Flame-retardant automotive plastic uptake material containing mesoporous molecular sieve-graphene and preparation method of automotive plastic uptake material

Abstract

The invention discloses a flame-retardant automotive plastic uptake material containing mesoporous molecular sieve-graphene and a preparation process of the automotive plastic uptake material. The automotive plastic uptake material is characterized by being prepared from acrylonitrile butadiene styrene copolymer (ABS), linear novolac resin, microcapsule red phosphorus, basic magnesium sulfate whiskers, nitrile rubber, a mesoporous molecular sieve SBA-15, ammonium polyphosphate, melamine formaldehyde resin, kaolin, Sb2O3, dimethyl silicone oil, graphene and the like. The mesoporous molecular sieve and the linear novolac resin generate a keyed joint effect, so that the thermal stability of matrix resin is improved; microencapsulated ammonium polyphosphate and antimony oxide/kaolin composite flame-retardant micropowder generate a synergistic effect, so that the flame retardance is relatively good; by adding graphene into the ABS resin matrix, the flame retardance and the thermal stability of the resin are obviously improved, and the mechanical property of the resin is relatively high; and the flame-retardant heat-resisting automotive plastic uptake material containing mesoporous molecular sieve-graphene is obtained.

Description

technical field [0001] The invention relates to the technical field of flame-retardant composite materials, in particular to a flame-retardant automobile plastic-absorbing material containing mesoporous molecular sieve-graphene, and a preparation process thereof. Background technique [0002] ABS is a terpolymer composed of acrylonitrile, butadiene and styrene. As a thermoplastic engineering plastic, it is widely used in the automotive industry, electronics, Electrical appliances, textiles, appliances and building materials and other fields. However, the flame retardancy of ABS resin is poor. How to find an additive that can improve the flame retardancy of ABS resin without reducing its excellent performance has become a research hotspot. [0003] Yang Bing used low-toxicity, low-smoke, high temperature resistance, high carbon residue rate, economical and efficient novolac resin as charcoal-forming material in his master's thesis "Research on Novolac Resin and Microcapsule ...

Problems solved by technology

However, the flame retardancy of ABS resin is poor. How to find an additive that can improve the flame retardancy of ABS resin without reducing its excellent performance has become a research hotspot.

[0003] Yang Bing used low-toxicity, low-smoke, high temperature resistance, high carbon residue rate, economical and efficient novolac resin as charcoal-forming material in his master's thesis "Research on Novolac Resin and Microcapsule Red Phosphorus Halogen-Free Flame Retardant ABS". As an agent, microencapsulated red phosphorus is used as a synergistic flame retardant, basic magnesium sulfate whiskers are used as inorganic flame retardant, and nitrile rubber with good compatibility with ABS matrix is ​​selected for toughening modification. After plasticizing on a double-roll mill at 180°C, add antioxidants and evenly mixed novolak resin, microcapsule red phosphorus, inorganic flame retardant basic magnesium sulfate whiskers, and nitrile rubber blends in sequence, and knead After uniformity, the material is discharged and placed in the mold, hot-pressed on a flat vulcanizing machine at 180°C for 10 minutes, and then cold-pressed at room temperature for 10 minutes, and the modified ABS plastic sheet is molded, but the flame retardant effect is insufficient.
