The present application relates to the technical field of artificial board, and discloses a kind of mould-proof composite board for wardrobe and a preparation method thereof.The composite board for wardrobe prepared by the present application is prepared by using rubberwood sheet as main raw material, impregnating treatment with mould-proof and antibacterial agent, and then adhesive treatment with adhesive containing mould-proof and antibacterial agent.The composite board realizes long-term inhibition of mould through multi-mechanism sterilization of components, synergistic effect and material level protection, and is suitable for wardrobe application in high-humidity environment.In addition, the use of mould-proof and antibacterial adhesive also endows the composite board with excellent bonding strength.

The present invention discloses a controlled-release type polymeric ferric sulfate water treatment agent and its preparation method, belonging to the technical field of water treatment functional materials. The water treatment agent consists of polymeric ferric sulfate, an iron ion color indicator, a gel matrix, a cross-linking calcium agent, amino diatomaceous earth, a pore-forming agent and an inert filler. The preparation method includes: first preparing a network gel, then preparing soft materials, and finally obtaining the product through pill-making and drying. The present invention realizes the slow release and controllability of polymeric ferric sulfate, and the color indicator can directly reflect the consumption state of polymeric ferric sulfate, facilitating storage, transportation, dosing and recovery.
