Preparation method of special color master batch for ultrahigh-molecular-weight polyethylene spinning

Abstract

The invention relates to a preparation method of special color master batch for ultrahigh-molecular-weight polyethylene spinning. The preparation method is implemented through the following four steps of: 1) selecting high-molecular-weight polyethylene resin as main materials, then adding organic pigment powder, antioxidant, light stabilizer and mineral oil, and mixing by using a mixing machine to prepare colored resin mixture; 2) extruding in a fused state by using an exhaust-type double-screw extruder to obtain a plurality of lines; cooling and solidifying the extruded colored lines through a water trough, and cutting the lines into colored master batch grains by using a grain cutting machine; 3) fully drying the colored master batch grains by using a dryer; and 4) grinding the colored master batch grains into even powder to obtain the special color master batch with uniform grain size for ultrahigh-molecular-weight polyethylene spinning. The preparation method of special color master batch for ultrahigh-molecular-weight polyethylene spinning has the advantages that the demands for various colors needed for ultrahigh-molecular-weight polyethylene spinning are met, the production technology is simple, the cost is low and the preparation method is the best technique for preparing various colored fibers at present.

Description

technical field [0001] The invention relates to a method for preparing raw materials in the textile industry, in particular to a method for preparing a special color masterbatch for ultra-high molecular weight polyethylene spinning. Background technique [0002] Ultra-high molecular weight polyethylene fiber is one of the high-tech fibers in the world today. Its molecular weight is extremely high, reaching more than 2 million (×10 4 ); the fiber has high molecular density, no functional groups, smooth surface, and cannot be dyed, so the ultra-high molecular weight polyethylene fibers produced at home and abroad are all white, and its fibers are limited in special industrial textiles and marine engineering ropes and fishing nets. Wide range of applications in the field, such as the production of colored ultra-high molecular weight polyethylene fibers, must be mixed with high molecular weight polyethylene color masterbatch and ultra-high molecular weight polyethylene resin to ...

Problems solved by technology

[0010] According to the above-mentioned existing technical data, color masterbatches similar to polyethylene are only used in the coloring of polyethylene plastic products and in the fields of polypropylene, polyamide, and polyester PET spinning, and cannot be used for ultra-high molecular weight polyethylene spinning colored fibers. masterbatch
