Description

A kind of high strength china tile adhesive and preparation method thereof

Technical field

The present invention relates to ceramic tile bond technical field, especially a kind of high strength china tile adhesive and preparation method thereof.

Background technology

The bonding material that traditional ceramic tile or stone material use, it is to use the live mortar mixed, in this mortar, Sha Heshui Mud is to be prepared at the scene, obtained cement mortar；It is to apply the cement mortar being formulated in ceramic tile bonding process The ceramic tile back side is being presoaked or pre-wetted, then the ceramic tile for scribbling mortar is being pressed onto on the surface soaked in advance, is then rapping ceramic tile To ensure that ceramic tile has consistent flatness, mortar is compacted by this process and cement granules is entered the porous back of the body of ceramic tile Inside face and in porous substrate；Realize adhesive property.

Large-scale tapestry brick stickup is carried out using the above method, such as to stone material, polished bricks, it is necessary to be mechanically fixed or Person reinforces, and after hardening of cement, the mortar in substrate is also required to reinforce, moreover, due also to above-mentioned for tile paste Traditional bonding material does not have sag resistance, so, during patch block, it is necessary to since bottom, between the tiles using positioning Device, to realize neat engagement, and this method efficiency is low, material usage is big, and needs to rely on the skilled journey of skilled worker Degree, by certain experiential operating, cause stickup result undesirable；The porosity for being additionally, since base and ceramic tile it is different, it is necessary to The immersion of certain time is carried out, and be pasted onto the amount at the ceramic tile back side to the ratio, denseness and mortar of mortar to carry out appropriately Control, otherwise will high degree the effect for influenceing ceramic tile or large-scale tapestry brick and pasting, cause easily to come off, it is difficult to protect Demonstrate,prove construction quality.

And after gypsum is combined with water, it has several minutes of beginning initial sets at normal temperatures, and final set is within 30min so that ratio The adhesives setting rate that cement is done is much faster；Although in the prior art, have researcher use desulfurated plaster be it is original, And it is aided with cement, slag micro powder, fine aggregate, latex powder, thickener etc., ceramic tile bond is configured to, realizes that industrial solid is discarded The effect of thing comprehensive utilization so that obtained ceramic tile bond all technical can reach JG/T547-2005《Ceramic wall Floor tile adhesive》Standard.

But due to incorrect to each raw material proportioning Automated generalization, raw material selection is unreasonable, causes each of ceramic tile bond Item adhesive property is still undesirable.

The content of the invention

In order to solve above-mentioned technical problem present in prior art, the present invention provide a kind of high strength china tile adhesive and Its preparation method.

It is achieved particular by following technical scheme：

It is preferred that described material composition is desulfurated plaster 20-900 parts, flyash 10-400 parts, ordinary silicon in parts by weight Acid salt cement 10-400 parts, redispersable latex powder 5-40 parts, retarder 1-3 parts.

It is preferred that described material composition is desulfurated plaster 50-800 parts, flyash 50-300 parts, ordinary silicon in parts by weight Acid salt cement 50-300 parts, redispersable latex powder 20-30 parts, retarder 1-3 parts.

It is preferred that described material composition is in parts by weight 500 parts of desulfurated plaster, 250 parts of flyash, normal silicate water 200 parts of mud, 40 parts of redispersable latex powder, 1 part of retarder.

It is preferred that described desulfurated plaster particle diameter is 130-150 mesh.

It is preferred that described Portland cement is PO42.5 Portland cements.

It is preferred that described flyash is one or two kinds of mixing in one-level flyash or second class powered coal ash.

Above-mentioned high strength china tile adhesive preparation method, comprises the following steps：

(1) raw material is weighed；

(2) raw material weighed is poured into container and mixed, and using hand blender stirring 10min, mixing speed can not Come so that material sputters；

(3) material for obtaining step (2) when in use, adds appropriate water thereto, after stirring, stands 3min, it is again stirring for, you can use.

Compared with prior art, the technique effect of the invention is embodied in：

By flyash and desulfurated plaster, Portland cement, redispersable latex powder, retarder are rationally matched somebody with somebody System so that reasonable mixture ratio, improve the adhesive property of binding agent, the adhesive strength after bonding is more excellent, and stretch-proof adhesive strength reaches To more than 1.3MPa, compression strength is in more than 12.1MPa, and rupture strength is in more than 5.2MPa.

The raw material sources of the invention are as shown in table 1 below：

Table 1

By the solid waste such as desulfurated plaster, flyash are utilized, comprehensive utilization of resources is not only realized, and Desulfurated plaster can also be caused to be acted on flyash, improve the adhesive property of binding agent, and there is good fire protecting performance, reached Temperature adjustment, damping effect are arrived.

Embodiment

Limited with reference to specific embodiment technical scheme is further, but claimed Scope is not only limited to made description.

Bonding agent preparation method in following examples, is followed the steps below：

(1) raw material is weighed；

(3) material for obtaining step (2) when in use, adds appropriate water thereto, after stirring, stands 3min, it is again stirring for, you can use.Appropriate water herein, matched and added with water with reference to bonding agent preparation of the prior art, Such as the ceramic tile bond of Patent No. 201010603926.1.

Embodiment

High strength china tile adhesive, for material composition in terms of unit of weight kg, proportioning is as shown in table 2 below：

Table 2

Experiment row

In order to fully verify technique effect that the invention has, this researcher is carried out in research process Following experiment：

Test for the first time：

1. raw material prepares

Weight is weighed as desulfurization gypsum powder 1kg, cement 0.4kg, rubber powder 0.016kg, flyash 0.5kg, retarder 0.002kg, appropriate water is added into, after being formulated according to above-mentioned preparation method.

2. test method

Preparing one group of specification is：Long 160mm × wide 40mm × high 40mm die trial box (3 die trial boxes are one group), die trial Box can be that irony can also be plastics；

After above-mentioned raw material are stirred with Handheld mixer, the die trial box for being pre-coated with one layer of releasing agent is poured into It is interior, the slurry of spilling is scraped totally, about 10mm is lifted at die trial box both ends respectively, falls it suddenly, is so vibrated 5 times respectively Struck off with flexible spatulas, be stripped after test specimen final set afterwards.

The test specimen obtained to the demoulding, according to JC/T 1025-2007《Bonding gypsum》Standard, the detection of performance indications is done, tied Fruit is as shown in table 3.

Second of experiment：

Rubber powder dosage is adjusted to 0.02kg, other are the same as the first time experiment.

Third time is tested：

Rubber powder dosage is adjusted to 0.008kg, other are the same as the first time experiment.

Table 3

Show that the increase for rubber powder volume, each Testing index can reduce by the result of table 3, so the dosage of rubber powder is not What is added is The more the better, and intensity can conversely be influenceed by having added, should be in a rational scope.

In addition, this researcher is according further to above-mentioned JC/T 1025-2007《Bonding gypsum》Standard, it is embodiment 1-16 The detection of the performance indications for the test specimen that obtained bonding agent is prepared, it is as a result as shown in table 4 below：

Table 4

By the data of table 3 show it can be seen from for the mutual effect of each material composition, be capable of the improvement of high degree The stick performance of binding agent, improve the adhesive strength of ceramic tile bond.
