Abstract

The invention discloses a method for preparing a detergent by using drainage oil, which comprises the preparation of a basic soap stock and burdening of detergent raw material. The preparation of the basic soap stock includes putting a certain amount of drainage oil into a reactor, slowly dropwisely adding a sodium hydroxide solution at a constant temperature of 100 DEG C for saponification reaction, crushing the solidified and precipitated saponification product, drying in an oven, and porphyrizing to get the drainage oil soap stock. The detergent is prepared by burdening the following materials according to a mass ratio: drainage oil soap stock, sodium carbonate, LAS, sodium metasilicate, AEO-9, 4A zeolite, TX-10, sodium citrate, glycerol, alkaline proteases, sodium carboxymethyl cellulose, and sodium sulphate. According to the present invention, the drainage oil is used as the main raw material and matched with a conventional surfactant with excellent performance to obtain the novel efficient and environmental-friendly detergent.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a method for using waste oil for preparing a cleaning agent. Background technique [0002] Waste oil is the waste oil taken from the waste oil trap, which is extracted through simple heating and dehydration, slag removal, neutralization, precipitation and other processes. Its appearance is yellowish brown and has a special odor; the composition of waste oil is complex, Contains various edible oil components, if the oily wastewater is directly discharged into public water bodies, it will cause serious environmental pollution and waste of resources. [0003] At present, domestic and foreign countries are competing to develop the recycling of waste oils. There are also reports about waste oils being used as raw materials for the production of soaps and cosmetics, but they are all researches in the experimental stage. In a word, since waste oil is a new food safety problem in recent years, there ...
