Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions will be clearly and completely described below in conjunction with the embodiments of the present application, and it is obvious that the described embodiments are a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The examples do not show the specific experimental steps or conditions, and can be performed according to the conventional experimental steps described in the literature in the field. The reagents or instruments used are not indicated by manufacturers, and are all conventional reagent products which can be obtained commercially.
The heat-insulating coating provided by the invention comprises alkyd resin, acetone, propylene glycol methyl ether, titanium dioxide, a leveling agent, a pigment dispersing agent, a sterilization mildew-proof agent and a light reflecting agent. The components are physically mixed according to corresponding mass ratio under corresponding conditions of normal temperature and normal pressure to obtain the heat-insulating coating.
The leveling agent may be polydimethylsiloxane, acrylic resin, or the like, and the application does not limit the specific choice of the leveling agent, including but not limited to any leveling agent in the prior art. The leveling agent can promote the heat-insulating coating to form a flat, smooth and uniform coating film in the drying film-forming process, and can reduce the possibility of generating spots and stains during coating.
The pigment dispersant can be polyacrylic acid sodium salt, polycarboxylic acid sodium salt and the like, and the application does not limit the specific selection of the pigment dispersant, and the pigment dispersant includes, but is not limited to, any pigment dispersant in the prior art. In the actual preparation process, the method can be selected according to the specific actual conditions. The pigment dispersant is used in the heat-insulating coating, so that the gloss of a coating film can be increased, the leveling property is improved, the coloring and covering power of the heat-insulating coating are improved, flooding and sedimentation are prevented, and the production efficiency and the storage stability of the coating are improved.
The fungicide and mildew inhibitor can be pentachlorophenol, benzimidazole or dithiocarbamic acid ester and the like, and the application does not limit the specific selection of the fungicide and mildew inhibitor, and the fungicide and mildew inhibitor comprises but is not limited to any fungicide and mildew inhibitor in the prior art. The sterilization mildew preventive can effectively control the propagation of microorganisms in the heat insulation coating, and ensure that the performance of the heat insulation coating is not changed.
The reflecting agent can be one or a mixture of a plurality of ceramic micro-beads, ceramic bubbles, borosilicate micro-beads, perlite, expanded pearls, shell powder, hollow glass beads or hollow micro-beads and the like.
When the reflecting agent adopts ceramic micro-beads or ceramic bubbles, the heat insulation coating contains extremely fine ceramic bubbles, so that the reflecting agent has higher reflectivity to sunlight, and the ceramic bubbles are closely arranged to form a complete heat insulation layer after being shaped into a magic cube, so that the internal temperature of a coated object can be greatly reduced, and meanwhile, the heat insulation performance is excellent, and the insulation and flow performance is good.
When the reflecting agent adopts borosilicate micro-beads, perlite, expanded pearl or shell powder, the refractive index of the borosilicate micro-beads is very close to that of most of powdered synthetic resin, so that the heat-insulating coating has higher transparency. Therefore, even when the amount of the addition is 20%, the transparency of the resin is not affected and the scratch resistance is high. The product has the effects of yellowing resistance, high temperature resistance and weather resistance, ultraviolet resistance and natural chalking resistance, the pH value is stable, and the product is processed at a low temperature without pollution and is subjected to multistage sectional screening, so that the cumulative peak with the narrowest particle size distribution is obtained. Therefore, the prepared heat insulation coating has high temperature resistance and high refractive index.
When the reflecting agent adopts hollow glass beads or hollow microspheres, the heat conductivity coefficient of the hollow microspheres is low, so that the heat energy can be effectively isolated from being transferred, and the external heat can be isolated from being transferred to the inside of an object even when the atmospheric temperature is high. Meanwhile, the prepared heat-insulating coating has self-cleaning capability and good finish.
When the paint is coated, the heat-insulating paint is sprayed on the surface of the outer wall, so that a layer of light-reflecting heat-insulating layer is formed on the surface of the outer wall, the light refractive index can be greatly reduced according to the light emission principle, and the purposes of energy conservation and heat insulation are achieved. Therefore, the heat insulation coating is coated on the surface of the outer wall, so that the wall can generate the temperature adjusting effect under the irradiation of sunlight.
Furthermore, the thermal insulation coating is obtained by manually mixing the components together at normal temperature and normal pressure and stirring uniformly, and the thermal insulation coating is convenient and quick without additional preparation. By the mode, the purposes of saving cost, saving energy and having high efficiency can be achieved.
After the heat insulation coating is coated on the surface of an outer wall, the thickness of the dried coating is 3mm-5 mm. When the paint in the prior art is coated, the thickness of the coated paint is about 30mm because the processes of adding a wall bonding interface agent, anti-cracking waterproof mortar, alkali-resistant fiber mesh cloth and the like are needed. Compared with the prior art, the heat-insulating coating has the advantages that the process is not required to be added in the coating process, so that the heat-insulating coating is thinner after being coated, the process steps are reduced, the coating period can be greatly shortened, and the cost can be reduced.
Further, the thinner the coating thickness of the thermal barrier coating, the better the reflection effect on sunlight. Preferably, the thickness of the coating after the thermal insulation coating is coated is 3mm-5 mm.
In order to ensure the light reflecting and heat insulating performance of the prepared heat insulating coating, the light reflecting agent is particles with a polyhedral structure, and the particle size of the light reflecting agent is 40-130 mu m. Because the particles of the light reflecting agent are smaller, the components are arranged more closely, and the ductility of the prepared heat insulation coating is improved.
