Abstract
The invention discloses a kind of low warpage flame-retardant reinforced PBT rly. PP Pipe Compound and purposes.It consists of following weight ratio composition: PBT resin 40 ~ 55%, fire retardant 10 ~ 15%, fire retarding synergist 2 ~ 7%, toughener 20 ~ 35%, that resist warping resin 2 ~ 9%, that resist warping filler 1 ~ 5%, toughner 2 ~ 5%, coupling agent 0.1 ~ 0.5%, oxidation inhibitor 0.2 ~ 0.8%, processing aid 0.2 ~ 0.8%.Every limit warpage performance and the four limit warpage performances of product of the present invention improve greatly, other mechanical properties, and as tensile strength, flexural strength, notched Izod impact strength, heat-drawn wire and flame retardant resistance etc., can remain on normal level and not decline.Various rly. is can be used for, as in the multiple rly. of letter electrical relay, power relay, guiding rly. etc. after shaping assembling.
Description
Technical field
The present invention relates to field of polymer technology compositions field, particularly relate to a kind of low warpage flame-retardant reinforced PBT rly. PP Pipe Compound.
Background technology
PBT is the saturated linear polyester of a kind of important hemicrystalline in thermoplastic polyester series, the regularity of its flexible fatty alcohol and rigidity phenyl ring combine make PBT have the high and resistance to fatigue of excellent mechanical performances intensity and chemical proofing, while low wear-resistant, the electric insulating quality of weather resistance good, frictional coefficient and arc resistance good, be easy to the advantages such as machine-shaping.But PBT also has, and notch sensitivity is large, heat-drawn wire is low, do not possess anti-flaming function and easily burn, the shortcoming such as molding shrinkage is large.Need in PBT application for this reason targetedly to its carry out physically modified with the requirement meeting market, especially electric industry possesses material requirements physical strength and flame-retarding characteristic, specifically to meet thin-wall part such as all kinds of relay product and also require the requirement of the low warpage of lower shrinkage.
Summary of the invention
A kind of existing superior mechanical physicals is the object of the present invention is to provide to have again superior dimensional to stablize low warpage flame-retardant reinforced PBT rly. PP Pipe Compound.
For achieving the above object, the invention provides a kind of low warpage flame-retardant reinforced PBT rly. PP Pipe Compound, it is characterized in that, the weight percent that composition presses following ingredients is formed, and includes:
