Embodiment 1

[0026] N-(3,4-dihydroxyphenyl) ethyl-methacrylamide copolymer, the structural formula of the copolymer is:

[0027]

[0028] N-(3,4-dihydroxyphenyl) ethyl-methacrylamide copolymer is prepared by the following method: ① In parts by weight, weigh 3 parts of 3-(trifluoromethyl)styrene , 0.2 parts of N-(3,4-dihydroxyphenyl) ethyl-methacrylamide, 0.03 parts of cuprous chloride, 0.4 parts of 2,2′-bipyridyl, 0.03 parts of benzyl bromide; For the treated toluene, argon gas was passed through it for 15 minutes; the materials prepared in step ① were added to the toluene, and stirred and reacted for 6 hours under the protection of argon at a temperature of 50° C.; the reaction equation is shown in Eq.1. ③ Evaporate the solution after the reaction in step ②, and then wash it with methanol and acetone for 4 times to remove the solvent attached to the surface of the precipitate to obtain the product. Each part by weight is 10 g.

Abstract

The invention discloses a N-(3,4-dihydroxyl phenyl)ethyl-methacrylamide copolymer and a preparation method therefor. By taking dopamine and a fluorine-containing compound as raw materials, the dopamine is modified by using the fluorine-containing compound by virtue of a copolymerization method so as to prepare the copolymer containing a fluorine-containing compound side chain and a pyrocatechol-anchored radical side chain. The copolymer, on the one hand, has a pyrocatechol-anchored radical of dopamine to provide a good adhesive performance; one the other hand, the coplymer has the fluorine-containing compound radical, so that the copolymer has oil resistance, corrosion resistance and a hydrophobic and oleophobic property, and the protective performance of a functional protecting coating is extremely improved. The invention further discloses a functional protecting surface material with a good adhesive performance. The material is obtained by self-assembling the N-(3,4-dihydroxyl phenyl)ethyl-methacrylamide copolymer on the surface of the material by soaking. The material has a good protecting performance, a super-hydrophobic property, an antifouling capability and a adhesive performance; is wide in application range of a base; and is non-toxic and free of pollution.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a functional protective surface material, in particular to a functional protective surface material with good adhesion performance and a preparation method thereof. Background technique [0002] With the rapid development of the marine economy and the acceleration of the use of marine space, marine structural engineering such as breakwaters, piers, sea airports, subsea tunnels and sea-crossing bridges has become more and more widely used. At the same time, due to long-term immersion in seawater, erosion, and the impact of wind waves and tides, the corrosion of marine structural engineering has become increasingly prominent, seriously endangering the safety and durability of marine structural engineering. Therefore, more and more attention has been paid to the corrosion protection of marine structures. At present, the 100-year safe service requirement for marine structural engineering ne...
