Embodiment 1

[0022] Mixture solution of trialkoxysilane and tetraalkoxysilane 45%

[0023] 1% Fluorosilane [CF 3 (CF 2 ) 5 CH 2 CH 2 Si(OC 2 h 5 ) 3 】solution 45%

[0024] 30% nano silicon oxide solution 3.0%

[0025]10% nano-titanium oxide solution 7.0%

[0026] Wherein the mixture solution of trialkoxysilane and tetraalkoxysilane is prepared: first dissolve 40 parts by mass of tetramethoxysilane with 4 times parts by mass of 0.4% acetic acid aqueous solution, adjust the average molecular weight between 300 and 700, and then Add 100 parts by mass of ethyltriethoxysilane to 150 parts by mass of isopropanol to dissolve, then mix the two solutions, stir evenly and heat at 50°C for 60 minutes; naturally cool below 25°C.

Embodiment 2

[0028] Mixture solution of trialkoxysilane and tetraalkoxysilane 40%

[0029] 1% Fluorosilane [CF 3 (CF 2 ) 5 CH 2 CH 2 Si(OC 2 h 5 ) 3 】solution 50%

[0030] 30% nano-silica solution 2.0%

[0031] 10% nano-titanium oxide solution 8.0%

[0032] The preparation of the mixture solution of trialkoxysilane and tetraalkoxysilane is the same as in Example 1.

Abstract

A nano-stone protective agent and its production are disclosed. The protective agent consists of mixture solution of tri-alkoxy silane and tetra-alkoxy silane 40-55%, 1% fluoro-silicate solution 30-50%, 30% nano-silicon oxide solution 1.5-3.0%, 10% nano-titanium oxide solution 3.0-8.5% and 1% fluoro-silicate solution as silane coupling agent. It's clean, has better weather resistance and no waste gas discharge.

Description

Technical field: [0001] The invention relates to the technical field of stone protective agents, in particular to a nanometer stone protective agent and a preparation method thereof. Background technique: [0002] The chemical damage of stone generally means that the composition of the stone reacts with other chemical substances, causing the stone to lose its composition, loosen, crack and reduce its physical properties, especially for marble-based marbles, which are the most obvious and the most common example is CaCO in marble 3 and SO in acid rain 2 , CO 2 The reaction will cause the stone to gradually weather and be taken away by water continuously, forming holes, grooves, and cracks; those that cannot be taken away by water will form a sharp and hard cortex, which is different from the original stone structure, and will eventually appear soaked in water and peel off. The shape falls off, and some black layers appear. This kind of chemical damage is most common and m...
