High temperature resistant colouring masterbatch and preparation method thereof

Abstract

The invention discloses a high temperature resistant colouring masterbatch and belongs to the technical field of plastic additives. The colouring masterbatch contains the following raw materials, by weight, 25-50 parts of modified polypropylene, 10-20 parts of a dispersant, 10-18 parts of nano-montmorillonite, 3-8 parts of pigment, 2-5 parts of an antibacterial agent, 2-5 parts of a light stabilizer and 2-8 parts of a reinforced modifier. The invention also discloses a preparation method of the masterbatch. The preparation method comprises steps of material mixing, extrusion, granulation and packaging. In comparison with a high temperature resistant colouring masterbatch in the prior art, the masterbatch provided by the invention has advantages of high temperature resistance, good processability, long service life of the product after being used and wide application range.

Description

technical field [0001] The invention relates to a coloring masterbatch, in particular to a high-temperature-resistant polypropylene 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 ...
