Abstract
A concrete mold release agent is produced by chemical technology by using stearic acid as a main raw material. When the concrete mold release agent is sprayed and brushed on a concrete template and dried, a layer of a hydrophobic film is formed; the concrete mold release agent has the advantages of easy demolding and low cost, and the concrete product has a flat and smooth surface, and marble texture.
Description
Affiliated technical field
The present invention is a kind of concrete is isolated concrete product and template in construction process a releasing agent, has the easy demoulding, and the cement products surfacing has marble gloss, and is with low cost.
Background technology
At present, well-known releasing agent roughly has: the used oil class, and saponin, plant oil, the wax oil class, surfactant-based, template lacquer class.Above releasing agent respectively has advantage, but also exists the defective of itself:
1. used oil class: cheap advantage is arranged, but greasy dirt is prone to pollute workmen's clothing and lubricious, the template after the brushing is difficult for carrying, causes the accident easily, and after the demoulding, the cement products surface irregularity has the black greasy dirt, is difficult for the demoulding;
2. saponin: cheap advantage is arranged, but after such releasing agent fermentation, give out unpleasant stink, the construction environment of locality has been brought pollution, and be difficult for the demoulding, the cement products surface irregularity;
3. plant oil: the advantage that has raw material to be easy to get, but such is to be vegetables oil fully, has directly influenced the effect that thes cement solidifies; Inequality is solidified with the not solidified finished ground cement of one deck in the cement products surface, has caused the cement products surface color deep mixed; Uneven, cost is higher;
4. wax oil class: the advantage of the easy demoulding is arranged, but such is through the emulsifying agent emulsive, contains organic volatile property organic solvents such as formaldehyde in the emulsifying agent, and human respiratory, vision system are had infringement, higher cost has caused and has been difficult to the reason that big area is promoted the use of;
5. surfactant-based: cheap advantage is arranged, but its stripping result is limited, often causes the phenomenon of template adhesion, cement products surface finish disappearance is serious, need carry out secondary and whitewash operation;
6. template is coated with lacquer class: there is stripping result good, and the advantage of smooth surface such as mirror, but it contains organic volatile property solvents such as YLENE; Harmful; The paint film that remains in template surface is easy-clear not, the most important thing is high cost, has limited the use range of template lacquer; At present, be mainly used in the part model workshop section of priority projects such as high ferro.
Releasing agent through above kind compares, and sum up to draw a conclusion: price is high, and stripping result is good, the cement products of deviating to improve grade; Price is low, is not that stripping result is bad, influences the outward appearance of cement products exactly.
Summary of the invention
Through learning from other's strong points to offset one's weaknesses, this releasing agent has been invented in research and development for many years; The present invention is not only cheap, and stripping result is good, the cement products smooth surface; Marble texture is arranged, guaranteed the class of cement products, improved construction quality and efficient; Has not corrosion Sheet Steel Form, the advantage of maintenance wooden form.
The technical formula that the present invention taked is:
(mass parts %)
Triple Pressed Stearic Acid 3.0-10.0
Soda ash 0.1-0.5
Pottasium Hydroxide 0.5-2.0
Sodium Nitrite 1.5-5.0
Water 93.5-80.5
Sodium Benzoate 1.0-2.0
Production process of the present invention is:
1. take by weighing the quantity of material in the above prescription;
2. melt for use at the container internal heating Triple Pressed Stearic Acid;
With water when alkaline-resisting container is heated to 60 ℃-70 ℃, add soda ash successively while stirring, Pottasium Hydroxide, the Triple Pressed Stearic Acid of thawing, the insulation
4. reacted 1 hour, and be cooled to about 30 ℃, add Sodium Benzoate, Sodium Nitrite;
5. filter packing and be finished product.
6. the present invention only needs spray (being coated with brush) on template in use, after 1 hour drying, forms one deck hydrophobic film, can carry out Concrete Construction.
Claims (2)
1. concrete parting agent, by Triple Pressed Stearic Acid, Pottasium Hydroxide, Sodium Nitrite; Soda ash, Sodium Benzoate, water is formed, and its prescription is: Triple Pressed Stearic Acid 3.0-10.0; Pottasium Hydroxide 0.5-2.0, Sodium Nitrite 1.5-5.0, soda ash 0.1-0.5, Sodium Benzoate 1.0-2.0; Water 93.5-80.5, the prescription by mass parts produces through the chemical industry operation.
2. a concrete parting agent is characterized in that: be used for brushing shotcrete template, be prone to the demoulding, the protection template.
