Title (EN) COMPOSITE FLOOR AND PREPARATION METHOD THEREFOR
(FR) PLANCHER COMPOSITE ET PROCÉDÉ DE PRÉPARATION ASSOCIÉ
(ZH) 复合地板及其制备方法
Abstract:
(EN) Provided are a composite floor and a preparation method therefor. The composite floor comprises a co-extruded layer formed by means of co-extrusion press process, and the co-extruded layer comprises a first PVC layer, a PVC foam layer and a second PVC layer that are arranged successively from top to bottom. The composite floor above uses a PVC foam layer as a main material layer, reducing the overall weight of the floor, and the first PVC layer and the second PVC layer are respectively provided on the two sides of the PVC foam layer, making the properties of the composite floor more stable. The present invention uses co-extrusion press process for forming, avoiding bonding with glue and making the process more environmentally friendly. The processing procedure is simple, and the layers are more closely combined. There are fewer delaminations and less warpage due to the influence of environmental changes, and the composite floor has a low expansion ratio, a low shrinkage rate, excellent performances, and a long service life.
(FR) La présente invention concerne un plancher composite et un procédé de préparation associé. Le plancher composite comprend une couche co-extrudée formée au moyen d'un procédé de co-extrusion-pressage, et la couche co-extrudée comprend une première couche de PVC, une couche de mousse de PVC et une seconde couche de PVC qui sont disposées successivement de haut en bas. Le plancher composite ci-dessus utilise une couche de mousse de PVC en tant que couche de matériau principal, réduisant le poids global du plancher, et la première couche de PVC et la seconde couche de PVC sont respectivement disposées sur les deux côtés de la couche de mousse de PVC, rendant les propriétés du plancher composite plus stables. La présente invention utilise un procédé de co-extrusion pressage pour le formage, permettant d'éviter une liaison avec de la colle et de rendre le procédé plus respectueux de l'environnement. La procédure de traitement est simple, et les couches sont plus étroitement combinées. Il y a moins de stratifications et moins de gauchissement dus à l'influence des changements environnementaux, et le plancher composite a un faible taux d'expansion, un faible taux de rétraction, d'excellentes performances, et une longue durée de vie.
(ZH) 提供一种复合地板及其制备方法，复合地板包括采用共挤工艺压制成型的共挤层，所述共挤层包括从上至下依次设置的第一石塑层，石塑发泡层和第二石塑层。上述复合地板，以石塑发泡层为主体材料层，减轻了地板的整体重量，在石塑发泡层的两侧分别设置第一石塑层和第二石塑层，使得复合地板性能更加稳定。采用共挤工艺压制成型，避免使用胶水粘合，更加环保，且加工工序简单，各层之间结合更加紧密，由于环境变化的影响而出现分层以及翘曲的情况较少，复合地板膨胀率低，收缩率低，性能优异，使用寿命长。
