Abstract

The invention discloses a high-low temperature and static resistant PE corrugated pipe filling master batch which is prepared from the following raw material components in parts by weight: 50-60 parts of low density polyethylene, 30-40 parts of carbon black, 4-6 parts of silicon-calcium-magnesium (SCM) whiskers, 1-2 parts of coconut diethanolamide, 1-2 parts of lauric diethanolamide,1-2 parts of sodium gluconate, 0.1-0.5 part of a coldproof plasticizer, 1-2 parts of barium stearate, 5-8 parts of talcum powder, 0.2-0.4 part of an anti-oxidant 215 and 10-15 parts of an enhancer. The master batch can be subjected to extruding pelletization by a conventional double-screw extruder, and added for processing of a corrugated pipe, so that the processed corrugated pipe has the advantages of being resistant to high-low temperature, high in ring stiffness, light in weight, high in oxidation resistance, low in material consumption, convenient for construction and mounting, and high in static-resistant performance.

Description

technical field [0001] The invention relates to the field of bellows filling masterbatch, in particular to a high-low temperature resistant and antistatic PE bellows filling masterbatch and a preparation method thereof. Background technique [0002] With the development of the national economy and urban construction, the demand for large-diameter plastic drainage pipes to replace traditional cement pipes has become increasingly strong. However, the ring stiffness of large-diameter plastic pipes over 1 meter is an urgent problem to be solved. In order to meet the requirements of the project for the rigidity of the pipe ring, the manufacturer generally adopts the method of lining the steel plate or thickening the pipe wall, which is costly and complicated. [0003] Silicon-calcium-magnesium (SCM) whisker is a new type of silicate material with a one-dimensional single crystal structure, a diameter of 0.2-0.8 μm, and a length of 20-60 μm. It has extremely high mechanical prope...
