Embodiment 1-3

[0047] A kind of ultra-high fluidity, high temperature resistance, high tenacity PBT / PP composite material, its raw material formula is as shown in table 1, and its preparation method comprises the following steps:

[0048] Mix PP SZ30S and di-tert-butyl peroxide well, then feed it from the main feeding port of the extruder, melt, extrude, and granulate in the extruder to obtain melt-blown grade PP. The melt-blown grade PP is tested by the instrument, and the melt flow rate is above 1500g / 10min (230°C, 2.16kg); the melt-blown grade PP is mixed with the above-mentioned PBT material, acrylic acid, weak alkaline degradation agent, primary antioxidant, secondary antioxidant The agent is mixed evenly in the high mixer according to the above ratio, and then fed from the main feeding port of the extruder, melted, extruded, and granulated in the extruder to obtain ultra-high fluidity, high temperature resistance, and high toughness PBT / PP composite material

Abstract

The invention provides a PBT/PP composite material, and a preparation method and an application thereof. The composite material is prepared from the following raw materials by weight: 75.2-88.2 partsof PBT, 5-10 parts of melt-blown grade PP, 5-10 parts of acrylic acid, 2-4 parts of a weakly alkaline degradation agent, 0.4 part of a main antioxidant and 0.4 part of an accessory antioxidant, wherein the melt-blown grade PP is prepared by processing and granulating a PP material with a melt flow rate of about 30 g/10 min (230 DEG C, 2.16 kg) and di-tert-butyl peroxide by virtue of a double-screwextruder. The PBT/PP composite material disclosed by the invention has the characteristics of ultrahigh flowability, high temperature resistance and high toughness.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a PBT / PP composite material and a preparation method and application thereof. Background technique [0002] During the refining and processing of fuel oil, impurities such as particulate matter and moisture will inevitably be introduced, and moisture will also be mixed in due to the influence of the air environment during storage and transportation. Traditional metal filter screens and filter screens cannot filter nano-scale impurity particles and moisture. Although the melt-blown cloth made of PP by the melt-blown method has a strong filtering ability to filter nano-scale particles, PP itself is a hydrophobic material and cannot filter moisture. At the same time, fuel filtration requires a very high temperature, and PP has a low melting point and poor temperature resistance. PBT has strong water absorption and can be used as a natural oil-water separation material. ...
