Abstract

The invention discloses a bi-component environment-friendly inorganic polymer coating material and a preparation method thereof. When being used for thick-layer coating processes (roll coating, knife coating and spray finishing) or thin-layer coating processes (brush coating and spray finishing), the coating material is prepared by mixing a prepared component A and a prepared component B at a weight ratio of (1.6-1.8):1 or (0.7-0.8):1. The component A is prepared by mixing 25-35 or 65-85 parts by weight of calcined kaolin, 1-2 parts by weight of pigment, 1-2 or 2-4 parts by weight of hardening accelerator and 55-75 or 8-35 parts of filler, and fully stirring the mixture. The component B is prepared by fully stirring 2-4 parts by weight of thickening agent and 96-98 parts by weight of excitant solution. The coating material prepared by the method has the properties of heat resistance, acid-base resistance, water resistance, freeze-thaw cycle resistance and the like, has the advantages of decorative performance, low cost and no pollution to environment, and belongs to an environment-friendly material.

Description

technical field [0001] The invention relates to a two-component environment-friendly inorganic polymer coating material for building surface protection and a preparation method thereof, belonging to the field of chemical gelling materials. Background technique [0002] In order to improve the weather resistance, corrosion resistance and durability of various structural materials (including cement concrete, wall materials, steel) on the surface of buildings, as well as decorative considerations, it is generally necessary to coat the surface with paint. At present, organic coatings account for the vast majority of the market, which can be divided into powder coatings, alkyd (polyester) resin coatings, amino (alkyd, polyester) resin coatings, and acrylic resin coatings according to their film-forming substances. , polyurethane resin coatings, epoxy resin coatings, silicone resin coatings, vinyl resin coatings, fluorocarbon coatings, etc. Among them, the most widely used exterio...
