Abstract
本发明公开了一种菱镁胶凝材料减水抗返卤改性剂的制备方法，采用水、苯酚、苯磺酸钠、工业甲醛、有机硅防水剂为原料，其特征在于各原料在总重量中的重量百分比分别为：水18-22%、苯酚10-14%、苯磺酸钠6-10%、工业甲醛8-12%、有机硅防水剂45-55%。将其加入菱镁水泥中，具有可有效的提高其制品的抗吸潮返卤而又提高强度的特点。The invention discloses a preparation method of a water-reducing and anti-halogenation modifier for magnesite gelling materials, which uses water, phenol, sodium benzenesulfonate, industrial formaldehyde and organic silicon waterproofing The weight percentages in the weight are respectively: 18-22% of water, 10-14% of phenol, 6-10% of sodium benzenesulfonate, 8-12% of industrial formaldehyde, and 45-55% of organic silicon waterproofing agent. Adding it to magnesite cement has the characteristics of effectively improving the resistance to moisture absorption and return to halogen of its products and improving the strength.
Description
Technical field
The present invention relates to a kind of magnesite binding material properties-correcting agent, especially a kind of preparation method of water-reducing and surface halide accumulation resisting modifier for magnesite binding material.
Background technology
Magnesite binding material claims magnesia cement again, it is a kind of air hardening cementitious materials, when manufacturing a product with this material, having with it does not need moist maintenance, gain in strength fast, anti-folding, ultimate compression strength height, weakly alkaline, low-corrosiveness, elasticity height, good toughness, in light weight, organic and inorganic materials or fiber are had preferably characteristics such as tackiness, be widely used in the fields such as building, decoration, urban construction, agricultural.But because this material product has easily damp suction surface halide accumulation of surface, and even more serious under hot and humid condition, seriously influenced the use properties of goods.In order to overcome this defective, people have carried out a large amount of tests, and the employing Adlerika that has replaces the technical scheme of magnesium chloride solution, though this scheme can overcome above-mentioned defective, the intensity of goods reduces bigger, still can not obtain the ideal effect; The technical scheme that also has employing to place water to soak in the goods of firm demoulding is so that with Cl
-Separate out, this technical scheme still has the defective that reduces product strength.
Summary of the invention
Task of the present invention is to provide a kind of preparation method that can effectively improve the anti-damp suction surface halide accumulation of magnesite binding material goods and improve the water-reducing and surface halide accumulation resisting properties-correcting agent of its intensity for overcoming the defective that exists in the above-mentioned prior art.
For realizing above-mentioned task, the present invention adopts following technical scheme: adopting water, phenol, benzene sulfonic acid sodium salt, industrial formol, waterproofing agent of organosilicon is raw material.Each raw material shared weight percent in gross weight is respectively:
Water 18-22%
Phenol 10-14%
Benzene sulfonic acid sodium salt 6-10%
Industrial formol 8-12%
Waterproofing agent of organosilicon 45-55%
Above-mentioned raw materials is water-reducing and surface halide accumulation resisting modifier for magnesite binding material of the present invention by taking out tinning in its per-cent metering back adding reactor after stirring 150-200 minute under the 80-90 ℃ of humidity condition.
Because the composition of magnesia cement is to be calcining and the magnesia after Raymond mill is levigate under 800-850 ℃ the condition in temperature by wagnerite, proportion is 1.22-1.24g/cm
3Magnesium chloride solution and organic plant fiber such as inert material such as Paris white, talcum powder, calcite in powder, sand and powdered rice hulls, saw powder.After water-reducing and surface halide accumulation resisting properties-correcting agent of the present invention joins in the magnesia cement slip, will form very thin hydrophobic membrane, expose simultaneously at outside surface and also form hydrophobic membrane at the pore surface of magnesia cement inside and kapillary internal surface.As this film and airborne CO
2Form the stronger and competent especially carbonized film of hydrophobic nature after the gas effect, can make MgCl like this because of free state
2Exist the surface that causes former magnesia cement to have the intensive moisture absorption to become the very strong surface of hydrophobic nature, be actually free MgCl
2Screen shuts, and makes it lose the chance that absorbs moisture in the air dielectric.In addition,, can reduce the bittern consumption in the agglutinate like this, reduce free MgCl owing to have stronger diminishing function in the properties-correcting agent that mixes
2Amount.After adding properties-correcting agent, the total consumption of bittern can reduce 10-15%, promptly free MgCl
2Reduce 3-4%, reduced the possibility of goods damp suction surface halide accumulations; Be because water consumption reduces again, correspondingly reduced capillary channel, this has also improved the water tolerance of goods simultaneously.
In sum, can effectively realize task of the present invention.
