Synthesis And Application Of New Halogen-free Flame Retardant Cotton With Expandable Anti-wrinkle Agent PNX

This innovative point is: (1) Under the condition of microwave synthesis and separation; phenolic-aldehyde; (2) Water soluble but temporary less resistant to water washing flame retardant synthesis and application research.The main research contents as follows: utilization intermediates the synthesis and characterization of 2,6-diformy-4-methoxyl phenol: microwave conditions with trifluoroacetic acid as a solvent urotropin oxidation of methoxyphenol derivatives synthesis 2,6-diformy-4-methoxyl phenol, Then on the NMR characterization, And again on this foundation synthesis explored of 2,6-diformyl-4-methyl phenol, 2,4,6-triformyl phenol, and 2,6-diformyl-4-Bromine phenol.Flame retardant PNX synthesis and characterization, Use of improved Mannich reaction, let melamine, diethyl phosphite and 2,6-diformy-4-methoxyl phenol reaction synthesis of a kind of new compounds, and carries on the flame retardancy finishing cotton research. Research of flame retardant PNX about retardant fire mechanism:(1) with TG-DTG technology research and flame retardant cotton thermal decomposition temperature, maximum thermal starting weight loss rate peak temperature, maximum thermal weightlessness rate and 800℃under the residues of parameters, such as comparison, as flame retardant mechanism provides the basic data; The theoretical calculation of the preliminary research and puts forward in the flame retardant cotton PNX flame retardancy finishing mechanism. (2) Will flame retardant cotton to test performance of extreme oxygen index, chroma, breaking strength, water processing times and anti-angiogenesis. Through the above characterization techniques and methods of new expandable nitrogen phosphorus flame retardants PNX systematic research, the paper probes flame retardant cotton thermal degradation mechanism and flame retardant mechanism, the results for the future raise cotton flame retardant techniques and develop a resource-conserving, environment-friendly, flame retardant effect excellent flame retardant materials laid solid foundation.This article USES the research methods are: literature investigation, observation, qualitative method, the quantitative method, the quantity methodology, exploratory research, comparative research and experimental research.
