preparation example Construction

[0055] The second aspect of the present invention provides a preparation method of the 125°C irradiation crosslinking halogen-free low-smoke flame-retardant oil-resistant and cold-resistant cable material of the present invention. The preparation method includes the following steps:

[0056]1) Put the formula amount of methyl vinyl silicone rubber and base resin A into the mixer, and mix for 3-4 minutes;

[0057] 2) Put all the remaining ingredients into the mixer, and continue banburying together with the methyl vinyl silicone rubber and base resin A put in before for 5-6 minutes. The whole mixing process takes 8-10 minutes Minutes to get a good semi-finished product;

[0058] 3) The semi-finished product that has been banburyed is granulated through a double-cone feeding device, a twin-screw extruder, and a single-screw extruder to obtain the 125°C irradiation cross-linked halogen-free, low-smoke, flame-retardant, oil-resistant, and cold-resistant cable material; The temper...

Abstract

The invention provides a 125 DEG C radiation-crosslinked, halogen-free, low-smoke, flame-retardant oil-resistant and cold-resistant cable material and a preparation method thereof. The cable materialcomprises the following components in parts by weight: 65 parts of base resin A, 35 parts of base resin B, 12-17 parts of a compatilizer, 150-190 parts of a flame retardant, 15-25 parts of methyl vinyl silicone rubber, 0.8-1.6 parts of an antioxidant, 0.4-0.8 part of a lubricant, 1.4-3 parts of a coupling agent, 15-20 parts of a reinforcing agent and 0.4-1 part of a crosslinking agent, wherein thebase resin A is a combination of ethylene-vinyl acetate (EVA) and a polyolefin elastomer (POE); the base resin B is a combination of the ethylene-vinyl acetate (EVA) and linear low-density polyethylene (LLDPE). The cable material provided by the invention has the characteristics of good temperature resistance, oil and cold resistance, aging resistance, superior mechanical properties and the like.The invention further provides the preparation method of the cable material.

Description

technical field [0001] The invention relates to a 125°C irradiation cross-linked halogen-free low-smoke flame-retardant cable material and a preparation method thereof, more specifically to a 125°C irradiation cross-linked halogen-free low-smoke flame-retardant oil-resistant cold-resistant cable material and a preparation method thereof. Background technique [0002] With the rapid development of rail transit, automobile industry, communication, electronic equipment and electrical appliances, the demand for radiation cross-linked halogen-free low-smoke flame-retardant cable materials is increasing day by day, especially for radiation cross-linked cables with a temperature resistance of 125°C The demand is increasing day by day. [0003] In rail transit, automobile industry and some special fields, the oil and cold resistance of cable materials are required to be higher. Although the conventional heat-resistant grade 125°C radiation cross-linked cable material can meet the b...
