The invention discloses a marine low-smoke and low-odor rubber-plastic material and a preparation method thereof, and relates to the technical field of marine materials, comprising the following raw materials in parts by weight: 25-35 parts of rubber, 20-30 parts of a foaming agent, and 50 parts of a smoke suppressant. -55 parts, 10-20 parts of filler, 30-40 parts of carbon black, 5-10 parts of silica, 0.5-1.5 parts of stearic acid, 3-8 parts of zinc oxide, 1.0-2.5 parts of antioxidant, montan wax 5-8 parts, paraffin oil 5-10 parts, accelerator 3.1-5 parts, sulfur masterbatch 0.5-1.5 parts, microcapsule red phosphorus 5-18 parts, expanded graphite 5-15 parts and magnesium hydroxide 15-20 parts . The rubber-plastic material of the present invention adopts an environment-friendly foaming agent compounded with inorganic and organic flame retardants, which effectively improves the odor generated by azodicarbonamide as a decomposed product of the foaming agent, and reduces the odor of additives in the rubber-plastic material itself. Thereby, the emission of harmful gases of the rubber and plastic material itself can be reduced; the volatile substances in the product can be further removed by baking, so as to ensure the low volatility and low odor of the prepared rubber and plastic material. |
