Description

Coating composition of steam generation coating and steam generation coating
Technical Field
The invention belongs to the field of coatings, and particularly relates to a coating composition of a steam generation coating and the steam generation coating.
Background
The iron and garment steamer quickly vaporize to steam by adding water dropwise. If the water drops are directly dropped on the surface of the high-temperature metal, the water drops can be supported by the steam generated at high temperature and quickly sprayed out, and the steam effect can not be achieved. Therefore, the coating layer using a diffusion agent is coated on the metal surface, the coating layer is loose and porous and has excellent adsorptivity at high temperature, and water drops are quickly adsorbed by the coating layer when dropping on the high-temperature coating layer surface, spread out on the coating layer surface, increase the heated area, quickly vaporize into water vapor, and can not generate a water spraying phenomenon.
There are two types of diffusion agent coatings on the market, one is a thermal spray coating and one is a cold spray coating. The thermal spraying method is to spray at a high temperature of about two hundred ℃ to quickly vaporize and expand volatile substances in the coating in the spraying process, and form holes on the surface of the coating, so that a loose and porous structure is generated. However, the structure has the defects that in the thermal spraying process, volatile substances volatilize in a large amount when the paint reaches a base material, the paint loses fluidity, the base material cannot be wetted and spread, the adhesiveness of the paint is greatly reduced, the paint can fall off after long-term use, the problem of powder falling occurs, the service life is short, and the paint is not suitable for being used on products of steamer type which need food contact.
The cold spraying method coating is a nano phenol coating, and a large amount of nano silica sol is added into the water-based phenolic resin to serve as a filler, so that the phenolic resin cannot completely fill gaps among sol particles after the coating is formed into a film due to the existence of the large amount of silica sol, and a loose and porous structure is caused. Obviously, this approach also has a significant disadvantage in terms of adhesion to the filler and adhesion to the substrate, and is more prone to paint and powder fall than thermal spray coatings.
The conventional cooking utensil achieves the steaming effect by boiling water in the food steaming process, and has two problems, namely, the boiling of water needs a certain time and the cooking time is slow; secondly, steam needs to be boiled out by adding excessive water, a part of energy can be absorbed in the heating process of the excessive water, the energy is wasted, and meanwhile, the excessive water needs a larger space and has an influence on the volume of an electric appliance.
Disclosure of Invention
The present invention aims to provide a coating composition for a steam generating coating layer, which can solve at least one of the above problems.
According to one aspect of the present invention, there is provided a coating composition for a vapor generating coating comprising a film former resin comprising one or more of a polyethersulfone resin, a polyetheretherketone resin, a polyphenylene sulfide resin, and a polyamideimide resin; and
an inorganic filler selected from the group consisting of: one or more of silicate, mica, zeolite, sepiolite, vermiculite and hollow glass microbeads; and

According to the coating composition of the steam generation coating, the formed coating has loose porosity and excellent adsorptivity at high temperature, so that water drops drop on the surface of the coating at high temperature, are quickly adsorbed by the coating and spread on the surface of the coating, increase the heating area, quickly vaporize into steam, greatly shorten the vaporizing time of the water drops on the surface of the coating, and achieve the aim of energy conservation.

Therefore, the purpose of assisting film formation can be achieved through the high-boiling point solvent, and the adhesive force of the whole body can be improved.
In some embodiments, a coating composition of a vapor generation coating further comprises a nano-oxide. Therefore, the nano oxide catalyzes water at high temperature to form free radical molecules, and the free radicals can destroy cell walls of microorganisms such as mould, so that the microorganisms are killed, and meanwhile, the free radicals also have a certain inhibition effect on mites, and can play a certain role in killing mites on clothes when being used on an iron.

8-15 parts of polyether sulfone resin, polyether ether ketone resin, polyphenylene sulfide resin or polyamide imide resin, 15-20 parts of high boiling point solvent, 8-10 parts of inorganic filler and 0.5-3 parts of nano oxide. Therefore, the coating is not loosened under the condition of ensuring that the coating is porous; meanwhile, the paint can be ensured to be leveled on the base material, the energy is saved, the adhesive force is ensured, and the corrosion resistance is improved.

30-50 parts of adhesive resin, 1-5 parts of filler, 0.2-20 parts of fluoropolymer resin, 3-5 parts of auxiliary agent, 1-6 parts of surfactant and the balance of deionized water.
In some embodiments, the binder resin includes one or more of polyethersulfone resin, polyetheretherketone resin, polyphenylene sulfide resin, and polyamideimide resin.
In some embodiments, the fluoropolymer resin comprises one or more of polytetrafluoroethylene, perfluoroethylene propylene copolymer, perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene copolymer.

The coating composition of the steam generating coating is mainly used for surface coatings of flatirons, garment steamer and steamer, so that the surface coating is loose and porous, has excellent adsorptivity at high temperature, and water drops drop into the surface of the coating at high temperature, are quickly adsorbed by the coating, are quickly spread on the surface of the coating, increase the heating area, quickly vaporize into steam, and can not generate a water spraying phenomenon.
