Chemically-nickel-plated and palladium-free-activated flame-retardant automotive blister material and preparation method thereof

Abstract

The invention discloses a chemically-nickel-plated and palladium-free-activated flame-retardant automotive blister material and a preparation method thereof. The material is characterized by being prepared from raw materials such as acrylonitrile-butadiene-styrene (ABS) copolymers, novolac, microencapsulated red phosphorus, basic magnesium sulfate whiskers, acrylonitrile-butadiene rubber, mesoporous molecular sieves SBA-15, ammonium polyphosphate, melamine formaldehyde resin, kaolin, Sb2O3, dimethicone, graphene, sodium hydroxide, a silane coupling agent, sodium borohydride, nickel sulfate and the like. The mesoporous molecular sieves and the novolac of the material have the keying effect, so that the heat stability of matrix resin is improved; the microencapsulated ammonium polyphosphate and antimony oxide / kaolin composite flame-retardant micro-powder have the synergistic effect, and thus the flame-retardant effect is better; the graphene is added to the ABS resin matrix, accordingly, the flame retardance and the heat stability of resin are obviously improved, and the mechanical property is higher; and the chemically-nickel-plated and palladium-free-activated flame-retardant automotive blister material is obtained.

Description

technical field [0001] The invention relates to the technical field of flame retardant of composite materials, in particular to an electroless nickel-plating non-palladium-activated flame-retardant automobile plastic-absorbing material 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 Microc...

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.
