Example Embodiment

[0025] Example 1

[0026] A processing method of soft and environment-friendly polyolefin cable material, such as figure 1 As shown, weigh polyolefin powder and silane according to the formula, mix them evenly as modifier, add modifier, flame retardant, and flame retardant synergist into the high-speed mixer, and stir at high speed at 40~45℃ Surface activation treatment is carried out for 20-25 minutes; other components are weighed according to the formula, and the modified flame retardant and flame-retardant synergist are mixed together in the mixer at low speed for 3 to 5 minutes; In the twin-screw extruder of the feeding system, plasticizing, extruding, granulating, and packaging are all that is needed. Among them, the temperature of each zone of the screw is between 120-145°C. The product formula (number of copies) is shown in Table 1.

Abstract

The invention discloses a flexible environment-friendly polyolefin cable material and a preparation method of the flexible environment-friendly polyolefin cable material. The flexible environment-friendly polyolefin cable material is prepared from the following components in following parts by weight: 65 to 85 parts of EVA (ethylene vinyl acetate), 15 to 35 parts of POE (polyolefin elastomer), 70 to 130 parts of inorganic flame retardant agent, 10 to 30 parts of flame retardant adjuvant, 5 to 8 parts of modifier, 8 to 13 parts of compatilizer, 1.5 to 2.5 parts of antioxidant, and 3 to 5 parts of lubricant. A flexible thermoplastic elastomer is used as a matrix resin, and a certain proportion of flame retardant adjuvant is added, so on the premise of not affecting the flame retardant property of the cable material, the adding quantity of the inorganic flame retardant agent is greatly reduced, and then the flexible environment-friendly polyolefin cable material is prepared. The flexible environment-friendly polyolefin cable material has the advantages that the flexibility is high, the mechanical property is high, and the flexible environment-friendly polyolefin cable material is suitable for the industries with higher requirements on the flexibility of cables, such as communication cables and weak current cables.

Description

technical field [0001] The invention relates to a cable material, in particular to a soft and environment-friendly polyolefin cable material and a preparation method thereof. Background technique [0002] With the rapid growth of wire and cable applications and rapid economic development, people's requirements for the performance of cable materials are constantly improving, especially in the communication industry and the weak current industry, which have higher requirements for the softness of cable materials. Most of the existing conventional polyolefin cable materials are added with polyethylene with high hardness, and in order to meet certain flame retardant requirements, a large amount of inorganic flame retardants are added, which further increases the hardness of cable materials, thus greatly limiting the It is used in the fields of video lines, audio lines, communication cables, etc.; at present, soft polyvinyl chloride wires and cables emit a large amount of smoke a...
