Description
Technical field
The present invention relates to a kind of Synthetic Leather material and preparation method thereof, be specifically related to Synthetic Leather material with antibacterial and antimildew function and preparation method thereof.
Background technology
Synthetic Leather is the macromolecular material that a class has property, has the excellent properties such as outstanding ABRASION RESISTANCE, intensity and toughness, solvent resistance, oil resistivity, high cutting rate.Nineteen fifty-three, first Germany applied for Synthetic Leather patent, and the sixties in 20th century starts and commercially produces.At present, Synthetic Leather material is widely used in the fields such as sports play shoes, leather shoes, leather wear, case and bag, sofa furniture, waistband, ticket-holder, stationery, automotive trim and medicine equipment manufacture.Since China introduced Synthetic Leather dry production technology first from 1981, Synthetic Leather slurry production capacity is more than 8000 tons/year.Since 21 century, along with rapid economic development, increasing to the demand of Synthetic Leather.
Today, Synthetic Leather goods are throughout the every aspect of our productive life, large to space flight military project, little of daily life, do not use Synthetic Leather product nowhere.But in recent years, due to reasons such as process, using method or placement storage requirements, various Synthetic Leather goods in use in the near future, occur that material surface goes mouldy, crack performance, so that cannot use and lose value.Trace it to its cause, wherein topmost be exactly the microorganisms such as mould, bacterium, fungi under optimum conditions, amount reproduction on polyurethane surface, and its secretion causes the biodegradation of high polymer, makes polyurethane epithelium occur crackle.Meanwhile, because polyurethane leather surface grows a large amount of bacterium, mould, exacerbate diffusion and the propagation of various diseases, huge threat is caused to health.Along with the development of economic technology, the attention of people to health reaches unprecedented height, thus develop a kind of have safety, high-efficiency antimicrobial, fungicidal properties new polyurethane synthetic leather technology just become the active demand of industry development instantly.
At present, the Major Technology of antibacterial polyurethane synthetic leather adds all kinds of antiseptic in formula, realizes antibiotic effect.Technology is comparatively ripe, and the antiseptic with certain using value mainly contains inorganic antiseptic, Prof. Du Yucang organic antibacterial agent, polymer antibacterial agent and natural products antiseptic.Wherein natural products antiseptic is animals and plants extracts, mainly contain the Chitosan powder of hyperfine structure, chitin kind and various plant secretion things etc., but there is the defects such as poor heat resistance, duration of efficacy be short in this kind of antiseptic, simultaneously, natural products antiseptic is also subject to factor of natural environment impact, and be difficult to reach volume production scale, commercial application value is lower.Organic antibacterial agent and polymer antibacterial agent are mainly all kinds of organic nitrogen-containing ionic compound, organo-silicon compound, organic tin compound, amino acids metal salt and all kinds of containing quaternary ammonium salt, season phosphonium salt, guanidine salt groups graft polymers etc.As China Patent Publication No. CN2672973, CN3362140 describe the polyurethane material anti-microbial property adding organic antibacterial agent respectively.Although it is strong that this kind of antiseptic has sterilizing ability, also there is this poor heat resistance in the advantages such as the response time is short, with strong points, facile hydrolysis sex change, and broad-spectrum antibacterial property is poor, and volatility is large, and has the problems such as certain toxicity, so limit its application.The porous nano compound of inorganic antiseptic mainly all kinds of years silver, copper, zinc ion, nano-metal-oxide, as: TiO
2, ZnO, SiO
2deng material, wherein carry Ag
+, Cu
2+, Zn
2+cationic inorganic nano material has has a broad antifungal spectrum, the features such as excellent antibacterial performance, becomes rapidly the new lover in the antibacterial field of macromolecular material, particularly Ag in recent years
+ion, its antibacterial activity is more than Zn
2+1000 times, ion; Cu
2+the characteristic aquamarine blue of ion tool, limits its application; Carrying silver antimicrobials is only had to have high Development volue.Chinese patent application CN1478817A describes a kind of polyurethane material adding inorganic nanometer oxide antiseptic, Chinese patent application CN1503660A describes a kind of polyurethane film adding year silver-colored containing Microporous Compounds antiseptic, and Chinese patent application CN1673246A describes a kind of fabricating technology adding the antibacterial polyurethane foamed plastics of inorganic antiseptic.But it is long that inorganic antiseptic also exists sterilization, antibacterial response time equally, easily causes the problem of product variable color.
The advantages such as comprehensive inorganic antimicrobial agent stability is strong, has a broad antifungal spectrum, antimicrbial power lasting and the organic antibacterial agent response time is short, with strong points in one inorganic/organic composite antibiotic agent, simultaneously in conjunction with Synthetic Leather moulding process feature, Development of Novel antibacterial polyurethane synthetic leather technology is this field developing direction from now on.
