Glue for nuclear-radiation shielding lead garment and production method thereof

Abstract

The invention discloses glue for a nuclear-radiation shielding lead garment, relating to a nuclear-radiation protection technology. The production method comprises the following steps: mixing natural glue, an accelerator, an oxidant, stearic acid, an antiager, rosin, light calcium carbonate, sulphur with gasoline; and then heating at high temperature so that the mixture is fully dissolved. The process is simple and reasonable and is easy for production and manufacture, and the prepared glue is in liquid state, is easy to spray and is easy to volatilize in the high temperature sulfidation process of gasoline. The glue for the nuclear-radiation shielding lead garment easily forms glue slurry, can perform sulfidation with lead fiber at low temperature, has good physical-mechanical properties, is in favor of economical production and lead fiber fixing and is good for repeated dressing and using; and on the premise of not reducing radiation protection function, the material of the lead garment is saved, and the lead garment is convenient for dressing and has good durability, so that the radiating time of maintenance personnel on the site is reduced by 50%.

Description

technical field [0001] The invention relates to nuclear radiation protection technology, in particular to the technical field of material production for making lead clothing liners for radiation protection. Background technique [0002] Studies have shown that the external radiation of nuclear power plants is mainly γ-rays, which mainly come from the fission products of nuclear reactions and the pipelines and valves activated by neutrons. Due to the appearance of activated corrosion products in the pipelines, radioactive particles in the pipelines are deposited, making the control area The environmental dose in many maintenance work places is relatively high, which increases the external exposure dose of the staff, which is generally relieved by shielding. Therefore, in the selection of shielding materials, strive to be efficient, safe, cheap and space-saving, usually steel, lead, ordinary concrete and heavy concrete are selected. The strength of steel is better, but the pr...

AI Technical Summary

Problems solved by technology

Practice has proved that although lead plate and lead skin products have better anti-nuclear radiation effects, they are used in large quantities when building a shielding system, which is difficult to build, low in work efficiency, produces a lot of waste, and has high potential risks; and lead plate products have poor conformability. Can not be bent, not suitable for shielding special-shaped equipment such as pipes, valves, etc., and it is easy to drop and hurt people or damage equipment if it is accidentally operated

The products, coatings and adhesives made of lead powder mixed with rubber and polyethylene foam materials have certain flexibility, but because the lead powder particles are easy to accumulate, it is difficult to mix evenly in the base material, so the shielding performance is not uniform. And the lead equivalent is low, rubber and polyethylene are easy to age, which affects the shielding effect and brings the danger of radiation to the staff

Hollow microspheres made of heavy metals such as lead are lightweight and high-strength materials. Although they have excellent anti-nuclear radiation performance, they are expensive and costly. They are generally used in nuclear rocket engines to prevent nuclear radiation leakage
