Abstract
The invention discloses a water-based mechanical microcellular foaming paint which comprises the following components in percentage by mass: 10-95% of water-based polyurethane resin, 0.01-5% of foaming agent, 1-40% of pigment, 0-10% of packing, 0-5% of assistant and the balance of deionized water. The invention also discloses an application process of the water-based mechanical microcellular foaming paint in synthetic leather, which comprises the following steps: well stirring and dispersing the water-based polyurethane resin, the packing, the assistant and the foaming agent, and spreading the slurry on release paper on the premise of mechanically and uniformly stirring to prepare superfine fiber synthetic leather or spreading the slurry on synthetic leather to serve as a coating. The water-based mechanical microcellular foaming paint provided by the invention has the advantages that production raw materials are environment-friendly materials which are harmless to the environment, no three wastes are generated in the slurry preparation and production processes, the requirement of the current production process is met, and the economic and environment benefits are remarkable.
Description
Technical field
The present invention relates to a kind of aqueous foaming paint and application art thereof, be specifically related to a kind of water-based mechanical micro foamed coating and the application art in synthetic leather thereof.
Background technology
At present, superfine fiber chemical leather adopts solvent-borne type dry method and wet polyurethane preparation, and the salient features that solvent-borne type dry method and wet polyurethane technology can satisfy superfine fiber chemical leather fully requires and suitability for industrialized production.But solvent-borne type synthetic leather technology can cause a large amount of pollutions; It mainly is the discharging of organic solvent; Though solvent recovery unit has been arranged at present, and solvent recuperation is not thorough, and partial solvent still has no idea to reclaim; The waste residue that produces in the solvent recuperation process can cause secondary pollution, also has no idea at present to reclaim.
Summary of the invention
Goal of the invention: the present invention provides a kind of water-based mechanical micro foamed coating of environmental protection in order to solve the deficiency of prior art.
Another object of the present invention is for the application art of a kind of above-mentioned water-based mechanical micro foamed coating in synthetic leather, this art production process environmental protection are provided.
The technical scheme that the present invention adopts: a kind of water-based mechanical micro foamed coating; Comprise following component by mass percent: waterborne polyurethane resin 10-95%, whipping agent 0.01-5%, pigment 1-40%, filler 0-10% and auxiliary agent 0-5%, surplus are deionized water; Described waterborne polyurethane resin is made by aliphatic diisocyanate and aromatic diisocyanate and polyol reaction, and the molecular weight of said waterborne polyurethane resin is 20000-1000000.
As optimization, said whipping agent comprises having hydrophilic and the tensio-active agent oleophylic structure, like Stearyl Amine.
As optimization, said pigment comprises inorganic and pigment dyestuff.
As optimization, said filler comprises cerate, silicon-dioxide.
As optimization, described auxiliary agent comprises flow agent, moistened surface agent.
The application art of a kind of said water-based mechanical micro foamed coating in synthetic leather: above-mentioned waterborne polyurethane resin, filler, pigment, auxiliary agent and whipping agent dispersed with stirring is good; Under the prerequisite that machinery evenly stirs, slurry is coated in and prepares superfine fiber chemical leather on the separate-type paper, perhaps slurry is coated in and does coating on the superfine fiber chemical leather.
Beneficial effect: the present invention has adopted environment-friendly aqueous polymeric coating material; The superfine fiber chemical leather good hand feeling that the little intumescent coating of cooperative mechanical technology is produced, soft flexible, ventilation property and water absorbability are better, comfortable and easy to wear; The outward appearance that is rich in natural leather is fit to produce all kinds of high-end leatherware.The raw materials for production of water-based mechanical micro foamed coating of the present invention all are the environment-friendly materials of environmental sound, and pulp preparation and production process all do not produce the three wastes, satisfy present production technique, economic benefit and obvious environment benefit.
