Description

A kind of environment protection architecture coating and preparation method thereof
Technical field
The present invention relates to building field, particularly relate to a kind of environment protection architecture coating and preparation method thereof.
Background technology
Along with the fast development of social production, the energy and environment become the two large problems that the whole society attractes attention day by day, thus propose higher requirement to energy saving standard.And the world generally faces the crisis of energy worsening shortages now, in order to reduce energy consumption, the every aspect that people live in social production is all had higher requirement to the service efficiency of the energy.Wherein at building field, energy saving building is the effective way improving building energy service efficiency.
Outside the building wall or interior wall spray coating heat preservation coating are means of building energy conservation, and its cost is low, easy construction.Traditional exterior wall or construction coating for internal wall mainly emphasize anticorrosion, antifouling, ageing-resistant, self-cleaning is good, but pay close attention to not in environmental-protecting performance and heat-insulating property.
China's building thermal-insulating coating grew up in late 1980s, wherein most widely used is barrier heat insulating coatings, such as " coating-type composite heat-insulating silicate material ", " compound silicate insulating paint ", " magnesium silicate insulating material ", " rare-earth thermal insulating coating " etc.Because this kind of coating needs high temperature resistant, thus generally organic base-material can not be used, but use can the inorganic silicic acid salt material of resistance to certain temperature, such as cement and water glass etc., add used filled insulation also mainly some silicates materials, such as fibrous magnesium silicate, pearlstone and sepiolite powder etc., thus this kind of coating is called as " quality silicate composite thermo-insulating thermal insulating coating ".Although composite silicate thermal insulation paint thermal conductivity is lower, cost is also low, and drying cycle is long, and impact resistance is weak, and dry shrinkage is large, and rate of moisture absorption is large, and cohesive strength is low, decorative effect is poor.
Another kind of thermal insulation coatings is reflective heat-insulation paint, and it is by selecting suitable raw material and formula etc., and obtained highly reflective coatint, reflected sunlight reaches heat insulation object.But the coating thickness of reflective heat-insulation paint is thinner, and entire thermal resistance is limited, heat insulation effect is still not enough to some extent.
For the various deficiencies that existing thermal insulation coatings exists, occurred nano heat-insulating thermal insulation coatings, it take synthetic resin emulsion as base-material, introduces that reflectivity is high, nano level reflective insulation material that thermal resistance is large and making, and the thermal conductivity of this coating is low and reflectivity is high.Therefore nano heat-insulating thermal insulation coatings one of focus becoming current research.Such as, but existing nano heat-insulating thermal insulation coatings still Shortcomings, have employed the virose solvent of tool.
