Abstract
The present invention relates to polyether polyhydric alcohol of a fire retardant polymer, and a preparation method of the polyether polyhydric alcohol for a massive fire retardant polyurethane soft bubble. Universal polyether polyhydric alcohol is used as a continuous phase, and a subnanometer ultramicro polymer particle of the amidocyanogen diisocyanate modified polyether polyhydric alcohol (a dispersing agent) of a surface grafting part is used as a dispersed phase, and a stable polymer colloidal dispersed system which is composed of the continuous phase and the dispersed phase forms the polyether polyhydric alcohol of a fire retardant polymer. Formaldehyde, urea, melamine and hexamethylenetetramine are used by the present invention to react for 0.5 to 4 hours in polyether polyhydric alcohol at 65 DEG C and 98 DEG C under the existence of the dispersing agent, and the polyether polyhydric alcohol of a fire retardant polymer is prepared by drying. The polyether polyhydric alcohol of a fire retardant polymer does not contain the toxic and harmful substances of phosphorus, halogen, styrene, acrylonitrile, etc., and has the characteristics of simple preparation process, low cost, easy foaming, etc. The obtained polyether polyhydric alcohol of a fire retardant polymer, universal polyether polyhydric alcohol and a diisocyanate compound are prepared into fire retardant polyurethane foam by massive foaming technology under the existence of trialkylamine, an organic metallic catalyst, water, a physical foamer and a small amount of silicon oil foam stabilizer. The material of the fire retardant polyurethane foam has high fire retardance (an oxygen value number can reach 28%); meanwhile, the material of the fire retardant polyurethane foam has high mechanical properties and indentation hardness.
Description
Technical field
The invention belongs to polyether polyol and preparation Application Areas thereof, be specifically related to a kind of flame-retardant polymer polyether glycol and be used to prepare the method for block resistance combustion polyurethane foam material.
Background technology
Polyurethane foamed material is a kind of superpolymer with special performance and many-sided purposes.It is a basic raw material with polyether glycol and diisocyanate, allocate less water, organic silicon surfactant, whipping agent into, under the acting in conjunction of organotin and tertiary amine catalyst, form, can make hard, semi-rigid and flexible urethane foam with it, be applied to the aspects such as saddle of cushion, back cushion, inside gadget and the motorcycle of vehicle mainly as cushioning material, also can be used for making simultaneously the products for civilian use such as sofa, mattress, finishing material.
Polyether polyol normally, vinyl monomer in the presence of dispersion agent in polyether glycol the diffuse-aggregate product of free radical, the used vinyl monomer of polyether polyol at the beginning of the seventies is a vinyl cyanide, its solid content (polymer content) is 5%~25%, viscosity height, look Huang, easily makes the heartburn variable color of polyurethane foam; The mid-80 prepares polyether polyol with vinyl cyanide and vinylbenzene mix monomer, and its solid content is 20%~30%, and styrene content is more than 50%; At the initial stage nineties, abroad some companies release one after another solid content more than 40%, and viscosity is lower than the polyether polyol of 5500mPas (25 ℃), as European patent Eur.Pat.Ep778,301; PCT.Int.Appl.Wo.97,15,605; PCT.Int.Appl.Wo.97,15,606 disclosed polyether polyols, but these polyether polyols all do not have flame retardant resistance, do not have flame retardant resistance with its prepared polyurethane foam yet.
The urethane foam goods very easily burn, fire-retardant difficulty, and flame resistant method commonly used at present is to add fire retardant in the raw material of producing urethane mostly, used fire retardant mainly contains reaction-type flame-retarding polyether glycol and non-response type small molecules fire retardant; The reaction-type flame-retarding polyether glycol mainly is phosphorous chlorine polyether glycol, and is low with the prepared polyurethane foam cost of this polyether glycol height, bearing capacity; The kind of non-response type small molecules fire retardant mainly contains Sb
