The invention provides an ultraviolet curing adhesive which consists of matrix resin, a diluent, a photoinitiator and other auxiliaries, and has the advantages of low surface viscosity after curing, good mechanical property and the like, and has wide application range and higher use value.
Description
Technical Field
The invention belongs to the technical field of photocuring materials, and particularly relates to an ultraviolet curing adhesive with low surface viscosity and a preparation method thereof.
Background
The UV curing adhesive consists of a prepolymer, an active monomer, a photoinitiator and other main components, and is matched with a stabilizer, a leveling agent and other auxiliary agents. Under the irradiation of UV light with proper wavelength, the photoinitiator can quickly generate free radicals or ions to initiate the polymerization and crosslinking of the prepolymer and the active monomer into a net structure, so as to complete the bonding with the bonded material.
The free radical type UV photocuring technology is applied earliest and mature, is a main system applied at present, has the advantages of high curing speed, economy, environmental protection, excellent film coating performance and the like, and is widely applied to the fields of coatings, printing inks, adhesives and the like. However, the coating film has the problems of oxygen inhibition due to high free radical activity and easy oxidation, so that the surface of the coating film is sticky, and the performances of the coating film such as hardness, glossiness, wear resistance and the like are affected. This therefore limits the range of applications for free radical UV cured UV glues.
Aiming at the phenomenon, a great deal of research is also carried out by broad scholars, and the research mainly comprises the following two aspects: on one hand, oxygen is isolated, namely UV curing is carried out in inert gas, or a component capable of absorbing oxygen is added, and oxygen on the surface is consumed during UV curing; on the other hand, special photoinitiator is used, such as an initiator system which can eliminate the polymerization inhibition of oxygen in the adhesive film to free radical polymerization reaction and is matched with benzophenone and tertiary amine.

Further defined, the photoinitiator is a free radical photoinitiator, and the free radical photoinitiator comprises one or two of a cracking type free radical initiator and a hydrogen abstraction type free radical photoinitiator which are mixed in any proportion.
Further defined, the cleavage-type radical initiator includes 1-hydroxycyclohexyl phenyl ketone, 2-hydroxy-4- (2-hydroxyethoxy) -2-methyl propiophenone, benzil dimethyl ether, 2-methyl-1- (4-methylthiophenyl) -2-morpholine-1-one, 2-benzyl-2-dimethylamine-1- (4-morpholine benzyl phenyl) butanone, 2-hydroxy-2-methyl-1-phenyl-1-propanone, phenyl bis (2, 4, 6-trimethylbenzoyl) phosphine oxide, 2, 4, 6-trimethylbenzoyl diphenoxyphosphine, methyl benzoylformate.
Further defined, the hydrogen abstraction-type radical photoinitiator includes benzophenone and 2-isopropyl thioxanthone.
The invention also provides a preparation method of the ultraviolet curing adhesive, which comprises the steps of mixing and stirring the base resin, the diluent, the photoinitiator and other auxiliaries at room temperature according to a proportion, and uniformly stirring to obtain the ultraviolet curing adhesive.
Preferably, the stirring speed and the stirring time are determined according to whether the stirring is complete or not.
Preferably, the stirring is complete when the system does not contain undissolved photoinitiator powder and does not contain an unstirred homogeneous matrix resin.
In the present invention, the matrix resin can provide key properties of viscosity, shear strength, hardness, flexibility, etc. of the UV glue layer, and the amount thereof is preferably 20% to 85%, and more preferably 40% to 70%. In the invention, the content of the matrix resin in the range can better prepare the UV adhesive, so that the adhesive has better and stable performance. When the content of the matrix resin is too low, the performance of the glue is affected, and when the content of the matrix resin is too high, the viscosity of the glue is higher, and the use of the glue is affected.
In the invention, the diluent is mainly used for diluting the matrix resin to a certain degree, and can be used singly or in combination of a plurality of types; in the present invention, the content of the diluent is 10% to 68%, more preferably 30% to 60%.

The cross-linking agent with an active amine structure is introduced into the system, so that the phenomenon of oxygen inhibition is inhibited, the phenomenon of surface adhesion of the cured adhesive coating is improved, and the mechanical property of the adhesive layer is enhanced.
The invention has the beneficial effects that:
in the invention, because the cross-linking agent containing an active ammonia structure is added into the system, the alpha-position hydrogen of the active amine is very active, amino free radicals are easily formed in the system, and the amino free radicals can react with oxygen, so most of the oxygen consumed during photocuring can weaken the inhibition effect of the oxygen on curing. On the basis, the adhesive tape also contains double bonds capable of performing crosslinking reaction with acrylate groups in the system, and the crosslinking reaction can improve the tensile strength, hardness, water resistance, salt water resistance, acid and alkali resistance and other properties of the cured adhesive tape, so that the phenomenon that the surface of the prepared adhesive tape is sticky after UV curing is improved, the mechanical property of the adhesive layer after UV curing is enhanced, the application range is expanded, and the use value is improved.
