Embodiment 1

[0041] Add 75kg of E-42 resin, 15kg of P120h modified petroleum resin, 17kg of xylene, and 8kg of butanol into the reaction pot and heat and stir until uniform. The temperature is controlled at 65°C to make it a uniform transparent liquid until the solid content is 75%.

[0042] Add 35kg of the above-mentioned E-42 resin liquid, 2kg of APA organic bentonite, 5kg of titanium dioxide, 15kg of precipitated barium sulfate, 15kg of quartz powder, 0.5kg of AT-U additives, and 11kg of mica powder into the adjustment cylinder and stir and mix, and then sand mill After machine grinding to a fineness of ≤60 μm, add 5kg of xylene and 2kg of butanol to adjust the viscosity to 5.5±2.5Pa·s, filter and pack it with an 80-mesh sieve as component A.

[0043] Mix 50kg of 650 polyamide curing agent, 15kg of NX-2040 cashew nut oil modified epoxy curing agent, and 35kg of xylene to a uniform liquid, then subpackage and pack it into component B, and use it according to the weight ratio of 2 :1 Mix ...

Abstract

The invention provides double-component epoxy resin anticorrosive paint and a preparation method thereof. Component A comprises the compositions by weight percentage of 15-25 percent of epoxy resin, 10-20 percent of modified petroleum resin, 30-40 percent of pigment, 2-5 percent of fillers, 5-6 percent of promoter and 10-20 percent of solvent. Component B comprises the compositions by weight percentage of 50-60 percent of polyamide curing agent, 10-20 percent of modified cashew oil curing agent and 30-40 percent of solvent. The viscosity of the component A is 3.0-8.0Pa.s. The weight ratio of component A to component B is 2-6 to 1. The paint contains no coal tar pitch. Damages to human bodies and the environment are greatly reduced. One-time thick membrane spraying construction can be implemented. And the paint has good chemicals resistance and corrosion resistance, can be used as paint for ballast water tank and accords with requirements of IMO convention. The process method has the advantages of convenience, simplicity, energy saving performance and low cost. Good membrane forming performance and good storing stability can be shown at room temperature.

Description

technical field [0001] The invention relates to an epoxy antirust paint capable of thick film coating and a preparation method thereof. Background technique [0002] Epoxy asphalt antirust paint is widely used in ship bottoms, ballast water tanks, wharf steel piles, Offshore oil drilling platforms, hydraulic steel gates, mine steel supports, inner and outer walls of pipelines, etc. are used as heavy anti-corrosion coatings. However, the coal tar pitch contains volatile substances such as benzene, anthracene, and naphthalene, which are potentially harmful to humans and the environment. Contents of the invention [0003] The purpose of this invention is to provide a kind of two-component epoxy resin type antirust paint and preparation method, to overcome the above-mentioned defect that prior art exists. [0004] The two-component epoxy resin type antirust paint provided by the present invention comprises A and B components, and the weight percent components of A component ...
