Description
Technical field
The present invention relates to flame-proof sheet material, and in particular, to space lease fire-retardant double sheets and preparation method thereof.
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 is provided and the plate containing such anti-flaming smoke-inhibiting agent is ensureing its smoke density
It is low, the advantages that no environmental hazard on the basis of, reduce the production cost of material, improve its fire resistance in application material,
And fragile materials are not produced, the influence to main material matrix mechanical performance particularly toughness will not be reduced, are urgently to be resolved hurrily at present
Technical problem.
The content of the invention
The object of the present invention is to provide a kind of space lease fire-retardant double sheets and preparation method thereof, which uses
Contain a kind of anti-flaming smoke-inhibiting agent in fire-retardant double sheets, which is keeping the smoke density of phosphinates low, no environment
On the basis of the advantages that endangering, its fire resistance in application material can be improved, and does not produce fragile materials, will not be reduced
Influence to main material matrix mechanical performance, also, it is adjuvant used more economical.
To achieve these goals, the present invention provides a kind of space lease preparation method of fire-retardant double sheets to include
First material and second material are subjected to coextrusion mold；Wherein, first material and second material contain anti-flaming smoke-inhibiting agent, its
In, high 20%-200% in the weight content ratio second material of anti-flaming smoke-inhibiting agent in first material；Wherein, anti-flaming smoke-inhibiting agent is logical
Cross and prepare alkyl phosphinate, tributyl tin and the trioctylphosphine as shown in formula (I) after 200-300 DEG C of also contacts
Obtain；Wherein, in formula (I)：R1For C1-C6 alkyl or phenyls；R2For C1-C6 alkyl or phenyls；M is metal, and n is from 1 to 4
Number so that Mn+It is metal cation, the electric charge of the cation is wherein assigned on n+ representations, and the number that n is 1 to 4.
The present invention also provides a kind of fire-retardant double sheets of space lease being prepared according to preparation method described previously.
The space lease of the present invention will not be lost with the anti-flaming smoke-inhibiting agent in fire-retardant double sheets in high temperature working processes
Fire resistance, does not find the generation of brittle material yet, good mechanical property in obtained fire-retardant double sheets, fire-retardant, environmental protection.This hair
Bright space lease can be used for partition space with fire-retardant double sheets, and the working space of lease is made, and will meet to rent at present significantly
Space rent to fire-retardant, environmentally friendly, durable requirement.And the present invention space lease of the invention with fire-retardant double sheets cost compared with
It is low, the cost of manufacture in lease space can be reduced indirectly, therefore, had highly application value.
Other features and advantages of the present invention will be described in detail in subsequent specific embodiment part.
