Abstract
The invention discloses a nano PU imitation leather which is composed of the following components: 80-99% of PU imitation leather raw material slurry, and 1-20% of nano powder, wherein the nano powder is the mixture of nano silver and nano silica. Nano material is added to the PU imitation leather, thereby not only keeping the original physical properties of common PU imitation leather, but also largely strengthening the abrasion resistance of PU, being environmental and antibacterial, and largely prolonging the use life of products. Besides, the nano synthetic leather achieves good glossiness, hardly fades, and is convenient to wash.
Description
Technical field
The present invention relates to a kind of novel material that is used for clothes, tame gorget territory, relate in particular to a kind of nanometer PU simulated leather.
Background technology
The PU simulated leather promptly is to be the leatheroid of raw material production with the PU resin, is widely used.Common PU simulated leather is applied to clothes, and family's decorations wait numerous areas, and its coating is soft and flexible, and strength of coating is good, can be used for very thin coating.Its coating possesses porousness, has wet and venting capability, in addition also more anti-dry-cleaning.Under same rigidity, than other elastomerics supporting capacity height, the shock resistance height, the resilience scope is wide, is suitable for the high frequency deflection and uses, and the low temperature kindliness is good.The PU simulated leather has and is not subjected to ozone erosive performance, and radiation hardness can be made flame-retardant materials.The PU simulated leather can with timber, metal and most of plastic bonding, can be made into noise reduction sound material, but existing P U simulated leather also exists defective, low such as fastness to rubbing, there is not antibiotic function, face (dying) material ageing resistance is low, causes the indexs such as brightness, color harmony saturation ratio of PU simulated leather not reach customer requirement.
The nanometer silver material, be to utilize the forward position nanotechnology with silver-colored nanometer, make the sterilizing ability of silver under the nanometer state produce qualitative leap, few nanometer silver can produce powerful germicidal action, can in several minutes, kill 650 various bacteria, and nano-Ag particles has superpower perviousness.
Nano silicon is one of ultra tiny inorganic novel material of extremely important high-tech, and because of its particle diameter is very little, specific surface area is big, and surface adsorption power is strong, and surface energy is big, and aspect such as chemical purity height, dispersing property are good, thermal resistance, resistance has special performance.Because it is compared with conventional material at aspects such as magnetic, catalytic, photoabsorption, thermal resistance and fusing points and demonstrates exceptional function, thereby obtains people's very big attention.It is widely used in numerous areas such as rubber, plastics, electronics, coating, pottery (warding off) porcelain, gypsum, store battery, pigment, tackiness agent, makeup, glass reinforced plastic, chemical fibre, synthetic glass, environmental protection.
The anti-leather of PU is combined with nano material, manage to form novel substance, the technology of development of new applications is the frontier of the anti-leather development of PU.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of nanometer PU simulated leather, has antibacterial environment protection, and fastness to rubbing is far above common simulated leather material, long service life, and glossiness is difficult for fading well, cleans advantages such as convenient.
Goal of the invention of the present invention is achieved by the following technical solution:
A kind of nanometer PU simulated leather, its composition and proportioning are as follows: PU simulated leather raw material slurry 80%-99%, nano powder 1%-20%, described nano powder are the mixture of nanometer silver and nano silicon.
The weight ratio of described nanometer silver and nano silicon is 1: 5.The thickness of nanometer silver is 50-100nm, and length is the 1-5 micron, and the particle size range of nano silicon is: the 0.5-10 micron.
Add the nanometer pulvis of allotment by a certain percentage in the PU simulated leather raw material slurry,, the nanometer pulvis is blended in the starting material of PU simulated leather equably, promptly make nanometer PU simulated leather through aftertreatment technology.
Process studies have shown that it possessed following effect when nano silicon was used for face (dying) material: organic face (dying) is though material has bright colour and very strong tinting strength, and generally fast light, heat-resisting, anti-solvent and resistance to migration can be often not as good as mineral dyes.By adding nanometer SiO2 organic face (dying) material is carried out surface modification treatment, face (dying) material ageing resistance is significantly improved, and raising to a certain degree also all appears in indexs such as brightness, color harmony saturation ratio.
Nano-Ag particles can directly enter thalline and oxygen metabolism, and (SH) combine, the unique effect mechanism that thalline is choked to death can be killed microorganisms such as most of bacteriums of being in contact with it, fungi, mould, spore.
The present invention under the prerequisite of not destroying nanometer PU simulated leather surface physical properties, has strengthened the fastness to rubbing of PU itself by nano material being added the PU simulated leather greatly, environment-friendly antibacterial, prolonged the work-ing life of product greatly, glossiness is difficult for fading well, and it is convenient to clean.
