example 1

[0022] Weigh pork suet and place it in a tissue pulverizer for 20 minutes. Mix the pulverized material and water at a mass ratio of 5:1 and put it in an iron pan. Heat to 100°C, keep it warm and cook for 1 hour. After boiling, take advantage of Filter with hot mesh to separate the filtrate; mix the filtrate and carbon nanofibers at a mass ratio of 10:1 and pour it into a stainless steel tray, and move the stainless steel tray into a closed greenhouse with a temperature of 35°C and a relative humidity of 60%. In the middle, let stand rancidity treatment for 5 days to obtain the rancid product for use; add methyl methacrylate to the separatory funnel, wash with 5% sodium hydroxide solution until the washing liquid is colorless, and then deionize Washed with water to neutrality, dried with anhydrous sodium sulfate for 5 days, then distilled under atmospheric pressure, and collected the fraction at 98°C to obtain refined methyl methacrylate; the above-mentioned refined methyl methac...

[0024] Weigh pork suet and place it in a tissue pulverizer for 25 minutes, mix the pulverized material and water at a mass ratio of 5:1 and put it in an iron pan, heat it to 102°C, keep it warm and cook for 1.5 hours. After boiling, Filter the filtrate with a mesh screen while it is hot, and separate the filtrate; mix the filtrate and carbon nanofibers at a mass ratio of 10:1 and pour it into a stainless steel tray, and move the stainless steel tray into a sealed container with a temperature of 40℃ and a relative humidity of 65%. In the greenhouse, let it stand for 6 days to obtain the rancid product, which is ready for use; add methyl methacrylate to the separatory funnel, wash with 5% sodium hydroxide solution until the washing liquid is colorless, and then use it Ionized water was washed to neutrality, dried with anhydrous sodium sulfate for 6 days, and then distilled at atmospheric pressure. The fraction at 99°C was collected to obtain refined methyl methacrylate; the above-...

Abstract

The invention relates to a preparation method of a rancidity shaped heat storage material, and belongs to the technical field of heat storage material preparation. In the heat storage material prepared by the invention, biomass oil and nano-carbon fibers are firstly mixed and in rancidity, the biomass oil is in the rancidity and hydrolyzed by microorganisms under high-temperature and high-humiditysealing conditions to generate a large amount of fatty acids and free ester groups, and monomeric methacrylate is polymerized to form a rigid hard colorless transparent material, thereby being capable of ensuring that a matrix does not deform or melt when the fatty acids are melted, playing a role of protecting the matrix, and further achieving a shaping effect. On the other hand, the free estergroups generated by the rancidity are introduced to the surfaces of the nano-carbon fibers under the action of the microorganisms, and high thermal-conductivity nano-carbon fibers are introduced to the composite shaped heat storage material, so that the thermal conductivity of the composite shaped heat storage material can be enhanced. The rancidity shaped heat storage material prepared with the method is not easy to leak, high in thermal conductivity and broad in application prospects.

Description

Technical field [0001] The invention relates to a preparation method of a rancid substance shaped heat storage material, and belongs to the technical field of heat storage material preparation. Background technique [0002] Heat storage material is a new type of chemical material that can store heat energy. It undergoes a phase change at a specific temperature, and is accompanied by heat absorption or release, which can be used to control the temperature of the surrounding environment or to store heat energy. It stores heat or cold and releases it when needed, thereby improving energy efficiency. [0003] The working process of heat storage materials includes two stages: one is the heat storage stage, that is, excess power, industrial waste heat, waste heat, or solar energy during the peak period is stored through the heat storage material; the second is the heat release stage, that is, during use The heat is released through the heat storage material and used for heating and hea...
