Glass bead with honeycomb holes and tile glue with glass bead

Abstract

The invention provides a glass bead with honeycomb holes, which can be used as light-weight packing in dry mixed mortar. The glass bead is prepared by crushing a pure glass product recycled industrially or civilly into glass powder of below 400 meshes, uniformly mixing the glass powder, a foaming agent and an adhesive, and then fusing, swelling, cooling and screening the mixture under the condition of high temperature of 800-820 DEG C. The glass bead is a regular spherical particle with a rough appearance and has a honeycomb meshed structure internally; the particle size is 0.1-5mm; the stacking density is 310-460kg / m<3>; and the barrel pressure intensity is 2.6-2.8MPa. The glass bead with the honeycomb holes is regular in appearance, high in compression strength and low in water absorption rate, is used as the light-weight packing in the dry mixed mortar, has the characteristics of large volume yield and the like, is easy to construct and is an ideal material which replaces expanded perlite to be used as the light-weight packing in the dry mixed mortar. The invention also provides tile glue with the honeycomb-hole glass bead. The tile glue comprises the following raw materials in percentage by weight of: 45-50% of portland cement, 15-20% of glass bead with honeycomb holes, 10-15% of heavy calcium carbonate, 10-15% of fine sand and 6-9% of additive.

Description

technical field [0001] The invention relates to a filler, in particular to a lightweight filler, and more particularly to a glass bead with honeycomb holes that can be used as a lightweight filler in dry-mixed mortar. The present invention also relates to a tile adhesive containing the honeycomb glass beads. Background technique [0002] At present, the commonly used lightweight fillers in dry-mixed mortar include expanded perlite, expanded vermiculite, ceramsite and polystyrene particles; the most widely used expanded perlite is high-quality acidic volcanic glassy rock for crushing, drying, Put it into a high-temperature roasting furnace and heat it at 1000-1300°C to make it instantly expand 4-30 times as a light-weight thermal insulation material. The expanded perlite particles are irregular, the surface is rough and angular, and there are interconnected holes inside. Its compressive strength is low, and it is easy to break during the stirring process, which makes it ...

Problems solved by technology

Although the existing ordinary tile adhesives can meet the requirements of partial tensile bond strength, in special construction occasions, if the opening time of more than 30 minutes is required, the anti-sliding and lateral deformation indicators of ordinary tile adhesives are far from reaching requirements, and in the thin-layer construction process, the application thickness of tile adhesive is only about 5mm. How to make such a small amount of tile adhesive have better performance is the subject of research by technicians in this industry.
