Embodiment 1

[0013] In the stirred tank that is connected with circulating cooling water, add successively the guar gum hydroxypropyl trimethyl ammonium chloride that weight fraction is 1% and the superfine pyrophyllite powder that weight fraction is 2%, stir 10min under 500rpm; Add weight The fraction is 0.1% of the dispersant, stirred at 1500rpm for 2 hours; the weight fraction of 5% polymer water-absorbing resin (sodium polymethacrylate, guar gum and high-substituted hydroxypropyl cellulose in the mass percentage is 2:1 : 1), stirring at 1500rpm for 2 hours, with water as the balance; after standing for 3 hours, bagging and sealing to obtain a new type of polymer cooling agent that has plasticity, can maintain a certain shape for a long time, and is not easy to flow out and pollute the packaging.

Embodiment 2

[0015] In the stirred tank that has circulating cooling water, add successively the guar gum hydroxypropyl trimethyl ammonium chloride that weight fraction is 5% and the superfine pyrophyllite powder that weight fraction is 1%, stir 15min under 800rpm; Add weight The fraction is 1% dispersant, stirred at 1800rpm for 3h; add the polymer water-absorbing resin with a weight fraction of 1% (the mass percentage in polysodium methacrylate, guar gum and high-substituted hydroxypropyl cellulose is 3:1 : 1), stirred at 1800rpm for 2 hours, with water as the balance; after standing for 3 hours, bagged and sealed to obtain a new type of polymer cooling agent that has plasticity, can maintain a certain shape for a long time, and is not easy to flow out and pollute the packaging.

Embodiment 3

[0017] In the stirred tank that is connected with circulating cooling water, add successively the guar gum hydroxypropyl trimethyl ammonium chloride that weight fraction is 8% and the superfine pyrophyllite powder that weight fraction is 3%, stir 20min under 1000rpm; Add weight The fraction is 5% of the dispersant, stirred at 2500rpm for 3 hours; the weight fraction of 1% polymer water-absorbing resin (sodium polymethacrylate, guar gum and high-substituted hydroxypropyl cellulose in the mass percentage is 4:1 : 1), stirred at 2500rpm for 4 hours, with water as the balance; after standing for 10 hours, bagged and sealed to obtain a new type of polymer cooling agent that has plasticity, can maintain a certain shape for a long time, and is not easy to flow out and pollute the packaging.

Abstract

The invention relates to a preparation method of a shape plastic macromolecule coolant. Guar gum hydroxyl propyltrimethyl ammonium chloride of which the weight fraction is 1%-10% and superfine pyrophyllite powder of which the weight fraction is 1%-5% are added sequentially into an agitating vessel where a circulating cooling water is introduced, and are agitated at 500-1000rpm for 10-20 minutes, a dispersing agent of which the weight fraction is 0.1%-5% is added and agitated at 1500-2500rmp for 2-4 hours, a super absorbent polymer of which the weight fraction is 1%-15% is added and agitated at 1500-2500rmp for 2-4 hours, the water is the balance, and the mixture stands for 3-10 hours and is bagged and sealed to obtain the novel plastic macromolecule coolant which can keep certain shape for a long period of time and does not flow out easily to contaminate a packing product. The preparation method is simple in process and does not need heating operation, used equipment is processing production equipment in common use, and the preparation method can achieve industrial application.

Description

technical field [0001] The invention belongs to the technical field of cold storage, relates to a polymer cool storage agent, in particular to a preparation method of a polymer cool storage agent which has plasticity in shape and can maintain a corresponding shape for a long time. Background technique [0002] Phase change cold storage materials are functional materials for storing cold energy in phase change cold storage systems. According to the composition of cold storage agents, they can be divided into inorganic materials, organic materials and polymer materials. Inorganic phase change cold storage materials are corrosive, and have the disadvantages of supercooling and phase separation during the phase change process; organic materials are usually paraffin, fatty acids, polyols, higher alkanes, etc., which have low thermal conductivity, low density, and storage capacity per unit volume. It has the disadvantages of small energy capacity, high price, and some organic comp...
