Description
Technical field
The present invention relates to the preparation method of a kind of biomass energy-storage thermal-insulating tile, belong to construction material preparation field.
Background technology
Tile be human occupancy must use basic building block, its effect is rainproof and heat insulation, it can through expose to the sun and rain and for many years
Not bad.And plain tiles just seems less desirable on effect of heat insulation, particularly directly accept burning sun summer and tan by the sun, Indoor Temperature
Degree is spent up to 40 more, and the room temperature of lower floor differed for ten several years.Thus, the resident living in top layer day and night will be by high temperature in summer
Scorch.Thin due to roofing to winter, poor thermal insulation property, thus tested by severe cold again, so it is desirable in roof room
Face can add the device of sunshading and thermal insulating.
Phase-change accumulation energy is a kind of important technology improving efficiency of energy utilization and protection environment of rising in recent years, can be used for
Solve the mismatch contradiction between heat energy supply and demand.When ambient temperature is too high, phase change material melts, and absorbs extraneous heat and works as
When external environment is too low, phase change material solidifies, outwardly heat release, thus reaches to control ambient temperature and energy-conservation purpose.
The most conventional phase-changing energy storage material mainly includes the inorganic and big class of organic phase change material two.Most inorganic phases
Change energy-storage material has corrosivity to building structure and has supercool and separated shortcoming in phase transition process, so limits
Its application.Organic phase change energy storage material non-corrosiveness, almost without supercool and separated shortcoming in phase transition process, and
Stable chemical nature, but common paraffin class organic phase change material is to obtain through non-renewable mineral oil, and fatty
Acids solid-liquid phase change material has natural reproducible, can extract, but the most easily reveal from biology, under high temperature easily
There is oxidation Decomposition and volatilization etc..
Summary of the invention
The technical problem that present invention mainly solves: functional single for current plain tiles, effect of heat insulation is undesirable, protects
Temperature poor performance, causes Summer Indoor temperature too high, and winter temperature is the lowest, and uses air-conditioning to regulate the room temperature and consume mass energy,
Do not meet the present situation of the modern life theory of energy-conserving and environment-protective, it is provided that the preparation method of a kind of biomass energy-storage thermal-insulating tile.Should
Method is with leaf fat as raw material, and aqueous alkali saponification after boiling, acid adding reduction prepares Adeps Sus domestica fatty acid mixed, itself and lauryl alcohol mixed
Emulsification pretreatment after conjunction, with emulsion dipping expanded perlite prepare energy storage filler, be aided with other raw materials compressing after i.e. obtain life
Material energy-storage thermal-insulating tile.The present invention prepares the organic solid-liquid phase change material of fatty acid with bio oil for raw material, is entrained in tile slurry
Material is made thermal insulation tile, loads phase-change material with expanded perlite, solve fatty acid solid-liquid phase change material and hold in use
Easily reveal, oxidation Decomposition and the defect of volatilization easily occur under high temperature, and utilization is entrained in phase-change material in tile and absorbs the sun
, there is solid-liquid phase change, got up by heat storage in the heat of light, it is to avoid heat improves indoor temperature, to evening through tile
Temperature reduce, again can by daytime store heat release, it is to avoid indoor temperature at night is too low, thus reach control ambient temperature and
Energy-conservation purpose, compensate for again the deficiency using air-conditioning to bring mass energy to consume, is the new product of a kind of environmental protection and energy saving.
