Embodiment 1

[0034] The preparation method of waste oil alkyd comprises the steps:

[0035] Step 1: Measure 459.8g of waste oil, add it to the reaction kettle, heat and stir;

[0036] Step 2: When the temperature is raised to 285°C at a constant speed for 1.5-2 hours, add 124.5g of isophthalic acid and continue to raise the temperature;

[0037] Step 3: When the temperature is raised to 285°C at a constant speed for 5-6 hours, start to keep warm;

[0038] Step 4: After keeping warm for 1.5 hours, take a sample to test the acid hydrolysis; if the material remains clear when it cools down to 250°C, the acid hydrolysis has reached the equilibrium end; if the material is turbid, continue to keep warm, and test the acid hydrolysis every half an hour The material is clear and transparent at 250°C;

[0039] Step 5: After the material is clear and transparent at 250°C, and the acid hydrolysis reaches the equilibrium end point, cool down;

[0040] Step 6: When the temperature is lowered to 220°C...

Embodiment 2

[0050] On the basis of Example 1, while adding trimethylolpropane in step 6, add AT-1. Catalyst AT-1 is a compound mixture containing tin octoate and phosphite, mixed according to the equivalent ratio of 2:1, which can greatly promote the esterification of oil components with poor reactivity in alkyd resins. It also contributes to the color retention of alkyds.

[0051] According to the previous experiment, the experiment added AT-1 to the alkyd synthesized from waste oil, compared with linseed oil and soybean oil.

[0052] Table 2

[0053]

[0054] Through this test, it can be considered that the introduction of AT-1 has played a very important auxiliary role in the esterification of alkyd, greatly improving the reactivity of waste oil and making alkyd in waste oil possible.

[0055] The addition of AT-1 catalyzer has largely solved the drawback of reducing the reactivity brought by waste oil. Because the components in the waste oil are relatively complex, the reactivit...

Embodiment 3

[0057] In order to further verify the performance of waste oil alkyd, we tested three kinds of alkyd in the ink.

[0058] Apply them in the same ratio to the formulation of the binder V338, and use the same process to refine the resin oil.

[0059] In one embodiment, the waste oil alkyd obtained in embodiment 2 is applied to configuration ink, configuration method is as follows:

[0060] Step 1. In a four-neck flask equipped with a mixer and a thermometer, add 78 grams of linseed oil, 30 grams of tung oil, and 32 grams of SJ-5AF mineral oil, and heat evenly to 200 ° C;

[0061]Step 2: Add 215 grams of R2300 resin in batches to dissolve it completely, control the temperature at 200°C, and keep it warm for half an hour;

[0062] Step 3: Add 150 grams of SJ-5AF mineral oil and 62 grams of waste oil alkyd resin to cool down to 150 °C.

[0063] Step 4: Add 5.4 grams of K1541 liquid gel, heat up to 180°C, and keep warm for one hour;

[0064] Step 5. After the heat preservation is...

Abstract

The invention discloses a hogwash oil alkyd preparation method, which comprises: 1, metering 459.8 g of hogwash oil, adding into a reaction kettle, and heating while stirring; 2, uniformly heating for1.5-2 h to achieve a temperature of 285 DEG C, adding 124.5 g of meta-phthalic acid, and continuously heating; 3, uniformly heating for 5-6 h to achieve a temperature of 285 DEG C, and carrying out thermal insulation; 4, carrying out thermal insulation for 1.5 h until the material is transparent and clarified at a temperature of 250 DEG C; 5, cooling; 6, adding 81.3 g of trimethylolpropane and 0.5 g of AT-1 after cooling to a temperature of 220 DEG C, and slowly heating; 7, uniformly heating for 4-5 h to achieve a temperature of 270 DEG C, and carrying out thermal insulation; 8, carrying outthermal insulation for 2 h, sampling, and measuring the acid value and the rotational viscosity of the material; and 9, cooling if the acid value and the rotational viscosity meet indexes, and discharging the material. According to the present invention, with the preparation method, the production is stable, and by adding the catalyst, the disadvantage of the reaction activity reducing caused by the use of the hogwash oil is solved to a great degree.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to a preparation method and application of waste oil alkyd. Background technique [0002] Waste oil is a general term for various inferior oils in people's daily life. Including the oil extracted from the greasy floating matter in the sewer or the swill of hotels and restaurants through simple processing. After frying at high temperature for a long time and repeated use, fats and oils will form carcinogens such as aflatoxin and benzopyrene. Long-term consumption of recovered waste oil will cause great harm to human health. But it is a pity that a large amount of waste oil is discarded. [0003] The existing method for preparing alkyd from waste oil has low production efficiency and poor reactivity, and it is difficult to meet market demands. [0004] The present invention adopts waste oil to synthesize alkyd resin, which not only avoids waste oil being returned to the dining table, b...
