A process of wrapping the surface layer of solid wood lines with modified pvc

Abstract

The invention discloses a process for wrapping the surface layer of solid wood moldings with modified PVC. The key points of the technical scheme include the following steps: Step 1: Use a plastic granulator to extrude and granulate the modified PVC composite material; Step 2: Put The modified PVC particles are put into the hopper of the extruder, and the solid wood lines are placed in the center of the mold. Under the high temperature heating of the extruder, the modified PVC particles change from solid to viscous fluid state. Next, enter the PVC viscous fluid into the mold; step 3: the extruder cools down to room temperature, the PVC viscous fluid is condensed into a solid state after cooling, and the modified PVC composite solid wood lines are obtained; the PVC composite material includes the following materials: polyvinyl chloride, Calcium carbonate, wood powder, foaming agent, paraffin wax, composite stabilizer, pigment, the combination strength of modified PVC composite material and solid wood lines in the present invention is relatively high, while the composite heat stabilizer improves thermal stability, the product is not easy to " Zinc burn" phenomenon.

Description

technical field [0001] The invention relates to the technical field of processing solid wood moldings, in particular to a technique for wrapping the surface layer of solid wood moldings with modified PVC. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of furniture, doors and windows. Doors, windows and furniture are more and more sought after by people because of their high-end quality. However, the materials of doors, windows and furniture are all derived from natural wood. The density of natural wood is uneven during the growth process, accompanied by climate changes during use, and some poor-quality sealing paints cannot effectively prevent air from entering the wood fibers, resulting in wood in a high-humidity environment, or with the With the extension of use time, wood absorbs moisture in the air, resulting in changes in internal and external stress, resulting in cracking and deformatio...

[0002] With the improvement of living standards, people have higher and higher requirements for the quality of furniture, doors and windows. Doors, windows and furniture are more and more sought after by people because of their high-end quality. However, the materials of doors, windows and furniture are all derived from natural wood. The density of natural wood is uneven during the growth process, accompanied by climate changes during use, and some poor-quality sealing paints cannot effectively prevent air from entering the wood fibers, resulting in wood in a high-humidity environment, or with the Prolonged use time, wood absorbs moisture in the air, resulting in changes in internal and external stress, resulting in cracking and deformation

[0003] In view of this, current research has found that covering the surface of solid wood furniture with a PVC layer can enhance the performance of doors, windows and furniture, but the bonding effect between PVC and wood is not good, and the actual application effect is poor.
