Abstract
A kind of normal temperature for solid-state warm transmittance possibility of reversal material, relates to the reversible change material of a kind of temperature transmittance down.Comprise by 0.1～5.0% polystyrene, polyvinyl alcohol or Natvosol; 0.1～5.0% its chlorinated polypropylene, Natvosol or hydroxypropylcellulose; 0.1～5.0% KCl, NaCl or MgSO
4Liquid materials with temperature dependent reversible change of transmittance with 80.0～99.3% water are formed is characterized in: the xanthan gum, carrageenin, gelling gum of mixing the 0.03%-0.5% mass ratio in the reversible change material of above-mentioned liquid state make it become solid at normal temperatures as solidifying agent.Normal temperature of the present invention has kept the reversible change character of original transmittance for solid-state materials with temperature dependent reversible change of transmittance down, and stability is improved greatly, and its application mode no longer is confined in the interlayer, can directly use as the temperature control material.Material of the present invention can be used for the window of buildings, and shipping vehicle etc. play better intelligent thermoregulating effect, have saved energy consumption.
Description
Technical field
The present invention relates to the reversible change material of a kind of temperature transmittance, specifically is to be the solid-state construction window that can be used under the normal temperature, also can be used for the warm transmittance possibility of reversal material of aspect such as shipping vehicle.
Background technology
The cool in summer and warm in winter of house is human dream, but reality is cold in winter and hot in summer often, reason is that the sun can not change with seasonal variation to solar absorptance and the thermal emissivity that certain latitude ground input angle in the summer in winter bigger variation and material of construction takes place, can only come a home from home of constructing architecture with heating and refrigeration, this with regard to mass consumption earth fossil energy, polluted environment, aggravated Global Greenhouse Effect.According to statistics, the American Architecture energy consumption has accounted for 38% of the whole America total energy consumption, and China also reaches about 30%.Be save energy, people have adopted multiple mode that buildings is incubated insulation, utilize sun power but all fail all fully to dispose in two seasons of summer in winter, thus concerning requiring buildings cool in summer and warm in winter equal very big limitation of existence.
In view of the sun is a kind of permanent, clean harmless energy, makes full use of sun power and be undoubtedly a kind of effective way that solves architectural energy consumption.In this regard, people have adopted multiple material and device fully to dispose and have utilized sun power, and have obtained certain achievement in research.
In general, window is absolutely necessary to buildings, and it removes has effects such as architectural lighting, ventilation, also to building thermal environments generation effect.As everyone knows, general window glass has the characteristic through visible light, reflects infrared light, this characteristic can be used to make the active sun in the winter time and get hot room, thereby the energy consumption of heating buildings is reduced, but to summer, this characteristic then makes the buildings indoor overheating, thereby building refrigeration air-conditioner energy consumption is increased greatly.Hence one can see that, need work out and a kind ofly have high transmission rate, summer in the winter time and have temperature that low-transmittance and transmittance change the reversible change material of normal temperature temperature transmittance near the Building Heat comfort temperature, could satisfy the application requiring of winter, Xia Liangji simultaneously, the level of comfort of building thermal environments is improved significantly, for this reason, the present patent application person has developed above-mentioned materials, and has applied for patent of invention.But the sub-normal temperature of this material is down liquid state, so come with some shortcomings in the life-time service, different components layering, flocculation for example can occur, can only be as the packing material use in the interlayer etc.
Summary of the invention
The objective of the invention is to disclose a kind of solid-state materials with temperature dependent reversible change of transmittance that is at normal temperatures, this material is solid and keeps its original performance again substantially.Can improve the stability of liquid material greatly, and its application mode no longer is confined in the interlayer.
In order to achieve the above object, the contriver has found a kind of reversible change material of existing temperature transmittance that makes to become solid-state solidifying agent at normal temperatures, and the dosage that mixes, thereby overcome the labile factor that during use the layering of liquid materials with temperature dependent reversible change of transmittance, flocculation etc. influence quality, and must be when using with double glazing as all deficiencies such as carryings.Can directly be painted on construction window easily, shipping vehicle etc. make it play better intelligent thermoregulating effect.This temperature transmittance possibility of reversal material is to mix xanthan gum, carrageenin or gelling gum to form on the materials with temperature dependent reversible change of transmittance proportioning basis of liquid state, and volume is 0.03%-0.5%.Specifically form by following material:
Comprise liquid materials with temperature dependent reversible change of transmittance proportioning
Polystyrene, polyvinyl alcohol or Natvosol 0.1～5.0%
Its chlorinated polypropylene, Natvosol or hydroxypropylcellulose 0.1～5.0%
KCl, NaCl or MgSO4 0.5～10%
Water 80.0～99.3%
Be characterized in: mix xanthan gum, carrageenin, gelling gum in the materials with temperature dependent reversible change of transmittance of above-mentioned liquid state, volume is the 0.03%-0.5% mass ratio; And be the benchmark adjustment with the total amount after mixing, make total amount satisfy 100%.
Xanthan gum, carrageenin, gelling gum are the commercially available prod.Wherein the production firm of xanthan gum is a Shanghai upright strange auxiliary chemicals company limited; Model is a technical grade.The production firm of carrageenin is the intelligent marine organisms of Qingdao moral Science and Technology Ltd.s; Model is a food grade.The production firm of gelling gum is the pertinent Bioisystech Co., Ltd in Zhejiang; Model is a food grade.
Material of the present invention is transparent solid at low temperatures, changes opaque solid under the high temperature into, and transparent and opaque transformetion range is different and different with material mixture ratio, and promptly the temperature of transmittance reversible transition is determined by material mixture ratio.Adjust material mixture ratio, can satisfy of the different requirements of different uses field transmittance.
The great advantage that the present invention has is to become solid at normal temperatures, but has the reversible change character of original transmittance simultaneously; Next is the stability that can improve original material greatly; Be that its application mode no longer is confined in the interlayer at last.
