粉末糊に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder paste. More specifically, the present invention relates to initial tackiness,
The present invention relates to a powder paste which is good in properties such as viscosity and which is also useful as an interior paste such as wallpaper which can improve antiseptic property.

なか普及しないのが実情である。2. Description of the Related Art Conventionally, powder paste has attracted attention because it is far more advantageous than paste paste in terms of storage and storage properties, transportability, and handling property during use. Is also manufactured and sold. However, as the paste for interiors such as wallpaper construction, paste-like paste still occupies the mainstream, and powder paste is not widely spread.
【０００３】その理由としては、従来の粉末糊の場合に

あるなどの欠点があった。また、コスト面においても、
粉末糊には問題が残されてもいた。It is considered that the reason for this is that the conventional powder paste has disadvantages such as inferior initial tackiness and lack of stickiness, and further that it takes time to dissolve and stir. Moreover, in the case of the conventional powder paste, the antiseptic property and the antifungal property are not always satisfactory, and in order to improve this point, as a powder different from the conventional paste, or as a liquid, a preservative or an antiseptic agent is used. Although a composition containing a fungicide has been tried, in this case, there is a defect that a dedicated dissolution stirrer is required. Also in terms of cost,
Problems still remained with the powder paste.

を必須としている。The above-mentioned powder paste will be described in more detail. The conventional powder paste of the present invention is a mixture of flaky powder and fine powder, and the shape characteristics of the powder and the specific gravity and water content are adjusted. Based on the finding that it has not been achieved, and that by controlling these points to the required ones, excellent initial tackiness, stickiness, and other properties can be obtained, and solubility and economic efficiency can be improved. It was completed based on this. Therefore, the powder paste of the present invention has the composition component of the crosslinked etherified starch paste as described above, and has a bulk specific gravity of 250 to 390 kg / m 3 , a water content of 30 to 90 mg / g, and a 125 μm sieve. It is essential that the flake powder has a particle size of 5% or less.

As the crosslinked etherified starch, those produced by various methods are considered, but in the present invention, for example, potato starch is preferably treated with alkylene oxide, epichlorohydrin, glycidyl ether, glycidyl ester, etc. in the presence of a base catalyst. The reaction is conducted, and the obtained crosslinked ether compound is neutralized and dried to obtain a predetermined shape condition.
