Embodiment 1

[0027] Example 1: Preparation of polypropylene composite material for water purifier filter bottle shell

[0028] Weigh the corresponding raw materials according to the above weight parts: see Table 1

[0029] After that, the homopolypropylene, copolymer polypropylene, Vistamaxx elastomers, fillers, antioxidants, lubricants, antibacterial agents, nucleating agents, and titanium dioxide weighed in proportion are mixed uniformly from the main feed The port is added to the parallel twin-screw extruder, so that all the component materials are sheared, melt-blended and extruded in the parallel twin-screw extruder. The processing temperature of the twin-screw extruder is 180°C in the first zone and 190°C in the second zone. , Three-zone 200℃, four-zone 220℃, five-zone 220℃, six-zone 215℃, seven-zone 215℃, eight-zone 215℃, nine-zone 210℃, ten-zone 210℃, machine head 220℃;

[0030] Finally, the material strips exiting the die of the parallel twin-screw extruder are cooled, dried, and pellet...

Abstract

The invention discloses a polypropylene composite material for the shell of the filter bottle of a water purifier. The polypropylene composite material is characterized by comprising homo-polypropylene, co-polypropylene, a Vistamaxx elastomer, a filler, an antioxidant, a lubricant, an antibacterial agent, a nucleating agent, and titanium dioxide according to a ratio of (59.2-69.2):(14-20):(1-3):12:0.4:0.3:1:0.1:2; wherein the isotacticity of homo-polypropylene is not less than 96%, the melting index is not more than 6g/10min; the melting point of co-polypropylene is not higher than 140 DEG C;and the melt flowing speed of the Vistamaxx elastomer is greater than 500g/10min. After spinning melting processing, the strength of the fusion face of the composite material is high, and thus the composite material can bear a high circulation water pressure, will not be broken, and can be used to prepare a water purifier filter bottle shell.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polypropylene composite material for a water purifier filter bottle housing. Background technique [0002] Polypropylene is one of the five general-purpose plastics with the largest output. It has excellent mechanical and chemical properties, is low in price, and has a wide range of sources. It has been widely used in automobiles, home appliances, packaging, construction and other fields, and has become the most developed general-purpose resin. Quick variety. Many existing manufacturers use modified polypropylene composite materials to produce water purifier filter bottle shell products. During the manufacturing process of this product, the two semi-finished parts need to be welded into a whole by a spinning process. The quality of the weld will be affected. It affects the overall ability of the filter bottle product to resist external tap water pressure, so it is particu...
