Embodiment Construction

[0015] In order to describe the present invention in detail, the following will be further described in conjunction with specific examples,

[0016] A method for processing corn stalks to produce wood-plastic materials. The main process steps include: first, fully drying the corn stalks, cutting and pulverizing them, and then finely pulverizing them into fineness of 60-80 meshes and moisture content of 3-5 % of corn stalk powder, then mixed according to the following mass percentages:

[0017]

[0018]

[0019] The temperature of the mixture is 130-150°C, and the wood-plastic products are obtained through the steps of granulation, extrusion, molding, sanding and embossing. The granulation temperature is 180-220°C, and the extrusion temperature is 150-175°C.

Abstract

The invention discloses a method for producing a wood-plastic material by processing corn straws, which relates to the technical field of production and process of the wood-plastic composite material. The method mainly comprises the following steps: firstly processing the corn straws into the corn straw powder, of which the fineness is 60-80 meshes and water content is 3-5%; mixing the following materials of 55-90% of corn straw powder, 25-35% of waste plastics, 6-20% of filing materials, 3-16% of heat stabilizer, 3-22% of lubricant and 3-17% of assistant, wherein the material mixing temperature is 130-150 DEG C; and performing prilling, extruding, modeling, sanding, knurling and the like to obtain the wood-plastic product, wherein the prilling temperature is 180-220 DEG C, and the extruding temperature is 150-175 DEG C. The raw materials provided by the invention can be easily obtained, so that the production cost is low; and the waste resources can be recycled and then regenerated, so that the content of the wood fiber and the silica of the products are high, the impact strength is high and can reach 1.5 times that of the national standard, and the service life is long.

Description

Technical field: [0001] The invention relates to the technical field of production and processing of plastic-wood composite materials, in particular to a method for producing plastic-wood materials by processing corn stalks. Background technique: [0002] Wood-plastic composite materials have the advantages of both plant fibers and plastics, and have a wide range of applications, covering almost all fields of use of logs, plastics, plastic steel, aluminum alloys and other similar composite materials. At the same time, they also solve the recycling of waste resources in the plastic and wood industries. Take advantage of the problem. [0003] Its main features are: resource utilization of raw materials, plasticization of products, environmental protection in use, economical cost, recycling and regeneration. [0004] The earth we live on has undergone more than four billion years of evolution to create an environment suitable for biological survival. Since the past 10,000 yea...
