Embodiment 1

[0043] A cement-based glaze caulking agent, the production process of which is: spray 4 parts of 30% carnauba wax emulsion into 38 parts of 1250-mesh superfine calcite powder, mix them evenly, and bake in an oven at 50-60°C for 24 hours , after cooling to room temperature, add 8 parts of powdered sodium silicate, 0.8 parts of sodium hexafluorosilicate, 0.16 parts of 200000mPa.s HPMC, 0.15 parts of P803, 0.1 part of iron red, stir well, then add 35 parts of P.032.5 white silicon Salt cement, 14 parts of 1250 mesh superfine precipitated barium sulfate, 13.9 parts of 1250 mesh lime calcium powder, and continue to stir until the pigments and fillers are evenly dispersed to obtain a pink cement-based glaze caulking agent.

Embodiment 2

[0045] A cement-based glaze caulking agent, the production process of which is as follows: spray 2 parts of 35% carnauba wax emulsion into 33 parts of 1250 mesh superfine calcite powder, mix evenly, and bake in an oven at 50-60 °C for 24 hours , after cooling to room temperature, add 9 parts of powdered sodium silicate, 0.8 parts of magnesium phosphate, 0.2 parts of 100000mPa.s HEC, 0.2 parts of AP 199, 0.5 parts of iron black, after stirring evenly, add 30 parts of P.042.5 ordinary silicate Cement, 12.3 parts of 1250 mesh superfine precipitated barium sulfate, 12 parts of 1250 mesh lime calcium powder, and continue to stir until the pigments and fillers are evenly dispersed to obtain a black cement-based glaze caulking agent.

Embodiment 3

[0047] A cement-based glaze caulking agent, the production process of which is as follows: spray 2.5 parts of 32% carnauba wax emulsion into 35 parts of 1250 mesh superfine calcite powder, mix evenly, and bake in an oven at 50-60°C for 24 hours , after cooling to room temperature, add 7 parts of powdered sodium silicate, 0.7 parts of sodium hexafluorosilicate, 0.14 parts of 200000mPa.s HPMC, 0.2 parts of P803, after stirring evenly, add 42 parts of P. 1250 mesh ultrafine precipitated barium sulfate, 12.3 parts of 1250 mesh lime calcium powder, and continue to stir until the pigments and fillers are evenly dispersed to obtain a white cement-based glaze caulking agent.

Abstract

The invention discloses a cement-based glaze caulking agent and a preparation method thereof, comprising the following components and their weight percentages: 30-40% of cement, 10-20% of precipitated barium sulfate, 10-20% of lime calcium powder, and calcite Powder 30-40%, water glass powder 5-10%, curing agent 0.5-1%, brightening agent 2-4%, cellulose 0.1-0.2%, defoamer 0.1-0.2%, pigment and filler 0-0.5%. The test results show that the cement-based glaze caulking agent of the present invention meets the standard requirements of JC / T1004-2006 "Ceramic Wall and Floor Tile Sealing Agent", the glossiness Gs(60) reaches about 15, and the Gs(20) reaches about 3.3.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a cement-based glaze caulking agent and a preparation method thereof. Background technique [0002] Caulking agent, also known as caulking agent, is generally made of polymer materials and base materials, and is mainly used for hooking and embedding of various stone joints such as glazed tiles, marble, and granite. It has very good cohesiveness, which can make the joints without cracks, so as to prevent moisture and rainwater from penetrating into the wall, especially in winter when the water infiltrated into the joints freezes and causes the pasted bricks to fall off. At the same time, it can also reduce the precipitation of free calcium in the cement mortar, so that the paste surface remains beautiful. According to JC / T1004-2006 "Ceramic Wall and Floor Tile Joint Filler" industry standard, joint sealants are divided into cement-based joint sealants and r...
