Problems solved by technology

Coatings with water-soluble resins as adhesives, such as 106 and 107 coatings, have relatively low cost, but they have disadvantages such as water resistance, scrub resistance, weather resistance, poor adhesion, easy pulverization, peeling, and yellowing; Although the performance of the coating with synthetic resin emulsion as adhesive is good, the production process is complicated and the cost is high, so its popularization and use have been greatly restricted.
In short, whether it is solvent-based paint or water-based paint, its formula contains organic compounds, which will more or less cause harm to the human body. At the same time, liquid paints still have the problem of inconvenient transportation and difficult storage.

Embodiment 1

[0026] Select high-quality natural magnesite without impurities and place it in a calcination kiln for calcination at a constant temperature of 800-1000°C for 4 hours. After cooling, it exits the kiln to produce light-burned magnesia.

[0027] Take 100Kg of light-burned magnesium oxide, 30Kg of magnesium chloride hexahydrate, 5Kg of borax decahydrate, and 1Kg of iron oxide, and use a grinder to grind them into 300-500-mesh powders, mix them and pack them in bags with moisture-proof inner film according to the measurement of 25Kg In-house products.

[0028] Take 50Kg of the product, add 200Kg of water, stir and mix evenly, then spray and apply it on the inner and outer walls of the building.

Embodiment 2

[0030] Select high-quality natural magnesite and brucite without impurities and place them in a calcination kiln, and calcine at a constant temperature of 1000-1200°C for 4 hours, and then leave the kiln after cooling to produce light-burned magnesia.

[0031] Take 100Kg of light-burned magnesium oxide, 50Kg of magnesium chloride hexahydrate, 10Kg of borax decahydrate, and 3Kg of iron oxide, and grind them into 300-500-mesh powder with a grinder, mix them well, and pack them in a packaging bag with a moisture-proof inner film according to the measurement of 30Kg In-house products.

[0032] Take 50Kg of the product, add 100Kg of water, stir and mix evenly, then spray and apply it on the plywood.

Embodiment 3

[0034] Select high-quality natural magnesite and hydromagnesite without impurities and place them in a calcination kiln, calcine at a constant temperature of 900-1200°C for 4 hours, and then leave the kiln after cooling to produce light-burned magnesia.

[0035] Take 100Kg of light-burned magnesium oxide, 40Kg of magnesium chloride hexahydrate, 3Kg of borax decahydrate, and 2Kg of iron oxide, and use a grinder to grind them into powders of 300-500 meshes, mix them and pack them in bags with moisture-proof inner film according to the measurement of 50Kg In-house products.

[0036] Take 50Kg of the product, add 50Kg of water, stir and mix evenly, then spray and apply it on the ground.

Abstract

The present invention discloses one kind of water soluble solid paint powder for protecting and decorating building surface and its preparation process. The paint powder is prepared through the following steps: constant temperature calcining magnesite, brucite or hydromagnesite with low impurity content to obtain light burning magnesia; adding magnesium chloride hexahydrate, borax decahydrate, iron oxide or other inorganic pigment; grinding in a grinder to 300-500 mesh and packing. The water soluble solid paint powder has simple preparation process, high waterproof and fireproof property, high wear resistance, high strength and other advantages, and may be used widely in building.

Description

technical field [0001] The invention relates to a paint for construction, in particular to a water-soluble solid powder paint which can be sprayed and coated on the surface of building materials and has the functions of protection and decoration. Background technique [0002] As we all know, the so-called coating refers to a material that can be coated on the surface of an object by a specific construction method and cured to form a continuous coating film, through which the coated object can be protected, decorated and other special functions. Classification by formulation includes solvent-based coatings and water-based coatings. More than half of the solvents used in solvent-based paints are hydrocarbons, and the rest are ketones, alcohols, glycol ethers, esters, nitro straight-chain hydrocarbons and a small amount of other substances. The characteristic of water-based coatings is that water is used as a solvent, thus avoiding various unfavorable factors such as flammabil...
