Description
Technical field
The invention belongs to fire resisting timber door field, and in particular to a kind of high-strength fire-retardant timber and its production method.
Background technology
Anti-fire door core board is a key raw material in Fireproof door structure, the quality of fire resistant doorsets performance, largely
On be decided by the performance and quality of door panel.But up to this point, the country is directed to the relevant criterion of anti-fire door core board still
Blank, manufacturing enterprise follow simply《Fire resistant doorsets GB12955-2008》In to several of fire resistant doorsets packing material descriptions, except material
Material must is fulfilled for flammability non-ignitable (A1 grades) and two mandatory conditions of flue gas toxity AQ1, and material needs to meet environmental requirement, made
With outside degradation material, this, which causes door panel to give birth to, is not provided to more materials and physical and chemical index, technic index clearly
There is larger operable space in production enterprise in product standard and quality control standard, cause in industry product it is very different,
Shoddy phenomenon generally existing.
At present, can substantially meet the door core material of fire resistant doorsets quality and manufacturing technique requirent mainly has following several：
First, expanded perlite sheet material, i.e., from Conventional insulation expanded perlite granule, by selecting suitably gluing
Agent, takes cold heat press high-pressure moulding process to be made, and by the adjustment of adhesive formulation and compression factor, can obtain good
Good heat-insulated and flashback performance, burning shrinkage rate and quality burn tinctuer are relatively low, are a kind of fire-resistant door core materials of better performances.But by
High in raw material cost of transportation, supply is limited, in addition complex manufacturing, is difficult to realize mechanization and pile line operation,
Production capacity is low, therefore in addition to some northern areas, most fire resistant doorsets enterprises are not widely used；
2nd, magnesite fire-proof door panel, magnesite material is a kind of low-carbon environment-friendly, environment-friendly inorganic material, and its is excellent
Material property and processing characteristics make it be had a wide range of applications in building materials field, include Dai Mu, Dai Shi of rising in recent years
The industry such as decoration and environmental type building, none be not using magnesite is high-strength, fire resisting, corrosion resistant, anti-mould and anti-moth, easy processing,
It is pollution-free to wait good characteristic.Magnesite material adds chemically or physically foaming agent and produces microvesicle, by mould or concora crush moulding process,
The light weight board of all size variable thickness is can be made into, density can reach fire resistant doorsets quality in 290~450 kilograms/cubic metre
And application requirement, domestic majority fire resistant doorsets manufacturing enterprises are used as fire-resistant door core material from it.Magnesite fire-proof door panel former material
Expect abundance, cheap, technology is relatively easily grasped, can be by mechanization production line balance, energy production potential is big,
Produce integrated cost low, be the door core material of a kind of more most market prospects and competitiveness.But magnesite is appeared in for a long time
Quality problem on foaming door panel is concentrated mainly on the following aspects：(1) return halogen to get damp, corrosion door-plate；(2) plate body powder
Change, argillization, intensity deficiency decay；(3) water imbibition is strong, eats glue seriously, causes to be increased with glue cost, or even door-plate degumming sky occurs
Drum；(4) fire resistance is poor, and core quality burn tinctuer is too high, causes fire resistant doorsets to be examined and does not reach the requirement of fire resisting time limit；Also deposit in addition
Specification deviation, flatness deviation is excessive the problems such as.
The content of the invention
For problems of the prior art, the invention provides a kind of high-strength fire-retardant timber and its production method,
The production method of this kind of fire resisting timber door is simple and convenient, consumes energy low, and pollution is few, and this kind of fire resisting timber door be not hygroscopic, is not likely to produce powder
