Description
Technical field
The invention belongs to the synthetic preparation field of fire retardant, relate to a kind of novel halogen-free environment-friendly flame-proof agent, be specifically related to a kind of organosilyl phosphorus-nitrogen containing flame retardant that contains, particularly the preparation method of this fire retardant.
Background technology
Current macromolecular material has been widely used in every field, so the fire-retardant research of macromolecular material has become a research direction of field of materials.Though traditional halogenated flame retardant flame retardant effect is good, can produce a large amount of smog and toxic gas when meeting fire burns, threaten people's life security.The enhancing of Along with people's environmental protection, awareness of safety, the low cigarette of exploitation, nontoxic halogen-free flame retardants become a focus of current flame retardant area.Halogen-free expansion fire retardant (IFR) has become an important development direction of current fire retardant material because of having the high and low cigarette of flame retarding efficiency, characteristics such as nontoxic.IFR is main nucleus with P, N, C, receiving highly can to produce P-N cooperative flame retardant effect when hot, generates the carbonaceous foam layer of even compact, has heat insulation, oxygen barrier, presses down the effect of cigarette, anti-molten drop, performance good flame performance.Usually composite with ammonium polyphosphate (APP), trimeric cyanamide (MEL) and tetramethylolmethane (PER) as IFR.Owing to be rich in NH among the IFR
4 +,-NH
2,-hydrophilic radicals such as OH, the moisture absorption is poor with the macromolecule matrix consistency easily, is prone to migration precipitation, so will carry out surface modification treatment usually.The general consistency that adopts micro encapsulation or coupling agent surface-treated can improve IFR and polymer base material.
Melamine cyanurate (MCA) be last century the eighties by the U.S. and day the present invention's a kind of lubricant and fire retardant, nylon fire-retardant had special efficacy.MCA can with the composite use of other fire retardant, have the good flame effect.But because MCA is rich in hydrophilic radical, the moisture absorption very easily.
Organic silicon fibre retardant has efficient, nontoxic, smokeless, no molten drop, advantage such as pollution-free also are that a kind of one-tenth charcoal presses down fumicants, with phosphorus, the composite use of nitrogen based flame retardant, can bring into play good cooperative flame retardant effect.In addition, can also improve the mechanical property and the processing characteristics of flame retarded polymeric material.But because price is more expensive, it is still not extensive to apply face.
Summary of the invention
The invention provides a kind of organosilyl phosphorus, nitrogen flame retardant and preparation method of containing.The present invention combines organosilicon, P contained compound and nitrogen flame retardant, collects nitrogen, phosphorus, three kinds of elements of silicon in a part, can better bring into play the cooperative flame retardant effect.Owing on the nitrogen flame retardant, introduced organosilicon; Has good hydrophobic performance; Strengthened the consistency of this fire retardant and polymer base material greatly; Make fire retardant be difficult for producing the migration precipitation phenomenon, make macromolecular material obtain persistent flame retardant properties, can also improve the mechanical mechanics property and the processing characteristics of flame retarded polymeric material.This fire retardant both can use separately, also can with the composite use of other halogen-free flame retardantss, can be widely used in the fire-retardant of macromolecular materials such as nylon, rubber, urethane, polyolefine.
