Description
Technical field
The present invention relates to fire-retardant partition wall, and in particular, to the preparation method of the fire-retardant partition wall of space lease.
Background technology
With the development of economy and society, the quickening of life and work rhythm, most of Administrative Areas are no longer fixed reinforcing bars
The house of concrete, is more the working space split in a building, these spaces are rented in the form of lease
To target customer.Since the personnel often accommodated in these spaces are very much, fire-retardant fireproof is most important to lease space
It is required that.Common anti-flaming smoke-inhibiting agent has aluminium hydroxide, cerium hydroxide, magnesium hydroxide, halogen system anti-flaming smoke-inhibiting agent, phosphinates and gathers
Cyanamide etc., although the halogen system anti-flaming smoke-inhibiting agent that generally uses still use extensively now, the problems such as producing bioxin because burning
And the meeting after fire produces the reasons such as poison gas, its harm to human health and environment is increasingly closed be subject to people
Note.At present, and phosphinates has that dosage is few, the advantages that smoke density is low, no environmental hazard, have been to be concerned by more and more people.
But disclosed in patent document US 2007/0029532, phosphonate may cause to decompose in process, and process
During can produce frangible unavailable material, therefore, limit application of the phosphonate as anti-flaming smoke-inhibiting agent.
Patent document CN107207779A, it is entitled：The flame-retardant polymer of phosphorus compound and melam comprising heat treatment
Composition discloses, by will heat the anti-flaming smoke-inhibiting agent of some phosphonates acquisitions at a temperature of 200 DEG C or higher and be used as
The melam or melam derivative of retardant synergist are attached to polymer and can be easily worked under some harsh conditions.But
Because melam or melam derivative are not readily synthesized, increase the anti-flaming smoke-inhibiting agent application cost of addition melam.
Therefore, how a kind of anti-flaming smoke-inhibiting agent and plate containing such anti-flaming smoke-inhibiting agent or partition wall are provided and is ensureing it
On the basis of the advantages that smoke density is low, no environmental hazard, the production cost of material is reduced, it is fire-retardant in application material to improve it
Performance, and do not produce fragile materials, will not reduce the influence to main material matrix mechanical performance particularly toughness, be at present urgently
The technical problem of solution.
