Abstract
The invention discloses a preparation method and application of flame-retardant polyether. The flame-retardant polyether contains N, P and Br elements and is reactive flame-retardant polyether. According to the preparation method, the flame-retardant polyether is prepared from the following raw materials in parts by weight: 5-10 parts of ethylenediamine, 20-30 parts of tri(3-hydroxypropyl)phosphine, 23-28 parts of dibromoneopentyl glycol, 0.5-2.0 parts of dimethylamine and 30-51.5 parts of epoxy propane. Polyurethane foaming plastics prepared from the flame-retardant polyether have a favorable flame-retardant effect and have the advantages of stable flame retardance and better foam quality as comparison with polyurethane foaming plastics prepared by additionally adding a flame retardant.
Description
Technical field
The invention belongs to the preparation method of organic high molecular compound, specifically a kind of preparation method of polyurethane foam flame retarding polyether and the application of obtained product.
Background technology
Conventional polyurethanes porous plastics is inflammable material, for reaching flame-retardancy requirements, usually adds fire retardant when preparing urethane foam.But polyurethane material quality prepared by additional fire retardant is affected, and have effusion along with passing additional type fire retardant duration of service, flame retardant effect worse and worse.
Summary of the invention
In order to overcome prior art Problems existing, the object of this invention is to provide a kind of preparation method of flame retarding polyether and the application of obtained product, the urethane foam adopting this flame retarding polyether to prepare has good flame retardant effect, the urethane foam flame retardant properties prepared relative to additional fire retardant is stablized, and froth quality is better.
The object of the invention is to be achieved through the following technical solutions:
A preparation method for flame retarding polyether, is characterized in that: with quadrol, three (3-hydroxypropyl) phosphine, dibromoneopentyl glycol altogether for initiator; Dimethylamine is catalyzer; Prepare with propylene oxide ring-opening polymerization, obtain flame retarding polyether, comprise the steps:
1) raw material weight number is: quadrol 5-10; Three (3-hydroxypropyl) phosphine 20-30; Dibromoneopentyl glycol 23-28; Dimethylamine 0.5-2.0; Propylene oxide 30-51.5;
2) quadrol, three (3-hydroxypropyl) phosphine, dibromoneopentyl glycol are put in reactor, drop into dimethylamine again, then at 80-130 DEG C of temperature, pass into propylene oxide, after propylene oxide adds end, stir 1-3 hour under remaining on 80-130 DEG C of temperature, system is fully reacted;
3) vacuumize, filter and obtain flame retarding polyether.
In the present invention, described dimethylamine to be mass percent be 40% dimethylamine agueous solution.
The application of flame retarding polyether in polyurethane foam that a kind of preparation method of flame retarding polyether obtains.The polyurethane foam quality prepared with it is good, flame retardant effect obviously and foam flame retardant properties can not As time goes on be deteriorated.
Containing N, P, Br element on flame retarding polyether molecule prepared by the present invention, have cooperative flame retardant effect, the polyurethane foam quality prepared with it is good, flame retardant effect obviously and foam flame retardant properties can not As time goes on be deteriorated.
