Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to apply organic fluorine, organic silicon, organic fluorine silicon and other protective agents on the back of the stone for the most commonly used anti-alkali solution for stone. However, these protection methods will cause cement to infiltrate and the stone will lose its anchorage. effect, leading to the defect that the bonding strength of the back of the stone decreases, and a stone anti-alkali back coating material and a preparation method thereof are provided

example 1

[0025] Weigh 200g of hydroxyapatite into a gauze bag, tie the mouth of the bag tightly, immerse the gauze bag into the bottom of the biogas slurry in the biogas tank, and let it soak for 3 days. After soaking, take out the gauze bag and pour out the hydroxyapatite. And immediately spray and freeze with liquid nitrogen for 2 minutes, put the frozen hydroxyapatite into a jet mill for 20 minutes and pass through a 200-mesh sieve, collect the sieved material to obtain porous hydroxyapatite powder; put the above-mentioned porous hydroxyapatite Stone powder, sodium silicate solution with a mass fraction of 40% and silane coupling agent KH550 are mixed according to a mass ratio of 10:50:1 and poured into an ultrasonic oscillator, and ultrasonically oscillated at a power of 100W and a frequency of 30kHz. 1h, after the ultrasonic treatment, filter and separate to obtain the filter residue; mix the obtained filter residue and plant essential oil in an equal mass ratio to obtain a mixture...

Abstract

The invention relates to the technology of stone protection, particularly relates to a stone alkali- resistant back-coating material, and also relates to a preparation method of the stone alkali- resistant back-coating material. The preparation method comprises the following steps: firstly, enabling mixed emulsion to permeate into stone pores and form a layer of solid polarization film, wherein the film is extremly low in surface tension, thus water with high surface tension cannot wet and permeate into the polarization film, and water and alkali prevention aims are achieved; secondly, using modified powder, treating by a sodium silicate solution and a silane coupling agent, and modifying by plant essential oil under microbial action, thus providing space for cement permeation by using a porous powder layer, being capable of making dehydration condensation reaction by silicon hydroxyl on the surface of powder and silicon hydroxyl on the surface of concrete, so as to form an Si-O-Si bond with great bond energy. The bond energy is improved, so that bonding strength between the powder layer and the cement is also improved, the problems that the cement difficultly permeates into the stone, and an anchoring effect is lost, so that the bonding strength of the back of the stone is lowered is solved, and the application prospect is wide.

Description

technical field [0001] The invention relates to stone protection technology, in particular to a stone anti-alkali back coating material, and also relates to a preparation method of the stone anti-alkali back coating material. Background technique [0002] Natural stone has always occupied a very important position in the field of building decoration materials because of its high-grade, elegant and magnificent decorative effects. Various problems, such as pan-alkali and whitening in places with high humidity, cracking and warping when the floor is laid, etc. The reason for the above phenomenon is mainly because there are large pores on the back of the natural stone, and the natural stone itself is different from the laying. The performance of the surface is different; the most commonly used solution at present is to apply organic fluorine, organic silicon, organic fluorine silicon and other protective agents on the back of the stone. These protective agents penetrate into the...
