Embodiment 1

[0032] A joint filler includes cement-based base material and modified material, the modified material includes porous microspheres, and binder is pre-absorbed inside the porous microspheres. For the specific limitations of the above-mentioned cement-based base material, porous microspheres and binder, please refer to the preparation method of the following joint filler.

[0033] The preparation method of above-mentioned caulking agent comprises the following steps:

[0034] (1) Dissolve the binder sodium carboxymethyl cellulose in water evenly at room temperature.

[0035] (2) Mix mullite balls with a porosity of 60%, an outer diameter of 40 μm and a porosity of 75%, and an outer diameter of 600 μm, according to a weight ratio of 2:3 and place them under negative pressure conditions. The binder pumped into the pores of the mullite ball, when the amount of binder entering the mullite ball changes little, stop the pumping, and cure for 8 hours in a curing box with a humidity o...

Abstract

The invention discloses a joint mixture which comprises a cement-based base material and a modified material located in the cement-based base material, the modified material is a porous microsphere, and a binder is sucked into the porous microsphere in advance. The invention also provides a preparation method of the joint mixture. The joint mixture disclosed by the invention comprises the porous microspheres into which the binder is sucked in advance, and the binder in the porous microspheres can be released outwards along with the increase of the water content in the joint mixture, so that the bonding performance between the joint mixture and doors and windows is improved, and the joint mixture disclosed by the invention has the advantages of excellent bonding performance, no cracking and excellent mechanical strength; the device is especially suitable for high-temperature and high-humidity environments.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a caulking agent and a preparation method thereof. Background technique [0002] Water seepage and water leakage of building doors and windows is one of the most common problems in the construction field, especially for building doors and windows in areas with a lot of rain, high temperature and high humidity. Once the water leaks in the rainy season, it is difficult to squeeze out time to repair it. At the same time, it takes a lot of money and time to repair the building leakage. These problems make the residents and merchants physically and mentally exhausted; Area flaking and mold also affect the health of residents and businesses. [0003] One of the most important reasons for water seepage and water leakage of building doors and windows is that the performance of the door and window caulking materials is not good, and it is easy to seep and leak water through the caulking...
