Description
Technical field
The invention discloses a kind of special foam cleaning agents in metal surface, belong to metal cleaner technical field.
Background technology
After metal works processing, surface can carry dirt, such as various cutting fluids, rail oil, lapping liquid, dust, hand perspiration,
If not cleaning up, being smoothed out, and can cause and accelerate corrosion for manufacturing procedure is not only influenced, influences product
Processing quality and service life.In addition, it in spray painting, applies before glaze, the finishing such as plating and the repair and maintenance of mechanical equipment
In, all it be unable to do without cleaning process.The selection of cleaning and the quality of cleaning performance, are directed not only to the energy, safety and environmental protection etc.
Significant problem, and directly influence the performance and quality of product, so have become can not in modern industrial production for cleaning process
The important link lacked.Metal cleaner is generally divided into two kinds of aqua type and solvent type.Water base metal cleaning agent had with water generation
Oil saves the energy, does not endanger operator's health, pollution is few, environmental-friendly, easy firing（Safety）It is at low cost etc. a series of with cleaning
Superiority is rapidly developed nearly ten years in China, but generally existing cleans the skills such as rate, defoaming, rust-preventing characteristic and stability
Art performance indicator cannot meet the shortcomings that industrial production needs.
At present, common metal cleaner divides solvent type, half solvent type and aqua type.In solvent type metal cleaner, stone
Oil solvent is inflammable, explosive and waste of resource.Chlorofluorocarbons is most common solvent type metal cleaner, but since it is smelly to air
The destruction of oxygen layer and it is disabled.Thus, solvent type metal cleaner is just gradually by half solvent type and aqua type metal cleaner institute
It substitutes.Relative to half solvent type, the application advantage of aqua type metal cleaner is more prominent.But aqua type metal cleaner is in work
It is also insufficient below generally existing in industry high-pressure wash：Foam is more, is unfavorable for cleaning；Mostly all containing nitrite, phosphate,
The ingredient harmful to human body and environment such as silicate；Greasy dirt into washing lotion is emulsified dispersion after being cleaned, and is not easy to detach, make
Into the wasting of resources.Therefore, it also needs further to study it.
Invention content
The present invention solves the technical problem of：It is asked for conventional metals foam cleaning agent clean effect is bad
Topic, provides a kind of special foam cleaning agent in metal surface.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of special foam cleaning agent in metal surface, is made of the raw material of following parts by weight：20~30 surfactants, 8
~10 parts of modified cladding activated carbons, 8~10 parts of starch, 8~10 parts of sodium citrates, 8~10 parts of phosphatide, 20~30 parts of tealeaves concentrations
Liquid, 10~20 parts of anhydrous sodium metasilicates, 60~80 parts of water, 20~30 parts of chitosan liquid, 5~6 parts of builders；
The preparation process of the special foam cleaning agent in metal surface is：Following raw material is weighed by raw material composition, by surface-active
Agent, modified cladding activated carbon, starch, sodium citrate, phosphatide, tealeaves concentrate, anhydrous sodium metasilicate, water and help chitosan liquid
Lotion is stirred to get the special foam cleaning agent in metal surface.
It is lauryl sodium sulfate that the surfactant, which is surfactant, fatty alcohol polyoxyethylene ether, alkyl glycosides,
One kind in cocoyl glucoside, lauryl glucoside or cetearyl glucoside.
The preparation process of the modified cladding activated carbon is：Activated carbon and calcium hydroxide saturated solution are stirred, to
Carbon dioxide is passed through in calcium hydroxide saturated solution, is filtered, nitrogen charging insulation reaction coats activated carbon to get modified；The hydrogen-oxygen
It is the calcium hydroxide saturated solution that temperature is 20~22 DEG C to change calcium saturated solution.
The phosphatide is soybean lecithin, any one in milk phosphatide or yolk phospholipid.
The preparation process of the tealeaves concentrate is：By tealeaves and water in mass ratio 1：30~1：50 heating stirrings mix,
Filtering, is concentrated under reduced pressure to get tealeaves concentrate；The tealeaves is Biluochun tea, any one in Longjing tea or extra-strong tea.
The preparation process of the chitosan liquid is：By chitosan and water in mass ratio 1：50~1：After 100 mixing swellings, add
Thermal agitation is dissolved to get chitosan liquid.
The builder is sodium carbonate, sodium metasilicate, and sodium tripolyphosphate is arbitrary in sodium carboxymethylcellulose or sodium citrate
It is a kind of.
The beneficial effects of the invention are as follows：
（1）The present invention is first, molten by activated carbon and calcium hydroxide saturation by adding modified cladding activated carbon and tealeaves concentrate
Liquid mixes, then is passed through carbon dioxide so that calcium hydroxide reacts with carbon dioxide, generates calcium carbonate, the calcium carbonate of generation
Again through nitrogen charging insulation reaction, calcium carbonate generates calcium oxide under the high temperature conditions, and in preparation process, calcium oxide reacts generation with water
Calcium hydroxide, the calcium hydroxide and oil response of generation, effectively removes greasy dirt, modified after surface calcium hydroxide reacts completely
Internal unreacted calcium carbonate is exposed in cladding activated carbon, and calcium carbonate can occur acute with the active ingredient in tealeaves concentrate
Strong reaction, generates a large amount of gas and heat, and gas further enhances detergency ability in cleaning agent；
（2）The present invention is by adding phosphatide and chitosan liquid, first, good emulsification, enhancing cleaning is played in system
The detergency ability of agent, secondly, phosphatide is negatively charged so that the binding force of chitosan and phosphatide enhances, and negative electrical charge phospholipid composition accounts for
According to the position of the part functional group in chitosan skeleton, the oscillation intensity of covalent bond in chitosan molecule is reduced, meanwhile, film
In the free hydroxyl of hydrophilic bond can be formed with water roll into a ball and reduce, the water content of film reduces, so that the mechanical performance of protective film
It gets a promotion, further enhances protective effect of the protective film to metal, extend the service life of metal, in addition, phosphatide is with negative
Charge can be adsorbed on metal surface and form metal layer, has good oil rub resistance and antioxygenic property.
