Description
Technical Field
The invention relates to the technical field of heat insulation coatings, in particular to a transparent heat insulation coating with a microstructure and a preparation method and application thereof.
Background
Sustainable development and green development are mainstream of future development, and reducing energy consumption and saving energy are main measures of sustainable development and green development in China. The energy consumption of China in the building industry accounts for about 35 percent of the total consumption of China. In summer and winter, the use of air conditioners and heating accounts for 40% of the energy consumption of a building. In order to reduce energy consumption, a layer of transparent heat insulation coating can be coated on the building glass and the outer wall, the transparent heat insulation coating effectively reduces the temperature and reduces the thermal sensation brought by infrared light, and therefore the use of an air conditioner is reduced.
The heat insulation principle of the existing transparent heat insulation coating is to reflect near infrared light and reduce the heat effect of the infrared light, but the visible light transmittance of the existing transparent heat insulation coating is still low. Meanwhile, the thickness of the transparent heat insulation coating is too thin, so that the near-infrared reflection effect is reduced, and the heat insulation effect is influenced; the thickness of the transparent heat insulation coating is too thick, and the visible light transmittance is reduced. However, glass is adopted in many buildings in China, the low visible light transmittance can affect the appearance and reduce the utilization of solar energy, and particularly when the glass is applied to photovoltaic power generation, the low visible light transmittance can affect the photoelectric conversion efficiency.
In view of this, the invention is particularly proposed.
Disclosure of Invention
The invention aims to provide a transparent heat insulation coating with a microstructure, and a preparation method and application thereof.
The invention provides a preparation method of a transparent heat insulation coating with a microstructure, which comprises the following steps:
s1: mixing deionized water, a dispersing agent and nano powder, and then carrying out ball milling to prepare slurry;
s2: mixing the slurry with a UV curing agent, and then carrying out ball milling to prepare a coating;
s3: and coating the coating on the substrate by adopting a wire rod with a microstructure, and curing and forming to obtain the transparent heat-insulating coating with the microstructure.
In the invention, the nano powder can be prepared into a coating by uniformly dispersing the nano powder which is low in price, can transmit visible light and can shield near infrared light, and the visible light can be effectively transmitted and the near infrared light can be effectively reflected. Specifically, the materials for shielding the visible light high-transmittance near-infrared light can be cesium tungsten bronze, indium tin oxide, nano ATO and the like, and the materials have the characteristics of high visible light transmittance and near-infrared light reflection; the nano ATO is relatively low in price, good in visible light transmission performance and not easy to generate heat accumulation, so that the nano ATO is preferably used as the nano powder. The particle size of the nanopowder is not particularly limited, and may be, for example, 40 to 60nm.
The uniform dispersion of the nano powder is an important index for preparing the slurry, and if the nano powder is not uniformly dispersed, the slurry is agglomerated, and the transmittance of visible light is affected. The preparation method adopts a mode of combining physical dispersion with chemical dispersion to prepare the slurry with uniform distribution, wherein the physical dispersion is dispersed by a ball mill, the chemical dispersion is dispersed by a dispersing agent, and the dispersing agent can adopt a silane coupling agent, such as a silane coupling agent KH560 and the like. Adding the nano ATO powder, deionized water and a silane coupling agent KH560 into a ball milling tank, starting a ball mill for ball milling, and preparing the slurry with uniformly dispersed nano ATO powder.
During ball milling, the dosage proportion of deionized water, a dispersing agent and nano powder can be controlled to be (140-160) mL: (5-10) g: (1-3) g. In addition, ball milling can be carried out by adopting ball milling beads with the diameter of 0.1-0.3mm, and the ball-to-material ratio can be controlled to be (6-8): (2-4), the rotating speed is 400-500r/min, the ball milling time is 4-6h, and the material of ball milling beads can be zirconium dioxide and the like; wherein, the ball material ratio refers to the volume ratio of the ball milling beads to the mixed material of the deionized water, the dispersant and the nano powder.
In the present invention, a UV curing agent having transparency and high visible light transmittance, for example, a UV curing agent K2018 or the like, may be selected. The curing agent has excellent wear resistance and acid and alkali resistance, and the prepared coating is tough, firm in bonding and high in visible light transmittance; meanwhile, the UV curing agent K2018 can be used for glass, and the UV curing agent K2018 and the slurry are placed into a ball milling tank for ball milling to obtain the coating. During ball milling, the volume ratio of the slurry to the UV curing agent can be 1: (1.5-2.5), in addition, ball milling beads with the diameter of 0.1-0.3mm can be adopted for ball milling, and the ball-to-material ratio can be controlled to be (6-8): (2-4), the rotating speed is 400-500r/min, the ball milling time is 4-6h, and the material of the ball milling beads can be zirconium dioxide and the like.
In the present invention, an optical glass which is inexpensive and has high transmittance in visible light can be selected as the substrate. In order to make full use of sunlight and have a better visible light transmittance, optical glass having a high visible light transmittance may be selected as the substrate. Since the high and low transmittance of visible light directly affects the utilization efficiency of sunlight, in order to fully utilize sunlight, the substrate may be optical glass K9 or optical glass BK7, which has high hardness, good scratch resistance and high transmittance of visible light, and preferably optical glass BK7.
In the present invention, the microstructure may be a V-groove microstructure; preferably, the vertex angle of the V-shaped groove microstructure can be 60-80 degrees, and the structure period is 25-35 μm. Specifically, a CNC (computerized numerical control) precision grinder can be used for processing an array V-shaped groove microstructure on a bar, and the processed microstructure bar is polished and cleaned for later use.
The invention also provides a transparent heat insulation coating with a microstructure, which is prepared according to the preparation method.
The invention also provides application of the transparent heat insulation coating with the microstructure in building glass or an outer wall.
The transparent heat insulation coating has a microstructure, the microstructure has a good antireflection effect, and the transmittance of visible light can be effectively increased; the existing microstructure coating preparation process usually adopts a nanoimprint method to carry out repeated etching, and transfers the microstructure on a template to a material to be processed by the assistance of photoresist, and the processing method has extremely high requirements on processing equipment and relatively expensive processing cost; the microstructure is processed on the wire rod, the special coating is coated on the substrate by the wire rod with the microstructure for film coating processing, the transparent heat insulation coating with the microstructure can be obtained, and the microstructure coating is irradiated by the UV curing lamp for curing, so that the transparent heat insulation coating with the microstructure can be prepared.
