Interface agent for mechanized construction

Abstract

The invention provides an interface agent for mechanized construction. The interface agent is prepared from the following components in percentage by mass: 0 to 15 percent of manufactured sand, 45 percent of cement, 37 to 52 percent of powder and the balance of an additive, wherein the grain diameter of the manufactured sand is 0 to 1.2mm. The additive is prepared from 0.01 percent of hydroxypropyl methylcellulose ether, 2.48 percent of redispersible latex powder, 0.01 percent of starch ether, 0.1 percent of woody fiber, 0.2 percent of a thixotropic lubricant and 0.2 percent of a de-foaming agent. By adopting the interface agent, the problem of a bonding force can be solved and a concrete wall surface and wall surfaces made of other wall materials also can synchronously absorb water in a mechanical construction process, so that synchronous initial setting of different wall materials is ensured and cracking and hollowing phenomena caused by the fact that the shrinkage of wall bodies isdifferent are avoided; and a work slowdown phenomenon of workers is reduced and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a novel interface mortar formula and a preparation method. Background technique [0002] The interface agent is a kind of adhesive, which has super strong adhesive force, excellent water resistance and aging resistance. It is used to improve the bonding strength of the plastering mortar to the base layer, which can effectively avoid problems such as hollowing, falling off, shrinkage and cracking of the plastering layer. It is used to treat the surface of concrete, aerated concrete, lime-sand brick and fly ash brick, etc., to solve the problem that the interface is not easy to bond due to the strong water absorption or smoothness of these surfaces, resulting in hollowing, cracking and falling off of the plastering layer. It can greatly enhance the bonding force between old and new concrete and between concrete and plastering mortar. It can replace the chiseling p...

AI Technical Summary

Problems solved by technology

[0003] The traditional interface agent used in the market is a formula designed to solve the bonding force between mortar and concrete, but the bonding force of plastering mortar (mainly machine-made sand as raw material) used in mechanized construction Far greater than artificial plastering mortar, direct construction on the concrete wall will not cause insufficient adhesion, but because the water absorption of the concrete wall is very slow, it takes a lot of time to wait for the wall to dry after the mortar is applied to the wall. Initial setting, this is easy to cause the construction team to slack off
