Embodiment 1～3

[0047] Antifouling paint: See Table 1 for the formulation. (weight percent)

[0048] Table 1

[0049]

[0050] The distribution ratio of Group A and Group B is (8-12): 1, and the specific calculation and actual test shall prevail.

[0051]The antifouling agent in the embodiment is silver-copper ion nanocomposite powder of α-zirconium phosphate, and adopts the product of NAFUR series antifouling agent produced by Shanghai Runhe Nano Material Technology Co., Ltd.;

Embodiment 1

[0052] Embodiment 1 preparation method:

[0053] Preparation of antifouling paint:

[0054] (1) Heat and dissolve epoxy resin and 18% solvent by total weight, add wetting and dispersing agent, rosin resin, anti-rust pigment, 3% solvent by total weight, other additives in turn, grind, add dispersed anti-fouling Add the anti-sedimentation agent silicon dioxide and the rest of the solvent to obtain component A. The rotational viscosity of component A at 25°C is above 1.0pa.s;

[0055] (2) Mix polyamide epoxy curing agent and solvent, stir and mature to obtain component B;

[0056] The weight ratio of components A and B is that the ratio of the epoxy equivalent of component A to the active hydrogen equivalent molar ratio of component B is 1:1. After mixing components A and B, use them up within 4 hours.

[0057] The preparation method of embodiment 2~3 is with embodiment 1, wherein:

[0058] The preparation method of antifouling paint is as follows:

[0059] Heat and dissolve ...

Abstract

The invention discloses contact type inshore fishing boat anti-fouling paint and a preparation method thereof. The contact type inshore fishing boat anti-fouling paint comprises a component A and a component B, wherein the component A comprises the following components in percentage by weight: 10%-30% of epoxy resin, 0-15% of rosin resin, 3%-15% of anti-rusting pigments, 15%-25% of an anti-fouling agent, 0.2%-1.0% of fumed silica, 0.2%-1.5% of an aid, 5%-30% of functional pigments and 15%-40% of a solvent; the component B comprises the following components in percentage by weight: 60%-100% of an epoxy curing agent and 0-40% of a solvent. The contact type inshore fishing boat anti-fouling paint has the advantages that the anti-fouling paint does not contain internationally forbidden pesticide poisons such as organic tributyltin (TBT) and dichlorodiphenyltrichloroethane (DDT); the manufacturing and construction environments are relatively good, the poisons and resin emitted to ocean are reduced; the contact type inshore fishing boat anti-fouling paint is environmentally friendly and is non-toxic to the environment.

Description

technical field [0001] The invention relates to an antifouling paint, in particular to a general-purpose high solid content contact type ship bottom antifouling paint, which can be used for the contact part between the bottom of a steel ship hull and water. Background technique [0002] In recent years, shipbuilding, shipping, offshore oil and gas development, and mariculture have flourished, but various marine attached organisms have brought great harm to humans in the process of developing the ocean. For example, barnacles, seaweed, and shellfish are attached to the bottom of ships, buoys, wharves, piers, seawater pipelines, and cage nets in large numbers. Their huge number and extremely fast growth speed can slow down the speed of ships and increase fuel. , Accelerate metal corrosion, block pipes and cage mesh, make underwater facilities unbalanced, etc. [0003] Among the methods to prevent marine organisms from attaching and fouling ships and various facilities, the mo...
