Embodiment 1

[0023] This embodiment relates to a preparation process of radiation-proof flexible rubber, comprising the following steps:

[0024] S1, weigh 5g barium sulfate, 20g carbon black, 5g zinc oxide, 1g stearic acid, 2.5g sulfur, 1.5g accelerator DM, 1.5g accelerator EZ, 0.5g antioxidant RD, 1.5g antioxidant, 0.1g Carboxymethyl cellulose, 0.1g polyvinylpyrrolidone and 65g water were mixed and treated with a sand mill for 30min to prepare filler slurry for subsequent use;

[0025] S2, adding the filler slurry prepared in step S1 to 166g of natural rubber latex, stirring and dispersing for 1 hour, to obtain prevulcanized latex;

[0026] S3, spread a layer of pre-vulcanized latex in the mold, and then place a layer of 1mm thick lead-coated carbon nanotube paper (Suzhou First Element), and then pour the pre-vulcanized latex. After the pre-vulcanized latex solidifies, it is dehydrated and dried. Then put it into a vulcanization mold for vulcanization to obtain radiation-proof flexible ...

Abstract

The invention discloses anti-radiation flexible rubber and a preparation process thereof, and belongs to the technical field of high polymer material manufacturing. The preparation process of the anti-radiation flexible rubber comprises the following steps: S1, weighing a certain amount of filler, zinc oxide, stearic acid, sulfur, an accelerant, an anti-aging agent, a wetting agent and a dispersing agent, adding water, and sanding to prepare uniformly mixed filler slurry; s2, adding the filler slurry into latex, and fully stirring to obtain pre-vulcanized latex; and S3, paving a layer of pre-vulcanized latex in a mold, then placing at least one layer of carbon nanotube material plated with shielding elements, paving a layer of pre-vulcanized latex between two adjacent layers of carbon nanotube materials plated with the shielding elements, finally paving a layer of pre-vulcanized latex, and carrying out solidification, dehydration, drying and vulcanization molding to obtain the anti-radiation flexible rubber. The prepared anti-radiation flexible rubber has the advantages of being good in shielding effect, good in lead equivalent uniformity, small in rubber density, good in abrasionresistance and the like, the application field is wide, the preparation method is simple, and industrial production can be conducted.

Description

technical field [0001] The invention relates to a technique in the field of polymer material manufacturing, in particular to a radiation-proof flexible rubber and a preparation process thereof. Background technique [0002] With the progress of society, we have more and more opportunities to be exposed to radiation, and the problem of radiation safety has become increasingly prominent and has attracted much attention. The vast number of scientific researchers have also done a lot of work in the research of radiation protection materials and equipment, and accumulated certain technologies and experiences, but they are far from meeting the safety requirements brought about by the development of nuclear technology today. [0003] The materials used for human radiation protection protective gear and radiation protection sealing materials are mainly lead clothing or lead rubber. Lead rubber is a rubber filled with a large amount of lead oxide or lead salt. Ordinary anti-radiatio...
