Problems solved by technology

[0003] Existing degreasing agents mainly use high temperature (60-90°C), which requires a lot of heat energy to heat; and contain strong alkaline corrosive substances, which are inconvenient to operate and require high personnel protection. After degreasing, cleaning requires a large amount of water to clean; Contains surfactants, which will produce a lot of foam when cleaning after degreasing, polluting the environment

Embodiment 1

[0012] Wherein, the amphoteric active agent is sodium octylamine propionate. The defoamer is alcohols, specifically propylene glycol.

[0013] During preparation, the above-mentioned components are prepared according to the quality of the degreasing agent. The specific preparation method is: sequentially add sodium carbonate, sodium tripolyphosphate, sodium dodecylbenzenesulfonate, sodium octyl sulfate, Sodium octylamine propionate, defoamer, and finally add water to 1 liter and stir to mix well.

[0014] Embodiment 2: a kind of degreasing agent of the present invention, comprises the component of following parts by weight: 30 parts of sodium carbonate, 10 parts of sodium tripolyphosphate, 1 part of sodium dodecylbenzenesulfonate, 16 parts of octylsulfuric acid Sodium, 68 parts amphoteric agent, 0.5 part defoamer.

Embodiment 2

[0015] Wherein, the amphoteric active agent is octyl betaine. The defoamer is ethers, specifically diethyl ether.

[0016] During preparation, the above-mentioned components are prepared according to the quality of degreasing agent. The specific preparation method is: add sodium carbonate, sodium tripolyphosphate, sodium dodecylbenzenesulfonate, sodium octyl sulfate, octyl Base betaine, antifoaming agent, and finally add water to 1 liter and stir to mix well.

Abstract

The present invention discloses a formula of a low-alkali and low-foam deoiling agent at a room temperature. The low-alkali and low-foam deoiling agent comprises, by weight, 25-30 parts of sodium carbonate, 8-10 parts of sodium tripolyphosphate, 1-7 parts of sodium dodecylbenzene sulfonate, 13-16 parts of sodium octyl sulfate, 50-68 parts of an amphoteric activator, and 0.1-0.5 part of a defoamer. According to the present invention, the sodium octyl sulfate and the amphoteric activator are adopted, such that the low-alkali and low-foam deoiling agent has the deoiling effect at the room temperature; and the defoamer is added, such that the low-alkali and low-foam deoiling agent has characteristics of low alkali, low foam and environmental protection, and the production cost is reduced.

Description

technical field [0001] The invention relates to a low-alkali and low-foam degreasing agent at normal temperature, which is suitable for pretreatment before electroplating on metal surfaces. Background technique [0002] Degreasing agent is a complex mixture of organic and inorganic chemicals in water base, and is a new type of industrial degreasing agent developed by using the principle of "emulsification" and "saponification". Degreasing agents are divided into metal degreasing and plastic degreasing. [0003] Existing degreasing agents mainly use high temperature (60-90°C), which requires a lot of heat energy to heat; and contain strong alkaline corrosive substances, which are inconvenient to operate and require high personnel protection. After degreasing, cleaning requires a large amount of water to clean; Contains surfactants, which will produce a lot of foam when cleaning after degreasing, polluting the environment. Contents of the invention [0004] Purpose of the ...
