preparation example Construction

[0031] The preparation method of composite paint body base material comprises the steps:

[0032] (1) At 28~35°C, take phenol and ammonia solution with a mass fraction of 12% at a mass ratio of 5~8:3 and mix them in a reaction kettle to obtain a mixed solution, raise the temperature to 60~75°C, and add 20~35% of the mixed solution formaldehyde and melamine with a mass of 10-15% of the mixed liquid, stirred magnetically at 450-800r / min for 40-60min, raised the temperature to 80-95°C, and added nano-TiO with a mass of 4-8% of the mixed liquid 2 1. Mix boric acid with a mass of 8-14%, magnetically stir at 500-800r / min for 25-40min, heat up to 150-165°C, keep warm for 1-3h, and discharge to obtain a modified phenolic resin;

[0033] (2) Mix modified phenolic resin, carbodiimide and polyacrylic acid zinc resin in a mixer at 20~35°C according to the mass ratio of 6~9:1:4, and stir magnetically at 500~800r / min for 1~ 3h, heat up to 40~55°C, add reagent A which is 2~5 times the mass ...

Abstract

The invention discloses heat-insulating and anticorrosive real-stone coating and belongs to the field of building materials. In the invention, phenolic resin is modified by boric acid, nano TiO2 and the like, so that internal stability is improved; by combination of inorganic stone material, anti-external erosion effect is greatly enhanced, and the heat resistance of the macromolecular paint basematerial is improved; raw materials, such as talc, mullite and mica, are subjected to high-pressure and high-temperature treatment to obtain a high-stability cordierite structure; functional modification is combined and a similar passivating treatment is supplied so as to improve the anticorrosive effect; the stone material is subjected to fermenting modification by watermelon juice and active sludge in order to generate free polar groups, aromatic rings and the like, so that internal stability is enhanced; groups are introduced through microbial crosslinking so as to improve the compatibilitywith the organic paint material, thereby improving the anticorrosive and heat-insulating effect in the tissue for a long lasting time. The invention solves the problems of poor heat-insulating and anticorrosive performance of common real-stone coatings in the prior art.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a heat-insulating and corrosion-resistant real stone paint. Background technique [0002] With the development of society and the improvement of people's lives, green buildings have become a development trend in the future of buildings. Real stone paint, as a bionic material with a decorative effect similar to granite and marble, is increasingly used by real estate developers and interior and exterior designers as exterior wall coatings. In modern high-end building exterior wall decoration, compared with traditional tiles and dry hanging stones, real stone paint has the advantages of convenient construction, low cost, safety and non-toxicity, natural and generous, durable, and good decorative effect. Favored by customers. Real stone paint is based on one or more synthetic resin emulsions, adding a small amount of film-forming aids as bonding materials, using different grades o...
