Embodiment

[0021] A kind of high-toughness mortar for exterior decoration of the present embodiment, the high-toughness mortar for exterior decoration 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 below 0.25mm: 90-110 parts;

[0024] Component three: water: 40-45 parts;

[0025] Component four: EVA latex powder: 0.4-0.6 parts;

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

[0027] The high-toughness mortar is used for the exterior surface by first mixing the ultra-fine sand with a particle size of less than 0.25mm and EVA latex powder evenly, and then adding part of the water in component 3 to stir until the ultra-fine sand is completely wrapped by EVA latex powder , and then all the remaining water in components 1, 5 and 3 are added and stirred.

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

Abstract

The invention relates to a high-toughness mortar for exterior facing, and belongs to the technical field of mortar in chemistry. The high-toughness mortar for exterior facing comprises the following components in parts by mass: 90-110 parts of component 1, 90-110 parts of component 2, 40-45 parts of component 3, 0.4-0.6 part of component 4 and 0.02-0.06 part of component 5, wherein the component 1 is a mixture of 90% of ordinary silicate cement and 10% of coal ash powder or 10% of limestone powder; the component 2 is superfine sand of which the particle size is below 0.25mm; the component 3 is water; the component 4 is EVA (ethylene-vinyl acetate) latex powder; and the component 5 is 10-19mm light weight short fiber. A preparation method of the high-toughness mortar for exterior facing comprises the following steps: uniformly stirring the superfine sand of which the particle size is below 0.25mm and the EVA latex powder; then adding part of the water in the component 3; stirring until the superfine sand is completely wrapped by the EVA latex powder; adding the component 1, the component 5 and the remaining water in the component 3 altogether; and stirring to obtain the finished product. The high-toughness mortar for exterior facing has the advantages of favorable binding force, small shrinkage value and good weather resistance.

Description

technical field [0001] The invention relates to a high-toughness mortar for exterior decoration, 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 pre...
