Embodiment 1

[0025] The radiation-modified polyethylene of the present invention is prepared according to the following method:

[0026] Take 40kg of polyethylene and irradiate it through an electron accelerator. The energy level of the electron accelerator is 3.0MeV, and the irradiation dose is 12KGy. The irradiated polyethylene is mixed with 1kg of ethylene to obtain the product.

Embodiment 2

[0028] The radiation-modified polyethylene of the present invention is prepared according to the following method:

[0029] Take 50kg of polyethylene and irradiate it through an electron accelerator. The energy level of the electron accelerator is 3.0MeV, and the irradiation dose is 25KGy. The irradiated polyethylene is mixed with 1kg of ethylene to obtain the product.

Embodiment 3

[0031] The special cross-linking promotion cross-linking concentrated master batch for cables of the present invention comprises 60 kg of irradiation grafted modified polyethylene, 10 kg of toner, 2 kg of diffusing powder, 0.5 kg of antioxidant, 1 kg of surfactant, 4 kg of cross-linking agent, three Methylolpropane triacrylate 15kg.

[0032] The preparation method of the special crosslinking promotion crosslinking concentrated masterbatch for cables of the present invention comprises the following steps:

[0033] (1) Mix the irradiation-grafted modified polyethylene, toner, diffusion powder, and antioxidant in proportion, and stir for 3 minutes at a stirring speed of 1000 to 1200 r / min to obtain a mixture;

[0034] (2) After raising the temperature of the twin-screw granulator to 130-180°C, the mixture is sent to the twin-screw granulator for extrusion and granulation, wherein the screw temperature of the twin-screw granulator is: the temperature in the first zone is 130- 150...

Abstract

The invention relates to a cross-linking promoting cross-linked concentrate master batch special for a cable and a preparation method. The cross-linking promoting cross-linked concentrate master batchspecial for the cable is prepared from the following components in parts by weight: 60 to 90 parts of irradiation graft modified polyethylene, 10 to 15 parts of toner, 15 to 20 parts of trimethylolpropane triacrylate, 2 to 3 parts of diffusion powder, 0.5 to 1 part of antioxidant, 1 to 2 parts of surfactant, and 4 to 6 parts of cross-linking agent. After the components are mixed evenly, the components are put into a twin screw pelletizer for pelleting. The special cross-linking for the cable promoting the cross-linked concentrate master batch and the preparation method have the beneficial effects that polyethylene powder is irradiated with a 3.0 electron accelerator, irradiation dose is 12 to 25 KGy, pre-irradiated polyethylene powder is obtained, and then a polyethylene monomer is addedto be mix evenly. Pre-irradiation improves hydrophilicity of the polyethylene, a large proportion (20 to 30%) of trifunctional reactive monomer (TMPTA) can be added, the toner and processing aids areadded at the same time, and the cross-linked color master batch special for the cable is produced through a kneading machine, so the problems of difficult cross-linking and coloring in a sheath material of a cable industry can be solved once for all.

Description

technical field [0001] The invention belongs to the field of color masterbatch processing, and in particular relates to a crosslinking-promoting concentrated masterbatch for cables and a preparation method thereof. Background technique [0002] There are three kinds of coloring methods for producing plastic products in the prior art: toner coloring, dyeing and pulling grain coloring and masterbatch coloring. When directly using toner for coloring, the coloring is very simple, but it has the disadvantages of easy to produce color spots, difficult to control color difference, and great environmental pollution. Dyeing Dyeing is to mix plastic raw materials and toner and then use mixing equipment such as twin-screw extruder for melt blending and coloring. Compared with coloring with toner, the coloring effect of granules has been greatly improved, but the plastic It needs to be heated twice, which not only increases the production cost, but also damages the mechanical propertie...
