Abstract
The invention discloses nanometer synthetic leather which comprises the following components: 80-99% of synthetic leather raw material and 1-20% of nanometer powder, wherein the nanometer powder is the mixture of nanometer silver and nanometer silicon dioxide. Through adding the nanometer materials in the synthetic leather, the invention not only keeps the original physical property of the common synthetic leather, but also greatly strengthens the abrasion resistance of the synthetic leather, protects the environment and prevents the bacteria, greatly prolongs the service life of the product, brings good glossiness without fading, and ensures that the cleaning is convenient.
Description
Technical field
The present invention relates to a kind of new material that is used for clothes, tame gorget territory, relate in particular to a kind of nanometer synthetic leather.
Background technology
Synthetic leather promptly is with PU slurry and corium fabric mixing manufacture together, is widely used.Synthetic 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 has wet and venting capability, in addition also more anti-dry-cleaning.Under same rigidity, than other elastomer bearing capacity height, the impact resistance height, the resilience scope is wide, is suitable for the high frequency deflection and uses, and the low temperature compliance is good.Synthetic leather has the performance that not corroded by ozone, and radiation hardness can be made flame-retardant materials.Synthetic leather can with timber, metal and most of plastic bonding, can be made into noise reduction sound material, but existing synthetic leather also exists defective, low such as abrasion resistance, there is not antibiotic function, face (dying) material ageing resistace is low, causes the indexs such as brightness, color harmony saturation degree of synthetic leather not reach customer requirement.
The Nano Silver material, be to utilize the forward position nanometer technology with silver-colored nanometer, make the sterilizing ability of silver under the nanometer state produce qualitative leap, few Nano Silver can produce powerful bactericidal action, can in several minutes, kill 650 various bacteria, and nano-Ag particles has superpower permeability.
Nano silicon is one of ultra tiny inorganic new material of extremely important high-tech, and because of its particle diameter is very little, specific area is big, and surperficial absorption affinity is strong, and surface energy is big, and aspect such as chemical purity height, dispersive property are good, thermal resistance, resistance has special performance.Because it is compared with conventional material at aspects such as magnetic, catalytic, light absorption, 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, battery, pigment, adhesive, cosmetics, fiberglass, chemical fibre, lucite, environmental protection.
Synthetic leather is combined with nano material, manage to form novel substance, the technology of development of new applications is the frontier of synthetic leather development.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of nanometer synthetic leather, has antibacterial environment protection, and abrasion resistance is far above common synthetic 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 synthetic leather, its composition and proportioning are as follows: synthetic leather raw material 80%-99%, nano powder 1%-20%, described nano powder are the mixture of Nano Silver and nano silicon.
The weight ratio of described Nano Silver and nano silicon is: 1: 5.
Add the nanometer pulvis of allotment by a certain percentage in the synthetic leather raw material,, the nanometer pulvis is blended in the raw material of synthetic leather equably, promptly make the nanometer synthetic 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 gay colours and very strong tinting strength, tinting power, and generally fast light, heat-resisting, anti-solvent and resistance to migration can be often not as good as inorganic pigments.By adding nanometer SiO2 organic face (dying) material is carried out surface modification treatment, face (dying) material ageing resistace is significantly improved, and raising to a certain degree also all appears in indexs such as brightness, color harmony saturation degree.
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 synthetic leather surface physical properties, has strengthened the abrasion resistance of synthetic leather itself by nano material is added synthetic leather greatly, environment-friendly antibacterial, prolonged the service life of product greatly, glossiness is difficult for fading well, and it is convenient to clean.
The specific embodiment
How further specify the present invention below in conjunction with specific embodiment realizes.
Will be further perfect after determining according to the weight ratio of Nano Silver and nano silicon.
Embodiment 1
The nanometer pulvis that in 80 kilograms of synthetic leather raw material, adds 20 kilograms, described nanometer pulvis is Nano Silver and nano silicon, the weight ratio of the two is 1: 5, through aftertreatment technology, the nanometer pulvis is blended in the raw material of synthetic leather equably, promptly makes nanometer synthetic leather of the present invention.
Embodiment 2
The nanometer pulvis that in 99 kilograms of synthetic leather raw material, adds 1 kilogram, described nanometer pulvis is Nano Silver and nano silicon, the weight ratio of the two is 1: 5, through aftertreatment technology, the nanometer pulvis is blended in the raw material of synthetic leather equably, promptly makes nanometer synthetic leather of the present invention.
Embodiment 3
The nanometer pulvis that in 90 kilograms of synthetic leather raw material, adds 10 kilograms, described nanometer pulvis is Nano Silver and nano silicon, the weight ratio of the two is 1: 5, through aftertreatment technology, the nanometer pulvis is blended in the raw material of synthetic leather equably, promptly makes nanometer synthetic leather of the present invention.
Claims (3)
1. nanometer synthetic leather, its composition and proportioning are as follows: synthetic leather raw material 80%-99%, nano powder 1%-20%, described nano powder are the mixture of Nano Silver and nano silicon, above-mentioned percentage all is weight percentage.
