Preparation method of flashing compound for tile

Abstract

The invention provides a preparation method of a waterproof and weather-resistant flashing compound special for filling slits between tiles. The flashing compound comprises components by weight of 25-35% of portland cement, 50-68% of quartz sand (70-110 mesh), 5-10% of bauxite cement, 1.5-2% of redispersible emulsion powder, 1-2% of cellulose ether, 0.3-0.6% of powder antifoaming agent, 0.3-0.6% of powder water repellent and 0.3-0.6% of high efficiency water reducing agent. Compared with a flashing compound of a prior art, the flashing compound of the invention has characteristics of wide construction range, strong adhesive force, water resistance, and weather resistance, and can be widely used in slit filling of tiles and other construction materials; therefore, the flashing compound has promising popularization and application values.

Description

1. Technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of a ceramic tile waterproof caulking agent. 2. Background technology [0002] Ceramic tiles have become the main building materials in modern buildings and are widely used in the decoration of the interior and exterior walls and floors of buildings. Ordinary buildings use cement fine sand and water to make cement mortar and use it as a joint sealant. The common shortcomings of this kind of joint sealant mixed with ordinary cement and water in construction are low adhesion, fast hardening time, and short-term use. If it is not finished, the sealant will fail, which will cause the sealant to weather and fall off under the influence of natural environmental factors such as wind, sun, and rain soon after the decoration construction is completed, causing rainwater to seep into the gap between the tile and the wall In the meantime, the a...

[0002] Ceramic tiles have become the main building materials in modern buildings and are widely used in the decoration of the interior and exterior walls and floors of buildings. Ordinary buildings use cement fine sand and water to make cement mortar and use it as a joint sealant. The common shortcomings of this kind of joint sealant mixed with ordinary cement and water in construction are low adhesion, fast hardening time, and short-term use. If it is not finished, the sealant will fail, which will cause the sealant to weather and fall off under the influence of natural environmental factors such as wind, sun, and rain soon after the decoration construction is completed, causing rainwater to seep into the gap between the tile and the wall During the time, the adhesive loses its adhesion and the tiles fall off

In addition, this type of caulking agent has a high water absorption rate, and the rainwater seeps in to form soluble salts that flow out with the rainwater to produce "white pulp", which seriously pollutes the wall surface

This not only seriously affects the quality of construction and the appearance of decoration, but also the natural fall of tiles from high places will cause potential harm at any time
