Then, palmitic acid, fatty alcohol polyoxyethylene ether, white oil, and sodium dodecylbenzene sulfonate are added, and the mixture is ball milled again at a ball milling speed of 142-151 rpm, a ball milling time of 21-27 min, and a ball milling temperature of 10-14°C. After the process, the mixture is dried to obtain the functional agent. The OSB board prepared by this invention exhibits good antibacterial and antifungal properties, maintaining excellent antibacterial and antifungal performance even in high-temperature, humid environments and environments with a moisture content of up to 30%.

The invention discloses a compound phenol disinfectant and a preparation method thereof. The compound phenol disinfectant comprises the following components: crude phenol, dodecylbenzene sulfonic acid, acetic acid, phosphoric acid and water, wherein the mass percent of the crude phenol is 40-50%, the mass percent of the dodecylbenzene sulfonic acid is 15-22%, the mass percent of the acetic acid is 22-26%, the mass percent of the phosphoric acid is 2-8%, and the balance is water. The dodecylbenzene sulfonic acid and the phosphoric acid are added into the compound phenol disinfectant, so that the stability, the dispersity and the water solubility of the compound phenol disinfectant can be effectively improved, the compound phenol disinfectant is not easy to oxidize and deteriorate, the storage time is prolonged, and the sterilization and disinfection strength and the broad-spectrum property of the disinfectant can be further improved.
