The heat insulation coating can be used as external heat insulation materials of various high-temperature parts due to high temperature resistance, good heat insulation effect and simple construction process, and has the effects of reducing equipment energy consumption and avoiding damage to other equipment and operators caused by high temperature.
The conventional heat insulation coating comprises two categories of high-temperature-resistant inorganic coating and organic silicon high-temperature-resistant heat insulation coating, the inorganic coating has high temperature resistance and low cost, and the organic heat insulation coating is easy to form a film and is convenient to modify so as to have multiple functions. At present, the technical research of the thermal insulation coating mainly focuses on improving the thermal insulation performance, the adhesion and the like of the coating, the research on the surface characteristics of the prepared coating is rare, and the thermal insulation coating is in contact with the severe environment with high humidity and more oil stains in the actual use process, so that the thermal insulation effect of the coating is easily influenced, the thermal insulation effect is reduced and even loses efficacy, and therefore the surface characteristics of the thermal insulation coating need to be improved to avoid the influence of water, oil and the like on the coating performance.

The water-proof and oil-proof agent provided by the invention has good water-proof and oil-proof effects, is environment-friendly, and can better play the contribution of fluorine-containing substances to the water-proof and oil-proof effects and reduce the influence of a surfactant on the water-proof and oil-proof properties compared with products in the prior art. Chinese patent CN103601891A discloses 1 water-dispersible crosslinkable fluorosilicone resin, a preparation method thereof and application thereof in super-amphiphobic materials. The fluorine-containing polymer and the hydrophilic substance are grafted on the silicon-containing epoxy resin by a chemical grafting method, and meanwhile, part of epoxy groups are reserved. In the method, the epoxy component, the fluorine-containing component and the hydrophilic substance can be flexibly adjusted according to the requirements.

Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a heat-insulating coating with amphiphobic characteristics and a preparation method thereof.
The technical solution of the invention is as follows: the heat insulation coating comprises a heat insulation resin system and a double-hydrophobic heat insulation filler, wherein the addition amount of the double-hydrophobic heat insulation filler is 10-30% of the mass of resin in the resin system;
the amphiphobic heat-insulating filler is formed by grafting hollow microspheres with amphiphobic characteristic groups on the surfaces, wherein the amphiphobic characteristic groups are obtained by grafting reaction of the hollow microspheres and gasified fluorine-containing silane in a floating state.
The mass ratio of the hollow microspheres to the fluorine-containing silane is less than or equal to 100: 8; preferably 100: (10-15), the surface amphiphobic effect is not greatly influenced but is best in comprehensive performance by changing within an optimal range. If the addition amount of the fluorine-containing silane is lower than the range, the surface amphiphobic effect is insufficient, the contact angle to water and oil is small, and the purpose of amphiphobic is not achieved; if the addition amount of the fluorine-containing silane is high, the surface amphiphobic effect is not greatly improved, raw materials are wasted, and the economical efficiency of the heat-insulating coating is poor.
The hollow microspheres comprise one or a mixture of any more of aluminum silicate hollow microspheres, borate hollow microspheres, glass hollow microspheres, alumina hollow microspheres, silicon dioxide hollow microspheres, ceramic hollow microspheres, zirconia hollow microspheres, fly ash floating beads and the like. But not limited to this, as long as the hollow microsphere can satisfy the temperature resistant grade required by use and satisfy the dimensional type at the gasification temperature of the fluorine-containing silane, the gasification temperature of the existing fluorine-containing silane is generally lower than 200 ℃, and if the hollow microsphere is used in the heat insulation coating, the hollow microsphere is generally required to resist the temperature of more than 300 ℃.
The fluorine-containing silane used in the invention can be selected from mono-fluoro, a few fluoro or perfluoro alkane silane, and the like, including but not limited to common tridecafluorooctyl triethoxysilane, heptadecafluorodecyl triethoxysilane, 1H, 2H, 2H-perfluorodecyl triethoxysilane, and the like.
The hollow microspheres are used for the heat-insulating coating, preferably subjected to high-temperature activation treatment, preferably subjected to high-temperature treatment at 300-400 ℃ for 4-5 hours, the specific temperature is determined according to the types of the hollow microspheres, and the high-temperature treatment temperature cannot be higher than the dimensional temperature of the hollow microspheres.
The invention has no special limitation on the type of the heat insulation resin system (comprising a resin matrix, a diluent, a curing agent and the like) in the heat insulation coating, and the heat insulation coating can be two-component or single-component and can be cured at room temperature or by heating. Any resin system can be used as long as it can be used as a heat insulating coating, and the specific temperature resistance of the obtained heat insulating coating depends on which resin system is used, such as various room temperature vulcanizable silicone rubbers or silicone-nitrogen rubbers, epoxy resins, chlorosulfonated polyethylene, phenol formaldehyde, epoxy-polyurethane, polysulfide-epoxy, etc., which are used in a commonly used room temperature vulcanized silicone rubber system and have a use temperature in the range of 600 ℃. The type and content of the curing agent used in the resin system are determined according to the type and quality of the adopted resin matrix, the proportion of the resin matrix and the curing agent in the preparation process is a known technology in the field, and the specific proportion can be adjusted according to actual requirements.
According to the invention, the amphiphobic heat-insulating filler with amphiphobic property is added into the heat-insulating coating, so that the coating of the heat-insulating coating after film formation has excellent hydrophobic and oleophobic properties. The addition amount of the amphiphobic heat-insulating filler is 10-30% of the mass of the resin. Within the above-mentioned range, the larger the amount of the amphiphobic heat-insulating filler is, the better the heat-insulating effect is, and the less the influence on the amphiphobic property is. If the proportion of the amphiphobic heat-insulating filler is too low, the heat conductivity of the cured heat-insulating coating is higher, so that the heat-insulating effect is poor, and the amphiphobic performance of the coating is influenced to a certain extent; if the proportion of the amphiphobic heat-insulating filler is too high, the coating has poor film forming property and weak adhesive force with a matrix, and the long-term use effect of the heat-insulating coating is influenced.
A preparation method of a thermal insulation coating is realized by the following steps:

