The invention discloses alcohol type colorful transparent liquid silicone rubber and a preparation method and application thereof. The alcohol type colorful transparent liquid silicone rubber comprises the following raw materials in percentages by weight: 60-90% of alkoxyl terminated polydimethylsiloxane, 6-10% of a reinforcing filler, 1.6-6% of a silane coupling agent, 0.3-1% of an organic tin catalyst, 0.01-0.5% of a platinum catalyst, 0.3-1.6% of a tackifier, 1-13% of a hydroxyl scavenger, 0.1-1% of a water removing agent, 1-3% of an inhibitor and 0.5-3% of a coloring agent. The prepared alcohol type colorful transparent liquid silicone rubber is rapid in adhesion removing, high in formation initial strength and good in transparency, cannot become yellow easily, and is short in surfacedrying and adhesion removing time, rapid in solidification and good in mechanical property, and the storage stability is greatly improved. 本发明公开了种醇型彩色透明液体硅橡胶及其制备方法和应用，包括下述重量百分比的原料：烷氧基封端聚二甲基硅氧烷60-90％；补强填料6-10％；硅烷偶联剂1.6-6％；催化剂：
