Embodiment 1

[0036] The raw materials of a new type of waste oil curing agent are composed according to the following weight percentages: 89% by mass of 12-hydroxystearic acid, 2% by mass of magnesium silicate monohydrate, 3% by mass of starch, and 3% by mass of ethanol. 6%.

[0037] After mixing the above substances in proportion, stir the mixture evenly with a glass rod, put the mixture into an MMCS-900 ultrasonic cleaner, and vibrate for 5 minutes at a selected frequency of 2.8MHz under normal pressure. Take out the uniformly mixed product, put it into a DZF-6030 desktop vacuum drying oven to dry, set the temperature at 20°C, and the drying time is 2.5h. After the drying is completed, grind it to 20 mesh to obtain the curing agent 12- HSA.

[0038] Take 90ml of sunflower kernel oil, respectively numbered "12-HSA" and "curing agent on the market", heat the oil to 100 ° C, slowly cool to 80 ° C, and the curing agent 12-HSA prepared in this example Take 2.5g and 2.5g of the commercially ...

Embodiment 2

[0042] The raw materials of a new type of waste oil curing agent are composed according to the following weight percentages: 12-hydroxystearic acid mass percentage is 92%, magnesium silicate monohydrate is 2% by mass percentage, starch mass percentage is 1%, ethanol mass percentage is 5%.

[0043] After mixing the above substances in proportion, stir the mixture evenly with a glass rod, put the mixture into an MMCS-900 ultrasonic cleaner, and vibrate for 5 minutes at a selected frequency of 2.8MHz under normal pressure. The homogeneously mixed product was taken out and put into a DZF-6030 desktop vacuum drying oven for drying, the temperature was set at 20°C, and the drying time was 2.5 hours. After drying, it is ground to 20 meshes to obtain the curing agent 12-HSA.

[0044] Take 100ml of sunflower kernel oil, respectively numbered "12-HSA" and "curing agent on the market", heat the oil to 100°C, slowly cool to 85°C, and take 2.7g of the curing agent prepared in this example...

Embodiment 3

[0046] The raw materials of a novel waste oil curing agent are composed according to the following weight percentages: 12-hydroxystearic acid mass percentage is 85%, magnesium silicate monohydrate is 6% by mass percentage, starch mass percentage is 5%, ethanol mass percentage is 4%.

[0047] After mixing the above substances in proportion, stir the mixture evenly with a glass rod, put the mixture into an MMCS-900 ultrasonic cleaner, and vibrate for 5 minutes at a selected frequency of 2.8MHz under normal pressure. The homogeneously mixed product was taken out and put into a DZF-6030 desktop vacuum drying oven for drying, the temperature was set at 20°C, and the drying time was 2.5 hours. After drying, grind to 20 meshes to obtain curing agent 12-HSA.

Abstract

The invention discloses a waste oil curing agent as well as a preparation method and application thereof. The waste oil curing agent is prepared from the following raw materials in percentage by weight: 85-94 percent of 12-hydroxy stearic acid, 2-6 percent of magnesium silicate monohydrate, 1-5 percent of starch and 4-8 percent of ethanol, and the total weight of the raw materials is 100 percent. The waste oil curing agent is simple and convenient in preparation process and can be produced in batches. The curing agent is a white powdery object, the curing agent is added into the kitchen waste oil on the premise that the combustion performance of the waste oil is not affected, a good curing effect on the kitchen waste oil is achieved, the problems that the kitchen waste oil leaks in the transportation process and flows back to a dining table are effectively solved, and the requirement for batch treatment of the kitchen waste oil can be met. Compared with products of the same type, the curing agent has the advantages of being high in dispersity and rapid in solidification, waste oil of the same type is solidified under the same condition, the solidification time of the curing agent can be shortened by about 20%, and the solidification efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of waste oil recovery and treatment, in particular to a waste oil curing agent, a preparation method and an application. Background technique [0002] The collection and transfer of kitchen waste oil has always been a thorny problem in the catering industry. Waste oil contains heavy metals such as lead, cadmium, and arsenic that seriously harm the human digestive system and nervous system, as well as the carcinogen sodium dodecylbenzene sulfonate. Aflatoxin B that is prone to cancer 1 . If kitchen waste oil enters the environment, it will cause sewer blockage and pipeline corrosion, serious water quality deterioration and eutrophication, reduce the treatment efficiency of the biological treatment unit of the sewage treatment plant, and it is prone to oxidative rancidity in the air, emitting acid odorous gas. According to reports, every kilogram of waste oil can cause 15000m 2 Water surface pollution can l...
