Abstract
The invention discloses a rice husk ash phase-change energy-storing thermal insulation material. The rice husk ash phase-change energy-storing thermal insulation material is mainly formed by mixing rice husk ash, expanded perlite, fly ash, waste diatomite, silica fume, cement, phase-change thermal insulation material PCM, moisture-proof agent, sodium carboxymethyl cellulose and foaming agent according to a certain mixing proportion. The rice husk ash, the waste diatomite, the fly ash and the silica fume are wastes produced by the grain processing industry, the chemical industry and the metal smelting industry. The utilization of the wastes can not only protect the environment, but also reduce the production cost. The rice husk ash has high and low temperature resistance, good compression strength and light weight, the rice husk ash phase-change energy-storing thermal insulation material which is prepared by taking the rice husk ash as an aggregate has the functions of fire prevention, moisture protection, thermal insulation and temperature regulation, and the compression strength and the thermal insulation performance of the rice husk ash phase-change energy-storing thermal insulation material are better than those of the traditional expanded perlite and the thermal insulation material of the extruded plate, thereby overcoming the conflict between the thermal insulation performance and the compression strength of the traditional thermal insulation material and further solving the difficult problems of surface layer cracking and tile shedding of the thermal insulation material. The rice husk ash phase-change energy-storing thermal insulation material is applied in a maintenance structure of a building for thermal insulation, thereby improving the living comfort, simultaneously having the comprehensive advantages of sound proof, energy conservation, environmental protection and the like, and providing a new reliable way for energy conservation of the building.
Description
Technical field
The present invention relates to the energy-saving building technology field, relate in particular to a kind of rice husk ash phase-change energy-storing thermal insulation material.
Background technology
Along with The development in society and economy and growth in the living standard, people are also more and more higher to the requirement of indoor environment comfort level, air conditioning energy consumption increases thereupon significantly, causes that energy consumption is too fast, environmental pollution increase, network load peak-valley difference are excessive, problem such as supply of electric power wretched insufficiency during the peak load.Energy-conserving and environment-protective work is more and more paid attention in countries in the world, and China has made and issued a series of energy-conserving and environment-protective policies, promotes the development of energy-conserving and environment-protective new material industry.The tradition lagging material only has single resistive properties, does not have the energy-saving and temperature-regulating function.Because phase change material has the performance that absorbs or discharge heat energy in the change process of its form, by the building energy saving field widespread use.Rice husk ash phase-change energy-storing thermal insulation material utilizes phase-changing and temperature-regulating mechanism, and the phase-state change by energy-accumulating medium realizes thermal energy storage and release, thereby improves indoor thermal cycling quality.When envrionment temperature was lower than certain value, phase change material was condensed into solid-state by liquid state, release of heat; When envrionment temperature was higher than certain value, phase change material absorbed heat by the solid-state liquid state that is molten into, and makes the room temperature relative equilibrium.Phase change material can be collected unnecessary heat, discharges in good time steadily, and graded is little, the effective amount of reducing the wastage, and room temperature can tend towards stability.Rice husk ash phase-change energy-storing thermal insulation material utilizes phase-changing and temperature-regulating mechanism, can make electric load " peak clipping Pinggu ", makes full use of the low ebb electricity price, reduces resident family with (consumption) energy cost, reduces energy dissipation.Particularly to improving the room temperature of the first floor, top layer, edge living environment, summer, heat insulation, Winter protection all can play poising action.New building decorate and old building transforming in, rice husk ash phase-change energy-storing thermal insulation material can overcome congenital defect disadvantages such as cracking of wall surface, dewfall, mouldy, peeling.Rice husk ash phase-change energy-storing thermal insulation material can the instead of clay solid brick, both digested the pollution of factory depleted rice hull ash, diatomite, silicon ash, flyash to environment, saved land resources again, rice husk ash phase-change energy-storing thermal insulation material has considerable social benefit and economic benefit.
Summary of the invention
Technical problem to be solved by this invention is, a kind of rice husk ash phase-change energy-storing thermal insulation material is provided, in order to solve the problem of traditional walling unit and the lagging material waste resource and the energy.
For solving the problems of the technologies described above, the invention provides rice husk ash phase-change energy-storing thermal insulation material, this rice husk ash phase-change energy-storing thermal insulation material is mainly stirred according to certain proportioning by rice hull ash, pearlstone, flyash, waste diatomite, silicon ash, cement, phase change heat storage material PCM, non-blushing thinner, Xylo-Mucine, whipping agent to be formed.Further, described rice hull ash, waste diatomite, silicon ash, flyash are the wastes of grain processing industry, chemical industry, Metal smelting industry, heat power plant's generation, and utilization of waste material both can be protected environment, can reduce production costs again.
Embodiment
According to weight proportion be: 100 parts of rice hull ash, 100 parts of pearlstones, 30 parts in flyash, 30 parts of waste diatomites, 15 parts of silicon ashes, 100 parts of cement, 60 parts of phase change heat storage material PCM, 10 parts of non-blushing thinners, 3 parts of Xylo-Mucines, 3 parts of whipping agents stir in stirred pot and promptly made a kind of rice husk ash phase-change energy-storing thermal insulation material until mixing in 30 minutes.
Above-mentioned materials pack is the rice husk ash phase-change energy-storing thermal insulation mortar,, is placed on that extrusion forming promptly makes rice husk ash phase-change energy-storing insulation blocks or member in the mould the water stirring of above-mentioned materials 100-150 part and 25-50 part 30 minutes.
