6. the cooling dipping solidifies jar to room temperature, reclaims the monomer of cooling, and secondary vacuum pumping, and gas residual in the veneer is extracted out, has promptly obtained the dipping veneer.
7. will flood veneer and be made into composite floor board, and promptly obtain dip dyeing and strengthen compound commercial floor with full poplar base plate bonding.
The present embodiment step 2. in maceration extract proportioning process, earlier that oil-soluble dyes are red, yellow, deceive and dissolves in the methyl methacrylate monomer if produce non-Natural color product by 3% concentration, be deployed into shades of colour in proportion with 3% color mother liquor then.
The present embodiment step vacuumizes in 3., and vacuum is reached-0.1Mpa, keeps 10～20min then.Interval 2～3mm when veneer is piled up.
The present embodiment step 4. in nitrogen pressure to 10kg/cm
2, can improve the efficient of impregnating greatly, shorten dip time.
The present embodiment step 5. in secondary can reduce the volatilization of monomer with nitrogen pressure, prevent that veneer from meeting the oxidized variable color of air in heating process, also prevent methymethacrylate at high temperature steam contact inflammable and explosive problem with oxygen.Mode of heating adopts the heating of impregnating autoclave jacket steam, homogeneous heating in jar.And adopting automatic controllable temperature system, the diverse location temperature difference is less than 5 ℃ in jar.And in the process of being heating and curing, pile up for the partial monosomy that prevents to flow out in timber goes out to solidify at the discharge opeing mouth of pipe, design unique cooling system and operated pneumatic valve and replaced drainage system, guarantee that the monomer that drips can discharge timely.
The present embodiment step 6. in after thermal-initiated polymerization, in the chuck that dipping solidifies jar, feed cooling water, make the impregnating autoclave cooling, reclaim after the methyl methacrylate monomer cooling liquid of vaporization in jar, can improve the utilization rate of monomer.
The present embodiment step 7. in, the veneer that dipping is good overlays on veneer, and through operations such as sanding, mortise, top finishings, can obtain versicolor dipping intensified compound commercial floor, whole composite floor surface layer color homogeneous (about 2mm is thick), and beautiful texture.
But the maceration extract long term storage for guaranteeing to configure in the present embodiment has increased refrigeration system to stocking system, and the maceration extract temperature is controlled at below 10 ℃.
All quote in this application as a reference at all documents that the utility model is mentioned, just quoted as a reference separately as each piece document.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after having read above-mentioned instruction content of the present utility model, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
