Abstract

The invention relates to a halogen-free environment-friendly high-speed elevator compensation chain material. The material comprises the following raw materials in parts by weight: 40-60 parts of ethylene-propylene diene copolymer, 20-40 parts of ethylene-octene copolymer, 10-30 parts of maleic hydride grafted ethylene-vinyl acetate copolymer and / or maleic hydride grafted ethylene-octylene copolymer with shore A hardness of 65-85, 250-450 parts of high-density packing, 15-25 parts of epoxidized soybean oil, 1-2 parts of antioxidant and 2-5 parts of lubricant, wherein the ethylene content in the ethylene-propylene diene copolymer is 60-70 percent by weight, the content of the third monomer is 2-10 percent by weight, and the mooney viscosity is 20-60. The material can be used together with halogen-free high-speed elevator sheathing material, so that the halogen-free environment-friendly requirement of the whole elevator system can be met; and compared with a traditional elevator balance chain, an elevator balance chain produced by the chain material is lower in cost.

Description

technical field [0001] The invention relates to a high-speed elevator balance compensation chain material. Background technique [0002] At present, the elevator balance compensation chains on the market mainly include rope-threaded compensation chains, plastic-coated compensation chains and all-plastic compensation chains. Among them, the all-plastic compensation chains can be used for high-speed elevators up to 6m / s. The appearance is a cable-like PVC structure, and the elevator runs when in use. It can achieve a smooth and quiet effect, and is favored by many large elevator companies, among which there are specific requirements for the PVC structural material. However, there is no related report about the preparation process of the material used in the PVC structure in the prior art. In addition, PVC structural materials do not meet the requirements of halogen-free environmental protection, and are not suitable for elevator systems that require halogen-free environmental...
