Abstract

The invention belongs to the field of novel plastic pipe color master batches, and particularly relates to a PPR gray pipe color master batch and a preparation method thereof. The color master batch comprises the following blended components: a carrier resin, a dispersing agent, a surface treating agent, titanium dioxide, carbon black, and an alternative copolymer of an auxiliary agent dimethyl-(naphthalene-1-yl methyl)-(2-octadecanoyl oxyethyl) ammonium chloride and a silane coupling agent KH-550. The PPR pipe prepared from the color master batch component has the advantages of good toughness, environmental stress cracking resistance, good weather resistance and good mechanical properties, and can meet the requirements of related pipe standards.

Description

technical field [0001] The invention belongs to the field of novel plastic pipe color masterbatches, in particular to a PPR gray pipe color masterbatch and a preparation method thereof. Background technique [0002] PPR pipe is a new type of plastic pipe developed and applied in the late 1980s and early 1990s. It is a new building material product that has emerged in my country in recent years. It has the advantages of high strength, heat resistance, and low temperature resistance. PPR pipes have a service life of up to 50 years under the condition of transporting hot water at 70°C and a long-term internal pressure of 1MPa. Therefore, it is widely used in building cold and hot water systems, drinking water systems and adoption systems. [0003] In the past, my country's PPR pipes were mainly imported, mainly products from companies such as Borealis and Hyosung. With the increasing use of PPR pipe products in our country year by year, Yanshan Petrochemical in our country in...
