Abstract

The invention relates to a normal temperature metal cleaner as well as a preparation process thereof. The cleaner comprises the following components by weight: 6 to 8 parts of amphoteric surfactant; 0.2 to 0.4 parts of potassium permanganate; 1 to 2 parts of emulsifying agent; 4 to 8 parts of oxalic acid; 10 to 20 parts of acid fog inhibitor; 5 to 10 parts of triethanolamine oleate; 2 to 4 parts of surface conditioning agent; 3 to 6 parts of pickling inhibitor; 50 to 100 parts of hydrochloric acid with concentration of 31 to 36 percent; and 20 to 40 parts of water. Compared with the prior art, the normal temperature metal cleaner and the preparation process thereof have the advantages of: 1. convenience: the product is applied to the cleaning of various metallic products, and is simple and convenient in operation. 2. High efficiency: the operation process is simple, and the cleaning efficiency is greatly improved. 3. Economy: surfaces of various metal workpieces can be effectively cleaned and treated, the consumption of cleaner is low, and the production speed is expedited for users. 4. Environmental protection: the cleaner has no acid mist and is safe for human body.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a normal-temperature metal cleaning agent and a preparation process thereof. Background technique [0002] Metal cleaning agent is a kind of surface detergent compounded by various surfactants. It can remove oil and dirt, and make the surface of the workpiece clean and dry. At present, the metal cleaning agents used to remove oil stains on the metal surface are usually medium-temperature or high-temperature metal cleaning agents, and this type of metal cleaning agent has one of the biggest defects, which is that it needs to be heated. If it is heated with an electric heating rod The cost is high. If you switch to a coal furnace for heating, it will affect the environment and you must pay a certain cost. How to achieve the same effect of removing oil on the metal surface without heating has always been the direction of people's research. Although there are room-temperature metal ...
