Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an F base material capable of preventing damage caused by cement mortar that is applied on a wall surface, and a method for manufacturing the same.

The conventional Molcle F base material is 1μ, and the following types are known.

■ Substrate surface surface: Emano V john or Denkus with Kuroiso particles C added, and then 7km kneaded to make the surface uneven. -c Dry.

[Yes] After fully forming the waterproof layer on the surface of the base material, mark the next page with ■
Processed.

[Yes] A waterproof layer is formed on the surface of the base material, and an inorganic binder (a mixture of cement and light foam resin coating) is applied to the foot plate and the base material and dried.

However, since the above-mentioned 7 IV Kurt ground My ml is also hard, the cement mortar is dry and deep, and the cement mortar is transformed into one piece by the Oki-1 outside force. It is possible to completely prevent the formation of layers, but there is a drawback that turtle B occurs in the cement mold of the clothes.

This invention solves the above-mentioned drawbacks, and will be explained in detail below with reference to Examples.

In FIG. 1 and FIG. 2, 1 is a base material.

Examples of the base material include plywood, particle board, fiberboard, gypsum board, asbestos slate board, pulp cement board, calcium silicate board, and the like. Note that, if necessary, a sealer may be applied to the surface to further improve waterproofness or to impart alkali resistance. 2 is a waterproof layer, which is formed by applying a paint containing elastic particles or powder 6 such as natural rubber or synthetic rubber to asphalt, acrylic/urethane/vinyl synthetic resin, etc. There is. Size T of the above particles or powder B
Particles having a size of I'i of several microns to about 5 microns are preferable, but in consideration of price, workability, etc., particles of about 100 μm to LSm are most preferable. If the particles are of this size, when the waterproof layer 2 is formed, the particles 6 will protrude from the surface of the waterproof layer 20, and the coating will be on top of them! This gives rise to the advantage of physically attaching the +. This is an aggregate-containing paint layer formed on the surface of the 4Vi waterproof layer 20.

This paint layer 4 is made by mixing aggregate 5 with one or more mixtures of asphalt, acrylic yarn, urethane type, vinyl yarn, etc., and then drying the mixture.

1: At the time of writing, the surface may be roughened by forming irregularities on the surface due to the aggregate that is being crushed, as shown in Figure 1. As shown in Figure 2, the paint itself is applied in an uneven pattern and dried. Good too. As the coating method, any method may be employed, such as spraying, coating using a roll coater, or rolling the coating onto the base material and scraping it off with a grade. Further, if this coating N is applied when the waterproof layer 20 is semi-dry, the concave shape with the waterproof layer 2 will be improved. The tung fat used may be any of emulsion thread, water thread, and oil-based fat. Although there are many different types of asphalt, it is preferable to use the emulsion type produced by Yukino and F.T. - Also, as aggregates for toilet use, cement, carbonic acid runium, resin, resin, half balloon, vermiculite, 6 persimmons, rock wool 1 volume styrene beads.

It can be said to be 11ekawachoi by combining one or edan. When the surface of the aggregate-containing paint layer is roughened as in this embodiment, there is an advantage that the physical adhesion of the cement mortar applied thereon is improved. In addition to the general mortar finish, wax can also be applied to the surface of any type of finish, such as a sukutsuko finish or a ricin scrape finish.

As mentioned above, this invention has a base material surface ζ, natural rubber,
By forming a waterproof layer with elastic particles or powder such as synthetic rubber added, the above waterproof layer can be used to prevent drying shrinkage of cement mortar used as a surface finishing agent, shrinkage due to changes in substrate humidity, etc. has the great effect of acting as a buffer layer and preventing cracks from forming in cement mortar, etc. It also has young fruits whose adhesion to cement mortar is improved due to the roughened surface of the paint layer mixed with aggregate. In addition, the present invention has the effect that it is possible to extremely easily produce a base material that can prevent cracks in mortar without requiring any complicated processes, and that it is possible to provide a high-quality base material at a low cost. have
