ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the creation of a new method for producing cement straw by combining cationic Golatex'ffO:s with a raw material mixture for conventional cement straw. This is an epoch-making invention that has been able to significantly improve various performances such as 0 cement (for example, Portland cement, blast furnace cement, silica cement) and hard fine bone. Material (
It has a maximum particle size of 5 mm, has an appropriate particle size arrangement, and is clean.
(Hard, durable, and does not contain harmful amounts of dust, dirt, organic matter, etc.) and the raw material mixture are thoroughly stirred, and a solution of cationic rubber latex and water mixed in advance is added and kneaded to create mortar dough. After filling the cement into a straw-shaped formwork and curing it after molding (for example, curing it in a room with a constant temperature of 5°C or more and a humidity of 70 degrees or more at 300 degrees or more, and then curing it for 10 days) - rather, use cloth, etc. Cationic rubber latex mixed cement is used to produce straw.
次に、本発明の作用効果を実施用例により説明する。Next, the effects of the present invention will be explained using practical examples.

である。Conventionally, it has been said that the strength and water permeability of cement roof tiles depend on the physical properties of the cement itself and the compression achieved in the manufacturing process. In the method of the present invention, the adhesive force between the cement and the bone fragments is significantly increased, thereby increasing the strength and reducing the water permeability. Threads, cement, and hard bone particles are charged with negative ions (negative charges) in water. On the other hand, since cationic rubber latex is charged with cations, it can electrically bond between cement particles and fine bone particles, forming a complete cement-rubber composite. This can also be proven through electron micrographs. The specimen is cooled with liquid nitrogen and crushed in steps 1 to 1.
When observing a photograph taken of the fractured surface using the replica method, it is clear that at 160x magnification, the overall appearance can be clearly seen.In the case of a cationic rubber latex mixture, silica sand can be barely identified in the paste phase, and the fracture occurs in that state. Because of this, a clean fractured surface of the silica sand (fine aggregate) can be observed. On the other hand, in the case of normal mortar, the silica sand is not broken, but is completely removed from the paste, and only the silica sand that is filled is observed. Furthermore, when observing the entire paste phase at a magnification of 16,000 times, the cationic rubber latex mixture showed that
While it has a wavy shape, regular mortar has a jagged fractured surface. Considering that the size of the irregularities is almost comparable to the size of cement particles, it is thought that the fracture surfaces between cement particles are carefully monitored. Judging from these facts, the cement tiles mixed with cationic rubber latex according to the method of the present invention can fundamentally improve all the properties of conventional cement tiles. Excellent flexibility, weather resistance, durability, and waterproofness. In addition, the quality has been improved by more than 20% in strength from 30 to 1-1 water permeability, has good contact with paint, and can preserve its beauty for a long time. It is effective.
