Abstract

The invention discloses an anti-radiation food package material based on titanium nitride and a preparation method thereof. The anti-radiation food package material comprises polymethacrylonitrile, aflexibilizer, an anti-oxidant, titanium nitride, arsenic trioxide, expanded vermiculite and rare earth oxide; wherein, by referring 100 weight parts of polymethacrylonitrile, the content of the flexibilizer is 3-8 weight parts, the content of the anti-oxidant is 0.3-0.8 weight parts, the content of the titanium nitride is 2-6 weight parts, the content of arsenic trioxide is 1-2.2 weight parts, thecontent of the expanded vermiculite is 10-15 weight parts, and the content of the rare earth oxide is 0.05-0.15 weight parts. The anti-radiation food package material has excellent mechanical properties and anti-radiation performance.

Description

technical field [0001] The invention relates to pipe fittings, in particular to a radiation-proof food packaging material based on titanium nitride and a preparation method thereof. Background technique [0002] The cable insulation material is an important part of the cable. It not only plays the role of insulation, but also plays the role of heat insulation and anti-corrosion. Once the insulation layer of the outer layer of the metal core is damaged, the cable will be greatly reduced. performance. At present, cable insulation materials are difficult to meet the actual needs in terms of radiation protection. Contents of the invention [0003] The object of the present invention is to provide a radiation-proof food packaging material based on titanium nitride and a preparation method thereof, through which the radiation-proof food packaging material based on titanium nitride has excellent mechanical properties and radiation-proof properties. [0004] In order to achieve ...
