Problems solved by technology

[0003] 1. Lead is used as shielding. Because lead is soft, supports must be used as supports, and the joints need to be repeatedly sealed. The construction is difficult, and lead is poisonous. It is not suitable for strong radiation, and it is harmful to human health, and the cost is high;
[0004] 2. Barium cement for protection: easy to crack, large thickness, large occupation area, and poor effect;
[0005] 3. Application No. 88105952 discloses a protective coating, which is thick and heavy, and the equivalent per pb / m 2 About 30kg in weight, easy to crack and fall off

Abstract

A multipurpose radiation proof material with wide spectrum in environmental protective type is prepared in weight share from 20-60 share of multi-composition radiation proof material, 15-30 share of inorganic cementing material, 0-60 share of packing material and 0-50 share of intensifying material. The prepared material can be used to make various wall bodies and composite slab material.

Description

technical field [0001] The invention belongs to a radiation-proof material, which is mainly used for protecting the radiation produced by X, R, neutrons and radioactive substances. Background technique [0002] At present, the protection against harmful radiation produced by x, r, neutron and other radioactive substances at home and abroad mostly adopts the following methods: [0003] 1. Lead is used as shielding. Because lead is soft, supports must be used as supports, and the joints need to be repeatedly sealed. The construction is difficult, and lead is poisonous. It is not suitable for strong radiation, and it is harmful to human health, and the cost is high; [0004] 2. Barium cement for protection: easy to crack, large thickness, large occupation area, and poor effect; [0005] 3. Application No. 88105952 discloses a protective coating, which is thick and heavy, and the equivalent per pb / m 2 It weighs about 30kg and is easy to crack and fa...
