Description
Technical Field
The invention belongs to the technical field of cleaning agents, relates to a soft metal cleaning agent, and particularly relates to a non-VOC soft metal cleaning agent.
Background
Metal cleaners can be broadly classified into three types, organic solvent cleaners, water-based cleaners and semi-water-based cleaners, according to the water content of the chemical cleaner. Among them, water-based metal cleaners have become the development of modern metal cleaners due to their reliable safety, environmental protection and excellent cleaning ability.
VOCs are acronyms for volatile organic compounds (volatile organic compounds). VOCs in the general sense are commanding organic matters; but the definition in the environmental protection sense refers to an active class of volatile organic compounds, namely, volatile organic compounds which can cause harm. VOC emission has great influence on human health, and the VOC emission is more and more concerned with the development of the society.
In addition, various auxiliary agents are often required to be added into the water-based soft metal cleaning agent, some of the auxiliary agents are small molecular compounds, such as ethylene glycol butyl ether commonly used as a solubilizer, the components can generate VOC emission, the VOC emission has great influence on the physical health of workers, the VOC emission requirements of various countries are customized according to corresponding standards, and the VOC emission of developed countries is stricter.

As a further improvement of the technical scheme, the terpineol-based sulfate is represented by the structural formula
Wherein M is Na or K.
Further, the terpineol-based sulfate is synthesized by the following method:
the terpineol and chlorosulfonic acid with the molar ratio of 1:1 are sulfated at normal temperature, slowly added into ice water, alkalized by adding an aqueous solution of sodium hydroxide or potassium hydroxide, the pH value is adjusted to 7-8, and water is evaporated to obtain the terpineol sulfonate.
The terpineol-based sulfate provided by the invention has a hydrophilic group at one end and a lipophilic group at one end, and although a hydrophobic chain which is long enough like a surfactant is not provided, the hydrophilic and lipophilic characteristics of the terpineol-based sulfate still have very high solubilizing effect on components which are difficult to dissolve in water.
The non-VOC water-based soft metal cleaning agent adopting the technical scheme has the following beneficial effects:
the cosolvent is terpineol-based sulfate, compared with other solubilizers with small molecular structures, the cosolvent does not generate VOC (volatile organic compound) emission, other components do not generate VOC emission, the cosolvent is harmless to a human body, the harm to the body of workers in the operation process is reduced, the cosolvent can be biodegraded by adopting the green and environment-friendly surfactant alkyl glycoside, and the cleaning agent has strong cleaning capacity which is up to more than 90%.
Detailed Description
The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown.
Example 1: synthetic terpineol alcohol-based sulfate
100g of terpineol is added into a three-neck flask provided with a hydrogen chloride absorption device, a thermometer and a stirrer, the temperature is controlled to be 25-30 ℃, 75.5g of chlorosulfonic acid is slowly dripped by a dropping funnel under stirring, the dripping temperature is not more than 30 ℃, the dripping time is not less than 1.5 hours, after the addition is finished, the stirring reaction is continued for 2 hours at 25-30 ℃, and hydrogen chloride gas generated by the reaction is absorbed by 5 percent of sodium hydroxide. After the reaction is finished, slowly adding the reactant into 600g of ice water under stirring for dilution, adding 30% of sodium hydroxide for neutralization after uniform dilution, adjusting the pH to be 7-8, and concentrating to remove water to obtain 165g of terpineol-based sodium sulfate, wherein the product is a white crystal.
Example 2:
formula 1 of the water-based soft metal cleaning agent: APG 081010 parts, sodium ethylene diamine tetra-methyl phosphate 2 parts, potassium hydroxide 3 parts, potassium silicate 3 parts, terpineol-based sulfate (sodium terpineol sulfate obtained in example 1) 2 parts, and ultrapure water 100 parts by weight.
Example 3:
water-based soft metal cleaner formula 2: according to the mass ratio, APG 081015 parts, 3 parts of sodium hydroxydiphosphate, 5 parts of sodium hydroxide, 4 parts of sodium silicate, 3 parts of terpineol alcohol-based sulfate and 100 parts of ultrapure water.
Example 4:
water-based soft metal cleaner formula 3: according to the mass ratio, APG 08107 parts, 1 part of tetra sodium salt, 3 parts of sodium hydroxide, 3 parts of sodium silicate, 2 parts of terpineol alcohol-based sulfate and 100 parts of ultrapure water.
Example 5:
the stain removal capability of the aluminum test piece and the copper test piece is tested according to national light industry standard QB/T2117-1995 universal water-based metal detergent, and the test results of the cleaning capability are shown in the following table 1:
table 1:
| formulation of | Formulation 1 | Formulation 2 | Formulation 3 |
| Aluminum test piece | 96.8％ | 97.2％ | 92.7％ |
| Copper test piece | 95.0％ | 95.3％ | 91.8％ |
For test pieces of the same material, the difference between the detergency of formula 1 and that of formula 2 is very small, but formula 2 uses more surfactant, and the formula 1 is determined as the preferable formula from the aspects of economy and detergency.
In addition, APG0814 and APG1214 can be selected as the alkali-resistant APG, and because the surface activities of different surfactants are different, the optimal mixture ratio of the cleaning agent containing different surfactants is also different, and the optimal mixture ratio can be obtained through experiments.
