Description

The present invention relates to a paint roller for painting building materials such as inner walls, outer walls, pillars, roofs, or floors of buildings.

When constructing a concrete structure generally called "exposed (uchihanashi, uchipanashi)" (hereinafter referred to as "exposed structure"), the state in which the formwork is removed after placing (or a state in which a transparent water-repellent agent is applied to the concrete surface) is the finish.

This type of exposed structure has a unique material texture with an exposed gray concrete surface. On the other hand, exposed concrete surfaces without surface protective materials such as porcelain tiles and stones deteriorate quickly over time due to wind and rain. Therefore, in order to maintain the exposed structure, it is necessary to perform maintenance work for maintaining and repairing the concrete surface.

In this regard, in Patent Document 1 below, a surface treatment process is performed in which a surface treatment agent containing an aqueous solution of a metal silicate as a main component is applied to building materials such as the inner walls, outer walls, pillars, roofs, or floors of buildings. It discloses a building coating method for forming a vitreous protective film on the surface of the building material.

Japanese Patent Application Laid-Open No. 2021-55400

In the building coating method disclosed in Patent Document 1, a surface treatment agent in which a white pigment and a black pigment are dispersed and blended in an aqueous solution of a metal silicate is applied to the surface of the building material to create an exposed structure-like effect. Provides a protective film with texture. In this case, it is disclosed that the surface treatment agent can be applied by brush coating, roller coating, spray coating, or the like.

However, in order to give the surface of the building material a high-quality exposed structure-like texture, it is necessary to use a painting pad to draw irregular black and white patterns, and this finishing work requires labor costs. and time cost.

The present invention was developed in view of the above technical problems. The purpose is to provide a good paint roller.

The paint roller of the present invention for solving the technical problem is a paint roller comprising a handle and a roller body rotatably attached to the handle, wherein the outer peripheral surface of the roller body is It is characterized by being constructed by an aggregate of sponge pieces (hereinafter referred to as "the roller of the present invention").

A preferred embodiment of the roller of the present invention is one in which the particle size of the sponge pieces is 3 to 50 mm.

According to the present invention, for example, irregular patterns can be easily imparted to building materials such as inner walls, outer walls, pillars, roofs, and floors of buildings.

FIG. 1 is a perspective view showing one embodiment of the roller of the present invention. FIG. 2 is a front view showing an enlarged sponge piece in the roller of the present invention.

Embodiments of the invention will be described below, but the invention is not limited to these embodiments.

<Invented Roller (1)>
FIG. 1 shows one embodiment of the roller 1 of the present invention. The roller 1 of the present invention comprises a "handle (2)" and a "roller body (3)".

-Handle 2-
The handle 2 comprises a grip 21 , a handle arm 22 and bearings 23 . The grip 21 is a part that an operator grips when using the roller 1 of the present invention. On the other hand, the handle arm 22 is a bent rod extending from one end of the grip 21, and a bearing 23 is attached to the tip bent in a direction perpendicular to the grip 21. As shown in FIG.

-Roller body 3-
The roller body 3 has a hollow cylindrical overall shape, and is attached to the handle 2 while being fitted onto the bearing 23 of the handle 2 . When the roller body 3 is impregnated with paint and rolled while being pressed against the object to be coated, the paint can be adhered to the object to be coated. Further, in the present invention, the outer peripheral surface of the roller body 3 is constructed by an aggregate of sponge pieces 31 . In this embodiment, a plurality of sponge pieces 31 with a particle size of 10±5 mm are prepared by shredding the urethane sponge manually, and these pieces are adhered around the bearing 23 of the handle 2 with an adhesive. Then, the roller main body 3 was constructed by stacking them until they had an appropriate thickness.

Since the outer peripheral surface of the roller main body 3 of the roller 1 of the present invention having the above structure is constructed by an aggregate of sponge pieces 31, the outer peripheral surface of the roller main body 3 has irregular irregularities. Also, the amount of paint absorbed by the roller body 3 is partially different. For this reason, if a coating operation is performed using the roller 1 of the present invention, the contact pressure of the roller body 3 with respect to the object to be coated becomes irregular, and the adhesion of the paint to the object to be coated becomes uneven. An irregular pattern is given to the object.

For example, when a surface treatment agent in which a white pigment and a black pigment are dispersed in an aqueous solution of a silicate metal salt is used as the paint, and a building material is selected as the object to be painted, a high-quality coating is applied to the surface of the building material. It is possible to give the material feel of an exposed structure.

The irregular pattern imparting by the roller 1 of the present invention can be carried out by a very easy operation of simply pressing the roller body 3 impregnated with the paint against the object to be coated and rolling it. can.

By the way, in the present embodiment, the sponge pieces 31 are made by shredding urethane sponge, but in the present invention, the sponge pieces 31 are not particularly limited as long as they are made of a porous and flexible material. The shape of the sponge piece 31 is also not particularly limited.

Further, in this embodiment, the sponge pieces 31 forming the outer peripheral surface of the roller body 3 have a particle diameter of 10±5 mm, but the size of the sponge pieces 31 is not particularly limited in the present invention. Also, there is no need to make the sizes of the sponge pieces 31 uniform. Specifically, the particle size of the sponge pieces 31 is preferably 3 to 50 mm (more preferably 5 to 30 mm).

Here, in the present invention, the "particle size of the sponge piece (31)" means the diameter when the sponge piece 31 is assumed to be a perfect sphere. Specifically, as shown in FIG. 2, it means the diameter (D) of the smallest phantom sphere (B) that can contain the sponge piece 31 .

In addition, the invention may be embodied in various other forms without departing from its spirit or essential characteristics. Therefore, the above-described embodiments are merely illustrative in all respects and should not be construed in a restrictive manner. The scope of the present invention is indicated by the claims and is not restricted by the text of the specification. Furthermore, all modifications and changes within the equivalence range of claims are within the scope of the present invention.

INDUSTRIAL APPLICABILITY The present invention can be suitably used as means for imparting a protective film having a texture of an exposed structure to building materials such as inner walls, outer walls, pillars, roofs and floors of buildings.
