Abstract

The invention relates to the technical field of engineering plastics and discloses an anti-nuclear radiation composite material and a preparation method thereof. The anti-nuclear radiation composite material is prepared from following components in parts by weight: 25-80 parts of polyphenyl ether, 5-50 parts of impact-resistant polystyrene, 5-65 parts of modified lead powder, 5-55 parts of modified lead fiber, 5-40 parts of composite filler, 0.1-1.5 parts of a coupling agent, 0.3-1 part of an antioxidant and 0.5-2.5 parts of a lubricant. The anti-nuclear radiation composite material is easilyformed, not only has excellent anti-nuclear radiation performance, but also keeps excellent mechanical properties, plasticity, elasticity and stability, is long in service life and high in cost performance and can be widely applied to the field of nuclear radiation.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a method for preparing a nuclear radiation-proof composite material. Background technique [0002] Anti-nuclear radiation materials refer to materials used to prevent or weaken the radiation damage caused by nuclear radioactive radiation sources, and can be divided into anti-penetrating radiation materials and surface radiation protection materials. Heavy metal materials such as lead, cadmium, and steel have good protective properties, but due to poor plasticity and high processing difficulty, they are difficult to be used in the preparation of radiation protection products, especially in the field of flexible nuclear radiation protection products. Surface nuclear radiation protection materials are generally formed by coating or compounding a layer of anti-radiation layer on the surface of the product through processing methods. This processing method is complex, and...
