Description

Prescription of low-carbon environment-friendly wax pattern cleaning agent and preparation method thereof

One, technical field:

The present invention relates to the chemical cleaning technique field, particularly prescription of a kind of low-carbon environment-friendly wax pattern cleaning agent and preparation method thereof.

Two, background technology:

It is the critical process of solvent casting process for making shell that wax-pattern cleans, and its cleaning performance directly influences the hanging quality of formwork, finally has influence on the final product quality of foundry goods.The early stage general employing of wax-pattern cleaning ketone, aromatic hydrocarbons etc. have very strong volatile solvent and directly clean, and consumption is big, toxicity is big, cost is high, and is inflammable, explosive, seriously polluted.The water base cleaning agent of wax mould that last century, the nineties was developed does not fire, not quick-fried, and toxicity is less relatively, progressively replaces the technology that solvent directly cleans.Because this clean-out system contains ODS material and other objectionable impurities of destroying atmospheric ozone layer, belongs to the product that Montreal protocol is eliminated.Minority does not contain the water base cleaning agent of wax mould of ODS material, need be heated to the greasy dirt that could remove the wax-pattern surface about 40 ℃ when cleaning, and exist scavenging period long, shortcomings such as wash degree is low, energy consumption height.

Three, summary of the invention:

Purpose of the present invention is exactly the above-mentioned defective that exists at existing cleaning agent of wax mould, and providing a kind of does not have harm to atmospheric environment and operator, prescription of the novel low carbon environment-friendly wax pattern cleaning agent that the normal temperature cleaning speed is fast, consumption is few, energy consumption is low and preparation method thereof.

Its technical scheme is:

One-tenth by following weight part is grouped into: propylene glycol monomethyl ether 20～120g, butanone 20～120g, hexanaphthene 20～120g, nonylphenol polyethylene ether 1～100g, alkyl benzene sulphonate (ABS) 1～100g, trolamine 1～100g, fat alcohol polyethylene ether 1～100g, tap water 400～700g, total amount is 1000g altogether.

The preparation method:

With 1: 1～2: 0.8～1.2 pure component mixed, the pure component consumption of described mixed solvent is 10～60 parts to the first step with propylene glycol monomethyl ether, butanone, hexanaphthene;

The water of second step with 0.1～10 part of nonylphenol polyethylene ether, 0.1～10 part of alkyl benzene sulphonate (ABS), 0.1～10 part of fat alcohol polyethylene ether and 2～10 parts fully stirs evenly in the mixing solutions that joins the first step gained;

The 3rd step added 0.1～10 part trolamine under the stirring velocity of 200～250rpm, and supplied institute's water requirement, and the gross weight that makes whole materials is 100 parts;

The emulsification under the rotating speed of 200～3000rpm of the 4th step made white milk sap in 1～2 hour and promptly gets this patent product.

The invention has the beneficial effects as follows:

1. clean-out system of the present invention does not contain the ODS material;

2. clean-out system of the present invention is a kind of oil-in-water molecular structure, and solvent does not directly contact with air, and volatile quantity is few;

3. clean-out system of the present invention adopts normal temperature dipping to clean, and consumption is few, and cleaning speed is fast, do not heat, and the wash degree height, the hanging quality is good;

4. clean-out system production technique of the present invention is simple, and normal temperature and pressure is easy to operate, easily control;

5. clean-out system raw material sources of the present invention are extensive, less investment, and cost is low, and market potential is big;

6. the residue that clean-out system of the present invention cleans behind the wax-pattern is few, and the tolerance of dimension and the surface quality of foundry goods are controlled easily;

7. when clean-out system of the present invention cleans human body skin is not had the burn into nontoxicity, the tensio-active agent of use is easily by biological degradation, and is pollution-free to ambient air;
