Problems solved by technology

[0002] Silicone rubber has good high and low temperature resistance, and is widely used in cable products. However, the existing silicone rubber has poor flame retardancy, and it is easy to burn during the mixing and extrusion process of the rubber material. Rubber extrusion vulcanization production line, because the production line uses ice water cooling and hot air vulcanization, it is expensive, not only high cost, but also low efficiency

Embodiment 1

[0007] Example 1: The composition in component A selects 100 parts by weight of methyl vinyl silicone rubber, 40 parts of fumed white carbon black, 2 parts of methylphenyldiethoxysilane, 10 parts of red phosphorus, 5 parts of phosphoric acid triester TCEP; 3 parts of bis-tert-butylperoxyhexane DBQD and 22 parts of m-phenylene bismaleimide HVA in component B. First mix the material of component A at a temperature of 50-70°C for 5-7 minutes until the components are uniformly dispersed, then add the material of component B and mix for 2-3 minutes to obtain a silicone rubber composition. The silicone rubber composition is cross-linked It is processed and produced by a steam sulfuration unit, the vulcanization steam pressure is 13-15MPa, the vulcanization pipeline temperature is 170-200°C, and the vulcanization time is 2-4min.

Abstract

The invention relates to a steam vulcanization inflaming retarding silicon rubber and a processing method thereof. The product is formed by mixing component A and component B, wherein the component A comprises methyl vinyl silicone rubber, gas phase method white carbon black, methyl phenyl diethoxy silane, red phosphorus and phosphotriester (TCEP) according to a certain proportion; and the component B comprises bis-t-butylperoxy hexane (DBQD) and meta-phenylene bis-maleimide HVA-2. The methyl vinyl silicone rubber is taken as main base material and peroxide as vulcanizing agent, so that composition can be formed by crosslinking in high temperature steam, thus having soft material quality and good flame retardant property. Furthermore, the steam vulcanization inflaming retarding silicon rubber has good properties of ozone resistance, low temperature resistance and heat aging resistance, so as to be especially suitable for manufacturing inflaming retarding silicon rubber power cables, wind energy cables and the like. By adopting a common steam continuous machine unit for processing and producing, the production is convenient, and the cost is low.

Description

technical field [0001] The invention relates to a rubber product and a production process thereof, in particular to a steam vulcanized flame-retardant silicone rubber and a processing method thereof. Background technique [0002] Silicone rubber has good high and low temperature resistance, and is widely used in cable products. However, the existing silicone rubber has poor flame retardancy, and it is easy to burn during the mixing and extrusion process of the rubber material. Rubber extrusion vulcanization production line, because the production line adopts ice water cooling and hot air vulcanization, the price is expensive, not only the cost is high, but also the efficiency is low. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide a kind of steam-vulcanized flame-retardant silicone rubber with good flame retardancy, ozone resistance, low temperature resistance, heat aging r...
