Description

A kind of flexible composite veneer and processing method thereof
Technical field
The present invention relates to a kind of band paint film or the flexible compound decorative veneer of band paint film and processing method thereof, belong to In wood working industry, it is decoration finishing, woodwork, furniture, door and window curved surface or plane surface decoration neck A kind of new technology employed in territory.
Background technology
Timber has good native texture and color and luster, gives fresh and clean sensation, therefore suffers from more Carry out the favor of the most people.
Scarcity along with precious timber resource and the continuous research to woodwork processing technique, veneer material exists Indoor furniture finishing, woodwork manufacture, if the edge sealing of wood furniture, door and window, lines and cabinet etc. is with bent Face or plane facing use more and more.
At present in woodwork and the curved surface of furniture finishing, right-angle surface part veneer, generally use back side patch There is the decorative veneer (without covering with paint, lacquer, colour wash, etc.) of non-woven fabrics or backing paper, to avoid producing wood grain cracking, rupturing and become Shape problem.But non-woven fabrics is with oil as raw material, it is difficult to degradable, and veneer with non-woven fabric compounded often Use all kinds of adhesive, environmental protection relatively not;Simultaneously as veneer is relatively thin, in manufacturing process Easily produce strike-through phenomenon, and along with illumination, the impact of temperature and humidity change, be easily generated veneer and nothing Spin cloth, veneer and the stripping of backing paper, have impact on the decorative effect of its surface veneer, substantially reduce wood The service life of skin veneering products, and its resistance to water is poor;It addition, it is thin without the non-woven fabrics decoration covered with paint, lacquer, colour wash, etc. Wood veneer after cover with paint, lacquer, colour wash, etc. again, its japanning, be dried and bruting process the most relative complex, production efficiency is low.
Summary of the invention
In view of above-mentioned problems of the prior art, it is an object of the invention to provide a kind of flexible compound Veneer and processing method thereof, it is to avoid traditional non-woven cloth decorative veneer easily occurs in processing and during using Seep through problem, it is ensured that the attractive in appearance and quality of decorative veneer;Can be directly used for curved surface and right angle cladding, subtract The complicated technologies such as few japanning, dry, polishing.
A kind of flexible composite veneer of the present invention and processing method thereof, including techniques below scheme:
A kind of band paint film flexible composite veneer, including decorative veneer layer, plastic film layers and skin of paint, moulds Material thin layer is compound on decorative veneer by heating pressurization, then is coated with last layer on compound decorative veneer surface Common paint or elastic paint;Described decorative veneer layer be 0.06~0.3mm thick natural finiss veneer or Recombinant decorative veneer, it is possible to for being modified the decorative veneer of process;Described plastic film layers be treated or Untreated polyethylene, polypropylene or other materials plastic sheeting, thickness is 0.02~0.5mm;Described oil Enamelled coating is (face) paint at the bottom of (face) paint at the bottom of (face) paint, ultraviolet light polymerization at the bottom of polyurethane or nitro etc..
Preferred as such scheme, described decorative veneer layer is that 0.06~0.3mm thick natural finiss is thin Wood or recombinant decorative veneer, it is possible to for the decorative veneer of the modifications such as softened, carbonization.Described dress Decorations veneer layer and plastic film layers compound tense, can be added to silane coupling agent, maleic acid anhydride coupling agent With all kinds of coupling agents such as polyurethanes coupling agents.Described coupling agent, can be applied to decorative veneer, or plastics Thin film.Also coupling agent or additive etc. can be added in plastic granulating, through extrusion molding and polyethylene, polypropylene Etc. making plastic sheeting.
It is a further object to provide a kind of band paint film or the flexible composite veneer of band paint film and add Work method.
A kind of band paint film flexible composite veneer and processing method thereof, comprise the following steps:
A) wood-planing is cut into the decorative veneer of 0.06mm~0.3mm;B) idol it is coated with on a plastic film Connection agent (can not also be coated with as required), coupling agent coating weight is the 1%~20% of plastic sheeting, then Display 1~20min;C) decoration being compound in advance described in step b by the decorative veneer described in step a is thin Form composite plate blanks on film, then add Antisticking (film), bottom surface respectively on the upper and lower surface of composite plate blanks Pading plate or industrial felt, play buffering, levelling effect;D) described composite plate blanks is carried out hot pressing, heat Pressure temperature 100~180 DEG C, hot pressing pressure 0.1~1.0MP, hot pressing time 1~6 minutes, in hot pressing The lowest rear high sublevel heat pressing process of pressure can be used;E) by the Antisticking (film) with compound good decorative veneer Send into oil paint production line, use on flexible compound decorative veneer surface spraying, roll coating model to varnish with lacquer, Through one or multi-channel japanning, being dried, it is thin that sanding step makes satisfactory band paint film flexible compound decoration Wood.
Preferred as technique scheme, step c), d) in can to upper lower bolster simultaneously or different time Pressurization, and the phenomenon easily crimped in order to avoid plastic foil compound decorative veneer, the both sides pressurization of upper lower bolster Temperature can be different.
Preferred as technique scheme, the pressed temperature in step d) is 125 DEG C~165 DEG C, time Between be 60~150s, pressure is 0.6~1.0Mpa.
Preferred as technique scheme, after avoiding plastic sheeting compound decorative veneer, flexible decorative The phenomenon that veneer easily crimps, the antiadhesion barrier in step d) can be selected for polyfluortetraethylene plate, can after step d) Directly carry out paint finishing by sending into painted line with the polyfluortetraethylene plate of flexible compound decorative veneer, right Relatively thin poly tetrafluoroethylene, can be at its back adhesive MDF.
Preferred as technique scheme, also includes dyestripping step, described dyestripping after step e) Step is to be torn it down from Antisticking by the compound decorative veneer through hot pressing, is rolled into a roll for veneer.
Present invention have the advantage that
1) than existing patch non-woven fabrics veneer, patch backing paper veneer, it is not necessary to add adhesive bonding, The feature of environmental protection is good, operating procedure is simple, be difficult to craze and transfiguration, good waterproof performance, it is to avoid fill in production process Decorations veneer and the seep through problem of non-woven fabrics, it is ensured that the attractive in appearance and quality of decorative veneer;
2) substantially increase water resistance and the flexility of decorative veneer, improve production environment and product The feature of environmental protection, can be directly used for curved surface and right angle cladding, decrease wood tegument veener goods in process of production Japanning, be dried, the technique such as polishing;
3) greatly improve production efficiency, saved production cost, it is ensured that product quality, have very Good application prospect.
