Problems solved by technology

However, there is no special adhesive for bonding magnesium walls made of magnesium gel materials on the market. Therefore, a kind of adhesive that is suitable for magnesium wall materials is developed, which is environmentally friendly, has excellent performance, and has good weather resistance. The adhesive is very important

preparation example 1

[0036] In this preparation example, the magnesium wall adhesive uses the following raw material components in parts by weight: magnesium oxide: 100 parts, magnesium sulfate solution: 83 parts, phosphoric acid: 2 parts, sodium phosphate: 2 parts, 108 glue: 10 parts , Rubber powder: 10 parts, concrete interface agent: 5 parts, sawdust: 3 parts, fly ash: 8 parts, glass fiber: 1 part, water: 10 parts.

[0037] During preparation, magnesium sulfate heptahydrate is dissolved in water to prepare a magnesium sulfate solution with a Baume degree of 29, and then the magnesium sulfate solution is added into a reaction kettle. Then, add magnesium oxide into the reaction kettle and stir evenly, then add phosphoric acid, sodium phosphate, 108 glue, rubber powder, and concrete interface agent into the reaction kettle at one time, and stir at 650rpm for 25min to make the components in the reaction kettle fully Dissolve and mix. Next, add straw or sawdust, fly ash, glass fiber, and water into...

Abstract

The invention provides an adhesive for magnesian wall and a preparation method of the adhesive. The adhesive is prepared from the components in parts by weight: 100-200 parts of magnesium oxide, 80-170 parts of magnesium sulfate solution, 1-5 parts of phosphoric acid, 1-5 parts of sodium phosphate, 10-20 parts of 108 glue, 10-20 parts of rubber powder, 2-8 parts of concrete interface agent, 3-7 parts of straw or sawdust, 7-16 parts of coal ash, 1-2 parts of glass fiber and 10-25 parts of water; the magnesium sulfate solution is prepared from magnesium sulfate heptahydrate, and the molar ratioof the magnesium oxide and the magnesium sulfate heptahydrate is 6 to 1. The adhesive for magnesian wall has the advantages of high bonding strength and good weather resistance and water resistance, and is suitable for magnesian wall materials, connection performance is stable, and good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an adhesive for magnesium walls. At the same time, the invention also relates to a preparation method of the adhesive. Background technique [0002] Construction adhesive is a kind of adhesive, and it is also an essential material for construction engineering. It is mainly used for sealing various joints or holes in buildings to prevent gas, liquid, and solid from penetrating, and to prevent structural materials from When the structure is displaced, it is destroyed, so as to play the functions of heat preservation, sound insulation, waterproof, dustproof, gasproof, fireproof, anticorrosion, shock absorption and preventing the joints from accumulating foreign matter. [0003] Currently commonly used construction adhesives usually have high production costs and poor environmental adaptability, and have gradually been unable to meet the needs of modern society for constr...
