High temperature resistant color masterbatch and preparation method thereof

Abstract

Belonging to the technical field of plastic additives, the invention discloses a high temperature resistant color masterbatch. The color masterbatch comprises the following raw materials by weight: 30-50 parts of a polypropylene random copolymer, 10-20 parts of a dispersant, 10-18 parts of nano-montmorillonite, 3-8 parts of a pigment, 2-5 parts of an antibacterial agent, 2-5 parts of a light stabilizer, 0.2-1 part of cerium oxide, and 2-8 parts of a reinforced modifier. The invention also discloses a preparation method of the high temperature resistant color masterbatch. The method consists of the steps of mixing, extrusion, granulation, and packaging. Compared with the high temperature resistant color masterbatches in the prior art, the high temperature resistant color masterbatch provided by the invention has the advantages of good high temperature resistance and processability, long service life of products, and wide range of application.

Description

technical field [0001] The invention relates to a coloring masterbatch, in particular to a high-temperature-resistant coloring masterbatch and a preparation method thereof, belonging to the technical field of plastic additives. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, polypropylene pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. , Widely used in building water supply and drainage, urban and rural water supply and drainage, city gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. [0003] The polypropylene water pipes in the prior art are generally PPR water pipes, which are divided into hot water pipes...
