Embodiment 1
[0029] Embodiment 1: according to a kind of nontoxic biological antifouling coating of the present invention, comprise epoxy resin with light transmission, varnish, auxiliary agent, fat-soluble luminous powder, curing agent, each component is respectively by weight percentage: 40% oxygen resin, 10% varnish, 36% additives, 10% luminous powder, 4% curing agent, the luminous powder contains non-toxic and non-radiative alkaline earth aluminosilicate excited by rare earth elements. The non-toxic biological antifouling paint of this embodiment has a good antifouling effect after being placed on the surface of the substrate by the treatment method of the present invention, and can achieve the purpose of the present invention.
Embodiment 2
[0030] Embodiment 2: Another kind of non-toxic bio-antifouling coating of the present invention comprises polyurethane resin with light transmission, varnish, auxiliary agent, fat-soluble luminous powder, curing agent, and each component is respectively by weight percentage: polyurethane resin 38%, varnish 8%, auxiliary agent 30%, luminous powder 20%, curing agent 4%, the luminous powder contains non-toxic and non-radiative alkaline earth aluminosilicate excited by rare earth elements. The non-toxic biological antifouling paint of this embodiment also has a good antifouling effect after being placed on the surface of the substrate by the treatment method of the present invention, and can achieve the purpose of the present invention.
Embodiment 3
[0031] Embodiment 3: another kind of non-toxic biological antifouling coating of the present invention, comprises amino varnish with translucency, varnish, auxiliary agent, fat-soluble luminous powder, curing agent, and each component is respectively by weight percentage: amino varnish 35%, varnish 6%, auxiliary agent 25%, luminous powder 30%, curing agent 4%, the luminous powder contains non-toxic and non-radiative alkaline earth aluminosilicate excited by rare earth elements. The non-toxic biological antifouling paint of this embodiment, after being placed on the surface of the substrate by the treatment method of the present invention, also has a good antifouling effect, and can also achieve the purpose of the present invention.

Abstract
The invention provides a nontoxic biological antifouling coating which comprises a resin binder, a varnish, an additive, a curing agent and a liposoluble noctilucent powder, wherein the resin binder has better light transmittance. The invention also provides a preparation method of the nontoxic biological antifouling coating and a method for treating the surface of a substrate by utilizing the nontoxic biological antifouling coating. Based on the nontoxic biological antifouling coating, environment illumination is provided day and night mainly through noctilucent materials, thereby lowering the attachment of marine organisms by utilizing the photo inhibition effect; the noctilucent powder is alkaline earth aluminosilicate excited by a rare earth element without toxicity orradiation, thereby reducing the ill effect to the environment. The invention can also realize biological antifouling in different degrees and different environments by changing the concrete proportion of the noctilucent powder and each component and is suitable for different working conditions. The manufacture cost and the maintenance cost of the nontoxic biological antifouling coating are both relatively low.
Description
technical field [0001] The present invention relates to a biological antifouling paint, a preparation method of the biological antifouling paint, and an antifouling treatment method, more specifically, to a non-toxic biological antifouling paint containing luminous powder, the non-toxic A preparation method of a biological antifouling paint, and a method for antifouling treatment of a substrate by using the non-toxic biological antifouling paint containing luminous powder. Background technique [0002] On various artificial surfaces, the attachment, growth, and reproduction of organic life forms have brought many disadvantages, and this phenomenon is collectively referred to as biofouling. Biofouling in the marine range can lead to many disadvantages, such as increased energy consumption, reduced efficiency, and increased corrosion of marine vessels. Regardless of civil, commercial or military use, marine antifouling is an important issue in marine engineering. Marine foul...
