EPS line mechanical plastering dedicated mortar

Abstract

The invention provides an EPS line mechanical plastering dedicated mortar. The mortar is composed of the following components in parts by weight: 300 to 350 parts of cement, 400 to 500 parts of quartz sand, 100 to 200 parts of heavy calcium carbonate powder, 30 to 60 parts of ash calcium powder, 10 to 15 parts of redispersable latex powder, 2 to 4 parts of cellulose ether, 3 to 5 parts of wood fiber, 1 to 3 parts of dispersant, 3 to 5 parts of wetting agent, and 0.3 to 0.5 part of foam stabilizer. The EPS line mechanical plastering dedicated mortar has the advantages of good flexibility and good binding property, and above all, the mortar can well cooperate with an EPS line plastering machine. The EPS line produced by an EPS line plastering machine has the advantages of no pendant, no sagging, no cracking in the internal angle of lines, almost no bubble in the surface, and fine and smooth appearance.

Description

technical field [0001] The invention relates to a construction mortar, in particular to a special mortar for mechanical plastering with EPS lines. Background technique [0002] EPS line is a kind of facade decoration product used in ordinary houses, villas, hotels, and shopping malls. It can be decorated on the four sides of the window, the door, the hall wrapping pillars, the corner lines, etc., which can make the facade of the building more rich. Creative, more beautiful. EPS lines have many edges and corners. Only by using mechanical plastering method, that is, applying special mortar to each corner and surface of EPS lines at one time, can mass-produce EPS lines with low price and meet the exterior design of buildings. Generally, polymer mortar is applied to EPS lines, and there will be some difficulties in several links such as stirring, mechanical plastering, and EPS lines being stored and dried. Bubbles with uneven pore size appear in the mortar during the process o...

AI Technical Summary

Problems solved by technology

During the process of adding water and stirring, there will be bubbles with uneven pore size in the mortar, and in the process of mechanical plastering, spots and strips will be left on the surface of the lines, which will seriously affect the appearance quality of EPS lines.

Improper consistency and fluidity of the mortar will lead to poor smoothness during mechanical plastering, and the surface of the produced EPS lines will be rough

The particle size composition of the mortar is not well controlled, the particle size is too large, the mortar surface is not smooth and delicate; the particle size is too small, the mortar is easy to aggregate and difficult to disperse evenly, and the inner corner of the line is easy to crack

When the EPS line is stored and dried, the mortar is not dry and solidified, and there will be sagging and corner drop phenomenon
