Abstract
The invention relates to a fire-proof board used for antique buildings, belongs to the field of refractory materials, and aims to solve the technical problems in the prior art that the noxious fumes are released when the fire-proof board is fired, the density is large, the production material of the fire-proof board has strong danger and the accident threat for safety in production exists and so on. The fire-proof board used for antique buildings contains the following components by weight part: 18-24 parts of calcined magnesium oxide, 7-15 part of industrial magnesium chloride, 3-6 parts of glass fibers, 35-60 parts of light-weight fillers, 1-2 parts of modifiers and 20-35 parts of water. The light-weight fillers are a mixture of any one, or two of expanded perlite and expanded vermiculite at any proportion. The fire-proof board is suitable for fire protection of antique buildings.
Description
Technical field
The present invention relates to fire resisting material field, especially for PLASTIC LAMINATED of ancient building and preparation method thereof.
Background technology
The Chinese nation's historical civilization in 5000 has bred magnificent Chinese culture, and each dynasty carries over a large amount of various ancient buildings in history.These ancient buildings have very high spiritual value, cultureal value and practical value.Therefore, strengthen ancient building protection, guarantee the safety of ancient building, its meaning is very great.
The numerous ancient building of China adopts timber and timber structure more, and fire load density is big, and Hong combustion takes place easily, add in the heritage buildings, many, the difficulty of putting out a fire to save life and property of factor on fire, most again not fire prevention are cut apart, therefore, in case the ancient building presence of fire often causes serious consequence.
The flameproof protection of ancient building is extremely urgent major issue.In recent years, along with development of science and technology, various novel fire-proof construction materials and security against fire technology are constantly progressive, provide possibility for carrying out Fire protection with historic buildings protection work better.Yet; a lot of ancient buildings have historical relic character; according to " People's Republic of China's Law For the Preservation of Antiques " and " People's Republic of China's Law For the Preservation of Antiques implementing regulations "; security against fire protection work also must be followed the principle that does not change the historical relic original state; particularly; be exactly " four preserve " principle in the n protection, promptly preserve original shape system, primary structure, starting material, former technology.
In the case, PLASTIC LAMINATED comes into one's own day by day as ideal ancient building flameproof protection solution and pays close attention to, yet, in present miscellaneous PLASTIC LAMINATED, be not specially adapted for the PLASTIC LAMINATED of conservation of historic buildings.If any PLASTIC LAMINATED density big, can increase the load of ancient building; The combustionproperty that has is poor, can not play effective flameproof protection effect; Have in the scene of a fire, be subjected to fire the time can discharge a large amount of poison gas, can damage inhabitation personnel in ancient building or fire control and disaster rescue personnel, or the like.
Summary of the invention
The present invention be intended to solve existing PLASTIC LAMINATED density is big, fire performance is poor, intensity is low and can discharge when being subjected to fire poison gas, PLASTIC LAMINATED raw materials for production have strong dangerous and have the technical problems such as accident potential of safety in production, so that a kind of PLASTIC LAMINATED that is specially adapted for conservation of historic buildings to be provided.
The objective of the invention is to be achieved through the following technical solutions.
Fireproof plate for heritage building of the present invention, form by the raw material of following weight part:
Aforementioned light filler is any one in pearlstone and the expanded vermiculite, or the mixture of the two arbitrary proportion.
Fireproof plate for heritage building of the present invention, wherein said glass fibre are alkali-free or medium-alkali glass fibre.
Fireproof plate for heritage building of the present invention, wherein said properties-correcting agent are any one in SODIUM PHOSPHATE, MONOBASIC and the ferrous sulfate, or the mixture of the two arbitrary proportion.
The mechanism of action of the present invention: by light calcined magnesia, industrial hex-ammoniate and water modulation and with the gelling material of glass fibre enhanced in the inorganic coagulation material category, its intensity and toughness all are best, and have outstanding fire resistance.As the pearlstone of light filler and expanded vermiculite all is inorganic fire proof material efficiently, their adding, and one can reduce the density of PLASTIC LAMINATED, and can improve the fire performance of sheet material.Properties-correcting agent can improve water resistance, surface halide accumulation resistance and the toughness of sheet material.Whole sheet material system is made up of inorganic materials, can not discharge poison gas when being subjected to fire in the scene of a fire.
Below in conjunction with embodiment 1-5 (the concrete material proportion of each embodiment sees Table 2) technical scheme of the present invention is described further.
Fireproof plate for heritage building of the present invention, its density, combustionproperty etc. detect by GA160-2004 " fireproof inorganic composition board " that (fireproof plate for heritage building of the present invention can be by actual needs, and its thickness is between 3～70mm.For ease of explanation, the sheet metal thickness of embodiment 1-5 is 10mm), it produces the smoke toxicity classification and detects by GB/T 20285-2006 " classification of material producing smoke toxicity risk ", and its main performance index sees Table 1.
Table 1 fireproof plate for heritage building main performance index
Annotate: sheet material is divided into some classes by the difference of density, and each class is pressed the thickness difference, and its performance is had different requirements.
In sum, fireproof plate for heritage building of the present invention and preparation method thereof has following technical characterstic and beneficial effect:
1. density is little, intensity is big;
2. combustionproperty does not reach the combustion level;
3. can not discharge poison gas when in the scene of a fire, being subjected to fire;
4. applicable to the flameproof protection of ancient building.
Embodiment
Each embodiment components by weight portions of fireproof plate for heritage building of the present invention is as shown in table 2.
Table 2 embodiment material proportion table
| ? | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 |
| Light calcined magnesia | 20 | 22 | 24 | 19 | 18 |
| Industrial hex-ammoniate | 11 | 15 | 13 | 7 | 9 |
| Light filler | 54 | 35 | 60 | 40 | 48 |
| Glass fibre | 3 | 6 | 5 | 4 | 4.5 |
| Properties-correcting agent | 2 | 1.2 | 1 | 1.8 | 1.5 |
| Water | 35 | 27 | 23 | 20 | 32 |
The preparation method of each embodiment is identical, promptly press the consumption of table 2, to pour in the agitator kettle behind the pre-mix of light calcined magnesia, light filler and glass fibre earlier, the magnesium chloride solution that adding prepares begins to stir and the even properties-correcting agent that adds in whipping process, mix and stir the discharging and the in-mold molding of packing into behind the 1-5min, solidify the back form removal, dry maintenance.During small-scale production, available hand is stuck with paste technological forming; During scale operation, available machinery vibrates, compression moulding.
From the above; fireproof plate for heritage building of the present invention and preparation method thereof; can significantly improve the fire resistance of finished product PLASTIC LAMINATED, have simultaneously that density is little, intensity is big, be subjected to fire can not discharge characteristics such as poison gas in the scene of a fire, thereby can reach the purpose that is exclusively used in the ancient building flameproof protection.
