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 that has antibacterial and antimildew function and preparation method thereof.
Background technology
Synthetic Leather is one type of macromolecular material with property, has excellent properties such as outstanding ABRASION RESISTANCE, intensity and toughness, solvent resistance, oil resistivity, high cutting rate.Nineteen fifty-three, Germany at first applied for the Synthetic Leather patent, and begun to commercially produce the sixties in 20th century.At present, the Synthetic Leather material is widely used in fields such as sports play shoes, leather shoes, leather wear, case and bag, sofa furniture, waistband, ticket-holder, stationery, automotive trim and medicine equipment manufacturing.China is since 1981 introduce Synthetic Leather dry production technology first, and Synthetic Leather slurry production capacity is above 8000 tons/year.Since 21 century,, increasing to the demand of Synthetic Leather along with rapid economic development.
Today, the Synthetic Leather goods spread all over the every aspect of our productive life, arrive the space flight military project greatly, and are little of daily life, do not use the Synthetic Leather product nowhere.Yet in recent years, owing to process, method for using or place reason such as storage requirement, various Synthetic Leather goods are using in the near future, occur that material surface goes mouldy, crack performance, lose value so that can't use.Trace it to its cause, wherein topmost be exactly microorganisms such as mould, bacterium, fungi under optimum conditions, breeding in a large number on polyurethane surface, and its secretion causes the biodegradation of high polymer, makes the polyurethane epithelium crackle occur.Simultaneously,, aggravated the diffusion and the propagation of all kinds of diseases, health has been caused huge threat because the polyurethane leather surface grows a large amount of bacteriums, mould.Along with the development of economic technology, people have reached unprecedented height to the attention of health, just become the active demand of industry development instantly so develop a kind of new polyurethane synthetic leather technology with safety, high-efficiency antimicrobial, fungicidal properties.
At present, the major technique approach of antibacterial polyurethane synthetic leather is in prescription, to add all kinds of antiseptics, realizes antibiotic effect.Technology is comparatively ripe, and the antiseptic with certain using value mainly contains inorganic antiseptic, artificial synthetic organic antibacterial agent, polymer antibacterial agent and natural products antiseptic.Wherein the natural products antiseptic is the animals and plants extracts; Mainly contain the shitosan powder of hyperfine structure, chitin kind and various plant secretion things etc., but there are defectives such as poor heat resistance, duration of efficacy weak point in this type antiseptic; Simultaneously; The natural products antiseptic also receives the factor of natural environment influence, is difficult to reach the volume production scale, and commercial application value is lower.Organic antibacterial agent and polymer antibacterial agent are mainly all kinds of organic nitrogen-containing ionic compounds, and organo-silicon compound, organic tin compound, amino acids metal salt and all kinds of contain quaternary ammonium salt, season phosphonium salt, guanidinesalt group graft polymers etc.Like Chinese patent publication number CN2672973, CN3362140 has introduced the polyurethane material anti-microbial property that adds organic antibacterial agent respectively.Though also there is this poor heat resistance in advantages such as it is strong that this type antiseptic has a sterilizing ability, and the response time is short, and is with strong points, the facile hydrolysis sex change, broad-spectrum antibacterial property is poor, and volatility is big, and problem such as certain toxicity is arranged, so limited its application.Inorganic antiseptic mainly is the porous nano compound of 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+Characteristics such as the ion inorganic nano material has has a broad antifungal spectrum, and anti-microbial property is good become the new lover, particularly Ag in the antibiotic field of macromolecular material in recent years rapidly
+Ion, its antibacterial activity surpasses Zn
2+1000 times in ion; Cu
2+Ion has the aquamarine blue of characteristic, has limited its application; Having only carrying silver antimicrobials to have high exploitation is worth.One Chinese patent application CN1478817A has described a kind of polyurethane material that adds the inorganic nanometer oxide antiseptic; One Chinese patent application CN1503660A has introduced a kind of polyurethane film that adds silver loaded micropore compound antiseptic, and one Chinese patent application CN1673246A has described a kind of fabricating technology that adds the antibacterial polyurethane foamed plastics of inorganic antiseptic.But it is long that inorganic antiseptic exists sterilization, antibacterial response time equally, causes the problem of product variable color easily.
Advantages such as comprehensive inorganic antiseptic stability is strong, has a broad antifungal spectrum, antimicrbial power is lasting and the organic antibacterial agent response time is short, with strong points are in the inorganic/organic composite antibiotic agent of one; Combine Synthetic Leather moulding process characteristics simultaneously, development novel antibacterial Synthetic Leather technology is this field developing direction from now on.
