Test example
The anti-cockroach effect of the ceramic tile anti-cockroach agent prepared in examples 1 to 7 and comparative examples 1 to 5 was tested, and the test device and the test method were as follows:
preparing the cockroach-preventing ceramic tile: 5.0 g of cockroach-preventing agent is sprayed on the surface of a 400 x 400mm ceramic tile, the ceramic tile is placed in a shade place for 12 hours, and the test is carried out after the surface of the ceramic tile is dried.
In a transparent acrylic box body with the square of 150 x 150cm, air holes are reserved on the top of the box body. 5cm of openable window is arranged on the side surface of the box body and is used for feeding feed and water.
The cockroach-preventing ceramic tile is placed in an acrylic box, and meanwhile, feed and a small amount of water are placed. The window was closed and the ambient temperature was set at 28 degrees celsius and humidity at 60%. During testing, 50 adult German cockroaches are placed in each acrylic square box. And after the test is finished, observing and recording the death number of the cockroaches, and calculating the repelling rate. The repellent rate is equal to the number of dead cockroaches/50 x 100%
The surface-dried tile was subjected to the effect test as day 1 and compared with the test effect after standing for 30 days and 180 days, respectively.
The cockroach-preventing agent prepared in examples 1 to 7 has a remarkable cockroach-preventing and cockroach-repelling effect, and still has a good cockroach-preventing effect when tested after 30 days and 180 days, and detailed results are shown in table 1.

The different components are adopted in the embodiment 1 and the embodiment 2, but the using effect is still good. The tile of example 5 maintained a kill effect similar to that of day 1 after being left for 180 days. 3.0 g of antifouling agent and 8.0 g of montmorillonite are added in example 7, the release of the cockroach repellent agent in the example is well controlled, the effect release is relatively uniform, and the antifouling performance of the example are optimal through actual tests. Compared with the example 3, the slow release filler in the example 8 is diatomite, and the difference is that the slow release filler in the example 8 is 13.0 g, and the slow release effect of the example 8 is more obvious, so that the slow release filler has a good slow release control function on the cockroach repelling effect. In example 9, only eucalyptus citriodora essential oil is used as a cockroach repellent, the source of the eucalyptus citriodora essential oil is more natural, the eucalyptus citriodora essential oil is more friendly to the human body and the natural environment, and the effect is not better than that of a pyrethroid type medicament in view of results, but the cockroach repellent effect is also more than 80% provided, and the essential oil type cockroach repellent formula is suitable for being applied to tiles paved in children rooms. In the example 10, transfluthrin and citronella essential oil are mixed, the transfluthrin and citronella essential oil show good synergistic effect, and the short-term and half-year cockroach repelling effect is obvious. Comparative example 1 only used 0.2% of transfluthrin, and the killing effect on cockroaches was not significant. Compared with the prior art, the cockroach repellent ceramic tile only contains 0.5% of dodecyl alcohol ester emulsifier, the prepared cockroach repellent is poor in stability, the emulsion is easy to stratify, the cockroach repellent effect of the prepared cockroach repellent ceramic tile is large in deviation, and the cockroach repellent drug-loaded ceramic tile is easy to precipitate on the surface of the cockroach repellent ceramic tile. Comparative example 3 in which a slow-release filler exceeding the range defined in the present application was added, the volatilization of pyrethroid was greatly affected, resulting in poor cockroach-repelling effect of the tile sample. In the comparative example 4, no slow-release filler is added, and after the prepared long-acting cockroach preventing agent is placed for 12 hours, a small amount of light yellow liquid appears on the upper layer of the cockroach preventing agent, and the long-acting cockroach preventing agent is detected to be the tetramethrin. The surface of the ceramic tile sample prepared by the comparative example is difficult to completely dry, oily liquid is separated out, and the slow-release filler can greatly help the stability of the cockroach-preventing agent. In the comparative example 5, the porous polystyrene microspheres are added as the slow-release filler, and the porous polystyrene is a nonpolar porous material, so that the adsorption effect on cockroach repelling medicine is strong, and the effective slow-release effect is difficult to realize.