Preferably, the light reflecting agent has a wall thickness of 1 μm to 2 μm, and in this state the light reflecting agent is relatively thin and the distribution between the components is more uniform. Also, particles with wall thicknesses of 1 μm to 2 μm perform better as the material itself than particles with wall thicknesses greater than 2 μm.
Preferably, the light reflecting agent is in a hollow form. Likewise, the light reflecting agent may also be in the shape of spheres, but the processing cost of the components in the shape of spheres is relatively high, and for cost reasons, it is preferred that the light reflecting agent be in the shape of a hollow polyhedron. The hollow form provides smaller gaps and provides more uniform distribution of the fluid to the standard than a spherical form of the retroreflective agent. The shape of the hollow polyhedron can achieve the effect of reflecting light, and the corresponding wall thickness can meet the effect of heat insulation.
Similarly, the light reflecting agent can also adopt particles which are in hollow polyhedral structures in other shapes in the prior art, the particle diameter of the particles is 40-130 μm, and the wall thickness of the particles is 1-2 μm. The specific components of the light reflecting agent are not listed in the application without influencing the use and coating after the preparation of the heat insulation coating.
The prepared heat insulation coating integrates reflection, radiation and heat insulation, so that the heat insulation coating can highly reflect solar infrared rays and ultraviolet rays within the range of 400nm-2500nm, does not allow the heat of the sun to be accumulated on the surface of an outer wall to rise in temperature, can automatically radiate the heat on the surface of the outer wall to the air to reduce the temperature on the surface of the outer wall.
When sunlight is strong, the heat-insulating coating can reduce the surface temperature of the outer wall by more than 20 ℃; the temperature can be reduced to be above 3 ℃ or to be consistent with the atmospheric temperature in cloudy days and at night.
Even heat insulating coating also can the radiant heat reduce temperature at cloudy day and night, the heat conductivity coefficient of the hollow bead in the heat insulating coating is extremely low simultaneously can completely cut off the transmission of heat energy, even also can keep outside heat to the inside conduction of wall body when atmospheric temperature is very high, has guaranteed heat insulating coating's cooling effect from this, has guaranteed that the outer wall is inside to keep lasting homothermal state.
Further, because the air conditioner needs to be started most of the time in the south of hot summer and warm winter indoor in one year, the interior of the outer wall can be kept in a lasting constant-temperature state due to the heat insulation coating, under the condition, the working frequency of the air conditioner is reduced, the power consumption of the air conditioner is relatively low, and the effect of saving electric energy can be achieved.
Furthermore, due to the fact that the alkyd resin is added into the heat insulation coating, the alkyd resin can also reflect heat to sunlight. Similarly, other resin components can be selected, and in order to ensure the reflection of the heat-insulating coating to sunlight, the transparency of the resin is ensured to be higher, the light transmittance is over 80 percent, and the absorption rate of solar energy is low. In order to avoid the heat absorption of the resin, the resin is selected to contain less C-O-C, C-O, O-H groups and the like.
Furthermore, the components show that the heat-insulating coating has good waterproof and anti-seepage effects on the outer wall coated with fine cracks. After the heat-insulating coating is coated on the surface of the outer wall, the outer wall is smooth and flat, and has good hydrophobicity and self-cleaning performance. In addition, the heat-insulating coating has multiple colors, and heat-insulating coatings with different colors can be coated according to different color requirements. In order to ensure the heat insulation and reflection effects of the heat insulation coating, the absorption of visible light and near infrared light by the pigment is smaller and better, and the sunlight scattering caused by sunlight penetrating through the pigment is reduced as much as possible. Therefore, the heat-insulating coating prepared in the application has the performances of efficient cooling, thin layer, decoration, self-cleaning, water resistance, moisture resistance, ultraviolet aging resistance, acid and alkali resistance, corrosion resistance and the like.
Furthermore, the heat-insulating coating has the advantages and effects, so that the heat-insulating coating is not only coated on building exterior walls for use, but also can be applied to cooling in the industries of chemical industry, petroleum, electric power, metallurgy, ships, light textiles, storage, transportation, aerospace and the like, energy is saved, and comfortable human life and working environments are created.

Wherein the insulation temperature difference under strong light is obtained by the following steps: placing a temperature measuring instrument in a closed space with the length of 1 square meter, coating heat insulation paint outside the closed space, placing the closed space under strong sunlight irradiation, collecting a large number of temperature values of three days in the closed space, and obtaining an average value of the temperature values; and comparing the obtained average value with the outdoor temperature to obtain a difference value, thereby obtaining the heat insulation temperature difference under the strong light.
The heat insulation temperature difference under night/cloudy day is obtained by the following steps: the method comprises the steps of placing a temperature measuring instrument in a closed space with the length of 1 square meter, coating heat insulation paint outside the closed space, placing the closed space in an environment at night or in a cloudy day, collecting temperature values of three days in the closed space in a large amount, and obtaining the average value of the temperature values. And comparing the obtained average value with the outdoor temperature, and making a difference value so as to obtain the heat insulation temperature difference at night or on cloudy days.
The light reflectance is obtained by measuring the coated heat-insulating coating by using an automatic visible light rate measuring instrument.
TABLE 1
As can be seen from table 1, when the reflective agent is polyhedral particles with a hollow structure, the reflective effect of the thermal insulation coating is good; when the wall thickness of the particles selected by the reflecting agent is smaller, the heat insulation effect of the heat insulation coating is better; when the particle size of the selected particles of the reflecting agent is smaller, the heat insulation and light reflection performance of the heat insulation coating is better; when different materials are selected as the light reflecting agent, the heat insulation performance of the heat insulation coating is not changed greatly.
