Problems solved by technology

Moreover, the curing process of the geopolymer coating is carried out under natural (except special) conditions. Factors such as ambient temperature and humidity cannot meet the ideal conditions for the geopolymer binder to cure into a coating film. The mechanical properties of the geopolymer The properties are not fully utilized, and the coating film is prone to surface defects such as filler exposure, shedding and cracking
The flexibility and leveling of geopolymer coatings are difficult to approach the performance indicators of organic coatings

[0139] 22kg metakaolin, 30kg modulus=1.2 sodium silicate dry powder resin, 5kg modulus=1.6 potassium silicate dry powder resin, 1kg modulus=1.5 lithium silicate dry powder resin, 2kg sodium hydroxide, 1kg potassium hydroxide , 0.5kg lithium hydroxide, 3kg VINNAPAS ⑧ RI551 Z, 0.3kg SILRES ⑧ BS Powder A, 0.6kg Na 5 P 3 o 10 、0.06kg AGITAN ⑧ P803, 0.6kg MELMENT F10, 0.2kg PMC-15US, 4kg NaSiF 6 Concentrated mixing, crushing and processing to become geopolymer coating binder.

Embodiment 2

[0141] With 36kg metakaolin, 30kg modulus=1.2 sodium silicate dry powder resin, 5kg modulus=1.6 potassium silicate dry powder resin, 1kg modulus=1.5 lithium silicate dry powder resin, 2kg sodium hydroxide, 1kg potassium hydroxide , 0.5kg lithium hydroxide, 0.8kgNa 5 P 3 o 10 、0.06kg AGITAN ⑧ P803, 0.45kg MELMENT F10, 6kg NaSiF 6 After centralized mixing, it is pulverized and processed to become a geopolymeric coating coating agent.

Embodiment 3

[0143] Put 30kg of geopolymer coating coating agent, 5kg of titanium dioxide, 0.01kg of ultramarine blue and water into the mixing tank under stirring state, stir to form a uniform paste and pour it into a mold of 200mm×200mm×200mm. After the paste is finally set, put the mold into a pressure tank and harden at 95°C for 24 hours. After hardening, demould and pulverize to d≤15μm, and dry to a moisture content of ≤2%, send it to the mixer, and then Add 35kg of geopolymer paint binder and 0.1kg of polypropylene staple fiber for mixing, and the mixing uniformity is ≤1%, and then the material is packaged. This example is a crack-resistant and waterproof white architectural coating.

Abstract

This invention relates to a dope combination. The film coating it formed is amorphous gelatinous substance, base unit is three-dimensional network formed by connection of silicon - oxygen tetrahedron and aluminium - oxygen tetrahedron. end product takes electrovalent bond and covalent bond as main, vander waas bond as complement, possess linkage structure of organic heavy polymer, and double property of inorganic polymer and organic polymer. The unique performance supple the insufficiency of organic high molecular polymer. It possesses favorable performance of acid-proof, alkali-proof, impervious, antifreeze, seawater resistance and high temperature resistance.

Description

technical field [0001] The invention relates to an inorganic coating, in particular to a geopolymeric coating composition with an organic macromolecule polymer bonding structure and a preparation method thereof. Background technique [0002] The coatings industry is a material-intensive manufacturing industry. Most organic paints use materials that are harmful to humans and the environment during their manufacture. Most of the harmful materials will volatilize into the atmosphere during the manufacture, construction or after construction of organic coatings, and the resulting adverse impact on the environment has attracted worldwide attention. At the same time, the manufacture of organic coatings also consumes a large amount of natural resources, especially petroleum resources, so people's research focus has turned to inorganic coatings. Inorganic coatings have many advantages, and their excellent performance in environmental protection, functionality, and technical and ec...
