Description
Technical Field
The invention relates to a vertical fiber marine antifouling material and a preparation method thereof, in particular to a vertical fiber marine antifouling material modified by a zwitterionic polymer and a preparation method thereof, and belongs to the field of materials.
Background
The attachment and growth of marine organisms on underwater structures and ship bottoms can cause economic losses such as increased navigation resistance, increased fuel consumption, accelerated corrosion and the like, the traditional antifouling paint realizes an antifouling target by releasing an antifouling agent to drive or poison fouling organisms, but the released antifouling agent can generate negative effects on ecological systems and marine environments. In view of this, the antifouling Paint company of International Paint has proposed a biocide-free antifouling Paint based on the non-stick property of silicone-based surfaces, but the antifouling effect is not ideal.
The preparation of the antifouling material without antifouling agent release can be realized by designing a vertical fiber surface structure in the United states patent US 5618588, and the soft fiber vertical to the surface of the material can swing and bend to form a dynamic surface so that marine fouling organisms are not easy to attach or not firmly attached, thereby achieving the purpose of inhibiting fouling. However, the material of the ordinary fiber does not have the property of low surface energy or strong hydration, so the surface of the ordinary fiber still can be attached by fouling organisms. A small amount of fouling organisms attached to the surface of the fiber can prevent the fiber from swinging and bending, the fiber which originally has an antifouling effect can intercept fouling organism larvae and fouling organisms floating in the seawater from the seawater at the moment, and in addition, the surface area of the material surface with the fiber is far larger than that of a common material, so that a vicious circle is formed, and subsequent fouling organisms are attached more quickly and more than the common material. The fibers must be modified in order for the vertical fiber stain resist material to be of practical use.
Chinese patent CN 106400498A discloses a method for preparing fibers with good antifouling and fouling release properties by using polyamide fibers as raw materials and modifying the surface of the fibers with a copolymer of a hydrophilic segment with excellent hydration ability and a hydrophobic segment with low surface energy by a surface-initiated atom transfer radical polymerization method. The liquid phase environment and the chemical reaction on the surface are accompanied in the fiber modification process, so that the originally dispersed fibers are agglomerated together, particularly, the modification method of introducing hydrophilic groups with good antifouling performance on the fiber surface can further lead the fibers to absorb moisture in the air and agglomerate, and the factors can not form the special appearance of the fibers vertical to the surface, even can not flock. Patent CN 109294431A discloses that vinyltrimethoxysilane, polylactic acid and a silane coupling agent KH-560 are adopted to modify a nylon raw material, then nylon tows are prepared by electrostatic spinning and cut into fluff, and the fluff is added into a coating. The surface chemical composition introduced by the modification method of the invention has neither enough low surface energy nor excellent hydration capability, so that the improvement of the antifouling performance by modification is limited, and meanwhile, the modification means has complex process flow and is greatly limited by raw materials, and only modified nylon fluff can be produced. The fiber surface can not be effectively modified on the premise of maintaining the special surface morphology of the vertical fiber marine antifouling material regardless of the mode of carrying out polymerization grafting modification on the fiber surface or modifying the fiber and then spinning and cutting the fiber.

Technical description:
during the preparation process of the vertical fibers, the adhesive coating on the bottom layer is too thin, so that the fibers are not firmly bonded, and the fluff is wrapped by the adhesive due to too thick coating. Typically diatoms and other micro-fouling organisms are about 10 to 20 microns in size, with too large a diameter of the fibres increasing the surface to which the fouling organisms can attach, too short or too loose fibres being unable to effectively block the fouling organisms from contacting the substrate, and too long or too dense fibres trapping the fouling organisms.
According to the method in the surface modification process of the fiber, trace elemental iron is deposited on the surface of the fiber through a reduction reaction, and then a free radical polymerization reaction is initiated by utilizing a trace ferrous iron catalytic initiator released by the elemental iron in a methacryloyl ethyl sulfobetaine monomer solution, so that the surface of the fiber is wrapped by the polymethacrylyl ethyl sulfobetaine. The concentration of the used ferrous chloride solution is lower than 0.03mol/L or the concentration of the used sodium borohydride solution is lower than 0.06mol/L, so that the iron content on the surface of the fiber is too low, the free radical polymerization reaction can not be effectively initiated, and the polymethacryloxyethyl sulfobetaine can not completely wrap the surface of the fiber; the concentration of ferrous chloride solution is higher than that of sodium borohydride solution or higher than 0.15mol/L, excessive iron is deposited, excessive polymethacryloxyethyl sulfobetaine is generated, and fiber adhesion is caused. Meanwhile, the monomer fraction in the aqueous solution is less than 5 parts or the initiator dosage is less than 0.05 part, which leads to insufficient polymethacryloxyethyl sulfobetaine, while the monomer fraction is more than 7 parts or the initiator dosage is more than 0.07 part, which leads to excessive polymethacryloxyethyl sulfobetaine, which leads to fiber adhesion. The amount of the crosslinking agent less than 0.05 part may result in the decrease of the stability of the polymethacryloxyethylsulfonobetaine layer in seawater, and the amount of the crosslinking agent more than 0.07 part may result in the deterioration of the hydration ability of the polymethacryloxyethylsulfonobetaine.
Compared with the prior art, the invention has the beneficial effects that:
(1) According to the invention, amphoteric ionization modification of the vertical fiber marine antifouling material is realized, and the polymethacryloxyethyl sulfobetaine is coated on the surface of each fiber, so that the material on the surface of the fiber has very strong antifouling capability, and the inherent defect of the application of the common vertical fiber material in the marine antifouling field is overcome.
(2) The invention realizes the zwitterionization modification, and simultaneously keeps the original appearance that the vertical fiber material fibers are uniformly dispersed and are not adhered, which is beneficial to the exertion of the antifouling function.
(3) The invention can simultaneously inhibit the attachment and growth of multi-scale fouling organisms and can meet the actual antifouling value.
(4) According to the invention, no antifouling agent is added, and the finally obtained zwitterion modified vertical fiber marine antifouling material has no pollution to the environment.

Polydimethylsiloxane is the most widely used of nontoxic antifouling materials, and the antifouling effect of vertical fibers is obviously superior to that of the vertical fibers. Considering that the nylon plate and the fiber are made of the same material, the small fiber diameter is the key to prevent the adhesion of diatom.
From Table 2, it can be seen that the zwitterionic modified vertical fiber marine antifouling material can greatly reduce adhesion of mussel byssus, and particularly, the fiber density is 80g/m 2 The above zwitterionThe modified vertical fiber marine antifouling material completely inhibits mussels from secreting byssus on the surface of the mussels in the test.
