Description
Technical field
The invention belongs to mirror surface leather technical field, be specifically related to a kind of UV and solidify solvent-free height saturating non-yellow stain polyurethane minute surface
Resin and preparation method thereof.
Background technology
Along with the raising day by day of our people's living standard, people are increasingly wider to the demand of consumer goods, therefore high transparency
High performance case and bag, footwear demand are increasing.
Traditional mirror surface leather is mainly prepared by two ways, and one is exactly dry method veneer, solvent-borne type slurry is scratched in
Above mirror surface paper, dry out solvent uses solvent-borne type bed material laminating bass again, and this process uses the poisonous and harmful solvents such as DMF in a large number.Phase
Than with do mirror surface leather, the mirror surface leather planarization of moisture-curable gained and brightness by dry method veneer and to exceed a lot, the highest
The mirror surface leather of end is substantially to be prepared by moisture-curable, but the production process environment of moisture-curable is very severe, and
And extremely inefficient, preparation method is solvent-borne type slurry to add after a large amount of solvent dilution showering to leather surface, stands and makes solvent natural
Volatilization, the solvent of 90% evaporate in air, needs the cool system of room temperature 24 hours, and production process needs dedusting, it is necessary to airtight,
Can not ventilate, operator are injured and huge, simultaneously because whole space is full of inflammable and explosive solvent, therefore dangerous
Also very big, additionally from being to react solidification by isocyanates and water due to moisture-curable product, therefore goods resistance to low temperature is poor,
The product that low temperature complications are required by footwear etc. cannot be done.Therefore in people's growing interest health and today of environmental protection, exploitation one
Solvent-free height without any organic solvent, pollution-free, high efficiency, low energy consumption and physical properties excellent is thoroughly without xanthochromia mirror surface leather tree
Fat is the most meaningful.
Resin is coated in base fabric solidification by UV curing of the prior art, then carries out veneer with water-base resin, tool
There are the features such as curing efficiency height, environmental friendliness, energy consumption are low, but use the method for water-base resin veneer not simply fail to accomplish high lens
Upper leather effect, and add energy consumption and cost.
Summary of the invention
Goal of the invention: it is an object of the invention to provide a kind of UV and solidify solvent-free height saturating non-yellow stain polyurethane minute surface resin
Being entirely free of the environment-friendly polyurethane minute surface resin of any organic solvent, its physical property exceedes dry method veneer and moisture-curable mirror
Face, production efficiency is high, can be with instantaneous solidification molding.It is a further object of the present invention to provide the preparation method of this resin.
