Description
Technical field
The invention belongs to wood processing fields, and in particular to a kind of fire-retardant large format spelling is wide to impregnate decorative veneer and its manufacture
Method.
Technical background
Decorative veneer is a kind of widely used house decorative material, because the substrate of decorative veneer be generally decorative pattern it is beautiful,
Fine quality rare tree, and production requirement material diameter is coarse, and limit its development.A development with advances in technology,
It is compound by fast growing wood or artificial board substrate and the lamination of precious timber veneer, under the premise of ensuring product " dicoration ", greatly
The utilization efficiency of amplitude raising precious timber.Currently, veneer overlay house ornamentation, solid wooden compound floor and in terms of with
It is widely used, but it is decorative faced to use veneer to carry out, and when especially carrying out veneer to artificial board substrate, still has
Technical difficulty.
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 insufficient；According to current process, on substrate or veneer after gluing, then hot pressing or cold pressing are carried out,
It 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 has 30~40cm,
How losslessization is realized, large format splicing is always the emphasis of research, bonds veneer using one-faced tapes paper in traditional handicraft
Get up, be sanded by adhesive tape with sander again after press overlays, but this method is easy to cause that splicing is close, abrasive band disappears
If consumption is big, the glue in adhesive tape stays in easily influences subsequent paint process on veneer.In addition, the decorative veneer one of the prior art
As do not have flame retardant property, as house decorative material, having certain flame retardant property is necessary.So needing to grind
Send out the large format decorative veneer with flame retardant efficiency a kind of, while the decorative veneer also has environmentally friendly, wear-resisting, on-deformable spy
Point.
Summary of the invention
It is an object of the present invention to solving the deficiencies in the prior art, a kind of wide dipping decoration of fire-retardant large format spelling is provided
Veneer, firstly, realizing that losslessization obtains large format decorative veneer using reasonable automatic Mosaic technique, avoiding wood raw material
While waste, labour is significantly reduced, realizes summary production；Secondly, using flame-retardant impregnating resin resin dipping thin wood twice,
Assign veneer certain flame retardant property；Furthermore the agent of Electrostatic Spray Technology spraying abrasion-proof is used to the large format decorative veneer of acquisition,
The closed method of flame-retarded resin is impregnated again, obtains while having the decorative veneer of anti-flammability and wear-resisting property.
The second object of the present invention is to provide a kind of preparation method of fire-retardant wide dipping decorative veneer of large format spelling.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of fire-retardant wide dipping decorative veneer of large format spelling, which is characterized in that the large format spells width and impregnates decorative veneer
Using veneer dry cold pressing sizing after wood skin softening agent softens surface preparation as raw material, then through spreading, backing, sanding, spelling
The dry acquisition of flame-retarded resin is impregnated after wide, dipping flame-retarded resin drying and spraying abrasion-proof agent again；
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；
