Abstract

The invention relates to a coating for photo-thermal reflection and photo-thermal isolation, and in particular relates to a preparation method of slurry special for modified floating beads, and the slurry special for the modified floating beads, belonging to the technical field of building coatings. A reflective thermal-insulation coating comprises a reflective coating and modified floating beads, wherein the modified floating beads are uniformly dispersed in the reflective coating. From economic considerations, ceramic hollow micro beads are replaced by fly-ash floating beads, and good technical effects are obtained; the price of the fly-ash floating beads is much lower than that of the ceramic hollow micro beads; and although the fly-ash floating beads have strong thermal insulation capacities, the color of the fly-ash floating beads is not pure white enough, and the photo-thermal reflection performance of the coating is influenced. According to the slurry disclosed by the invention, the color problems of the floating beads are solved by adopting a titanium dioxide spraying process; moreover, the adhesion of the floating beads to the wall surface is much stronger than that of the ceramic hollow micro beads, thus having technical advantages; the reflective coating disclosed by the invention not only can be used independently, but also can be matched with the modified floating beads; and the reflective coating has a photo-thermal reflection effect when being used independently, and has a reflective thermal-insulation effect when being matched.

Description

Modification is floated preparation method and the modification of pearl special sizing agent and is floated pearl special sizing agent
Technical field
The present invention relates to a kind of coating that reflects photo-thermal and isolated photo-thermal, be specifically related to modification and float preparation method and the modification of pearl special sizing agent and float pearl special sizing agent, belong to building coating technical field.
Background technology
Current, reflective heat-insulation paint has obtained applying more and more widely under construction.In general, the reflective insulation effect of reflective heat-insulation paint, under same base material strip part, color stuffing plays leading role, and wherein filler is the important component part of coating, is one of key of preparation high-level efficiency reflective heat-insulation paint to its selection.The empty microballon of pottery is a kind of white meal, and its granule interior is hollow, and density is low, and thermal conductivity is little, the incident waves such as the fine reflected light of energy, heat, and the slow heat energy of resistance conducts to interior of articles, and these performances make it to become the first-selected filler of reflective heat-insulation paint.The preparation of current reflective heat-insulation paint, selects this type of filler mostly, but the high-quality ceramic hollow microballon of all size still be take import as main, and its price is generally higher, larger to coating material production cost impact.
From flyash, can extract the fly ash float that obtains being similar to ceramic fine bead, its outward appearance is greyish white meal, granule interior is hollow, density is low, thermal conductivity is little, with ceramic fine bead comparison, its thermal resistance effect performance approaches, but because surface color is darker, during as filler, in coating along with the increase of its add-on, coating color is deepened rapidly, have a strong impact on the effect of the reflection photo-thermal of filming, conventionally in coating preparation process, must be by strong covering power, refractive index is large, the titanium white powder pigment collocation that whiteness is high is used, and suitably strengthen consumption, effectively to hide the color and luster that floats pearl, this adjustment to formulation for coating material has certain limitation.According to the study, in the composition of reflective heat-insulation paint, filler fly ash float proportion is within the specific limits along with the continuous increase of its add-on, the heat rejection thermal characteristics of coating improves gradually, but coating color is also deepened thereupon, coating is filmed and more easily absorb photo-thermal, greatly affect the reflective insulation function of coating.
For addressing this problem, there are some researches show, the titanium dioxide with high refractive index, high whiteness is coated in advance and floats bead surface, make to float the titanium dioxide crystal phase structure tectum that pearl particle has high refractive index.The pearl that floats through upper method modification combines thermal resistance reflection dual property, and the filler as preparing reflective heat-insulation paint, can effectively strengthen the reflective insulation performance of filming.
Existing report titanium salt hydrolysis coating method, is about to particle and is suspended in certain medium, controls the processing condition such as pH, temperature, concentration, makes titanium salt be hydrolyzed into TiO 2deposit to particle surface, after hydrolysis reaction proceeds to a certain degree, filtration, washing, oven dry, roasting, obtain product.As the Chinese invention patent that application number is 02156763.8, a kind of surface TiO of tourmaline powder is disclosed 2coated modifying and whitening method, comprises the following steps: (1) adds water slurrying by tourmaline powder, and pulp quality is than being tourmaline powder: water=1:6~15; 0.1%~1.0% the SnCl that simultaneously adds tourmaline powder weight 2or ZnO; Add acid-conditioning solution pH to 1.5~3.5; (2) tourmalinite slip is heated to 55~95 ℃, adds titanium salt solution, add NaOH or urea soln simultaneously, take and keep slip pH as 2.5~3, in reactor or retort, tourmaline powder is carried out to surface TiO 2precipitation coating reaction, the reaction times is 2~6h; (3) coating reaction product filtered, wash, be dried and roasting.But preparation technology is more tired for this class Chemical coating method, and quality stability is not high, and production process energy consumption is larger.
