Abstract

The invention relates to a coloring masterbatch for a PPR tube. The masterbatch is prepared from the following raw materials in percentage by mass: 50-65 percent of rutile titanium dioxide, 28-40 percent of PPR resin, 3.9-9 percent of iron oxide red, 1.0-1.5 percent of titanium yellow, 0.1-0.5 percent of carbon black and 0.5-1.5 percent of polysiloxane, wherein the rutile titanium dioxide has an average grain size of 0.2-0.25 mu m and a refractive index of 2.7, has strong covering power and strong ultraviolet absorbability, and can be used for resisting temperature of 300 DEG C; and the carbon black is produced by a channel process and has an average grain size of 10-27nm. The invention further discloses a preparation method of the coloring masterbatch. The method comprises the steps of selecting raw materials, metering, mixing raw materials, cooling, granulating, packaging and the like. The coloring masterbatch has the advantages of high content of titanium dioxide, good dispersion, good light covering performance and discoloration prevention.

Description

technical field [0001] The invention relates to a coloring masterbatch and a preparation method thereof, in particular to a coloring masterbatch for PPR pipes and a preparation method thereof. Background technique [0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life.
