Abstract
The invention discloses a kind of high-heat energy-saving heat preserving building coating, its component and content are according to percentage by weight, as follows respectively：The nano silicon oxide 15～40% of interior closed pore external-open pore structure, nano-titanium oxide 4～10%, potassium hexatitanate 1～10%, Titanium pyrophosphate 1～10%, magnesium silicate 3～15%, aluminium hydroxide 1 3%, sodium metasilicate calcium 1～3%, acrylic acid composite emulsion 2～18%, function additive 1.5～3%, remaining is water.The invention also discloses corresponding preparation method.The coating of the present invention adopts the microstructure design of micrometer/nanometer macrostructure, heat transfer approach is controlled with the table/interface in micrometer/nanometer macrostructure, shell, within closed pore, the interior ultra micro closed pore negative space of the nano oxidized silicon composite of external-open pore structure realize heat-insulation and heat-preservation, exterior open cell body structure surface activity is very strong, the multidimensional network that can be formed between particles, as the carrier of temperature control phase-change material, realizes temperature adjustment function.
Description
Technical field
The invention belongs to building heat insulation field of material technology is and in particular to a kind of high-heat energy-saving heat preserving building coating
And preparation method thereof.
Background technology
Feature heat-insulated (thermal resistance) coating was 20 century 70 Global Oil times of crisis, and European countries are to alleviate the energy
Problem and the product of once large-scale policy sex work that launches.U.S.'s adiabator for building since 1987 accounts for all
The 81% about of adiabator.In AND ENERGY RESOURCES CONSUMPTION IN CHINA, building energy consumption constitutes about the 1/4 of national energy resource consumption total amount, and builds
Only account for the 11% about of total amount with adiabator.Building energy consumption proportion in the whole energy resource consumption of the mankind is very high, builds energy
Consumption in the whole energy resource consumption of the mankind proportion typically in the energy consumption of 30-40%, mostly heating and air-conditioning, therefore building
Energy-saving significance is great, is the fundamental way solving China energy problem, and building energy conservation the most effectively method be using protecting
Warm heat-barrier material.In architectural reasonable employing heat preserving and insulating material, it is possible to reduce the consumption of construction material, improve construction
Industrialization degree, accompanied by substantial power saving.
Traditional building heat insulation material organic heat-insulating heat-preserving material such as hard bubbles for such as EPS sheet, XPS plate, PU, at present
The organic insulation material that China adopts occupies more than the 80% of industry and building heat preservation engineering share.Although these organic heat-insulatings
Material has that heat conductivity is excellent, good heat insulating advantage, but their fire protecting performance is poor, easily causes fire disaster
Accident.Because the contradiction of Conventional insulation inflammability and heat-insulating property does not have essence to solve, thus leading to the fire-fighting taken
Measure can only be the passive fire preventing mode such as setting isolation strip it is impossible to be inherently eliminated disaster hidden-trouble.Secondly, existing have
Organic insulation material (as polyphenyl, polyurethane, extruded sheet etc.) toxic is seriously polluted, volatilizes big during production and use
The abnormal flavour of amount and toxic gas, cause the severe contamination to industrial environment and social environment.In addition, existing insulation material
Fundamentally do not solve to control heat source factor in environment, belong to a kind of passive type determining heat-insulating property with material character
Intercept heat preserving method.
Inorganic heat insulation material is also widely used under construction, for example rock wool, mineral wool, glass cotton, foam concrete, vitreous
The inorganic heat insulation materials such as microballon, although combustibility reaches A level, have good flameproof effect, and ageing resistace is stable and wall
Basic unit and float coat combine preferably, safety and firmness is good, heat-insulation layer intensity and durability is higher than organic insulation material, service life
Length, difficulty of construction are little, engineering cost is relatively low, and eco-environmental prote is good, can be with cycling and reutilization.But due to inorganic heat insulation material
Heat conductivity is poor, and heat-insulating property is not good enough, is extremely difficult to preferable heat insulation heat preservation energy-saving effect, or even meets water inefficacy.For section
The building more than 65% can be required, the design thickness of inorganic heat-insulating layer will exceed 50mm it is impossible to use, and cost is high.
Water nano heat-insulating heat-preserving material is occurred in that, by inorganic nano material and inorganic heat-insulating material in prior art
Compound, it is equipped with film forming and function additive, the adjustable heat-insulating heat-preserving material of thermal property can be prepared.This active thermal heat preservation energy-saving
