Phosphorus-free water-based degreasing agent suitable for low temperature and preparation method thereof

Abstract

The invention relates to the technical field of degreasing agents, in particular to a low-temperature applicable phosphorus-free water-based degreasing agent and a preparation method thereof. The invention relates to a phosphorus-free water-based degreasing agent applicable at low temperature, which is prepared from the following components in parts by weight: 1.5 to 3 parts of anhydrous sodium metasilicate, 2 to 5 parts of sodium carbonate, 0.01 to 0.1 part of sodium bicarbonate, 0.5 to 1.5 parts of polyethylene glycol octylphenol ether, 1 to 3 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 1 to 5 parts of fatty alcohol polyoxyethylene ether, 0.5 to 1 part of propylene glycol monomethyl ether and 0.1 to 0.6 part of sodium polyacrylate. The cleaning agent is prepared from the following components in parts by weight: 0.6-1.1 parts of an organic silicon defoaming agent, 0.1-1.5 parts of polyether modified silicone oil, 1-3 parts of ethylene diamine tetraacetic acid disodium salt and 20-60 parts of water.
