Abstract

The invention relates to a method for preparing plastic toner dispersing oil from swill-cooked dirty oil and application of the dispersing oil in color matching of plastic, wherein the method for preparing the plastic toner dispersing oil comprises the following steps: firstly, centrifuging and precipitating the swill-cooked dirty oil, and removing solids; heating to 110-130 DEG C, and carrying out heat preservation for 0.2-0.5h; adding 4-6% of hydrogen peroxide, cooling to 60-90 DEG C, and stirring for 0.3-0.5h; adding 6-8% of activated clay, holding the temperature, and continuing stirring for 0.3-0.5h; precipitating for 0.5-1h; and finally, filtering and obtaining pure oil and fat capable of being used as the plastic toner dispersing oil. The organic plastic toner dispersing oil prepared from the swill-cooked dirty oil has the advantages of low price, simplicity in operation, obvious effect, environmental friendliness and health. The dispersing oil provided by the invention is not harmful to the environment and human body, and has obvious social benefits. The plastic toner dispersing oil prepared by the method provided by the invention is applied to the color matching of the plastic. Compared with the traditional color matching method, the color is more uniform, the surface is bright and clean, the price is low, the processing is simple, the product yield is increased, and the environmental friendliness and economic benefits are obvious.

Description

technical field [0001] The invention belongs to the field of preparation and application of disperse oil, in particular to a method for preparing disperse oil from waste oil and a method for color matching of plastics. Background technique [0002] Our country needs to process a large amount of plastic products every year. Because of people's requirements for the appearance of products, pigments or dyes are mixed into plastic products. Because most of the pigments or dyes are in powder form (hereinafter referred to as pigments and dyes), they are light in weight and easy to float, resulting in dust pollution during processing, which is not conducive to health and endangers the environment. Moreover, toner is not easy to adhere to the surface of plastic particles, and is not easy to disperse. People often use other means to solve the dispersion problem in the process of plastic color matching. [0003] The mixing of dispersing oil and toner can reduce the chemical and physi...
