel structure fireproof protection.The concrete roof panel that has been used for the international welfare center for children in Shanghai, partition wall and the furred ceiling of silver-colored mansion Nan Lou handed over by Pudong, the partition wall of ZSPD and Golden Bridge Japan Toshiba factory building, supporting project of the steel work of General Motors and middle good fortune mansion steel structure fireproof protection etc.Usually make furred ceiling thickness 3～6mm; Thickness 8～the 12mm of roof panel, partition wall; General 10～the 12mm of steel structure fireproof protection specifically decides on the actual requirement of engineering.
In a word; inorganic non-combustible plate provided by the invention (DF plate) has lightweight, high-strength, heat insulation, sound insulation, fire-retardant, nontoxic, durable in use (changes in temperature circulation 〉=25 times, not aliquation, flawless) but advantages such as machining; not only can be used as wall panel, ceiling board, sound barrier, ventilating duct, car and boat body decorative panel; and being applicable to roof panel and steel structure fireproof protection in dwelling house " flat-changed-into-sloping " project, application prospect is good.
