Problems solved by technology

However, the existing hydroponic water tank materials are usually obtained by directly adding antibacterial and anti-algae additives to the base material. Because the antibacterial and anti-algae additives are basically derived from inorganic antibacterial agents, and the most widely used inorganic antibacterial agents are nano-silver antibacterial agents. , although it shows a strong antibacterial effect, it is very easy to agglomerate when it is directly compounded with the polymer matrix resin, which greatly affects its antibacterial performance. Discoloration of the polymer matrix in which it is placed

Abstract

The invention provides a yellowing-resistant antibacterial polyolefin material and a water tank for water culture. The polyolefin material comprises the following components in parts by weight: 100 parts of polyolefin resin, 0.1-1 part of an antibacterial functional agent and 0.1-1 part of an antioxidant, wherein the antibacterial functional agent is a modified graphene silver-loaded composite antibacterial agent. The yellowing-resistant antibacterial polyolefin material provided by the invention has the advantages of good dispersity, excellent comprehensive antibacterial performance and no yellowing of a high polymer product.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a yellowing-resistant and antibacterial polyolefin material and a water tank for hydroponics. Background technique [0002] With the improvement of people's material and cultural living standards, hydroponic farming is becoming more and more popular, and the development of science and technology has also made soilless cultivation technology widely used. However, fungi or algae in water have long puzzled practitioners in the field of hydroponic culture. For example, as time goes by, bacteria, algae and other microorganisms are usually produced on the surface of the hydroponic tank, which not only produces bad smell, damages the appearance, but also causes the death of animals and the withering of plants. [0003] At present, in order to solve the above problems, the hydroponic water tank with anti-bacteria or anti-algae function is developed to prevent the growth and reproducti...
