Abstract

The invention discloses a radiation pollution-proof wall mortar. 8-10 parts, 20-50 mesh barite sand 65-75 parts, 100-200 mesh barite powder 10-20 parts, 250-400 mesh barite powder 8-15 parts, modified composite fiber 6-10 parts , 8-12 parts of nano-lead powder, 5-8 parts of starch ether, 6-10 parts of cellulose thickener, and modified composite fibers include modified polypropylene fibers, graphene oxide modified carbon fibers and modified glass fibers. The present invention controls the segregation and delamination caused by barite inside the mortar by grading the particles of barite and adding other admixtures in the mortar, and solves the problem that the radiation-proof mortar is prone to delamination, segregation and flow. The mortar has good mechanical strength and toughness, no delamination, no segregation, no sagging, and good workability.

Description

technical field [0001] The invention belongs to the technical field of radiation protection of special mortar, and mainly relates to a mortar for preventing radiation pollution for walls. Background technique [0002] With the rapid development of modern science and technology, medical equipment is changing with each passing day, and various high-energy rays are more and more widely used in the medical field, which not only brings convenience to people, but also brings some benefits to human beings. Radiation Hazard. Today, radiation hazard has been recognized as the fourth largest public hazard after air pollution, water pollution and noise pollution. According to relevant researches, electromagnetic radiation is an inducing factor that causes miscarriage, infertility, teratogenicity and other diseases in pregnant women; excessive electromagnetic radiation directly affects children's tissue development, bone development, decreased vision, decreased hematopoietic function o...
