Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of method that utilizes waste oil to produce fatty acid zinc rubber plasticizer, to solve the lack of pre-treatment and post-granulation process steps in the prior art, can not meet the production of fatty acid zinc rubber plasticizer with waste oil as raw material In addition, because the purchase price of the main raw material palm oil is much higher than that of gutter oil, the price of direct imported fatty acid is higher, requiring a large amount of foreign exchange, which correspondingly increases the production cost of fatty acid zinc rubber plasticizer products, etc.

Embodiment 1

[0022] 1. Early oil treatment:

[0023] A. Freezing: freeze the waste oil raw material in a freezing container at a freezing temperature of -5°C for 3 hours;

[0024] B. Filtration: Filtrate the frozen waste oil raw material to obtain crystallized product A and non-crystallized product B;

[0025] 2. Hydrolysis:

[0026] The A and B products obtained in step 1 are hydrolyzed by physical hydrolysis, the hydrolysis pressure is 2.0Mpa, the hydrolysis temperature is 250°C, and the time is 10 hours; after hydrolysis, the A and B products are correspondingly converted into corresponding crude acids C and D.

[0027] 3. Distillation:

[0028] The crude acid C or D obtained in step 2 is placed in a distillation pot for negative pressure distillation at a temperature of 220 to 240° C., and the negative pressure and vacuum degree are negatively correlated with the temperature.

[0029] 4. Rough points:

[0030] The product of step 3 is roughly divided in a fractionation tower at a t...

[0036] 1. Early oil treatment:

[0037] A. Freezing: freeze the waste oil raw material in a freezing container at a freezing temperature of -15°C for 2 hours;

[0038] B. Filtration: Filtrate the frozen waste oil raw material to obtain crystallized product A and non-crystallized product B;

[0039] 2. Hydrolysis:

[0040] The A and B products obtained in step 1 are hydrolyzed by physical hydrolysis, the hydrolysis pressure is 2.5Mpa, the hydrolysis temperature is 220°C, and the time is 8 hours; after hydrolysis, the A and B products are correspondingly converted into corresponding crude acids C and D.

[0041] 3. Distillation:

[0042] The crude acid C or D obtained in step 2 is placed in a distillation pot for negative pressure distillation at a temperature of 220 to 240° C., and the negative pressure and vacuum degree are negatively correlated with the temperature.

Abstract

The invention relates to a method for preparing a zinc fatty acid rubber plastifier by using illegal cooking oil and belongs to the technical field of oleochemical industry. According to the preparation method, the illegal cooking oil is used as a main raw material, aiming at the characteristics of complex raw material components of the illegal cooking oil, the process steps of earlier stage treatment and granulation are added, the process steps of distillation and synthesis are improved to obtain the zinc fatty acid rubber plastifier with high purity, and other byproducts, such as crude acids and glycerol. The preparation method comprises the following process steps of: oil treatment in an earlier stage; hydrolysis; distillation; crude fractionating; synthesis; and granulation to obtain a granular zinc fatty acid rubber plastifier product. The abundant resource of the illegal cooking oil is fully utilized and is turned into wealth, the problem of social public hazards that the illegal cooking oil is used for cooking meals is solved, and the environmental pollution caused by abandoned illegal cooking oil is avoided. Since a matched process method for preparing the zinc fatty acid rubber plastifier by using the illegal cooking oil as the raw material is provided, the foreign exchanges for importing raw materials are saved, the production cost is reduced, the product quality is improved, and the process method has broad market prospect and great social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of oil chemical industry. Background technique [0002] Waste oil is a waste product of the catering industry, and it covers a large area. At present, there are no good waste utilization channels at home and abroad, resulting in the waste of a large amount of waste oil, causing serious environmental pollution. Some unscrupulous traders use the produced waste oil as food. Oil is served on the dining table, or used as edible oil raw material to produce various foods, which brings great harm to people's health. How to digest and process waste oil and turn waste into treasure has formed a serious social problem. [0003] Fatty acid zinc plasticizers are used as chemical raw materials in the rubber tire industry. At present, the conventional raw material for obtaining fatty acid zinc plasticizers at home and abroad is palm oil. Palm oil is used as raw material to produce crude acid, and then react with zinc oxide...
