preparation example 1

[0068] 2 parts by weight of a crosslinking agent (N,N'-methylenebisacrylamide), 20 parts by weight of sodium bentonite and 500 parts by weight of water were added to the container, and stirred to be fully dissolved. After the complete dissolution, acrylic acid (70 parts by weight) and acrylamide (30 parts by weight) were added to make them fully dissolved, and sodium hydroxide solution (20 wt %) was added dropwise for neutralization, so that the neutralization degree of acrylic acid reached 70%. Then, 0.1 parts by weight of ammonium persulfate and 0.1 part by weight of sodium bisulfite were added, stirring was continued for 5 minutes, and a static polymerization reaction was performed at 60° C. for 3 hours to obtain a gel. The obtained gel was cut into pieces and sent to a desiccator at 200° C. for drying, pulverized, and sieved to obtain a superabsorbent resin with a particle size of 80-200 μm, and its water absorption ratio was 1029.1 g / g.

[0070] 1 part by weight of a crosslinking agent (N,N'-methylenebisacrylamide), 20 parts by weight of sodium bentonite and 500 parts by weight of water were added to the container, and stirred to be fully dissolved. After the complete dissolution, acrylic acid (80 parts by weight) and acrylamide (20 parts by weight) were added to make them fully dissolved, and sodium hydroxide solution (20 wt %) was added dropwise for neutralization, so that the neutralization degree of acrylic acid reached 80%. Then, 0.1 parts by weight of ammonium persulfate and 0.1 part by weight of sodium bisulfite were added, stirring was continued for 5 minutes, and a static polymerization reaction was performed at 60° C. for 3 hours to obtain a gel. The obtained gel was cut into pieces and sent to a desiccator at 200° C. for drying, pulverized, and sieved to obtain a superabsorbent resin with a particle size of 80-200 μm, and its water absorption ratio was 882.5 g / g.

preparation example 3

[0072]2 parts by weight of a crosslinking agent (N,N'-methylenebisacrylamide), 30 parts by weight of sodium bentonite and 500 parts by weight of water were added to the container, and stirred to fully dissolve. After the complete dissolution, acrylic acid (80 parts by weight) and acrylamide (20 parts by weight) were added to make them fully dissolved, and sodium hydroxide solution (20 wt %) was added dropwise for neutralization, so that the neutralization degree of acrylic acid reached 80%. Then, 0.1 weight part of initiator ammonium persulfate and 0.1 weight part of sodium hydrogen sulfite were added, and the mixture was stirred for 5 minutes, and the static polymerization reaction was carried out at 60° C. for 3 hours to obtain a gel. The obtained gel was cut into pieces and sent to a desiccator at 200° C. for drying, pulverized, and sieved to obtain a superabsorbent resin with a particle size of 80-200 μm, and its water absorption ratio was 969.1 g / g.

Abstract

The invention relates to the field of high temperature resistance and heat insulation, and discloses a cooling and heat insulating material composition, a cooling and heat insulating material and applications thereof. The cooling and heat insulation material composition contains a superabsorbent resin, an adhesion promoter, a thixotropy control material and a thermal insulation filler, and the superabsorbent resin is used as 100 parts by weight, and the content of the adhesion promoter is 0.1- 3 parts by weight, the content of the thixotropy regulating material is 1-15 parts by weight, and the content of the thermal insulation filler is 5-30 parts by weight. The heat insulation material provided by the invention has good viscosity, high water absorption performance, heat insulation performance and thixotropic performance, can solidify rapidly, and has good adhesion to the tank wall at the same time, and plays a good protective effect.

Description

technical field [0001] The invention relates to the field of high temperature resistance and heat insulation, in particular to a cooling and heat insulating material composition, a cooling heat insulating material and applications thereof. Background technique [0002] In recent years, with the development of the petrochemical industry, the number of storage tanks in the tank farm has increased and the scale has become larger and larger, and fire accidents have occurred frequently in the tank farm. When a fire occurs in a storage tank, the hydrocarbon fire will release strong thermal radiation, and the adjacent storage tanks are subjected to strong thermal radiation. The following situations may occur: 1. The strength of the adjacent storage tanks decreases, the tank wall is torn, and the tank 2. The medium in the tank volatilizes, the pressure in the tank increases, and a physical explosion occurs; 3. The medium in the tank volatilizes, the pressure in the tank increases, a...
