Description
Technical field
The present invention relates to radiation curing technology field and paint field, particularly UV radiation curable adhesive and preparation method thereof.
Background technology
The sixties in last century, Germany has released the green technology of first-generation UV coating, in the industrial Preliminary Applications that obtains of woodwork coating.Later on radiation curing technology progressively extends to paper, various plastics, metal, stone material by the single base material of timber, even the application of base materials such as cement products, fabric, leather is used.
Radiation curing (UV/EB curing) is actually a kind of and realizes that by means of energy exposure source (ultraviolet ray or electron beam) chemical formulation (coating, printing ink and tackiness agent) is converted into the solid-state course of processing by liquid state.Compare with traditional curing technology, radiation curing technology have environmental protection, energy-conservation, curing speed is fast, advantage such as easy and simple to handle, has obtained fast development in recent ten years.The uv radiation curing technology does not contain solvent usually, and surrounding environment non-volatility organism (VOC) is produced, and the epoch that adapted to " decontamination, protection environment " call, thereby radiation curing technology more and more is subject to people's attention.
Quantity of radiant energy such as radiation curable coating is in utilizing, shortwave (300-400 nanometer) UV light or EB cause the macromolecular material (resin) that contains active function groups and aggregate into the coating variety that insoluble molten solid is filmed.
The material of radiation curable coating is formed:
1. oligopolymer, also claim oligopolymer or oligomer, low viscosity contains the synthetic resins of active function groups, it is the basic framework in the UV coating, under the effect of ultraviolet photon, form the paint film with three-dimensional arrangement, and give the various characteristics of paint film, for example hardness, snappiness, sticking power, gloss, performance such as ageing-resistant.Comprise: acrylic acid epoxy resin, acrylic acid polyester resin, acrylic polyether resin, vinylformic acid Synolac, acrylated polyurethane resin, acrylic-amino resin, unsaturated polyester resin, Resins, epoxy etc.
2. reactive thinner, main effect are the solid ingredients in the dissolving U V coating, regulation system viscosity.Thinner in the UV coating is not the volatile organic solvent that general coating uses, but participates in the non-volatility solvent that the film-forming process has response capacity directly.Reactive thinner generally is that molecular weight is little and intramolecularly contains a class monomer of polymerizable functional group with regard to chemical structure, becomes the part of paint film after the film forming.Comprise: Acrylic Acid Monomer, styrene monomer.
3.UV the luminous energy initiator is the key components in the UV coating, its role is to transmit the energy of ultraviolet photon, the crosslinking polymerization of rapid trigger monomer and oligopolymer, the liquid-solid switching process of promotion system.According to triggering mechanism, light trigger can be divided into free radical and positively charged ion two major types.Comprise: st-yrax ethers, benzophenone derivates, benzil ketals, ketoamine mixture etc.
4. auxiliary agent for satisfying concrete service requirements, improving some complementary component that paint film property is added, comprising: defoamer, flow agent, stablizer, dispersion agent etc.
The initiator system that radiation curing technology is used according to its curing mechanism, mainly contains two kinds of free radical type curing system and cationic curing systems.
Curing system for free radical type is characterized in: curing speed is fast, and the initiator type of free radical type is also more, and is comparatively deep to its research, and correlation theory is comparatively ripe; Shortcoming is: the volumetric shrinkage during curing is bigger, cause producing in the glue-line after curing very big internal stress, had a strong impact on tackiness agent bonding to base material, and the curing system of free radical type, the oxygen inhibition phenomenon is more serious, the deep layer position can't be solidified, for those ultraviolet radiations less than the dead angle, then can not solidify fully.
For cationic curing system, its characteristics: volumetric shrinkage is little after solidifying, and can not produce very big internal stress, strong adhesion, and the problem that does not have oxygen inhibition in the solidification process, for darker position or ultraviolet radiation less than the position, can effectively be cured.Shortcoming is: the initiator type that this system can be selected for use is less, and people are also very shallow for the research of this system, and curing speed differs bigger than the initiator system of free radical type.
In recent years, at the different characteristics of free radical type initiator system and cationic initiator system, the composite of free radical type initiator system and cationic initiator system appearred.But in general, effect also is not desirable especially.Contraction when solidifying as system is still bigger, thereby has brought uncertain internal stress to exist, and this can play bad counter productive to the cementability of tackiness agent.And the weather resistance of this compound system neither be very desirable, find especially in actual applications, and bonding material, through the weather-proof after date in 1 to 2 year, strength degradation was bigger, even the appearance of the phenomenons such as infiltration of cracking, tomography, water occurred.
Summary of the invention
Technical barrier to be solved by this invention is: there are problems such as uncertain internal stress, poor durability in the tackiness agent at present existing radiation curing free radical/positively charged ion compound system; The invention provides a kind of radiation curing free radical type and the composite tackiness agent of cationic initiator system, show excellent bonding strength and weathering resistance (being primarily aimed at high low temperature, humidity), can be widely used in the bonding of glass, iron, stainless steel, aluminium, pottery, stone material etc., have good bonding intensity and weather resistance.
The preparation method of the radiation curable adhesive that the free radical type with good bonding intensity and weather resistance that the another technical barrier that will solve of the present invention is to provide above-mentioned and cationic initiator system are composite, the particularly preparation method of the acrylate superpolymer that wherein adds.
