Embodiment

[0019] A kind of mortar for exterior decoration of this embodiment, the mortar for exterior decoration is composed of the following components by mass,

[0020] Component 1: a mixture of 90% ordinary Portland cement and 10% coal ash powder: 90-110 parts;

[0021] Component 2: a mixture of one part of medium sand with a particle size of 0.5-0.35mm and two parts of extra-fine sand with a particle size of less than 0.25mm: 90-110 parts;

[0022] Component three: water: 40-45 parts;

[0023] Component four: EVA latex powder: 0.4-0.6 parts;

[0024] The mortar for exterior decoration is firstly mixed with EVA latex powder in component two, and then mixed with part of the water in component three. All the remaining water in components 1 and 3 are added and stirred.

Abstract

The invention relates to relates to mortar for exterior facing and belongs to the technical field of mortar in chemistry. The mortar for the exterior facing is prepared from the following components by mass: component I: 90-110 parts of a mixture of 90% of ordinary Portland cement and 10% of coal ash or 10% of limestone powder; component II: 90-110 parts of a mixture of one part of medium sand with particle size being 0.5-0.35 mm and two parts of superfine sand with particle size being 0.25 mm or less; component III: 40-45 parts of water; component IV: 0.4-0.6 parts of EVA latex powder. The mortar for the exterior facing is prepared by steps as follows: mixing the component II with the EVA latex powder evenly, adding part of water in the component III for mixing, and adding the component I and all remaining water in the component III for mixing after the medium sand and the superfine sand are completed covered with the EVA latex powder. The mortar for the exterior facing has the advantages of good cohesive force, small shrinkage value and good weather resistance.

Description

technical field [0001] The invention relates to a 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 present invention ...
