Inflaming retarding automobile plastic-absorbing material loaded with TiO2-diatomite and preparation method thereof

Abstract

The invention discloses an inflaming retarding automobile plastic-absorbing material loaded with TiO2-diatomite and a preparation technique thereof. The inflaming retarding automobile plastic-absorbing material is characterized in that acrylonitrile-butadiene-styrol copolymer (ABS), line-type phenolic aldehyde resin, microcapsule red phosphorus, basic magnesium sulfate whisker, butadiene-acrylonitrile rubber, mesoporous molecular sieve SBA-15, ammonium polyphosphate, melamine formaldehyde resin, kaolin, Sb2O3, simethicone, grapheme, butyl titanate, glacial acetic acid, nitric acid, diatomite, cerous nitrate and the like serve as raw materials. According to the inflaming retarding automobile plastic-absorbing material loaded with TiO2-diatomite, bond linking is generated between mediation hole molecular sieves and the line-type phenolic aldehyde resin, and thus heat stability of substrate resin is improved; the synergistic effect is generated between the microencapsulation ammonium polyphosphate and antimony oxide / kaolin composite inflaming retarding micro powder, and thus the inflaming retarding effect is better; the grapheme is added into an ABS resin substrate, so that flame retardance and heat stability of the resin are obviously improved, and the mechanical property is higher; and the inflaming retarding automobile plastic-absorbing material loaded with TiO2-diatomite is obtained.

Description

technical field [0001] The invention relates to the technical field of flame retardancy of composite materials, in particular to a loaded TiO 2 - Diatomaceous earth flame-retardant automobile plastic-absorbing material, and its preparation process. 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 Red Phosphorus...

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.
