Problems solved by technology

However, this method requires protein (such as bovine serum albumin) and protease, and the cost is extremely high, which is not conducive to industrialization. It can be seen from its examples that if no pretreatment hydrogel (Example 2) or no added degraded protein Modified zeolite (Example 3), tile grouting agent has significantly reduced pan-alkaline resistance and reduced strength

Abstract

The invention belongs to the technical field of building materials, and discloses a preparation method of a building tile joint filler. The preparation method of the building tile joint filler of the present invention comprises: (1) dissolving polyvinyl alcohol in ethanol aqueous solution, and then adding water-soluble resin liquid to obtain polyvinyl alcohol glue; (2) pulverizing natural zeolite, heat preservation and heat treatment to obtain Pretreatment zeolite; (3) Add alkali solution to ethanol aqueous solution of ethyl orthosilicate, control pH to 8‑10, then add lithium nitrate, stir and react, and mix the obtained solution with pretreatment zeolite to obtain modified zeolite; (4 ) Mix graphite with oxidant and stir to react to obtain graphite oxide; (5) Take cement, quartz sand, pigment, polyvinyl alcohol glue, modified zeolite and graphite oxide, stir and mix, then add water, and stir to obtain tile joint sealant . The method is suitable for large-scale industrial application, the process is simple, the cost is low, and it is easy to popularize, and the prepared ceramic tile grout has excellent mechanical properties and good pan-alkali resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of building tile grout. Background technique [0002] A kind of acid and alkali resistant porcelain or stone building or decorative material is called ceramic tile, which is formed by grinding, mixing, pressing, glazing and sintering with refractory metal oxides and semi-metal oxides. It is mostly made of clay, quartz sand, compressed after high temperature, etc., and has high hardness. In tile laying, it is essential to fill the gaps between bricks. Using tile grout to caulk the seams can ensure that there are no cracks in the seams, and has good anti-seepage performance. Prevent moisture and rainwater from penetrating into the wall, especially in winter, when the water infiltrated into the seams freezes and expands, causing the pasted bricks to fall off and affect the appearance. [0003] The traditional tile grout is made of cement as the main...
