Weather-proof environment-friendly flame-retardant polymer material for flexible cable and preparation method thereof

Abstract

The invention discloses a weather-proof environment-friendly flame-retardant polymer material for a flexible cable and a preparation method thereof. The polymer material comprises the following components by weight: 100 parts of a component A, 20 to 200 parts of a component B and 50 to 130 parts of a component C, wherein the component A is TPE, the component B is TPV, the component C is a fire retardant and comprises C1 and C2, C1 is one selected from the group consisting of decabromodiphenylethane, 1,2-bis(tribromophenoxy)ethane, tetrabromobisphenol A, tetrabromo-benzene anhydride, octabromo-ether, bis(tetrabromo-o-benzene-dimethyl ether imide)ethane and hexabromocyclododecane and has a particle size in a range of 10 to 30 mu m, and C2 is one selected from the group consisting of antimony trioxide, zinc borate and zinc oxide. The polymer material provided by the invention has improved processing performance and tensile strength, high usage temperature and excellent weatherability, environmental protection performance and flame resistance and is especially applicable to outdoor usage in a severe environment.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a weather-resistant, environment-friendly, flame-retardant polymer material for flexible cables and a preparation method thereof. Background technique [0002] At present, wires and cables are widely used for the transmission of energy and information. The insulation layer or sheath of wires and cables made of traditional polymer materials is easy to burn due to excessive heat generation or short circuit during use, causing Fire, the European Union, the United States and many other regions have also imposed restrictions on heavy metals and biphenyl compounds in electrical appliances and wire products. [0003] Traditional flame retardant polymers have limitations, and the more mature flame retardant systems are as follows: [0004] (1) Traditional halogen and antimony compound system. The disadvantage is that when the halogen flame retardant is burned, it will release dioxins, ...

AI Technical Summary

Problems solved by technology

In the traditional flexible family, PVC has the highest occupancy rate, but it is plagued by problems such as halogens and plasticizers. EVA is also a common flexible material, but its biggest problems are: low tensile strength, low operating temperature, etc. question

However, the surface of this kind of flame retardant material products has a strong greasy feeling, and the inkjet fastness is low
