Embodiment

[0031] 1. Experimental materials

[0032] The composition and proportioning of raw materials are shown in Table 1 below.

[0033] EVA resin was purchased from Formosa Plastics; silicone acrylate copolymer was purchased from Dow Corning; aluminum hydroxide was purchased from Chalco; magnesium hydroxide was purchased from Dandong Xinyang; flame retardant synergist was purchased from Clariant; antioxidant Purchased from BASF; lubricants purchased from Shanghai Gaoqiao Petrochemical.

[0034] 2. Experimental method

[0035] 1) Put the EVA resin, flame retardant, lubricant, and antioxidant in a high-speed kneader for low-speed mixing, and at the same time, add the silicone acrylate in two to three times, and start high-speed mixing after it is completely added;

[0036] 2) After high-speed mixing until uniform, start low-speed mixing again. In the case of low-speed mixing, first add a flame retardant synergist and mix evenly to obtain a mixture;

[0037] 3) The homogeneously mix...

Abstract

The invention discloses a special constant-temperature constant-humidity flame-retardant halogen-free cable material used for five cables and not prone to discoloring. The cable material is characterized by comprising the following components in parts by weight: 50-100 parts of EVA resin, 50 to 100 parts of a flame retardant, 20 to 40 parts of an organosilicon acrylate copolymer, 10 to 30 parts ofa flame retardant synergist, 0.5 to 4 parts of a lubricant and 0.1-2 parts of antioxidant. The invention also discloses a preparation method of the cable material. According to the cable material inthe invention, common materials of traditional cable materials are improved, and the problems that the common materials are large in mechanical property loss and prone to yellowing and discoloring indamp and heat resistance tests at a temperature of 85 DEG C and a relative humidity of 85% are mainly solved, so the cable material meets various requirements for environmental protection, flame retardance and damp-heat resistance.

Description

technical field [0001] The invention relates to the technical field of cable material manufacture, in particular to a flame-retardant halogen-free cable material specially used for five types of cables with constant temperature and humidity and not easy to change color, and a preparation method thereof. Background technique [0002] In recent years, with the development of the world economy and technology, the demand for Category 5 cables (that is, Category 5 lines) is increasing, and the performance requirements are increasing. Under the new economic situation and technical conditions, the development of the global wire and cable industry presents a new trend, and environmentally friendly cables have gradually become the focus of global cable development. At the same time, due to the various environments in which the cables are used, the requirements for moisture and heat resistance are put forward for the cables. In view of these actual use requirements, it is necessary t...
