Abstract

The invention discloses PC / PBT alloy over-CTI plastic and a preparation method thereof. The plastic is prepared from the following raw materials in parts by weight: 30 parts of PC resin, 20 parts of PBT resin, 3 parts of compatilizer, 16 to 20 parts of wollastonite and 20 to 30 parts of metal oxide. The preparation method of the PC / PBT alloy over-CTI plastic is characterized by comprising the following steps: weighing 30 parts by weight of PC resin, 20 parts by weight of PBT resin, 3 parts by weight of compatilizer, 16-20 parts by weight of wollastonite and 20-30 parts by weight of metal oxide, and mixing in a storage barrel to obtain a premix for later use; mixing in a mixer, and operating in an extruder. According to the PC / PBT alloy over-CTI plastic and the preparation method thereof, the operation is simple, the plastic preparation raw materials are conveniently and uniformly mixed, stable and uniform melt extrusion in a double-screw extruder is facilitated, meanwhile, the molten raw materials are conveniently and rapidly cooled, the cooling efficiency is improved, subsequent granulation is facilitated, the plastic manufacturing time is saved, and the plastic manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to a PC / PBT alloy per-CTI plastic and a preparation method thereof, belonging to the technical field of plastic preparation. Background technique [0002] Plastic is a polymer compound that is made of monomer as raw material and polymerized by addition or polycondensation reaction. Its resistance to deformation is moderate, between fiber and rubber. It is composed of additives such as additives and pigments; the main component of plastic is resin; resin refers to a polymer compound that has not been mixed with various additives; the term resin was originally named after the lipids secreted by animals and plants, such as rosin, Shellac, etc.; resins account for about 40% to 100% of the total weight of plastics; the basic properties of plastics are mainly determined by the nature of the resins, but additives also play an important role; some plastics are basically composed...
