Abstract

The invention provides a curing-time-adjustable coating-free gypsum board installation adhesive. The curing-time-adjustable coating-free gypsum board installation adhesive comprises a water glass solution, a curing agent, a lubricant, polyvinyl alcohol, a filler and a silane coupling agent. The cross-linking agent provided by the invention can be used for bonding two gypsum plaster boards, and also can be used for bonding the gypsum plaster boards and wood. Nailing or buckle mounting or organic adhesive introduction on the gypsum plaster board is avoided, the requirement of the gypsum plaster board for nail-holding power is lowered, and pollution to the indoor environment caused by volatilization of organic substances is avoided.

Description

technical field [0001] This article relates to but not limited to the technical field of inorganic adhesive materials and installation technology of gypsum boards, especially relates to but not limited to an inorganic adhesive for coating-free gypsum board installation with adjustable curing time and its preparation method. Background technique [0002] Coating-free gypsum board is a board made of building gypsum as the main raw material, mixed with a small amount of fiber materials, etc., with various patterns and floral decorations. It can avoid secondary painting, and it can be installed and lived immediately after installation. At present, the installation methods of paint-free gypsum board mainly include nailing method and pasting method. The nailing method requires keels and screws to assist in the installation, which has high requirements for the nail-holding force of the board and has a certain damage to the board. The paste method is currently mainly installed with...
