Title
(EN) PREPARATION METHOD FOR PVC BOARD AND PLASTIC FLOOR USING PVC BOARD
(FR) PROCÉDÉ DE PRÉPARATION DE PLAQUE EN PVC ET PLANCHER EN PLASTIQUE UTILISANT UNE PLAQUE EN PVC
(ZH) 一种PVC板的制备方法及使用该PVC板的塑胶地板
Abstract
(EN) The present invention relates to a preparation method for a PVC board, comprising the following steps: mixing a PVC powder, a plasticizer, and a stabilizer at 90-130°C to prepare a mixed powder; uniformly mixing the mixed powder with rubber and a stone powder to prepare a mixture; placing the mixture in an internal mixer for internal mixing until the temperature of the mixture rises to 140-180°C to obtain thermoplastic plastic; open milling the thermoplastic plastic to obtain a sheet-shaped product; and performing pressure forming on the sheet-shaped product. The present invention further provides a plastic floor using the PVC board prepared by the preparation method.
(FR) La présente invention concerne un procédé de préparation d'une plaque en PVC, comprenant les étapes suivantes consistant à : mélanger une poudre de PVC, un plastifiant et un stabilisant à 90-130 °C pour préparer une poudre mélangée ; mélanger uniformément la poudre mélangée avec du caoutchouc et une poudre de pierre pour préparer un mélange ; mettre le mélange dans un mélangeur interne pour un mélange interne jusqu'à ce que la température du mélange augmente jusqu'à 140-180 °C pour obtenir une matière plastique thermoplastique ; réaliser un broyage ouvert du plastique thermoplastique pour obtenir un produit en forme de feuille ; et la réalisation d'un formage par pression sur le produit en forme de feuille. La présente invention concerne en outre un plancher en plastique utilisant la plaque en PVC préparée par le procédé de préparation.
(ZH) 本发明涉及一种PVC板的制备方法,包括如下步骤:将PVC粉、增塑剂和稳定剂在90-130℃下混合制成混合粉;将混合粉与橡胶、石粉混合均匀制成混合物;将混合物置于密炼机中进行密炼直至混合物的温度升至140-180℃,得到热塑性塑料;将热塑性塑料进行开炼得到片状制品;将片状制品加压成型。本发明还提供了使用上述制备方法制备的PVC板的一种塑胶地板。
