Abstract

The invention discloses a halogen-free flame retardant plastic geotechnical grille master batch for a mine, which consists of polyolefine, special carbon black, composite flame retardants, compatilizer, modified nanometer reinforcing materials, processing auxiliary agents and antioxidizer according to a certain proportioning ratio, wherein the composite flame retardants are compounds of nanometer inorganic flame retardants, micro-capsulated red phosphorus and phosphoric acid ester flame retardants. When the master batch prepared by the method is added in grilles, the performance is stable, the flame retardant performance is good, and the environment protection effect is good.

Description

technical field [0001] The invention relates to a plastic filling masterbatch, in particular to a halogen-free flame-retardant masterbatch for mining plastic geogrids. Background technique [0002] Plastic geogrid is a square or rectangular polymer mesh formed by stretching. After several times of stretching and orientation in the following suitable temperature range, the product can produce a tensile strength that is several times or even ten times higher than that of the original unstretched product. Therefore, plastic geogrid has high strength and has been widely used in geotechnical engineering, such as river embankment, hillside anti-seepage and landslide, anti-slide of mixed stone engineering, land foundation strengthening, road, railway foundation strengthening, coal mine roadway support, etc., and has obtained It has good application effect and economic effect. At present, there have been some studies, such as optimizing the distribution of vertical and horizontal ...
