INSTRUCTION OF THE INVENTION (1) The present invention relates to a method of applying a paste for a wallpaper, etc., in order to promote fluidity in an aqueous solution after adding a fluidity promoter to a water-soluble cellulose ether. It is a water-soluble cellulose ether composition and paste which is easy to apply, has good work efficiency and is economical. In the prior art, as a paste for wallpaper, a water-soluble starch solution called "paste" is usually used. These pastes must be used in a solid content of about 20%, which is a thick starch paste solution, which is usually diluted several times to about 10 times with water. Further, the solution is also marketed, and formaldehyde water, a preservative, and the like are added for long-term storage. Recently, a method in which a powder or a granule of a water-soluble cellulose ether which is a soluble type is dissolved in use at the time of use is generally used in consideration of environmental problems and the like. The advantage of using the instant water-soluble cellulose ether is that it can be stored in a solid form until it is used without adding a preservative, etc., and it can be used in a small amount in a small amount as compared with a high viscosity such as starch. However, the paste for wallpaper containing water-soluble cellulose ether has a very high viscosity of the solution, so that the coating thickness of the unnecessary paste is thickened, and it is easy to apply when coating with a brush or a roller at a time. The shortcomings of the spot. The present invention provides a fluidity promoter when a liquidity promoter is added to a water-soluble cellulose ether to improve the disadvantage, and is easily coated when used as a paste for wallpaper, etc. Further, water-soluble cellulose ether compositions and pastes which are excellent in work efficiency and economical efficiency are intended. In order to achieve the object, the inventors of the present invention conducted a precise begging and found that the water-soluble cellulose ether can be effectively promoted by the use of a flow promoter in the water-soluble cellulose ether. The Chinese National Standard (CNS) A4 specification (210 X 297) can be effectively promoted.公) ------------------ (Please read the phonetic transcription on the back?

Description of the Invention (2) The water-soluble fluidity of the cellulose ether composition, and further the present invention. Therefore, the present invention provides (1) a water-soluble cellulose ether composition characterized by containing a water-soluble cellulose ether and a fluidity promoter, and (2) the fluidity promoter is a polyether compound or a derivative thereof or The organic phosphorus-based surfactant is a water-soluble cellulose ether composition characterized by (1), and (3) a paste formed from the water-soluble cellulose ether composition contained in the above (1) or (2). Agent. The present invention will be described in more detail below. The water-soluble cellulose ether of the present invention is not particularly limited, and hydroxypropylmethylcellulose or hydroxyethylmethylcellulose is generally used. The viscosity is used at a viscosity of 1% aqueous solution at 25 ° C for 10 to 22000 mPa · s, preferably 1 〇 0 〜 lOOOO mPa · s. When the viscosity is less than 10 m P a · s at a viscosity of 1% aqueous solution, the required viscosity is insufficient or the addition amount is not large, and when the viscosity is too high, workability is poor. The shape of the water-soluble cellulose ether may be either a powder or a granule, but it is preferable to use a granule having a less powder in consideration of the operability. Further, the composition of the present invention may be dissolved in water as a paste or the like, but the amount of water-soluble cellulose ether added to water is 0.2 to 5 % (% by weight, the same below), preferably The best is 0.5 to 3%. When the amount of the water-soluble cellulose ether added is less than 0.2%, the tackiness is insufficient to cause poor adhesion, and if it is more than 5%, the viscosity is too high, resulting in poor workability and high cost. Examples of the fluidity promoter of the present invention include a polyether compound or a derivative thereof or an organophosphorus surfactant. Specifically, as a polyether (please read the notes on the back and fill out this page) --_ 订--- ___________ — — — — ——____ This paper scale applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -5- 1251044 A7 B7 V. INSTRUCTION DESCRIPTION (3) Examples of compounds or derivatives thereof are ethylene oxide polymers and propylene oxide polymers, which are collectively referred to as prlonic series. Copolymer of 垸-epoxy propylene compound 'activator (especially nonionic surfactant) such as these derivatives, polypropylene glycol, polyethylene glycol, glycerin, Jorusin LX, Jorusin PB, Jorusin LB manufactured by Daifain Co., Ltd. -D and other examples. Further, examples of the organic phosphorus-based surfactant include tributyl phosphate and sodium octyl phosphate. The amount of the fluidity promoter to be added is not particularly limited, and it is preferably 0.1 to 20% by weight of the water-soluble cellulose ether, and particularly preferably 0 to 5 to 10%. When the amount added is less than 0.1%, the effect of effectively improving the fluidity cannot be obtained. On the contrary, if it is more than 20%, not only the liquidity promoting effect is too strong, but also the problem of too high cost is generated. In addition, as an example of the method of adding a fluidity promoter to a water-soluble cellulose ether, the fluidity promoter may be directly added to an aqueous solution of a water-soluble cellulose ether, stirred and mixed, but it may be added in advance in consideration of operability and the like. The fluidity promoter is preferably one of the water-soluble cellulose ethers. Namely, a method in which a water-soluble cellulose ether is preliminarily impregnated with a fluidity promoter, and a immersion fluidity promoter is dry-blended in a water-soluble cellulose ether such as fine powder of ceria. The fluidity promoter is entrapped in the air bubbles when the solution is stirred, and the defoaming effect is removed, so that the bubbles can be removed and the effect of the uniform solution is twice.

The initial viscosity was stirred for 5 minutes, and then left for 1 hour, and then evaluated. The solution fluidity was measured by suspending 20 g of each solution at a rate of 40 ° glass rods and measuring the length of the flowing solution from the top of the rod. The longer the solution length, the better the solution is improved, and vice versa.
