Embodiment 1

[0016] At a temperature of 32 degrees Celsius and a humidity of 85%, pour raw lacquer and drying vegetable oil into a mixing tank, stir and disperse for 2 hours at 110 rpm, and then pour in lignin, phenolic compounds, Chlorine salt, graphite powder, polyhydroxy acrylic resin and additives are poured in, and ultrasonic dispersion is used for 50 minutes under stirring.

[0017] In this example, lignin: 19 parts; phenolic compound: 9 parts, the phenolic compound is tannic acid; chlorine salt: 1 part, the chlorine salt is ferric chloride, antimony chloride and chlorinated One of aluminum; graphite powder: 3 parts; dry vegetable oil: 6 parts, the dry vegetable oil is raw tung oil; polyhydroxy acrylic resin: 6 parts, the hydroxyl value in the polyhydroxy acrylic resin is 70- 80㎎KOH / g; raw lacquer: 51 parts, the composition of the raw lacquer includes urushiol, water, nitride and gum, the content of urushiol is greater than 65%; auxiliary agent: 11 parts.

Embodiment 2

[0019] At a temperature of 28 degrees Celsius and a humidity of 75%, pour raw lacquer and drying vegetable oil into a mixing tank, stir and disperse for 1 hour at 90 rpm, and then pour in lignin, phenolic compounds, Chlorine salt, graphite powder, polyhydroxy acrylic resin and additives are poured in, and ultrasonic dispersion is used for 30 minutes under stirring.

[0020] In this example, lignin: 15 parts; phenolic compound: 12 parts, the phenolic compound is tannic acid; chloride salt: 0.8 part, the chloride salt is iron chloride, antimony chloride and chloride One of aluminum; graphite powder: 1 part; dry vegetable oil: 8 parts, the dry vegetable oil is raw tung oil; polyhydroxy acrylic resin: 4 parts, the hydroxyl value in the polyhydroxy acrylic resin is 70- 80㎎KOH / g; raw lacquer: 59 parts, the composition of the raw lacquer includes urushiol, water, nitride and gum, the content of urushiol is greater than 65%; auxiliary agent: 3 parts.

Embodiment 3

[0022] At a temperature of 30 degrees Celsius and a humidity of 80%, pour raw lacquer and drying vegetable oil into a mixing tank, stir and disperse at 100 rpm for 1.5 hours, and then pour in lignin, phenolic compounds, Chlorine salt, graphite powder, polyhydroxy acrylic resin and additives are poured in, and ultrasonic dispersion is used for 40 minutes under stirring.

[0023] In this example, lignin: 17.5 parts; phenolic compound: 10 parts, the phenolic compound is tannic acid; chloride salt: 0.9 part, the chloride salt is iron chloride, antimony chloride and chloride One of aluminum; graphite powder: 2 parts; dry vegetable oil: 7 parts, the dry vegetable oil is raw tung oil; polyhydroxy acrylic resin: 5 parts, the hydroxyl value in the polyhydroxy acrylic resin is 70- 80㎎KOH / g; raw lacquer: 55 parts, the composition of the raw lacquer includes urushiol, water, nitride and gum, the content of urushiol is greater than 65%; auxiliary agent: 9 parts.

Abstract

The invention belongs to the technical field of coatings, and particularly discloses a lignin raw lacquer compound coating. The lignin raw lacquer compound coating is prepared from 15-20 parts of lignin, 8-12 parts of phennolic compound, 0.8-1 part of chlorine salt, 1-3 parts of graphite powder, 6-8 parts of dried vegetable oil, 4-6 parts of polyhydroxy acrylic resin, 50-60 parts of raw lacquer and 3-15 parts of auxiliaries. The lignin raw lacquer compound coating can greatly improve the adhesive force of the raw lacquer, the raw lacquer can become an antistatic coating, the application rangeof the raw lacquer compound coating is expanded, and the mechanical performance of the raw lacquer compound coating like the rigidity, flexibility and the shock resistance is improved; meanwhile, thedrying time is shortened, the function of resisting ultraviolet light is improved, the cost is low, and manufacturing is facilitated.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a lignin raw lacquer composite coating. Background technique [0002] Raw lacquer, commonly known as "earth lacquer", also known as "national lacquer" or "big lacquer", is a milky white pure natural liquid paint harvested from lacquer trees. It gradually turns brown when exposed to air, and the surface dries and hardens in about 4 hours. to form a paint film. The economic value of raw lacquer is very high. It has the characteristics of corrosion resistance, wear resistance, acid resistance, solvent resistance, heat resistance, good water insulation and insulation, and luster. High quality coating for furniture etc. It is also one of the important materials traditionally exported by China, and it is famous in the world for its large quantity and good quality. In view of the defects of raw lacquer performance, it is necessary to modify it, but the existing raw lacquer composite...
