Phosphide-free household automatic dishwasher detergent and preparation method thereof

Abstract

The invention discloses a phosphide-free household automatic dishwasher detergent and a preparation method thereof, and the phosphide-free household automatic dishwasher detergent comprises the following raw material components by weight: 2-10% of a chelating agent, 15-45% of an alkali source providing agent, 1.0-5.0% of a nonionic surfactant, 5.0-15.0% of a suspended dispersant; 5.0-20.0% of an oxidation bleaching agent, 0.1-5.0% of an activator, 10-50% of a filling agent, 0.1-0.3% of essence and 0.1-5.0% of other auxiliaries. The phosphide-free household automatic dishwasher detergent is not added with a phosphide, can maintain good detergency, and at the same time can reduce the pollution of water bodies; the selected new chelating agent component is safe to use, no substance harmful to human body is produced, biodegradability is good, the detergent is energy-saving and environmentally-friendly, can be used in home life, and has a good application prospect.

Description

technical field [0001] The invention relates to a household automatic dishwasher detergent, which belongs to the technical field of daily chemical products. Specifically, the invention relates to a household automatic dishwasher detergent without phosphide and a preparation method thereof. Background technique [0002] The dishwasher cleans and removes the dirt on the tableware mainly by virtue of the spray effect generated by the strong water flow in the three-dimensional space, the thermal energy effect of the heated water, and the degreasing and decontamination effect of the cleaning agent. These three effects are coordinated with each other. After being pressurized by the booster pump, the water sprayed from the nozzle into the dishwasher performs a three-dimensional rotational movement in the machine. There is no dead angle in the machine that cannot be cleaned. The powerful water flow energy impact effect generated by the spray, It can effectively remove the dirt adher...
