Environment-friendly quick-drying water-based antirust agent and preparation method thereof

Abstract

The invention relates to the technical field of water-based antirust agents, in particular to an environment-friendly quick-drying water-based antirust agent and a preparation method thereof. The antirust agent comprises the following components of, in parts by weight, 170-220 parts of sodium silicate, 35-50 parts of deionized water, 9-14 parts of rust remover, 5-8 parts of sodium phosphate powder, 4-6 parts of straight iron wires, 1-2 parts of triethanolamine, 2-4 parts of boric acid, 0.1-0.3 part of ethylenediamine tetraacetic acid and 0.7-1.1 parts of sodium tungstate; and before the antirust agent is smeared on a metal surface prone to be rusted, rust on the metal surface needs to be treated, so that the field operation is inconvenient. According to the antirust agent, pre-smeared glue, combined liquid and film-forming particles in the water-based antirust agent are matched with each other, the metal rust attached in a pre-smeared glue smearing process is separated through the combined liquid, then under the heating effect of dissolving of the sodium phosphate powder in the film-forming particles, the rust dissolved in the sodium silicate is separated out under the action of gravity, and therefore, the rust removing operation required before the antirust agent is smeared is avoided, and the use effect of the environment-friendly quick-drying water-based antirust agent is improved.

Description

technical field [0001] The invention relates to the technical field of water-based antirust agents, in particular to an environment-friendly and quick-drying water-based antirust agent and a preparation method thereof. Background technique [0002] Water-based anti-rust agent is a water-based anti-rust solution, which can effectively protect steel, iron and other materials from rusting. According to different anti-rust period requirements, it is mixed with water in a certain ratio to achieve the purpose of prolonging its storage or service life. At present, the commonly used metal anti-corrosion measures on the market are anti-rust agents, and anti-rust agents are divided into anti-rust oils , anti-rust emulsion and water-based anti-rust agent, etc. Among them, the water-based anti-rust agent does not affect the appearance and touch of the metal surface, coupled with the improvement of people's environmental protection awareness and the consideration of economic interests, s...

Problems solved by technology

[0003] Before the antirust agent is applied to the rust-prone metal surface, the rust should be treated and the surface should be polished to a degree of brightness, so as to ensure that the applied water-based antirust agent can form an effective protective film, but at the same time it increases The use steps of anti-rust agent are not convenient for on-site operation

[0004] In the prior art, there are also some technical solutions about environmental-friendly and quick-drying water-based rust preventives and their preparation methods. For example, a Chinese patent with application number 2018104110259 discloses an environmentally-friendly and quick-drying water-based rust preventive and its preparation The method includes a main corrosion inhibitor, an auxiliary corrosion inhibitor, a film-forming agent, a thickener, a penetrating agent, and a defoamer, wherein, in terms of parts by mass, the content of the film-forming agent is 3 to 10 parts, and the The content of the penetrating agent is 10-30 parts, the content of the thickener is 2-5 parts, the content of the auxiliary corrosion inhibitor is 30-45 parts, the content of the main corrosion inhibitor is 30-50 parts, the content of the disinfectant The content of the foaming agent is 1-3 parts; the water-based anti-rust agent of this technical scheme volatilizes quickly after being distributed on the metal surface, and can be dried in about 20 minutes at room temperature, which is much faster than the drying time of water-based anti-rust agents on the market (about 3~8h); after drying, it is colorless and transparent film, so it is suitable for metals of various colors; due to fast volatilization, it is evenly distributed on the metal surface, without sag phenomenon, and it is not easy to be returned during metal storage or transportation. The uneven distribution of active ingredients is caused by scraping before it is completely dry; however, this technical solution does not solve the problem that the rust inhibitor needs to be pre-treated before using it on metal, which will affect the use of the rust inhibitor. the convenience problem
