Description
Technical Field
The invention belongs to the technical field of cleaning solvents, and particularly relates to a dry cleaning solvent and a preparation process thereof.
Background
With the development of society, the living standard of people is continuously improved, the pace of life is continuously accelerated, the wearing and maintenance requirements of people on clothes are higher and higher, and convenience, sanitation, rapidness, leisure, diversification and individuation are continuously pursued, so that the vigorous development of industries such as dry cleaning, dyeing, renovation, perfuming and beauty treatment of the clothes is driven. Dry cleaning refers to a method of washing clothes using a chemical solvent, which makes up for the defects of shrinkage, fiber hardening and the like of silk and wool fabrics in the washing process, thereby rapidly developing in recent decades.
The two largest dry cleaning solvents used worldwide are tetrachloroethylene (PERC) and petroleum. Tetrachloroethylene has high cleaning power, low cost, non-flammability and good chemical stability. However, tetrachloroethylene has two major disadvantages: the problems brought by the method to personal safety and environmental protection are as follows: it can cause damage to human organ systems such as liver, kidney, skin and nerve after entering human respiratory tract; and because the waste can not be naturally degraded, the waste can be accumulated over time to cause the problem of serious industrial hazardous waste disposal, thereby causing influence on the environment. (II) the "dissolving" capacity of tetrachloroethylene is sometimes too high to damage accessories on the garment, such as beads, paillettes, metal and buttons.
The traditional petroleum solvent can also damage the living environment and cause harm to the body of the dry cleaning worker; it is flammable and explosive in use and storage, and has great danger; petroleum solvents can also damage textile fibers and some parts of clothing.
The pure silicone oil dry cleaning agent has poor detergency, slow drying speed and large power consumption; the pure alcohol ether solvent is slow to dry, high in use cost and not ideal in detergency.
Cyclic silicones have enjoyed some commercial success as dry cleaning solvents replacing tetrachloroethylene and petroleum. It is much better than tetrachloroethylene and petroleum in fabric care, especially in reducing damage to textile fibers, textile dyes and finishes, and clothing accessories. Its safety is greatly improved compared with tetrachloroethylene and petroleum, and it has unique fire-resisting property, so that it is safe in the course of use and storage: it has a flash point and a fire point separated by at least 10 degrees Fahrenheit and is a self-extinguishing solvent.
In summary, there is a need in the dry cleaning industry to invent components and methods of use for new dry cleaning solvent systems that provide efficient removal of both hydrophilic and hydrophobic stains and provide excellent fabric care.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a dry cleaning solvent and a preparation process thereof, and solves the technical problems of poor detergency, low drying speed, high power consumption, high cost and the like in the prior art.
In order to solve the problems, the technical scheme of the invention is as follows: a dry cleaning solvent and a preparation process thereof are prepared from the following raw materials in parts by weight: 60-90 parts of alkane solvent and 6-40 parts of other solvents; the other solvent is an ether ester solvent or an alcohol ether solvent or a mixture of the ether ester solvent and the alcohol ether solvent;
the ether ester solvent is one or more of propylene glycol monomethyl ether formate, propylene glycol monomethyl ether acetate, propylene glycol monomethyl ether propionate, propylene glycol monomethyl ether butyrate, propylene glycol monoethyl ether formate, propylene glycol monoethyl ether acetate, propylene glycol monoethyl ether propionate and propylene glycol monoethyl ether butyrate;
the alcohol ether solvent is one or a mixture of dipropylene glycol methyl ether, dipropylene glycol dimethyl ether, tripropylene glycol methyl ether, propylene glycol dimethyl ether and propylene glycol methyl ether;
the alkane solvent is one or a mixture of more than one of isoparaffin and environment-friendly petroleum dry cleaning agent;
a preparation process of a dry cleaning solvent comprises the following steps: sequentially adding 60-90 parts by weight of alkane solvent and 6-40 parts by weight of other solvents into a stirrer, and strongly stirring for 30 minutes to fully dissolve the other solvents so as to obtain a dry cleaning solvent;
further, the other solvent is 6-40 parts by weight of an ether ester solvent.
Further, the other solvent is a mixture of 6-40 parts by weight of alcohol ether solvents.
Further, the other solvent is a mixture of 3-20 parts by weight of an ether ester solvent and 3-20 parts by weight of an alcohol ether solvent.
The present invention has the characteristic of dissolving both water-soluble dirt and oil-soluble dirt. The components of the detergent contain petroleum alkane solvents, and the detergent has good dissolubility on petrochemical and grease dirt according to the similar intermiscibility theory; the alcohol ether component has unique dissolving effect on water-soluble dirt. Meanwhile, the synergistic effect of various solvents ensures that the decontamination characteristics such as kb value, safety, water solubility, drying speed and the like of the detergent are better than the single use effect of several products.
