Abstract
The invention relates to a new-type inflaming retarding material and a preparation method thereof. The inflaming retarding material comprises the following raw materials in parts by weight: 100 parts of polypropylene, 5-16 parts of modifier, 5-10 parts of compound flame retardant. The new-type inflaming retarding material has better fire resistance, can effectively lower the probability of occurrence of fire disasters, reduce the damages caused by fire disaster compared with other polypropylene plastic foam materials, and can prepare the inflaming retarding materials with different inflaming retarding performances through controlling the content of the compound flame retardant at the same foaming multiplying power.
Description
Technical field
The present invention relates to a kind of fire retardant material and preparation method thereof, relate in particular to a kind of novel flame redundant material and preparation method thereof.
Background technology
At present, existing EPP(Expanded polyproplene): the acrylic plastering foam material all is to control its flame retardant properties by expansion ratio, and all is by external import.These materials exist various problems in actual use, inflammable as little fire, long from fiery self-extinguishing time, produce the fusion dropping that causes secondary combustion easily etc. in the combustion processes, these all are that hidden danger has been buried in the generation of fire and the expansion of fire hazard.High price and easy aptitude to burn have limited the use of EPP material.
Summary of the invention
The present invention is directed to existing acrylic plastering foam material and exist various problems in actual use, inflammable as little fire, long from fiery self-extinguishing time, generation causes the fusion dropping of secondary combustion etc. easily in the combustion processes, these all are the deficiency that hidden danger has been buried in the expansion of the generation of fire and fire hazard, and a kind of novel flame redundant material and preparation method thereof is provided.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of novel flame redundant material comprises the raw material of following parts by weight: 100 parts polypropylene, 5 parts～16 parts properties-correcting agent and 5 parts～10 parts compound flame redundant.
The invention has the beneficial effects as follows: novel flame redundant material of the present invention has resistivity against fire preferably, compare with other acrylic plastering foam material, can effectively reduce the fire odds and reduce the harm that fire causes, and under same expansion ratio, can prepare fire retardant material with different flame retardant propertiess by the content of controlling compound flame redundant.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described properties-correcting agent is for comprising static inhibitor, compatilizer and nucleator.
Further, described static inhibitor is HDC103.
Further, described compatilizer is a maleic anhydride inoculated polypropylene.
Further, described nucleator is a substituted benzoic acid aluminium salt, and preferably, described substituted benzoic acid aluminium salt is MD-NA-28.
Further, described compound flame redundant comprises eight bromo ether and antimonous oxide.
Described eight bromo ether is good fire retardant, and it can control polyacrylic degradation production, in conjunction with monomer, plays flame retardant effect from gas phase and condensed phase, and to the almost not influence of polyacrylic mechanical property; Described antimonous oxide is the synergistic flame retardant of eight bromo ether, when the eight bromo ether usage quantity is identical, adds a certain amount of antimonous oxide, and polypropylene material can obtain better flame retardant properties.
Further, the weight ratio of described eight bromo ether and antimonous oxide is 1:1～3:1.
The present invention also provides a kind of technical scheme that solves the problems of the technologies described above as follows: a kind of preparation method of novel flame redundant material may further comprise the steps:
Step 10: the compound flame redundant of 100 parts polypropylene, 5 parts～16 parts properties-correcting agent and 5 parts～10 parts joined in the high mixer mix;
Step 20: make the mixture pore-forming of the polypropylene, properties-correcting agent and the compound flame redundant that mix promptly can be made into novel flame redundant material.
Further, described step 20 may further comprise the steps: the mixture of whipping agent and the polypropylene, properties-correcting agent and the compound flame redundant that mix is joined in the screw extrusion press jointly, carry out blend in 160 ℃～180 ℃ and extrude and can make novel flame redundant material.
Further, described step 20 may further comprise the steps: the mixture of the polypropylene, properties-correcting agent and the compound flame redundant that mix is joined in the screw extrusion press, carry out putting into the dipping still that whipping agent is housed again after blend is extruded in 160 ℃～180 ℃, can make novel flame redundant material.
Further, described whipping agent is butane, pentane or supercritical co.
