Precipitated calcium carbonate of the present invention is calcium carbonate content 〉=85% precipitated calcium carbonate.
Aluminosulfate cement of the present invention is that 42.5 grades of aluminosulfate cements also claim high-alumina cement.
The dry-mix additive series product that polypropylene fibre of the present invention selects for use Beijing Orient Fu Cheng company limited to produce for polypropylene fibre FC-05(), has cracking resistance/antiseepage/shock resistance/tension/improve workability.
Redispersion latex powder of the present invention, Vltra tears and 206 organosilicon moisture repellents also all are selected from the dry-mix additive series product that Beijing Orient Fu Cheng company limited produces.
The production method of phase-change thermal-storage material of the present invention, it is characterized in that: earlier with paraffin, synthetic fatty acid, the adipic acid of heat-storing material, the illiteracy dawn is cured, crystal is cured and B11 according to above-mentioned ratio of weight and number, under stirring, soaking condition, mix, be warming up to 85 ℃~175 ℃ under the normal pressure, add fire retardant, hydrophober, pour point depressant, stain control agent, mould inhibitor and the cement intensifier of adjusting material under constantly stirring successively, the reaction times is 6~8 hours; After under constantly stirring, being incubated 3~6 hours, be warming up to 300~320 ℃, kept 5~10 minutes, when waiting to be down to the temperature that is suitable for dressing, by being finished product behind the dressing machine dressing.
The selected cement intensifier of the present invention is to be with number of patent application : 200610047312.3For raw material.
Principle of work of the present invention is: utilize natural inorganic mineral matter shale and pitchstone to select it can the expanded absorption storage of solar energy of lightweight (calorific potential), it can discharge energy again as the supplemental heat source material of regulating room temp when environment change, and is not subjected to the luminous energy that influences sun power of overcast and rainy mist directly to penetrate the complete earth surface that is radiated of atmospheric layer again to be absorbed by the mineral substance heat-storing material and store the low-carbon energy-saving heat accumulating dry powder of producing the supplemental heat source material that is applicable in the building trade again through the present invention.
When the phase-change thermal-storage material was heated (thermals source such as sunlight, electric heating, hot water, hot blast), the temperature that reaches capacity (being transformation temperature) became liquid phase, and thermal energy storage is got up; When outside temperature was lower than design temperature (transformation temperature), phase change heat storage material began release of heat, and the heat release phase change material that finishes becomes solid phase by liquid phase, and circulation goes round and begins again.
Solar radiation wavelength 0.38~0.76 μ m, can be mapped to earth surface, and the rotation of the earth and around the oval-shaped orbital motion of the sun, the distance of the sun and the earth is a variable, its energy everywhere identity distance from and change, sunlight wavelength 0.3~3 μ m ray heat energy maximum, its storage heat energy of phase change heat storage material is the highest, the corresponding radiation quantity 604W/m of sunlight 2Shared per-cent 47%(visible light), when phase change heat storage material be coated with touch exterior wall after the ratio of its accumulation of heat time and heat release time be a constant, be that an equivalent correction yarn is counted δ=0.33~0.266 according to test result, phase change heat storage material is only measured its numerical value under steady state, and the heat conduction yarn of real phase-transition heat-storage is counted δ * λ (stationary value of phase change heat storage material), i.e. equivalent heat conduction yarn number.
Application purpose of the present invention provides a kind of exterior wall of novel energy-conserving lightweight, and interior wall phase-change thermal-storage material is incorporated in concrete, the mortar and can stores heat, and reaches heat preservation energy-saving 65%, reduces cost, improves operating efficiency, economical with materials thereby reach.
