Abstract

The invention relates to the extruded wood plastic manufacturing field, and concretely relates to a wood plastic plate and its making method. The wood plastic plate comprises the following raw materials: 90-110Kg of polyvinyl chloride, 45-55Kg of wood powder, 45-55Kg of light calcium carbonate, 5-6Kg of a composite stabilizing agent, 1-1.5Kg of a lubricant, 12-16Kg of a foaming conditioning agent, 1.4-1.6Kg of an AC foaming agent, 0.8-1.1Kg of a trisalt, and 0.9-1.1Kg of a plasticizer. The preparation method of the wood plastic plate comprises the following steps: preparing the raw materials; uniformly mixing the raw materials; cooling the well mixed raw materials; adding the cooled raw materials to an extruder, carrying out mold head thermal molding and stock mold pipelining cooling molding, and carrying out extrusion molding; and cutting the plate subjected to the extrusion molding, and disposing the plate. The wood plastic plate has water, moisture and mildew resisting effects.

Description

technical field [0001] The invention relates to the field of extruded wood-plastic manufacturing, in particular to a wood-plastic board and a manufacturing method thereof. Background technique [0002] Natural wood boards have defects such as easy shrinkage and cracking, mutability when exposed to water, and flammability when exposed to fire. Physically harmless. Compounding wood powder and plastic is one of the main contents of follow-up research, but due to the poor compatibility of wood powder and plastic. At present, wood-plastic panels have gradually entered people's lives. Due to the limitations of their characteristics and shapes, the formulation and production methods of wood-plastic panels are restricted, which in turn affects the popularization and use. Contents of the invention [0003] The object of the present invention is to provide a wood-plastic board and a manufacturing method thereof in order to solve the above problems. [0004] The technical scheme p...
