Description

  The present invention relates to a finishing material for a building that can be comfortably used by animals such as dogs that live together with human beings indoors while having the conventional performance necessary for a human to live comfortably.

Conventionally, floor coverings, counters, and waist walls, which are finishing materials for homes, have been pursued for the purpose of a comfortable life for humans.
In terms of slip resistance on the surface of flooring, an index established from the viewpoint of human walking C.I. S. R values are generally used, and floor materials having a slip resistance of 0.3 to 0.5 that are not slippery to the extent that they do not slip and fall properly are generally in circulation.
However, this figure is a figure that is considered to allow humans to walk comfortably. Therefore, there are many cases where it is considered that the living environment with such a finished flooring is not a comfortable living environment for care dogs that need to live with people, and for animals such as dogs and cats kept as pets indoors. is there. For example, with a hard floor finish, dogs and the like have problems such as slipping, falling, or dislocation of the hip joint in severe cases. In addition, phenomena such as cats slipping off beams and counters that have jumped on have been seen. These phenomena cause mental stress to pets such as dogs and cats living indoors, and cause undesired behavior such as biting or urinating things.

With the declining birthrate and aging population, there is an increasing demand for symbiosis with care dogs and pets that comfort the heart, and building materials that can meet this demand are being demanded.
In order to meet the above-mentioned demand, special tile carpets (Patent Document 1) that are partially or entirely laid indoors as flooring materials have been proposed, but for people and pets that can be constructed in the same way as conventional flooring materials. There is no known flooring that can be used.
JP 2003-143990 A

Conventionally, since it was not common for people to live with animals such as dogs and cats in the same room, rugs for laying on a part of the floor such as a special mat or tile carpet have been used. With such a rug, there is a problem that it is not possible to deal with an animal accompanying a place where there is always a person like a care dog, that is, a living room, a kitchen, a toilet, and the like.
The present invention is a building material that does not give stress to animals such as dogs and cats without giving a sense of incongruity to humans, by simply applying to the surface of solid materials, plywood, etc., which are conventionally used as base materials for building materials, It is intended to provide building materials that can be used for flooring, waist walls, beams, etc. by cutting, cutting, etc. in the same way as conventional building materials.

  The inventors of the present invention are suitable as a coating material for building materials such as floor materials and board wall materials, and wood materials such as furniture, and the formed coating film has appropriate elasticity against indentations and scratches and is self-repairing. As a result of various investigations for a coating composition which is a certain coating composition and has good habitability for companion animals, it can be achieved by blending the coating composition with organic polymer particles having a core / shell structure. As a result, the present invention has been completed.

The building material for pets of the present invention is characterized in that a coating film having elasticity and resilience and having a fine uneven surface is formed on the surface of a building material base material such as solid wood or plywood, if desired. is there.
The coating film can be obtained by applying a coating composition formed by blending organic polymer particles having a core / shell structure with a coating material composed of a curable soft or semi-rigid polymer.
Therefore, the building material for pets of the present invention can be obtained by applying the above coating composition to a required thickness on a conventional base material for building materials.
Furthermore, the present invention relates to a coating composition for pet animals comprising a coating component comprising a curable soft or semi-rigid polymer and organic polymer particles having a core / shell structure.

  The present invention adds organic polymer particles having a core / shell structure to a paint that is self-restoring with respect to indentations, scratches, etc., and adjusts the addition amount of the polymer particles and the constituent materials of the core / shell. Thus, it is possible to obtain a building material that is excellent in habitability for pets such as dogs and cats as well as people.

  As the curable soft or semi-rigid polymer (hereinafter referred to as curable polymer) as the coating component in the present invention, those capable of forming an elastic and restorable film when cured can be used.
