The color master batch is a concentrate prepared by carrying a plastic additive in an extraordinary amount in resin, and when a plastic product is manufactured, the plastic additive does not need to be added, but only the corresponding master batch needs to be added. The color master batch is prepared from carrier resin, pigment and dispersant by mixing, melt extruding, and granulating to obtain granular master batch with particle size equal to that of resin. The color master batch is one of the most main forms of plastic auxiliary agent application in the world at present, has simple process and convenient use, is convenient for realizing production automation, improves the labor productivity, avoids environmental pollution and is beneficial to clean and civilized production of workers.
Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipelines, the PPR pipe has the advantages of material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scale formation, simple and convenient construction and maintenance, long service life and the like, and is widely applied to the construction industry, municipal administration, industry and agricultural field such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheaths, industrial fluid delivery, agricultural irrigation and the like. In recent years, with the increasing market demands of industries such as construction industry, municipal engineering, hydraulic engineering, agriculture and industry, the PPR pipe industry in China shows a high-speed development situation. While the output of plastic pipelines in China is increased, the quality requirements of consumers on the aspects of environmental protection, health, durability and the like of products are continuously improved. The PPR water supply pipe has special requirements on color masterbatch: 1. certain covering power; 2. the pigment has good high temperature resistance; 3. has certain weather resistance.

However, the PPR pipe specified by the national standard GB18742-2017 should not contain calcium carbonate, barium sulfate and other components, and the color master batch cannot meet the technical requirements of the new national standard.
Patent application CN104059299A discloses a special coloring master batch for PPR pipes and a preparation method thereof, wherein the master batch is composed of the following raw materials in parts by weight: 40-60 parts of carrier resin, 35-55 parts of pigment, 0.5-5 parts of dispersing agent, 0.1-3 parts of antioxidant and 0.1-3 parts of antibacterial agent. The preferred pigments of the invention are titanium dioxide, carbon black and permanent yellow, although the coloring power of the permanent yellow is strong, the high temperature resistance is poor, and the color change is easy to generate in the processing process, so that the normal color of the pipe is influenced; in addition, the dispersant added in the invention is preferably polyethylene glycol 200 and polyethylene glycol 400, the polyethylene glycol is stable under general conditions, but the polyethylene glycol can react with oxygen in the air at 120 ℃ or higher, so that the dispersion effect of the polyethylene glycol is lost, and the coloring master batch of the invention still cannot solve the existing problems such as: poor light-shielding property, poor dispersibility, easy color change and uneven inner surface to store dirt and dirty.
Patent application CN104497424A discloses a coloring master batch for a PPR pipe and a preparation method thereof, wherein the master batch comprises the following raw materials in percentage by mass: 50-65% of rutile titanium dioxide, 28-40% of PPR resin, 3.9-9% of iron oxide red, 1.0-1.5% of titanium yellow, 0.1-0.5% of carbon black and 0.5-1.5% of polysiloxane; the rutile titanium dioxide has the average particle size of 0.2-0.25 mu m and the refractive index of 2.7, has strong covering power and strong ultraviolet absorption capacity, and can resist the temperature of 300 ℃; the carbon black is pigment carbon black with the average particle size of 10-27 nm produced by a tank method. The coloring master batch disclosed by the invention adopts PPR4220 or PPR2400 as a carrier, so that the melt index is low and the low-temperature falling performance is poor.
