Description
Technical Field
The invention belongs to the technical field of washing and caring liquid, and particularly relates to a hydrophilic zinc oxide-based bactericidal laundry detergent, a preparation method and application thereof.
Background
The laundry detergent is mild to skin, strong in dirt-removing power and small in environmental pollution, so that the laundry detergent is one of clothes cleaning products widely used by the public. In consideration of different practical applications, the main body of the laundry detergent on the market is different, and the main beating efficiency is different. Has the main effect of removing oil stains, and can kill bacteria, viruses and the like in some cases. At present, some multifunctional laundry detergents on the market are additionally provided with some surfactants or other additives on the basis of the original basic laundry detergent, so that the dirt-removing capacity is enhanced; meanwhile, some antibacterial agents are added, so that the antibacterial disinfectant has the antibacterial and disinfecting functions. In particular, the antibacterial agents in these antibacterial laundry detergents are generally chlorine-containing chemicals, and when the laundry contacts water, some antibacterial disinfection byproducts are inevitably generated, which have been recognized by the world health organization as having certain carcinogenicity. In order to avoid these problems, some novel antibacterial laundry detergents begin to add antibacterial nanoparticles, such as nano silver or silver nitrate, which utilize the excellent bactericidal properties of silver nanoparticles and silver ions, and do not generate toxic byproducts while killing pathogens. However, silver is expensive, and when the silver-based antibacterial agent is used for commercial laundry detergents, the industrial cost is increased due to the mass use of the silver-based antibacterial agent, and the price of corresponding products is greatly increased.
The zinc oxide nano-particles also have excellent antibacterial property, and can solve the problem that the traditional chlorine-containing disinfection preparation generates toxic byproducts while killing bacteria. Compared with silver-based antibacterial materials, the price of the antibacterial liquid laundry detergent is lower, so that the antibacterial liquid laundry detergent based on the zinc oxide nanoparticles provided by the invention has the effects of decontamination, sterilization and disinfection, and does not greatly increase the commodity price, thereby having great commercial application prospect and value.
