Abstract
The invention discloses an open type aqueous UV shower-coating clear primer. The open type aqueous UV shower-coating clear primer comprises the following raw materials in percentage by weight: 45%-60% of a PUA aqueous dispersion 1, 15%-30% of a PUA aqueous dispersion 2, 0.5%-1% of a defoaming agent, 0.1%-0.5% of a wetting agent, 1%-5% of a cosolvent, 1%-3% of a photoinitiator, 15%-20% of de-ionized water and 0.1%-0.5% of a multifunctional aid. The open type aqueous UV shower-coating clear primer has the beneficial effects that the utilization rate can reach 100%, and the production speed and the production efficiency are high; a coating is good in defoaming property and high in hole penetration property, and a paint film is smooth and has no defect.
Description
Technical field
The invention belongs to paint field, be specifically related to the open clear priming paint of a kind of water-based UV showering.
Background technology
Solvent wood coatings contains a large amount of objectionable impuritiess, serious environment pollution, and infringement HUMAN HEALTH, wastes resource greatly.Photo-cured coating is a kind of environment-friendly type coating developed by Bayer A.G for 20 end of the centurys, China carries out photocuring research and development from the eighties in 20th century, in recent years, along with the enhancing of people's energy-conserving and environment-protective consciousness, photo-cured coating performance improves constantly, Application Areas is constantly expanded, and output increases fast, presents the impetus of fast development.One of advantage of photo-cured coating is that it is not containing solvent, thus greatly eliminate organic volatile (VOC) to the pollution of environment, but, because main component used and oligopolymer generally all have higher viscosity, reactive thinner must be added become to regulate its viscosity and stream when being coated with, and facilitate film and solidification, improve curing performance.The reactive thinner eyes added have stronger hormesis, and skin contact too much also easily causes allergy, affect the healthy of operator.In addition, many reactive monomers are difficult to complete reaction in ultraviolet light irradiation process, and residual monomer plays the side effects such as plasticising, and has permeability, affect the long-term behaviour of cured film.Meanwhile, water-borne coatings is one of Main way becoming paint development, and feature is environmentally safe, on HUMAN HEALTH without impact, nonflammable, and security is good.Under this overall situation, waterborne UV coating arises at the historic moment, relative to oiliness UV coating, beyond the advantage with water-borne coatings, water-based UV is coating material solidified does not use reactive thinner substantially, avoid the cure shrinkage and toxicity that are caused by it, high rigidity and snappiness can be taken into account simultaneously, and solidification is not by oxygen inhibition in air.These advantages become the new direction of the coating material solidified development of UV.But waterborne UV coating also has the deficiency of self, compared with oiliness UV coating, because waterborne UV coating dispersion is admittedly containing low, be difficult to the coating making high fullness ratio.
Open application, refers to a kind of application mode of exposed timber conduit.Multiselect larger, the deep timber of the texture such as Cortex Fraxini mandshuricae, oak.The lines such as rough for timber pore, pinhole can be displayed after application, this effect reasonablely can represent the texture texture of timber, gives natural sensation.The coating type that can do open system application has a lot, such as PU, NC, standard aqueous wood lacquer etc.NC open system is effective, but VOC content is large, and film bad mechanical property, in recent years, along with the reinforcement of environmental protection strength, belong to the product eliminated gradually.Conventional aqueous woodware paint requires high to drying, and mechanical property is poor, performance is difficult to match in excellence or beauty with PU coating.Current Application comparison is the open painting design of PU widely, and paint film is open effective, and hardness, sticking power, wear resistance is good.Water-based UV system is relative to PU system, and film over-all properties is obviously better than PU, and duration of service is long, and packing speed is fast, and VOC content is extremely low.It is a kind of green open painting design.
Although showering application restricted application, is only suitable for dull and stereotyped application, its paint utilization rate can reach 100%, and production rate is fast, and production efficiency is high.The author is intended to open for water-based UV system paint film effective, and production efficiency is high, and high-level efficiency and the high utilization rate of the good feature of paint film property and showering application combine, the clear priming paint of water-based UV showering opening of a development excellent performance.
