Embodiment 1

[0014] A platinum compound combined with carbon black to formulate a flame retardant rubber compound consisting of components by weight of,

[0015]

[0016]

[0017] The platinum compound is chloroplatinic acid.

[0018] Its method steps are as follows,

[0019] a. Add fumed silica and dimethylcyclosiloxane to natural rubber, knead evenly in a kneader, treat at 140-170°C for 1-4 hours, then add platinum compound and mix well, Formulated with glue;

[0020] b. Mix the rubber material with carbon black, ammonia water, tung oil and compound phosphate on a double-roller rubber mixer to make a flame-retardant mixed silicone rubber.

Abstract

The invention provides a flame retardant mixed silicone rubber prepared by simultaneous using the platinum compound and carbon black and relates to the technical field of rubber products. The flame retardant mixed silicone rubber comprises the following components in parts by weight: 40-100 parts of natural rubber, 10-30 parts of fumed silica, 0.5-10 parts of dimethyl cyclosiloxane, 20-60 parts of the platinum compound, 1-5 parts of carbon black, 0.5-3 parts of ammonia water, 0.5-1 part of China wood oil and 0.1-0.5 part of complex phosphate. The flame retardant mixed silicone rubber provided by the invention is simple in components and convenient to prepare; through adding the platinum compound, the complex phosphate, the ammonia water and other components, the prepared mixed silicone rubber is good in performances, inodorous, pure in color and favorable in flame retardant property.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a flame-retardant mixed rubber prepared by using a platinum compound and carbon black together. Background technique [0002] Silicone rubber (English name Siliconerubber) is divided into heat 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 rubber and fluorosilicone rubber.
