Description
Technical field
The present invention relates to a kind of building coating, specifically, relate to a kind of paint filler of coated by titanium dioxide fly ash float, the thermal insulating coating that utilizes this filler and their preparation method.
Background technology
Thermal insulating coating is a kind of novel functional coating.It can intercept effectively, reflection, radiation solar heat, reduce exterior wall surface and room temp, improve Working environment thereby reach, the purpose that cuts down the consumption of energy, thereby be widely used in fields such as external wall, boats and ships, vehicle, oil tank outer wall and military affairs, space flight.At present, according to conduction, convection current and three kinds of approach of radiation of conducting heat, people are divided into isolation-type, reflection-type and radiation type heat-insulation coating three classes with thermal insulating coating.
The material that the isolation-type thermal insulating coating is normally little with apparent density, internal structure loose, void content is high, water ratio is little is as light skeletal, rely on the binding agent effect that it is combined, directly be applied in the formation of equipment or surface of wall and have certain thickness thermal insulation layer, thereby reach the effect of heat-insulation and heat-preservation.The starting material of this coating are easily got, and production unit is simple, less investment, and output is big, easy construction, but it is thicker to reducing convection current and radiative transfer weak effect and thermal insulation layer, the water-intake rate height, work-ing life is short, and in order to form a stable heat insulation system, also need set up defences in addition water layer and protective layer.
Reflection type thermal insulation coating is by selection appropriate resin, metal or metal oxide pigment, filler and production technique, makes highly reflective coatint reflection solar heat, thereby reaches the purpose of heat insulation and heat control.This kind coating and various base material sticking power are good, have good close capacitive with priming paint, intermediate coat, and weathering resistance is strong, and effect of heat insulation obviously is better than the isolation-type thermal insulating coating.But present most of reflection type thermal insulation coating is solvent system, then requires to promote and use water-borne coatings in the current building coating.
