Abstract

A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a dry cement based plaster (or render) composition wherein the amount of the cellulose ether in the render composition is significantly reduced. When this render composition is mixed with water and applied to a substrate, the water retention and thickening and/or sag resistance of the wet plaster are comparable or improved as compared to when using conventional similar cellulose ethers.

Description

200540139 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a mixture composition which can be used in mortar (or bottom ash) composition mainly for dry cement for mortar walls. Specifically, the present invention relates to a dry cement-based mortar (or base ash) using an improved water-retaining agent made from raw cotton linters. [Previous technology] Traditional cement-based mortars are usually a mixture of cement and sand. The dry mix is mixed with water to form a mortar. These traditional mortars themselves have poor fluidity or spreadability. Therefore, the coating of these mortars is labor-intensive, especially in the summer when the moon is injured in hot weather conditions, due to the rapid evaporation or removal of water from the sand, it leads to poor or poor workability and insufficient cement hydration. use. The physical consistency of the hardened traditional mortar to its hydration process _ p / yu α greatly affects the rate at which water is removed from it during operation. Any influence of these parameters at the beginning of the sedimentation reaction by means of adding water removal rate or eliminating the water concentration in the mortar can cause the deterioration of the mortar's physical properties. Many substances such as lime sand 1, cinder blocks, wood blocks or masonry are porous and can remove significant amounts of radon from the mortar, causing the above difficulties. In order to overcome or reduce the above water consumption problem, the prior art reveals that cellulose is used as a water-retaining agent to alleviate this problem. An example of this prior art is U.S. Patent 4'5Gl'6m. * Using propylpropyl ethyl ether fiber Vegetarian

