Chlorinated disinfectant and preparation method

The invention discloses a chlorinated disinfectant and a preparation method. The chlorinated disinfectant is prepared from the following raw materials: 1.5-3% of parachlorometaxylenol PCMX, 2.8-6% ofpolyhexamethylene guanidine, 1-2.2% of a surfactant, 1.2-2.8% of a stabilizer, 2-4% of an addition agent and the balance of deionized water. The preparation method of the chlorinated disinfectant comprises the steps that firstly the addition agent and the parachlorometaxylenol PCMX are added into a container, stirring and mixing uniformly are carried out at room temperature, and a mixture A is obtained; then the surfactant, the stabilizer and the deionized water are added into the mixture A, warming is carried out to 30-38 DEG C for stirring and mixing uniformly, and a mixture B is obtained; and finally, the polyhexamethylene guanidine is added into the mixture B, stirring and mixing uniformly are carried out, cooling is carried out to the room temperature, and filing is carried out to obtain the chlorinated disin
