Problems solved by technology

Base-material soluble and base-material insoluble antifouling coatings with cuprous oxide as antifouling agent have a common disadvantage: the antifouling period is not long, and these antifouling coatings also have many problems in terms of film strength. Moreover, although the antifouling coating containing cuprous oxide can effectively prevent large-scale biofouling, it is difficult to remove a small amount of microbial fouling.
Cuprous oxide is an antifouling agent with a long history of application. It has the advantages of low toxicity and low price, but also has the disadvantages of easy sedimentation and unstable release rate.

Abstract

The invention discloses a method for preparing a novel nanometer cuprous oxide antifouling material by using a mechnochemical process. Process steps and technological parameters for preparation of the material are as follows: a steel ball mill pot is used, zirconia beads with a radius of 0.4 to 0.6 mm are added into the pot, 40 to 50 parts of cuprous oxide, 10 to 25 parts of thermoplastic acrylic resin, 1 to 3 parts of a dispersant, 0.1 to 0.3 part of an antifoaming agent, 0.2 to 1 part of a coupling agent and 25 to 40 parts of butyl acetate are added into the pot, and all the above-mentioned components account for 65 to 80% of the volume of the ball mill pot; planetary rotary ball milling is carried out at a rotation speed of 300 to 600 r / min, temperature is controlled to be in a range of 40 to 60 DEG C, and time for ball milling is 4 to 8 h; then the ball mill pot is shut down, and filtration is carried out so as to obtain orange ball milling liquid of nanometer cuprous oxide, wherein the cuprous oxide in the orange ball milling liquid is common micron red cuprous oxide powder. The method provided in the invention has the advantages of no need for water, friendliness to environment and no discharge of toxic and harmful substances.

Description

technical field [0001] The invention relates to nanometer materials, in particular to preparing nano cuprous oxide antifouling new materials by mechanochemical ball milling, and adopting specific dispersion and stabilization technology to obtain the new nano cuprous oxide antifouling materials with stable performance. Background technique [0002] The vast ocean has brought abundant natural resources to human beings. However, in the process of human development of marine resources, a major problem of biofouling has been encountered. The growth of marine organisms on the hull will increase the weight of the ship and the roughness of the bottom surface of the ship. Generate resistance when the ship is sailing, consume more fuel, damage the power machinery, shorten the time interval between docking repairs and shorten the service life of the ship, resulting in huge economic losses. [0003] So far, the effective and commonly used method to prevent marine biofouling is to apply ...
