Problems solved by technology

At present, the adhesives used in the market mainly have shortcomings such as poor cohesion and crack resistance that cannot meet the requirements, which makes cracks appear at the joints after the wall is installed, which affects the appearance quality of the wall at least, and directly affects the quality of the wall. body structure stability
The quality of lightweight wallboard is of course very important, but if there is no good adhesive to match it, the quality of the wall project is still difficult to guarantee, so the performance of the adhesive determines the quality of the lightweight wall one of the important factors of

Embodiment 1

[0018] A method for preparing an adhesive for lightweight partition wall slats. The following components are weighed in parts by weight: 10 parts of putty paste, 20 parts of vitrified microbeads, 8 parts of cement, 4 parts of wood calcium, and 20 parts of silica sol 2 parts of glycerin, 5 parts of river sand, and then add 5% water of the mass sum of the above components, and stir at 35-45°C for 1-2min to obtain. The resulting product has a shrinkage rate of 0.25% and an expansion rate of 0.5% at a temperature of 50-60°C. After returning to customers, no cracks were found after three years of use.

Embodiment 2

[0020] A method for preparing an adhesive for lightweight partition wall slats. The following components are weighed in parts by weight: 15 parts of putty paste, 30 parts of vitrified microbeads, 10 parts of cement, 7 parts of wood calcium, and 26 parts of silica sol 5 parts of glycerin, 8 parts of river sand, and then add 5-10% water of the mass sum of the above components, and stir at 35-45°C for 1-2min to obtain. The resulting product has a shrinkage rate of 0.23% and an expansion rate of 0.39% at a temperature of 50-60°C. After returning to customers, no cracks were found after four years of use.

Embodiment 3

[0022] A method for preparing an adhesive for lightweight partition wall slats. The following components are weighed in parts by weight: 19 parts of putty paste, 44 parts of vitrified microbeads, 112 parts of cement, 7 parts of wood calcium, and 29 parts of silica sol 5 parts of glycerin, 8 parts of river sand, and then add 5-10% water of the mass sum of the above components, and stir at 35-45°C for 1-2min to obtain. The resulting product has a shrinkage rate of 0.27% and an expansion rate of 0.55% at a temperature of 50-60°C. After returning to customers, no cracks were found after three years of use.

Abstract

The invention belongs to the field of construction materials, and particularly relates to an adhesive for light partition wall battens. The adhesive is prepared from, by mass, 10-20 parts of putty grease, 20-50 parts of glass bead, 8-12 parts of cement, 4-9 parts of wooden calcium, 20-30 parts of colloidal silica, 2-7 parts of glycerinum and 5-10 parts of river sand. The raw materials adopted in the adhesive is easy to obtain, the preparation method gradually changes, the adhesive prepared by the method has a great anti-shrinkage property, and the shrinkage rate is lower than 0.3%; through the synergistic interaction of all the components, the adhesive bonding fastness is improved, and the adhesive can resist high temperature and prevent sun crack. The raw materials contain no organic components, and are safe, environmentally friendly and great in fire resistance; moreover, the raw materials can remain non-inflammable for 3 h according to combustion experiments.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an adhesive for lightweight partition wall strips and a preparation method thereof. Background technique [0002] The light-weight partition wall adhesive for construction is mainly a powder product made of cement and sand as the main raw materials, which are mixed with additives. Adhesive is used as the main material for the installation joint treatment of lightweight partition wall slats. It plays a role in bonding the installation joints of light-weight walls. It is an important material to ensure the overall strength of the partition wall slat wall. It plays an important role in the crack resistance and appearance quality of the body. At present, the adhesives used in the market mainly have shortcomings such as poor cohesion and crack resistance that cannot meet the requirements, which makes cracks appear at the joints after the wall is installed, which affects ...
