Interface reinforcer preparation method and application of interface reinforcer
The present invention discloses an interface reinforcer preparation method and application of the interface reinforcer. The preparation method comprises the following steps: firstly, reheated magnesium oxide, phosphate and a borax retarder are prepared into dry powder, wherein the preheating magnesium oxide and the phosphate are in a mass ratio of (0-4):1, and the borax retarder accounts for 3-12% of the reheated magnesium oxide in mass; coal ash powder which accounts for 0-20% of the dry powder in mass is doped for preparation and uniform agitation; then water 9-25% of all the raw materials in mass is added and quickly agitated for 3-5 min so as to obtain the interface reinforcer. The interface loosening part of an old substrate is cleaned and kept dry and dust is cleared in specific application; the interface reinforcer is uniformly coated or sprayed on the interface of the old substrate till the whole interface is soaked; finally, magnesium phosphate cement concrete is poured and tightly pounded before the interface reinforcer is coagulated and dried. The method achieves remarkable improvement on the adhesion performance of the magnesium phosphate cement concrete through the preparation and use of the interface reinforcer, the material cost is remarkably lowered, and the method has a good market prospect.
