Abstract

The invention provides a color masterbatch for polyolefin pipes, pipe fittings and inspection wells. The color masterbatch comprises, by weight, 40-70 parts of pigment, 20-50 parts of polyolefin resin, 5-10 parts of processing agent, 0.1-2 parts of heat stabilizer, 0.1-5 parts of dispersing agent, 0.1-2 parts of antibacterial agent and 0.1-1.5 parts of antistatic agent. The color masterbatch is high in dispersibility, and accordingly, weather and pressure resistance properties of the pipes are improved. According to the color masterbatch for the polyolefin pipes, the pipe fittings and the inspection wells, color intensity reaches 95-105; mobility resistance is larger than 4; heat resistance is larger than 4, and each of three grades is smaller than or equal to 3; melt flow rate is 30-50g / 10min; OIT (oxidative induction time) is more than 20 minutes; and if the masterbatch is black, the content of carbon black is 38-41 parts.

Description

technical field [0001] The invention relates to the field of plastic building material production, in particular to a color masterbatch applied to polyolefin pipes, pipe fittings and inspection wells. Background technique [0002] Using color masterbatch (concentrated masterbatch) to color plastic as a whole is a new plastic coloring process that has only been developed in recent years. According to different coloring requirements, it is mixed with the resin to be colored according to a certain ratio, and then molded to obtain colored plastic products. Color masterbatch can be evenly dispersed in the melt during the molding process, and the country has always relied on foreign imports. Polyolefin color masterbatch is colored concentrated granules, smooth surface, no voids and bubbles, heat resistance not less than 200 ° C for 80 minutes; migration resistance greater than 4. The colored plastic products have no color spots and no color stripes, and are suitable for all kind...