German Patent Publication No. 4,034,709 A1 discloses the use of raw cotton linters to prepare cellulose ethers as additives to cement-based hydraulic mortar or concrete compositions. Cellulose ethers (CEs) represent a type of important commercial water-soluble polymer. These CEs can increase the viscosity of aqueous media. The viscosity of this CE is mainly controlled by its molecular weight, the chemical substitutions attached, and the structural properties of the polymer chain. CEs can be used in many applications such as construction, coatings, food, personal care, pharmaceuticals, adhesives, cleaners / or cleaning products, oil fields, paper, ceramics, polymer processing, leather and textiles. Methyl cellulose (MC), methyl hydroxyethyl cellulose (MHEC), ethyl hydroxyethyl cellulose (EHEC), methyl hydroxypropyl cellulose (MHPC), and hydroxyethyl cellulose alone or in combination (HEC), hydrophobically modified hydroxyethyl cellulose (HMHEC) is widely used in dry mortar formulations for the construction industry. Dry mortar formulation means a blend of gypsum, cement and / or lime as an inorganic blend, used alone or in combination with aggregates (such as silica and / or carbonate sand / powder) and additives. Regarding the use 'These dry mortars are mixed with water and applied as a wet material. For the desired application, a water-soluble polymer that provides high viscosity when dissolved in water is required. By using MC, MHEC, MHPC, EHEC, HEC and HMHEC or a combination thereof, the desired mortar characteristics such as high water retention (thus the control of the defined water content) are achieved. In addition, it can be seen that the obtained material has improved workability and satisfactory adhesion. Since the increase in viscosity of the CE solution leads to improved water retention and viscosity 101431.doc 200540139, high molecular weight CEs are expected to operate more efficiently and cost effectively. In order to achieve the solution viscosity, care must be taken to select the starting cellulose scale. At present, by using pure cotton linter or high viscosity wood pulp, the highest 2% by weight aqueous solution viscosity of alkyl hydroxyalkyl fibers " is about 70,000-800,000 mPas ( (For example, a Brookfield RVT viscometer is used at 20.0 and 20 rpm to measure with a shaft number of 7). Water retention agents are still required in the cement mortar industry, which can be used in a cost-effective way to improve the coating and performance characteristics of cement-based mortars. In order to help ® achieve this result, it is preferred to provide a water-retaining agent that provides a Brookfield aqueous solution viscosity that is greater than about 80,000 mpas and is still cost effective as a thickener and / or water-retaining agent . [Summary of the Invention] The present invention relates to a mixture composition for a bottom ash composition having cellulose ether in an amount of 20 to 99.9% by weight of alkylhydroxyalkyl cellulose and hydroxyalkyl cellulose and mixtures thereof. Preparation of raw cotton linters and at least one additive in an amount of 0.1 to 80 weight. Selected from organic or inorganic thickeners, anti-sagging agents, air entraining agents, wetting agents, defoamers, superplasticizers, dispersants, calcium complexing agents, retarders, accelerators, drainage agents, redispersible powders , Biopolymer and fiber; mixture composition, when used in dry cement-based mortar (or bottom ash) composition and mixed with a sufficient amount of water, the cement-based mortar (or bottom ash) composition produces a mortar Mortar, which can be coated on a substrate, wherein the amount of the mixture in the mortar mortar will be significantly reduced, and the water retention and thickening and / or sag resistance of the wet mortar are compared to when using traditional similar cellulose ethers Comparable or improved. 101431.doc 200540139 The present invention also relates to a kind of ash destruction (or bottom ash) composition mainly composed of dry sand, including hydraulic water, fine aggregate materials and at least one kind of water-retaining cellulose ether prepared from raw cotton linters. Agent. A cement-based mortar (or bottom ash) composition, when mixed with sufficient water, produces a mortar mortar that can be applied to substrates such as walls, when compared to the use of traditional similar cellulose ethers Among them, the water retention and thickening and / or sag resistance of the wet mortar are comparable or improved. It was found that specific cellulose ethers made from raw cotton linters (RCL), especially alkyl hydroxyalkyl celluloses and hydroxyalkyl celluloses, were compared to traditional commercial products made from purified cotton linters or high viscosity wood pulp. Cellulose ether has an unusually high solution viscosity. The use of these cellulose ethers in cement-based mortar (bottom ash) compositions can provide several advantages (i.e., lower cost use and better coating properties) and improved properties that are currently unattainable with traditional cellulose ethers. . According to the present invention, the cellulose ethers of the present invention such as alkyl hydroxyalkyl cellulose and warp alkyl cellulose are prepared from cut or uncut raw cotton linters. The alkyl group of the alkyl group has 1 to 24 carbon atoms and the hydroxyalkyl group has 2 to 4 carbon atoms. In addition, the hydroxyalkyl group of the hydroxyalkyl cellulose has 2 to 4 slave atoms. These celluloses_ provide unexpected benefits to cement-based ash (bottom ash). Due to the extremely high viscosity of RCL-based CEs, the effective coating performance of cement-based mortar (bottom ash) can be seen. Even if the commercial level of high-viscosity commercial CEs is lower than the current level of RCL-based CEs, similar or improved coating properties to water retention can be achieved. It can also be confirmed that alkyl hydroxyalkyl cellulose and hydroxyalkyl cellulose produced by RCL, such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, 101431.doc 200540139 hydroxyethyl cellulose and hydrophobic Modified hydroxyethyl cellulose provides significant bulk to mortar mortars and improved sag resistance. According to the present invention, the mixture composition has t 1 with 11 (: 1 ^) as the main cellulose ether, and is 20 to 99% by weight, preferably M to 99.0% by weight, based on the total weight of the mixture. The RCL-based water-soluble nonionic CEs of the present invention include (as the first CEs), especially alkylhydroxyalkylcellulose and hydroxyalkylcellulose prepared from (RCL). Examples of the derivatives include formazan Hydroxyethyl cellulose (MHEC), methyl hydroxypropyl cellulose (MHpc), methyl ethyl hydroxyethyl cellulose (MEHEC), ethyl hydroxyethyl cellulose (EHEC), hydrophobically modified Ethylhydroxyethylcellulose (HMEHEC), hydroxyethylcellulose (HEC), and hydrophobically modified hydroxyethylcellulose (hmhec) and mixtures thereof. The hydrophobic substituent may have 1 to 25 carbon atoms. Depending on its commercial composition, it may have a methyl or ethyl substitution degree (DS) of 0.05 to 25, a hydroxyalkyl moire substitution degree (HA-MS) of about 0.01 to 6, and a hydrophobic substitution The base φ Morse degree of substitution (HS_MS) is about 0.01 to 0.5 per anhydroglucose unit. Specifically, the present invention relates to these Water-soluble non-ionic cEs is used as an effective thickener and water-retaining agent in dry mortar-based mortars, for example, primer primer, single-layer primer, lightweight primer, decorative primer, skimming finish and / or finish Mortar, and External Finished Insulation System (EFIS). In the practice of the present invention, traditional CEs (second CEs) made from purified cotton linters and wood pulp can be used in combination with rcl-based CEs. Various self-purifying celluloses The preparation of CEs is known for this technology. These second ces can be used in combination with the first RCL-based CEs for implementing the present invention. These second CEs are referred to as conventional CEs in this case 101431.doc 10 200540139, because Most of them are known in commercial products or markets and / or documents.