a1.1, activating the surface of the hollow microsphere,
treating the hollow microspheres at a high temperature of 300-400 ℃ for 4-5 h;
the invention adopts high temperature to carry out surface activation treatment on the hollow microspheres, thereby facilitating the subsequent reaction with gasified fluorine-containing silane.

a1.1.1, removing the water vapor adsorbed on the surface of the hollow microsphere;

The temperature of the hollow microsphere surface activation treatment is 300-400 ℃, if the treatment temperature is too low, the activation effect is insufficient, and the subsequent surface double-hydrophobic effect is influenced; if the treatment temperature is too high, the particles tend to sinter, the dispersing effect is poor, and the surface amphiphobic effect is also negatively affected. Within the required treatment temperature and time range, the subsequent surface amphiphobic effect is not greatly influenced.
A1.2, enabling the hollow microspheres subjected to surface activation treatment in the step A1.1 to be in a suspension state, and reacting with gasified fluorine-containing silane for not less than 2 hours to obtain the amphiphobic heat-insulating filler;
the reaction time ensures that the grafting reaction is sufficient, and as many amphiphobic groups as possible are grafted, so that the reaction time cannot be less than 2 hours generally.
The step can be carried out by adopting a boiling dryer, but the equipment is not limited as long as the hollow microspheres are enabled to be in a suspension state to react with the gasified fluorine-containing silane. Suspending the hollow microspheres subjected to surface activation treatment by using airflow of a boiling dryer so as to ensure that the hollow microsphere particles are in full contact with a silane reagent; meanwhile, the boiling dryer gasifies the fluorine-containing silane by heating, increases the contact area with the hollow microsphere particles while improving the reaction activity, enables the double-hydrophobic groups grafted on the surfaces of the hollow microspheres to be high-temperature resistant, cannot fall off easily if contacting high temperature like the liquid-phase grafted hydrophobic and oleophobic groups, and is suitable for being used in a heat-insulating coating.
The second step, preparing the heat-insulating coating,
and adding the amphiphobic heat-insulating filler prepared in the first step into a heat-insulating resin system to obtain the heat-insulating coating.
The adding amount of the double-hydrophobic heat-insulating filler is 10-30% of the mass of the resin.
When the heat insulation coating is prepared in the step, a diluent and/or a curing agent can be added according to specific situations, and the method is well known in the art.
The thermal insulation coating is obtained by spraying the thermal insulation coating, the specific process parameters are known in the art, and the person skilled in the art selects the appropriate parameters according to the actual situation.
The invention is based on reasonable material composition design, and various materials are matched with each other through a smart processing mode, so that a good surface double-hydrophobic heat-insulation coating effect is achieved. The heat insulation resin system has excellent adhesion effect and can also achieve the effect of bearing heat insulation filler; the hollow microspheres treated by the fluorine-containing silane are added, so that the hydrophobic and oleophobic effects on the surface of the coating are improved while the heat insulation effect is achieved, the prepared heat insulation coating has the surface double-hydrophobic self-cleaning characteristic, and the maintainability and the practicability of the heat insulation coating are improved.
Compared with the prior art, the invention has the beneficial effects that:
