Embodiment 1

[0018] A plastic that effectively inhibits the growth of bacteria comprises the following raw materials in parts by weight:

[0019] 90 parts of polypropylene, 4 parts of metallocene polyethylene, 3 parts of epoxy soybean oil, 4 parts of stearyl alcohol, 2 parts of vinyltriethoxysilane, 2 parts of nano zirconium phosphate, 3 parts of corn straw fiber, 3 parts of seaweed fiber 1 part, 2 parts of bitter almond oil, 3 parts of nano palygorskite, 10 parts of antibacterial agent, 1 part of antimony trioxide, 1 part of potassium sorbate.

[0020] The antibacterial agent is composed of chitosan, silver-loaded zeolite and nanometer copper powder with a mass ratio of 1:3:4.

[0021] The preparation method of the above-mentioned plastics that can effectively inhibit the growth of bacteria is to weigh each raw material according to the proportion, mix, melt and knead, and extrude and granulate.

Embodiment 2

[0025] The antibacterial agent is composed of chitosan, silver-loaded zeolite and nanometer copper powder with a mass ratio of 1:4:3.

[0026] The preparation method of the above-mentioned plastics that can effectively inhibit the growth of bacteria is to weigh each raw material according to the proportion, mix, melt and knead, and extrude and granulate.

Embodiment 3

[0028] A plastic that effectively inhibits the growth of bacteria comprises the following raw materials in parts by weight:

[0029] 110 parts of polypropylene, 6 parts of metallocene polyethylene, 5 parts of epoxy soybean oil, 7 parts of stearyl alcohol, 4 parts of vinyltriethoxysilane, 4 parts of nano zirconium phosphate, 6 parts of corn straw fiber, 6 parts of seaweed fiber 5 parts of bitter almond oil, 6 parts of nano palygorskite, 16 parts of antibacterial agent, 3 parts of antimony trioxide, and 3 parts of potassium sorbate.

[0030] The antibacterial agent is composed of chitosan, silver-loaded zeolite and nanometer copper powder with a mass ratio of 1:5:2.

[0031] The preparation method of the above-mentioned plastics that can effectively inhibit the growth of bacteria is to weigh each raw material according to the proportion, mix, melt and knead, and extrude and granulate.

Abstract

The invention relates to plastic for effectively inhibiting the breeding of bacteria. The plastic is prepared from the following raw materials in parts by weight: 90 to 110 parts of polypropylene, 4 to 6 parts of metallocene polyethylene, 3 to 5 parts of epoxidized soybean oil, 5 to 7 parts of octadecanol, 2 to 4 parts of triethoxyvinylsilane, 2 to 4 parts of nano zirconium phosphate, 3 to 6 partsof corn straw fiber, 3 to 6 parts of seaweed fiber, 2 to 5 parts of bitter almond oil, 3 to 6 parts of nano palygorskite, 10 to 16 parts of an antibacterial agent, 1 to 3 parts of a flame retardant and 1 to 3 parts of a preservative. The plastic provided by the invention has good comprehensive performance; antimony trioxide is used as the flame retardant so that the disadvantage that the plasticis combustible in an application process is prevented and the safety of the plastic is improved. The antibacterial agent composed of chitosan, silver-loaded zeolite and nano copper powder is added torealize the effect of inhibiting or killing the bacteria, so that the breeding of the bacteria is avoided and the quality of the plastic is further improved.

Description

technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to a plastic which can effectively inhibit bacterial growth and a preparation method thereof. Background technique [0002] Toys play an important role in children's lives, and toys are children's friends. Plastics used to make toys must be safe, healthy and non-toxic. But in daily life, quite a few harmful bacteria exist and multiply on the surface of plastic products, and cause various diseases through contact. As people's awareness of health and environmental protection continues to increase, there is a demand for "bacteriostasis and sterilization" for toy plastic parts that are frequently in contact with in daily life. Contents of the invention [0003] The object of the present invention is to provide a plastic that effectively inhibits the growth of bacteria and a preparation method thereof. [0004] In order to achieve the above object, the present invention ...
