It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The invention discloses a novel crystal hardening agent, which comprises the following raw materials in parts by weight: 0.5 to 3.0 percent of low molecular weight organic dicarboxylic acid, 5 to 10 percent of high boiling point organic solvent, 15 to 25 percent of organic silicon polymer, 15 to 25 percent of inorganic silicate and 0.5 to 2.5 percent of SiO₂Micro crystal powder and 0.5-2.5% of nano composite zirconium oxide ZrO₂Micro powder, 0.5-2.5% of nano composite zirconium oxide ZrO₂Micro powder and 32-63.5% of water. The novel crystal hard agent can be applied to the stone surfaces of floors and walls to ensure that the stone surfaces are bright, and can also increase the hardness of the stone surfaces to protect the stone, prolong the service life of the stone and the like, wherein the stone is marble, terrazzo or certain granite and the like.

Preferably, the low molecular weight organic dicarboxylic acid is one or more selected from organic dicarboxylic acids containing 4-10 carbon atoms, such as one or more selected from succinic acid, adipic acid, glutaric acid, pimelic acid, suberic acid, azelaic acid and sebacic acid. In the invention, the dicarboxylic acid is used for accelerating calcium ionization in the stone, and promoting calcium ions in the stone to react with inorganic silicic acid ions more fully to form crystal faces.

Preferably, the high boiling point organic solvent is selected from one or more of organic polyols, such as ethylene glycol, pentanediol. The organic polyol can coordinate and control the evaporation speed of each component of the crystal hard agent, is used for improving the efficiency of the whole polishing process, and enables the surface of the treated stone to achieve the effects of drying and brightening in a short time. In addition, since the alcohol compound itself has a hydroxyl bond in the composition, the hydrophobic compound and the water-soluble compound can be dissolved, and therefore, the alcohol compound has good solvent compatibility. And the alcoholic compound can keep the leveling property of the treatment agent product of the invention after being coated on the surface of the marble.

When the organic silicon polymer is combined with the stone, a layer of uniform and compact organic silicon film can be formed on the inner wall of capillary pores on the surface of the stone. Under certain conditions, silicon hydroxyl on the surface of the stone and silicon hydroxyl in the organic silicon film are subjected to condensation reaction to form chemical bonds, so that the organic silicon film is firmly attached to the surface of the stone. The organic silicon film is in a directional arrangement structure on the surface of the stone, the Si-O bond of the organic silicon film is tightly close to the surface of the stone, and the alkyl extends outwards. Since the alkyl group is a hydrophobic group, the oriented silicone film has a strong hydrophobic property. After the organic silicon material is coated on the surface of the stone, the contact angle between the surface of the stone and water drops can be increased to 103 degrees; secondly, the bond energy of Si-O bond is high, and the organosilicon hydrophobic film has excellent weather resistance, so the waterproof effect is durable.

The inorganic silicate may be optionally selected from one of sodium lithium silicate, potassium lithium silicate, magnesium lithium silicate, calcium lithium silicate, zinc lithium silicate and chromium lithium silicate.

Generally, lithium silicate and other components of the crystal hard agent permeate into the surface of the stone to be treated, and the lithium silicate reacts with calcium-containing components in the stone to form a compact intermediate layer between a coating on the surface of the stone and the surface of the stone, so that the hardness of the surface of the stone is enhanced, the mechanical properties of the stone can be improved, and evaporation of water molecules inside the stone and inward permeation of external water are prevented, thereby solving the problem of water seepage prevention in the treatment of the surface of the stone. Especially for marble with poor acid resistance, the treated marble has enhanced acid resistance.
