Problems solved by technology

The paint film formed by this paint is dark brown, because it is painted multiple times to form a thicker paint film, which makes the surface of the object to be painted black due to the reflection of light, which is not black in the essential sense, and the coating is thicker , which increases the cost, the painting period is longer, and the efficiency is lower

Embodiment 1

[0028] Embodiment 1: a kind of black raw lacquer paint based on natural raw lacquer, the natural raw lacquer produced in Pingli County, Shaanxi Province, which is 30% through filtering 980 grams of water content is dropped into a ceramic reactor, and 20 grams of hydroxides of molybdenum are added, Turn on the heating, stirring, and air extraction devices, and control the temperature between 110°C and 130°C. When the paint is completely black and the viscosity is 400 seconds, stop heating immediately, cool down to 60°C, and take it out of the kettle while it is hot. For black material. After it is completely cooled, take 489 grams of black material, mix with 489 grams of natural raw lacquer produced in Pingli County, Shaanxi Province with a water content of 30% after filtering, add 2 grams of S-80 wetting agent, 20 grams of concentrated pig gall, and stir 2 hours, standing for 3 days is the high-gloss black raw lacquer coating in spring and summer. Repeat 3 times.

Embodiment 2

[0029] Embodiment 2: A kind of black raw lacquer paint based on natural raw lacquer, the natural raw lacquer produced in Lichuan City, Hubei Province is dropped into a ceramic reactor with filtered 970 water content of 22%, and 30 grams of molybdenum hydroxides are added, and the heating is started. , Stirring, and air extraction device, control the temperature between 110°C and 130°C, when the paint is completely black and the viscosity is 400 seconds, stop heating immediately, lower the temperature to 60°C, take it out of the kettle while it is hot, and it is black material. After it is completely cooled, take 391.2 grams of black material, 586.8 grams of water content is 22% natural raw lacquer produced in Lichuan City, Hubei Province after filtering and mix, add 2 grams of S-80 wetting agent, 20 grams of concentrated ox gall, stir 2 Hours, standing for 3 days is the high-gloss black raw lacquer coating for autumn and winter. Repeat 3 times.

Embodiment 3

[0030] Embodiment 3: a kind of black raw lacquer paint based on natural raw lacquer, the natural raw lacquer produced in Vietnam that is 35% is dropped in the ceramic reactor by the filtered 990 water content, adds 10 grams of hydroxides of molybdenum, starts heating, stirring, The air extraction device controls the temperature between 110°C and 130°C. When the paint is completely black and the viscosity is 400 seconds, stop heating immediately, lower the temperature to 60°C, and take it out of the kettle while it is hot for later use, which is the black material. After it is completely cooled, take 391.2 grams of black material, 586.8 grams of water content is 22% filtered natural raw lacquer mixed in Vietnam, add 2 grams of S-80 wetting agent, 20 grams of concentrated ox gall, stir for 2 hours, and let it stand Place it for 5 days to use high-gloss black lacquer paint in autumn and winter. Repeat 3 times.

Abstract

The present invention relates to a preparation method of a black coating material based on a natural raw lacquer. The preparation method comprises: mixing a natural raw lacquer and a molybdenum hydroxide according to a certain ratio, decocting through a heating method to obtain a black material, and carrying out uniform mixing dispersion on the natural raw lacquer and the black material according to a certain ratio to obtain the black coating material. According to the present invention, during the decocting of the black material, the ratio of the natural raw lacquer to the molybdenum hydroxide is according to the required proper weight ratio, and the weight ratio of the black material to the natural raw lacquer is 30-40%; the prepared black paint coating material can be rapidly dried in the wide temperature and humidity range; the mechanical property, the gloss, the decorative property, the coating performance, the heat resistance and other performances of the paint film are significantly improved; and the obtained coating material is stable, non-toxic, pollution-free and environmentally friendly, can be used as the substitute for synthetic coating materials, can be used in industrial anticorrosion, cultural treasure repair, food containers, and daily life of residents.

Description

technical field [0001] The present invention relates to a black lacquer paint based on natural lacquer. Background technique [0002] Raw lacquer (Raw laequer) refers to the milky white milky liquid that flows out from the phloem cut of sumac (Rhus verniciflua Stokes). The main components include urushiol (60-70%), gum (5-7%), water-insoluble glycoprotein (-1%), urushiol (-0.24%) and water (20-25%), etc. When exposed to the air, its color changes from light to dark due to oxidation, and gradually turns to dark brown, and finally becomes a hard paint film. Raw lacquer paint film is hard and bright, wear-resistant, heat-resistant and corrosion-resistant. It is a kind of natural paint, which has been used in my country for more than 7,000 years. It is called the "ancestor" of paint. It has had an important impact on my country's political, economic, and cultural life. It is a major discovery after the four great inventions. . In order to facilitate use and improve its decora...
