Problems solved by technology

[0006] The third generation, which appeared in the 1980s, is called the third-generation polyethylene pipe special material PE100. PE100 means that at 20°C, polyethylene pipes can still maintain a minimum required strength of 10MPa after 50 years, and have excellent The ability to resist rapid cracking and crack growth, there is no such generation of materials in China
[0025] However, so far, the art has not developed a carbon black masterbatch that can be used to prepare PE100 pipes with all the excellent properties mentioned above

[0057] In a second aspect of the present invention, a method for preparing carbon black masterbatch for polyethylene pipes is provided, the method comprising:

[0058] The carbon black of 35-100 weight part is mixed with the butylbenzene pyridine copolymer of 1.75-20 weight part;

[0059] Add 100 parts by weight of ultra-high molecular weight polyethylene with a molecular weight of 1.50-4 million (preferably about 2.5 million) and an antioxidant of 0-10 parts by weight into the mixture, mix uniformly and then discharge to obtain the polyethylene pipe. Carbon black masterbatch.

[0060] Preferably, 35-100 parts by weight of the carbon black and 1.75-20 parts by weight of the butylfenene copolymer are mixed in an internal mixer.

[0061] Preferably, the butylfenazole copolymer is prepared by emulsion polymerization, and then the latex is demulsified and dried.

[0062] In the third aspect of the present invention, a kind of preparation method of PE100 pipe compounding is provi...

Embodiment 1

[0079] First put carbon black (brand: N110, average particle size 10-15nm, produced by Cabot Company) and styrene-butadiene pyridine copolymer (produced by Zibo Heli Chemical Co., Ltd.) into a continuous internal mixer, and process at 120°C 30 minutes, then add ultra-high molecular weight polyethylene resin (produced by Sinopec Qilu Petrochemical Co., Ltd.), antioxidant 1010 (produced by Ciba Specialty Chemicals in Switzerland), discharge and granulate after melt blending, to obtain the polymer compound of the present invention Carbon black masterbatch for vinyl pipes. Among them, 100 parts by weight of ultra-high molecular weight polyethylene, 30 parts by weight of carbon black, 1.75 parts by weight of butylfenene copolymer, and 0.2 parts by weight of antioxidant. After simple mechanical blending of high-density polyethylene pipe base material (brand YJH041, produced by Sinopec Shanghai Petrochemical Co., Ltd.) and the above-prepared color masterbatch in a high-speed mixer at...

Embodiment 2

[0081] The production process of the carbon black masterbatch for polyethylene pipes is the same as in Example 1. The specific formula of the color masterbatch is: 100 parts by weight of ultra-high molecular weight polyethylene, 50 parts by weight of carbon black, 10 parts by weight of styrene-butadiene pyridine copolymer, and 2 parts by weight of antioxidant. The production process of the pipe is the same as that of Example 1 except that the weight ratio of the high-density polyethylene pipe base material to the color masterbatch is changed to 100:8.

[0082] The specific performance test results are shown in Table 1 below.

Abstract

The invention relates a carbon black color master batch for polyethylene (PE) pipes and a preparation method thereof. The carbon black color master batch for PE pipes comprises the following components: 100 parts by weight of ultrahigh molecular weight PE with molecular weight of 1,500,000-4,000,000, 35-100 parts by weight of carbon black, 1.75-20 parts by weight of pyridine styrene butadiene copolymer and 0-10 parts by weight of antioxidant. The invention also provides a preparation method of the carbon black color master batch for PE pipes and a preparation method of a PE100 pipe mixing ingredient.

Description

technical field [0001] The invention relates to a carbon black master batch for polyethylene (PE) pipes and a preparation method thereof, more specifically, to a carbon black master batch for PE100 pipes and a preparation method thereof. Background technique [0002] Polyolefin is currently a type of polymer material with the widest application range and the largest output. my country has a market demand for polyolefins of more than 20 million tons per year. The output value of direct products is hundreds of billions of yuan, and the output value of indirect products is trillions of yuan. Half depend on imports. It costs tens of billions of dollars to import polyolefin products in my country every year, mainly for high-performance polyolefin special materials, such as high-grade PE100 grade polyethylene pipes that are urgently needed in my country's pressurized gas pipe and water pipe market (demand exceeds 1 million tons) Materials and additives used to improve its UV resist...
