New radiation-shielding composite material

Abstract

The invention relates to a new radiation-shielding composite material, which comprises, by weight part, 15-30 parts of polyvinyl chloride, 5-10 parts of rare earth oxide, 5-6 parts of polyethylene, 10-15 parts of tungsten oxide powder, 2-5 parts of a coupling agent, 10-20 parts of barium sulfate powder, 1-2 parts of water-based acrylic acid emulsion acid, 1-2 parts of sodium hydroxide, 0.5-1 part of a cosolvent, 2-4 parts of a water-based acrylic acid emulsion, 0.5-1 part of ethyl acetate, 5-10 parts of toluene, 2-3 parts of dipentaerythritol, 3-6 parts of tris(2-butoxyethyl) phosphate, 3-5 parts of styrene-butadiene latex, 2-4 parts of ethyl vinyl acetate, 0.2-0.4 part of triphenyl phosphate, and 20-40 parts of tungsten oxide. The new radiation-shielding composite material can be made into various shapes, can be attached to or coat a radiant object, and can reduce the effect and damage to the human body by the radiant object. The new radiation-shielding composite material is small in irritation and is green and free of pollution.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a new radiation-proof composite material. Background technique [0002] With the development of science and technology, traditional X-ray and γ-ray shielding materials generally use high-density materials such as concrete or cement. Later, a series of non-polar or organic polymer materials were gradually developed, but the existing polymer materials are more irritating. , there is an urgent need to provide a new anti-radiation composite material that is less irritating and environmentally friendly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a radiation-proof material aiming at the deficiencies of the prior art. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a new anti-radiation composite material, in parts by weight, comprising 15-30 ...
