Abstract
The invention belongs to the technical field of inorganic hybridized polymer materials and particularly relates to inorganic hybridized propylene glycol etherified melamine resin and a preparation method thereof. The preparation method mainly includes steps: (1) etherification reaction, to be more specific, adding hexamethylol melamine and propylene glycol into a reactor, and performing thermal reaction to obtain tetra-etherified or penta-etherified melamine resin; (2) alkali neutralization; (3) hybridization reaction; (4) distillation for removing residual propylene glycol; (5) cooling and filtering to obtain a finished product. The inorganic hybridized propylene glycol etherified melamine resin prepared according to the method has advantages that by hybridization cross-linking reaction with inorganic hybrid compounds, high-temperature flame-retardant elements such as boron and stibium are added into propylene glycol amino resin generated finally, and accordingly high temperature resistance and flame retardation of the propylene glycol amino resin are improved, and the resin is mainly applied to preparation of combined polyether and paint.
Description
Technical field
The invention belongs to inorganic hybridization technical field of polymer materials, it is etherified three particularly to a kind of inorganic hybridization propylene glycol
Cymel with and preparation method thereof.
Background technology
Because amino resins have certain heat resistance, so in a lot of fields, including coating industry, furniture industry,
Polyurethane industries among others etc. have application.But, it is applied on the polyurethane material of high fire-retardance, its resistance to elevated temperatures still has necessarily
Gap.
Due to the special construction of polyurethane foam plastics molecule, determine its easily burning, characteristic of non-refractory.With
Polyurethane energy-saving heat preserving hard bubbles the continuous popularization and application of application technology, the also more and more higher of the requirement to its fire resistance, particularly
Gb8624～2012 " Classification on burning behaviour for building materials " and the promulgation of gb50016～2014 " Code for fire protection design of buildings "
After enforcement, polyurethane foam is conveniently faced with acid test in fire retardant performance.Therefore, how to improve the resistance to of amino resins
High temperature has become this area technical barrier urgently to be resolved hurrily with fire resistance.
Content of the invention
In order to solve the problems referred to above of prior art presence, the invention provides a kind of inorganic hybridization propylene glycol etherificate trimerization
Melamine resin and preparation method thereof, with hexakis(hydroxymethyl)melamine as raw material, under the conditions of acid medium, reacts life with propylene glycol
Become tetramethyl etherified melamine polyimide resin or five methyl-etherified melmacs, then reacted with inorganic hybridization compound, generate
Inorganic hybridization propylene glycol is etherified melmac, has higher fire resistance and resistance to elevated temperatures.
The technical solution adopted in the present invention is as follows:
Inorganic hybridization propylene glycol etherificate melmac it is characterised in that: molecular structure is as follows:
X in described molecular structure is inorganic hybridization element, including one of b or sb.
Described inorganic hybridization propylene glycol be etherified melmac preparation method it is characterised in that: mainly include with
Lower step:
Under the conditions of acid medium, hexakis(hydroxymethyl)melamine and propylene glycol are carried out etherification reaction and obtains propylene glycol etherificate
Melmac, under agitation plus alkali carries out alkali neutralization reaction；
The melmac of etherificate and inorganic hybridization compound are reacted 0.5～2 under conditions of 100～110 DEG C little
When, hydridization reaction completes, and is cooled to 60～80 DEG C, filters out salt with filter, obtains inorganic hybridization propylene glycol etherified melamine
Polyimide resin.
Described inorganic hybridization propylene glycol be etherified melmac preparation method it is characterised in that: mainly include with
Lower concrete steps:
(1) etherification reaction
Add the propylene glycol that the r in hexakis(hydroxymethyl)melamine and claim 1 represents in reactor, acid adding adjusts ph
For 2.5～5.5, under conditions of 35～65 DEG C, mixing speed is 60～80 revs/min, and insulation 30～120min is etherified
Reaction, obtains propylene glycol etherificate melmac；
(2) alkali neutralization
Be stirred under the conditions of 40～80 revs/min of rotating speed, plus alkali to adjust ph be 8.0～9.0, this alkali N-process is protected
Hold temperature and be less than 50 DEG C；
(3) hydridization reaction
Add inorganic hybridization compound and water in reactor, be warmed up to 100～110 DEG C and react 0.5～2 hour, hydridization
Reaction completes；
(4) propylene glycol of distillation removing residual
Under conditions of vacuum 0.090～0.1mpa, 100～130 DEG C of temperature, steam the remaining adding in step (1)
Propylene glycol；
(5) cold filtration
It is cooled to 60～80 DEG C, add 2%～2.5% super-cell, filter out salt with filter, obtain inorganic miscellaneous
Change propylene glycol etherificate melmac.
Described inorganic hybridization propylene glycol be etherified melmac preparation method it is characterised in that: described step (3)
In inorganic hybridization compound be: sodium borate, potassium borate, boric acid, Firebrake ZB, boron phosphate, four water eight sodium borate, three oxidation two
