Abstract

The invention discloses an air-drying protective paint for plastics and a preparation method thereof. The paint comprises butyl acrylate, light calcium carbonate, talcum powder, bentonite, a defoaming agent, ethylene carbonate, ethyl 2-cyanoacrylate, ethylene glycol monoethyl ether, disodium succinate, N-oleoylsarcosine octadecylamine and ethyl acetate. The preparation method comprises the following steps: adding the butyl acrylate, light calcium carbonate, bentonite, ethylene carbonate and ethyl acetate into a reaction kettle which is provided with a condenser, a stirrer and a thermometer, stirring, heating to reflux, continuing stirring to obtain a mixture 1, adding the ethyl 2-cyanoacrylate, ethylene glycol monoethyl ether and N-oleoylsarcosine octadecylamine, continuing stirring under reflux, cooling to room temperature, finally adding the talcum powder, defoaming agent and disodium succinate, and uniformly mixing. The air-drying protective paint for plastics has the advantages of quick air-drying capacity and weather resistance, and can be widely popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of chemical paint preparation, in particular to a self-drying plastic protective paint and a preparation method thereof. Background technique [0002] At present, coatings are used in many fields, and are widely used in various fields such as machinery, automobiles, electronics, and communications. Since coatings are often exposed to the atmosphere during use and are eroded by oxygen, moisture, etc., it is easy to cause metal corrosion, wood decay, cement weathering and other phenomena. The requirements in all aspects have been improved, especially for the hardness, wear resistance, fullness, impact resistance, aging resistance, corrosion resistance, water resistance, oil resistance, chemical resistance, light resistance, temperature resistance and other properties of coatings. The requirements are getting higher and higher, so it is necessary to study more advanced coatings to meet people's needs. At pres...
