Abstract
The invention discloses a self-cleaning oil resistant finishing agent which comprises the following components in parts by weight: 70-80 parts of nanometer titanium dioxide, 10-15 parts of octadecyl phenol, 5-8 parts of dimethyl hydrogen-containing polysiloxane, 5-10 parts of cationic surface active agent, and 0.2-1 part of sodium polyacrylate dispersing agent. According to the invention, fabric treated by adopting the self-cleaning oil resistant finishing agent can have both the self-cleaning performance and oil rub resistance, and is excellent in durability.
Description
Technical field
The present invention relates to a kind of automatically cleaning anti oil agent, and the preparation method of this finishing agent.
Background technology
Utilize nano-TiO
2photodegradation, can effectively remove the part harmful substance.Nano-TiO
2under the irradiation of ultraviolet ray or daylight, can be by oxychloride, formaldehyde catalytic degradation.Its principle is TiO
2when being subject to the ultraviolet ray irradiation, will produce free electron and hole, they make airborne oxygen activation, produce reactive oxygen species and free radicals, and some organic pollution is decomposed into CO the most at last
2and H
2o.Contain nano-TiO
2non-weaving cloth or textiles, can make curtain, sheet, wall paper, carpet, furniture and cloth, various adornments etc. for car and boat, also can be used as the purified treatment articles for use of air and waste water.But prior art adopts direct method for sorting, due to nano-TiO
2interfacial effect, itself and fibrous binding force are not strong, cause the durability of finished product and water-wash resistance poor, affect its result of use.Develop a kind of automatically cleaning anti oil agent with excellent durability and become important research topic.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of automatically cleaning anti oil agent, the above-mentioned defect existed to overcome prior art.
For solving the problems of the technologies described above, automatically cleaning anti oil agent of the present invention is comprised of the component of following weight portion:
As preferred version, the average grain diameter of described nano titanium oxide is the 50-100 nanometer; Preferred nanometer anatase titania;
The quantity of the siloxy repetitive of described dimethyl hydrogen containing siloxane is 40-50;
Described Sodium Polyacrylate dispersant preferred viscosities 200-250mPas;
Described cationic surfactant comprises one or more in dodecyl benzyl dimethyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, cetalkonium chloride, stearyl dimethyl benzyl ammonium chloride, hexadecyltrimethylammonium chloride, softex kw, hexadecylpyridinium chloride.
The automatically cleaning anti oil agent can adopt general mixed method, preferably adopts following method preparation:
Nano titanium oxide, octadecyl phenol, dimethyl hydrogen containing siloxane, Sodium Polyacrylate dispersant and water are mixed and is made into the water slurry that mass content is 20-60%, then add cationic surfactant at twice in suspension, add for the first time 50% cationic surfactant, add for the second time remaining cationic surfactant, need respectively to mix 0.5-3.0 hour after adding cationic surfactant for twice.
The present invention adds cationic surfactant in the nano titanium oxide water slurry, and cationic surfactant one end is the CATION that polarity is very strong, and the other end is the very weak longer hydrocarbon chain of polarity.Cationic surfactant adds at twice, after surfactant adds for the first time, CATION one end that surfactant polarity is very strong and the anion generation effect on nano titanium oxide surface, SURFACTANT ADSORPTION is to the titanium dioxide nanoparticle surface, by other end polarity, very weak long-chain hydrocarbon covers the titanium dioxide nanoparticle surface, makes the titanium dioxide nanoparticle surface become low pole.After surfactant adds for the second time, surfactant low pole long-chain hydrocarbon can with the generation effect of the titanium dioxide nanoparticle of low pole surface, the surface of very strong cation nanometer titanium dioxide granule by other end polarity, make positive charge on original electronegative titanium dioxide nanoparticle surface band, make nano titanium oxide become cationic.The cation nanometer titanium dioxide of this surface band positive charge, can with fabric surface with negative electrical charge produce strong effect, make titanium dioxide nanoparticle be adsorbed on firmly fabric surface.Add octadecyl phenol and dimethyl hydrogen containing siloxane in the automatically cleaning anti oil agent, can be effectively to oil rub resistance.Durability of the present invention is strong, has good automatically cleaning and functions.
