Water dam and building anti-seepage material and fabric coating etc..Adhesive has metal, glass, ceramics, leather, fiber etc.
Good adhesion strength.In addition polyurethane may also be fabricated which lotion, magnetic material etc..
At present, someone's research, which adds in inorganic antiseptic in high molecular material, achievees the effect that antibacterial, still, this
The inorganic antiseptic that method adds in is mostly Argent grain, and there is difficulties in dispersion, antibacterial effect plays slow (silver-series antibacterial agent performance effect
Fruit need to be when 24 is small more than) the shortcomings that.In recent years, the antibacterial prepared by adding suitable antiseptic in high molecular material
Material has caused the extensive concern of scholar.This emerging functional material itself, which has, inhibits and kills harmful microbe work(
Can, during its use, contact of the mankind with pathogenic bacteria can be effectively cut off, reduces the propagation of disease.In antibacterial material
Expect under the trend being widely used, the development of antiseptic is just becoming the hot spot of high molecular material addition auxiliary agent research field with exploitation
One of.Research, the exploitation of antiseptic start from early 1980s.At present, the antiseptic developed and applied can be classified as：It is organic
Antiseptic, inorganic antiseptic and complex antimicrobials three classes.
Antiseptic is a kind of new additive, it has widely in fields such as plastics, rubber, chemical fibre, ceramics, coating
Using its research and development and application are to reducing disease, protection human health has a very important significance, and meet wanting for era development
It asks.Although organic antiseptic sterilization speed is fast at present, good antimicrobial effect, its heat resistance is very poor, easily divides under high temperature
Solution, service life are short；The heat resisting temperature of inorganic antiseptic is higher, working life is long, but the occasion and condition that use have very
Big limitation.Organic/inorganic complex antimicrobials rationally utilize the advantages of the two, mutual by the synergistic effect between them and advantage
It mends, so as to greatly improve the performance of antiseptic and the scope of application, thus complex antimicrobials will become field development from now on
Important directions.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of light to stablize antibacterial polyurethane modified material system
Product solve the problems, such as that the service life of antiseptic is short and antibacterial effect is poor.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of light stablizes antibacterial polyurethane modified material product, and the product is including modified polyurethane plastic body and thoroughly
Bright waterproof layer；

The plastics composite is made of following component：
Content of the silver ion in modified polyurethane plastic body in the silver salt is 3-8wt%；
The transparent waterproof layer in modified polyurethane plastic body electrostatic spraying by forming.
Stablize the matter of outer layer the design transparent waterproof layer, wherein transparent waterproof layer of antibacterial polyurethane modified material product in light
Ground is identical with the resin of modified polyurethane plastic body, using identical material on raw material, avoids reacting between different materials
Or conjugation it is low the problem of, can effectively waterproof and extend usage time, the good water-proof effect of transparent waterproof layer, be avoided that it is antibacterial into
Silver ion is divided to be dissociated from product, so as to avoid the failure of fungistatic effect or reduction.
Antipathogenic composition selects silver ion, without using silver powder, wherein silver ion as ionic condition in the solution it is dispersed more
Good, the dispersiveness of silver powder in the solution is bad, silver powder so as to cause fungistatic effect it is uneven the problem of；Silver ion can be more uniform
It is distributed in product, fungistatic effect is uniform, and the preparation method of silver salt solution is also simpler than silver powder preparation process, it is easier to it operates,
Requirement to equipment is small, can effectively save process costs.
Polyurethane resin is for aviation, railway, building, physical culture etc.；For wood furniture and metallic surface Lacquer finish；
For basin, pipeline, freezer, beer, fermentation tank, preservation drum adiabatic heat-insulation cold insulation, building construction thermal insulation waterproof, it can also be used to
Prefabricated polyurethane plate；Available for manufacture plastic products, abrasive synthetic rubber product, synthetic fibers, hard and flexible foam modeling
Material products, adhesive and coating etc.；For all kinds of woodenware, chemical industry equipment, telecommunication apparatus and instrument and the table of various forms of transport
It covers with paint, lacquer, colour wash, etc. in face.Polyurethane resin as it is a kind of with high intensity, tear-proof, the characteristics such as wear-resisting high molecular material, daily life,
The fields extensive use such as industrial and agricultural production, medicine.Polyurethane elastomer be used as roller, conveyer belt, hose, auto parts, sole,
Synthetic leather, electric wire and medical artificial organ etc.；Flexible foam is for vehicle, room, the pad of clothes, rigid foam
Body is used as heat-insulated, sound-absorbing, packaging, insulation and low ratio foamed synthetic wood, and coating is prevented for advanced vehicle, furniture, wood and metal
Shield, pond dam and building anti-seepage material and fabric coating etc..Adhesive is to metal, glass, ceramics, leather, fiber etc.
There is good adhesion strength.In addition polyurethane may also be fabricated which lotion, magnetic material etc..
Further, the plastics composite is made of following component：

Further, the thickness of the transparent waterproof layer is 0.5-0.8mm.
The thickness of transparent waterproof layer is small, plays the role of waterproof in outer layer, and main material is identical, the compatibility of material
It is good.
The beneficial effects of the invention are as follows：
1. the outer layer for stablizing antibacterial polyurethane modified material product in light designs transparent waterproof layer, wherein transparent waterproof layer
Quality is identical with the resin of modified polyurethane plastic body, using identical material on raw material, avoids anti-between different materials
Should or conjugation it is low the problem of, can effectively waterproof and extension usage time, the good water-proof effect of transparent waterproof layer is avoided that antibacterial
Ingredient silver ion is dissociated from product；
2. antipathogenic composition selects silver ion, without using silver powder, wherein silver ion is dispersed in the solution as ionic condition
More preferably, silver ion can be more evenly distributed in product, and fungistatic effect is uniform, and the preparation method of silver salt solution is also than silver powder system
It is standby simple for process, it is easier to operate, the requirement to equipment is small, can effectively save process costs；
3. the polarity in antibacterial dispersant selection natural polymer with the substance wherein solvent of certain viscosity is big, it is easier to
Natural polymer is uniformly mixed so that the antiseptic that antibacterial dispersant and silver salt are prepared has good dispersed and certain
Viscosity, there is no the quality of resin is generated not so as to cause solvent greatly very much for two facial differences when being mixed with resin
Profit influences；
4. the selected as of auxiliary agent and filler more cheap substance of alternative costs on the premise of performance is ensured, wherein sliding
The cost of mountain flour and silica is low, and process costs can be reduced as filler；Ultraviolet ray ageing can be delayed by adding in antioxidant,
Extend the service life of resin.
