Abstract

The invention relates to the technical field of rubber products by using a platinum compound and an amine in combination to prepare flame-retardant mixed silicone rubber. The method steps are as follows: firstly, nano-silica and silicon carbide micropowder are added to methyl vinyl silicone rubber, and in a kneader Knead at 150°C for 2 hours, then mix with aniline, titanium dioxide, quartz powder and platinum compound on a two-roller machine to form a compound. The invention has simple components and is easy to prepare. Platinum compounds and specific amines are used together as flame retardant additives to prepare flame retardant mixed silicone rubber. Hydrosilylation vulcanization avoids the problem of coloring usually caused by the combination of platinum compound with carbon black, titanium dioxide and iron oxide and the problem of flame retardancy decrease during storage.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a flame-retardant mixing silicone rubber prepared by using a platinum compound and an amine together and a preparation method thereof. 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 s...
