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

[0023] A method for preparing an environmental-friendly adhesive for anti-drying and cracking lightweight partition wall slats. The following components are weighed in parts by weight: 10 parts of alum stone, 5 parts of mica powder, 15 parts of guar gum, and propylene glycol alginate 3 parts, 8 parts of Indian gum, 10 parts of silica, 5 parts of calcium oxide, 2 parts of reinforcing fiber, 8 parts of cement, 4 parts of wood calcium, 2 parts of water retaining agent, 20 parts of silica sol, 12 parts of river sand, and then add It is obtained by stirring 2-4% water of the above-mentioned components by weight at 35-45°C for 1-2min. The resulting product has a shrinkage rate of 0.4% and an expansion rate of 0.6% at a temperature of 50-60°C. Revisiting customers, after three years of use, no cracks, bulges, shedding, or delamination were found.

Embodiment 2

[0025] A method for preparing an environmental-friendly adhesive for anti-drying and cracking lightweight partition wall slats. The following components are weighed in parts by weight: 15 parts of alum stone, 8 parts of mica powder, 17 parts of guar gum, and propylene glycol alginate 5 parts, Indian gum 10 parts, silica 12 parts, calcium oxide 10 parts, reinforcing fiber 5 parts, cement 10 parts, wood calcium 5 parts, water retaining agent 3 parts, silica sol 24 parts, river sand 18 parts, then add It is obtained by stirring 2-4% water of the above-mentioned components by weight at 35-45°C for 1-2min. The resulting product has a shrinkage rate of 0.34% and an expansion rate of 0.42% at a temperature of 50-60°C. Returning to customers, after four years of use, no cracks, bulges, shedding, or delamination were found.

Embodiment 3

[0027] A method for preparing an environmental-friendly adhesive for anti-drying and cracking lightweight partition wall slats. The following components are weighed in parts by weight: 10 parts of alum stone, 8 parts of mica powder, 17 parts of guar gum, and propylene glycol alginate 5 parts, Indian gum 10 parts, silica 12 parts, calcium oxide 9 parts, reinforcing fiber 5 parts, cement 8 parts, wood calcium 5 parts, water retaining agent 2 parts, composite sol 20 parts, river sand 20 parts, then add It is obtained by stirring 2-4% water of the above-mentioned components by weight at 35-45°C for 1-2min. The resulting product has a shrinkage rate of 0.31% and an expansion rate of 0.55% at a temperature of 50-60°C. Revisiting customers, after three years of use, no cracks, bulges, shedding, or delamination were found.

Abstract

The invention belongs to the field of building materials, and specifically relates to an adhesive for an environment-friendly anti-suncrack lightweight partition board. The adhesive comprises the following components in parts by mass: 10-20 parts of alumite, 5-12 parts of mica powder, 15-20 parts of guar gum, 3-7 parts of propylene glycol alginate, 8-13 parts of India gum, 10-15 parts of silicon dioxide, 5-12 parts of calcium oxide, 2-8 parts of reinforcing fiber, 8-12 parts of cement, 4-9 parts of calcium lignosulfonate, 2-4 parts of a water retaining agent, 20-30 parts of silica sol, and 12-25 parts of river sand. The adopted raw materials are simple and easy to obtain, the preparation method gradually changes, the prepared adhesive has very good shrinkage resistance, a joint of the partition board cannot be layered, crack and bulge after the use of the adhesive, and the durability is improved; and the components of the adhesive provided by the invention do not contain toxic and harmful substances, so that the adhesive completely meets requirements of environmental protection, is safe and pollution-free, is good in high temperature resistance and fire resistance, and can resit fire for 2h without burning.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environmental-friendly adhesive for dry-cracking and anti-cracking 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 ...
