Description
Technical Field
The invention relates to the technical field of coatings, in particular to a heat-insulating nano composite coating and a preparation method thereof.
Background
In most areas of China, the temperature difference is large all the year round, hot summer and cold winter. But the heat insulation performance of the wall body of the prior building is not good. Air-conditioning refrigeration is generally adopted in summer, so that heat loss is caused, and energy waste is caused. In addition, air conditioners and other electrical appliances are adopted for heating in winter, and the indoor air temperature is easy to dissipate. Therefore, it is very important to research a coating with good heat insulation performance.
The basic components of the conventional coating on the market comprise pigments, dyes, solvents and fillers, and the other properties of the coating are usually achieved by adding the fillers. There are a number of inherent disadvantages that are difficult to solve. If inorganic ceramic particles such as titanium dioxide are used as fillers, the addition of titanium dioxide alone causes embrittlement of mechanical properties and poor coating coverage. For example, the content of inorganic ceramic particles is reduced, and the addition ratio of the resin binder is increased, so that the cost can be reduced, the coating coverage rate can be improved, and the mechanical property embrittlement can be avoided, but the heat insulation performance of the coating can be affected.
Therefore, the development of a novel heat-insulating composite coating is urgent.

The heat-insulating property of the heat-insulating nano composite coating is greatly enhanced, the problems of poor model property and coating coverage rate of the coating are solved, and the durability, the corrosion resistance and the strength of the coating are improved.
The purpose of the invention is realized as follows: a heat-insulating nano composite coating is composed of the following raw materials in parts by weight: 25-50 parts of aqueous curing agent and 50-100 parts of mother liquor of aqueous epoxy composite coating, wherein the mother liquor of the aqueous epoxy composite coating is obtained by adding gadolinium zirconate nano-powder and cellulose aerogel serving as fillers into a mixed solution of water and aqueous epoxy resin.
The water-based curing agent is Aq419, H228B, W651 or W650.
A preparation method of a heat-insulating nano composite coating comprises the following steps.
a. Preparing gadolinium zirconate powder by a coprecipitation method: taking 5-10 parts of gadolinium oxide (Gd)203) 8-17 parts of zirconium oxychloride (ZrOCl)2·8H2O)，ZrOCl2.8H2Dissolving 0 in 20-30 parts of ammonia water, reacting to obtain white flocculent precipitate, washing with anhydrous ethanol and deionized water for 5-10 times, and dissolving in 20-30 parts of HN03To obtain solution one, i.e. ZrO (N0)3)2A solution; gd is added203Dissolving in 5-10 parts of nitric acid to obtain solution II, Gd (N0)3)3A solution; mixing the obtained solution I and solution II to obtain mother salt solution with cation concentration of 0.05-0.07 mol/L, and dripping into solution with concentration of 22-25% ammonia water to obtain precipitate, aging for 24-48 h, filtering, drying in an oven at 50-70 deg.C, grinding, sieving, and calcining in a muffle furnace at 500-1000 deg.C for 4-6h to obtain Gd2Zr2O7And (3) nano powder.
b. Preparing cellulose aerogel: adjusting the pH value to 4-5 with hydrochloric acid in a beaker containing 10g-151.4% -1.6% of cellulose microfiber suspension, stirring for 2-4 h at the rotation speed of 500-600rpm and the temperature of 25-27 ℃, and freeze-drying a sample to prepare the cellulose aerogel.
c. Taking the prepared gadolinium zirconate nano-powder and cellulose aerogel, ultrasonically vibrating for 2-4 h at the vibration frequency of 100-200 Hz, taking out, putting into a vacuum drying oven at the temperature of 60-80 ℃ for 30-60 min, and obtaining the heat insulation nano-composite material; taking 10-40 parts of the heat-insulating nano composite material as a filler, adding the filler into a mixed solution of 100-200 parts of water and 100-200 parts of water-based resin, and dispersing the mixture in a ball mill for 1-2 hours to obtain a mother solution of the water-based epoxy composite coating.
d. Uniformly mixing 25-50 parts of water-based curing agent and 50-100 parts of water, and mixing with the mother solution of the water-based epoxy composite coating according to the proportion of 1: mixing at a ratio of 3-4.
The water-based epoxy resin in step c of the method is Ar555 epoxy resin, or H228A epoxy resin, or E44 epoxy emulsion, or E51 epoxy emulsion, or E20 epoxy emulsion.
Compared with the prior art, the invention has the advantages and effects.
The gadolinium zirconate nano powder adopted by the invention has a defect fluorite structure, and each Gd2Zr2O7And an oxygen vacancy exists in each unit, so that the thermal conductivity is lower compared with that of the traditional thermal insulation filler, and the thermal insulation effect of the coating is better. However, only gadolinium zirconate is added, which not only causes embrittlement of mechanical properties but also results in poor coating coverage. However, if the amount of gadolinium zirconate added is reduced, the mechanical properties are improved and the coating coverage is increased, but the thermal insulation properties of the coating are impaired. The invention adopts the combination of the cellulose aerogel and the gadolinium zirconate, improves the mechanical property and increases the coverage rate of the coating. Compared with the traditional aerogel, the cellulose aerogel also has the biological regeneration functionThe performance, biocompatibility and biodegradability are ecological and environment-friendly.
The invention provides a preparation method of a water-based epoxy composite heat insulation coating, wherein the used filler is gadolinium zirconate powder and cellulose aerogel which are compounded to form heat insulation nano powder, and the gadolinium zirconate powder has high heat insulation property and low heat conductivity, so that the heat insulation effect of the gadolinium zirconate powder is greatly enhanced. The cellulose aerogel overcomes the defects of mechanical property of the coating caused by inorganic filler. And the cellulose aerogel does not damage the environment.
