Problems solved by technology

The surface phosphating treatment process of iron and steel workpieces was developed in the 1950s. After half a century of exploration and development, a relatively complete technology and reliable production process have been formed. It plays an important role. Due to the complex production process, the one-time investment in equipment is relatively large, and it must be equipped with sewage treatment facilities, the production cost is high. It has not been widely used in my country's small and medium-sized machining and manufacturing industries.

Embodiment 1

[0008] The following are non-limiting examples of the present invention: Embodiment 1: take H 3 PO 4 33 parts, 15 parts of aluminum powder, NH 4 NO 3 1 part, AlK(SO 4 ) 2 0.05 parts, water (H 2 O) 50 parts (all are parts by weight), H 3 PO 4 33 parts and 15 parts of aluminum powder were mixed, fully reacted to prepare aluminum phosphate liquid for later use, and then NH 4 NO 3 1 part, AlK(SO 4 ) 2 0.05 parts, water (H 2 O) 50 parts are mixed evenly with the prepared phosphoric acid solution to obtain the water-emulsion type rust-removing and anti-rust solution of the present invention. The water-emulsion type rust-removing and anti-rust liquid of the present invention is used for the steel ball of 15 meters of diameters on the roof of a building for experiment, removes floating rust with wire brush before painting, brushes two layers with this bright water-emulsion type rust-removing and anti-rust liquid, and then After being covered with varnish for decoration...

Embodiment 2

[0009] Embodiment 2: take H 3 PO 4 34%, aluminum (Al) powder 13%, NH 4 NO 3 1%, AlK(SO 4 ) 2 0.1%, water (H 2 O) 51.9% prepare 5 tons of water-emulsion type rust-removing and anti-rust liquid of the present invention and be used for the immersion type rust-removing and anti-rust liquid of iron and steel parts. There are only 2 procedures, that is, soaking for 5-20 minutes (rust removal, rust prevention and phosphating) and natural drying. The product can be 100% utilized. The product is colorless, transparent, non-volatile, and PH=0.5. After the original solution has been used for many times, if the pH value is greater than 1, only the original solution needs to be added to make the pH ≤ 1, then it can continue to be used. affect the quality. Basically realized "zero discharge" of pollution and improved the production conditions of operators.

Abstract

An aqueous emulsion type rust-removing and anti-rust liquid is prepared from H3PO4, Al powder, NH4NO3, Alk(SO4)2, and water through proportioning, mixing H3PO4 with Al powder, reaction to obtain aluminium phosphate solution, mixing it with others, and regulating pH value to 0.5-1. Its advantages are high effect, no damage to human body, and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of metal material surface chemical treatment, and relates to a water-emulsion type rust-removing and anti-rust liquid and a manufacturing method thereof. Background technique [0002] When the traditional paint is painted on the steel surface, it must be completely derusted, and even the metallic luster must be completely exposed. The labor intensity is high, the production efficiency is low, the construction cost is high, and the rust dust seriously endangers human health, especially for large-scale equipment projects, such as ships, bridges, offshore oil production facilities, heavy machinery, etc., due to the long construction period, often the original If the pre-painted primer is damaged, and the rust is re-rusted, a second derusting must be carried out. Rust paint is a new type of paint that can be directly painted on the surface of residual rusted steel. It has been studied abroad since the 1950s and...
