Problems solved by technology

[0002] Today's thermoplastic extrusion technology adds wood powder to the board, pipe, and profile to achieve its functions (hardening, cost reduction) and the proportion has not exceeded 30% of the total. It only improves the deformation characteristics of plastic products and cannot Fundamentally solve the requirement of emphasizing deformation in application, we especially propose the application of building formwork
Traditionally used bamboo and wooden formworks are loose and easy to peel and separate after the water of the concrete is immersed in the formwork, which will affect the quality of pouring after expansion. When using plastic formwork, the plastic will also shrink due to the ambient temperature. It directly affects the pouring quality, and the use of bamboo, wood, and metal formwork uses a large amount of chemical glue, chemical release agent, and other chemical substances that are harmful to the environment and human health, which is not conducive to environmental protection

Abstract

The invention discloses a wood plastic environment friendly ecological material and a production technology of the wood plastic environment friendly ecological material, belongs to the technical field of material design, and aims to provide a firm wood plastic environment friendly ecological material with consistent quality. The material comprises, by mass, 60 to 70 parts of plant fiber, 30 to 40 parts of hot melt plastic and 3 to 8 of additives. The preparation method includes weighing each component; pouring plant fiber powder into a mixer set to be subjected to coupling dehydration, then adding plastic powder and additives to subject the powder to preplasticization mixing, and obtaining a pre-polymer; adding the pre-polymer into an internal mixer to be plasticized fully and mixed evenly, placing the pre-polymer into an insulation hopper of an extruder through a delivery tray, so that plant fiber and thermoplastic polymer blends and surfaces pass through co-extrusion plastic; performing surface coating through a surface functional material coating device, and manufacturing products through a hot rolling device, a cool rolling device and a tractor; and cutting a needed length through a cutting machine.

Description

technical field [0001] The invention discloses a material, specifically a wood-plastic environment-friendly ecological material, and also discloses a production process of the wood-plastic environment-friendly ecological material; it belongs to the technical field of material design. Background technique [0002] Today's thermoplastic extrusion technology adds wood powder to the board, pipe, and profile to achieve its functions (hardening, cost reduction) and the proportion has not exceeded 30% of the total. It only improves the deformation characteristics of plastic products and cannot To fundamentally solve the requirement of emphasizing deformation in application, we especially propose the application of building formwork. Traditionally used bamboo and wooden formworks are loose and easy to peel and separate after the water of the concrete is immersed in the formwork, which will affect the quality of pouring after expansion. When using plastic formwork, the plastic will a...
