Description
Technical field
The present invention relates to aqueous cutting fluid field, ether carboxylic acid built agent, system in particular to a kind of aqueous cutting fluid
Preparation Method and aqueous cutting fluid.
Background technology
Water-base cutting fluid includes synthetic cutting fluid, semi-synthetic cutting fluid and emulsion.In use, it is cutting fluid is former
Liquid is configured to dilution and is used with water.Water typically contains some mineral matters, and these mineral matters are without hardness salt (such as potassium, sodium)
With hardness salt (such as calcium, magnesium).The hardness of water is exactly the number according to contained hardness mineral matter in water to be calculated.The hardness of water can divide
Be three-level, i.e. soft water (＜ 150ppm), middle hard water (150~300ppm) and hard water (＞ 300ppm).The hardness of water is low, uses liquid
Then easily foaming；The hardness of water is high, using liquid then easy graining, over time, is then easily layered using liquid, influences its life-span.
Hard water may also be some of concentrate active ingredient and be separated out from dilution, condenses and precipitates.Particularly in cutting fluid it is cloudy from
Sub- surfactant, easily generates water insoluble metallic soap in hard water so that a part of concentrate is consumed for softened water,
Cutting fluid cannot be played a part of.To ensure cutting fluid performance, many addition concentrates are needed, so as to increased cost.
Aqueous cutting fluid is general by antirust acid, PH regulators, metal inhibitor, antibacterial additives, mineral oil, lubrication addition
Agent, EP agent, hard water resistance additive, the composition such as emulsifying agent and water.The water hardness of northern China is generally higher, if
General water-base cutting fluid is used, and can all occur using liquation soap, or even condensate oil soon, ultimately results in water-oil separating, is shortened
The service life of product.Current hard water resistance additive has EDETATE SODIUM salt, ether carboxylate, phosphino- polycarboxylic acids etc..EDETATE SODIUM salt is one
Kind of metal shadowing agent, there is a network and ability to calcic hard water in the range of various PH and under various concentration, and at PH >=8 efficiency
Highest, with calcium metal with 1：1 mol ratio network and, to the excellent stability of heat in water, or even in superheated water, will not also divide
Solution, is a kind of effectively water softening agent.But it can only cure the symptoms, not the disease, so it is not recommended that addition.Ether carboxylate and phosphine
The addition such as based polycarboxylic acid is very big to hard water resistance impact effect, is currently relatively good selection.By studying different types of ether
The hard water resistance performance of carboxylate, addition is more, then the foam using liquid is big；Addition is few, then using liquid hard water resistance effect not
It is preferable.
