Description
Technical field
The present invention relates to heat accumulation plastics and preparation method thereof technical field more particularly to phase-change thermal storage plastics, preparation method
And its application.
Background technique
With the miniaturization and lightweight of electronic product, it is desirable to which it greatly improves integrated level, and integrated level is higher, and heat dissipation is asked
Topic is also more serious.Gather to form hot spot so having heat in order to prevent, it is necessary to rapidly by the transfer of the heat of hot spot or
It stores, after product miniaturization, inner space is more narrow, generallys use the plastics that Heat Conduction Material shifts heat
Shell, and current plastic shell does not have heat storage function, reaches heat saturation soon, cannot achieve the lasting transfer of heat
And storage；
It is constituted for example, the lithium battery group of large capacity is combined the lithium battery monomer to link together by numerous warps in series and parallel, lithium
Battery pack can generate a large amount of thermal energy during charging and discharging, how these thermal energy are transmitted to plastic shell as soon as possible, made
Lithium battery reduces rapidly temperature；
Equally, capacitor, which works long hours, is easy to produce largely, and capacitor is more, generates heat more severe, how these thermal energy is use up
Fast is transmitted to urgent need to resolve point problem in plastic shell and industry.
In addition, mobile phone can all generate greatly during the charging process and in prolonged use in mobile communication apparatus field
How these thermal energy are transmitted to urgent need to resolve point problem in plastic shell and industry by the heat of amount as soon as possible.
In addition, flexible LED field, also needs to develop the new material for capableing of a large amount of heat accumulations, for this purpose, occurring in the market
Phase transformation plastics, phase transformation refer to the process of substance from a kind of phase transition be another phase, along with the absorption of energy when undergoing phase transition
And release, the storage of heat is realized by the phase transformation of plastics, however, in phase transformation plastics, if phase-change material addition is very few, just
The heat accumulation effect that can not have been played；If phase-change material addition is excessive, brittleness increases, and when injection molding is easily broken, and fraction defective is high.
In addition, the bracket of electronic product also has higher requirement to heat dissipation and heat accumulation, current plastics are also difficult to meet need
It asks.
To solve the above-mentioned problems, phase-change material is added in the plastic in the prior art, however, phase-change material is at high temperature
The phenomenon of leakage can occur, on the one hand phase-change material separate out from matrix will lead to the subsequent difficulty that molding is mixed
It improves, on the other hand, after phase-change material separate out, the performance sharp fall of phase-change thermal storage plastics can be made, influence its storage
Hot property.
Therefore, it is badly in need of providing a kind of phase-change thermal storage plastics, preparation method and application, so as to solve the deficiencies in the prior art.
Summary of the invention
An object of the present invention is to provide a kind of phase-change thermal storage plastics, so as to solve the deficiencies in the prior art.
Another object of the present invention is to provide the preparation methods of above-mentioned phase-change thermal storage plastics.
Another object of the present invention is to provide the application of above-mentioned phase-change thermal storage plastics.
To achieve the above object, the present invention adopts the following technical scheme that:
Phase-change thermal storage plastics, each component including following parts by weight:
20~50 parts of plastics and modified 10~70 parts of phase transformation powder, the modified phase transformation raw powder's production technology are as follows: will
The heating fusing of phase transformation powder, then adds modifying agent in the phase transformation powder of fusing, and additive amount weight ratio is the 2% of phase transformation powder
~40%, powder is kept the temperature in water-bath or oil bath after mixing, then uses shaker vibration, then uses oil-Absorbing Sheets oil suction, then use ball
Grinding machine or sand mill grind powder, obtain the modification phase transformation powder.
Preferably, the modifying agent is any in expanded graphite, nanometer titanium dioxide silicon powder and hollow microsphere powder
One or several kinds of combinations
Preferably, the plastics appointing in PP plastics, ABS plastic, PS plastic, PU plastics, PA plastics, PPS plastics
The combination for one or several kinds of anticipating.
Preferably, any one of the phase transformation powder in paraffins, paraffin, fatty acid, PE wax and polyethylene glycol
Or several combination
It preferably, further include 5-40 parts of fire retardant.
Preferably, the fire retardant is selected from phosphorus flame retardant, nitrogenated flame retardant, bromide fire retardant, antimony oxide and hydrogen
Any one in aluminium oxide or several combinations.
Preferably, the alkane carbon atom number of the paraffins is between 10-60.
The preparation method of above-mentioned phase-change thermal storage plastics weighs each component according to formula, and then phase-change material is added and moulds
In material, injection molding obtains the phase-change thermal storage plastics.
The application of above-mentioned phase-change thermal storage plastics, the phase-change thermal storage plastics can be used for battery, support of electronic product
And housing region.
Compared with prior art, phase-change thermal storage plastics of the invention have the advantages that phase-change thermal storage of the invention
Plastics, containing suitable phase transformation powder, for phase transformation enthalpy spectrum in 20-200 J/g, specific heat capacity has been more than 2.3J/gK, meets electricity
The demand of pond and capacitor to heat absorption and thermal storage performance, phase transformation powder has the function of heat-absorbing energy-accumulating, since phase transformation enthalpy is big, heating
Slowly, plastics can absorb more heats, and the heat that the heat generating spot in battery and capacitor generates is quickly transferred to phase transformation storage
In thermoplastic materials, so that heat generating spot cooling is faster, the technical problem of battery and the fever of capacitor field can be well solved；Phase transformation powder
Body passes through modifier modification, and modifying agent is bigger serface, the powder containing micropore, after mixed, increases specific surface
Product, powder contain a large amount of micropore, and phase transformation powder enters in micropore to be lockked securely, make it under the high temperature conditions, Bu Huicong
Separate out in micropore solves the problems, such as that phase-change thermal storage rubber is fuel-displaced, not only improves only operating for moulding process below
Property, it is often more important that, it can guarantee significantly it under the high temperature conditions, keep the stabilization of thermal storage performance for a long time, with similar product
Phase transformation, the stability and duration of heat accumulation are 4-5 times of similar product in the market, even if using for a long time, under thermal storage performance
Drop is no more than 2-3%.
Specific embodiment
