Manufacturing method of plastic-wood board

Abstract

The invention relates to the technical field of plastic-wood board manufacturing, in particular to a manufacturing method of a plastic-wood board. The manufacturing method comprises the following specific steps that a, a prepared mixture is added into a mixer for mixing, wherein the mixture comprises PVC polyvinyl chloride resin, Chinese fir powder, calcium carbonate, a stabilizer, a foaming agent, a lubricant and toner; b, the mixture is placed into an extrusion molding machine, and the mixture is extruded after the temperature of each area of the extrusion molding machine is adjusted; c, theextruded mixture and an ASA material are simultaneously extruded through an extruder, and meanwhile the mixture and the ASA material are extruded together by using a die; d, the molded product in thedie is cooled and formed by using cooling water; and e, surface treatment is carried out on the shaped product. The raw materials are prepared, the plastic-wood board is formed by synchronous co-extrusion, and the ASA material is extruded, molded and pressed onto the plastic-wood board to form a protective layer. Abrasion resistance and weather resistance of the plastic-wood board are improved, and the phenomenon that aging is accelerated under the influence of outdoor environments such as ultraviolet rays and the like is avoided.

Description

technical field [0001] The invention relates to the technical field of manufacturing wood-plastic boards, in particular to a method for manufacturing wood-plastic boards. Background technique [0002] At present, there are defects in outdoor decorative building materials: floors such as floor tiles and stone slabs are relatively bulky, difficult for secondary processing, and the texture is not strong and the beautification effect is insufficient; wooden boards have the advantages of light weight and beautiful appearance. However, the existing plastic-wood panels have poor wear resistance and weather resistance, and are prone to aging when used outdoors. Contents of the invention [0003] In order to solve the deficiencies of the prior art described in the background technology, the present invention provides a method for manufacturing wood-plastic boards, by configuring raw materials, forming wood-plastic boards through synchronous co-extrusion, and extruding ASA materials...
