Embodiment 1

[0025] An inorganic polymer resin, comprising the following components in weight ratio:

[0026] 55 parts of potassium silicate, 12 parts of water glass, 15 parts of silane coupling agent, 4 parts of lithium magnesium silicate, 6 parts of potassium tripolyphosphate, 11 parts of aminoacrylic acid and 0.5 part of trimethylolpropane.

[0027] By adding a silane coupling agent, the strength of the inorganic polymer resin can be improved; potassium silicate is the main component, so that the obtained inorganic polymer resin has high alkali resistance and strong moisture absorption capacity; the silane coupling agent is an active agent , carry out hydrolysis reaction, single potassium silicate can combine with each other to form aggregates with a chain structure, the molecular weight can reach 7000-10000, so that the inorganic polymer resin has high strength, and it is beneficial to improve the surface dispersion during use.

Abstract

The invention discloses an inorganic polymer resin. The inorganic polymer resin comprises, by weight, 50-60 parts of potassium silicate, 10-15 parts of water glass, 10-20 parts of a silane coupling agent, 3-5 parts of magnesium lithium silicate, 3-8 parts of potassium tripolyphosphate, 8-15 parts of aminoacrylic acid and 0.2-0.8 part of trimethylolpropane. The preparation method of a water-based coating comprises the following steps: S1, preparing the inorganic polymer resin; and S2, mixing 20-30 parts of the inorganic polymer resin prepared in step S1 with the following components according to a certain ratio: cellulose, a dispersing agent, a wetting agent, rutile titanium dioxide, calcium carbonate, kaolin, a silicone acrylic emulsion, an antifoaming agent, a thickener, a leveling agentand water. Potassium silicate is used as a main component, the silane coupling agent is adopted as an activator, and through a mutual reaction, the single potassium silicate can be mutually combined to form the aggregate having a chain structure, and the molecular weight can achieve 7000-10000, so the coating has the characteristics of excellent physical properties, high alkali resistance and dewformation resistance, and can be widely used in building interior walls.

Description

technical field [0001] The invention belongs to the field of preparation of water-based paint, in particular to a preparation method of inorganic polymer resin and water-based paint. Background technique [0002] With people's emphasis on environmental protection and energy, water-based coatings have become an important direction for the development of coatings. Water-based paints are gradually replacing solvent-based paints because of their non-pollution to the environment and safety in production and use. At present, many water-based coatings used for interior walls of buildings on the market are prone to condensation during use, especially in the relatively humid environment in the south, which will affect the use. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a high alkali resistance and anti-condensation nanomaterial composite inorganic polymer water-based coating that can solve at least one of the above p...
