Abstract
Semi-aromatic polyamide artificial leather is coated with the present invention relates to a kind of silane of anti-finger mark, it is to cover with paint, lacquer, colour wash, etc. one layer of silane coating material in semi-aromatic polyamide substrate 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 molecular weight of silane is more than 200.Silane has in organic side chain suitably forms hydrogen bridge bond polarity group.After semi-aromatic polyamide artificial leather surface is protected through silane coating material, make semi-aromatic polyamide artificial leather that there is more preferable anti-finger mark characteristic, improve the use quality of semi-aromatic polyamide artificial leather.
Description
Technical field
The invention belongs to semi-aromatic polyamide technical field of artificial leather, and in particular to a kind of semi-aromatic polyamide artificial leather of the silane coating of anti-finger mark.
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
Semi-aromatic polyamide artificial leather is coated with it is an object of the invention to provide a kind of silane of anti-finger mark.
The present invention the used technical scheme that solves the above problems is:A kind of silane coating semi-aromatic polyamide artificial leather of anti-finger mark, it is to cover with paint, lacquer, colour wash, etc. one layer of silane coating material in semi-aromatic polyamide substrate surface and solidify, the silane coating material is that the silane that one or more are not pre-condensed or part is pre-condensed is blended with reactant, and wax is included in silane coating material.
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 in semi-aromatic polyamide substrate, 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 semi-aromatic polyamide artificial leather being coated with there is provided a kind of silane, after the silane coating material protection by the present invention, makes the preferably anti-finger mark characteristic of semi-aromatic polyamide, improves the use quality of semi-aromatic polyamide artificial leather.
