Sepiolite-based flame-retardant composite material as well as preparation method and application thereof
The sepiolite-based flame-retardant composite material is prepared from the following components in parts by mass: 100 parts of raw rubber, 6 to 8 parts of an accelerant, 1 to 3 parts of an anti-aging agent, 5 to 6 parts of a vulcanizing activator, 60 to 77 parts of a reinforcing agent, 24 to 40 parts of an intumescent flame-retardant system, 50 to 70 parts of a flame-retardant synergist and 20 to 40 parts of an ionic liquid modified sepiolite material, the raw rubber is a mixture of butadiene styrene rubber and natural rubber; the intumescent flame-retardant system is formed by taking an acid source as a charring catalyst, a carbon source as a carbonizing agent of the intumescent flame-retardant system and a gas source as an intumescent foaming agent of the intumescent flame-retardant system; the reinforcing agent is a mixture of white carbon black and carbon black; the flame retardant synergist is a mixture of hydrotalcite and aluminum hydroxide; the ionic liquid modified sepiolite material is used as a reinforcing agent and the flame retardant synergist to improve the flame retardant property and mechanical property of the composite material. The styrene butadiene rubber flame-retardant system is constructed by adopting an ionic liquid modified sepiolite nanofiber composite intumescent flame-retardant synergistic system. Due to rich silicon hydroxyl groups on the surface of the sepiolite, the dispersity of the sepiolite in styrene butadiene rubber is poor, so that the mechanical property of the sepiolite is greatly reduced, and in order to meet the mechanical property of the rubber waterstop, the ionic liquid modified sepiolite is compounded with an intumescent flame-retardant synergistic system; the flame retardant property of the styrene-butadiene rubber is effectively improved; the loss of mechanical properties is reduced to the greatest extent.
本发明公开的海泡石基阻燃复合材料，以质量份数计包含以下组分：100份生胶，6‑8份促进剂，1‑3份防老剂，5‑6份硫化活性剂，60‑77份补强剂，24‑40份膨胀阻燃体系，50‑70份阻燃协效剂和20‑40份离子液体改性海泡石材料；所述生胶为丁苯橡胶和天然橡胶混合；所述膨胀阻燃体系由酸源作为成炭催化剂、碳源作为膨胀阻燃体系的炭化剂和气源作为膨胀阻燃体系的膨胀发泡剂构成；所述补强剂为白炭黑和炭黑的混合；所述阻燃协效剂为水滑石和氢氧化铝的混合；所述离子液体改性海泡石材料作为补强剂和所述阻燃协效剂以提高复合材料的阻燃性能和力学性能。采用离子液体改性海泡石纳米纤维复合膨胀阻燃协效体系构建丁苯橡胶阻燃体系。由于海泡石表面丰富的硅羟基，导致其在丁苯橡胶中的分散性差，从而使其力学性能大幅度降低，为满足橡胶止水带的力学性能，采用离子液体改性海泡石与膨胀阻燃协效体系复配，有效提高丁苯橡胶的阻燃性能和最大程度降低力学性能的损耗。
