Problems solved by technology

The former method has huge equipment, takes a long time, and the output is small, and the product is dehydrated, which is uneconomical. The appearance of the product changes completely, the color changes from milky white to brown or black, and the viscosity increases, which is not conducive to construction; the coating prepared by the latter method It belongs to the category of synthetic coatings. The high price of the product makes it difficult to compete with synthetic coatings that use fossil resources as raw materials. Moreover, the product contains volatile organic compounds and consumes a large amount of organic solvents during the preparation process, which is harmful to the human body and pollutes the environment.
Therefore, these two methods are neither economical nor environmentally friendly, and neither can fundamentally solve the problem of quick-drying and popularization of raw lacquer

Embodiment 1

[0011] Embodiment 1: at room temperature, 1g nano-TiO 2 Add 20ml of dimethyl sulfoxide to the three-necked flask, mechanically stir for 30min to make it evenly dispersed, and then add nano-TiO 2 10% urushiol by mass, continue to stir for 4 hours to make it fully react. The reacted mixture was centrifuged at high speed, washed and dried. The obtained urushiol-modified nano-TiO 2 In water containing 5% (v / v) n-butanol added at a mass ratio of 5%, stirring and ultrasonication for 30 min each, repeated twice, to obtain uniformly dispersed modified nano-TiO 2 Powder suspension.

[0012] The prepared urushiol-modified nano-TiO 2 The suspension was added to the raw lacquer emulsion at a mass ratio of 1%, stirred for 20 minutes, and then homogenized with a homogenizer for 40 minutes to obtain urushiol-modified nano-TiO 2 Hybrid lacquer coatings.

Embodiment 2

[0013] Embodiment 2: Nano-TiO 2 The water containing 8% (v / v) ethanol added by mass ratio 5%, stirred for 30min, ultrasonicated for 30min, repeated 2 times, and prepared uniformly dispersed nano-TiO 2 Powder suspension.

[0014] The prepared nano-TiO 2 The suspension was added to the raw lacquer emulsion at a mass ratio of 5%, stirred for 20 minutes, and then homogenized with a homogenizer for 1.5 hours to obtain nano-TiO 2 Hybrid lacquer coatings.

Embodiment 3

[0015] Example 3: Ca 2+ - The rectorite is uniformly dispersed in water, and after high-speed stirring, a stable rectorite suspension is obtained. Prepare a certain amount of sodium dodecylsulfonate as a 1% aqueous solution, add it dropwise to the rectorite suspension at 70°C, stir for 5 hours, filter with suction, wash, and dry to obtain sodium dodecylsulfonate modified rectorite. Topstone. Sodium dodecylsulfonate modified rectorite was added into water containing 10% ethanol (v / v) according to the mass ratio, stirred for 30 minutes, ultrasonicated for 20 minutes, and repeated twice to obtain evenly dispersed dodecyl Sodium alkylsulfonates modify rectorite suspensions.

[0016] Add the prepared sodium dodecylsulfonate modified rectorite suspension into the raw lacquer emulsion at a mass ratio of 1%, stir for 20 minutes, and then use a ball mill to grind for 1 hour to obtain sodium dodecylsulfonate modified rectorite Stone hybrid raw lacquer coating.

Abstract

The invention relates to a green quick drying hybrid raw lacquer and a preparation method thereof. The hybrid raw lacquer is prepared by uniformly mixing natural Rhus verniciflua sap and a small number of inorganic materials such as nano TiO2, rectorite, nano calcium carbonate, nano zinc oxide and the like, and dispersing, wherein the inorganic materials account for 0.005 to 5 mass percent of thehybrid raw lacquer. The prepared hybrid raw lacquer can be quickly dried at room temperature and in a wide relative humidity range, a film has excellent mechanical properties, luster, ultraviolet resistance, antibacterial property and the like, and the hybrid raw lacquer is stable, nontoxic, pollution-free and environment-friendly and can serve as a substitute product of a synthetic coating to beapplied to industry, restoration of cultural relics, and daily life of residents.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a green quick-drying hybrid raw lacquer coating and a preparation method thereof. Background technique [0002] Raw lacquer is the only natural green paint in the world that can be catalyzed by biological enzymes to form a film at room temperature. The main components of raw lacquer include urushiol (60-70%), gum (5-7%), water-insoluble glycoprotein (~1%), sumac enzyme (~0.24%) and water (20-25%), etc. . The paint film of raw lacquer is hard and bright, wear-resistant, heat-resistant, and corrosion-resistant. Unearthed lacquerware can still remain intact after thousands of years, so raw lacquer is known as the "king of paint". Yet, for a long time, shortcomings such as sensitization of raw lacquer, high viscosity, difficult construction, harsh drying conditions, and single color make this natural green paint not popularized and applied. Among them, raw lacquer must be cured and ...
