Hydrophobic and oleophobic mildew-proof plastic garbage can and preparation method thereof

Abstract

The invention discloses a hydrophobic and oleophobic mildew-proof plastic garbage can and a preparation method thereof. The product comprises the following components in parts by weight: 20-90 parts of regenerated plastic, 0-70 parts of raw plastic, 0.5-15 parts of a hydrophobic and oleophobic auxiliary agent, 0.5-5 parts of a mildew-proof auxiliary agent, 0-1 part of an antioxidant, 0-2 parts of an ultraviolet light absorber, 0-10 parts of other auxiliary agents, 0-20 parts of filler and 0.5-5 parts of color master batch. According to the invention, the low-melting-point hydrophobic and oleophobic auxiliary agent and the mildew-proof auxiliary agent are mainly gathered on the surfaces of the prepared hydrophobic and oleophobic mildew-proof particles by utilizing the great difference between the low-melting-point hydrophobic and oleophobic auxiliary agent and the high-molecular melt in viscosity in the processing process; furthermore, the auxiliaries are further gathered on the surface of the garbage can prepared from the hydrophobic, oleophobic and mildew-proof particles, so that the prepared garbage can has excellent hydrophobic, oleophobic and mildew-proof characteristics by adopting the low-content hydrophobic, oleophobic auxiliaries and mildew-proof auxiliaries.

Description

technical field [0001] The invention relates to the technical field of trash cans, in particular to a hydrophobic, oleophobic, mildew-resistant plastic trash can and a preparation method thereof. Background technique [0002] At present, garbage classification is steadily advancing in China. Wet garbage generated in daily life is directly put into wet garbage cans. However, the wet garbage cans currently used are not specially designed. The inner wall of the trash can is contaminated with a lot of oil and perishable residues. When the wet trash can is reused, it needs to consume a lot of water to clean it, which increases labor costs. If it is not cleaned, a large number of bacteria and molds will breed, which will affect people's health. [0003] The above problems can be improved by adding functional layers or modifying the plastic used in the barrel body. For example, patent CN 111071659 A discloses a lightweight trash can that is hydrophobic, oleophobic, and antibacteria...
