Description
Technical field
The invention belongs to the field of building materials, and in particular to a kind of chlorine oxygen magnesium anti-fire door core board and preparation method thereof and the chlorine
The application of oxygen magnesium anti-fire door core board.
Background technique
Densely populated with social development, high building Cong Li, construction material, which is prevented fires, is related to the life of many people, seeks object
The problem of inexpensive fireproof and heat-insulating material of U.S. is always the concern of building materials circle.Fire resistant doorsets are the important links in numerous fire prevention links
One of, anti-fire door core board is then that fire resistant doorsets fireproof is crucial.
Anti-fire door core board mainly has a two major classes at present, and one kind is organic insulation material, such as XPS, PVC, PUR, PE, EPS,
Since its smoke amount and cigarette poison after burning may bring bigger fire hazard, fire disaster in recent years endangers, and has him
Figure, be gradually eliminated.Another kind of is inorganic fireproof material, such as rock wool, mineral wool, asbestos, perlite, vermiculite, micro-
Hole calcium silicates, foam glass etc..The materials self-strength such as rock wool, mineral wool, asbestos is poor, needs skeletal support, and skeleton again can band
Carry out new fire prevention smoke virus problem, and flue gas toxity index is unqualified, has been prohibited from using at present.The fire resistings such as perlite, vermiculite
Degree is not high, and hygroscopicity is big.The production energy consumptions such as microporous calcium silicate, foam glass are high, and product price is high.And use lightweight magnesite
Material anti-fire door core board, self-strength is high, does not have to skeletal support, simplifies the manufacturing process of fire resistant doorsets, improves production efficiency, reduces
Production cost；Its production process three-waste free discharge, it is environmentally protective；Maintenance does not need additional energy, saves to spontaneously dry solidification
Energy；Cigarette poison test of burning is AQ1Grade, fire endurance can arrive 2h, and safety has been widely accepted as anti-fire door core board.But
It is there is also certain problem, containing largely free chloride ion in underproof magnesite product composition, in the environment of hot humid
Under, there is " returning halogen " phenomenon, corrodes the frame material of fire resistant doorsets and greatly shorten the service phases of fire resistant doorsets in the easily generation moisture absorption
Limit.Additionally due to magnesite material preparation production lack of standardization, the build-in attribute of conventional formulation, production fire resistant doorsets fire resisting when
Between have a greatly reduced quality, the big more options of enterprise increase density and thickness, and to meet fire resistant requirements, the increase of door panel quality, cost increases
Greatly, while again it will cause other accessory requirements of fire resistant doorsets increase, cost greatly increases.In addition, making a general survey of the fire resistant doorsets of domestic production
Core plate flexural strength is low, fire protecting performance is poor, and structure is easily collapsed during high temperature baking.
Summary of the invention
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, provide a kind of chlorine oxygen magnesium anti-fire door core board and
Preparation method and its application, to solve existing chlorine oxygen magnesium anti-fire door core board in the presence of there is also the moisture absorption, fire protecting performance are poor and anti-
The technical issues of structure is easily collapsed during folding intensity low and high temperature baking.
In order to achieve the above-mentioned object of the invention, an aspect of of the present present invention provides a kind of chlorine oxygen magnesium anti-fire door core board.The chlorine
