Title:
PREPARATION METHOD FOR LOW-TEMPERATURE GLUE FOR LOW-TEMPERATURE PUMP ACTIVATED CARBON ADSORPTION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/121491
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of low-temperature pumps, and specifically relates to a preparation method for a low-temperature glue for a low-temperature pump activated carbon adsorption material. The preparation method disclosed in the present invention comprises the blending modification of polytrifluorochloroethylene and sulfonated graphene. The low-temperature glue has excellent mechanical properties and good cold flow resistance, wear resistance, dimension stability and processability, has good adhesion to a metal bottom plate and a particularly outstanding low-temperature resistance, has no embrittlement and creep in a cooling medium such as liquid nitrogen, can be briefly used at the temperature close to zero degrees under certain conditions, is beneficial to prolonging the service life of a low-temperature pump panel and a low-temperature pump, has the lowest water vapor permeability in all plastics, has no gas permeation and does not combust, is a good barrier polymer and does not affect low-temperature gas adsorption.
