Embodiment 1～3 and comparative example 1～4

[0032] The present invention provides the raw material ratios of Examples 1-3 and Comparative Examples 1-4 as shown in Table 1 (each component is calculated in parts by weight).

[0033] Table 1 Embodiment 1~3 and comparative example 1~4 raw material proportioning (each component is counted in parts by weight)

[0034]

[0035]

[0036] Among them, polyethylene uses PE100 grade resin, and its melt index is 0.2-0.35g / 10min; carbon black uses 20-25nm furnace carbon black; compatibilizing resin uses cycloolefin copolymer, which is TOPAS 6013 from American Ticona Corporation. Its volume flow index (260°C / 2.16kg) is 12-15mL / 10min; titanium dioxide is selected as an oily rutile nano-titanium dioxide dispersion with a solid content of 30%; zinc oxide is an oily nano-zinc oxide liquid with a solid content of 25%; The dispersant is polyethylene wax 617A; the antioxidant is made of hindered phenolic antioxidant 1010 and phosphite antioxidant 168 according to the mass ratio of 1:1;...

Embodiment 4

[0052] An embodiment of the color masterbatch of the present invention, the proportion and preparation method of the color masterbatch described in this embodiment are the same as those in Example 1. The polyethylene uses PE100 grade resin, and its melt index is 0.2-0.35g / 10min; the carbon black uses 20-25nm furnace carbon black; The flow index (260°C / 2.16kg) is 12-15mL / 10min; the titanium dioxide is selected as an oily rutile nano-titanium dioxide dispersion with a solid content of 30%; the zinc oxide is an oily nano-zinc oxide liquid with a solid content of 25%. The difference is:

[0053] The dispersant used in this example is fatty acid ester wax; the antioxidant is made of hindered phenolic antioxidant 1010 and phosphite antioxidant 168 at a mass ratio of 2:1; the carbon nanotubes are double-walled carbon nanotubes; dimethylamine is selected as the blocking cross-linking agent.

Embodiment 5

[0055] An embodiment of the color masterbatch of the present invention, the proportion and preparation method of the color masterbatch described in this embodiment are the same as those in Example 1. The polyethylene uses PE100 grade resin, and its melt index is 0.2-0.35g / 10min; the carbon black uses 20-25nm furnace carbon black; The flow index (260°C / 2.16kg) is 12-15mL / 10min; the titanium dioxide is selected as an oily rutile nano-titanium dioxide dispersion with a solid content of 30%; the zinc oxide is an oily nano-zinc oxide liquid with a solid content of 25%. The difference is:

[0056] The dispersant in this example is made of barium stearate, zinc stearate, magnesium stearate and calcium stearate in a mass ratio of 1:1:1:1; the antioxidant is hindered phenolic antioxidant Antioxidant 1010 and phosphite antioxidant 168 are compounded at a mass ratio of 2:1; carbon nanotubes are a mixture of single-walled carbon nanotubes and double-walled carbon nanotubes at a ratio of ...

Abstract

The invention discloses a special color master batch for a polyethylene water supply pipe, a preparation method and applications thereof, wherein the special color master batch is prepared from the following components in parts by weight: 40-80 parts of a carrier resin, 2-25 parts of a compatibilizing resin, 28-55 parts of carbon black, 2-15 parts of a dispersing agent, 1-3 parts of an antioxidant, 0.05-0.2 part of carbon nanotubes, 0.01-2 parts of titanium dioxide, 0.01-2 parts of zinc oxide and 0.2-1.5 parts of a cross-linking inhibitor. According to the invention, four toner systems are utilized to blend carbon black masterbatch into black, and the formula of a PE water supply pipe color master batch is effectively improved, so that the laser marking definition of the PE water supply pipe can be effectively improved, the edge definition is improved, the obtained product is attractive, and the defects generated by laser marking of the carbon black color master batch in PE water supply pipe production application are effectively overcome; and the color master batch has good compatibility with pipe raw materials, can reduce scratches, line hanging and other undesirable phenomena, and has good surface smoothness.

Description

technical field [0001] The invention belongs to the technical field of water supply plastic pipe coloring. More specifically, it relates to a special color masterbatch for polyethylene water supply pipes and its preparation method and application. Background technique [0002] Polyethylene (PE) is a thermoplastic.
