Embodiment 1

[0029] The raw materials in the examples of the present invention are all commercially available raw materials.

[0030] An environmentally friendly water-based dewaxing agent, the composition of which is (taking 1000g of water-based dewaxing agent as an example):

[0031] Potassium pyrophosphate: ratio 30g;

[0032] EDTA-4Na: Proportion 20g;

[0033] Sodium Metasilicate Pentahydrate: Proportion 5g

[0034] The total alkali content of sodium metasilicate pentahydrate (calculated as Na2O) is 28.5-30.5%;

[0035] TX-10: Proportion 70g;

[0036] FMEE: Proportion 70g;

Abstract

The invention relates to an environmental protection water base dewaxing agent and a preparation method thereof. The environmental protection water base dewaxing agent comprises, by weight, 1-5% of phosphate, 1-4% of complexing agent, 0-3% of sodium metasilicate, 10-20% of surface active agent, 5-20% of solvent and balanced distilled water. The main preparation steps are firstly adding distilled water, sequentially adding the phosphate, the complexing agent and the sodium metasilicate under stirring condition for stirring 20-30min, adding the surface active agent to continuously stir for 20-30min, and finally adding the solvent to stir until materials are completely dissolved. The environmental protection water base dewaxing agent can completely replace a chloro solvent dewaxing agent which is poisonous and harmful to the environment. The environmental protection water base dewaxing agent is simple and scientific in mechanism of action, achieves functions of stripping, emulsification,wax dissolving, greasy dirt dissolving and metallic oxide through reasonable compounding of the surface active agent, the solvent, the alkalinity assistant, the complexing agent and the like, is safein use, environment-friendly, non-toxic, high in dewaxing efficiency, applicable to materials of optical glass, stainless steel, aluminum and the like, free of corrosion on washed objects and free ofresidues after washing, and is an ideal substitute of the chloro solvent.

Description

technical field [0001] The invention belongs to the field of chemical cleaning agents, and relates to a dewaxing agent, in particular to an environment-friendly water-based dewaxing agent and a preparation method thereof. Background technique [0002] In the field of optical glass processing and manufacturing, in order to avoid damage to the optical lens during processing, a layer of wax film is often applied to its surface, and it is also cleaned and dewaxed before leaving the factory. In the watch, handicraft, jewelry and other industries, the finished workpiece needs to be polished, and the polished workpiece also has polishing wax attached, which needs to be thoroughly cleaned before leaving the factory. The above-mentioned wax scale is mainly composed of paraffin, fatty acid, rosin soap, metal oxides and some inorganic solid polished small particles, while the traditional dewaxing agent is a chlorinated hydrocarbon solvent such as trichloroethylene. Although the dewaxi...
