Problems solved by technology

However, this kind of insulation material is generally an organic polymer foam material. The traditional process is to use polymer bonding mortar to bond the foam insulation board to the wall. This process is only suitable for low-rise buildings. After reaching a certain height, According to the national industry standard, it must be fixed with a certain number of nylon expansion nails
This method can prevent the insulation material from falling off in a short time, but it cannot stand the test of time
One of the reasons is that the texture of the thermal insulation material is loose, and the ability to hold the expansion nail is poor. After a long time, gaps will be formed and the ability to hold it will be completely lost; the second reason is that the expansion nail itself will gradually lose its grip over time. damaged and useless
Another disadvantage of using expansion nails is that it forms protrusions on the surface of the insulation material, which affects the construction and construction quality of the next process.

Abstract

The early setting anchoring mortar consists of cement 20-35 weight portions, quartz sand 35-50 weight portions, latex powder adhesive 2-5 weight portions, waterproof latex powder adhesive 1-2 weight portions, methyl cellulose 0.1-0.8 weight portion, heavy calcium carbonate 8-10 weight portions, calcium sulphoaluminate 1.5-3 weight portions, calcium chloride 0-2 weight portions, calcium sulfate 0-3 weight portions, early strength air entraining agent 0-0.3 weight portion, lignin 0-0.5 weight portion, and calcium nitrite 0-1.5 weight portions except essential water. It is applied for adhering heat insulating material to wall firmly.

Description

technical field [0001] The invention relates to a building material, in particular to an early-setting anchoring mortar. Background technique [0002] With the progress of society and the improvement of people's living standards, energy consumption has also increased significantly. However, a large amount of energy currently used is non-renewable primary energy. Therefore, energy conservation has become the consensus and responsibility of the whole society. In terms of energy consumption, the air conditioners installed and used in a large number of industrial and civil buildings consume a large amount of energy every year. During the peak electricity consumption period in summer, in order to ensure the electricity consumption of residents, some enterprises even have to limit production. Affected the normal development of the national economy. Therefore, existing countries have all begun to transform the structure of buildings to increase their thermal insulation and energy...
