Dry cleaning agent for clothes and preparation method of dry cleaning agent

Abstract

The invention provides a dry cleaning agent for clothes and a preparation method of the dry cleaning agent. The dry cleaning agent comprises polyethylene glycol oleate, benzotriazole, polyethylene glycol, polyethylene glycol mono C12-18 alkyl ether sodium phosphate, polyethylene glycol mono C12-18 alkyl ether, 2-benzyl-4-chlorophenol, sulfuric castor oil, dioctylsulfosuccinate sodium salt, octaphenyl polyoxyethylene ether, lactate, propylene glycol monomethyl ether, sodium dioctyl sulfosuccinate, sodium tripolyphosphate, sodium silicate and deionized water. The preparation method comprises steps as follows: firstly, the polyethylene glycol oleate, the benzotriazole, the polyethylene glycol, the 2-benzyl-4-chlorophenol, the octaphenyl polyoxyethylene ether and the propylene glycol monomethyl ether are added to the sulfuric castor oil, and a mixed liquid I is obtained; rest components are added to the deionized water, and a mixed liquid II is obtained; finally, the mixed liquid I is added to the mixed liquid II while stirring, and the dry cleaning agent is obtained. The dry cleaning agent is convenient and quick to use, good in decontamination effect, pollution-free and non-toxic and is an excellent environment-friendly dry cleaning agent.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a laundry dry-cleaning agent and a preparation method thereof. Background technique [0002] Fabric dry cleaning is a dry-in-dry-out washing method that uses organic chemical solvents to wash fabrics and remove oil stains or stains. Since the water does not directly contact the fabric during washing, it is called dry cleaning. The main feature of dry cleaning is to avoid damage to the fabric caused by washing, no shrinkage, no deformation, good color protection, not easy to cause fabric fading, soft to the touch, easy to iron and can thoroughly clean oil or stains on the fabric. After washing, the fabric also has the special effect of disinfection and sterilization, which is not easy to be eaten by insects and is convenient for preservation. [0003] Currently widely used dry cleaning agents include the following four categories: petroleum solvent dry clea...

Problems solved by technology

It uses the two-state change of carbon dioxide to add necessary additives to wash clothes. Practice has proved that using liquid carbon dioxide to wash clothes can effectively remove all kinds of dirt, including greasy dirt, and even some special dirt. However, If it is applied to practice, there are still many problems to be solved. For example, the two-state conversion of carbon dioxide needs to be carried out in a high-pressure container, so the washing chamber must withstand a pressure of 6MPa-7MPa

The transportation and circulation of liquid carbon dioxide require special operation of high-pressure pumps, how to put additives in the washing process, etc., so it is difficult to popularize and use

[0007] Tetrachlorethylene is a solvent with strong degreasing power, which has a good dissolving effect on grease. It is widely used in the dry cleaning industry at present, but it has certain toxicity and will pollute the soil and water quality. Regular contact with tetrachlorethylene will cause Dizziness, headache, vertigo, nausea and vomiting symptoms, acute inhalation will show eye, nose and throat irritation symptoms, long-term exposure may cause central nervous system, liver and kidney damage

[0008] The above-mentioned dry cleaning agents have a strong ability to remove oil-soluble dirt on clothing, and can effectively remove granular solids, but their ability to remove water-soluble dirt is poor, and dirt recontamination will occur during the dry cleaning process , the effect on light-colored clothing is more prominent

Therefore, in order to further improve the quality of dry cleaning, the prior art has carried out a large number of special studies on dry cleaning agents, and has successively disclosed a variety of high detergency dry cleaning agents that are less harmful to the environment and the human body, but have not found an ideal substitute all the time.
