Description

Inorganic composite phase-change energy storage foamed insulation board and preparation method thereof
Technical field
The invention belongs to heat-insulating board for building wall material technical field, is a kind of inorganic composite phase-change energy storage foamed insulation board and preparation method thereof.
Background technology
Along with Chinese economic development, the energy shortage problem becomes increasingly conspicuous, and it is serious that heating buildings expends waste, and building energy conservation has become an important topic.Existing in the market foam heat-insulating board is to be the foam heat-insulating board that base material is made with organic polymer materials such as plastics, rubber.Such as: extruded sheet, polypropylene foam plate, styrofoam and polyurethane sheet etc., the base material source of this foam heat-insulating board is petrochemicals, not only will expend a large amount of energy, cause the raw material resources shortage, comprehensively do accounts is power consumption rather than energy-conservation, and complex manufacturing technology, cost height, and exist unsurmountable natural flaw: non-refractory, easy firing, anti-aging poor, discharge hazardous and noxious substances etc.Simultaneously, it is little that these heat preservation plate materials also exist heat storage coefficient, can not realize the function of absorption, storage and the release of heat energy.
Summary of the invention
The purpose of this invention is to provide a kind of good energy storage characteristic that has, can improve envrionment temperature, fire protection flame retarding effectively, light weight, ultimate compression strength height, good energy-conserving effect, nontoxic, inorganic composite phase-change energy storage foamed insulation board of environmental protection and preparation method thereof.
Realize that the technical scheme that purpose of the present invention is taked is: this heat preservation plate material is to be made by following raw materials in weight portion, 10～15 parts in phase-changing and temperature-regulating aggregate, 70～75 parts of cement, 2～3 parts of silicon-dioxide, 3～5 parts in flyash, 1～2 part of mineral fibre, 0.1～0.2 part of polypropene staple, 0.5～1 part of cement blowing agent, 0.1～0.2 part of stablizer.
Described mineral fibre adopts wherein any one fiber of sepiolite, aluminum silicate fiber, basalt fibre, glass wool.
The making method of the inorganic foamed heat preservation plate material of phase-change accumulation energy of the present invention is undertaken by following step:
(1) get flyash and silicon-dioxide respectively and pulverized 300～400 mesh sieves, it is standby to make powder;
(2) get phase-changing and temperature-regulating aggregate, cement, flyash powder, silicon dioxide powder, mineral fibre and polypropene staple by described proportioning, insert and add water mixing stirring 3～5 minutes in the stirrer, amount of water is by weight ratio: water: raw material total amount=10: 2.5～3.5, make mixed slurry;
(3) take by weighing cement blowing agent by described proportioning and add water, under the normal temperature state, make foams through foaming machine pre-frothing, wherein amount of water is by weight ratio: whipping agent: water=1: 25, then foams in inserting the foam stirrer, mixed slurry are stirred, churning time is 5 minutes, inject mould curing molding at normal temperatures, the curing conservation time is 14 days, can make inorganic composite phase-change energy storage foamed insulation board.
Adopted the phase-changing and temperature-regulating aggregate of state-of-the-art technology in the component raw material of inorganic composite phase-change energy storage foamed insulation board of the present invention, this aggregate not only has light weight, the intensity height, advantage such as accumulation of heat, good flame retardation effect, particularly solid-state and liquid phase transformation takes place in the transformation temperature scope external enwergy of setting in contained phase change material in it.When envrionment temperature raises, this phase change material will be changed to liquid state by solid-state, and follow absorption to store a large amount of heat energy; Otherwise when envrionment temperature reduced, this phase change material will be by liquid state to solid state transformation, and discharged latent heat to environment, and nature carries out two-ways regulation to the temperature of indoor environment thus, plays good energy-saving heat preserving effect.The cement that adopts makes the sheet material after solidifying form pumiceous texture under cement blowing agent and function of stabilizer, can alleviate the weight of body of wall, can strengthen heat preservation and insulation greatly again, and cement itself has the stronger hydraulicity and glued characteristic simultaneously.The flyash that adopts can be saved a large amount of cement and fine aggregate, reduces water consumption, improves the workability of concrete mix.The silicon-dioxide that adopts is also made powder, has active preferably and bigger specific surface area, can merge well with other raw material, makes the sheet material of making have high-strength characteristic.The mineral fibre and the polypropene staple that adopt mainly are tension, the ultimate compression strength that can increase sheet material greatly, prevent the broken and fracture of sheet material effectively, prolong the work-ing life of sheet material.This sheet material is by the synergy of each component raw material and reaction thereof, bring out the best in each other, fully keep and optimized good characteristic separately, and the used inorganic mineral synthesis material that is, therefore make the energy-saving and environmental protection, fire protection flame retarding of sheet material, waterproof and dampproof, resistance to compression, tension, anti-aging, and work-ing life etc., comprehensive technical performance reached comparatively ideal effect.
According to the inorganic composite phase-change energy storage foamed insulation board that such scheme is made, applicable to the insulation of skin body, its beneficial effect is:
(1) the phase change material temperature adjustment aggregate that adds in the feed composition of this sheet material, has the latent heat height, the phase transition process good reversibility, the expansion shrinkability is little, mistake is cold or superheating phenomenon is few, the transformation temperature scope is at 18～26 ℃, adapt with people's living environment optimal temperature, thereby make the phase-transition heat-preserving layer of making have good thermal storage effect, can improve indoor temperature environment effectively, energy-saving effect is remarkable.
(2) equivalent heat conductivity of this sheet material is less than the thermal conductivity of styrofoam, to compare bearing capacity big with styrofoam, and combine closely with structural sheet, be difficult for taking place crack performance, and intensity is good, from heavy and light, good environmental protection, its energy-saving effect is 1.3 times of styrofoam, can effectively avoid in use cracking, obscission, prevents that effectively security incident from taking place.
(3) this sheet material is green structural material, and is nontoxic, harmless, pollution-free, and raw materials cost drops into low, with low cost, production process is simple, can be made into serial sheet materials such as light heat insulation partition plate, thermal insulation external wall panel, heat preservation and soundproof thermal baffle, the market requirement is extensive, wide application.
