Meanwhile, the material has the functions of micro-expansion and compactness increasing, and can be widely applied to the following fields:
1. the waterproof and moistureproof composite material is widely suitable for roofs, inner and outer walls, floors, toilets, kitchens, basements and warehouses and is also suitable for the barrier and seepage prevention of reinforced concrete structures;
2. for underground civil air defense engineering: such as culverts, bridges, dams, tunnels, large hydropower stations and water diversion works, to reduce water erosion and prevent weathering;
3. for various pools: such as swimming pools, clean water tanks, sewage tanks, water towers, etc.;
4. for superabsorbent inorganic aggregates: such as perlite plates, roof bricks, cement bricks, high-rise building light brick veneers, asbestos, inorganic fabrics, heat-insulating materials and the like, so that the waterproof and moistureproof effects are remarkable;
5. the water-soluble building paint is used for water resistance, color protection, pollution prevention and aging prevention, and is widely used for exterior wall veneering;
6. the additive used for emulsion paint, water glass and 107 glue can ensure that the emulsion paint has obvious hydrophobicity and can keep stable bonding strength;
7. the slurry is used for petroleum drilling, the viscosity and the density of the slurry can be adjusted, the collapse of the drilling can be effectively prevented, and the drilling rate is improved;
8. the device is used for pumping and injecting an oil production layer at the later stage of an oil well, and prevents a crust skeleton of the oil production layer from collapsing, so that oil far away from the oil well can be smoothly produced;
9. used for other special purposes for reducing water absorption and resisting permeability and water.
The sodium methyl silicate stock solution in the market still has obvious waterproof performance when 8 times of water is added, but the waterproof function is obviously reduced when the water is more than 8 times, and when the sodium methyl silicate stock solution is used for high-quality materials such as inorganic fabrics and the like, higher-quality sodium methyl silicate is needed, namely, the purity is high, impurities are few, and the liquid permeability is high; as well as permeability in terms of performance and more excellent waterproofing effect. Therefore, the method has good market prospect for improving the quality of the sodium methylsilicate on the premise of not increasing the cost of the sodium methylsilicate.
The currently common method for producing sodium methylsilicate is as follows: one heating and stirring tank, methyl silicic acid, sodium hydroxide, a catalyst and water are mixed, heated and stirred for 5 hours, a finished product of sodium methyl silicate is obtained after cooling, the finished product of sodium methyl silicate has turbidity, the permeability is poor after filtering, impurities obviously exist, the sodium methyl silicate can only be used for conventional waterproof action, and the power consumption during heating also causes the increase of production cost.
