Description
Technical Field
The invention relates to the technical field of high polymer material blending flame-retardant cable materials and preparation thereof, in particular to a high-temperature-resistant flame-retardant organic silicon elastomer cable material and a preparation method thereof.
Background
The demand of the market for electric wires and cables is increasing, and the physical and chemical (physical and chemical) performance of the photoelectric cables is also becoming more and more severe, so that the development of electric wire and cable materials is accelerated, and new materials for photoelectric cables with excellent technical effects are being continuously promoted, for example, thermoplastic elastomers have processability of plastics and high elasticity of rubber and can be recycled, so that the thermoplastic elastomers are generally accepted and paid great priority in the industry as the later-living people.
Thermoplastic elastomers currently used in the field of photoelectric cable materials mainly include polyolefin thermoplastic elastomers (TPO), styrene thermoplastic elastomers (TPS), polyurethane thermoplastic elastomers (TPU), and various thermoplastic dynamic vulcanizates (TPV). TPOs include conventional ethylene-octene copolymers (POEs) and ethylene-vinyl acetate copolymers (EVA) and the like, which have relatively low melting points and are commonly used to make thermoplastic cable materials having relatively low temperature ratings (< 90 ℃); hydrogenated styrene elastomers such as SEBS and SEPS are mostly used for TPS, and the TPS has excellent heat resistance and weather resistance but poor oil resistance; although the TPU has excellent chemical resistance and good oil resistance, the TPU has poor heat resistance and high-temperature water resistance, the processing temperature range is narrow, and the use of the TPU is limited due to higher cost; TPV is prepared by dispersing fully vulcanized rubber particles (EPDM) in a Plastic Phase (PP), and has obviously improved thermal aging resistance and oil resistance compared with polyolefin, but has general processing performance and flow marks on the surface.
In view of the market's great demand for high-temperature-resistant flame-retardant elastomer cable materials, such as some exported American standard power cords, and also in recent years, in the rapidly-developing new energy automobile industry, the corresponding American standard electric automobile charging pile cable has high requirements for mineral oil resistance, high-temperature heat resistance and flame retardancy of the sheath material, and in view of the fact that the existing thermoplastic elastomer cable material cannot completely meet the requirements.
The organosilicon material has high and low temperature resistance, lower glass transition temperature (Tg), surface tension and viscosity-temperature coefficient, excellent electrical property, air permeability and biocompatibility, and is incomparable and replaceable with other organic polymer materials, thereby drawing wide attention. At present, along with the expansion of the capacity of the organic silicon monomer, the production cost of the organic silicon product is continuously reduced; meanwhile, as the price of petroleum products changes, the price difference between the two is gradually shrinking. Therefore, the global energy source has been increasingly fluctuated, and a huge development space is provided for the organic silicon material.
The organic silicon polymer is organic siloxane (Si), wherein the silicone resin and the silicone rubber have the characteristics of hydrophobicity, moisture resistance, high and low temperature resistance, electric insulation, aging resistance and the like. The industrial elastomer Ethylene Propylene Diene Monomer (EPDM), Styrene Butadiene Rubber (SBR), Thermoplastic Polyurethane (TPU) and the like have poor water resistance or oil resistance, the elongation at break of the elastomer is 100-700%, and the organic silicon elastomer has a functional group capable of absorbing polar and oily grease, plays a crucial role in linkage in blending, has excellent compatibility, can reduce the viscosity in a formula, enables a product to be smoother and not sticky, and simultaneously has super-strong mechanical properties, and the elongation at break of 100-1000%.
Therefore, the organic silicon resin of the multifunctional polysiloxane is selected as the main base material, the compatibility is good in a composite material system, the excellent mechanical property is kept, the polar material with excellent performance is added to modify the organic silicon resin, the problem of poor compatibility between the main base material and the modified base material is solved by adding the compatilizer, and on the basis, the organic silicon elastomer cable material with excellent processing performance, flame retardance, heat resistance and mechanical property is prepared by selecting a proper flame retardant, so that the organic silicon elastomer cable material has positive significance, and the technical scheme to be introduced is generated under the background.

TABLE 1
| Oxygen index/% | Thermal deformation/%) | Drip resistance | Elongation at break/% | |
| Example 1 | 36 | 2.89 | Without dripping | 153 |

In comparative example 1, due to the addition of the additive flame retardant, the influence on the mechanical properties of the material is great, so that the elongation at break is low; comparative example 2, which is superior in mechanical properties, is low in flame retardancy due to a sharp decrease in the additive flame retardant; comparative example 5, as the silicone resin content increased, the reaction flame retardant and the high temperature resistant flame retardant decreased, resulting in a decrease in mechanical and thermal properties. The above results show that in example 3, the optimal performance index is achieved by the mutual matching ratio of the raw materials, a better effect is achieved, and the thermal property, the flame retardant property and the mechanical property of the cable can be improved.
