Novel wormwood PP plastic applied to toilet lid

Abstract

The invention provides a novel wormwood PP plastic applied to a toilet lid. The novel wormwood PP plastic is prepared by blending wormwood PP master batch and common PP slices, wherein the addition amount of the wormwood PP master batch is 1-10% of the total mass of the PP plastic; the wormwood PP masterbatch is prepared from the following raw materials in parts by weight: 90-100 parts of PP, 8-10parts of wormwood functional particles, 15-20 parts of glass fibers, 3-5 parts of triphosphite, 2-3 parts of modified bentonite, 1-2 parts of calcium stearate, 1-2 parts of diphenyl carbonate, 2-3 parts of tetrabutylammonium hydrogen sulfate, 0.5-1 part of an antioxidant and 1-5 parts of a coupling agent. The antibacterial rate of the novel wormwood PP plastic applied to the toilet lid to bacteria such as staphylococcus aureus, escherichia coli and candida albicans is 98.1-99.4%; the mildew-proof grade is 0 grade; the tensile strength is 35-37 MPa, and the shrinkage rate is 0.42-0.66%.

Description

technical field [0001] The invention relates to the field of PP plastics, in particular to a novel wormwood PP plastic used in toilet lids. Background technique [0002] With the increasing awareness of product safety and hygiene, the global antimicrobial plastics market continues to expand in size. Relevant research reports predict that by 2015, the global industrial application market of antibacterial plastics will reach 1.4 billion pounds, and the value of products used in consumer goods will be 1.03 billion pounds. 20% of the world's plastic products have antibacterial functions. [0003] At present, Japan and other developed countries have a high penetration rate of antibacterial home appliances. They launched antibacterial refrigerators, antibacterial washing machines and other household appliances as early as the early 1990s. Currently, antibacterial home appliances account for more than 50% of the home appliance market. Japan's antibacterial plastics cover all types...

Problems solved by technology

[0013] (1) To overcome the problem of rapid loss of antibacterial components on the surface of PP plastic antibacterial toilet lids and the inability to maintain good antibacterial performance for a long time;

[0014] (2) To overcome the problem of poor processing stability of antibacterial ingredients, which is easily affected by the process conditions in the processing process and cause loss or failure;

[0015] (3) To overcome the unsatisfactory distribution of added antibacterial ingredients in PP plastics, and the problem that PP plastics should have physical properties decline
