Prior art
In furniture and wood industry, known use priming paint or sealing agent, such as with acrylic based lacquers form, pre-treatment is carried out to the edge of plank and surface, described plank is solid wood board, glued board or porous plate such as, such as shaving board or MDF plate (MDF=medium-density plate) and the plate be made up of rock wool and gypsum.Described pre-treatment is to form the flat surface that has good adhesion, for possible follow-up polished finish.
After applying such as the first layer paint, described plate can use the polishing such as sand paper, sander usually, then processes and polishes and can be repeated one or more times.After completing process, the coating, varnish etc. of one or more end layer can be applied on pretreated surface.In addition, described surface and/or edge paper using, veneer sheet, ABS plastic, gold stamping or similar surfaces can be coated with and obtain production board.Then the plate after process can be further processed into the goods such as furniture, desktop, floor.
In preprocessing process, the aperture at porous surface and edge is filled up by varnish, and varnish is subsequently by the such as solidification under ultraviolet (UV) line irradiates of usually known curing.
The example processing the system of porous plate and solid wood board particular edge with varnish (in advance) can find in WO99/51361A1.
For the known varnish of pre-treatment porous plate particularly including UV solidified paint, but, they have relatively costly defect, this means the initial surface treatment at surface and edge, particularly to porous plate, constitute the major part relatively of finished product production prices, because the varnish that the cavity at porous surface and edge is expensive in preprocessing process fills up.
The known glass particle that uses in surface treatment agent imparts surface treatment agent UV absorptive character, see US2005/0147571A1, and obtains scratch resistant surface, see EP1319524A1.But whether these documents add to have maybe may have in importance to the solidification process of certain UV curable resin composition all do not illustrate glass particles.
Goal of the invention
The present invention wants to provide a kind of fluid surface treatment agent, comprise such as UV curing acrylic base paint, owing to using cheap filler, production cost is lower, therefore it is in use more cheap than known acrylic based lacquers, and it is also friendly to environment and Working environment, and can not cause environmental problem, therefore, when the product after surface treatment will be processed or destroy after being finished, stricter requirement is being had as in dangerous waste material process.Finally, desirable to provide a kind of surface treatment agent, it has lower energy cost aborning, and it reduces CO relative to known surface treatment agent 2contribution, or be not at least significantly increased contribution.
The realization of this object is that surface treatment agent as claimed in claim 1 contains film forming material and filler.Especially, suitable filler comprises and is selected from inorganic salt or is just called salt, chalk (CaCO 3), the particulate material of glass, plastics, wood powder or these one or more combination.Particularly about salt, chalk and wood powder, these fillers are eco-friendly, are also cheap products.
Described filler should cover pending surface to make film forming material (containing acrylic acid resin in UV curing acrylic base paint) but the amount of the sticking power and/or hiding power that do not affect surface treatment agent is added.So just, the surface treatment agent usage quantity of every square metre of treat surface can be reduced, also comprise expensive UV solidified paint, achieve more cheap process of surface treatment.And have been found that the interpolation of filler makes the wearing and tearing of aftertreatment instrument and grinding apparatus reduce.
As claimed in claim 2, the favourable amount of described granular filler is the 10-85%, particularly 25-80% of surface treatment agent total amount, most preferably 40-75% (volume %).This achieve good " dilution " of Film forming resin compositions in surface treatment agent, thus achieve the reduction greatly of every square metre of treat surface price, and surface-treated quality does not have Packed relatively costly UV solidified paint obviously not reduce relative to use.
