specific Embodiment

[0021] The present invention and specific embodiment are described in the following:

[0022] chemical composition

SiO 2

Fe 2 o 3

CaO

Al 2 o 3

MgO

Mass percentage (%)

53.63

6.82

6.75

27.00

1.46

[0023] Fineness (residue of 45um square hole sieve): 14%

[0024] Loss on ignition: 4.74%

[0025] Water demand ratio: 98%

[0026] SO 3 Content: 2.23%

[0027] Moisture content: 0.5%

[0028] The present invention is example with preparing 1000 kilograms of dry powder tile adhesives:

[0029] Get 800 kg of secondary fly ash, add it to a specific stirring tank, add 75 kg of activator, 110 kg of Portland cement (mark 42.5), 10 kg of latex powder (fineness is 200 mesh butadiene-styrene Polymer), 4 kg of cellulose ether and 1 kg of defoamer, stirred in a stirring tank for half an hour, after uniform mixing, the dry powder tile adhesive can be obtained.

Embodiment 2

[0030] Embodiment 2: The chemical composition and index of the fly ash utilized in this embodiment are the same as those of the above-mentioned examples. Take the preparation of 1000 kg of dry powder tile adhesive as an example: get 700 kg of fly ash, add it to the stirring tank, and then Add 100 kilograms of calcium sulfate and calcium oxide (weight ratio is 2: 1) mixture, 175 kilograms of Portland cement (marked as 42.5), 20 kilograms of latex powder (fineness is 200 mesh butadiene-styrene polymer) , 4 kg of cellulose ether and 1 kg of defoamer, stirred in a stirring tank for half an hour, so that after uniform mixing, you can get dry powder tile adhesive.

[0031] When using, according to the construction requirements, a certain proportion of water can be added, that is, the dry powder tile adhesive and water are mixed in a ratio of 2:1, and after stirring evenly, it can be used after standing for 10 minutes.

Abstract

The invention relates to a ceramic tile special binder adopting powder coal as main raw material, namely a dry powder ceramic tile binder, its components (wt%): secondary powder coal 60-90%, exciter 3-10%, cement 6-20%, emulsion powder 1-5%, water-retaining agent 0.2-1.0% and defoaming agent 0.05-0.15%. It weighs its components to place in stirring kettle, and uniformly stirs for a period of time to obtain the dry powder ceramic tile binder at once. When used, it is added in a certain proportion of water and uniformly stirred to be used at once. It has better construction property and adhesion or adhesive strength. It develops a new way of synthetical utilization of powder coal.

Description

technical field [0001] The invention relates to a dry powder adhesive for tiles, more specifically, a special adhesive for tiles with fly ash as the main raw material, belonging to the technical field of chemical building materials. Background technique [0002] At present, in the construction and decoration industry, as adhesives for tile paving of building materials, polyvinyl acetal glue plus cement, polymer emulsion with filler, water glass with filler, and polymer materials and Modified powdered product based on cement. Above these ceramic tile adhesives, its raw material cost price is more expensive, should not be widely used, and also unfavorable to environmental protection. Contents of the invention [0003] The purpose of the present invention is to provide a ceramic tile adhesive with fly ash as the main raw material, and open up a new way for the comprehensive utilization of fly ash. [0004] The present invention adopts the following technical solutions to ac...
