Biodegradable compound toilet article and preparation method thereof

The invention belongs to the technical field of compound degradation processes, and particularly relates to a biodegradable compound toilet article and a preparation method thereof.The compound toilet article is prepared from, by weight, 40-50 parts of aliphatic diacid diol polyester, 50-60 parts of modified plant fiber, 10-20 parts of plant starch, 20-30 parts of polylactic resin and 5-10 parts of antibacterial agent. The preparation method comprises the following steps: treating the raw materials, mixing the raw materials, cooling the raw materials, extruding the raw materials, carrying out hot press molding, and cooling and polishing. The modified plant fibers and the modified plant starch are used as the main raw materials, so that the degradation rate of the toilet articles is increased; the prepared toilet article has certain mechanical strength and structural performance while having a degradable function, and the antibacterial agent is added into the toilet article, so that bacterium breeding can be e
