Description
One, technical field
The invention belongs to refractory and drip the technical field that additive and fire retardant and preparation method thereof reach purposes, specifically, it is remarkable especially that the present invention is that a kind of refractory drips effect, also has fire retardation simultaneously, the alternative existing additive flame retardant that is used for polyester etc., the preparation method of the especially non-halogen polymer-type additive of Halogen additive flame retardant, and this additive and its are used for polyester and the polyamide polymers refractory drips and fire-retardant purposes.
Two, background technology
Existing most polymers, as polyester, polymeric amide etc., do not possess flame retardant resistance, but expansion along with its Application Areas, in some special use occasion, finishing material or the used aspects such as protective clothing of special industry as aviation, public place of entertainment, family etc., then require it to reach certain fire-retardant requirement, otherwise will improve the insecurity of fire greatly.Moreover, these polymkeric substance also can drip under burning or high temperature in fusion, thereby have limited them and taken the fiber use in the use, particularly conduct of some occasion.Because when running into fire, the polymer melt drippage not only can make the people scald, and also may cause new fire because of other material that ignites behind the molten drop drippage.
In order to make high molecular polymer possess non-flame properties, it carry out fire-retardantization with regard to needing.At present macromolecular material is carried out fire-retardantization two kinds of methods are roughly arranged: the one, copolymerization is flame-retardant modified, is about to fire-retardant monomer with the polymer monomer copolymerization.The 2nd, add the fire retardant modification.But adopt the sort of mode carry out fire-retardantization no matter be, the research emphasis of prior art all is the fire-retardant aspect that is placed on polymkeric substance, and pay close attention to very few to the dripping property of refractory of polymkeric substance, this makes the great majority all very high flame-retardant polymer of limiting oxygen index determination method evaluation, its dripping property of refractory is all very poor, as the clear 47-32299 of Japanese Patent disclosed " fire-retardantization polyester synthetics ", German patent DE-OS 2438967, DE-OS 2253207, the disclosed respectively flame retardant polyester setting composition that contains the macromolecule organic phosphine compound of DE-OS 213235, contain the flame retardant thermoplastic polyester resin of diaryl-phosphide and the fire-retardant poly terephthalic acid propane of phosphorated ester additive etc., all can not satisfy simultaneously refractory is dripped and fire-retardant service requirements.
Three, summary of the invention
The objective of the invention is defective, provide a kind of refractory to drip and fire-retardant non-halogen polymer-type additive at the prior art existence.Another object of the present invention provides the preparation refractory and drips method with fire-retardant non-halogen polymer-type additive.Last purpose of the present invention provides the purposes of this additive.
Refractory provided by the invention drips and fire-retardant non-halogen polymer-type additive, and the feature that is showed is to have following repeated structural unit:
