Description of the Invention (,) This invention is related to the cement mortar cement with high viscosity at high temperature. It is more detailed than the prior art. It can show viscosity at higher temperature with less added amount. The most important characteristic of the main cement mortar is the moisture retention rate of cement mortar. It is still possible to obtain high penetration cement cement infiltration agent at high temperature. In the prior art, hydroxyalkyl alkyl fibers of non-ionic fiber ether have been used in tile mortars since ancient times to ensure their moisturizing properties and improve coating workability. By adding hydroxyalkyl alkyl fibers to the tile mortar, the moisture retention of the tile mortar can be increased to prevent dryout, so the jointability of the tiles can be improved. In addition, in order to improve the workability of the painting and prevent the unevenness of the tiles, the addition of polypropylene amidamine as described in the Special Fair 3-1 3 1 8 3 Bulletin, such as: The Special Fair 1-4 4 6 6 4 The addition of starch is proposed. The mixing method of tile mortar is as follows. ① After adjusting the aqueous solution of hydroxyalkyl alkyl fiber at the construction site in advance, mix this solution with cement and fine aggregate, and then make a tile mortar method (water bottle method). ② After mixing hydroxyalkyl alkyl fiber with cement and fine aggregate in advance, add water at the construction site and then make a tile mortar method (that is, blending (pre-mixed molding compound)). ③ After mixing cement with fine aggregate and hydroxyalkyl alkyl fiber at the construction site, and adding water after mixing, it is made into a porcelain barrier mortar method. (The on-site blending of this paper applies the Chinese National Standard (CNS) A4 specifications ( 210X297 mm) (Please read the notes on the back before filling out this page) -4- 565541 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs _ V. Description of Invention (2) Method). The above ① water bottle method is particularly expected to have an excellent operation method with a small amount of powder, and a hydroxyalkyl alkyl fiber which can show viscosity after being slightly dispersed and dissolved. Generally, hydroxyalkylalkyl fibers have temperature dependence, the lower the viscosity of the aqueous solution, the greater the viscosity, and the lower the temperature below the gelation temperature. Therefore, in the "water bottle method, the water temperature rises in summer, and the viscosity of the aqueous solution decreases". There is a cost problem that a large amount of water cannot be added. In addition, since the tile mortar in summer is also hot, there is a problem of reducing the moisture retention rate. In addition, the above-mentioned additives such as polyacrylamide and starch cannot improve the above-mentioned problems related to temperature. '"From the above, granular hydroxyalkyl alkyl fibers that do not reduce viscosity at high temperatures in summer, and also have very low moisture retention, high dispersibility, and high solubility are expected. The present inventors have carefully studied and improved the foregoing prior art After the shortcomings, it was found that after the high-molecular-weight pulp was used as the raw material to produce the hydroxyalkyl alkyl fiber, the viscosity of the aqueous solution at 1% by weight and 20 ° C was 4,000 to 20,000 mPa · s. Ultra-high viscosity products can be manufactured, and by improving the amount of etherifying agent, reaction method, cleaning method, surface treatment method, etc., the product can be manufactured to maintain high aqueous solution viscosity at higher temperatures That is, the present invention has been completed. That is, the present invention is directed to a 1% by weight aqueous solution with a viscosity of 4,000 to 20, 000 mPa · s at 20 ° C. This paper size is subject to the Chinese National Standard (CNS ) A4 specification (210X297 mm) (Please read the precautions on the back before filling this page) -5- 565541 Printed by A7 B7_5, the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, 5. Description of the invention (3), the viscosity at 35t is 1, 5 00 ~ 12,000 mPa · s hydroxyalkyl alkyl fiber composed of cement mortar for cementing agent. Among them, the above hydroxyalkyl alkyl fiber is 30% by weight or less in the coarse form of 30 mesh screen At the same time, those who are finer than 200 mesh sieve are 30% by weight or less, and those whose wetness time is less than 10 seconds are suitable for granular products. The invention will be described in detail below. Form] Examples of the cement mortar penetrant which can be used in the present invention are: protland cemente (ordinary cement, fast-hardened portland cement, medium heat cement, white cement, ultra-fast hardened portland cement), etc. Other examples include mixed cement (blast furnace cement, silica dioxide, fly ash cement), special cement (aluminous cement, expanded cement), etc., among which one or two or more kinds are selected. The present invention In addition to the infiltration agent, hemihydrate gypsum, slaked lime, calcium carbonate, dolomite lime mud powder, clay, clay fiber, vinylon fiber and other fibrous substances and polypropylene amidamine, starch and other additives can be added to the cement mortar. ... and As a fine aggregate, chuan sand, mountain sand, cold water sand, lightweight aggregate, etc. can be used if necessary. Emulsions such as EVA can also be blended. As the hydroxyalkyl alkyl fiber of the present invention, only 1% by weight The viscosity of the aqueous solution at 40 ° C is 4,000 0. ~ 2 0, 〇 0 Ό m P a • s, preferably 5,000 ~ 15, 2000 mPa · s, and the viscosity at 35 ° C 1,500 ~ 12,000mPa · This paper size applies Chinese National Standard (CNS) A4 specification (210X297mm) (Please read the precautions on the back before filling this page) -6- A7 565541 _B7_ V. Invention Note (4) (Please read the precautions on the back before filling in this page) s, preferably 2,000 ~ 8, 000mPa · s, and more than 30 weight less than 30 mesh screen coarse form, Those with less than 30% finer form than the 200 mesh sieve can be prepared, and they can be widely used without limitation. Specifically, examples of usable materials include hydroxyethylmethyl fiber, hydroxypropylmethyl fiber, and hydroxyethylethyl fiber. It is known that the viscosity of the aqueous solution of the hydroxyalkyl alkyl fiber is different due to its dispersion and dissolution method. After stirring for a long time at the high share of the unbroken molecular chain, those who dissolve at low temperature can become those with high viscosity. In addition, since an aqueous solution of a hydroxyalkylalkyl fiber has thixotropy, it is known that the external viscosity of the hydroxyalkylalkyl fiber differs depending on the velocity of the mineral rock when measured with a rotational viscometer. Among them, the method of dispersing and dissolving the viscosity prescribed in the present invention is the one with the lower share as shown below. Method for dispersing and dissolving hydroxyalkyl alkyl fibers: Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs · Put the quantitative amount (1% by weight) of hydroxyalkyl alkyl fibers into water and stir in a magnetic stirrer for 5 minutes Then, after standing for 60 minutes, the external viscosity was measured with a B-Η-type rotational viscometer at a drum rotation number of 20 rpm. The temperature is maintained at a predetermined temperature by dispersion and dissolution. When 1% by weight of the hydroxyalkylalkyl fiber in the present invention has a viscosity of the water solution at 20 ° C of less than 4,000 mPa · s, the necessary moisture retention cannot be ensured in the cement mortar. Conversely, when the viscosity of a 1% by weight aqueous solution is greater than 20,000 hydroxyalkylalkyl fibers of P a · s', the current Chinese paper standard (CNS) A4 specification (21〇 &gt; &lt; (297 mm) &quot; 565541 A7 B7 V. Description of the invention (5) The technical aspect of industrial production is extremely difficult. If it is to be manufactured, it will have to pay an uneconomical side with extremely high costs. The viscosity of the aqueous solution is the same at 35 ° C. Generally, the particles of the ‘base fiber’ dissolve at a very fast rate. When the powder is directly dissolved in water, a polymer adhesion phenomenon occurs, and the water that penetrates into the polymer adhesion phenomenon is limited, and its dissolution is extremely slow. Therefore, the use of glyoxal or the like for surface treatment does not cause polymerization and stickiness, but has the disadvantage that the viscosity appears to be slow. Therefore, in the above water bottle method, aggregation and adhesion do not occur under slight agitation, and those who can quickly develop viscosity are expected. In contrast, the powder particle size of the present invention is less than 30% by weight than the coarse morphology of the 300 mesh sieve and less than 30% than the fine morphology of the 300 mesh sieve, which is resolved by slight surface treatment. Taking slight surface treatment as an example, adding 0.2% of glyoxal and 0.1% of diol to hydroxyalkylalkyl fiber will not cause the phenomenon of polymerization and adhesion, and can accelerate the dissolution time. The amount of etherification during the reaction is also extremely heavy. When the diol ring unit of the fiber, the degree of substitution according to the average number of substituted hydroxyl groups (hereinafter referred to as DS), and the substituents added to the diol ring unit of the fiber The average Mohr number is determined in place of the Mohr number (hereinafter referred to as MS). DS is 1 or more, and MS is more than 0.15. When the hydroxyalkyl alkyl fiber is reacted, a more heterogeneous reaction method or a more uniform reaction method may be adopted. However, in order to ensure a more uniform reaction at a high temperature, it is preferable to use salty soda salty fiberization.

Those with high performance. Conversely, the compound of Comparative Example 1 has a low heat of MS of 0.10. Therefore, the viscosity is greatly reduced at 35 ° C, and the moisture retention of the tile mortar is also low. Among the compounds of Comparative Example 2, There is too much ash, and the consolidation phenomenon is caused by inorganic salts during drying. It cannot be dispersed and dissolved with the slight stirring implemented by the present invention. Jump to the standard Tsukuni Kokuto T Yongtong 7 9. 2 -14- 565541 A7 B7___ 5. Description of the invention (12) The compound of Comparative Example 3 is powdered hydroxypropylmethyl fiber, which is 57.0% smaller than that of 200 mesh sieve. And glyoxal is as high as 0.9%. Therefore, during the slight stirring practiced in the present invention, the primary dispersant precipitates and forms a paste at the bottom (the viscosity cannot be measured), which has a practical problem. The compound of Comparative Example 4 had a size of 38% or more with a 38 mesh sieve, and the particles were too coarse. Therefore, with the slight stirring carried out by the present invention, it precipitates after one dispersion, and most of them form a paste at the bottom, and no stickiness appears, so it is extremely impractical. Among the compounds of Comparative Example 5, M S was as small as 0.15, and there was no uniform reaction, or it was too rapid during drying. Therefore, the viscosity was greatly reduced at 35 ° C, and the moisturizing rate of the tile mortar was also low. By using the cement mortar mixing agent of the present invention, compared with the prior art mixture, its viscosity at high temperature appears, and the moisturizing rate of the cement mortar at high temperature becomes higher. The joint effect is remarkable, and its industrial significance is extremely great.
