| titleOfInvention | Preparation method of fluorine-free waterproof agent and prepared fluorine-free waterproof agent |
| abstract | The invention discloses a preparation method of a fluorine-free waterproof agent and the prepared fluorine-free waterproof agent, belongs to the technical field of fabric waterproof finishing agents, and solves the problem of poor processing stability. The preparation method of the fluorine-free waterproof agent comprises the following steps: a: mixing an emulsifier a, ethanol a, water a and tetraethoxysilane to obtain a mixture X; b: mixing an emulsifier b, ethanol b, water b and methyl triethyl siloxane to obtain a mixture Y; c: mixing the mixture X and the mixture Y, and adding a silane coupling agent and chloroplatinic acid to obtain a mixture Z; d: mixing alkyl acrylate, hydroxyethyl acrylate or hydroxypropyl acrylate and an emulsifier c to obtain a mixture M; e: mixing the mixture M and an initiator V-50 to obtain a mixture N; f: mixing the mixture Z, the mixture N and the paraffin emulsion to obtain a mixture Q; and adding a pH regulator to obtain the fluorine-free waterproof agent, thereby improving the processing stability of the fluorine-free waterproof agent. |
