Embodiment

[0014] A method for making a composite repair agent for cement machinery, comprising the following steps:

[0015] S1. Stir and mix 10g ethylene glycol, 2g calcium chloride and 12g glycerol for 30 minutes to prepare reagent A for use;

[0016] S2. 0.2g hydrochloric acid, 1g methacrylic acid, 1.5g polyaluminum chloride, 0.8g triethanolamine, 2g hexamethylenetetramine, 5g urea, 10.1g sodium chloride, 7.5g sodium molybdate and 0.2g phosphoric acid Add it into 500ml distilled water and stir it thoroughly for 30 minutes to make ready-to-use reagent B;

[0017] S3. Add 2g of citric acid and 5g of sodium dodecylbenzenesulfonate into 500ml of distilled water, and stir well for 10 minutes to make an activator;

[0018] S4. Add the reagent A to the reagent B, and fully stir for 30 minutes to make a mixed solution;

[0019] S5. Pour the activator into the mixed solution, stir evenly, and let it stand for 120 minutes to complete the production of the composite repair agent.

Abstract

The invention discloses a compound repair agent for cement machinery and a preparation method thereof. The compound repair agent is prepared from ethanediol, calcium chloride, glycerin, hydrochloric acid, methylacrylic acid, polyaluminum chloride, triethanolamine, citric acid, hexamethylene tetramine, sodium dodecyl benzene sulfinate, urea, sodium chloride, sodium molybdate and phosphoric acid. The compound repair agent for cement machinery can remove rust efficiently, and improves rust resistance, antifreezing ability and corrosion resistance of the surface of the cement machinery greatly. Meanwhile, the preparation method of the compound repair agent for cement machinery is simple and explicit and low in cost, and has extremely good partiality and beneficial effects.

Description

technical field [0001] The invention relates to the field of mechanical repair agents, in particular to a composite repair agent for cement machinery and a preparation method thereof. Background technique [0002] Because of its large size, cement machinery is usually installed outdoors, and long-term wind and rain will cause serious corrosion and damage to its surface. After the surface of these cement machinery is damaged, it is difficult to maintain. Therefore, it is necessary to configure a special repair agent for it to achieve the purpose of rust removal, rust prevention, frost resistance and corrosion resistance. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a composite repair agent for cement machinery and a preparation method thereof. Spraying the composite repair agent on the cement machinery can effectively remove rust and increase its anti-corrosion. Rust,...
