Transparent flame-retardant silicone rubber and preparation method thereof

The invention discloses transparent flame-retardant silicone rubber which is prepared from the following materials in parts by weight: 100 parts of silicone rubber, 0.5-4 parts of a platinum catalyst and 0.05-2 parts of a flame-retardant synergist, and the flame-retardant synergist is prepared from the following materials in parts by weight: 100 parts of basic silicone rubber and 0.5-6 parts of a flame-retardant material. The transparent flame-retardant silicone rubber disclosed by the invention has relatively good flame-retardant property, and can keep excellent mechanical properties and relatively good light transmittance at the same time. The invention also provides a preparation method of the transparent flame-retardant silicone rubber. 本发明公开了一种透明阻燃硅橡胶，按重量份数计，制备材料包括：100份的硅橡胶、0.5～4份的铂金催化剂和0.05～2份的阻燃协同剂，阻燃协同剂的制备材料包括100份的基础硅橡胶和0.5～6份的阻燃材料。本发明的透明阻燃硅橡胶具有较好阻燃性能的同时能保持优异的力学性能和较好的透光率。本发明还提供一种透明阻燃硅橡胶的制备方法。
