Abstract

The invention discloses a polar small monomer modified sulfonic benzene ring core-shell emulsion polymer preparation method. According to the method, a sulfonic strong hydrophilic monomer and a benzene ring hydrophobic monomer are used as raw materials, and in an emulsion reaction system, the high-molecular polymer waterproof coating material is prepared by a series of processes such as emulsification reaction, constant-temperature polymerization, pH adjustment and the like, wherein the sulfonic intramolecular hydrogen bonds enhance the internal binding force of the polymer, and the strong hydrophilic effect enhances the adhesive force with the matrix, so that the tensile strength of a coating film is effectively improved by reasonably adding the polar small monomer, and the excellent emulsion polymer with good stability, strong adhesive force, good permeability resistance and lasting waterproof effect is prepared by combining with the partial refining process; and the emulsion polymerof the invention has high glass transition temperature and low film forming temperature so as to ensure the good film forming property.

Description

technical field [0001] The invention belongs to the technical field of fluorine-containing polymer emulsion. The polymer is prepared by three-part emulsion polymerization, relates to surfactant treatment technology, and is specifically a sulfonic acid benzene ring modified by a small polar monomer Preparation method of core-shell emulsion polymer. Background technique [0002] Bonding is an essential process in our daily life, and various compositions are known to be used as treatment agents to provide surface effects to substrates to achieve desired bonding effects. Surface effects include water repellency, soil repellency and stain repellency, among other effects, which are especially applicable to fibrous substrates such as fibres, fabrics, textiles, carpets, paper, leather, and other such substrates. Many of these treatments are fluorinated polymers or copolymers. Fluorinated polymer compositions useful as fibrous substrate treatments typically contain pendant perfluor...
