Definitions
- This invention relates to a mixture composition useful in dry tile cement mortar compositions for installing ceramic tiles on walls and floors.
- This invention also relates to a dry tile cement mortar using an improved water retention agent that is prepared from raw cotton linters.
- the physical characteristics of a hardened traditional mortar are strongly influenced by its hydration process, and thus, by the rate of water removal therefrom during the setting operation. Any influence, which affects these parameters by increasing the rate of water removal or by diminishing the water concentration in the mortar at the onset of the setting reaction, can cause a deterioration of the physical properties of the mortar.
- Most ceramic tiles, on their unglazed surfaces, are highly porous and can remove a significant amount of water from the mortar leading to the difficulties just mentioned.
- most substrates to which these tiles are applied such as lime sandstone, cinderblock, wood or masonry, are also porous and lead to the same problems.
- German publication 4,034,709 A1 discloses the use of raw cotton linters to prepare cellulose ethers as additives to cement based hydraulic mortars or concrete compositions.
- CEs Cellulose ethers
- Thege CEs are capable of increasing viscosity of aqueous media.
- the viscosifying ability of a CE is primarily controlled by its molecular weight, chemical substituents attached to it, and conformational characteristics of the polymer chain.
- CEs are used in many applications, such as construction, paints, food, personal care, pharmaceuticals, adhesives, detergents/cleaning products, oilfield, paper industry, ceramics, polymerization processes, leather industry, and textile.
- Methylcellulose (MC), methylhydroxyethylcellulose (MHEC), ethylhydroxyethylcellulose (EHEC), methylhydroxypropylcellulose (MHPC), hydroxyethylcellulose (HEC), hydrophobically modified hydroxyethylcellulose (HMHEC) either alone or in combination are widely used for dry mortar formulations in the construction industry.
- a dry mortar formulation is meant a blend of gypsum, cement, and/or lime as the inorganic binder used either alone or in combination with aggregates (e.g., silica and/or carbonate sand / powder), and additives.
- these dry mortars are mixed with water and applied as wet materials.
- water-soluble polymers that give high viscosity upon dissolution in water are required.
- desired mortar properties such as high water retention (and consequently a defined control of water content) are achieved. Additionally, an improved workability and satisfactory adhesion of the resulting material can be observed. Since an increase in CE solution viscosity results in improved water retention capability and adhesion, high molecular weight CEs providing high solution viscosity are desirable in order to work more efficiently and cost effectively. In order to achieve high solution viscosity, the starting cellulose ether has to be selected carefully.
- a water retention agent that provides a 2 % aqueous solution Brookfield viscosity of preferably greater than about 80,000 mPas and still be cost effective for use as a thickener and/or water retention agent.
- the present invention relates to a mixture composition for use in a dry mortar tile cement composition of a cellulose ether in an amount of 20 to 99.9 wt % of alkylhydroxyalkylcelluloses and hydroxyalkylcelluloses and mixtures thereof, prepared from raw cotton linters, and at least one additive in an amount of 0.1 to 80 wt % of organic or inorganic thickening agents, anti-sag agents, air entraining agents, wetting agents, defoamers, superplasticizers, dispersants, calcium-complexing agents, retarders, accelerators, water repellants, redispersible powders, biopolymers, and fibres; the mixture composition, when used in a dry tile cement formulation and mixed with a sufficient amount of water, the tile cement formulation produces a mortar which can be applied to substrates wherein the amount of the mixture in the mortar is significantly reduced while correction time, applicability, and sag-resistance of the wet mortar are comparable or improved
- the present invention is also directed to a dry tile cement mortar composition of hydraulic cement, fine aggregate material, and a water-retaining agent of at least one cellulose ether prepared from raw cotton linters; the dry tile cement mortar composition, when mixed with a sufficient amount of water, produces a mortar which can be applied in thin layers for setting tile on substrates wherein the amount of the water retention agent in the mortar is significantly reduced while correction time, applicability, and sag-resistance of the mortar are comparable or improved as compared to when using conventional similar cellulose ethers.
- cellulose ethers of alkylhydroxyalkylcelluloses and hydroxyalkylcelluloses are prepared from cut or uncut raw cotton linters.
