Example Embodiment

[0020] Example

[0021] The high-toughness mortar for wallboards of this embodiment is composed 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 of less than 0.25mm: 90-110 parts;

[0024] Component 3: Water: 45-50 parts;

[0025] Component 4: Polyacrylate latex powder: 1.3-1.7 parts;

[0026] Component 5: Lightweight short fibers of 10-19mm: 0.02-0.06 parts;

[0027] The high-toughness mortar for wallboard is made by first mixing ultra-fine sand with a particle size of less than 0.25mm and polyacrylate latex powder, and then adding part of the water in the third component to stir, until the fine sand is completely covered by the polyacrylate latex powder After wrapping, add all the remaining water in component one, component five and component three and stir it.

[0028] The lightweight short fibers in this embodiment are lightweight fibers...

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...
