EXAMPLE III Without fragrance overflowing The butterfly flies fall on the bottom of the glass tank, and the insect prevention section is unchanged The mouse has weak vitality and no change in the rat-proof section
Example four Without fragrance overflowing The butterfly flies fall on the bottom of the glass tank, and the insect prevention section is unchanged The mouse has weak vitality and no change in the rat-proof section
Comparative example Slight fragrance spillage The butterfly flies dancing and gathering near the insect-proof section Strong mouse activity and preventing serious damage of mouse segment
According to the table, the sample prepared in the first embodiment has certain deodorization performance, the samples prepared in the second embodiment to the fourth embodiment have tight adhesion on the inner wall of the rat-proof section, excellent deodorization performance and can effectively isolate odor from overflowing, the latex particles are adopted in the comparative example to prepare the floor drain pipe, the inner wall of the rat-proof section can be adhered together due to the fact that the floor drain pipe is soft, the purpose of isolating odor to a certain extent can be achieved, but the latex particles are simply adopted in the comparative example, the insect and rat prevention effect cannot be achieved, the floor drain pipe of the sample prepared in the embodiment has excellent insect and rat prevention performance, and the floor drain pipe prepared in the application is simple in structure and low in cost and has excellent deodorization, insect and rat prevention effects.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
