Abstract
The invention relates to an adhesion promoter which comprises an epoxy resin, a polyurethane resin, a surfactant and diluent, wherein the polyurethane resin is polyester polyurethane, polyether polyurethane or polyester-polyether polyurethane, the surfactant is a mixture of a carbon hydrogen surfactant and a fluorine surfactant, and the diluent is an organic solvent or a mixture which is miscible with water and is composed of an organic solvent and deionized water. The invention has the following advantages: the universal and effective adhesion promoter is provided, a preparation process for the adhesion promoter is simple, and the adhesion promoter has stable quality, can substantially improve adhesion fastness of printing ink and is convenient for organization of large-scale production.
Description
Technical field
The present invention relates to a kind of promotor, especially a kind of adhesion promoter that is used for safety line production.
Background technology
Adhesion promoter is widely used in base materials such as various chemical fibres, timber, plastics, metal, pottery, glass and PVC; Increase substantially the sticking power of rete and ground, it is a kind of new type resin type adherence promotor, for the slip-off preventing property of coating special efficacy is arranged; Can improve the sticking power of multiple coating system; As: water-borne coatings, water color ink, stamp rubber cement, UV gloss oil, plastic paint, metal baking finish etc., be particularly useful for water-miscible paint, improved sticking power and toughness.
In the safety line production process; Often because the quality problems of base material film itself; Low etc. like surface irregularity, surface tension; Perhaps in preceding working procedure processing process, printing surface has been caused pollution, or the defective of printing ink itself cause the attachment fastness of printing ink on film substrate not enough, be prone to come off, decline, unstable product quality and the production that has finally caused yield rate is not smoothly even stop production.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: propose a kind of universal adhesion promoter that can significantly improve the attachment fastness of printing ink.
The technical scheme that the present invention adopted is: a kind of adhesion promoter, comprise epoxy resin, urethane resin, tensio-active agent and diluent, and their weight percent does
According to another preferred embodiment, a kind of adhesion promoter comprises that further said epoxy resin is bisphenol A-type, and molecular weight is smaller or equal to 500, and oxirane value is greater than 0.42.
According to another preferred embodiment, a kind of adhesion promoter comprises that further said urethane resin is PAUR, polyether(poly)urethane or polyester-polyether(poly)urethane, and the molecular weight average of said urethane resin is 3000～5000.
According to another preferred embodiment, a kind of adhesion promoter comprises that further said tensio-active agent is the mixture of hc-surfactant and fluorine surfactant, and the weight ratio of said hc-surfactant and fluorine surfactant is 5～50: 1.
According to another preferred embodiment, a kind of adhesion promoter further comprise said thinner be organic solvent or can with the miscible organic solvent of water and the mixture of deionized water.
According to another preferred embodiment, a kind of adhesion promoter comprises that further said organic solvent is toluene, hexanaphthene, methyl acetate, n-propyl alcohol, phenylcarbinol or their mixture.
The invention has the beneficial effects as follows: a kind of general and efficient adhesion promoter is provided, and its manufacture craft is simple, and steady quality can significantly improve the attachment fastness of printing ink, is convenient to organize large-scale production.
Embodiment
A kind of adhesion promoter comprises epoxy resin, urethane resin, tensio-active agent and diluent, and their weight percent does
Among the present invention, said epoxy resin is bisphenol A-type, and molecular weight is smaller or equal to 500, and oxirane value is greater than 0.42.This bisphenol A type epoxy resin is by dihydroxyphenyl propane, epoxy chloropropane condensation under alkaline condition, then through washing, the refining macromolecular compound that forms of desolventizing.The molecular structure of bisphenol epoxy has determined its performance characteristics: can form multiple performance excellent in curing thing with multiple solidifying agent, catalyzer and additive, this cured article has very high intensity and cohesive strength.
Among the present invention, said urethane resin is PAUR, polyether(poly)urethane or polyester-polyether(poly)urethane, and the molecular weight average of said urethane resin is 3000～5000.The content of urethane resin in adhesion promoter has very big influence to the stability of attachment fastness and ink system.The too high ink system that causes easily of content is unstable, causes resin and pigment layering; Content is too low then to be not enough to improve attachment fastness.In an embodiment of the present invention, the weight percent of urethane resin is 30～60%.
In the present invention, tensio-active agent is the mixture of hc-surfactant and fluorine surfactant, and the weight ratio of hc-surfactant and fluorine surfactant is 5～50: 1.Wherein the high surface of fluorine surfactant has determined its consumption seldom, and its high thermal stability and high unreactiveness have determined the stability of ink system and gloss are not caused negative impact.When hc-surfactant and fluorine surfactant mixing use, can reduce the surface energy of ink system, through the control add-on, can make that the substrate surface wettability is good, be convenient to drying, do not influence the effect of coating.
In adhesion promoter of the present invention, said thinner be organic solvent or can with the miscible organic solvent of water and the mixture of deionized water.The organic solvent that wherein can be used for present embodiment is toluene, hexanaphthene, methyl acetate, n-propyl alcohol, phenylcarbinol or their mixture.
Preparing method of the present invention is:
The first step mixes epoxy resin and urethane resin in proportion in diluent;
In second step, add tensio-active agent and uniform mixing.
Particularly, in this preparing method's the first step, preferably adopt middling speed to stir, in second step, preferably adopt high-speed stirring.
The invention provides a kind of general and efficient adhesion promoter, its manufacture craft is simple, and steady quality can significantly improve the attachment fastness of printing ink, is convenient to organize large-scale production.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm its technical scope according to the claim scope.
