Abstract
A disclosed chemical polishing solution for pure aluminium and aluminium alloy castings is characterized by being prepared from the following raw materials in parts by weight: 2-4 parts of potassium chloride, 3-4 parts of calcium carbonate, 3-5 parts of ethene diamine, 1-2 parts of urotropine, 5-6 parts of PPG-n castorate, 3.5-4.5 parts of lithium-based grease, 2-4 parts of citric acid, 3-5 parts of rosin amine, 1-2 parts of methylated methylol urea, 6-8 parts of phosphoric acid, 5-7 parts of an auxiliary agent, and 300 parts of deionized water. The chemical polishing solution is reasonable in formula, comprises phosphoric acid, citric acid and other conventional compositions, and also integrates calcium carbonate abrasive, lithium-based grease, PPG-n castorate and other surfactants and auxiliary agents and the like through a grinding technology, has good lubricity and uniformly-dispersed abrasive, and forms a protective membrane on a metal surface after being processed, and the membrane has the characteristics of being capable of preventing air corrosion and convenient to clean. The chemical polishing solution is stable and uniform in quality, good in polishing performance, stable in polishing speed and suitable for polishing of aluminium and aluminium alloy.
Description
Technical field
The present invention relates to technical field of surface, particularly chemical brightening solution of a kind of fine aluminium and aluminum alloy casting and preparation method thereof.
Background technology
The method application of aluminium and aluminium alloying optical polishing is more extensive, but the maximum shortcoming existing is because polishing fluid temperature is high, reaction is fast, while production on automation line, a station is long to next station required time, cause workpiece from chemical polishing bath out, carry a large amount of residual chemical rightenning liquid medicine and rest on aerial, in dirty, the low process of raffinate simultaneously due to air exist effects on surface to produce excessive erosion, oxidation to form the shortcomings such as heterochromatic, abrasive material damage workpiece on surface, thereby affected product quality.The present invention i.e. the technological improvement to this mixed polishing solution; find by abrasive lapping is crossed with tensio-active agent and mixed; not only can play the effect of lubricated abrasive material; and can form layer protecting film at metal finished surface; prevent that top layer is by air corrosion; and adopt water base making, and the amount of heat producing in the time of medal polish, cooling is respond well.
Summary of the invention
The object of this invention is to provide chemical brightening solution of a kind of fine aluminium and aluminum alloy casting and preparation method thereof.
In order to realize object of the present invention, the present invention passes through following scheme implementation:
A chemical brightening solution for fine aluminium and aluminum alloy casting, is made up of the raw material of following weight part: Repone K 2-4, calcium carbonate 3-4, quadrol 3-5, urotropine 1-2, ricinolic acid polyoxypropylene ester 5-6, lithium soap grease 3.5-4.5, citric acid 2-4, rosin Amine D 3-5, methyl-etherified methylolurea 1-2, phosphoric acid 6-8, auxiliary agent 5-7, deionized water 300;
Described auxiliary agent is made up of the raw material of following weight part: aluminium sesquioxide 4-6, nano titanium oxide 5-7, water glass 1-2,1-Methoxy-2-propyl acetate 3-4, Lauryl Alcohol ester 2-3, methyl acrylate 2-4, croscarmellose sodium 2-3, emulsifier BP 4-5, water 50-54; First preparation method adds aluminium sesquioxide, nano titanium oxide, croscarmellose sodium, emulsifier BP in the water of half amount, grind 1-2 hour, then slowly add all the other remaining components, slowly be heated to 70 DEG C-80 DEG C, stirring reaction 30-50 minute under 300-500 rev/min of condition, is cooled to room temperature and get final product.
The chemical brightening solution of a kind of fine aluminium of the present invention and aluminum alloy casting, made by following concrete steps:
(1) calcium carbonate, ricinolic acid polyoxypropylene ester are mixed, add appropriate deionized water, be heated to 35 DEG C-40 DEG C, grind 35-40 minute, obtain mixing A material;
(2) all the other remaining components except auxiliary agent are joined in reactor, be uniformly mixed, be slowly heated to 35 DEG C-45 DEG C, insulation 1-1.5 hour, obtains mixing B material;
(3) the mixing B material of insulation is slowly joined while stirring and mixed in A material, after fully stirring, add auxiliary agent, continue to stir 20-35 minute, be cooled to room temperature and get final product.
Excellent effect of the present invention is: the present invention fills a prescription rationally, not only contain traditional composition such as phosphoric acid, citric acid, more by grinding technics by combinations such as tensio-active agent, auxiliary agent such as calcium carbonate abrasive material, lithium soap grease, ricinolic acid polyoxypropylene esters, not only there is good oilness, abrasive material is uniformly dispersed, and processing is later at metallic surface formation layer protecting film, has and prevents air corrosion and be convenient to the characteristic of cleaning; Steady quality homogeneous of the present invention, polishing performance is good, and polishing speed is stable, is applicable to aluminium and aluminium alloy polishing.
