Embodiment 1

[0012] Example 1, a flame retardant reinforced PBT material, including the following components by weight: 50%-55% of PBT, 31%-35% of filler glass fiber, 12%-18% of flame retardant, toughening agent 1 %-2.5%, silane coupling agent 0.8%-1.2%, antioxidant 0.1%-0.5%, lubricant 0.1-0.3%.

[0013] PBT is 51%, filler glass fiber is 32%, flame retardant is 15%, toughening agent is 1.8%, silane coupling agent is 1%, antioxidant is 0.1%, lubricant is 0.2%.

Embodiment 2

[0014] Embodiment 2, a kind of preparation method of flame retardant reinforced PBT material, its steps are, firstly material is dried, after drying, carry out high-speed mixing and extruding granulation by mixer, then injection molding pattern, finally carry out performance test; The temperature is controlled between 220-300°C, and the drying time is 1-2h; the temperature of the injection mold is controlled at 70-85°C.

[0015] The mixer is a three-dimensional swing mixer, and the inner wall of the barrel of the mixer is made of aluminum alloy after precision polishing, and the flame retardant is a brominated flame retardant, which is brominated triazine and / or brominated polystyrene.

[0016] Compared with the prior art, the flame-retardant reinforced PBT material of the present invention and its preparation method have the beneficial effects of fast crystallization speed and rapid prototyping; excellent mechanical properties, and pure PBT resin has excellent impact toughn...

Abstract

The invention provides a flame-retardant reinforced PBT material and a preparation method thereof. The material comprises the following components by weight: PBT 50%-55, filler glass fiber 31%-35%, flame retardant 12%-18%, toughener 1%-2.5%, silane coupling agent 0.8%-1.2%, antioxidant 0.1%-0.5%, and lubricant 0.1-0.3%. Compared with the prior art, the flame-retardant reinforced PBT material and the preparation method thereof according to the invention have the advantages that the crystallization speed is faster, molding is rapid, the mechanical properties are excellent, and after reinforced by glass fiber, pure PBT resin having excellent impact toughness but sensitive to a notch not only is improved in notch sensitivity and multiplied in flexural modulus, but also is improved in shrinkagerate.

Description

technical field [0001] The invention relates to the technical field of modification of polymer engineering plastics, in particular to a flame-retardant reinforced PBT material and a preparation method thereof. Background technique [0002] PBT resin is cost-effective, has excellent comprehensive mechanical properties, high temperature resistance, and is easy to flame retardant. It especially solves the shortcomings of nylon’s unstable water absorption size on the one hand and poor electrical performance of nylon water absorption on the other hand. After modification and processing, it includes the current low temperature resistance. 40℃ super-tough PBT is widely used in heat-resistant parts of home appliances and electronic appliances, and has the potential to replace nylon. However, in some specific occasions, the toughness of flame-retardant reinforced PBT materials is poor, so it is necessary to develop a PBT material that can solve the above problems.
