Abstract

The invention discloses an interface agent for a fabricated wallboard. The interface agent is prepared from the following components in parts by mass:30-60 parts of permeable acrylic emulsion, 10-15 parts of an active material, 10-20 parts of a retarder, 10-20 parts of barium sulfate, 150-180 parts of talcum powder, 10-20 parts of titanium dioxide, 120-170 parts of water and a proper amount of anauxiliary agent. After the process of the interface agent is adopted, the formula cost of the bonding mortar can be greatly reduced, and only the bonding mortar is required to have good bonding strength and self-strength slightly higher than that of a light wallboard. And in combination with the interface agent, the cost can be reduced by half or more than half of the original cost.

Description

technical field [0001] The invention belongs to the technical field of interface agents for assembled wallboards, and in particular relates to an interface agent for assembled wallboards and its preparation method and application. Background technique [0002] As the policy increases support, vigorously promote prefabricated buildings. In this context, a large number of prefabricated building-related processes and materials have been developed one after another, and decoration building materials tend to be lightweight and humanized. Among them, the application of lightweight partition boards is the main type of fully prefabricated buildings in the industrialized building system. . The application of lightweight partition boards can greatly reduce the weight of the building, save consumables and reduce the cost of the project. It is easy to produce mechanically and is greatly favored by the construction market. [0003] The applicant found that the existing lightweight part...
