The application belongs to the technical field of carbon capture, and discloses an organic amine absorbent suitable for carbon capture of cement kiln flue gas, and a preparation method and application thereof. The organic amine absorbent comprises the following components in mass fraction: 3.0-6.0 parts of a main agent, 1.0 parts of an auxiliary agent, 0.1-0.5 parts of a promoter, and 0.1-0.5 parts of a stabilizer. The main agent comprises a binary amine, the auxiliary agent comprises a tertiary amine, and the promoter is one or more of 1,3,5-tri-tert-butylbenzene, tert-butyl acetate, triphenyl carbinol and triphenyl phosphine. The application can take into account high-temperature degradation resistance and selective adsorption of impurities, and simultaneously solves the problems of insufficient high-temperature stability and lack of anti-impurity interference ability of the organic amine absorbent in the prior art.

The application relates to the technical field of thermal insulation materials, and discloses a flame-retardant modified thermal insulation foam material and a preparation process thereof. The flame-retardant modified thermal insulation foam material is prepared from low-density polyethylene as a main material and 3,5-di-tert-butyl-4-hydroxyphenyl acetic acid grafting material and the like as auxiliary materials. Silicon phosphorus boron in the hydroxyl-terminated polydimethylsiloxane grafting material serves as a flame-retardant element, a dense thermal insulation oxygen isolation silicon phosphorus boron composite carbon layer is constructed at high temperature, and the flame-retardant effect is achieved. After 3,5-di-tert-butyl-4-hydroxyphenyl acetic acid is grafted to carboxyl-terminated polybutadiene, the antioxidant unit is fixed on the flexible long chain of the carboxyl-terminated polybutadiene through chemical bonding, the antioxidant activity of the antioxidant unit is retained, and the agglomeration phenomenon is inhibited, so that the flame-retardant modified thermal insulation foam material prepared by the application has the flame-retardant, antioxidant and thermal insulation performances.
