Description
Technical field
The present invention relates to a kind of polyurethane coatings and preparation method thereof, and in particular to a kind of polyurethane for shoes coating
Coating and preparation method thereof.
Background technique
Conventional article of footwear generally includes two main elements: vamp and footwear sole construction, it is generally the case that sole and shoes
What face was fabricated separately, sole is closely knit wear-resisting material, has waterproof performance；Vamp is made using leather or fabric, is guaranteed
Gas permeability.But in traditional shoes, if the height of sole is too low, water can be entered in shoes by seam and vamp, and galosh are
Using the shoes in the rainy day, the sole and vamp of galosh are integrated forms, and waterproof effect is fine, but vamp it is too closely knit and
Gas permeability is lost, outdoor sports are unfavorable for.Therefore a kind of vamp coating is needed, can be very good cladding sole and part vamp,
In the case where guaranteeing that sole is wear-resisting, moreover it is possible to it is waterproof, there is good gas permeability, while the material is there are also good appearance,
Convenient for Fashion Design.
Polyurethane paint is more typical a kind of coating at present, but paint due to containing a large amount of solvent (organic solvent or
Water), it is easy to it penetrates into inside the vamp of dry goods, vamp is caused to pollute losing functionality, in order to prevent to the infiltration of vamp,
It needs to do surface-closed processing, affects production efficiency.In addition, paint single track molding thickness is usually needed in 20-50 microns
The road 10-20 spraying process is wanted to can be only achieved the thickness of 0.2-2.0mm, per pass spraying process must wait preceding working procedures dry, solvent
Evaporating just can be carried out.Cause production efficiency extremely low in this way.Although paint can achieve required transparency simultaneously
And gloss, but wear-resisting property is very poor, is unable to reach required wear-resisting property.
For sole polyurethane elastomer have excellent abrasion resistant effect, but due to polyurethane material itself be easy with
The characteristics of moisture reacts, it is easy to generate a large amount of bubbles.To solve the problems, such as that polyurethane is easy to react with moisture, earliest by
The Dudley J.Primeaux II of Huntsman company takes the lead in researching and developing successfully spray Polyurea Elastomer Technology, sends out for the first time within 1989
Table research paper.The technology is commercially available in north America region within 1991, shows its excellent comprehensive performance immediately, by
User welcomes.The technology is applied to high-speed railway, aquatic products pond, swimming place and hall.Since polyureas has adhesive force strong, rub resistance, firmly
The features such as strong is spent, the high-end fields such as space flight, ordnance, ship, automobile are commonly applied to；But spray polyurea materials'use high-pressure spraying machine
Spraying, reaction speed is too fast, although itself is not reacted with the moisture in air, the air bubble trapped in spraying process due to
Reaction speed is too fast, can not escape out resin body, forms many small bubbles in the coating, cannot achieve desired
Obvious results fruit.In addition the aerosol caused by spraying can descend slowly and lightly in coating surface, form many short grained defects, it is also necessary to be beaten
Grinding and polishing light can be only achieved desired effect.
In addition, conventional polyurethane elastomer is difficult to realize the effect of high transparency, high brightness.The poly- ammonia made using polyethers
Ester elastomer is easy to get transparent effect, but its performance is difficult to abrasion resistant effect needed for meeting sole.Polyester production gathers
Urethane abrasion resistant effect is enough, but elastomer transparency is inadequate, it is difficult to meet desired demand.
Therefore, the prior art has much room for improvement.
Summary of the invention
The polyurethane coating and preparation method thereof that the purpose of the present invention is to provide a kind of for shoes coating, it is intended to overcome
