Abstract

The invention discloses a preparation method of a building caulking agent. The method specifically comprises the following steps: mixing spherical graphite, hexadecyl trimethyl ammonium chloride and an ethanol solution, adjusting the temperature to 60-80 DEG C, stirring for 40-50min, carrying out filtration and washing, adjusting the water content to 70-80%, adding a graphene oxide aqueous dispersion in a stirring state, and continuing to carry out stirring, filtration and washing, and carrying out drying; adding epoxy resin into a product, heating the epoxy resin in a stirring state until theepoxy resin is in a molten state, and continuing to carry out stirring to obtain pretreated epoxy resin; and stirring the pretreated epoxy resin, acrylate rubber, alkyd resin and hydroxypropyl cellulose, cooling, adding pigment, a delustering agent, river sand, Portland cement, a leveling agent and an antifoaming agent, and continuing to carry out stirring to obtain the building caulking agent. The prepared building caulking agent is good in binding power, the binding position is not prone to opening, and the impermeability and the water resistance of the building caulking agent are excellent.

Description

technical field [0001] The invention relates to a caulking agent, in particular to a building caulking agent which has good cohesive force, is difficult to open at the joint, and has excellent impermeability and water resistance and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] The caulking agent is a kind of gray powder prepared from polymer materials and base materials. It is mainly used for hooking and embedding of various stone seams such as glazed tiles, marble, and granite. The caulking agent has a good Excellent cohesiveness, which can make the embedded road without cracks, so as to prevent moisture and rainwater from penetrating into the wall, especially in winter, the water infiltrated into the seam will cause the pasted brick to fall off after freezing, and at the same time, it can also reduce cement. The precipitation of free calcium in the river mortar keeps the paste surface beautiful. [000...
