preparation example Construction

[0027] A kind of preparation method of paraffin / graphene composite phase change material in warm baby of the present invention comprises the following steps:

[0028] S1. Take a phase-change material with a mass of A g, and heat and melt it at 100-120° C.;

[0029] S2. Weighing graphene with a mass of B g, adding it into the melted paraffin while stirring, fully stirring for 10-15min, and obtaining a composite phase change material after the graphene is uniformly dispersed.

[0030] The preparation method is simple, requires few instruments, is easy to operate, and is suitable for industrial production.

[0031] The matrix of the composite phase-change material prepared by the present invention is paraffin, and the mass ratio (A:B) of paraffin and graphene is 1:(0.01~0.03), and the range of the melting point of the composite phase-change material obtained is 56~85° C. Heating in microwave environment for 20-35s can realize rapid heat storage.

[0032] It should be noted that...

Embodiment 1

[0041] This embodiment provides a baby warmer, including: a tie, a pocket and an inner liner, the inner liner is arranged in the pocket, the tie is arranged at one end of the pocket, and a composite phase change material is arranged inside the inner liner. Among them, the preparation process of the composite phase change material is as follows:

[0042] (1) take the paraffin wax that quality is 30g and carry out pulverization treatment, heating makes it melt under 100 ℃;

[0043] (2) Take single-layer graphene 0.3g, add it in the paraffin wax that melts while stirring;

[0044](3) Stir fully on the stirrer for 10 minutes, so that the graphene is uniformly dispersed in the paraffin, and a composite phase change material is obtained.

Embodiment 2

[0046] This embodiment provides a baby warmer, including: a tie, a pocket and an inner liner, the inner liner is arranged in the pocket, the tie is arranged at one end of the pocket, and a composite phase change material is arranged inside the inner liner. Among them, the preparation process of the composite phase change material is as follows:

[0047] (1) take the paraffin wax that quality is 30g and carry out pulverizing treatment, heating makes it melt under 110 ℃;

[0048] (2) Take by weighing 0.6g of thermally exfoliated graphene, add it into the paraffin wax that melts while stirring;

[0049] (3) Stir fully on the stirrer for 12 minutes, so that the graphene is uniformly dispersed in the paraffin, and a composite phase change material is obtained.

Abstract

The invention discloses a warm bag. The warm bag comprises an inner container, and the interior of the inner container is provided with a paraffin / graphene composite phase-change material; and heat preservation energy storage is realized by microwave heating. According to the warm bag provided by the invention, the composite phase-change material arranged in the inner container is subjected to heat storage by microwaves, the composite phase-change material is heated uniformly, the heating time is short and only a few minutes or even tens of seconds, so that the warm bag is convenient for a user to use, can be reused for a plurality of times, and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of baby warmers, and in particular relates to a safe, convenient and reusable warm baby. Background technique [0002] Warm baby is a common product in daily life, which effectively solves people's needs for warmth in cold seasons. At present, some warm babies on the market use chemical reactions to obtain heat. This kind of warm babies are disposable products, which have the problems of polluting the environment and wasting resources; some warm babies are equipped with circuits inside, and their structures are relatively complicated. Uniform, sometimes there will be excessive expansion, there are certain safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe, convenient and reusable baby warmer for the deficiencies in the above-mentioned prior art. The heat storage of composite phase-change materials by microwaves can make the h...
