Abstract

The invention relates to a method for preparing a silicon, nitrogen and halogen multielement synergistic fire retardant compound. The structure of the compound is shown in a formula which can be seen in the specification; in the formula, when m is 1, n is 0; when m is 0, n is 1; X is Cl or Br; Y is Cl or Br; OC3H5Y2 is OCH(CH2Br)2, OCH2CHBrCH2Br, OCH(CH2Cl)2 or OCH2CHClCH2Cl. The preparation method comprises the following steps: in an organic solvent, reacting triglycidyl isocyanurate with dimethyl dihalogenosilane for 5-8h at the temperature of 70-100 DEG C, dropwise adding dihalogen propyl alcohol, reacting for 5-8h at the temperature of 70-110 DEG C, and purifying to obtain t isocyanuric acid tri(dimethyl dihalogen propoxy silicane acyloxy propyl halide)ester. The fire retardant provided by the invention is high in fire retarding efficiency, good in char forming effect and is suitable for being used as a fire retardant plasticizer for polyvinyl chloride, polyurethane, epoxy resin and unsaturated resin; in addition, the production process is simple, the cost is low and the industrial production can be easily realized.

Description

technical field

[0001] The invention relates to a preparation method of a silicon, nitrogen and halogen multi-element synergistic flame retardant compound, in particular to a preparation method of tris(dimethyldihalopropoxysilyloxyhalopropyl) isocyanurate. The compound is suitable as a flame retardant plasticizer for polyvinyl chloride, polyurethane, epoxy resin, unsaturated resin, etc. Background technique

[0002] With the promotion of the European Union's implementation of flame retardant and non-halogenated regulations on electronic products, my country introduced the corresponding flame retardant regulations on July 1, 2007, which greatly promoted the research and development of new varieties of flame retardants in my country. The main way of preliminary halogen-free flame retardant is to add magnesium hydroxide, aluminum hydroxide, zinc borate and expanded graphite to the base material, but because of its low flame retardant efficiency, a large amount of filling is req...