US Patent Application Serial No. 10 / 822,926, incorporated herein, was prepared on April 13, 2004. The raw material for this specific example of the present invention is a mass of unpurified raw cotton fluff fibers having a bulk density of at least 8 grams per milliliter. At least 50% by weight of this mass of fibers has an average length that passes through a U.S. screen size of 10 (2 mm opening). The mass of the unpurified raw cotton linters is obtained by obtaining a loose mass for the first cut, the second cut, the third cut, and / or the operation of the unpurified, natural raw cotton velvet or a mixture thereof, which contains at least 60% Cellulose, as measured by AOCS (American Oil Chemists &gt; Society), Official Method Bb 3-47, and converted to loose mass to length, where at least ⑼% by weight of the fiber passed through a U.S. standard sieve size number. Cellulose ether derivatives are prepared using the above-mentioned converted mass of raw cotton fluff fibers as raw materials. Cutting of raw cotton linters «J 枭 block is first treated with cellulose in a pulp or high solids process at a cellulose concentration greater than 9% by weight to form an active cellulose age pulp. Then, the active cellulose is polymerized at a sufficient time and at a sufficient temperature to react with a mixture of a test agent and a chelating agent to form a cellulose ether derivative, and then recovered. It is known in the art to modify the above process to prepare various CEs of the present invention. CEs not included in the invention obtained in the RCL bag can also be cut from raw cotton linters and / or prepared from mills or manufacturers to obtain raw cotton linters, including the combination obtained by &quot; original, mechanical cleaning of raw cotton linters The substance 'is substantially free of non-cellulosic foreign substances, such as inclusions, crushed nitrate, seed shell, etc., and can also be used to prepare the fibrous tincture of the present invention. The mechanical cleaning techniques of raw cotton short weaves, including those involving destruction, selection and air separation techniques, are known to those skilled in the art. Using a combination of mechanical beating technology and air separation technology, the fiber is separated from the crushed nitrate by using the density difference between the fiber and crushed nitrate 10143l.doc -14- 200540139. Mixtures of mechanically cleaned raw cotton linters and, originally, raw cotton linters can also be used to make the cellulose ethers of the present invention. When comparing the cement-based mortar (or bottom ash) prepared by traditional cellulose ethers, the mortar mortar of the present invention provides water retention, thickening and sag resistance, which are important parameters widely used in this technology to characterize Cement-based mortar. According to European Norm EN 1015-8, the water retention rate and / or the water retention rate is "the ability of a fresh hydraulic mortar to maintain its ability to mix water when exposed to substrate suction". It can be determined according to European Norm EN 1 8555. Sag resistance is the ability to apply fresh mortar vertically to maintain its position on the wall, i.e. good sag resistance prevents fresh wet mortar from flowing downwards. Regarding ash destruction based on water / Nissan, it is usually subjectively evaluated by the responsible technician. It is concerned with the thickening of cement-based mortars after research. Thickening and / or flow can be determined according to DIN EN 18 5 5 5 using a consistency test bench.

Right dry at 15 (TCT is cleaved with hydrochloric acid and modified with Zeiss (~ ⑻). The reaction product is quantitatively determined by gas chromatography. 度 The viscosity of the aqueous cellulose scale solution is at a concentration of 1 amount. When the viscosity of the vitamin solution is determined, the weight is 101431.doc -16-200540139, and the corresponding methyl trimethyl cellulose is used, that is, the moisture content is compensated by the higher weight. Purified cotton linters or high-viscosity wood pulp are commercially available. • Methyl hydroxyalkyl cellulose is sticky and ancient. ^ $ Watts <viscosity has a viscosity of up to 2% by weight of aqueous solution 'is about 70,000 to 80 〇〇 〇mpas (push the right # 古 U and use a Brookfield RVT viscometer at 20 C and 20 rpm to measure with a shaft number of 7). To determine the viscosity, use a Brookfield RVT rotary viscometer. All in 2 The measurement in a wt% aqueous solution was performed using ah and ⑼—the number of shafts was 7. The sodium chloride content was determined by the Mohr method. 0.05 g of the product was weighed on an analytical balance and dissolved in 150 ml of distilled water. Then, after stirring for 30 minutes, add 1 mmol 15% HNO3. Thereafter, the solution was titrated with a standardized silver nitrate (AgN03) solution using a commercially available device. The water content of the sample was determined using a commercially available moisture balance at 105t. The quotient of the initial weight is expressed as a percentage. The surface tension of the aqueous cellulose solution is measured using a Kruss digital tensiometer K10 φ at 20 ° C and a concentration of 01% by weight. For the measurement of surface tension, the so-called "William Rice hanging sheet method ', in which the sheet is lowered to the liquid surface and the downward force of the pointing sheet is measured.

