Embodiment 1

[0037] A PBT / PET alloy material, comprising the following preparation steps:

[0038] S1. Dry PBT and PET at 130°C for 5h for use, and dry ultra-high molecular weight polyethylene and polyamide resin at 90°C for 40min for use;

[0039] S2, mix the dried 3kg PBT, 5kg PET, 0.4kg ultra-high molecular weight polyethylene, 0.8kg polyamide resin, 0.03kg nucleating agent and 0.1kg acrylate at a stirring speed of 300r / min for 40min to make the mixture , and then the mixture was extruded at 285 ° C to obtain PBT / PET alloy material;

[0040] The average molecular weight of the ultra-high molecular weight polyethylene used is 7 million; the polyamide resin used is a copolymer polyamide resin with a brand name of CM4000; the nucleating agent used is talcum powder; the acrylate used is ethyl acrylate.

Embodiment 2-9

[0042] Examples 2-9 are all based on Example 1, and the only difference from Example 1 is that the consumption of each raw material is different, as shown in Table 2 for details.

Abstract

The invention relates to the field of alloy materials, and particularly discloses a PBT / PET alloy material and a preparation method thereof. The PBT / PET alloy material is prepared from the following raw materials in parts by weight: 25 to 40 parts of PBT, 30 to 60 parts of PET, 3 to 6 parts of ultra-high molecular weight polyethylene, 3 to 15 parts of polyamide resin, 0.2 to 0.35 part of nucleating agent and 0.3 to 3 parts of acrylate. The preparation method comprises the following steps: S1, dehumidifying and drying the PBT, the PET, the ultra-high molecular weight polyethylene and the polyamide resin respectively; and S2, mixing the dried PBT, PET, ultra-high molecular weight polyethylene, polyamide resin, a nucleating agent and acrylate to prepare a mixture, and then extruding the mixture to prepare the PBT / PET alloy material. The PBT / PET alloy material disclosed by the invention is relatively high in thermal deformation temperature and deformation temperature stability.

Description

technical field [0001] The present application relates to the field of alloy materials, and more particularly, to a PBT / PET alloy material and a preparation method thereof. Background technique [0002] PBT is the abbreviation of polybutylene terephthalate, and PET is the abbreviation of polyethylene terephthalate. Both are thermoplastic resins developed in the 20th century. It has the advantages of elasticity and excellent electrical insulation, and has good mechanical properties in a wide temperature range. Due to the low glass transition temperature of PBT, it is easy to cause uneven heating and cooling, causing deformation; PET has a slow crystallization speed and a long molding cycle, these shortcomings limit the application of the two. [0003] PBT / PET alloy materials are prepared by blending PBT and PET to synthesize the respective properties of PBT and PET and make up for the defects in the performance of a single component. PBT / PET alloy material has the respectiv...
