Abstract

The invention discloses a novel halogen-free flame-retardant master batch which is composed of the following components: polyphenylene oxide (PPO / PPE) resin, high impact polystyrene (HIPS) resin, hydrogenated styrene copolymer (HSBC), an organophosphate liquid flame retardant, a hindered phenol antioxidant, a thioacid or thioether antioxidant, a phosphite ester antioxidant, a compatilizer, an ultraviolet absorbent, a quencher and an anti-dripping agent. The invention also provides a preparation method of the novel halogen-free flame-retardant master batch. The preparation method comprises thefollowing steps: adding the resin and other assistants into a mixer, and uniformly mixing the resin and the other assistants; adding a preheated liquid flame retardant, and fully and uniformly mixing;finally, discharging the mixed materials and putting the mixed materials into a double-screw extruder, and conducting melt extrusion, cooling and granulation after technological parameters are set. The problem that a liquid flame retardant is complex in use link and serious in environmental pollution in the prior art is solved. The novel halogen-free flame-retardant master batch is low in production cost and environment-friendly, and can support continuous production of flame-retardant products.

Description

technical field [0001] The invention belongs to the field of thermoplastic general-purpose plastics and thermoplastic engineering plastics, and in particular relates to a preparation method of a novel halogen-free flame-retardant masterbatch. Background technique [0002] With the development of the polymer material industry, polymer materials are widely used in many fields such as walls, ceilings, furniture, floor coatings, fabrics, electronics, vehicles and electrical appliances. Since most polymers are organically flammable, fire safety is extremely important in every application. Generally, the flame retardancy of polymers is improved by adding flame retardants to polymers. Flame retardants consist of compounds that are added to materials to increase their fire and heat resistance or ability to resist flames. [0003] Traditionally, most of the flame retardants used in common polymers are inorganic solid powders, particles and halogen flame retardants. Inorganic solid p...
