Example Embodiment
[0012] Example 1
[0013] The components and weight percentages of the phosphorus-free scouring agent are as follows:
[0014] Isomeric C8 alcohol ether (6EO) carboxylate 15%, C8-10 alkyl glycoside 15%, isomeric C8-10 alcohol polyoxyethylene ether (3EO) 10%, deionized water 60%.
Example Embodiment
[0015] Example 2
[0016] The components and weight percentages of the phosphorus-free scouring agent are as follows:
[0017] Isomeric C10 alcohol ether (3EO) carboxylate 18%, C8-10 alkyl glycoside 14%, isomeric C10-12 alcohol polyoxyethylene ether (5EO) 8%, and deionized water 60%.
Example Embodiment
[0018] Example 3
[0019] The components and weight percentages of the phosphorus-free scouring agent are as follows:
[0020] Isomeric C13 alcohol ether (5EO) carboxylate 25%, C10-12 alkyl glycoside 10%, isomeric C13-15 alcohol polyoxyethylene ether (6EO) 5%, deionized water 60%.
[0021] The isomeric C8 alcohol ether (6EO) in the above Example 1 specifically refers to the product obtained by the addition of an isomeric C8 alcohol and 6 EO (ethylene oxide), and other similar expressions also refer to this meaning.
[0022] The preparation methods of the phosphorus-free scouring agent of the above three embodiments are:
[0023] Put the isomeric alcohol ether carboxylate, alkyl glycoside, isomeric alcohol polyoxyethylene ether and deionized water into the reactor according to the formula ratio, and stir and mix for 20-40 minutes under normal pressure and within the range of 40-50℃ , Cool, filter and package to get the product.