- the alkyl group of the alkylhydroxyalkylcelluloses has 1 to 24 carbons atoms and the hydroxyalkyl group has 2 to 4 carbon atoms.
- the hydroxyalkyl group of the hydroxyalkylcelluloses has 2 to 4 carbon atoms.
- alkylhydroxyalkylcelluloses and hydroxyalkylcelluloses such as methylhydroxyethylcelluloses, methylhydroxypropylcelluloses, hydroxyethylcelluloses, and hydrophobically modified hydroxyethylcelluloses, prepared from RCL give significant body and improved sag-resistance to mortars. Since mortars prepared using these RCL based CEs have improved ability to retain water, they provide longer correction times, even at reduced CE use levels. Moreover, these RCL based CEs in mortars showed a lubricating effect that positively influences applicability with the notched trowel. The use of these RCL based CEs in mortars reduces surface tension and increases amount of the make-up water required. Consequently, it is easy to mix the dry-mortar tile cement product with water.
- the mixture composition has an amount of the cellulose ether of 20 to 99.9 wt %, preferably 70 to 99.0 wt %.
- the RCL based, nonionic CEs of the present invention include (as primary CEs), particularly, alkylhydroxyalkylcelluloses and hydroxyalkylcelluloses made from raw cotton linters (RCL).
- examples of such derivatives include methylhydroxyethylcelluloses (MHEC), methylhydroxypropylcelluloses (MHPC), methylethylhydroxyethylcelluloses (MEHEC), ethylhydroxyethylcelluloses (EHEC), hydrophobically modified ethylhydroxyethylcelluloses (HMEHEC), hydroxyethylcelluloses (HEC), hydrophobically modified hydroxyethylcelluloses (HMHEC), and mixtures thereof.
- MHEC methylhydroxyethylcelluloses
- MHPC methylhydroxypropylcelluloses
- MEHEC methylethylhydroxyethylcelluloses
- EHEC ethylhydroxyethylcelluloses
- HMEHEC hydrophobically modified
- the hydrophobic substituent can have 1 to 25 carbon atoms. Depending on their chemical composition, they can have a methyl or ethyl degree of substitution (DS>of 0.5 to 2.5, a hydroxyalkyl molar substitution (HA-MS) of about 0.01 to 6, and a hydrophobic substituent molar substitution (HS-MS) of about 0.01 to 0.5 per anhydrogiucose unit. More particularly, the present invention relates to the use of these water-soluble, nonionic CEs as efficient thickener and/or water retention agents in dry-mortar tile cement applications. In practicing the present invention, conventional CEs made from purified cotton linters and wood pulps (secondary CEs) can be used in combination with RCL based CEs.
- secondary CEs can be used in combination with RCL based CEs.
- Examples of the secondary CEs are methylcellulose (MC), methylhydroxyethylcellulose (MHEC), methylhydroxypropylcellulose (MHPC), hydroxyethylcellulose (HEC), ethylhydroxyethylcellulose (EHEC), hydrophobically modified hydroxyethylcellulose (HMHEC), hydrophobically modified ethylhydroxyethylcellulose (HMEHEC), methylethylhydroxyethylcellulose (MEHEC) , sulfoethyl methylhydroxyethylcelluloses (SEMHEC), sulfoethyl methylhydroxypropylcelluloses (SEMHPC), and sulfoethyl hydroxyethylcelluloses (SEHEC).

- cellulose ethers are prepared according to US Patent Application Serial No. 10/822,926, filed April 13, 2004, which is herein incorporated by reference.
- the starting material of this embodiment of the present invention is a mass of unpurified raw cotton linter fibers that has a bulk density of at least 8 grams per 100 ml. At least 50 wt % of the fibers in this mass have an average length that passes through a US sieve screen size number 10 (2 mm openings).
- This mass of unpurified raw cotton linters is prepared by obtaining a loose mass of first cut, second cut, third cut and/or mill run unpurified, natural, raw cotton linters or mixtures thereof containing at least 60 % cellulose as measured by AOCS (American Oil Chemists' Society) Official Method Bb 3-47 and comminuting the loose mass to a length wherein at least 50 wt % of the fibers pass through a US standard sieve size no. 10.
