Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

The utility model provides a paint novel ecological plate of putty structure, including core 2, core surface bonding has

first veneer

1, 3, the putty that comprises polyvinyl alcohol, epoxy glue, hydroxypropyl methyl cellulose, wood flour, talcum powder is paintd to the pit on 2 surfaces of core to make the core surfacing. And putty composed of polyvinyl alcohol, epoxy resin glue, hydroxypropyl methyl cellulose, wood powder and talcum powder is coated in the concave pits 1-1 on the surfaces of the

first veneers

1 and 3, so that the surfaces of the veneers are smooth.

The core plate 2 is formed by pasting a joinery core plate or a plurality of vertical second single plates 2-1, the grain direction of the first single plate 1 is vertical to the grain direction of the plurality of vertical second single plates 2-1, and putty composed of polyvinyl alcohol, epoxy resin glue, hydroxypropyl methyl cellulose, wood powder and talcum powder is coated on the concave pits 2-1-1 on the surfaces of the second single plates 2-1, so that the surfaces of the second single plates are flat, and the adjacent two second single plates 2-1 have the same height.

And decorative surface skins 4 are adhered to the outer surfaces of the first

single plates

1 and 3. The core plate 2 and the

first veneers

1 and 3 are bonded through flame-retardant glue and then are hot-pressed. The first

single plates

1 and 3 can be formed by splicing a plurality of single plates according to the size requirement of the plate. The first

single boards

1 and 3 and the second single board 2-1 may be multilayer single boards. The first veneer and the second veneer can be technical wood veneer or poplar wood veneer. The decorative surface skin can be impregnated with adhesive film-coated paper or solid wood skin.

The pits can be quality problems of uneven board surface, dry flowers, cracks and the like caused by the production process, or raw material problems of scabs, bugles, explosion, decay, bruising and the like caused by tree species.

The putty raw material composition can be 6 parts by weight of rubber powder, 10 parts by weight of wood powder and 100 parts by weight of talcum powder. The glue powder comprises 12 parts by weight of polyvinyl alcohol, 25 parts by weight of epoxy resin glue and 5.5 parts by weight of hydroxypropyl methyl cellulose. The adhesive force and water resistance of the putty and the surface of the artificial board base material are enhanced by the proportion of the polyvinyl alcohol, the epoxy resin glue, the hydroxypropyl methyl cellulose and the wood powder, and the adhesive strength and filling saturation of the putty are enhanced by the proportion of the polyvinyl alcohol, the epoxy resin glue, the hydroxypropyl methyl cellulose and the talcum powder. The larger the specific gravity of polyvinyl alcohol, epoxy resin glue and hydroxypropyl methyl cellulose in the putty is, the higher the bonding strength of the putty is.
