in comparative example 5, an easily degradable solid deodorant was composed of the following raw materials in parts by weight: 33 parts of bentonite, 25 parts of plant source bactericide particles, 17 parts of polyvinyl alcohol, 34 parts of 1, 3-butanediol, 6.5 parts of ferment, 2.2 parts of sodium lignosulfonate and 2.8 parts of citric acid.

Further, the plant source bactericide particles are prepared by the following steps: crushing the shaddock peel and the corncob, adding sweet orange oil, uniformly mixing, then placing into a high-temperature furnace for calcining at 350 ℃ for 45min, continuously introducing nitrogen gas during the calcining process, grinding into powder after the calcining is finished, immersing the powder into the plant source bactericide, performing ultrasonic dispersion for 15min, performing suction filtration to obtain powder loaded with the plant source bactericide, adding erucamide, and finally performing spray drying to obtain the plant source bactericide particles.

Furthermore, the mass ratio of the shaddock peel to the corncobs is 1:2, the mass ratio of the shaddock peel to the sweet orange oil is 1:0.3, and the mass ratio of the shaddock peel to the erucamide is 1: 0.2.

Furthermore, the shaddock peel and the corncobs are crushed and then screened, and the mesh number of the screen is 120 meshes.

Further, the botanical fungicide is at least two of sweet wormwood herb extract, stellera chamaejasme extract, garlic oil, tea tree oil, camphor oil, fructus kochiae extract and aloe extract.

Further, the polymerization degree of the polyvinyl alcohol is 300-3000.

Further, the preparation method of the easily degradable solid deodorant comprises the following steps:

s1, dispersing bentonite in deionized water, adding enzyme, sodium lignosulfonate and citric acid, stirring for 30-60min, quickly filtering after the stirring, and freeze-drying a filter cake;

s2, adding the filter cake after freeze-drying treatment into 1, 3-butanediol, adding plant source bactericide particles and polyvinyl alcohol, fully mixing, and performing extrusion molding after mixing to obtain the easily degradable solid deodorant.

Further, in the step S1, the mass ratio of bentonite to deionized water is 1: 7.

the performance of the easily degradable solid deodorant prepared in examples 1 to 5 and comparative examples 1 to 5 was tested as follows:

taking 11 sealed boxes (length multiplied by width multiplied by height is 1m multiplied by 1m) with the same size, vacuumizing the sealed boxes, and introducing the same amount of odorous gas (the volume concentration is 2% of ammonia gas, 10% of hydrogen sulfide, 3% of ethylamine and the balance of air);

the same amount of the easily degradable solid deodorant prepared in examples 1 to 5 and comparative examples 1 to 5 was placed in an outdoor environment for 48 hours, and then put into the corresponding sealed boxes, the same amount of the easily degradable solid deodorant prepared in comparative example 5 was put into the remaining sealed boxes directly, and the sealed boxes were recorded as comparative example 1, and then subjected to deodorization treatment at the same temperature (room temperature) for 24 hours, and finally, the odor gas components in each sealed box were detected, and the removal rate of the odor gas was calculated, and the results are shown in table 1.

TABLE 1

As can be seen from Table 1, the removal rate of the prepared easily degradable solid deodorant for harmful gases in the sealed box in examples 1-5 reached more than 95%, the shaddock peel and corncob were not added in comparative example 1, the removal rate of harmful gas is slightly reduced, the removal rate of harmful gas is slightly reduced without adding erucamide in the comparative example 3, in comparative example 2 no chitosan was added, in comparative example 4 no beta-cyclodextrin was added, in comparative example 5 no chitosan and no beta-cyclodextrin were added, wherein the removal rate of the harmful gas of comparative example 2 and comparative example 4 is inferior to that of comparative example 1, and the removal rate of the harmful gas of comparative example 5 has been less than 90%, with respect to comparative example 5, the deodorant of comparative example 1 was not placed in an outdoor environment, the removal rate of harmful gases is not much different from that of the examples 1-5, and is obviously better than that of the comparative example 5.
