Embodiment Construction

[0021] In order to make the content of the present invention more obvious and understandable, the present invention will be described in detail below in conjunction with specific examples 1-4.

[0022] A two-component interfacially bonded silicone tie paint supporting fouling-release antifouling paint, made of component A and component B at a weight ratio of 10:1, the component A is composed of silicone, pigment Composed of filler, solvent and thixotropic agent, component B of high toughness curing agent and reaction accelerator, the dosage of each component in terms of weight percentage is 35~55% of component A silicone, 20~40% of pigment and filler, and 15% of solvent ~30% and 0~5% of thixotropic agent and 10~20% of component B high toughness curing agent and 0.01~0.03% of reaction accelerator.

[0023] The organosilicon is a mixture of hydroxyl silicone oil and epoxy silicone oil, and the weight ratio of hydroxyl silicone oil and epoxy silicone oil is 1:0.6-1.5. The high-t...

Abstract

The invention discloses bi-component interfacial bonding organosilicone connection paint matched with pollution release type anti-fouling paint. The bi-component interfacial bonding organosilicone connection paint is prepared from a first component and a second component according to the weight ratio of 10:1. The first component is prepared from organosilicone, pigments and filler, a solvent and a thixotropic agent. The second component is prepared from a high-toughness curing agent and a reaction promoter. The bi-component interfacial bonding organosilicone connection paint is prepared from the first component including, by weight, 35-55% of organosilicone, 20-40% of pigments and filler, 15-30% of solvent and 0-5% of thixotropic agent and the second component including, by weight, 10-20% of high-toughness curing agent and 0.01-0.03% of reaction promoter. According to the connection paint, the problem that pollution release type anti-fouling paint and anti-rusting paint are poor in adhesive force is solved, the adhesive strength to an anticorrosion coating reaches 2.2 MPa or above, the connection strength for an anti-fouling coating reaches 1.3 MPa or above, and 100% cohesive failure is shown; after being scoured by 50 sections of high-speed flow for 1,000 hours, the coatings are free of bubbling, disengaging and cavitation damage, and have good adhesive performance.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a two-component interface-bonded organic silicon connecting paint matched with a fouling release type antifouling paint. Background technique [0002] The supporting system of coatings in areas below the waterline of ships today mainly includes anti-corrosion coatings / connecting coatings / anti-fouling coatings. Because the resin base materials used for anti-corrosion coatings and anti-fouling coatings are different, the adhesion between the two coatings will be weaker. Low, in order to solve this problem, a layer of transition paint is usually applied between the two coats. At present, the connecting paints that are widely used at home and abroad mainly include epoxy connecting paint, vinyl connecting paint and chlorinated rubber connecting paint. However, these tie paints are mainly suitable for rigid coatings and have good adhesion to antirust primers, bu...
