Zwitterionic polymer modified vertical fiber marine anti-pollution material and preparation method thereof

Abstract

The invention provides a zwitterionic polymer modified vertical fiber marine anti-pollution material and a preparation method thereof. The preparation method comprises the steps that firstly, a vertical fiber material is soaked in a ferrous chloride solution for 0.5-2 h; secondly, the vertical fiber material in the first step is taken out, the ferrous chloride solution is controlled, and a sodiumborohydride solution is uniformly sprayed onto the vertical fiber material; thirdly, the vertical fiber material treated by the sodium borohydride solution in the second step is soaked into a solutionof methacryloyl ethyl sulfobetaine monomer, a cross-linking agent and a free radical polymerization initiator, and reacting is carried out for 15 minutes to 1 hour in a room temperature environment under nitrogen protection; and fourthly, the vertical fiber material with reacting finished in the third step is washed, and redundant polymethacryloyl ethyl sulfobetaine on the surface is washed off to expose the fibers, and the zwitterionic modified vertical fiber marine anti-pollution material can be obtained. The material is free of an anti-pollution agent and meanwhile has good anti-pollutionperformance, and the inherent defects of a common vertical fiber material applied to the marine anti-pollution field are overcome.

Description

technical field [0001] The invention relates to a vertical fiber marine antifouling material and a preparation method thereof, in particular to a zwitterionic polymer modified vertical fiber marine antifouling material and a preparation method thereof, belonging to the field of materials. Background technique [0002] The attachment and growth of marine organisms on the underwater structure and the bottom of the ship will cause economic losses such as increased navigational resistance, fuel consumption, and accelerated corrosion. Traditional antifouling coatings release antifouling agents to drive or kill fouling organisms to achieve antifouling goals. However, the antifouling agents released by it will have a negative impact on the ecosystem and marine environment. In response to this, antifouling coating companies such as International Paint have introduced biocide-free antifouling coatings based on the non-stick properties of silicone-based surfaces, but their antifouling...

AI Technical Summary

Problems solved by technology

The surface chemical composition introduced by the modification method of this invention has neither sufficiently low surface energy nor excellent hydration ability, so the improvement of antifouling performance by modification is limited, and the modification process is complicated and limited by raw materials Extremely large, only modified nylon fluff can be produced

No matter whether the fiber surface is modified by polymerization and grafting or by modifying the fiber and then spinning and cutting, the effective modification of the fiber surface cannot be achieved under the premise of maintaining the special surface morphology of vertical fiber marine antifouling materials.
