<p>Provided is a straw plastic for producing geotechnical products and a production method therefor, relating to the technical field of plastic particle production, and particularly the field of production of plastic particles for geotechnical products. Natural straw with a fineness of 300-350 mesh, a talcum powder, kieselguhr, a high-molecular polymer and a plastic auxiliary are mixed, and then granulated by twin screw extrusion; the resulting products can be used for producing the geotechnical products, such as blind ditches, drainage strips and the like; the normal performances of the products can be kept in specific conditions for a maximum time of 180 days; then, the original performances are gradually lost and disintegration occurs to form fragments. The straw plastic disclosed in the invention further has a relatively low processing temperature, and can achieve thermoplastic forming at about 140-160°C, while common thermoplastic plastics require processing temperatures of greater than 230°C.</p> |
