Abstract

The invention relates to a flame-retardant composite material and a preparation method thereof, relating to the technical field of materials. The composition material comprises the following compositions in parts by mass: 30-50 parts of modified organosilicon resin, 10-20 parts of silicon carbide ceramics, 5-10 parts of forged kaolin, 5-15 parts of molybdenum dibutyldithiocarbamate, 5-10 parts of flame retardant, 3-8 parts of silane coupling agent, 3-6 parts of curing agent and 12-28 parts of water. The flame-retardant composite material is a resin-ceramic flame-retardant material, not only is excellent flame-retardant, but also has better mechanical performance, is excellent in high-temperature-resistant corrosion-resistant and anti-oxidization property, and the flame retardance property of the material can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a flame-retardant composite material and a preparation method of the composite material. Background technique [0002] Flame retardant materials are materials that can inhibit or delay combustion but are not easy to burn themselves. Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. It has the advantages of high melting point, high hardness, high wear resistance and oxidation resistance. Therefore, ceramics are also an excellent flame retardant material. [0003] Resin flame retardant coating material is a material with wide application prospects at present. It can better protect the substrate by using the high temperature resistance and excellent curing performance of the resin. Moreover, adding a proper flame retardant to the resin will have a better flame reta...
