Abstract
The purpose of the present invention is to provide a kind of fiber glass reinforced PBT/PET materials, it is characterized in that, it (similarly hereinafter) counts by weight percentage, including following component: 29%~65% PBT, 1%~15% PET, 1%~15% nylon66 fiber, 20%~30% glass, 10%~15% toughening compatilizer and 1%~3% auxiliary agent.The present invention uses alloying process, and nylon is blended in PBT, PET and forms stable heterogeneous structure, not only can reduce warpage, but also will not reduce the mechanical property of material；The impact property for improving PBT simultaneously, accelerates the crystallization rate of PET；In addition, the present invention is also added into toughening compatilizer so that PBT and it is polyamide blended when, it may occur that amide-ester exchange reaction, impact strength are higher by 50% or so than single epoxy systems impact；And using a variety of light stabilizers compounding in the form of improve weather-proof effect.
Description
Technical field
The invention belongs to modified PBT/PET technical fields, are related to a kind of PBT/PET alloy material of fiberglass reinforced.
Background technique
Reinforced polyester is the important species of modified poly ester, its main feature is that high-intensitive, high rigidity and excellent wearability,
As a kind of important structural material.
Fiber glass reinforced PBT/PET is widely applied as heat resistance, mechanical property, the excellent material of processability, but its
The appearance of product, lustrous surface and weatherability are not fully up to expectations, need to further improve.
For above problem, can be solved by 4 directions:
(1) highly viscous PBT, the short fibre that special size system is drawn the selection of basic raw material: are selected
(T436HK), no bisphenol-A, wet-heat resisting.
(2) it uses alloying process: blending other polymer in PBT, PET and form stable heterogeneous structure, can reduce
Warpage.
(3) add nylon: the impact property of PBT can be improved in nylon, while can accelerate the crystallization rate of PET.
(4) light stabilizer: a variety of compoundings improve weather-proof effect.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of high intensity, high durable, high-dimensional stability
PBT/PET alloy material and preparation method thereof.
The purpose of the present invention is be achieved through the following technical solutions:
The purpose of the present invention is to provide a kind of fiber glass reinforced PBT/PET materials, which is characterized in that by weight percentage
(similarly hereinafter) it counts, including following component:
