Abstract

The invention discloses an antibacterial, low-odor and flame-retardant polypropylene composite material and a preparation method for the same. The polypropylene composite material is prepared from the following components in parts by weight: 60 to 85 parts of polypropylene, 5 to 15 parts of barium sulfate, 5 to 10 parts of an efficient antimony-free and precipitate-free flame retardant, 5 to 15 parts of a deodorization masterbatch, 0.5 to 1.5 parts of an antibacterial agent, 0.3 to 0.6 part of an antioxidant, 0.1 to 0.5 part of a nucleating agent and 0.5 to 1.0 part of a lubricant. The prepared antibacterial, low-odor and flame-retardant polypropylene composite material has efficient antibacterial performance, and the antibacterial rate is over 99 percent. In addition, the odor level of the prepared antibacterial, low-odor and flame-retardant polypropylene composite material is lower than the 3.5 level, and the flame retardancy reaches the UL94 V-2 level.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an antibacterial, low-odor, flame-retardant polypropylene compound and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin obtained by polymerizing propylene. It is usually a translucent, colorless solid, odorless and non-toxic. Due to its regular structure and high degree of crystallization, its melting point is as high as 167°C, which has the advantages of heat resistance and corrosion resistance; in addition, polypropylene has a low density and is the lightest general-purpose plastic, but PP has poor low-temperature impact and large molding shrinkage. [0003] Antibacterial plastic is a kind of plastic that can inhibit or kill bacteria, mold, yeast, algae and even viruses that contaminate itself in the use environment. It is a well-known new type of material that is suitable for health and hygiene. With the increasing awareness ...
