Abstract

The invention discloses a kind of glossy leather finishing agent of ultraviolet light solidfication water polyurethane acrylate, it is mixed by following components by weight percentage：Polyalcohol 10~30%, isocyanates 10~40%, small molecule dihydroxylic alcohols 2~10% of the molecular weight below 150, hydrophilic chain extender 2~5%, chain extension modifying agent 2~5%, acrylate ended agent 3~8%, catalyst 0.01~0.1%, radical polymerization inhibitor 0.01~0.5%, nertralizer 1~3%, water-based thickener 0.5~1%, hand feeling agent 3~5%, wetting agent 0.5~1%, levelling agent 0.04~0.1%, light trigger 0.01~0.5%, deionized water surplus.The characteristics of present invention has low viscosity, environmental protection, fast curing rate, is especially suitable for use as the finishing agent of leather or artificial leather.

Description

A kind of glossy leather finishing agent of ultraviolet light solidfication water polyurethane acrylate
Technical field
The present invention relates to a kind of leather finishing agent, more particularly to a kind of ultraviolet light solidfication water polyurethane acrylate is glossy Leather finishing agent.
Background technology
An important link is exactly to cover with paint, lacquer, colour wash, etc. in the production process of leather, and the attractive in appearance of leather can be increased in this process With durable performance, the class of leather is improved, dermatine is more nearly corium.Aqueous Polyurethane Leather Finishing Agent is obtained in recent years Widely paid close attention to people, liked by people because its is pollution-free, low cost, wearability are good and stores conveniently.And water Property polyurethane be used for leather finish when, there is good good leveling property, filming performance, strong covering power and firmness.Cover with paint, lacquer, colour wash, etc. The features such as leather afterwards has bright, plentiful, wear-resisting, while having the advantages that elastic good, low temperature resistant, folding.
UV-curing technology is using light trigger under ultraviolet light, to trigger unsaturated organic monomers to be gathered The chemical reactions such as conjunction, grafting, crosslinking are so as to reach a kind of rapid emerging technology for solidifying.Due to hardening time is short, equipment Simply, capacity usage ratio is high, solidification temperature is low, it is free from environmental pollution the features such as, so it once occur receive the extensive of people Concern.
Late 1960s, Beyer Co., Ltd of West Germany develops photocuring unsaturated polyester (UP) adhesive first, ultraviolet from this The features such as light-cured resin is with its solvent-free volatilization, fast solidification rate and save energy is favored by people, is obtained in recent years Quick swift and violent development.But because esters of acrylic acid reactive diluent usual in conventional oil-based UV curing systems is to the skin of people Skin and eyes have stronger stimulation, and influence operator's is healthy；And many reactive diluents are in ultraviolet light spoke It is difficult to react completely according to during, residual monomer directly influences the long-term behaviour of cured film, also limit it in food hygiene Application in industry, and aqueous UV curing coating combines the advantage of traditional UV curing technologies and water paint technology, especially It is environmentally safe, good without influence, nonflammable, security on health, is rapidly progressed nearly ten years, and into It is a Main way of paint development.Wherein, aqueous polyurethane acrylate (WPUA) is most class of current research UV-curable waterborne system, is either still all paid much attention to by people at home abroad.Urethane acrylate There are carbamate and carboxylic ester structural units simultaneously in the macromolecular structure of photosensitive resin, it combines polyurethane and acrylic acid The premium properties of resin, while also have can easily be accommodated viscosity and rheological characteristic, environmentally safe or contaminative very little, nonhazardous And it is missing of ignition the features such as, be worth Devoting Major Efforts To Developing coating variety.
What is reported patent both at home and abroad at present is the preparation method on ultraviolet light solidfication water polyurethane resin more.Such as patent Photocuring Waterborne Polyurethane Prepolymer is prepared using in-situ method in the patent of application number 201110178207.6, acrylic acid fourth is selected Ester (BA) and tripropylene glycol double methacrylate (TPGDA) adjust soft and hard segments ratio as reactive diluent, and obtained emulsion is equal First, stabilization, with preferable mechanical property.But light-cured polyurethane double bond content prepared by the method is not very high, is caused Hardening time is more long, and gel content is not also high.The patent of application number 200610038981.4 increases double bond using reactive diluent The method of content, causes adhesive force poor, and the excitant of reactive diluent causes damage to workmen's body.
The content of the invention
It is an object of the invention to provide a kind of glossy leather finishing agent of ultraviolet light solidfication water polyurethane acrylate, tool The characteristics of having low viscosity (range of viscosities is in 20~100MPas), environmental protection, curing rate fast (10~30s can just solidify), It is especially suitable for use as the finishing agent of leather or artificial leather.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of glossy leather finishing agent of ultraviolet light solidfication water polyurethane acrylate, by weight percentage by with the following group Divide and be mixed：Polyalcohol 10~30%, isocyanates 10~40%, small molecule dihydroxylic alcohols 2 of the molecular weight below 150~ 10%, hydrophilic chain extender 2~5%, chain extension modifying agent 2~5%, acrylate ended agent 3~8%, catalyst 0.01~ 0.1%, radical polymerization inhibitor 0.01~0.5%, nertralizer 1~3%, water-based thickener 0.5~1%, hand feeling agent 3~5%, profit Humectant 0.5~1%, levelling agent 0.04~0.1%, light trigger 0.01~0.5%, deionized water surplus.
