Description
Technical Field
The invention belongs to the technical field of super-amphiphobic materials, and particularly relates to a super-amphiphobic coating material for a catalyst, and a preparation method and application thereof.
Background
Super-amphiphobic (also called as omniphobic) materials have the advantages of antifouling, antifogging, low adhesiveness, self-cleaning and the like, so that a great deal of demand exists in numerous fields of daily life and industrial production. However, the super-amphiphobic material is still in the research and development stage at present, the actual industrial product is rare, and even the coating product which is claimed to be capable of being subjected to 'omniphobic' on the market at present is difficult to popularize due to the problems of unstable super-amphiphobic performance and short service life. In view of this, more and more research is being devoted to the development of super-amphiphobic materials.
If the mechanical property of the super-amphiphobic coating coated on the surface of the catalyst is insufficient or unstable, the pollution on the surface of the catalyst and the inactivation of the catalyst cannot be avoided, and the inactivation of the catalyst can be accelerated; even when the coating comes off, the reaction system is mixed, which brings about more adverse effects.
Studies have shown that two essential factors in the construction of solid surfaces with super-amphiphobic properties are low surface energy and a rough microstructure, especially a rough microstructure that plays a key role in the oleophobic properties. Inorganic fine particles such as nano silica, nano titania, and carbon nanotubes have been favored by researchers because of their microscopic size, which is suitable for constructing a surface roughness structure. However, the nanoparticles have fatal defects, namely easy agglomeration, which causes the distribution quantity of the nanoparticles in the organic amphiphobic material to be limited, and once the concentration of the nanoparticles is too high, self-agglomeration is formed and the nanoparticles cannot be uniformly distributed in the organic material; moreover, the agglomerated nanoparticles are easy to be compatible with organic materials, so that the inner part of the super-amphiphobic material is layered, and the mechanical property and the stability of the coating material are seriously influenced.
Therefore, chinese patent document CN105820605A discloses a method for preparing a super-amphiphobic nano coating based on flower-like titanium dioxide nano particles, which comprises preparing flower-like titanium dioxide nano particles, modifying the flower-like titanium dioxide nano particles with low surface energy to obtain super-amphiphobic powder, and then directly coating the super-amphiphobic powder on a solid surface needing to obtain super-amphiphobic performance by gluing. Although the technology stated that the inorganic powder can be distributed on the surface of the coating in a concentration of almost one hundred percent, in the actual use process of the coating, the flower-like nano titanium dioxide is extremely easy to be lost, and the super-amphiphobic performance of the coating can be maintained only by continuously supplementing the powder, namely, the super-amphiphobic coating prepared by the technology still has the problems of poor stability and short service life. Therefore, how to overcome the defect that the content of inorganic particles in the existing super-amphiphobic nano coating is too small or is extremely easy to lose is a problem which needs to be solved in the field.
In the field of catalysts, it is known that hydrogenation catalysts are prone to generate carbon deposits (also called coking) during operation, and when the carbon deposits cover the active centers of the catalysts, the catalysts are deactivated, and then the catalysts must be regenerated to recover the activity, which inevitably reduces the catalytic efficiency and increases the energy consumption of production. If the catalyst has a super-amphiphobic surface, the carbon deposition rate can be slowed down, and the service life of the catalyst is prolonged. However, reports about super-amphiphobic catalysts do not appear at present.
Disclosure of Invention
The invention aims to overcome the defect that the service life is too short due to too little inorganic particle content or extremely easy loss in the existing super-amphiphobic nano coating, and further provides a preparation method and application of a super-amphiphobic coating which has uniform inorganic particle distribution, high content and durable performance and can be used for the surface of a catalyst.
Therefore, the technical scheme adopted by the invention for realizing the purpose is as follows:
a preparation method of a super-amphiphobic coating material comprises the following steps:
s1, providing a substrate, coating the substrate with the coating body material, and curing to obtain a coating body;
s2, heating the inorganic nano-particles to T1Dispersing the inorganic nano particles on the surface of the coating body, heating the coating body until the temperature of the inorganic nano particles is consistent with that of the coating body, keeping the temperature for 5-10 min until the coating body reaches a viscous state, cooling and curing to obtain a coating precursor;
the volume ratio of the inorganic nano particles to the coating body is 0.02-0.05: 1;
the T is1The temperature is 0.5-2 ℃ higher than the viscosity fluidization temperature of the coating body material;
s3, repeating the operation of the step S2 for 20-100 times on the coating precursor to obtain the super-amphiphobic coating material.
The thickness of the coating body is 60-500 μm.
And mixing the coating body material and a fluorosilane coupling agent according to a mass ratio of 1: 0.1-0.15, and coating the mixture on the substrate.
The coating body is made of one or more of silica gel, polytetrafluoroethylene, polyvinylidene fluoride, fluorinated polyurethane and fluorine modified polystyrene.
The coating body is made of a mixture of polytetrafluoroethylene and polyvinylidene fluoride in a mass ratio of 1: 1; or the coating body material is fluorine modified polystyrene.
The inorganic nano particles are one or more of nano aluminum oxide, nano silicon dioxide and nano titanium dioxide.
In step S2, ultrasonic treatment is also applied while the coating body is in a viscous state.
The super-amphiphobic coating material prepared by the preparation method.
The application of the super-amphiphobic coating material in the preparation of a catalyst.
One of the applications is to wrap a layer of the super-amphiphobic coating material in a viscous flow state on the surface of the catalyst, and then cool the catalyst under ultrasonic operation to obtain the super-amphiphobic catalyst.
The technical scheme provided by the invention has the following advantages:
1. the super-amphiphobic coating provided by the invention contains uniformly distributed inorganic nanoparticles accounting for 0.5-0.83 of the volume of the coating, and the higher content of the inorganic nanoparticles enables the surface of the coating to have stronger roughness; meanwhile, the fluorosilane coupling agent contained in the coating body can reduce the surface energy of the inorganic nano particles; the prepared coating shows good super-amphiphobic performance due to the lower surface energy and the stronger roughness, the inorganic nanoparticles and the coating body are uniformly distributed, the structure is stable, the loss is not easy to occur, and the super-amphiphobic coating is coated on the surface of the catalyst, so that the inactivation and the surface pollution of the catalyst can be effectively avoided.
2. According to the preparation method of the super-amphiphobic coating, the low-concentration particle spraying is carried out for multiple times, so that the agglomeration phenomenon of inorganic nano particles in the spraying process is ensured, and all nano particles are in a good dispersion state when being sprayed onto the coating body. Through heating to the glutinous fluidization temperature of coating body to the nanoparticle for it is "inlaying" promptly when contacting the coating body, on being fixed in the coating body, then through cooling off earlier and heat and ultrasonic treatment to the coating is whole again, makes the nanoparticle get into the coating body under the relative position that keeps dispersed state, the phenomenon of reunion does not appear. Similarly, the steps are repeated for a plurality of times, so that the relative position of the nano particles can not be changed when the nano particles contact the coating body, and the nano particles only push downwards layer by layer, thereby avoiding the agglomeration of the nano particles. When the catalyst surface is coated, the operation of cooling while ultrasound is carried out enables air in catalyst pores to escape from the catalyst pores through the surface of the coating in the curing process, so that pore channels are formed on the surface, and the contact between the catalyst and reactants is facilitated.
