Cleaning agent for oil stain on electronic device

Abstract

The invention relates to an oil stain washing agent for an electronic device. The oil stain washing agent comprises the following compositions by weight percentage: 3 to 10 percent of silicate, 5 to 10 percent of phosphate, 5 to 10 percent of a surface active agent, 1 to 6 percent of a pH conditioning agent, 10 percent of polyoxyethylene, 2 to 5 percent of alkylphenol ether, and the balance being de-ionized water. The oil stain washing agent has the advantages that: 1) the washing agent does not contain nitrite which is harmful to human body and environment, and the surface of a part which is washed by the washing agent can form a compact protective film, thereby ensuring that the washed part has a function of rust prevention; 2) the washing agent has a simple production process by mixing the raw materials at normal temperature without special equipment, has strong washing capability and short washing time, saves labor power and time, and has efficacy of rust removal and rust prevention; and 3) the washing agent is water soluble, and waste fluid after washing is convenient for treating and discharging, and accords with the requirement of environmental protection.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based electronic device oil cleaning agent. Background technique [0002] Electronic devices need to be cleaned before processing, and the amount of ordinary mechanical parts prepared by electronic devices and precision components used in other fields is quite large, so the workload of cleaning such metal parts is correspondingly large. The amount of cleaning agent required in the cleaning process must also be quite large. With the stringent environmental protection requirements and standards, the discharge control of industrial wastewater is becoming more and more stringent. Therefore, the discharge of a large number of waste cleaning agents has become an important topic for this industry to study. In addition, most of the existing oil cleaning agents for electronic devices are solvent-based, phosphorus-containing water-based cleaning agents, etc. The disadvantages of these cleaning ...

Problems solved by technology

In addition, most of the existing oil cleaning agents for electronic devices are solvent-based, phosphorus-containing water-based cleaning agents, etc. The disadvantages of these cleaning agents are that the cleaning effect is not very ideal, and the electronic devices after cleaning are prone to black surface layers, which is difficult for subsequent processing. It brings trouble, especially for the processing of precision components; it is highly corrosive to equipment and increases the cost of equipment; it takes a long time to clean, and it takes 10 to 30 minutes to clean
