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.

Embodiment 1

[0032] Embodiment 1 (preparation with honeycomb glass beads):

[0033] First, crush the pure glass products recovered from industrial or civil use into glass powder of about 380 mesh, add calcium carbonate powder and water glass diluent to the glass powder (water glass and water are mixed in a ratio of 4:1), The addition of calcium carbonate powder is 5% of the weight of the glass powder, and the addition of water glass diluent is added in an amount of 0.18 liters per kilogram of glass powder. The three are mixed evenly, and then the mixture is sent to the rotary kiln. , making it melt, expand and then cool at a high temperature of 810°C to obtain spherical particles with rough surfaces. These particles are sieved through 35 mesh, 50 mesh and 60 mesh sieve buckets to obtain particle sizes of 0.1-0.3mm, 0.25-0.5 mm glass beads with a honeycomb network structure inside, such as figure 1 , 2 As shown, the measured bulk density of the glass beads is 420kg / m 3 , The cylinder com...

[0035] 1. Formula

[0036] 2,

[0037] 3. Preparation and testing

[0038] Mix the components of the above 1# formula evenly, add water with a weight of 49% of the material, mix the components of the 2# formula evenly, add water with a weight of 52%, respectively, according to the standard JC / T547-2005 "Ceramic Wall and Floor Tile Adhesive" Stir with the stirring equipment and stirring method specified in , and then test according to this standard, the performance is as follows:

[0039]

[0040] It can be seen from the above table that the tile adhesive of the present invention can meet the performance index of C2TES1. In addition, the wet density of ordinary tile adhesives is mostly 1500kg / m 3 Above, and the wet density of the present invention is 1200kg / m 3 about. The tile adhesive of the present invention has a reasonable formula, and the introduction of hon...

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 ...
