Abstract
The present invention discloses a single-coating aquosity synthetic leather finishing agent. It is made up by using synthetics of modifier vinyl acetate-ehylene copolymer and existent water film-forming agent as main film-forming material and adding pigment and assistant. It uses water as dispersion medium and diluting agent, can be used for finishing leather for replacing primer, middle coating, top coating and fixing layer finishing, and integrates leather-priming, colour-forming, lustering and hand touch effect, etc. into one body to make finished leather soft and possess good gloss, high wear-resistance and water-proofing property. Compared with existent technique, it can simplify leather-finishing technology, save labour, save time, and reduce the cost of finished leather.
Description
The present invention relates to a kind of hide finishes, particularly a kind of single coating water synthetic leather finishing agent.
Covering with paint is the finishing operation of process hides, its purpose is to give the finished product leather specious, hand feel and drape, improve the physical properties of finished product leather, comprise wear resistance, water resisting property and flexible resistance, make it more durable in use, easier cleaning and maintenance can hide the permanent disability of leather by covering with paint, lacquer, colour wash, etc. technology, and step-down level skin is high-grade skin.The leather in modern age requires: coatings is light, thin, grain is clear, and maintenance kishke feel and good ventilation property, also require to film to have good physicals simultaneously, as solvent resistance, washing fastness, resistivity against fire, wear resistance, scratch resistance and antifog property, good finishing agent and coating technology have just been required.
Traditional leather finish divides undercoat, coat of colo(u)r (middle level) and top layer (bright layer), immovable bed (feel layer) multilayer to cover with paint, lacquer, colour wash, etc., each layer is covered with paint, lacquer, colour wash, etc. needs spraying one to three time, every all over all drying, complex process, the expense of taking a lot of work material, and the strong impulse smell is arranged, and poisonous, particularly some floating coats and top coat finishing agent also need in covering with paint factory composite, owing to the reason of finishing agent compounded technology and coating technology often causes coating effect very different, coated and sold high price, be coated with to have differed from and sell at a low price.Existing finishing agent generally is made up of membrane-forming agent, tinting material, auxiliary agent and medium, as shown in Figure 1.
What above coating and decorating material played a major role in finishing agent is membrane-forming agent, but it respectively has relative merits.Therefore, traditional covering with paint technology, with its be prepared into be applicable to primary coat, in be coated with, push up the finishing agent of covering with paint, in the hope of obtaining comprehensive good effect.
Abroad, some companies have released and have only used undercoat and top coat, can reach the finishing agent of coating effect.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of single coating water synthetic leather finishing agent is provided.
Single coating water synthetic leather finishing agent provided by the present invention, it is that synthetics with vinyl-acetic ester-ethylene copolymer and existing waterborne film-forming agent is main film forming matter, adds pigment and auxiliary agent makes, and is dispersion medium and thinner with water.
Above-mentioned hide finishes, its used waterborne film-forming agent can be an acrylic acid esters co-polymer, each component material consumption: (weight unit is identical)
Vinyl-acetic ester-ethylene copolymer 10～40
Acrylic acid esters co-polymer 10～40
Pigment 10～30
Auxiliary agent 10～25
Water 80～375.
Single coating water synthetic leather finishing agent provided by the present invention, it is the modifying agent of waterborne film-forming thing with vinyl-acetic ester-ethylene copolymer, thereby improved the physicochemical property of hide finishes, be used for leather finish, can replace undercoat, floating coat, top coat and immovable bed covers with paint, lacquer, colour wash, etc., it is multi-functional to integrate leather bottoming, quality glazing and handle effect, and finished leather softness, good luster, wear resisting property is good, water-repellancy is strong.Compared with prior art: simplified leather finish technology, saving of work and time, reduction finished leather cost, and coating technology is easily grasped, coating quality stable, and smell is little and nontoxic, can be made into light, inferior light, half-light, filling is arranged, do not have the series product of suitable leather requirements such as filling.
The present invention is described in further detail below in conjunction with example:
The embodiment of the invention provides a kind of single coating water synthetic leather finishing agent, it is that synthetics with vinyl-acetic ester-ethylene copolymer and methacrylic ester-styrol copolymer is main film forming matter, adds pigment and auxiliary agent makes, with water is dispersion medium and thinner, auxiliary agent is triphenylphosphate, alcohol and ethyl glycol, each component material consumption: (weight unit is identical)
Vinyl-acetic ester-ethylene copolymer 10
Methacrylic ester-styrol copolymer 40
Pigment 30
Triphenylphosphate 0.5
Alcohol 15
Ethyl glycol 4
Water 100.
