Description
Technical field
The invention belongs to technical field of macromolecules, specifically a kind of thermoplastic polyester elastomer fire-retardant combination and its preparation
Method.
Background technique
Thermoplastic polyester elastomer (TPEE) is the linear multiblock of a kind of polyester hard section and aliphatic polyester or polyester soft segment
Copolymer, had both rubber elasticity and thermoplastic processable characteristic, be widely used in wire and cable, household electrical appliance,
The fields such as auto manufacturing, medical treatment.Flame retardant property as thermoplastic elastomer (TPE) an important indicator and be concerned, have it is excellent
The thermoplastic polyester elastomer of different flame retardant property is widely studied.In existing research have numerous studies be with halogenated flame retardant into
Row TPEE is flame-retardant modified, however its feature of environmental protection is poor, thus developing halogen-free flame retardants it is flame-retardant modified to carry out TPEE is inexorable trend, phosphorus
Flame retardant due to its low toxicity, low cigarette, flame retarding efficiency is high and is widely used in all kinds of synthetic materials, based on phosphorus flame retardant
The expansion type flame retardant for wanting component is a kind of composite flame-retardant agent that multielement cooperates with, the spy high with flame retarding efficiency, additive amount is few
Point, the flame retardance of polymer especially suitable for anaerobic or few oxygen are modified.
German Clariant company is dedicated to the research of this novel phosphorus flame retardant, finds phosphinates and with phosphinates
Based on fire retardant can be used for thermoplastic, such as PA (polyamide, polyamide), PBT (polybutylene
Terephthalate, polybutylene terephthalate (PBT)), fiber and textile it is fire-retardant, especially containing oxygen element and nitrogen member
There is excellent flame retardant property in the presence of the polymeric system of element.German patent DE-A-4430932 discloses dialkyl phosphinic acid
The preparation of alkali metal salt/thermoplastic polyester fire proofing, used in dialkylphosphinic salts be mainly diethyl phosphinic acids
Aluminium, when fire retardant additive amount is 30%, material has preferable flame retardant property.German patent DE-A-2447727 discloses benefit
With the metal alkyl phosphinates of Section II main group and Section III main group, Flameproof polyamide moulding article is prepared.In above-mentioned patent
In the fire-retardant polymerization system of alkyl phosphinate, need to add containing nitrogen compound as synergist, dialkylphosphinic salts are containing
Its fire retardation could be effectively played in the presence of nitrogen compound (such as melamine), these are containing nitrogen compound with individual group
Divide together with alkyl phosphinate, be added by way of blending, and additional amount is also bigger, these nitrogenous synergists are added
After be difficult to be uniformly dispersed, the poor compatibility with synthetic material and between fire retardant deteriorates the mechanical performance of material, fire-retardant effect
Rate can not give full play to, and furthermore also make troubles the process of composite material.

It is and existing in conclusion the fire retardant in composition provided by the invention is a kind of novel efficient halogen-free anti-inflaming agent
The structure of some dialkyl phosphinic acids, dialkyl phosphinic acid ester and dialkyl metal phosphinate based flame retardant is different, due to
Introduced in alkyl it is nitrogenous and containing ester group, it can be achieved that unimolecule expandable flame retardant, and additive amount is few, flame retarding efficiency is high.
In addition, thermoplastic polyester elastomer (TPEE) fire-retardant combination of the invention during the preparation process, can be according to difference
Different additives is targetedly added in fire-retardant combination and is modified for purposes, such as inorganic or organic filler.
Unspecified content is the prior art known to a person of ordinary skill in the art in this specification.
Above-described specific embodiment is only schematical, and used technical term is limited in the present invention
Qualifier is only for convenience of description of the invention, and those skilled in the art are at fire-retardant group of thermoplastic polyester elastomer of the present invention
Under the enlightenment for closing object and preparation method thereof, without breaking away from the scope protected by the purposes and claims of the present invention, may be used also
Many forms are derived, these are within the scope of the present invention.
