Description
Technical field
The invention belongs to technical field of coatings, more particularly to a kind of high temperature resistant radiation shielding coating and preparation method thereof.
Background technology
Radiation proof material has become a big problem of current material subject, with various high radiation devices appearance and extensively
Using the research of radiation proof material has caused the common concern of people.What the Japanese violent earthquake on March 11st, 2011 was triggered
Fukushima nuclear power station crisis has also triggered worry of the people to nuclear radiation；And various radiation sources exist in people's life, also compel to make one
Attention to radiation proof material；Radiation has been classified as the fourth-largest environment after water source, air, noise by the World Health Organization
Pollution sources, become the stealth " killer " for endangering human health, and protection radiation has become a top priority.
At present, radiation shielding coating is mostly using the addition heavy metal in coating composition or rare metal powder and its oxygen
Compound especially containing metallic compounds such as Ba, Pb, U, Lu or using composite deposite, but necessarily also brings constructional difficulties, attached
Put forth effort not enough, while the defects of function is inadequate, thus radiation shielding coating is also only applied in some special industries and special dimension, and
Using less in the fields such as people’s lives.
Therefore exploitation has both the radiation shielding coating of other additional properties as the task of top priority；With other additional properties
Radiation shielding coating can meet the basic function and its application field of coating, also comply with that coating is multi-functional, multi-field development
Requirement.
