Description

Technical Field

[0001] The utility model relates to the technical field of halogen-free flame-retardant EVA masterbatch, in particular to an environmentally friendly halogen-free flame-retardant EVA masterbatch synthesis device. Background Art

[0002] At present, halogen-free flame-retardant EVA masterbatch is a special colorant for polymer materials that combines the properties of EVA (ethylene-vinyl acetate copolymer) and flame retardant. It is mainly composed of pigments or dyes, EVA carriers, and additives such as flame retardants, plasticizers and antioxidants. This masterbatch is formed by uniformly loading pigments or dyes into EVA resin to form an aggregate with excellent coloring ability and flame retardant properties.

[0003] Halogen-free flame retardant EVA masterbatch synthesizer is a kind of equipment specially used for producing halogen-free flame retardant EVA masterbatch. The equipment adopts advanced synthesis technology and process, and realizes efficient synthesis of halogen-free flame retardant EVA masterbatch by precisely controlling the mixing, melting, reaction and cooling of raw materials.

[0004] The equipment usually includes raw material pretreatment system, melting reaction system, cooling and curing system and masterbatch collection system. The raw material pretreatment system is responsible for uniformly mixing and pretreatment of raw materials such as EVA resin, pigment, flame retardant, etc., in preparation for the subsequent melting reaction. The melting reaction system melts and reacts the pretreated raw materials at high temperature to form a uniform molten material. The cooling and curing system converts the molten material into solid masterbatch by rapid cooling and curing. Finally, the masterbatch collection system is responsible for collecting, packaging and storing the cooled and cured masterbatch.
