Abstract
The invention relates to UV solidified generality laminated adhesive suitable for the thin film spraying technology. The UV solidified generality laminated adhesive comprises, by weight, 0-40 parts of (methyl) acrylate resin, 30-70 parts of (methyl) acrylic acid reactive diluents, 0-10 parts of photoinitiator and 0-5 parts of others. Compared with common UV adhesive with low viscosity, the UV solidified generality laminated adhesive has the advantages of being good in protective performance and resistant to high temperature and humidity, salt mist and cold-hot impact; compared with common UV adhesive with the good protective performance, the UV solidified generality laminated adhesive is low in viscosity, suitable for the thin-film spraying technology and capable of greatly improving the spraying efficiency; compared with the common UV adhesive with the low viscosity, the UV solidified generality laminated adhesive has the advantages of being low in surface-drying energy and rapid in solidification.
Description
Technical field
The present invention relates to polymeric material field, relate to particularly a kind of UV curing overlay film glue, meet the thin film coatings glue-applying technique.
Background technology
Thin film coated is a kind of important Modern Surface Engineering Technology.The chemical composition of coat, weave construction can be identical with body material.Coated film thickness is very little and dimension precision requirement is very high, can play the effect of three aspects: optimizing surface performance, meticulous microfabrication and produce new functional materials.Film is employed and a plurality of fields, as aviation field, ship inspection protection field, machinery industry, power industry and bridge construction.The security that the application of paint-on technique in engineering is produced improved quality and the engineering of product, reduced unnecessary loss of life and personal injury, brought very large economic benefit.Concrete paint-on technique has plating, sprays paint, thermospray and gas phase deposition technology etc.
The glue-applying technique of traditional conformal coating has brushing, compressed air spraying, dip-coating, thin film coatings, wherein most effective with thin film coatings, more and more is subject to the attention of producer.
Thin film coated technique forms the surface-coated material a kind of film of controlled, homogeneous, rather than spraying.Material is pushed out Glue dripping head and some glue nozzle under the low pressure state, and material just was attached on circuit card before reaching atomization point.Therefore it can reach the colloid transfer efficiency more than 99%, and material use efficiency has been improved to 30-50 percentage point.It can be within the several seconds circuit card of Selective coating complexity.Because coating material does not reach atomizing state, but Accurate Points glue arrives specific region, and crossing spray, mask and doing over again of often occurring in the conventional surface coating processes all controls to minimum level, eliminates even fully.This new thin film coated technique response is faster, and repeatability is higher, and life-span while is also longer, easy to clean, more environmental protection.
But it has strict demand to conformal coating water viscosity thin film coatings technique, on the low side favourable with viscosity, but reduce glue viscosity, can to damage the conformal coating protective value be cost.Simultaneously, low viscosity UV solidified glue, its surface drying energy generally can be larger, how to guarantee protective value, fast setting (surface drying energy≤1000mJ/cm
2) prerequisite under, make it to meet thin film coatings technique, the performance of conformal coating water has been proposed to more harsh requirement.Conformal coating requires after the severe condition such as high-temp resisting high-humidity resisting test, salt spray resistance test, cold-hot Impact Test are aging, and its protective value is also very excellent.
Summary of the invention
The purpose of this invention is to provide a kind of protective value solvent-free UV excellent, that be applicable to thin film coatings technique and solidify conformal coating.
For thought purpose of the present invention, following technical scheme is proposed:
A kind of UV of applicable thin film coatings technique solidifies conformal coating, and it is composed as follows by weight that described UV solidifies conformal coating:
0～40 part of (methyl) acrylate resin;
30～70 parts of (methyl) vinylformic acid reactive thinners;
0～10 part of light trigger;
Other 0～5 part.
Described (methyl) acrylate resin is epoxy (methyl) acrylate, urethane (methyl) acrylate, polyester (methyl) acrylate or polyethers (methyl) acrylate and a kind of and several mixture of modifier thereof, the more preferably mixture of urethane (methyl) acrylate.
Described (methyl) vinylformic acid reactive thinner is triglycerin two (methyl) acrylate, ethoxyquin triglycerin two (methyl) acrylate, tetrahydrofuran (THF) (methyl) acrylate, 1, the mixture of one or more in 6-hexylene glycol two (methyl) acrylate, the third oxidation glycerol triacrylate, (methyl) isobornyl acrylate, (methyl) acrylic silicon ester, (methyl) vinylformic acid Bian ester, 2-phenoxy group ethyl (methyl) acrylate.
Described light trigger is 2-hydroxy-methyl phenyl-propane-1-ketone, 1-hydroxy-cyclohexyl phenyl ketone, 2-methyl isophthalic acid-(4-methylthio group phenyl)-2-morpholinyl-1-acetone, benzoin dimethylether, benzophenone, contraposition N, the different monooctyl ester of N-dimethylaminobenzoic acid, 2; 4; 6-trimethylbenzoyl-diphenyl phosphine oxide, 2; the mixture of one or more in 4,6-trimethylbenzoyl phenyl-phosphonic acid ethyl ester, the macromolecular cpd that is derived by above-mentioned light trigger.
Described other additives are one or more the mixture in pigment, defoamer, flow agent, wetting agent, dispersion agent.
The beneficial effect that this patent is compared with conventional art:
