Normal temperature degreasing agent

Abstract

The invention provides a normal temperature degreasing agent which is prepared into aqueous solution in a container by weight percent. The aqueous solution comprises the following components in percentage by weight: 14.23-15.02% of octyl polyoxyethylene ether, 4.22-4.4% of polyvinyl alcohol 400, 6.4-6.51% of octadecyl dimethyl amine oxide, 2.83-2.9% of unsaturated fatty acid, 0.66-0.79% of 2-ethyl hexanol, 5.33-5.47% of triethanolamine, 0.16-0.21% of 2-amino-2-methyl-1-propyl alcohol, and the balance of water. The invention has the advantages: (1) heating is not needed when the temperature is above 8 DEG C, the operation is easy with no need of other auxiliary equipment, and the agent is environmental friendly; and (2) equipment maintenance is omitted, the consumptions of the two types of degreasing agents are the same, and the cost can be greatly saved by using the normal temperature degreasing agent.

Description

technical field [0001] The invention relates to the chemical field of metal surface degreasing, in particular to a normal temperature degreasing agent. Background technique [0002] The surface of mechanical parts needs to be sprayed with paint to make it a qualified product, especially the body of a car. After spraying, the body can be distinguished in different colors; The surface is degreased, but the common degreasing agent has several major disadvantages: A. It needs to be heated, consumes energy, and pollutes the environment. For example, the heating power of 2 degreasing tanks is 140kw, and the heating time is calculated as 4h a day, 140kw×4h=560kw .h, 560kw.h × 1.00 yuan / day = 560 yuan / day, 560 yuan / day × 300 days = 168,000 yuan / year, and the toxic gas after heating will cause harm to the human body, and the waste liquid will pollute the environment; B. Increase equipment investment; C. Increase maintenance workload; heating 40-60 ℃, energy consumption; degreasing b...

Increase equipment investment; C. Increase maintenance workload; heating 40-60 ℃, energy consumption; degreasing bath temperature is low, degreasing is not clean, the technical department must be controlled
