Abstract
The invention discloses a double-coating water-based ceramic paint and application thereof. The ceramic paint comprises an inorganic primer and a water-based finish paint, wherein the inorganic primer is coated on a substrate when in use, and the water-based finish paint is coated after the surface is dried. After the double-coating water-based ceramic paint is dried to form a film, the paint film has strong adhesive force, high heat resistance, wear resistance and hardness, strong cold-hot circulation tolerance and high glossiness of the film layer. The double-coating water-based ceramic paint can be used for surface painting of iron materials or aluminum material substrates, including surface painting of high-temperature-resistant and wear-resistant materials such as hair straighteners, hair curlers, electric irons, inner containers of pots, electric ovens, non-stick pots, exhaust pipes or aluminum plates, and paint films formed by drying the paint can effectively protect the surfaces of the high-temperature-resistant and wear-resistant materials.
Description
Technical Field
The invention relates to the technical field of coatings, in particular to a double-coating water-based ceramic paint and application thereof.
Background
The paint coating is visible everywhere in daily life, and the application thereof is deep into the life and production of people. Paint coatings are chemical mixture coatings that can be applied firmly to the surface of objects for protection, decoration, signage and other special purposes. Particularly, in daily life of people, the high-temperature resistant working surfaces of household appliances such as an electric cooker inner container, a hair curler, an induction cooker and the like are coated with paint coatings, so that the decoration effect is improved, and the protection effect is achieved.
In the process of using the household appliances, scratching is inevitable, so that high requirements are put on the hardness and the wear resistance of the paint coating film on the surface of the household appliances. Otherwise, scratches or paint falling easily occur after scraping, so that the appearance is influenced, the aging of the electric appliance is easily accelerated, and the service life of the electric appliance is shortened.
In addition, these household appliances need to work under high temperature conditions, and not only the paint coating film on the surface of the household appliances needs to have high hardness and wear resistance, but also the household appliances need to have good high temperature resistance. For example, when the inner container of the electric cooker is used, the temperature is usually as high as several hundred degrees, and the paint film layer on the surface of the inner container of the electric cooker falls off if the inner container of the electric cooker is not high-temperature resistant, so that the health of a human body is seriously influenced; when the hair curler is used, if the paint film layer on the surface of the hair curler is not high-temperature resistant and falls off, the paint is dyed on the hair of a user, and the using effect is seriously influenced.
However, due to technical defects, the surface paints used in these existing household appliances are still inferior, and the formed surface paint film layer has poor adhesion and is easy to peel off, or has low hardness and wear resistance and is easy to scratch and scratch. Moreover, under the high-temperature working condition, the danger of color change and even roasting off can occur, and the capacity of resisting cold and hot alternation is insufficient.
With the large scale development of the household appliance manufacturing industry, the requirement for the competitiveness of the core technology is gradually increased. Therefore, the technical requirements for the surface paint coating film layer of these household appliances will be higher and higher.
Disclosure of Invention
The invention aims to provide a double-coating water-based ceramic paint. After the double-coating water-based ceramic paint is dried to form a film, the paint film has strong adhesive force, high heat resistance, wear resistance and hardness, strong cold-hot circulation tolerance and high glossiness of the film layer.
The invention also aims to provide application of the double-coating water-based ceramic paint. The double-coating water-based ceramic paint can be used for surface painting of iron materials or aluminum material substrates, including surface painting of high-temperature-resistant and wear-resistant materials such as hair straighteners, hair curlers, electric irons, inner containers of pots, electric ovens, non-stick pots, exhaust pipes or aluminum plates, and paint films formed by drying the paint can effectively protect the surfaces of the high-temperature-resistant and wear-resistant materials.
The purpose of the invention is realized by the following technical scheme.
A double-coating water-based ceramic paint comprises an inorganic primer and a water-based finish;
the inorganic primer comprises the following components in percentage by weight:
