Embodiment 1

[0012] A method for preparing flame retardant mixed silicone rubber with platinum compound and fumed white carbon black, the method steps are as follows,

[0013] a. Add fumed silica with a specific surface area of ​​50㎡ / g to the platinum acid, mix and place it at room temperature for 10 hours to form a mixture of platinum compound and silica;

[0014] b. Add fumed silica, modifier and iron oxide with a specific surface area of ​​200㎡ / g to methyl vinyl silicone rubber raw rubber with a degree of polymerization of 7000, knead evenly in a kneader, and heat treat at 150°C for 2 Hours, add a mixture of flame retardant additives fumed titanium dioxide and platinum compound and white carbon black, and mix evenly on a two-roll rubber mixer to form a rubber compound.

Abstract

The invention relates to a preparing method of flame-retardant mixed silicone rubber by utilization of a platinum compound and vapor-phase-method white carbon black in combination, and relates to the technical field of rubber products. The preparing method includes: a) a step of adding vapor-phase-method white carbon black having a specific surface area of 50 m<2> / g into chloroplatinic acid, mixing, and allowing the mixture to stand at room temperature for 10 h to obtain a mixture of the platinum compound and the white carbon black; and b) a step of adding vapor-phase-method white carbon black having a specific surface area of 200 m<2> / g, a modifier and ferric oxide into methyl vinyl silicone raw rubber having a polymerization degree of 7000, uniformly mixing in a kneading machine, performing thermal processing at 150 DEG C for 2 h, adding a flame retardant auxiliary agent that is vapor-phase-method titanium dioxide and the mixture of the platinum compound and the white carbon black, and uniformly mixing at a double-roller rubber mixing machine to obtain a rubber material. The components are simple and preparation is convenient. By adding the platinum compound, the mixed silicone rubber is good in performance, free of odor, just right in color and good in flame retardant performance.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a method for preparing flame-retardant and kneaded silicone rubber by using a platinum compound and fumed white carbon black. Background technique [0002] Silicone rubber (English name Silicone rubber) can be divided into thermal vulcanization type (high temperature vulcanization silicone HTV) and room temperature vulcanization type (RTV). Among them, the room temperature vulcanization type is divided into polycondensation reaction type and addition reaction type. High temperature silicone rubber is mainly used to manufacture various silicone rubber products, while room temperature silicone rubber is mainly used as adhesive, potting material or mold. The thermal vulcanization type is used in the largest amount, and the thermal vulcanization type is divided into methyl silicone rubber, methyl vinyl silicone rubber, methyl vinyl phenyl silicone rubber, and other silicone r...
