Mouse-preventing termite-proof halogen-free flame-retarding environment-friendly low smoke cable for electric lift control

Abstract

The invention relates to an anti-rat and anti-termite halogen-free low smoke resistance fire-retardant environmental protection elevator control trailing cable, which consists of ethane-acid ethane multipolymer, ethane-caprylene multipolymer, Al(OH)3, Mg(OH)2, hydroxybenzene antioxidizer, capsaicim environmental-protection anti-rat substance, cypermethrin low-toxic anti-termite agent compound, silane coupling agent 693, peroxide cross linking agent DCP, and polythene wax lubricant. The invention has the advantages that all physical and chemical performance indexes and electric performance indexes conform to supplementary stipulation requirements of GB5023-1997 and CNCA-01C-002:2001 / A1, and the invention has the reliable mechanic performance, excellent fire-retardant performance, better halogen-free low-smoke low-toxic feature, convenient production of single flat cable and twisted flat cable, convenient reclamation and treatment of rejected products, and the anti-rat and anti-termite property.

Description

technical field [0001] The invention relates to an elevator control follow-up cable, in particular to the material properties of the follow-up cable sheath. Background technique [0002] After more than 20 years of reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved, especially in recent years, the construction industry has developed rapidly, and the living conditions of urban residents have been greatly improved; on the other hand , my country's basic national conditions of more people and less land is an objective reality, which prompts urban buildings to develop to high-rise buildings, and these factors have led to an increase in the use of elevators in the construction industry. The use of elevators has brought great convenience to the travel and life of residents, and at the same time, the safe use of elevators is even more important; the elevator control follow-up cable is used as the transmission ...

AI Technical Summary

Problems solved by technology

[0006] 1. The material of the cable sheath is hard, the elasticity is not good, and the bending performance is poor;

[0007] 2. At present, only single-core flat cables can be produced, and multi-core twisted flat cables cannot be produced;

[0008] 3. The life of the cable bending test is low;

[0009] 4. The cable has no anti-termite and anti-rat characteristics;
