Technical Field

The invention relates to the related technical field of decoration products, in particular to a preparation method of a cement-based ceramic tile joint mixture with good electrical conductivity.

Background

The cement-based ceramic tile is one of the most common ground decoration building materials, and a ground structure which is more attractive and more convenient to clean can be formed by laying the floor tiles. Currently, during tile installation, it is generally necessary to leave voids between adjacent tiles in consideration of the possibility of post-expansion, and these voids are usually filled with a gap filler during subsequent construction.

The static electricity is generated by the friction of the clean ground, the walking and the like, the charged ions can attract dust in the air on the surface of the ground, and the static electricity spark occurs due to the high voltage and easy discharge, so that certain influence is caused on areas with charged static electricity gathering, such as computer rooms, electronic factories, inflammable goods warehouses, electronic workshops, easily-sparking production areas, gas stations, military supplies or explosive factories, hangars, textiles, paper pulp, printing factories and the like, even explosion and fire are generated, and the consequence is extremely serious.

The cement-based ceramic tile joint mixture on the market at present consists of a hydraulic cementing material, mineral aggregates, organic and inorganic additives. The hydraulic cementing material is mostly portland cement, and the mineral aggregate is graded natural sand or machine-made sand, and then is mixed with the additive to prepare the hydraulic cementing material. The prepared cement-based ceramic tile gap filler has low conductivity, and in the face of the appearance of anti-static ceramic tile floors and new ceramic anti-static floors with increasingly changed markets, the ceramic tile gap filler with excellent conductivity, which is suitable for being matched with the anti-static ceramic floors, is urgently needed.

In view of the above, we propose a preparation method of a cement-based ceramic tile joint mixture with good electrical conductivity.
