Abstract

The invention relates to a high-flexing low-smoke halogen-free antiflaming sheathing material of an elevator cable, and a preparation method and application thereof. The sheathing material is prepared through the following steps that (1), a vulcanizing agent is dissolved into a silane coupling agent, and a silane coupling agent solution containing the vulcanizing agent is obtained; (2), polyolefin elastomer resin and acrylic ester rubber are mixed to obtain a mixture; (3), the silane coupling agent containing the vulcanizing agent is adsorbed in the mixture obtained in the step (2), and then a mixed material is obtained; and (4), an inorganic flame retardant, an antioxidant and the mixing material obtained in the step (3) are put into an internal mixer together, mixing is conducted for five to ten minutes at the temperature of 120-140 DEG C, then a catalyst is added, banburying is conducted for one to three minutes at the temperature of 120-140 DEG C, and the high-flexing low-smoke halogen-free antiflaming sheathing material is obtained. According to the high-flexing low-smoke halogen-free antiflaming sheathing material of the elevator cable, the preparation method and the application, the sheathing material is high in tensile strength and breaking elongation rate and good in flex fatigue resistant property; the formula and technological operation are easy, and cost is low.

Description

technical field [0001] The invention belongs to the field of elevator cables, and in particular relates to a high-flex, low-smoke, halogen-free, flame-retardant elevator cable sheath material and a preparation method thereof. Background technique [0002] According to the statistics of the General Administration of Quality Supervision, Inspection and Quarantine of China, as of the end of 2010, the total number of elevators in use in China reached 1.628 million units, and the rapid growth rate is about 20% per year. The number of new elevators added each year is more than 300,000, accounting for more than half of the total number of new elevators in the world every year. From this point of view, China is already the largest elevator market in the world. [0003] The special application of elevator cables determines that elevator cables have certain characteristics in the selection of raw materials, such as higher strength and toughness requirements than ordinary wires and cab...
