Abstract

The invention relates to a low-temperature ceramic flame-retardant functional masterbatch, which comprises the following components by mass: 10-25 parts of silicone rubber, 5-15 parts of silicone resin, 2-6 parts of aluminum hypophosphite, and 2-10 parts of glass microspheres 2-8 parts of montmorillonite, 10-25 parts of natural bone powder, 25-50 parts of synthetic ceramic bone powder, 1-2 parts of coupling agent, 1-3 parts of lubricant and 1-3 parts of dispersing agent. The invention also relates to a method for preparing low-temperature ceramicized flame retardant functional masterbatch, which improves the dispersibility and increases the carbon formation rate, so that the carbon layer with a multi-dimensional stable structure has a high precipitation rate and integrity rate. The flame retardant masterbatch prepared by the invention can be ceramicized at low temperature when the material encounters flame attack, and can form a continuous and dense ceramic oxygen barrier layer, which has the characteristics of high efficiency and environmental protection.

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...
