Bi-component corrosion-proof dope

Abstract

A titanium-nickel nanometer alloy powder contains A and B components; A components consist of epoxy-resin, titanium-nickel nanometer alloy powder, antirust pigment, filler corrosion stabilizer and anti-sagging accessory; B components consist of composite curing agent with cashew nut shell modified phenolic amine curing agent and polyamide epoxy curing agent; the proportion of A and B is 10:1. It has excellent adhesion and physical performance and better oil, water, acid-alkali and salt fog resistances and mating ability. It can be used as universal base coat and used for various substrate materials such as steel, aluminum and stainless steel etc.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to a high-performance anti-corrosion primer suitable for various parts of a ship, suitable for various base materials and not affected by seasons during construction. Background technique [0002] Regular and timely implementation of anti-corrosion and anti-rust treatment on ships is an important part of ship maintenance, and it is necessary to apply corresponding anti-rust and anti-corrosion coatings to various parts of the ship. Different parts of the ship's bottom, deck, and hull are in different environments and conditions during the use of the ship, and the requirements and operating conditions for coatings are also different. Therefore, special coatings are currently used for different parts. For example, ship bottom anti-rust paint is a special coating applied on the bottom of the ship below the waterline, and its main purpose is to prevent the corrosion of the steel plate. Since...

AI Technical Summary

Problems solved by technology

This type of coating has excellent water resistance and good performance-price ratio, but at the same time there are fatal shortcomings: a large amount of coal tar pitch is added to the film-forming material, accounting for more than 40% of the total; It will cause great harm to human body and environment

In addition, this type of coating has serious precipitation and poor storage stability; the coating is affected by the construction environment and temperature, and cannot be used for normal curing below 5°C in winter in the Beihai area

[0004] Looking at the varieties of domestic coatings, there is no anti-corrosion coating with excellent anti-corrosion performance, four-season curing, high performance and low surface treatment requirements with substrate adaptability and topcoat compatibility.
