Abstract
The invention relates to a PET (polyethylene terephthalate)-modified polycarbonate alloy material, belonging to the technical field of high polymer materials. The PET-modified polycarbonate alloy material is prepared from the following raw materials in parts by weight: 50-60 parts of polycarbonate resin, 8-12 parts of PET resin, 5-10 parts of filler, 0.5-0.8 part of stabilizer and 1.2-1.6 parts of lubricant. The PET-modified polycarbonate alloy material has the characteristics of no cracking and excellent wear resistance. The invention has the following advantages: the bending strength is 65-74 MPa, the tensile strength is 55-60 MPa, and the elongation at break is 35-40%.
Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to a kind of polycarbonate alloy material of PET modification.
Background technology
Polycarbonate is a kind of material of excellent property, but exist processing temperature too high, and the goods unrelieved stress is high, easy cracking, and the shortcoming such as not wear-resisting.PET is ethylene glycol terephthalate, has an injection moulding good, the advantages such as high abrasion resistance, and by PET and polycarbonate, in conjunction with improving polycarbonate easily cracking and not wear-resisting shortcoming, technical scheme described below is based on producing under this prerequisite.
Summary of the invention
Task of the present invention is to provide a kind of and contributes to overcome the easy to crack and shortcoming that wears no resistance of polycarbonate and have the polycarbonate alloy material of the PET modification of processing characteristics preferably.
Task of the present invention completes like this, a kind of polycarbonate alloy material of PET modification, and its raw material by following parts by weight forms:
In a specific embodiment of the present invention, described polycarbonate resin is bisphenol A polycarbonate.
In another specific embodiment of the present invention, described PET resin is polyethylene terephthalate.
In another specific embodiment of the present invention, described filler is nano-calcium carbonate.
In another specific embodiment of the present invention, described stablizer is the two diphosphites of two (2,4-di-tert-butyl-phenyl) tetramethylolmethanes.
Also have a specific embodiment of the present invention, described lubricant is polyethylene wax.
Have and do not ftracture by the polycarbonate resin alloy material of a kind of PET modification provided by the invention, the characteristics of high abrasion resistance.Flexural strength 65 ~ 74MPa, tensile strength 55 ~ 60MPa, elongation at break 35 ~ 40%.
