Problems solved by technology

[0008] The main technical problem to be solved by the present invention is that it usually takes a long time to dry after the oil paint is used to complete the work. During this process, due to the electrostatic effect on the screen, some dust or fine hairs are usually absorbed, and are affected by the oiliness of the screen. The long-term infiltration and storage of the surface reduces the quality of oil paintings, and provides a preparation method for quick-drying dust-proof oil paints

[0032] Put 30g of aluminum hydroxide into a three-necked flask filled with 80mL of potassium hydroxide solution with a mass fraction of 40%, heat it up to 110°C, keep it warm until the aluminum hydroxide is completely dissolved, and after cooling down to room temperature, add 40g of it to the three-necked flask White carbon black was stirred and mixed for 2 hours at a speed of 400r / min to obtain a mixed gel of zeolite; in parts by weight, 70 parts of acrylamide, 5 parts of N, N-dimethyl polyacrylamide, 1.0 part of persulfuric acid Ammonium was sequentially added to 90 parts of zeolite mixed gel, and the reaction was continued for 2 hours to obtain the final mixed gel. The final mixed gel was transferred to a reaction kettle with a polytetrafluoroethylene liner, sealed and left at the set temperature. In an oven at 160°C, crystallize for 24 hours, cool to room temperature naturally, take out the reaction product and filter to separate to obtain modified zeolite powder; in parts ...

Abstract

The invention discloses a preparation method of a quick-drying dust-proof oil paint pigment, and belongs to the technical field of oil paint pigment preparation. A double-electric-layer structure is formed in modified zeolite powder in the air drying process, and the adsorption capacity of the modified zeolite powder for the resin is enhanced due to existence of the double-electric-layer structure. A pre-mixed solution is used as a mixed monomer of acrylic resin and then is doped with additives, and a composite resin emulsion is obtained by grafting reaction; after the oil paint pigment is aired, hydrophobic substances in the resin emulsion micelle can be aggregated and arranged on the surface of oil paint; essential oil can be slowly released from diatomite after being absorbed by diatomite, emulsification of the oil paint is promoted, hydrophobicity of the essential oil also contributes to volatilization of water in the oil paint pigment, wettability of the oil paint can be improvedby added bovine bile, fluidity of the pigment is enhanced, surface tension of water is reduced, water is prevented from gathering into water droplets, so that surface drying time of the oil paint pigment is shorted during air drying, the purpose of quick drying is achieved, and the application prospect is broad.

Description

technical field [0001] The invention discloses a preparation method of a quick-drying anti-dust-absorbing oil paint, which belongs to the technical field of oil paint preparation. Background technique [0002] Oil paint is a special painting paint for oil painting, which is made by mixing and grinding pigment powder with oil and glue. The various performances of oil paints can be properly adjusted according to different needs by using different media and auxiliary materials. Most of the products sold in the market are packed in tubes, but they can also be made by yourself. The basic components of oil paints are the same as other paints, which are composed of pigments, body pigments, vehicles and some auxiliary materials such as plasticizers, stabilizers, slow-drying agents or driers. Most of the pigment powders used by the ancient masters come from earth and minerals. [0003] At present, the pigments mainly include watercolor pigments, gouache pigments, oil paints, acryl...
