Abstract
The invention discloses a kind of method of composite flame-retardant agent modified unsaturated polyester, mainly includes the following steps: that (1) ammonium polyphosphate is uniformly mixed under agitation with unsaturated polyester (UP), then obtain ammonium polyphosphate modifying after initiator solidifies;(2) unsaturated polyester (UP) is modified to get modified unsaturated poly- to a kind of composite flame-proof through montmorillonite, zinc borate, two formicester of methyl acid phosphate, ammonium polyphosphate modifying and initiator respectively.Compared with prior art, composite flame-retardant agent of the invention and unsaturated polyester (UP) have good compatibility, can greatly improve ammonium polyphosphate dispersibility in the base and interface interaction, have significant cooperative flame retardant effect.
Description
Technical field
The present invention relates to flame retarded polymeric material technical fields, and in particular to a kind of composite flame-retardant agent modified unsaturated polyester
Method.
Background technique
Unsaturated polyester resin is a kind of linear polymer with ester bond and unsaturated double-bond, usually by two
What first carboxylic acid and dihydric alcohol were synthesized by polycondensation reaction.Unsaturated polyester (UP) aggressiveness, which is generally dissolved in styrene, forms solution,
The thermosetting resin patent CN102838779A for being formed by curing three-dimensional-structure through initiator initiation when use discloses a kind of compound
Type expanding fire retardant modified heat convertible resin.The mixed solution of phosphorus oxychloride and dioxane is added to expansible graphite and two
Six ring of oxygen is uniformly mixed, and polyalcohol and catalyst is added, obtains a kind of phosphorous organic expander type fire retardant, but in the technique mistake
Fire retardant compatibility is bad in journey.Patent CN105384387A discloses a kind of composite flame-retardant agent and its preparation method and application,
But fire retardant additive amount is big in the technical process.Unsaturated polyester resin is that thermosetting plastics purposes is most widely a kind of,
Since with easy to process, raw material, the excellent performances such as cheap, waterproof and oilproof, resistant to chemical etching are widely used in communications and transportation for it
Industry (vehicle internal/external and other structures component, the various helmets, traffic sign etc.), urban duct facility (pipeline, cabinet,
Switch etc.), building construction (door and window, dining table seat, ornament materials, plate, fire-fighting equipment etc.), power industry (small members, electricity
Device switch, cover, motor blade etc.) and the fields such as medical, building materials, craftwork, dress ornament, sport, light industry device village (referring to document
Baljinder K.Kandola, John R.Ebdon, Piyanuch Luangtriratana, Latha
Krishnan.Polymer Degradation and Stability, 2016,127:56-64.).Therefore, it is related to unsaturated poly-
The product of ester resin plays irreplaceable role in various fields of recent life.
Ammonium polyphosphate is a kind of aggretion type inorganic phosphate esters fire retardant, and general formula is (NH4)n+2PnO3n+1, theoretical phosphorus,
Nitrogen content is respectively 31.92wt% and 14.44wt%, is widely used in the fire-retardant of the polymer materials such as plastics, fiber, rubber.
When the polymer material containing ammonium polyphosphate is subjected to fire, ammonium polyphosphate will resolve into polyphosphoric acid and ammonia first, then more phosphorus
Acid is reacted with hydroxyl or other synergist groups such as ethoxy cyanurate or ring urea formaldehyde resin, forms unstable phosphoric acid
Ester.
It in phosphate dehydration, will carbonize comprising formed in the surface of polymer material and resist heat source
Carbon foam.In addition, viscous molten layer or watch crystal can also be obtained on polymer surfaces in addition to forming carbon foam, protect
Polymer material is protected from heat and oxygen.In flame retardant thermoset resins such as unsaturated polyester (UP) and epoxy resin, ammonium polyphosphate can
To be used alone.However, ammonium polyphosphate has very strong hydrophily and a degree of layering, the layering in use process can drop
The anti-flammability of low material.In addition, the poor compatibility of ammonium polyphosphate and polymer, this will damage the mechanical performance of material.In order to gram
The shortcomings that taking above-mentioned ammonium polyphosphate, the present invention have carried out corresponding modification to ammonium polyphosphate.
Montmorillonite layer has very strong fixed function to unsaturated polyester (UP) molecule, and the barrier action of montmorillonite layer can
To prevent the transmission of heat and combustible volatile, promote polymer at charcoal, simultaneously because cannot fire completely after polymer matrix is heated
It burns and is converted into more charcoal residues.Anti-flammability mostlys come from montmorillonite layer to the barrier action and burning of interlayer macromolecular
The formed layer of charcoal in surface it is heat-insulated, every matter act on (referring to document Goodarzi V, Monemian S A, Angaji M T, et
Al.Journal of applied polymer science, 2008,110 (5): 2971-2979.).
The compactness of layer of charcoal can be enhanced in zinc borate, this will easily discharge water at relatively high temperatures and form boric acid, to promote
The formation of pyrolytic layer in unsaturated polyester (UP).Zinc borate is a kind of multifunctional fire retardant, have it is fire-retardant, at charcoal, suppression cigarette, suppression glow
With prevent from generating the multiple functions such as molten drop (referring to document Braun U, Schartel B, Fichera M A, et al.Polymer
Degradation and Stability, 2007,92 (8): 1528-1545.).It can be melted at a higher temperature in solid phase
Change, and form vitreum coating, isolation air effect is played on the surface of blocked polymer.
Methyl-phosphoric acid dimethyl ester, is a kind of low-viscosity liquid additive flame retardant being halogen-free, its phosphorus content is up to
25%, excellent flame retardancy is (referring to document Feng F, Qian L.Polymer Composites, 2014,35 (2): 301-
309.).In addition to excellent fireproof performance, relative to other fire retardants, there are also lower temperature resistance, plasticity, UV stable, drainings
Property, self-extinguishment the advantages that, the characteristics of especially it can be used for the coating article of transparent or light graceful color, this is other resistances
The characteristic that combustion agent does not have.
Summary of the invention
For the flame retardant property for improving unsaturated polyester (UP), the invention proposes a kind of composite flame-retardant agent modified unsaturated polyesters
Method, specifically includes the following steps:
(1) ammonium polyphosphate is uniformly mixed under agitation with unsaturated polyester (UP) in mass ratio 1: 1;
(2) initiator is added into step (1) resulting solution under agitation, obtains solution A;
(3) it is put into drying box after solution A being infused film, pulverizes and sieves after solidification demoulding, obtains ammonium polyphosphate modifying;
(4) montmorillonite is mixed under agitation with unsaturated polyester (UP), both control mass ratio is (1~9): 68, temperature
Degree is 20 DEG C~30 DEG C, and mixing time is 10min~20min, obtains solution B after mixing;
(5) zinc borate is mixed under agitation with step (4) resulting solution B, controls zinc borate dosage and step
(4) mass ratio of montmorillonite is 2 in: (1~9), temperature are 20 DEG C~30 DEG C, and mixing time is 10min~20min, and mixing is equal
