Abstract

The invention discloses water-based inorganic resin and a preparation method thereof. The preparation method comprises the following steps: carrying out hydrolysis reaction on a formula amount of potassium silicate, silica sol and lithium silicate under the effect of a coupling agent, and after reaction is stable, adding elastic emulsion so as to adjust the flexibility, thus obtaining the water-based inorganic resin with excellent properties. The water-based inorganic resin prepared by the method is environment-friendly, odorless, non-toxic, non-ignitable and unexplosive, and has very excellent salt fog resistance, permanent corrosion resistance, high hardness, strong adhesive force and heat and humidity resistance, and therefore, the water-based inorganic resin has wide development space in numerous heavy corrosion protection fields and atmosphere and ocean steel structure heavy corrosion protection fields.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based inorganic resin and a preparation method thereof. Background technique [0002] In recent years, as people pay more and more attention to environmental protection, high-performance water-based product resins have been extensively researched and developed. [0003] The water-based inorganic resins currently researched and developed include silica sol sodium water glass, potassium sodium water glass, lithium water glass, or a mixture of several types. Sodium silicate is easily soluble in water, and the paint film has poor water resistance; potassium silicate is soluble in water, and the price is moderate; lithium silicate is expensive, and it is not suitable for water solubility, and the concentration is low. The products obtained by simple mixing have poor stability, poor adhesion, or certain problems in water resistance and flexibility. Contents of the invention...
