Embodiment Construction

[0014] Ureidophosphate GUP (10~70%) consists of the following raw materials in mass percentage:

[0015] Phosphorus oxygen acid 10~60%

[0016] Dicyandiamide 10~60%

[0017] Water 30~80%

[0018] Synthesis of ureidophosphate GUP: Install a thermometer, stirring device, reflux condenser and dropping funnel on a 250ml four-necked round bottom flask, add 42 grams of dicyandiamide and 60ml of water, heat to 60°C to make dicyandiamine Dissolve; Add 0.25 mol of phosphorous acid and hypophosphorous acid with a concentration of 85% dropwise from the dropping funnel under stirring, and react at a temperature of 95°C until the complete transformation of dicyandiamide takes 25 minutes, and the judgment of the reaction end point can be According to the change of pH value or using infrared spectroscopy, after the reaction is completed, cooling, filtering, crystallization, drying, and crushing, 140 grams of ureidophosphate GUP is obtained. Afte...

Abstract

The invention discloses an environment-friendly halogen-free flame retardant liquid and a preparation method of the halogen-free flame retardant liquid. The method comprises the following steps of: the environment-friendly halogen-free flame retardant liquid is prepared by using 25 parts of ureido phosphate GUP, 2-4 parts of microencapsulated red phosphorus, 18 parts of phosphoric acid, 8 parts of phosphorylated castor oil, 35 parts of deionized water, 6 parts of multidirectional complexing center atom zinc and 3 parts of surfactants as main raw materials; and mixing the materials by controlling proper reaction temperature, thus preparing the environment-friendly halogen-free flame retardant liquid. The environment-friendly halogen-free flame retardant liquid measured by a method of gradually increasing microencapsulated red phosphorus has the effects of high efficiency, low smoke and low toxicity; and the environment-friendly halogen-free flame retardant liquid has good effect when 6 parts of the microencapsulated red phosphorus are reached.

Description

technical field [0001] The invention relates to an environment-friendly halogen-free flame retardant liquid and a preparation method thereof. Background technique [0002] At present, known traditional flame retardant materials widely use flame retardant mixtures composed of halogen-containing polymers or halogen-containing flame retardant liquids. Commonly used halogen flame retardant fluids mainly include chlorine-containing declone, chlorinated paraffin, CPE, and bromine-containing decabromodiphenyl ether, decabromodiphenylethane, tetrabromobisphenol A, HBCD, octabromoether, Brominated polystyrene, brominated epoxy, etc. The bromine series flame retardant liquid represented by decabromodiphenylethane has high flame retardant efficiency in thermoplastic resins, the obtained materials have good mechanical properties, the production process requirements are not complicated, easy to process, and the compatibility with resins such as plastics is relatively good Good, and it ...
