Abstract

The invention discloses a preparation method for a low temperature resistant geogrid. The preparation method comprises the following operating steps: (1) preparing a low temperature resistant additive, namely, placing aluminium oxide, 3-hydroxyl-1-adamantaneacetic acid, N,N-di(octyl aminoethyl) glycine hydrochloride, titanium dioxide and tungsten disulphide into a ball grinding mill, mixing at a high speed to prepare the low temperature resistant additive; (2) mixing HDPE (High-Density Polyethylene), an antioxidant DLTP (Dilauryl Thiodipropionate), tetrabromo bisphenol S, heptamethylnonane and dinonyl phthalate, placing the mixture in a high-speed mixing machine, mixing at a high speed, adding the low temperature resistant additive into the high-speed mixing machine, and continuing mixing; (3) placing the mixture which is obtained in the step (2) into an extruding machine for melting and extruding to prepare a plate; (4) punching the plate to obtain mesh holes through a punching machine; (5) performing unidirectional stretching and subsequent further horizontal stretching on a porous plate after the porous plate is heated through a preheating device so as to form a unidirectional or bidirectional stretched grid. The geogrid prepared by the preparation has good low temperature resistance, and can work normally in a low temperature environment and ensure the quality of a product.

Description

technical field [0001] The invention belongs to the field of geogrid manufacturing, and in particular relates to a preparation method of low-temperature resistant geogrid. Background technique [0002] With the rapid development of my country's civil engineering construction industry, it has effectively driven the development of civil engineering materials industry. At present, geogrids are often used in road construction, which has the effect of increasing the bearing capacity of the roadbed and prolonging the service life of the roadbed; preventing road surface subsidence or cracks, keeping the ground beautiful and tidy; convenient construction, saving time and effort, shortening The construction period reduces maintenance costs; the soil slope is enhanced to prevent soil erosion; the cushion thickness is reduced to save cost. At present, geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted po...
