Description
Technical field
The present invention relates to a kind of structure material, be specifically related to a kind of true mineral varnish of fire prevention with reflective insulation effect.
Background technology
True mineral varnish is low in resources consumption, be easy to construction upgrade, without potential safety hazard, color and wide in variety, be building coating research in recent years the most active, develop a direction the most rapidly.In recent years, along with the development of technology and the growth increasingly of energy consumption, energy-saving and emission-reduction have become the theory of housing design, will become inexorable trend for true mineral varnish application reflective insulation technology.
Vermiculite, as a kind of important nonmetal mineral resource, has the very abundant mineral deposit amount of accumulateing in China, due to swelling property good when its distinctive laminated structure and high-temperature calcination, makes expanded vermiculite not only itself have lower thermal conductivity and volume density.The scale structure energy reflective thermal radiation of its particle surface uniqueness, is the lagging material that a kind of potential using value is high simultaneously.But heat insulating material of vermiculite is generally recycle after directly utilizing raw ore or first high-temperature calcination to make it expand at present, major applications is at metallurgical, building materials field, and working method is very simple, and Application Areas is narrower.How energy saving building exterior coating has made full use of these inexpensive lagging materials, and this is be the opportunity of coatings enterprises, is again the challenge of coatings enterprises.
Primary mineral of vermiculite particle is utilized to emerge in an endless stream with the technology of heating expanded vermiculite for the building external paint of adiabatic heat-insulation, but the characteristic that the thermal conductivity that all only make use of vermiculite or vermiculite in flake is low.Most reflective insulation materials is all the titanium dioxide with strong covering power, or hollow glass micro-ball, but the price of both is all high, is unfavorable for wideling popularize, and is unfavorable for sustainable development because mineral resources is limited or energy consumption is excessive simultaneously.
Application number is nanostructure intermediate and the complexometry technique thereof that the Chinese invention patent of CN201110149508.4 discloses a kind of reflective insulation material, by adding the nano-metal-oxide of complexing agent complexes in coating, thus reaches the object of reflective insulation.Such as, but its nano metal oxide materials used is expensive, and the price of titanium dioxide raw material is exactly more than 10 times of vermiculite raw material, and it is high to produce nano-metal-oxide cost, and energy consumption is large.
The technology of micro-scale that preparation radius-thickness ratio is controlled and the technology comparative maturity of the micro-scale radius-thickness ratio of measurement.As document (Zhang Jingyang, Zhao Huang, Wu Weiduan. the development [J] of the superfine modified sericite slice of high radius-thickness ratio. Huaqiao University's journal, 2005,26(1), 51-53 .) disclose one supersonic jet mill legal system for the superfine modified sericite slice of high radius-thickness ratio.And for example application number is the method that the Chinese invention patent of CN201410057136.6 discloses the kaolinic preparation of a kind of high radius-thickness ratio and radius-thickness ratio measuring and calculating thereof, by kaolinite sheet layer material through intercalation, alcohol wash, lift-off processing, spraying dry, obtains kaolinite lamella sample.The structure of the structure of vermiculite and kaolinite and sericite is closely similar, and the development stage of product obtains the expanded vermiculite sheet of Different Diameter thickness rate by same technology.
