Residual oil modified fire retardation agent composition and fire retardation polyolefin material prepared from the same

Abstract

The present invention discloses a phosphate ester fire retardation agent prepared through a residual oil modification reaction, and a method for preparing a fire retardation polyolefin composite material by adopting an intumescent fire retardation agent prepared through compounding of the phosphate ester fire retardation agent. According to the method, aromatic distillate is separated from residual oil, an organic phosphorus compound grafting reaction is performed to prepare a residual oil modified fire retardation agent, 10-30 parts by mass of the residual oil modified fire retardation agent, 30-50 parts by mass of ammonium polyphosphate, and 10-30 parts by mass of ammonium polyphosphate melamine are mixed, and the obtained mixture, 1-5 parts by mass of a synergist and 1-5 parts by mass of an antioxidant are subjected to a blending and melting composite process to prepare the intumescent fire retardation agent. According to the present invention, the residual oil modified fire retardation agent component is adopted as the charcoal source and the acid source, and the residual oil modified fire retardation agent component, the ammonium polyphosphate (acid source, gas source), and the ammonium polyphosphate melamine (air source) form the intumescent fire retardation agent so as to provide characteristics of no corrosive gas, low smoke, low toxicity, and good fire retardation; 10-35 parts by mass of the fire retardation agent composition is added to 90-65 parts by mass of the polyolefin, such that the fire retardation is significantly improved, and the mechanical property is not affected; and with the residual oil modification approach, the high added value utilization of the residual oil is achieved, and the new rich source is provided for the fire retardation agent.

Description

technical field [0001] The invention relates to a residue oil modified flame retardant composition and a preparation method thereof, in particular to a residue oil modified flame retardant composition used for flame retardancy of polymer materials and a preparation method thereof. Background technique [0002] Due to the development of oil and gas resource exploitation to deep and ultra-deep layers, the proportion of heavy crude oil in global resources has gradually increased, resulting in a huge accumulation of residual oil. There are about 50Mt of residual oil that is difficult to convert in my country every year, and the efficient utilization of residual oil has become an urgent problem to be solved. The conversion of residual oil into light components can increase the yield of refined oil and is one of the ways to efficiently utilize residual oil. However, the residual oil lightening technology has high energy consumption, poor environmental protection and low comprehen...

AI Technical Summary

Problems solved by technology

[0022] In the prior art, reasonable use of residual oil to synthesize flame retardants can obtain relatively good flame retardant effects, but because they belong to inorganic flame retardants, their compatibility with organic polymer materials is not good, and the dispersibility needs to be improved. , the amount of addition has a great influence on the mechanical properties of the material, so there are application limitations

[0023] Although the prior art has reported many of the above-mentioned phosphate ester flame retardants and their preparation methods for preparing high polymer flame retardant materials, the aromatics separated from the residual oil are modified by organic reactions, thereby synthesizing the residual oil modified It is the first time at home and abroad that the method of using non-toxic flame retardants and using them in flame retardant polyolefin materials is proposed, and it can be considered as an original and innovative technology.
