Problems solved by technology

However, due to the poor dispersion performance (difficult to disperse uniformly) of inorganic flame retardants zinc hydroxystannate (ZHS) and zinc stannate (ZS) in polymer composite materials, their flame retardant performance has been greatly limited. Difficult to be fully released
At the same time, due to the poor interfacial compatibility between zinc hydroxystannate (ZHS) and zinc stannate (ZS) and organic polymer materials, there are problems of difficult dispersion and uneven dispersion in polymer materials, and these two problems Both will affect the performance of the polymer material itself, such as the mechanical properties, tensile strength and toughness of the polymer material will be significantly reduced
[0004] In addition, the existing flame-retardant and smoke-suppressing polymer composite materials still have disadvantages such as complex preparation process, large amount of flame-retardant and smoke-suppressing agent, low flame-retardant and smoke-suppressing efficiency, and significantly worse mechanical properties and decorative effects of the material.

Description

technical field [0001] The invention belongs to the technical field of polymer flame-retardant materials, in particular to a flame-retardant and smoke-suppressing polymer composite material and a preparation method thereof. Background technique [0002] Polymer materials are long-chain molecules composed of repeating units, and together with steel, wood and cement, are considered to be new materials that promote social development. Polymer materials have the characteristics of ease of processing, flexibility, fatigue resistance, light weight, low production cost, high dielectric constant and mechanical strength, etc., and are widely used in aerospace, electronics, biomedicine and automotive industries. The polymer material is flammable and has a fire hazard. Flame retardants can impart self-extinguishing, flame retardant and smoke suppression properties to synthetic materials, so they have become one of the important auxiliaries for the development and application of polyme...
