Abstract

The invention relates to a tris(2-chloro-3-[tris (dichloropropoxy) silicon acyloxy] propyl) isocyanurate fire retardant compound and a preparation method of the compound. The compound has a structure shown in the specification. The preparation method comprises the following steps: adding isocyanurate triglycidyl to silicon tetrachloride according to a certain mole ratio and carrying out thermal-insulation reacting for 4-5h at 60 DEG C; then dropwise adding dichloropropanol according to a certain mole ratio and carrying out thermal-insulation reaction for 4-6h at 50-70 DEG C; and finally purifying to obtain the tris(2-chloro-3-[tris(dichloropropoxy) silicon acyloxy] propyl) isocyanurate. The compound is an excellent fire retardant plasticizer and the production process is simple, low in equipment investiment and is suitable for industrial production.

Description

technical field [0001] The invention relates to a triazine chlorotrisilicate compound and a preparation method thereof, in particular to a tri{2-chloro-3-[tri(dichloropropoxy)silyloxy]propyl}isocyanate Urate compound and its preparation method. The compound is a three-element synergistic flame-retardant plasticizer of nitrogen, silicon, and chlorine, and is suitable for use as a flame-retardant plasticizer for polyvinyl chloride, polyurethane, epoxy resin, and unsaturated resin. Background technique [0002] Due to the wide application of flammable polymer materials, the research of flame retardant technology and the rapid development of flame retardant plasticizer industry have been promoted. Flame retardant plasticizer is a plastic processing aid with flame retardant function and plasticizing effect. It can overcome the problem of making polymer materials more flammable due to the addition of plasticizers. At present, there is a strong urgency in the market for new high-...
