Embodiment 1

[0037] The citrus peel is cut into small pieces, these pieces are placed in a still with water, the mixture is distilled, and the distillate is collected in a collection vessel. Extract the distillate three times with dichloromethane, dry the combined extract with anhydrous sodium sulfate, then pour the liquid into a weighed Erlenmeyer flask with zeolite, and distill on a hot water bath to remove the solvent dichloromethane . When the volume was reduced to about 1 / 10 of its original volume, an appropriate amount of water was added and heating was continued for a few minutes to remove the last bit of dichloromethane to obtain liquid D-limonene.

[0038] Weigh 10Kg of the liquid D-limonene prepared by the above method, add 1Kg of alkyl phosphate, 2Kg of polyglycol oleate, 0.1Kg of sulfonated castor oil, and 0.5Kg of hexanediol to form phase A, 0.2Kg of C 5-6 and C 18-23 Synthetic fatty acid sodium soap, 0.2Kg C 10-16 Synthetic fatty acid monoethanolamine and 56Kg water are mi...

Embodiment 2

[0040] Extract D-limonene according to the method in Example 1, 56Kg liquid D-limonene and 5Kg alkyl phosphate, 7Kg oleic acid polyglycol ester, 1Kg sulfonated castor oil, 5Kg hexanediol are mixed into A phase, 1.5KgC 5-6 and C 18-23 Synthetic Fatty Acid Sodium Soap, 1Kg C 10-16 Synthetic fatty acid monoethanolamine and 23.5Kg water are mixed to form phase B, heat phase B to about 55°C, stir and add phase A, after high-speed stirring or colloid mill and other homogenizers, add flavor and other additives to obtain the finished product.

Embodiment 3

[0042] Extract D-limonene according to the method in Example 1, 30Kg liquid D-limonene and 3Kg alkyl phosphate, 5Kg oleic acid polyglycol ester, 0.5Kg sulfonated castor oil, 3Kg hexanediol are mixed into A phase, 1KgC 5-6 and C 18-23 Synthetic Fatty Acid Sodium Soap, 1Kg C 10-16 Synthetic fatty acid monoethanolamine and 56.7Kg water are mixed to form phase B, heat phase B to about 55°C, stir and add phase A, after high-speed stirring or colloid mill and other homogenizers, add flavor and other additives to obtain the finished product.

Abstract

The invention discloses an ink cleaning agent which comprises the components with the weight percentage: 1-5% of alkyl phosphoester. 2-7% of oleic acid poly-ethanol ester, 0.1-1% of sulfonated castor oil, 0.2-1.5% of C5-6 and C18-23 synthetic fatty acid sodium soap, 0.2-1% of C10-16 synthetic fatty acid monoethanol amine, 0.5-5% of hexamethylene glycol, 10-56% of D-limonene and 23.5-56% of water. The invention aims at overcoming the defects in the prior art, and provides the ink cleaning agent which is produced by the D-limonene extracted from the waste citrus fruit peel and has the advantages of non-toxicity, innocuity, zero emission, low production cost and high efficiency.

Description

technical field [0001] The present invention relates to an ink cleaning agent, more specifically, the present invention relates to an ink cleaning agent produced by utilizing D-limonene extracted from discarded citrus peels. Background technique [0002] At home and abroad, as an important industry, packaging and printing need to use a lot of cleaning agents in the normal production process. According to statistics, in 2006, the output value of printing enterprises in Guangdong Province alone reached 100 billion, and the annual consumption of printing ink cleaning agents exceeded 500 tons. , the harmful substance VOC discharged into the air reaches 450,000Kg, accounting for 13.8% of the atmospheric emission, causing serious pollution to the atmospheric environment, and at the same time causing harm to the nervous system and hematopoietic system of the user, affecting the development of the industry. [0003] In order to solve the above problems, a kind of non-toxic, non-poll...
