Problems solved by technology

The paint film formed by this paint is dark brown. Because of the thicker paint film formed by multiple brushing, the surface of the object to be painted turns black due to the reflection of light. This is not black in the essential sense, and the coating is thicker. , increased cost, longer painting period and lower efficiency

Embodiment 1

[0027] Embodiment 1: a kind of preparation method of high-gloss black raw lacquer paint, 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 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.

Embodiment 2

[0028] Embodiment 2: A kind of preparation method of high-gloss black raw lacquer coating, the natural raw lacquer produced in Lichuan City, Hubei Province that is 22% of the filtered 970 water content is put into a ceramic reactor, 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, cool down 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 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 for 2 Hours, standing for 3 days is the high-gloss black raw lacquer coating for autumn and winter.

Embodiment 3

[0029] Embodiment 3: a kind of preparation method of high-gloss black raw lacquer coating, the natural raw lacquer produced in Vietnam that is 35% is dropped in the ceramic reactor with the filtered 990 water content, adds 10 grams of molybdenum hydroxide, 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. It is black material.

Abstract

The invention belongs to the coating chemical modification processing field, and particularly relates to a highlight black raw lacquer coating. The invention aims to provide the high-quality light transparent highlight black raw lacquer coating through improvement of deficiencies of a conventional raw lacquer coating. The highlight black raw lacquer coating is characterized in that the coating material contains a black material, a filtered natural raw lacquer, a wetting agent S-80 and concentrated animal bitter bile; and the prepared highlight black raw lacquer coating is pure in hue and strong in covering power, the times of coating and brushing can be decreased and the thickness of a coating layer is decreased, so that the use cost is reduced and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a preparation method of a high-gloss black raw lacquer paint, in particular to a preparation method of a civil high-gloss black raw lacquer paint. Background technique [0002] Chinese raw lacquer is an excellent natural lacquer produced in my country. my country's raw lacquer production ranks first in the world. It has always been a traditional export product, and currently it is mainly exported to Japan and Southeast Asian countries. Raw lacquer (Rawlaequer) refers to the milky milky liquid flowing out from the phloem cut of sumac (Rhusverniciflua Stokes). The main components include urushiol (60-70%), colloid (5-7%), water-insoluble glycoprotein (1%), laccase (0.24%), water (20-25%) and the like. When it is exposed to air, its color will change from light to dark due to oxidation, and gradually turn into dark brown, and finally become a hard paint film. Raw lacquer film is hard and bright, wear-resistant, heat-resistant a...
