Additive for cold-rolled continuous annealing strip steel degreasing agent and degreasing agent thereof

The additive is prepared from the following raw materials: cardanol polyoxyethylene ether, decyl glucoside APG, non-phosphorus organic amine ester TPP, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate, sodium dodecyl benzene sulfonate and sodium dodecyl benzene sulfonate. The cardanol polyoxyethylene ether, the decyl glucoside APG and the non-phosphorus organic amine ester TPP account for less than or equal to 5 parts by weight in the degreasing agent component, and the weight of the cardanol polyoxyethylene ether, the decyl glucoside APG and the non-phosphorus organic amine ester TPP is not zero at the same time. The cleaning agent is non-toxic, harmless and non-irritant to human bodies, pollution-free to the environment, capable of achieving low-temperature cleaning, high in cleaning rate, wide in adaptability, capable of
