A kind of ultraviolet curing type urethane acrylate elastic handfeel dumb light paint and preparation method thereof
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 excellent touch, 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, the requirement of people to quality of life is also more and more higher.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 the industry such as automotive trim, electronic product, gains a place, and day by day obtains more favor.But existing elastic handfeel paint is all adopt traditional bicomponent system without exception, utilize hydroxyl and isocyano reaction to be cured, production efficiency is low, environmental pollution is serious.
Use hydroxy component and the curing component containing vulcabond to mix in Chinese patent application CN101921538A, prepare the coloured elastic handfeel paint of band.But with hexamethylene diisocyanate (HDI) in its curing component, there is very large toxicity, harmful, bring environmental pollution.And this elastomeric paint adopts two-pack mixing, long reaction time, production efficiency is lower.
Also patent is had 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, it adopts the method for self-emulsifying to prepare, and reaches the requirement of environment protection.But still need to add isocyanates solidifying agent in curing of coating process, and need at high temperature toast or dry for a long time under normal temperature, fail finally to reach the environmental requirement of " Green Chemistry ".
