Embodiment

[0021] A kind of high-toughness mortar for wallboard of the present embodiment, this high-toughness mortar for wallboard consists of the following components by mass,

[0022] Component 1: a mixture of 90% ordinary Portland cement and 10% coal ash powder: 90-110 parts;

[0023] Component 2: ultra-fine sand with a particle size below 0.25mm: 90-110 parts;

[0024] Component three: water: 45-50 parts;

[0025] Component four: polyacrylate latex powder: 1.3-1.7 parts;

[0026] Component five: 10-19mm lightweight staple fiber: 0.02-0.06 parts;

[0027] The wallboard uses high-toughness mortar by first mixing the ultra-fine sand with a particle size of less than 0.25mm and polyacrylate latex powder evenly, and then adding part of the water in component 3 to stir until the fine sand is completely covered with polyacrylate latex powder. After wrapping, add all the remaining water in components 1, 5 and 3 and stir.

[0028] The light-weight staple fibers of this embodiment are lig...

Abstract

The invention relates to high-toughness mortar for a wallboard and belongs to the technical field of mortar in chemistry. The high-toughness mortar for the wallboard consists of the following components by mass: 90-110 parts of a component I: a mixture of 90% of ordinary Portland cement and 10% of coal ash powder or 10% of limestone flour; 90-110 parts of a component II: superfine sand with the grain size of 0.25 mm or below; 45-50 parts of a component III: water; 1.3-1.7 parts of a component IV: polyacrylate emulsion powder; and 0.02-0.06 part of a component V: light-weight short fiber of 10-19 mm. According to the high-toughness mortar for the wallboard, the superfine sand with the grain size of 0.25 mm or below and the polyacrylate emulsion powder are uniformly stirred at first, then part of water in the component III is added, stirring is performed, after that, the component I, the component V and the rest water in the component III are all added after the superfine sand is completely wrapped with the polyacrylate emulsion powder, and stirring is conducted to form the high-toughness mortar. The high-toughness mortar for the wallboard has the advantages that the adhesive property is good, the shrinkage value is small and the weather fastness is excellent.

Description

technical field [0001] The invention relates to a high-toughness mortar for wall boards, which belongs to the technical field of mortar in chemistry. Background technique [0002] Mortar is used in almost every part of the building, from structure to decoration, from roof, wall to ground. In the current architectural decoration, tiles are used in many parts of the building. The traditional tile adhesive is ordinary mortar. The traditional tile paste process is based on ordinary mortar made of a mixture of sand, cement and water on the construction site. After the ordinary mortar is applied to the back of the tile, the tile is pressed Put it on the wall for a certain period of time, let the cement penetrate into the pores on the back of the tile and start to solidify to form a light bond. According to the applicant's knowledge, the bonding performance of ordinary mortar is very poor. Contents of the invention [0003] The technical problem to be solved by the present inv...
