Embodiment 1-4

[0029] According to the formula in Table 1, stir the above materials evenly in a star mixer at a temperature of 175°C, add a crosslinking agent after cooling, and extrude to make cables; or, scrape and coat on glass fiber cloth, laminate and heat press into sheets material for making new energy battery cell modules. The test results after combustion of the products prepared in Examples 1-4 are shown in Table 1.

[0030] The fire-proof and fire-resistant cable prepared by the present invention can pass the British fire-resistant cable standard BS6387's 950 ° C × 180 minutes, spray and vibration experiments, can prevent the occurrence of "secondary fire", protect the smooth line of the line in the case of fire, and provide personnel Escape and rescue of property win time.

[0031] The new energy battery cell module prepared by the invention can prevent the fire from spreading when the rechargeable battery is overcharged, and can also play the role of fire blocking, temperature ...

Abstract

The invention discloses fire-resistant polysiloxane composition and application thereof. The composition is prepared from the materials of 100 to 150 parts of polysiloxane base body, 40 to 90 parts of oxide, 0 to 75 parts of phosphoric acid and / or phosphate, 0 to 18 parts of zinc borate, 0 to 1 part of catalyst, 1 to 3 parts of peroxide crosslinking and 0 to 28 parts of reinforcing agent, wherein the catalyst is selected from one of rhodium-containing compound, platinum-containing compound and iridium-containing compound or a mixture of the rhodium-contained compound, the platinum-contained compound and the iridium-contained compound. According to the fire-resistant polysiloxane composition, a production technology is simplified, and energy is remarkably saved; the fire-resistant polysiloxane composition has insulation property, filling property, oxygen insulation property, fire insulation property, thermal insulation property, flame resistance, fireproof property and fire resistance, is mainly applied to new-energy electric vehicles, can remarkably reduce loss of the new-energy electric vehicles on fire, also can be used for manufacturing an insulator or a filling body or an oxygen insulation body or a fireproof body or an inner protection layer of a cable, can be used as a thermal-insulation, fireproof and heat-preservation material of aircrafts, ships, warships, high-speed rails and buildings, and has good application prospect.

Description

technical field [0001] The invention relates to a fire-resistant polymer material, in particular to a fire-resistant and flame-retardant polysiloxane composition, which is used for fire-resistant, flame-retardant, temperature-insulating, heat-insulating, fire-blocking and Cable insulation, fire resistance, flame retardant, temperature insulation, heat insulation, fire protection. Background technique [0002] Existing new energy battery cell modules and cables use rubber, silicone rubber and plastic as the base material. Rubber, silicone rubber and plastic are used as the base material for battery cells. The functions of heat insulation, fire insulation and fire protection cannot prevent the spread of fire. [0003] Therefore, there is an urgent need to develop a material with insulation, filling, oxygen insulation, fire insulation, temperature insulation, flame retardancy, fire prevention, and fire resistance, which is used for new energy battery cell modules and insulatio...
