example 1

[0025] Mix glucose and water in a three-necked flask with a mass ratio of 1:30, and add potassium periodate 0.03 times the mass of glucose to the three-necked flask. Nitrogen gas was introduced into the three-necked flask at a rate of 25 mL / min, and the temperature was 40. ℃, the rotating speed is 350r / min, after stirring and reacting for 14h, the pretreated glucose mixture is obtained. The pretreated glucose mixture and the 15% barium chloride solution are mixed at a mass ratio of 1.0:1.6 at the rotating speed Under the condition of 350r / min, after stirring and mixing for 30 minutes, filter to obtain a pre-modified glucose mixture. Mix the pre-modified glucose mixture with a sodium sulfate solution with a mass fraction of 18% at a mass ratio of 1.0:1.8. Under the condition of 380r / min, after stirring and mixing for 50 minutes, filter and remove the precipitate, the modified glucose solution is obtained; after the mixed powder is calcined for 20 hours, the pretreated mixed powde...

Abstract

The invention discloses a preparation method of a water-resistant inorganic sodium silicate adhesive, and belongs to the technical field of inorganic adhesion materials. By weight, 50-60 parts of sodium silicate, 10-12 parts of sodium fluorosilicate, 5-8 parts of a reducing agent, 40-60 parts of water, 5-8 parts of polydimethyl siloxane, 3-4 parts of a dispersing agent, 15-22 parts of modified powder and 8-15 parts of a modified glucose solution are weighed in sequence; the water is mixed with the modified glucose solution, the modified powder and the reducing agent are added, and after stirring is conducted for a reaction, a billet liquid is obtained; the billet liquid is mixed with the sodium fluorosilicate, the sodium silicate and the dispersing agent are added, and the water-resistantinorganic sodium silicate adhesive is obtained after stirring and mixing. By means of the method, the obtained water-resistant inorganic sodium silicate adhesive has excellent adhesion properties andwater resistance.

Description

Technical field [0001] The invention discloses a preparation method of a water-resistant inorganic sodium silicate adhesive, which belongs to the technical field of inorganic bonding materials. Background technique [0002] Sodium silicate, commonly known as Sodium Silicate, is a water-soluble silicate, and its aqueous solution is commonly known as water glass, which is a mineral binder. Its chemical formula is R 2 O·nSiO 2 , Where R 2 O is an alkali metal oxide, n is the ratio of the number of moles of silica to the number of alkali metal oxides, which is called the number of moles of water glass. The commonly used water glass in construction is sodium silicate (Na 2 O·nSiO 2 ) In aqueous solution. [0003] The use of water glass is very extensive, almost in all sectors of the national economy. In the chemical system, it is used to produce various silicate products such as silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, laye...