The results clearly show that the product of such high viscosity than commercially available type having a higher viscosity at a concentration of 2 wt%, the viscosity was found about 100,000 mPas. Due to its extremely high value, it is more reliable and easier to determine the viscosity of a 1% by weight aqueous solution. At this concentration, commercially available fluorenyl hydroxyethyl cellulose and methyl hydroxypropyl cellulose exhibit viscosities ranging from 73,000 to about 9,000 mPas (see Table 1). The measured value of products based on raw cotton linters is significantly higher than that of commercial materials. In addition, the data in Table 1 clearly show that cellulose-based staple fibers have lower surface tension than the control samples.

Hydroxyethyl cellulose made from pure raw cotton linters was manufactured in a Hercules experimental reactor. As shown in Table 2, the two samples had about the same hydroxyethoxy 101431.doc -18- 200540139 group content. However, the viscosity of the obtained HEC based on RCL is about 23% or more. Table 2.

Water retention is measured in accordance with DIN EN 18555 or internal Hercules / Aqualon operating procedures. Within 5 seconds, 300 g of dry mortar was added to the corresponding amount of water (at 20.0. After mixing the sample with a kitchen manual mixer for 25 seconds, the resulting sample was allowed to mature for 5 minutes. Then, the mortar was filled into the plastic ring, It is positioned on a piece of filter paper. Lu is between the filter paper and the plastic ring, and when the filter paper is placed on the plastic plate, the thin fiber web is positioned. The weight of the arrangement is measured before and after the mortar is filled. Therefore, the weight of the wet mortar is calculated. In addition, The weight of the filter paper can be known. After soaking the filter paper for 3 minutes, the weight of the filter paper is measured. Now use the following formula to calculate the water retention rate [%]: WRr%] = 1〇n. 10 ° xWUx (l + WF)

When the use level is reduced to 0.08%, the water retention rate of the bottom ash obtained from the coating is significantly reduced. In addition, the air content is also slightly reduced. Mortar density can be seen. In another test, 'mainly RCL MHEC series was tested at the addition level of 0.08%. 101431.doc -20- 200540139 Although the dose level was 20% lower than the control sample, water retention, air Content and fresh mortar density remain the same. In addition, A better thickening effect can be seen, which is shown by a lower flow value. In another test series, the water retention rate of the base coat and bottom ash is determined according to the CE · joining level. In addition, MHEC, which is based on RCL, is also associated with Control (MHEC 75000) comparison. The results of this study can be seen in Figure 1. It can be shown that RCL-based MHEC has better coating properties than the currently used very high viscosity MHEC. Especially, at lower CE -At the dose, • You can see the obvious advantages of using RCL as the main material. Here, at the same addition level, a higher water retention rate can be achieved, that is, the same water retention rate can be achieved at a significantly reduced dosage.

When the corresponding value decreases by about 0.7%, it exceeds the experimental error (± 0.5%). RCL-MHPC can also be tested at a reduced dose level of 20%. Nonetheless, the water retention of the resulting primer ash and the properties of the wet mortar from other studies can be compared with the control sample, which was tested at a higher level of addition. In another test series, the water retention of the base coat and bottom ash was determined based on the CE-joint level. In addition, MHPC based on RCL was also compared with control MHPC 65000.

This effect is shown by the lower flow / dispersion value of the bottom ash containing RCL-MHEC. When the water factor is increased from 0.2 to 0.21, similar mobility can be determined. However, similar water retention can be measured even at increased water factors. All other characteristics can also be compared. These tests clearly confirm that the RCL-based MHEC has a better coating performance compared to the water retention capacity of the currently used high-viscosity MHEC as a control sample. In particular, at the lower CE dose level, the obvious advantages of using RCL as the main material can be seen. Here, at the same addition level, a higher water retention rate can be achieved; that is, the same water retention rate is achieved at a significantly reduced dose level. The data in Table 10 and Figure 4 clearly show that RCL-based MHEC is an effective cellulose ether, which shows similar coating performance at a reduced addition level. 101431.doc -29- 200540139 Depart from the scope of the change and modification of this issue.
