Environment-friendly coating for surface maintenance of wooden handicrafts, and preparation method of environment-friendly coating

Abstract

The invention discloses an environment-friendly coating for surface maintenance of wooden handicrafts, and a preparation method of the environment-friendly coating. The environment-friendly coating isprepared from the following components: natural vegetable oil, an antifouling agent, a highly reductive plant extract, a water-based fungicide, a permeable agent, a cross-linking agent and an antioxidant. The environment-friendly coating is harmless to human body health and has a good protective effect on the handicrafts; two cutting edges are mounted at the outer edges of stirring blades in an efficient mixer for mixing environment-friendly coating raw materials, so that the efficient mixer is good in mixing effect and high in mixing efficiency; by arranging a foam plate, a first elastic plate, a second elastic plate and a rubber pad, a certain cushioning effect is achieved so that vibration generated when a servo motor operates can be reduced; by connecting coil springs to telescopic rods in a sleeving mode, vibration of a mixing tank can be reduced, thus the vibration reduction effect of the efficient mixer is good, and noise generation is reduced; and through contraction of an aircylinder, a baffle gets away from the side wall of the mixing tank, thus automatic discharging is achieved, and the discharging process is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of handicraft maintenance, in particular to an environmentally friendly coating for surface maintenance of wooden handicrafts and a preparation method thereof. Background technique [0002] Wood is one of the main natural materials for industry, agriculture, national defense, and civil use today. It has many advantages such as easy processing, natural beautiful patterns, luster, and color, and is widely used in furniture and other occasions. However, due to water, bacteria, lignin, etc., natural wood will slowly rot and change color after processing, swell and shrink when wet, and then deform and crack. formaldehyde content, and the existing wood protective coatings mainly rely on chemical synthetic resins to form films, which contain a large amount of benzene, alcohol, and ketone organic solvents, which seriously pollute the indoor air after volatilization and affect people's health; In the process of stor...

Problems solved by technology

[0004] In order to overcome above-mentioned technical problem, the object of the present invention is to provide a kind of wooden handicraft surface maintenance environmental protection coating and preparation method thereof: (1) this environmental protection coating is main raw material with natural vegetable oil, does not contain volatile solvent, It will not pollute the indoor air, and the plant extract contains a large number of natural reducing components, which can decompose the volatile harmful substances contained in the wood, and solve the problem of a large number of benzenes, alcohols, and ketones in the wood itself and existing coatings. Organic solvents, after volatilization, seriously pollute the indoor air and affect people's health; the addition of antifouling agents can make wooden handicrafts have remarkable stain resistance, effectively reduce the number of wiping times, and effectively prolong the life of wooden handicrafts. The service life solves the problem that wooden handicrafts are easily covered with ash layer during storage, and some ash layers are even difficult to remove; water-based fungicide FF-2 antiseptic fungicide is a broad-spectrum high-efficiency and low-toxicity industrial antiseptic sterilization Antioxidants can effectively eliminate various microorganisms. Antioxidants can inhibit the oxidation of the surface of wooden handicrafts. It solves the problem that natural wood will slowly rot and discolor after processing due to water, bacteria, lignin, etc., swelling and shrinking when wet, and then deformed and cracked , At the same time, bacteria and mold erosion lead to the problem of wood mold and rot; (2) The distance between the mixing blade and the inner wall of the mixing tank is successively reduced, so that the raw materials of the environmental protection paint can be mixed evenly, and the outer edge of the mixing blade is equipped with two cutting blades, which will Environmentally friendly paint raw materials are cut, which solves the problems of insufficient uniformity of raw materials mixed by existing high-speed mixers, lumps appear in raw materials, poor mixing effect, and low mixing efficiency; (3) by setting foam boards, the first The elastic plate, the second elastic plate, and the rubber pad play a certain buffering effect, so that the vibration generated when the servo motor is running can be reduced. A coil spring is sleeved on the telescopic rod, so that the rotation of the rotating shaft drives the vibration generated by the mixing tank. Spring absorption reduces the vibration of the mixing tank, which solves the problem that the entire equipment is in a vibrating state when the existing high-speed mixer is working and generates a lot of noise; Sealing, the shrinking of the cylinder makes the baffle leave the side wall of the mixing tank, and the uniformly mixed raw materials are discharged from the discharge pipe, which solves the problem that the existing high-speed mixer needs to manually open the discharge port valve after the raw materials are mixed. cumbersome questions
