Description
Technical field
The present invention relates to a kind of high solids content uv curing coating compositions, be especially adapted for use in the anti-of plastics and wood base material
Iodine pollutes and antibacterial high solids content uv curing coating compositions.The invention still further relates to the preparation method of this coating composition,
It is for coating the purposes of base material, uses the method for its coating base material and scribbles its base material.
Background technology
Due to health, the reason such as attractive in appearance and safe, surfacing (such as floor, floor tile, carpet, plastics/stone countertops etc.)
It is used in a large number in modern production and life.Plastic plate and timber are wide variety of surfacings in modern production and life,
Such as, the floor in public as airport, station, hotel, office space, Factory Building, hospital and house etc. or private buildings or platform
Face etc..Especially, in the place that the flows of the people such as hospital, school, airport are big, generally require wear-resisting, the plastic plate of good springiness of employing
Material or timber are as elastic ground material.For meeting the multiple requirement in use of this earth material, need to use thereon
Certain functional coat.
Due to the strictest public health requirement and environmental requirement, it is desirable to the surfacing used is (such as
Floor that plastic plate and timber are made or table top) coating contain considerably less or even without organic volatile (that is, VOC), and
And need it to have chemical treatments (sterilization processing) to there is well tolerable property (that is, good chemicals-resistant corrosivity) even
Self i.e. has certain anti-microbial property.Especially since in a large amount of occasions using iodine tincture such as hospital inevitably warp
The phenomenon that iodine tincture drips often occurs, and iodine tincture is very strong to the permeability of earth material, therefore also wants to for these places
The coating of earth material has good anti-iodine contaminative.
But, the coating being currently used for plastic plate or cork often has poor wear-resisting, chemicals-resistant corrosivity, and
And typically not there is anti-microbial property.On the other hand, there is wear-resisting, the corrosive coating of chemicals-resistant and the most often have poor soft
Toughness.Additionally, the iodine that permeability is strong is seldom polluted by coating products the most on sale toleration, and most of commercialization
Coating contains volatile organic matter (VOC), and operator and environment can be caused bigger harm by this, nor meet at present
The environmental protection policy of various countries.
Therefore, one is needed to have wearability, pliability (elastic), chemicals-resistant corrosivity concurrently (as resistance to iodine pollutes all the time
Property), the performance such as antibacterial, the most again coating products for flooring material of environmental protection.
