Abstract

The invention relates to a nano high-efficiency catalytic flame-retardant functional master batch which comprises the following components in parts by weight: 5-15 parts of nano catalytic carbon-forming agent pre-dispersed slurry, 75-90 parts of a carrier and 5-10 parts of a functional aid. The nano catalytic carbon-forming agent pre-dispersion slurry comprises a dispersion solvent, a stabilizer and a nano catalytic carbon-forming agent. The mass ratio of the dispersing solvent to the stabilizer to the nano catalytic carbon-forming agent is (60-80):(10-20):(2-5). The invention also relates to a preparation method of the functional master batch, which comprises the following steps: preparing the nano catalytic carbon-forming agent pre-dispersed slurry and the functional additive, mixing the nano catalytic carbon-forming agent pre-dispersed slurry and the functional additive with the carrier, and extruding a formed mixture. The method is suitable for a large-scale production process, and a good catalytic flame-retardant effect is achieved.

Description

technical field [0001] The invention relates to the field of flame-retardant functional masterbatch and its preparation, in particular to a nanometer high-efficiency catalytic flame-retardant functional masterbatch and a preparation method thereof. Background technique [0002] Plastic products have excellent mechanical properties, chemical corrosion resistance, etc., and are widely used in various fields such as electrical appliances, furniture, and pipes. However, plastic burning products are flammable, and are extremely likely to produce smoke and toxic gases that are more harmful to people. With the continuous improvement of people's awareness of fire prevention and the continuous improvement of national laws and regulations, flame-retardant plastics are gradually becoming popular. Halogen-based flame-retardant materials were mostly used for early flame retardants, but halogen-based flame retardants produce hydrogen halide gas during combustion, which has a certain impa...
