Abstract
A tile gap filling mortar comprises a base material and an additive, and the base material comprises, by weight, 370-420 parts of ordinary Portland cement, 520-580 parts of sand and 40-50 parts of heavy calcium powder; and the additive comprises, by weight, 2-3 parts of high-molecular xanthan gum powder, 0.25-0.75 parts of hydroxypropyl methyl cellulose, 5-10 parts of re-dispersible latex powder, 1-2 parts of a water repellent, 1-3 parts of glass water and 1-5 parts of a water reducer. The increase of the additive improves the water retention and the bonding force of the mortar, reduces the shrinkage of the mortar and increases the ageing resistance of the mortar, so the mortar can effectively fill gaps between tiles, and slit cracking is avoided. The addition of the water glass makes the adhesion stress and the acid and alkali resistance of the mortar enhanced. The addition of the water repellent enhances the corrosion resistance of the gap filling mortar to make a permanent waterproof film formed.
Description
Technical field
The invention belongs to the technical field of material of construction, be specifically related to a kind of mortar for ceramic tile joint filling.
background technology
At present, the mortar of ceramic tile joint filling be by sand, cement, hydrophober and water according to a certain percentage at the scene mix make the joint filling that simple sand-cement slurry is used for ceramic tile.Although this type of mortar adds the additives such as a small amount of hydrophober, improve the hydrophobic function of mortar to a certain extent, but the intensity that such mortar is used for joint filling is not high, gap between ceramic tile is the relatively low place of whole floor or metope intensity, easy cracking failure, cohesive force is not strong, and easily occurs accumulation of salt in the surface soil water phenomenon.
Summary of the invention
The present invention provides a kind of ceramic tile joint filling mortar to solve the problems of the technologies described above, and the invention solves the technical problems such as bonding force in prior art is not strong, easy to crack.
A kind of ceramic tile joint filling mortar, its each component and parts by weight are comprise base-material: cement 370-420 parts, 520-580 parts, sand, dicalcium powder 40-50 parts; Additive: polymer xanthan rubber powder 2-3 parts, Vltra tears 0.25-0.75 part, redispersable latex powder 5-10 parts, hydrophober 1-2 parts, bath of glass 1-3 parts.
Preferably, water reducer 1-5 parts is comprised.
Preferably, described cement 395 parts, 550 parts, sand, dicalcium powder 45 parts, polymer xanthan rubber powder 2.5 parts, Vltra tears 0.5 part, redispersable latex powder 7.5 parts, hydrophober 1.5 parts, bath of glass 2 parts, water reducer 2.5 parts.
Preferably, described cement is normal silicate 42.5 cement.
Preferably, described sand is 50-140 orders.
Get ordinary Portland cement in proportion, sand, dicalcium powder, polymer xanthan rubber powder, Vltra tears, redispersable latex powder, hydrophober, bath of glass, water reducer are admixed together, add in clear water to stirrer in the ratio of weight of material 25-30% and carry out about 20 minutes uniform stirrings, obtain the mortar that workability is good, cohesive force is strong.The invention provides a kind of ceramic tile joint filling mortar, by the increase of additive, improve water-retentivity and the bonding force of mortar, decrease the shrinking percentage of mortar, mortar is more ageing-resistant, effectively can tamp the space between ceramic tile and ceramic tile, avoid the generation of the phenomenons such as gap cracking.Adding of polymer xanthan rubber powder and Vltra tears, significantly can improve the stickiness of mortar, its Water-saving effect is good, play the effect of slow setting, the operating time of operating personnel can be extended, can be suitable for longer-distance conveying, the intensity after sclerosis is high, avoids the ceramic tile after bonding and loosens or fall.The interpolation of redispersable latex powder, enhances the water resistance of mortar, also can construct in a humidity environment.Adding of bath of glass, can the cohesive force of reinforced mortar and resistance to acids and bases.The interpolation of hydrophober, makes the erosion resistance of mortar joint filling strengthen, can form permanent waterproof membrane.
