Abstract
A kind of expansion type flame retardant and preparation method thereof, expansion type flame retardant it be to be formulated by weight percentage by following effective component: melamine pyrophosphate, montmorillonite, phytic acid；The preparation method of the expansion type flame retardant is the following steps are included: be dissolved in dehydrated alcohol for melamine pyrophosphate first；It adds montmorillonite and phytic acid and is allowed to be sufficiently mixed；Dehydrated alcohol therein is evaporated with rotary evaporator again, obtains dry pulverulent solids fire retardant.When unsaturated polyester resin burning is added in the expansion type flame retardant, montmorillonite is combined with melamine polyphosphate, and many cells for generating an expansion burn carbon-coating, as the physical barriers for preventing heat transfer with cutting off fuel gas；In addition, montmorillonite and melamine polyphosphate act synergistically, generates P-N-P, P-N-C and C=C structure and the structure of carbon-coating is promoted to become more complete and intensive, to achieve the purpose that fire-retardant.
Description
Technical field
The present invention relates to a kind of expansion type flame retardants and preparation method thereof.
Background technique
Unsaturated polyester resin (UPR) is a kind of most important thermosetting resin, due to its excellent mechanical performance, processing
Advantage, good corrosion resistance, the weight ratio of low cost and high intensity, are widely used in many fields.However, insatiable hunger
It is poor with the flame retardant property of polyester resin UPR, it hinders it and widely utilizes.Therefore, fire retardant currently on the market exists
The problem of thermal stability and flame retardant property of unsaturated polyester resin cannot be promoted.
Summary of the invention
Its of the invention purpose, which is that, provides a kind of expansion type flame retardant and preparation method thereof, solves currently on the market
Fire retardant there are problems that the thermal stability of unsaturated polyester resin and flame retardant property cannot be promoted.
It adopts the technical scheme that achieve the above object, a kind of expansion type flame retardant, it is by following effective component
It is formulated by weight percentage: melamine pyrophosphate 90%-95%, montmorillonite 3%-6%, phytic acid 2%-4%.
A kind of preparation method of expansion type flame retardant, method includes the following steps:
(1) melamine pyrophosphate is dissolved in dehydrated alcohol first；
(2) montmorillonite and phytic acid are added and is allowed to be sufficiently mixed；
(3) dehydrated alcohol therein is evaporated with rotary evaporator again, obtains dry pulverulent solids fire retardant.
Beneficial effect
The present invention has the following advantages that compared with prior art.
It is an advantage of the invention that when unsaturated polyester resin burning is added in the expansion type flame retardant, montmorillonite and melamine
Amine Quadrafos combines, and many cells for generating an expansion burn carbon-coating, as prevention heat transfer and cutting fuel gas
Physical barriers；In addition, montmorillonite and melamine polyphosphate act synergistically, P-N-P, P-N-C and C=C structure are generated simultaneously
The structure of carbon-coating is promoted to become more complete and intensive, to achieve the purpose that fire-retardant.
Specific embodiment
A kind of expansion type flame retardant, it is formulated by weight percentage by following effective component: melamine coke phosphorus
Hydrochlorate 90%-95%, montmorillonite 3%-6%, phytic acid 2%-4%.
A kind of preparation method of expansion type flame retardant,
Method includes the following steps:
(1) melamine pyrophosphate is dissolved in dehydrated alcohol first；
(2) montmorillonite and phytic acid are added and is allowed to be sufficiently mixed；
(3) dehydrated alcohol therein is evaporated with rotary evaporator again, obtains dry pulverulent solids fire retardant.
Embodiment 1
(1) melamine pyrophosphate 92.5% is dissolved in dehydrated alcohol first；
(2) montmorillonite 5% and phytic acid 2.5% are added and is allowed to be sufficiently mixed；
(3) dehydrated alcohol therein is evaporated with rotary evaporator again, obtains dry pulverulent solids fire retardant.
Embodiment 2
(1) melamine pyrophosphate 90% is dissolved in dehydrated alcohol first；
(2) montmorillonite 6% and phytic acid 4% are added and is allowed to be sufficiently mixed；
(3) dehydrated alcohol therein is evaporated with rotary evaporator again, obtains dry pulverulent solids fire retardant.
Embodiment 3
(1) melamine pyrophosphate 95% is dissolved in dehydrated alcohol first；
(2) montmorillonite 3% and phytic acid 2% are added and is allowed to be sufficiently mixed；
(3) dehydrated alcohol therein is evaporated with rotary evaporator again, obtains dry pulverulent solids fire retardant.
Pulverulent solids fire retardant of the present invention when in use, first gathers pulverulent solids fire retardant with unsaturation
The mixing of ester resin；Mixture is stirred at room temperature 1 hour again.In whipping process, in the mixture by initiator B PO dissolution；
It pours the mixture into mold later, precuring in 2 hours is carried out on the basis of 80 DEG C, is cured as 3h after 110 DEG C
Afterwards, molding flame retardant unsaturated polyester resin is obtained.
Solidify using mixture of the mold to fire retardant and unsaturated polyester resin, required shape can be obtained
Flame retardant unsaturated polyester resin；Also molding flame retardant unsaturated polyester resin can be machined, obtains required shape；
Obtained flame retardant unsaturated polyester resin is not required to other processing, itself has fire-retardant effect.
