Abstract
It is to cover with paint, lacquer, colour wash, etc. one layer of silane coating material in polyurethane-base basal surface and solidify, silane coating material is to blend the silane that one or more are not pre-condensed or part is pre-condensed with reactant the present invention relates to a kind of silane of damage resistant coating polyurethane artificial leather.The molecular weight of silane is more than 200.Silane has in organic side chain suitably forms hydrogen bridge bond polarity group.After polyurethane artificial leather surface is protected through silane coating material, make polyurethane artificial leather that there is more preferable scratch-resistant Flaw characterization, improve the use quality of polyurethane artificial leather.
Description
Technical field
The invention belongs to polyurethane artificial leather technical field, and in particular to a kind of polyurethane artificial leather of the silane coating of damage resistant.
Background technology
Artificial leather is a kind of outward appearance, feel like leather and can replace its plastic products that use.Generally using fabric as base, coating synthetic resin and the addition of various plastics are made.Last century the eighties, expensive fur clothing cladding common people can not consume, and in response to the market demand, the artificial leather of counterfeit leather once came into vogue, and be widely used in clothing, system bag.
The silane coating of silicones production is known, by constantly development, it should which silane coating can improve the use quality of artificial leather as the protective layer of artificial leather.
The content of the invention
Polyurethane artificial leather is coated with it is an object of the invention to provide a kind of silane of damage resistant.
The present invention the used technical scheme that solves the above problems is：A kind of silane of damage resistant is coated with polyurethane artificial leather, is to cover with paint, lacquer, colour wash, etc. one layer of silane coating material in polyurethane-base basal surface and solidify, the silane coating material is to blend the silane that one or more are not pre-condensed or part is pre-condensed with reactant.
According to the present invention, the molecular weight of the silane is more than 200, more preferably greater than 300, especially greater than 500, and most preferably greater than 1000.
In scope of the invention, the silane has in organic side chain suitably forms hydrogen bridge bond polarity group.
Relatively rational set is, before the solidification, and organic cross-linking reaction is carried out by the silane of the silane and homology or non-homology or with organic monomer, oligomer or polymer.
The improvement of the present invention is that solvent is added in silane coating material, including alcohol, acetate, ether or reaction diluent.
Further, to wet-chemical silane coating coating material on polyurethane-base bottom, including spraying, dipping, flow coat, roller coat, smearing, extrusion, centrifugal coating, blade coating or vacuum evaporation.
Compared with prior art, the advantage of the invention is that：The polyurethane artificial leather being coated with there is provided a kind of silane, after the silane coating material protection by the present invention, makes polyurethane preferably damage resistant, improves the use quality of polyurethane artificial leather.
