Description
Technical field
The present invention relates to a kind of high GWIT high CTI thin-walleds flame-proof glass fibres to enhance low warpage PET composite material and its preparation side
Method belongs to PET composite material field.
Background technology
PET material is polyethylene terephthalate, is linear thermoplastic's polymer, is that nineteen fifty-three is public by Du Pont earliest
Department realizes industrial production, is a kind of crystalline high polymer with higher melting temperature and high glass transition temperature.It can be
Good physical property is kept within the scope of wider temperature, its fatigue durability, rub resistance, resistance to ag(e)ing, resistance to insulating properties is dashed forward
Go out, while solvent resistant and acid resistance are stablized, thus be widely used.Product can be applied to outside capacitor made of modification
Shell, low-voltage electrical apparatus shell, connector and transformer framework etc..As PET products are in the extensive use of electronic enterprises, ring
It protects concept and has met primary demand, people also put forward higher requirements the electric property of product, in addition with product design
Diversity, more and more thinner product are come out one after another, and to product, fire-retardant thickness is also put forward higher requirements.
The PET composite material of Traditional Environmental-protection flame-proof glass fibre enhancing can only meet the flame retardant property more than or equal to 1.6mm thickness,
Glowing filament combustibility temperature (GWIT) generally can only achieve 700 DEG C or so, and creepage trace index can only achieve 200-225V or so.
Material is applied in electronic apparatus, can there is very big electrical property security risk.Also occurs high GWIT high CTI glass currently on the market
Fibre enhancing Flame-retardant PET product, but the crystallization rate of PET product itselfs is slower, needs higher forming temperature and molding cycle, it is raw
The product of output will appear warping phenomenon, it is made to be very restricted in engineering plastics application field.
Invention content
It is stuck up in order to which the GWIT and CTI that solve flame-proof glass fibre REINFORCED PET in the prior art cannot take into account simultaneously with product
The defects of Qu Xianxiang, the present invention, which provides a kind of high GWIT high CTI thin-walleds flame-proof glass fibre, enhances low warpage PET composite material and its system
Preparation Method.
In order to solve the above technical problems, the technical solution adopted in the present invention is as follows：
A kind of high GWIT high CTI thin-walleds flame-proof glass fibre enhances low warpage PET material, and raw material components include：
The PET viscosity be in high viscosity resin, inherent viscosity be 0.83-0.92 deciliter/grams；Glowing filament reinforcing agent is
The mixture of melamine and phosphate；CTI reinforcing agents are composite phosphate；Glass fibre is fine for alkali-free length, and filament diameter is
12μm；Aforementioned number is mass fraction.
GWIT is the warm-natured degree of glow wire ignition, and CTI is creepage trace index.
The application makes composition produce the collaboration of highly significant by the selection to glowing filament reinforcing agent, CTI reinforcing agents
Effect on the basis of not affecting the mechanical properties, can meet the requirement of fire-retardant, high GWIT and high CTI；Nucleating agent and mineral-filled
It is used according to proportioning collocation, reduces the molding cycle of product, meet the low warpage requirement of product；In addition glowing filament reinforcing agent is nitrogen
Phosphorus structural promoter is used in compounding the GWIT performances that can not only improve product with bromide fire retardant, while improves the fire-retardant of product
Performance.
The application further ensures the mechanical performance and flame retardant property of product to the specific choice of PET inherent viscosities.
In order to enhance the compatibility of mixture, while the impact property of product is improved, compatilizer is ethene-vinyl acetate

In order to further take into account GWIT and CTI simultaneously, it is preferable that fire retarding synergist is zinc stearate, antimony oxide and carbon
Sour zinc mass ratio is (2 ± 1)：1:1 mixture.In halogen flame retardant product, the presence of antimony oxide can seriously reduce CTI
Index, the present application replaces antimony oxide using zinc stearate and zinc carbonate department, in the premise for not influencing flame retardant effect
Under, while reduce the influence to CTI indexes.It by adding glowing filament and CTI reinforcing agents, compounds, and then is promoted with halogen system
The GWIT and CTI of product.
In order to while product flame retardant property is ensured, improve the GWIT and CTI of product, it is preferable that it is ten to have halogen fire retardant
At least one of bromine diphenylethane or brominated Polystyrene.
In order to further enhance the synergistic effect between each component, glowing filament reinforcing agent is nitrogen phosphate mixture RHPP-085-
3A-3h。
In order to further enhance the synergistic effect between each component, phosphate PK- of the CTI reinforcing agents for occasion east chemistry
5001。
In order to further enhance the synergistic effect between each component, product G WIT and CTI is made to be further improved, it is excellent
Choosing, antioxidant are any one in phenolic antioxidant or phosphite antioxidant.Further preferably, antioxidant is antioxidant
1010 and irgasfos 168 mass ratio be 1:The mixture of 1d.
In order to further ensure product low warpage properties energy, nucleating agent is the polyester nucleator P250 of Brueggemann.
Further preferably, it is mineral-filled be 1500 mesh talcum grain.
Above-mentioned high GWIT high CTI thin-walleds flame-proof glass fibre enhances the preparation method of low warpage PET material, using one-step method in height
Raw material is uniformly mixed in fast mixing machine, by double screw extruder extruding pelletization, drying, obtained pellet, pellet is again through note
Molding machine injection to get.
The unmentioned technology of the present invention is with reference to the prior art.
The high GWIT high CTI flame-proof glass fibres of the present invention enhance low warpage PET composite material, do not influence material mechanical performance,
Meet it is fire-retardant under the premise of, significantly improve the glowing filament combustibility temperature (GWIT) of material and creepage trace index (CTI),
By adding nucleating agent and mineral-filled, the warpage issues of product are solved, the molding cycle for reducing product while, which also reduces, matches
Fang Chengben.
