Description
Technical field
The present invention relates to fire resistant doorsets field of material technology, and in particular to a kind of high temperature resistance and high strength fire-resistant door core sheet material and its
Preparation method.
Background technology
At present, with the development of national real estate industry, the demand of fire-proof construction material is more and more wider, it is desirable to also increasingly
It is high.Fire resistant doorsets have multi-functional and the practicality such as closing, back-fire relief, cut-off, safety, insulation, sound insulation, as Building Fire Protection system
In important part, and increasingly paid much attention to by national construction sector and NFA general bureau.Fire resistant doorsets are implemented
License granting mechanisms, production fire resistant doorsets must obtain the production licence that NFA general bureau issues, and fire-resistant door core sheet material is anti-
The indispensable core material of vent, needs to obtain the formal testing of relevant departments, to fire resistant doorsets in combustibility and security performance
The production of coreboard proposes higher condition.
Due to the fire-resistance property of magnesia, so it is fashionable for a time to produce anti-fire door core board with magnesia oxychloride cement.But because of technology
Level is uneven, and the problem of magnesia oxychloride cement anti-fire door core board occurs in that such or such in a particular application, such as steel are prevented
Vent corrosion, fire resistant doorsets come unglued, fire resistant doorsets occur cavity, door panel intensity difference, it is scaling-off fall grey, the easy moisture absorption make fire-proof wooden door
The problems such as deformation.Especially steel-made fire-retardant door corrosion problem is brought massive losses to unit in charge of construction and developer, given than more prominent
Society causes great waste, and its negative effect is far longer than the economic benefit of the product.Therefore, many fire resistant doorsets manufacturers open
Begin to find the fire resistant doorsets door panel product for substituting magnesia oxychloride cement.Such as waterglass perlite platelet, rock cotton board anti-fire door core board
Product, but there is low production efficiency, high-grade flower-shape fire resistant doorsets in fire resistant doorsets production process and can not produce in these door panel products
The problem of.Production efficiency be lowly because waterglass perlite can only produce at present in platelet, fire resistant doorsets production process can only be by
Platelet splices.In addition, rock cotton board is not environment-friendly products, rock wool ash is produced after the aging of product harmful.Especially because of it
The problem of material, can not meet the bonding of the high-grade fire resistant doorsets with flower-shape.The quality of fire resistant doorsets fire resistance, is mainly reflected in
In the selection of fire-resistant door core material.Magnesite fireproof plate, expanded vermiculite plate, foamed cement board, expanded pearlite rock beam etc. are all important
Fire-resistant door core sheet material.But there are some problems in these anti-fire door core boards, such as in actual applications：Magnesite fire-proof door panel is deposited
Got damp returning halogen, the problem of corroding door-plate；Expanded vermiculite plate and expanded pearlite rock beam, which have poor toughness, frangible and unit weight is big etc. asks
Topic；There is hygroscopic, frangible and fire resistance in foamed cement board.
In summary, prevent can not find the preferable door panel material product that disclosure satisfy that fire resistant doorsets producer in market at present.
The content of the invention
, should it is an object of the invention to provide a kind of high temperature resistance and high strength fire-resistant door core sheet material for the defect of prior art
Fire-resistant door core sheet material has preferable high temperature resistant and fire protecting performance, and its heat-insulated and barrier fire smoke performance is stronger, resistance to compression, anti-
Folding etc. mechanical performance index preferably, the environmental protection of door panel material, high-strength light, reached fire prevention flammability and security will
Ask；The raw material components of the present invention are safe and reliable simultaneously, environmental sound and raw material is easy to get, and cost is relatively low, technique is concise, be easy to grasp