- the cellulose ether derivatives are prepared using the above- mentioned comminuted mass of raw cotton linter fibers as the starting material.
- the cut mass of raw cotton linters is first treated with a base in a slurry or high solids process at a cellulose concentration of greater than 9 wt % to form an activated cellulose slurry. Then, the activated cellulose slurry is reacted for a sufficient time and at a sufficient temperature with an etherifying agent or a mixture of etherifying agents to form the cellulose ether derivative, which is then recovered.
- an etherifying agent or a mixture of etherifying agents to form the cellulose ether derivative, which is then recovered.
- the CEs of this invention can also be prepared from uncut raw cotton linters that are obtained in bales of the RCL that are either first, second, third cut, and/or mill run from the manufacturer.
- Raw cotton linters including compositions resulting from mechanical cleaning of raw cotton linters, which are substantially free of non- cellulosic foreign matter, such as field trash, debris, seed hulls, etc., can also be used to prepare cellulose ethers of the present invention.
- Mechanical cleaning techniques of raw cotton linters including those involving beating, screening, and air separation techniques, are well known to those skilled in the art. Using a combination of mechanical beating techniques and air separation techniques fibers are separated from debris by taking advantages of the density difference between fibers and debris.
- a mixture of mechanically cleaned raw cotton linters and "as is" raw cotton linters can also be used to manufacture cellulose ethers.
- the performance of the mortars of this invention are improved with regard to correction time, applicability, and sag- resistance. These are important parameters used widely in the art to characterize the performance of tile cement mortars.
- Core time is defined as the time during which the position of the tile on the wall can be changed without the tile coming loose from the mortar.
- Applicability is defined as the ease of applying the tile cement to a substrate, such as floor or wall surfaces. Applicability is rated subjectively by the craftsman, and is a description of how easy it is to spread the mortar onto the substrate.
- Sag-resistance is the ability of a vertically applied tile cement to fix a tile in position where it was embedded into the mortar bed so that the tile does not slide down.
- a typical dry tile cement mortar might contain some or all of the following components:
- Example 1 Examples 1 and 2 show some of the chemical and physical properties of the polymers of the instant invention as compared to similar commercial polymers. Determination of substitution Cellulose ethers were subjected to a modified Zeisel ether cleavage at 150° C with hydriodic acid. The resulting volatile reaction products were determined quantitatively with a gas chromatograph.
- Viscosities of currently available, commercial methylhydroxyalkylcelluloses, which are based on purified cotton linters or high viscous wood pulps have maximum 2 wt % aqueous solution viscosity of about 70,000 to 80,000 mPas (as measured using Brookfield RVT viscometer at 20°C and 20 rpm, using a spindle number 7).
- Sodium chloride content The sodium chloride content was determined by the Mohr method. 0.5 g of the product was weighed on an analytical balance and was dissolved in 150 ml of distilled water. 1 ml of 15% HNO 3 was then added after 30 minutes of stirring. Afterwards, the solution was titrated with normalized silver nitrate (AgN0 3 ) solution using a commercially available apparatus.
- Determination of moisture The moisture content of the sample was measured using a commercially available moisture balance at 105°C. The moisture content was the quotient from the weight loss and the starting weight, and is expressed in percent.
- Determination of surface tension The surface tensions of the aqueous cellulose ether solutions were measured at 20° C and a concentration of 0.1 wt % using a Kr ⁇ ss Digital- Tensiometer K10. For determination of surface tension the so-called "Wilhelmy Plate Method" was used, where a thin plate is lowered to the surface of the liquid and the downward force directed to the plate is measured.
- Table 1 shows the analytical data of a methylhydroxyethylcellulose and a methylhydroxypropylcellulose derived from RCL. The results clearly indicate that these products have significantly higher viscosities than current, commercially available high viscous types. At a concentration of 2 wt %, viscosities of about 100,000 mPas were found. Because of their extremely high values, it was more reliable and easier to measure viscosities of 1 wt % aqueous solutions. At this x concentration, commercially available high viscous methylhydroxyethylcelluloses and methylhydroxypropylcelluloses showed viscosities in the range of 7300 to about 9000 mPas (see Table 1). The measured values for the products based on raw cotton linters were significantly higher than the commercial materials. Moreover, the data in Table 1 clearly indicate that the cellulose ethers which are based on raw cotton linters have lower surface tensions than the control samples.
