specific Embodiment approach

[0018] Specific embodiments, the present embodiment is a kind of preparation method of paper-based thin wood veneer PVC wood-plastic foam floor, carried out according to the following specific steps:

[0019] 1. Pretreatment of PVC wood-plastic foam floor base material. The floor is a PVC wood-plastic foam floor with uniform cell distribution and extruded by a single-screw extruder by adding foaming agent. The specification of the PVC wood-plastic floor base material is 1200mm×138mm×12mm, which is sanded with 200 mesh sandpaper or planed to remove the thermoplastic layer on the surface of the wood-plastic floor to obtain a PVC wood-plastic floor with a smooth surface and a certain roughness. foam floor substrate;

[0020] 2. Prepare paper-based veneer. The paper-based veneer used is a decorative veneer material bonded with kraft paper on the back and solid wood veneer on the front. The thickness of the paper-based veneer is 0.15mm-0.3mm, and the size of the cut paper-based ven...

Abstract

The invention relates to a preparation method of paper-based veneer veneered PVC wood-plastic foam floor, which mainly solves the problems that the existing wood-plastic floor lacks the natural texture of wood and the problem of difficult bonding between the decorative veneer veneer and the wood-plastic floor base material . The veneering method of the present invention is simple, the veneering cost is low, the glue is not easy to open and bubble, no need to mix glue, the dipping peeling strength and gluing strength are high, and the best decorative performance of the veneer is protected. The invention is composed of PVC wood-plastic foamed floor substrate, styrene-acrylate core-shell emulsion pasted with wood-plastic substrate and decorative veneer, and paper-based veneer. The invention uses the styrene-acrylate core-shell emulsion to bond and shape the paper-based veneer and the PVC wood-plastic foam floor through a cold pressing method. The invention can be applied to the method of sticking paper-based veneer on the surface of PVC wood-plastic foam floor.

Description

technical field [0001] The invention relates to a method for preparing paper-based thin wood veneer PVC wood-plastic foam floor Background technique [0002] PVC wood-plastic foam floor is a new type of floor made of wood fiber, PVC thermoplastic, foaming agent, various processing aids, etc. Utilization and other advantages, and has the processing characteristics of wood, has high economic benefits, and can be widely used for floor laying in various indoor environments. [0003] The texture and texture of PVC wood-plastic foam floor cannot meet the decorative requirements of the floor appearance, and it needs to be veneered with other non-solid wood floors. The commonly used decorative thin wood veneer has extremely high decorative advantages and cannot be found now. A decorative material that can replace decorative thin wood veneers pasted with PVC wood-plastic foam flooring. The use of paper-based thin wood veneer can not only meet the decorative requirements of the floo...
