Description

Polymer electric heating heat carrier and preparation method thereof

Technical field

The invention belongs to the electric space heating appliance technical field, specifically, relate to polymer electric heating heat carrier of using on a kind of electric space heating appliance and preparation method thereof.

Background technology

At present, 3,000 ten thousand of area, domestic Ningbo City, Zhejiang Province year production filling type electric space heating appliances, 2,200 ten thousand of year outlets, its electric heating heat carrier of selecting for use is to lead oil generation heating (lead i.e. two benzol mixtures of oil generation, it is the mixture of 26.5% biphenyl and 73.5% phenyl ether).Lead oil generation and have boiling point height (258 ℃) (370 ℃ can be used 750-1100 days); Flammable but do not have explosion hazard; Its toxicity is very slight; Its main drawback is very easily to permeate the freestone cotton packing, and metallic gasket need be used in all pipe flange junctions during use.

The type of heating that electricity oil well electric space heating appliance adopts is the mineral oil heating.No. 45 machine oil of high temperature commonly used and No. 60 machine oil of high temperature in the production, its Heating temperature can reach 250 ℃.The saturated vapo(u)r pressure ratio water of mineral oil low, its saturated vapo(u)r source is easier to, homogeneous heating, need not pressurize; Shortcoming is that oil viscosity is big, and with increasing duration of service, the transmission of heat by convection film coefficient reduces gradually, and there is potential safety hazard in poor heat stability, easily decomposes when being higher than 250 ℃, inflammable.

In sum: the electric heating heat carrier that present domestic enterprise selects for use, inflammable, toxic, power consumption can be big, the 60 minutes temperature of starting shooting can reach about 96 ℃).Existing domestic market oil-filling type electric heating warmer lowest power calculates by 0.55 yuan of civilian electricity price/degree more than 2000 watts, 2 degree electricity/hour * calculate=13.2 yuan/day * 30 days/month=396 yuan, the demand charge height 12 hours 0.55 yuan/degree * every days.

How to solve the problems of the technologies described above, then be the problem that the present invention faced.

Summary of the invention

The invention provides a kind of polymer electric heating heat carrier and preparation method thereof, inflammable, toxic, the problem that consuming electric power is big that can solve that prior art exists.

The present invention is by providing a kind of brand-new polymer electric heating heat carrier, good environmental protection, and consuming electric power is low.

For solving the problems of the technologies described above, the present invention adopts following technical proposals to be achieved, and a kind of polymer electric heating heat carrier comprises the component of following weight percentage: deionized water 20～30%; Edible glycerol 5～10%; Edible ethanol 10～20%; Edible baking powder 4～5%; Edible knob sweet 2～5%; Edible D-sodium iso-vc 3～5%; Thickening material 20～30%; Edible oil 10～25%.The edible sweet formal name used at school of knob is N-(3.3 dimethylbutyl).

In technique scheme of the present invention, also have following technical characterictic: described thickening material adopts at least a in edible sweet ester of molecular distillation or the edible Gelatinum oxhide.Edible Gelatinum oxhide adopts thickness 12 degree of national Specification.

In technique scheme of the present invention, also have following technical characterictic: the concentration of described edible ethanol is 45～50%, and this concentration is weight percentage.

In technique scheme of the present invention, also have following technical characterictic: comprise that also accounting for gross weight is 1～2% pigment, described pigment is for edible light green.

In technique scheme of the present invention, also have following technical characterictic: described edible oil is at least a in peanut oil or the soya-bean oil.

A kind of preparation method of polymer electric heating heat carrier adopts the component of above-mentioned weight percentage, and step is as follows:

1) deionized water in the stainless cylinder of steel is warmed to 65～80 ℃;

2) add edible baking powder;

3) the edible knob of adding is sweet;

4) add edible D-sodium iso-vc;

5) add the edible sweet ester of molecular distillation, stirring and dissolving boiled 4～6 minutes, cooled off standby fully;

Adding concentration is 45～55% edible ethanol when 6) using, edible glycerol, and edible oil, stirring and dissolving promptly obtains described polymer electric heating heat carrier.

The sweet temperature that improves thermophore of all strengthening of deionized water wherein, edible glycerol, edible ethanol, edible baking powder and edible knob, the gasification temperature of deionized water is 100 ℃, the gasification temperature of edible glycerol is 220 ℃, and the gasification temperature of edible ethanol is 30～80 ℃; Edible D-sodium iso-vc uses as oxidation inhibitor; Edible sweet ester of molecular distillation and edible Gelatinum oxhide use as thickening material.The polymer electric heating heat carrier for preparing is sealed in the heating unit of warmer and uses.Lead oil generation as the electrically heated carrier because traditional electric oil well warmer adopts, the boiling point of oil is more than 250 ℃, and can not gasify, and when temperature reaches 250 ℃, can expand and produce oil smoke, dependence expansion heat supply; And polymer electric heating heat carrier of the present invention can gasify, and relies on the steam heat supply of gasification, can obtain the heat of same specification product under lower powered condition, therefore can save energy greatly.

Compared with prior art, the present invention has the following advantages and positively effect:

The electric space heating appliance that adopts polymer electric heating heat carrier of the present invention with adopt mineral oil or lead oil generation same specification product and compare:

1, verification experimental verification, save electric energy about 50%: 15 minutes temperature of 1000 watts of starts of the highest electric energy of polymer electric heating heat carrier can reach more than 98 ℃.1 degree electricity/hour * calculating=6.6 yuan/day * 30 days/month=198 yuan 12 hours 0.55 yuan/degree * every days, same sex product is compared, and adopts the heating of polymer heating agent to can save energy 50%.

2, environmental protection: the polymer thermophore all adopts foodstuff additive to mix, and is no inflammable, no explosive, nontoxic, meets national environmental standard.

3, the production cost expense is low: adopt the special-purpose thermophore ratio of polymer to lead oil generation and compare with mineral oil same sex price and can reduce cost 30%, every of domestic existing filling type electric space heating appliance adds about 18 yuan of the costs of oil, and 12.6 yuan of every production costs of the special-purpose thermophore of polymer.

4, temperature height: started shooting 15 minutes, the temperature of whole warmer can reach more than 98 ℃.