- Example 2 Determination of substitution Cellulose ethers were subjected to a modified Zeisel ether cleavage at 150°C with hydriodic acid. The resulting volatile reaction products were determined quantitatively with a gas chromatograph.
- Hydroxyethylcelluloses were made from purified as well as raw cotton linters in Hercules' pilot plant reactor. As indicated in Table 2, both samples have about the same hydroxyethoxyl-content. But viscosity of the resulting HEC based on RCL is about 23% higher.
- Example 3 All tests were conducted in tile cement of 30.00 wt % Portland cement (CEM I 42,5 R), 69.70 wt % silica sand (0.1 - 0.3 mm in diameter), and 0.30 wt % of cellulose ether.
- the capability of the mortar to keep the water enclosed for a certain time period was expressed in the correction time or also called adjustability.
- the mortar was applied on a lime sandstone brick and several tiles were embedded by hand.
- the adjustability was checked every few minutes by turning one of the tiles by a slight angle in both directions with low power. With loss of water the consistency of the mortar bed increased until turning of the tile leads to loss of adhesion.
- MHEC Methylhydroxyethylcellulose
- MHPC methylhydroxypropylcellulose
- RCL-MHEC based tile cement showed an improvement in open time as compared to the control MHEC at both "typical" and reduced addition levels. This effect might results from the higher water ratio of this sample. Nevertheless, sag-resistance of the resulting mortar was slightly improved.
- Example 4 All tests were conducted in tile cement of 30.00 wt % Portland cement (CEM I 42,5 R), 69.70 wt % silica sand (0.1 - 0.3 mm in diameter), and 0,30 wt % of cellulose ether. Water demand of the samples was adjusted to achieve comparable (550,000 ⁇ 50,000 mPas) consistency.
- MHEC methylhydroxyethylcellulose
- MHPC methylhydroxypropylcellulose
- the polyacrylamide (PAA) used had a molecular weight of 8 to 15 million g/mol, a density of 825 ⁇ 50 g/dm 3 ; and an anionic charge of 15-50 wt %.
- the hydroxypropyl starch (STE) had a hydroxypropoxyl-content of 10-35 wt %, a bulk density of 350-550 g/dm 3 , a moisture content as packed of max. 8 wt %, particle size (Alpine air sifter) of max. 20 wt % residue on 0.4 mm sieve, and a solution viscosity (at 10 wt %, Brookfield RVT, 20 rpm, 20°C) of 1500-3000 mPas.
- These additives (PAA and STE) were tested in the above-mentioned tile cement composition in comparison to modified, high viscosity MHEC and MHPC, respectively, as control samples which were blended accordingly. The results are shown in Table 4.
- modified RCL-CE based tile cements To achieve the target consistency of 550,000 (+ 50,000) mPas, the water demand for the modified RCL-CE based tile cements was higher than that of commercially available modified methylhydroxyalkylcellulose based tile cements (controls). Even at reduced use level (0.27 w t% instead of 0.30 wt %) water factor of the RCL-CEs was still higher, i.e. the RCL-based samples had a stronger thickening effect. At the reduced dosage level, modified RCL-CE based tile cements showed open times, which were at least comparable to the corresponding control samples at both "typical" and reduced addition levels.
- modified RCL- MHEC or MHPC performed comparable or better than the corresponding control samples, which were tested at "typical" dosage.
- Example 5 All tests were conducted in tile cement of 30.00 wt % Portland cement (CEM I 42,5 R), 69.75 wt % silica sand (0.1 - 0.3 mm in diameter), and 0.25 wt % of cellulose ether.
- Mortar viscosity, open time and correction time were determined, as described in Example 3.
- HEC made from RCL was compared to HEC made from purified linters as control with respect to application performance in tile cement. The results are shown in Table 5.
