Abstract
The invention relates to an ultraviolet light cured elastic flat lacquer and a preparation method thereof. The flat lacquer mainly comprises matrix resin, a reactive diluent, an elastic addition agent, extinction powder, a photoinitiator and a solvent. The flat lacquer has good hand feeling and excellent chemical reagent resistance, and has good matt effect, and a trial optimum formula is available. The ultraviolet light cured elastic flat lacquer also has the '5E' advantages of photocureable coating of high curing rate, low energy consumption, high efficiency, environmental friendliness and no pollution, and the like, can be used for coating automotive trim and electronic products such as cell phones and tablet personal computers, and has wide industrial application prospect.
Description
Technical field
The present invention relates to radiation curable coating technical field, be specifically related to a kind of ultraviolet curing type urethane acrylate elastic handfeel dumb light paint and preparation method thereof, this coating feel is good, elegant in appearance, can be used for automotive trim, the field of coating of electronic product.
Background technology
Along with growth in the living standard, people are also more and more higher to the requirement of quality of life.For articles for daily use, no matter, in outward appearance or sense of touch, constantly pursue brand-new, comfortable experience.Therefore the many high-grade articles for use of current era, start with attractive in appearance, comfortable profile and sense of touch, attract popular attention.Elastic handfeel paint arises at the historic moment.It is with appearance attractive in appearance, and comfortable Human physiology sense of touch, gradually in industries such as automotive trim, electronic products, gains a place, and day by day obtains more favor.But existing elastic handfeel paint is all to adopt traditional bicomponent system without exception, utilize hydroxyl and isocyano reaction to be cured, production efficiency is low, environmental pollution is serious.
The curing component that uses hydroxy component in Chinese patent application CN101921538A and contain vulcabond mixes, and has prepared and has been with coloured elastic handfeel paint.But in its curing component, with hexamethylene diisocyanate (HDI), there is very large toxicity, harmful, bring environmental pollution.And this elastomeric paint employing two-pack mixing, long reaction time, production efficiency is lower.
Also there is patent to adopt water-based system to replace organic solvent to prepare environment protection elastic coating.As Chinese patent CN102002166A has prepared a kind of polyurethane aqueous dispersion body of hydroxyl, the method preparation that it adopts self-emulsifying, has reached the requirement of environment protection.But in curing of coating process, still need to add isocyanates solidifying agent, and need at high temperature toast or normal temperature under dry for a long time, fail finally to reach the environmental requirement of " Green Chemistry ".
[prior art document]:
[patent documentation]:
[patent documentation 1]: CN101921538A
[patent documentation 2]: CN102002166A
For problem noted earlier, the present invention, in the preparation of elastic handfeel paint, has introduced UV-curing technology, and ultraviolet-curing paint has less energy-consumption, low solvent volatility, the advantages such as curing speed is fast, and production efficiency is high, coating performance excellence, can overcome the inefficiency that traditional curing brings, with serious pollution problem, the present society focusing on efficiency and quality, is subject to paying close attention to more and more widely.
The object of the invention is to prepare a kind of ultraviolet curing type urethane acrylate elastic handfeel dumb light paint, it is fast that this paint has curing speed in application, chemical reagent resistance is good, full dumb light, the advantages such as sense of touch is comfortable, can be described as photo-cured coating and elastic handfeel coating are combined, have the product of the two advantage concurrently.
Summary of the invention
In order to reach the above target, the inventor is concentrated to be studied.Found that, take ultraviolet curing type urethane acrylate as matrix resin, the auxiliary good active function monomer of chain snappiness that is equipped with, as EOEOEA, TPGDA, HDDA, TMP (3EO) EA etc., add appropriate light trigger as Irgacure184, Irgacure127, Irgacure7544, Irgacure819 etc., can be issued to good solidification effect in UV-light.Adding of dumb light powder, elastic handfeel filler, can make paint film have good dumb light effect, and good sense of touch.In performance test, find, this paint film has good chemical resistant properties (acid, alkali, alcohol, oleic acid) equally, higher hardness and the sticking power good to plastic basis material.
That is to say, according to the urethane acrylate elastic handfeel dumb light paint formulation for coating material of ultraviolet curing type of the present invention, be characterised in that and comprise:
As the urethane acrylate of the matrix resin ultraviolet curing type of film forming component, active function monomer, elastic handfeel filler, flatting silica, light trigger, solvent etc.
Ultraviolet curing type urethane acrylate elastic handfeel dumb light paint described in the present invention, its composition and mass percent are:
The preparation of ultraviolet curing type urethane acrylate elastic handfeel dumb light paint, one of them preferred version, mass percent consists of:
The preparation of ultraviolet curing type urethane acrylate elastic handfeel dumb light paint, its slurry preparation method is:
Component (a) to component (e) is weighed up and added in container by quality successively, with homogenizer, with the speed of 2000-2500r/min, tentatively mix, under in this process, add component (f) in batches, after homogeneous to be mixed, speed is adjusted to 3500-4000r/min, stir 30min, can make the ultraviolet curing type urethane acrylate elastic handfeel dumb light mill base material that can be used for application.
The preparation of ultraviolet curing type urethane acrylate elastic handfeel dumb light paint, its paint film preparation method is:
Can pass through blade coating, the methods such as spraying, are coated in gained slurry on the base materials such as ABS or PC, place 20min at 40-50 ℃ to dry, and then under UV-light, carry out photocuring, and curing energy is not less than 150mj/cm
2, film thickness is 30-60 μ m.
Described component (a) is the double bond containing ultraviolet curing type urethane acrylate of the end of the chain, the urethane acrylate of optional polyether-type, polyester type, polytetrahydrofuran type, polycarbonate type.
Described component (b) is to mix by a certain percentage gained by different functionality active function monomers such as ethoxy ethoxy ethyl propylene acid esters (EOEOEA), tripropylene glycol diacrylate (TPGDA), 1,6 hexanediol diacrylate (HDDA), ethoxyquin trimethylolpropane acrylates (TMP3EOTA), tetramethylol methane tetraacrylates (PET4A).
