Description

A kind of ceramic tile bond

Technical field

The present invention relates to building material field, be specifically related to a kind of ceramic tile bond.

Background technology

Ceramic tile has a wide range of applications in decorative material for wall surface, the ceramic tile bond majority applied in the market is sand-cement slurry, the shortcoming of sand-cement slurry is that cohesive force is weak, poor durability, easily peel off, when stirring at the scene, not only proportioning is unstable for the mode of thick-layer construction, and larger pollution can be caused to environment, speed of application is slow, also can cause the waste of material.For the problem existing for traditional cement mortar, people propose the ceramic tile bond of polymer modification, mix cohesive strength and non-deformability that polymkeric substance can increase substantially mortar, make it to become a kind of high-quality environment protective type polyalcohol cement basis compoiste adhering material.It with the quartz sand of the cement of high-quality, high-quality and polymer adhesive for major ingredient, add the various additives of proportion speed, through the powdery matrix material that mixing machine stirs, fundamentally solve cracking, hollowing existing in building decoration and fitment, come off and the disadvantage such as seepage, the organism added in ceramic tile bond makes binding agent have larger flexibility, the distortion produced in various environment after can compensating cement setting, ceramic tile can be avoided to come off, improve construction quality, present ceramic tile bond has been widely used in various engineering.

In developed countries such as America and Europes, nearly all ceramic tile pastes the serial tackiness agent that engineering all adopts conformance with standard JC/T547 " ceramic wall and floor bricks tackiness agent ".JC/T547 standard has carried out more than 20 year in China, but in the patch block engineering of China's reality, the glue for tile meeting this standard does not obtain a large amount of universal uses.It is reported, China still adopts Site cement sand (or scene adds some building glues) to construct close to the patch block engineering of 90%, not only labour intensity is large, construction environment is poor, and final stickup potential safety hazard is large, particularly in recent years, large size, low water absorption vitrified tile paste hollowing in engineering, the quality problems such as to come off get more and more; And, although about there is the patch block engineering of about 10% to have employed ceramic tile tackiness agent, but still exist some due to material do not mate with ceramic tile, the series of problems such as early strength is low, open assembly time is short, slippage, operating efficiency and paste security and do not obtain actual raising.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of ceramic tile binding agent, meet industry standard, makes construction safer, reliable.

The solution that the present invention solves its technical problem is: provide a kind of ceramic tile bond, composed of the following components:

Cement 30 ~ 45wt%;

70 ~ 100 order quartz sand 45 ~ 60wt%;

Redispersable latex powder 3 ~ 10wt%;

Wood fibre 0.1 ~ 0.4wt%;

Ether of cellulose 0.3 ~ 0.6 wt%;

Hardening accelerator 0.05 ~ 0.5 wt%;

Water reducer 0.1 ~ 0.2 wt%.

Described cement is No. 42.5 ordinary Portland cements.

The median size of described redispersable latex powder is 70 μm.

The length of described wood fibre is 800 ~ 2000 μm.

Described ether of cellulose is hydroxypropyl methyl cellulose ether, and viscosity is at 8000 ~ 30000mp.s.

The invention has the beneficial effects as follows: the present invention by formulation optimization, improves the anti-slipping property of ceramic tile bond, adhesive property, solve the slippage after the caducous technical problem of ceramic tile and tile paste, make construction safer, reliable, quick.

Embodiment

Below with reference to embodiment, clear, complete description is carried out to the technique effect of design of the present invention, generation, to understand object of the present invention, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present invention, instead of whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of protection of the invention.Each technical characteristic in the invention, can combination of interactions under the prerequisite of not conflicting conflict.

The invention provides a kind of ceramic tile bond, composed of the following components:

Cement 30 ~ 45wt%;

70 ~ 100 order quartz sand 45 ~ 60wt%;

Redispersable latex powder 3 ~ 10wt%;

Wood fibre 0.1 ~ 0.4wt%;

Ether of cellulose 0.3 ~ 0.6 wt%;

Hardening accelerator 0.05 ~ 0.5 wt%;

Water reducer 0.1 ~ 0.2 wt%.

Cement and quartz sand are the framework material of binding agent, and preferably, described cement is No. 42.5 ordinary Portland cements.

Redispersable latex powder is a kind of powder that can be dissolved in water; it is the multipolymer that a kind of kind is a lot; it utilizes polyvinyl alcohol to be used as protective colloid; there is extremely outstanding cohesive strength; the flexibility of binding agent can be improved and have the longer open hour; give the alkali resistance that ceramic tile bond is excellent, improve the binding property of binding agent, folding strength, water-repellancy, plasticity-, wear resisting property and application property.Preferably, the median size of described redispersable latex powder is 70 μm.

Wood fibre belongs to a kind of organic wadding fibrous material, is a kind of material of environmental protection.Good effect is had, the merit that it mainly possesses to the sticking power etc. on the adaptability prevented in coating cracking, raising water-retentivity, raising stability and construction, surface of gaining in strength, strengthen

Can have: thixotroping, protection, absorption, carrier and compound.Because the capillary action that fibrous texture has, it can be transported to pulp surface and interface fast the moisture of internal system, what contained humidity in mortar was distributed is more even, the situation of its surface skining is greatly reduced, and contemporaneously cohesive strength and surface strength increase significantly, cause the reason of this change to be in constantly dry process, tension force constantly reduces, so the enhancing gradually of its splitting resistance preferably, preferably, the length of described wood fibre is 800 ~ 2000 μm.

Methyl cellulose ether is the gelling that thermal reversibility can occur.Particularly, when the aqueous solution of this ether of cellulose is heated to the gelation temperature exceeding it, form hydrogel.This process is reversible, and namely when being cooled to lower than gelation temperature, gel is transformed into the aqueous solution in time again.The gel forming medium tenacity can improve the physical strength of bonding.Preferably, described ether of cellulose is hydroxypropyl methyl cellulose ether, and viscosity is at 8000 ~ 30000mp.s.

Hardening accelerator and water reducer can by those skilled in the art as required, be selected from the product known.

Various embodiments of the present invention adopt ingredients by weight per-cent as shown in the table:

above-mentioned various raw material is added in mixing machine in certain sequence, after fully mixing, obtains ceramic tile bond.The ceramic tile bond obtained is according to the requirements of JG547-2005 " ceramic wall and floor bricks tackiness agent " standard, and test, test result is as follows:

known by above test result, the tensile strength after the former tensile strength of binding agent of the present invention, water inlet, the tensile strength after heat-proof aging, the tensile strength after freeze-thaw cycle are all not less than 0.8MPa.

Above better embodiment of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the application's claim limited range.
