Energy-saving and anticorrosive seal primer and preparation method thereof

Abstract

The invention provides an energy-saving and anticorrosive seal primer and a preparation method thereof, and relates to the field of coatings. The energy-saving and anticorrosive seal primer comprisesthe following components: 14 to 42 parts of vinyl acetate, 12 to 15 parts of acrylic acid, 15 to 30 parts of industrial alcohol, 0.1 to 0.3 part of n-butyl acrylate, 5 to 6 parts of an anticorrosive pigment, 2 to 10 parts of an auxiliary agent and 100 to 200 parts of zinc powder. The energy-saving and anticorrosive seal primer provided by the invention can provide good corrosion resistance. The preparation method for the energy-saving and anticorrosive seal primer comprises the following steps: dissolving the auxiliary agent into the industrial alcohol so as to form a first mixed solution; adding acrylic acid, vinyl acetate, the anticorrosive pigment and n-butyl acrylate into the first mixed solution, and carrying out uniform mixing so as to form a second mixed solution; pouring the secondmixed solution into a reaction vessel, and carrying out heating so as to prepare copolymer resin; and cooling the copolymer resin, then adding the zinc powder by weight, and carrying out uniform mixing under stirring with a stirrer. The method provided by the invention is simple, convenient and fast, and has strong operability and great industrial popularization values.

Description

technical field [0001] The invention relates to the field of coatings, and in particular to an energy-saving and corrosion-resistant sealing primer and a preparation method thereof. Background technique [0002] So far, China's steel output ranks first in the world, and the annual steel consumption caused by steel corrosion is equivalent to about 10-20% of the total steel production in that year. The direct economic loss caused by steel corrosion accounts for about 6% of the gross national product. Corrosion of steel brings not only a series of shocking economic losses, but also corrosion of commonly used steel components such as roads, housing, bridges and other structural Property damage and personal injury. [0003] Among them, metal corrosion is the most common form of corrosion. When rust occurs, chemical and electrochemical reactions will occur on the surface of the metal, so that the metal elements are converted from atoms into oxidized ions. This will seriously r...

Problems solved by technology

At present, the most common and most important anti-corrosion and shop primer for steel structures is zinc-rich sealing primer, but the sealing primer in the prior art still has the problems of high energy consumption and weak anti-corrosion performance.
