Abstract

The invention discloses a special compounded level marking line color master batch for a PP-RCT cold water pipe, and a preparation method thereof. Raw materials of the color master batch comprise, byweight, 75-90 parts of Yanshan Petrochemical PP-RCT3120, 6-16 parts of phthalocyanine blue 7090, 8-18 parts of an antioxidant, 9-20 parts of a processing aid and 6-15 parts of a surfactant. Compared with color master batches in the prior art, the color master batch in the invention has the characteristics of high dispersibility, high color saturation, strong coating property and good heat resistance, and makes a line have a color saturation reaching 91.5% or above; and the oxidation induction time of the line in the production process is prolonged, and reaches about 60min, so the aging resistance of the color master batch is improved, thereby the produced pipe has a long service life.

Description

technical field [0001] The invention relates to the technical field of raw material processing of plastic pipes, in particular to a PP-RCT cold water pipe special-purpose compounding-grade marking line color masterbatch and a preparation method thereof. Background technique [0002] With the improvement of the application of plastic products in daily life and the improvement of processing technology, in recent years, the domestic PP-R pipe market has developed rapidly, and it has been widely used in industrial and building water supply and drainage pipes. However, the domestic construction environment is prone to cracking and damage of PP-R pipes on site due to insufficient toughness. Therefore, improving the toughness and pressure bearing capacity of PP-R pipes has become a very serious problem. With the emergence of a random copolymerized polypropylene (PP-RCT) resin with improved crystallization, it has led the current development trend and trend of international polypro...
