The present invention relates to the technical field of household supply materials, and in particular, to an antibacterial bactericidal negative-ion releasing washable cushion and a preparation method therefor. The present invention is prepared from a high-molecular resin, an antioxidant, an antibacterial bactericide, an insect repellent, and a home-made negative-ion masterbatch. In the case that a mattress (cushion) added with the home-made insect repellent and the home-made negative-ion masterbatch maintains the physical performance unchanged and even improved, continuous and effective insect repelling and the release of negative ions good for the human body for more than 10 years can be implemented, and 1,000 or more negative ions can be released per cubic centimeter. |
