Method for preparing greening fence based on waste plastics and straw

Abstract

The invention relates to a method for preparing a greening fence based on waste plastics and straw. The method comprises the following steps: 1) naturally airing the collected plant straws, then cutting and crushing to prepare straw powder for later use; 2) collecting the waste plastics and related products, washing, drying and then performing crushing treatment to perform plastic particles for later use; 3) drying the straw powder till the water content is within 5% and further performing modification treatment on the straw powder; 4) performing steam sterilization on the plastic particles, further drying, mixing with the modified straw powder in the step 3), uniformly mixing and then sending into a granulating machine for granulating to obtain mixed particles for later use; 5) burdening the mixed particles; and 6) putting the materials in the step 5) into a hot runner co-extrusion mold for hot melting and extrusion, well mixing the materials, and then introducing into a hot runner for being jointed with a whole molding production line for molding. The prepared product has great strength, hardness, acid-alkali resistance, corrosion resistance and no deformation and is easy to recover, and is an environment-friendly material.

Description

technical field [0001] The invention relates to the technical field of resource reuse, in particular to a method for preparing green fences based on waste plastics and straws. Background technique [0002] With the development of industry, the application of plastic products has spread all over the fields of industry, agriculture and daily life. The waste plastic waste generated every day in the world cannot be estimated, but it is obvious that it has a great pressure on the environment. In order to deal with these plastics Garbage, the current method is generally landfill, incineration and so on. However, due to the long natural degradation time of ordinary plastic waste, it usually takes more than a hundred years to degrade, and a large amount of methane and other harmful substances will be produced during the degradation process, so the landfill method has been criticized by many experts; while incineration Harmful gases and smoke generated by the law directly affect the...
