2O, rank is preferably the technical grade rubber powder can adopt different fineness according to actual needs.The consumption of water is according to different mobility and requirement of strength, and " water " is for meeting the clean water of " JGJ63-2006 the reinforcement of concrete water quality standard ".Can also be mixed with high-alumina cement in gelling mixture, high-alumina cement is 10 parts ~ 20 parts.
Based on the preparation method of the fast repairing material of damaged stone material in building, the first step is made magnesium phosphate cement, and magnesium phosphate cement is made by phosphoric acid salt, magnesia powder and the large component of borax three, and this three large component is arranged in pairs or groups with certain proportion; Second step mixes magnesium phosphate cement, sand, silicon sol making gelling mixture, and establishing the gelling mixture quality is 100 parts, and magnesium phosphate cement is 40-55 part, and sand is 40-50 part, and silicon sol is 10-15 part.Magnesium phosphate cement, sand, silicon sol can be mixed by dry powder blender.
As a kind of preferred version, contain phosphoric acid salt, magnesia powder and borax in magnesium phosphate cement.With phosphoric acid salt and borax use respectively the drying facility drying treatment to phosphoric acid salt temperature and borax temperature higher than above 10-20 ℃ of local top temperature in summer; The phosphoric acid salt that drying treatment is crossed and borax are crossed respectively the standard square hole sieve, screen out more slightly, harder particle; With the borax processing superphosphate, processed and magnesium oxide in mass ratio 30-40:10-20:40-50 coordinate, make magnesium phosphate cement.
Phosphoric acid salt is preferably potassium primary phosphate.In magnesium phosphate cement, potassium primary phosphate is preferably technical grade, and purity is 99.8%; Magnesium oxide purity is preferably 85%.At first, potassium primary phosphate and borax are used respectively drying facility drying treatment 12h, temperature is 50 ℃; Potassium primary phosphate and borax that drying is crossed are crossed respectively 150 μ m square hole sieves, guarantee that screen over-size is no more than 10%; The potassium primary phosphate of processing and borax are deposited separately under the condition of sealing, drying, and each component coordinates by suitable proportion can be prepared into magnesium phosphate cement.
Borax is preferably and is that technical grade, purity are 95%.Borax is the retardant commonly used of magnesium phosphate cement, the B that the borax dissolving generates

2O。Along with the carrying out of reaction, product is crystallization gradually.
Because magnesium oxide in system is superfluous, the product of separating out just covers mgo surface, forms one deck hydrated product film magnesia particle is closely connected to one.Along with the continuation of reaction, the K+ in solution and PO
4 3-Progressively see through the hydrated product membrane permeation to the MgO particle surface, form more hydrated product, crystallization produces volumetric expansion and causes the hydrated product film rupture.MgO is exposed to again in acidic solution, and hydration reaction speed is accelerated again, generates a large amount of hydrated products.Along with being on the increase of hydrate, contact and adhesion make the magnesium phosphate cement slurry become a crystalline texture net take the MgO particle as framework, take the phosphoric acid salt hydrate as the main binding material each other, thereby make magnesium phosphate cement be hardened to the very hardenite of strong mechanical performance.
The concrete formula of this product and using method depend on the disease form of waiting to repair the zone, the repairing of some stone material may be aided with rarer slurry slip casing by pressure or expand seam grouting, and the repairing of some stone material only needs with thicker mixture employing level or vertically subsidize to get final product.Following embodiment further illustrates of the present invention, rather than limits the scope of the invention.All solids material summation is 100 mass parts, and liquid material such as silicon sol and water measure take 100 mass parts as radix.
