preparation example Construction

[0039] The preparation method of the high-gloss halogen-free flame-retardant antibacterial PP material of the present invention comprises the following two steps:

[0040] (1) One-step granulation: such as figure 1 As shown, add PP and compatibilizer into the high-speed mixer in proportion, add diffusion oil for preliminary mixing, and then add mineral fillers, antioxidants, lubricants, nucleating agents and part of flame retardants in proportion to The high-speed mixer is used for mixing, and after mixing evenly, it is transported to the twin-screw extruder for mixing. The part of the flame retardant refers to 30%-40% of the total mass of the flame retardant. The aspect ratio of the twin-screw extruder is 40:1, and the temperature of each temperature zone of the extruder is one stage: 180-195°C; two stage: 195-205°C; three stage: 195-205°C; four stage: 205-215°C; 5th stage: 205-220°C; 6th stage: 210-220°C; 7th stage: 205-210°C; head 190-205°C. The extruded material is cool...

Abstract

The invention provides a high-luster halogen-free flame-retardation antibiosis PP material and a manufacture method thereof. The high-luster halogen-free flame-retardation antibiosis PP material comprises the following components by weight part: 65-80 parts of polypropylene, 2-15 parts of mineral matter filling material, 10-30 parts of P-N halogen-free fire retardant, 3-10 parts of compatilizer, 0.1-1 part of nucleating agent, 0.2-1 part of degradation agent, 0.2-2 parts of lubricant, 0.1-0.4 parts of anti-oxidant, 0.1-0.3 parts of anti-dripping agent, 0.1-0.3 parts of antiseptic and 0.2 parts of light stabilizing agent. According to the invention, a high efficiency N-P nano composite flame retardation system is employed for halogen-free flame-retardation filling modification on a polypropylene material, is suitable for household electrical appliance case and bathroom equipment, and can reach the purposes of highlight halogen-free environmental protection flame retardation and antibiosis.

Description

technical field [0001] The invention belongs to the field of flame-retardant materials, and in particular relates to a high-gloss halogen-free flame-retardant and antibacterial PP material suitable for home appliance shells and sanitary equipment and a manufacturing method thereof. Background technique [0002] At present, plastic products are more and more widely used, and the requirements for appearance are getting higher and higher. Traditional high-gloss products are mostly produced by ABS, HIPS, ABS / PMMA alloy and other products. Polypropylene (PP), as a general-purpose plastic with good rigidity, light specific gravity, and high elasticity, has good heat resistance, chemical stability, and insulation, and is widely used in many fields of production and life. The field has occupied a certain seat. High-gloss PP can replace ABS, HIPS and other high-gloss products. At home and abroad, high-gloss PP has been widely used in microwave ovens, water heaters, rice cookers and...
