Abstract

The invention relates to a low-temperature ceramic flame-retardant functional master batch. The master batch comprises the following components in parts by mass: 10-25 parts of silicone rubber, 5-15 parts of silicone resin, 2-6 parts of aluminum hypophosphite, 2-10 parts of glass beads, 2-8 parts of montmorillonite, 10-25 parts of natural bone meal, 25-50 parts of synthetic ceramic bone meal, 1-2parts of a coupling agent, 1-3 parts of a lubricant and 1-3 parts of a dispersant. The invention also relates to a preparation method of the low-temperature ceramic flame-retardant functional master batch. The dispersity is improved, the carbon forming rate is increased, and a carbon layer with a multi-dimensional stable structure has a high precipitation rate and integrity rate. The flame-retardant master batch becomes ceramic at a low temperature when the master batch is attacked by flame, can form a continuous and compact ceramic oxygen barrier layer, and has the characteristics of high efficiency and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of polymer synthetic material composition functional masterbatch, and in particular relates to a low-temperature ceramicized flame retardant functional masterbatch and a preparation method thereof. Background technique [0002] The extensive use of polymer materials in industries such as automobiles, electrical appliances, and construction has led to extensive research on the technology of flame-retardant masterbatch products. The flame retardant solves the problem of flame retardant dust pollution through masterbatching, solves the problem of low flame retardant efficiency when powdered flame retardants are used, requires multiple compounding, difficult to disperse flame retardant powder evenly, and affects the mechanical properties of products Bigger problem. Flame retardants improve product stability and production efficiency through masterbatching. Therefore, improving material performance through flame...
