Description
Technical field
The present invention relates to the manufacture method of superfine fiber chemical leather, relate in particular to a kind of preparation method of antibacterial and mouldproof superfine fiber chemical leather.
Background technology
Synthetic Leather has been applied to the every field in people's life at present, and is numerous in variety, and its medium-to-high grade superfine fiber chemical leather is fast-developing in recent years with the outward appearance of its physical property advantage and emulation skin.The wet process technique of traditional superfine fiber chemical leather is to be the dipping sizing agent immersion non-woven fabrics with the solvent borne polyurethane, in DMF (dimethyl formamide) aqueous solution, solidify then, extract out in the hot toluene groove, the washing oven dry, a large amount of DMF, toluene have wherein been used, all recovered solvent discharges contaminated environment with gas and waste water mode.Simultaneously Environmental Protection in China portion to the sewage discharge regulation toluene of leather industry, DMF content respectively at 0.1mg/L, below the 0.2mg/L.Though most of solvent can reclaim, the energy consumption that reclaims on the one hand solvent is also very high, still has partial solvent to reclaim on the other hand, has been discharged in the environment in the mode of gas and waste water.
Waterborne polyurethane resin is to be decentralized medium with water, has nontoxic, environmental protection, safety, advantage such as do not fire, and be the best substitute products of solvent type resin.There are very big policy and financial support in various countries to research and the application of aqueous polyurethane, China also drops into also bigger in the research of waterborne polyurethane resin with application, but the application of waterborne polyurethane resin on synthetic leather be some progress in recent years just comparatively speaking, main research concentrates on the surface finish of synthetic leather, have only the water-based dry method to move technology such as membrane technology and printing and be applied in the actual production, exploitation also is in the starting stage to aqueous polyurethane synthetic leather overall technology.Development along with the waterborne polyurethane resin technology, properties of product improve, international and domestic each relevant company also strengthened the application study input in recent years, the research that waterborne polyurethane resin prepares superfine fiber chemical leather obtained some progress in nearly 2 years abroad, Japan relies on advanced superfine fibre technology use polyurethane resin to prepare superfine fiber chemical leather, wherein fibre density is big, and shared superfine fibre is than great.Adopting the superfine fiber chemical leather key issue of impregnation aqueous polyurethane preparation with common superfine fibre nonwoven cloth at present is that the polyurethane fiber complex that forms does not contain microcellular structure, reach the feel of corium and higher physical property and need develop new technology.
At present, the major technique approach of antibacterial polyurethane synthetic leather is to add all kinds of antiseptics in prescription, realizes antibiotic effect.Technology is comparatively ripe, and the antiseptic with certain using value mainly contains inorganic antiseptic, manually 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 class antiseptic, simultaneously, the natural products antiseptic also is subjected to 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, organo-silicon compound, organic tin compound, amino acids metal salt and all kinds of quaternary ammonium salt, season phosphonium salt, guanidinesalt group graft polymers etc. of containing.As 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 class 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+Features 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 feature, has limited its application; Having only carrying silver antimicrobials to have high exploitation is worth.Chinese patent application CN1478817A has described a kind of polyurethane material that adds the inorganic nanometer oxide antiseptic, Chinese patent application CN1503660A has introduced the polyurethane film that silver-colored micropore compound antiseptic is carried in a kind of interpolation, and 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, in conjunction with Synthetic Leather moulding process characteristics, development novel antibacterial Synthetic Leather technology is this field developing direction from now on simultaneously.
