Abstract
The invention discloses a composite heat insulating material which comprises a heat insulating layer and a surface covering layer covering the outside of the heat insulating layer. The heat insulating layer comprises raw materials including, by weight, 10-25 parts of volcanic ash and 75-90 parts of environmental protection glue, wherein the environmental protection glue is formed by mixing 100 parts of water with 6-10 parts of polyvinyl alcohol. The surface covering layer is a nano ceramic film. The composite heat insulating material has a remarkable heat insulating effect, resists high temperature, cannot burn at the temperature higher than 1200 DEG C, has an ultra-strong self-cleaning capacity, is long in service life, can replace a traditional heat insulating board, and is widely applied to the fields of building coating protection, petrochemical industry, natural gas transport, municipal bridges, automobiles, household appliances, ventilating ducts and the like.
Description
Technical field
The present invention relates to a kind of heat insulating material, be specifically related to a kind of high temperature resistant, super self-cleaning compound insulating material.
Background technology
Along with implementation and the development of building energy conservation, heat insulating material and goods are more and more subject to people's attention.Organic insulation material is polyphenyl plate, extruded sheet, poly-ammonia plate etc. mostly at present, although this class material can reach good heat-insulating property, but the drawback of its existence as: (1) traditional heat preservation technology all belongs to the thin measure of plastering, and this class material non-refractory, very easily causes disaster hidden-trouble; (2) polyphenyl plate, extruded sheet are easy to occur bubbling, cracking and obscission, and application life is short, and later period maintenance is taken high; (3) intensity is low, and surface is easily destroyed, affects outward appearance.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide the compound insulating material of remarkable, high temperature resistant, super self-cleaning, the long service life of a kind of heat insulation effect.
A kind of compound insulating material of the present invention, comprise insulation layer and cover its outside surface coating, described insulation layer, by mass parts ratio, comprises following raw material: 10 ~ 25 parts of pozzolan, 75 ~ 90 parts, environmental protection glue, described environmental protection glue is that the polyvinyl alcohol by 100 parts of water and 6 ~ 10 parts mixes and forms; Described surface coating is nano ceramics film.
Preferably, the mass fraction of described each raw material of insulation layer is: 15 ~ 20 parts of pozzolan, 80 ~ 85 parts, environmental protection glue.
Compound insulating material of the present invention, the thickness of described insulation layer is 1.0 ~ 2.5mm, the thickness of described surface coating is 0.5 ~ 1.5mm.
For further meeting needs attractive in appearance, the present invention can be at the outside coverage pigment layer of surface coating.
The present invention adopts homemade environmental protection glue, and the preparation method of described environmental protection glue comprises the steps: after the water boil of 20 ~ 40 parts, to add 6 ~ 10 parts of polyvinyl alcohol, continues heat and stir, after polyvinyl alcohol all dissolves, add again remaining water, continue stirring and be warming up to boiling, obtain environmental protection glue.
Preferably, the preparation method of described environmental protection glue comprises the steps: after the water boil of 30 parts, to add 7 parts of polyvinyl alcohol, continues heat and to stir, after polyvinyl alcohol all dissolves, then adds the water of 70 parts, and continuation stirring is warming up to boiling, obtains environmental protection glue.
Pozzolan of the present invention refers to by volcanic eruption to go out and rubble and mineral matter particle that diameter is less than 2 millimeters.It has pozzolanic activity, at normal temperature with have water in the situation that, can react with lime (CaO) hydrate that generation has hydraulicity gelling ability.Pozzolan is comprised of rock, mineral, volcanic glass fragment, exists active silica, the activated alumina isoreactivity component of some.
Nano ceramics film of the present invention is a kind of pure inorganic coating material of environmental protection, semipermanent with pottery and plastic deformation ability.Its initial feed is silica, the nano level processing of process and a series of polymerization-condensation, hydrolysis, and the C inside having removed and H etc. are organic elements all, finally become and take Si-O key as main pure inorganic substances.It has the characteristics such as acid and alkali-resistance, super weather-proof, high temperature resistant 1200 ° of C do not burn above, super self-cleaning, asepsis environment-protecting.
Compared with prior art, the present invention has following beneficial effect,
1) adopt GB/T10297-1998 standard to test the coefficient of thermal conductivity of material of the present invention, its coefficient of thermal conductivity is only 0.036, heat-insulating property is extremely good, and there is good acid-alkali-corrosive-resisting, experiment test 168h is without extremely, and has superelevation weatherability, simultaneously because the pozzolan raw material source adopting is abundant, cost is lower, and its weight is lighter;
2) the present invention is at the outside covering surfaces covering layer of insulation layer, and its surface coating adopts special nano ceramics film, makes insulation
Material is high temperature resistant, and 1200 ° of C do not burn above, and have superpower self-cleaning ability, long service life, and alternative traditional warming plate, is widely used in the fields such as building painting is protected, petrochemical industry, natural gas transmission, municipal bridge, automobile, household electrical appliances, ventilating duct.
