Description
Technical field
The invention belongs to wood processing fields, and in particular to a kind of antibacterial large format spelling is wide to impregnate decorative veneer and its manufacture
Method.
Technical background
Reform and opening-up is over 30 years, and China's economic high speed soars, and real estate expands rapidly, has driven wood-based plate, floor, family
The Linking Development of the house ornamentations and woodwork materials industry such as tool.Currently, in addition to house ornamentation, solid wooden compound floor and a small amount of furniture are using thin
Outside the wooden veneer, laminated flooring and a large amount of plate fitments are all made of melamino-formaldehyde (MF) Tetefol veneer, therefore fill
Decorations veneer has a vast market space.It is decorative faced using veneer progress, when especially carrying out veneer to artificial board substrate, still
There are some technical difficulties.
Such as：It is closed since surface layer preciousness veneer thickness is small only with paint film in solid wooden compound floor field, product
Wear-resisting and scratch-resistant performance is still insufficient；According to current process, on substrate or veneer after gluing, then hot pressing or cold is carried out
Pressure is easy to generate sheet deformation after veneer, the problems such as veneer is bubbled or seep through.Meanwhile the width of veneer generally only 30~
How 40cm realizes losslessization, and large format splicing is always the emphasis of research, uses one-faced tapes paper by veneer in traditional handicraft
Bonding is got up, and is sanded by adhesive tape with sander again after press overlays, but this method is easy to cause and splices not close, sand
If glue big with consumption, in adhesive tape, which stays in, easily influences subsequent paint process on veneer.In addition, the decoration of the prior art is thin
Wood generally only has certain wear-resisting property, is easy for breeding bacterium after being damaged such as improper use wearing layer, causes mildew etc., sternly
Ghost image rings beauty, thus embodiment is not achieved in practicability.
It is an object of the present invention to solving the deficiencies in the prior art, a kind of wide dipping decoration of antibacterial large format spelling is provided
Veneer realizes that losslessization obtains large format decorative veneer using reasonable automatic Mosaic technique, avoids wood raw material waste
Meanwhile labour is significantly reduced, realize summary production；In addition, the large format decorative veneer to acquisition uses electrostatic spraying
Technology sprays complex antimicrobials, then the closed method of impregnating resin, obtains while having the decorative veneer of antibacterial, wear-resisting property.
The second object of the present invention is to provide a kind of preparation method of wide dipping decorative veneer of antibacterial large format spelling.
Summary of the invention
The technical solution adopted by the present invention to solve the technical problems is：
A kind of wide dipping decorative veneer of antibacterial large format spelling, which is characterized in that the antibacterial large format spells width and impregnates decoration
Veneer is using veneer dry cold pressing sizing after wood skin softening agent softens surface preparation as raw material, then through spreading, backing, sand
Light, spelling is wide, impregnating resin is dry and sprays the dry acquisition of impregnating resin again after complex antimicrobials；
The wood skin softening agent is formed by the Raw material processing of following parts by weight：70~80 parts of polyvinyl alcohol, glacial acetic acid 10~
15 parts, 3~4 parts of bleeding agent, 1~10 part of deionized water；
The spelling is wide to use heat molten type tree lace or heat curing type tree lace, heat molten type tree lace by the Raw material processing of following parts by weight and

Dry 5~8min under the conditions of 90~120 DEG C；
S7, electrostatic spraying pre-treatment：Veneer surface after step S6 dipping, dry sprays one layer of zinc phosphating film, with enhancing
The adhesive force of complex antimicrobials, while removing the grieshoch on veneer surface；
S8, electrostatic spraying complex antimicrobials：The step S7 veneer handled well is sent directly into powder spraying chamber and carries out spraying composite antibacterial
Agent, complex antimicrobials form one layer of uniform composite antibacterial coating on veneer surface；
S9, closing, drying：The veneer after spraying complex antimicrobials in step S8 is impregnated and is dried again using resin,
Closing is completed to get finished product to complex antimicrobials.
