In summary, the following steps: the pressure-sensitive adhesive prepared by the invention selects special functional monomers and imported high-quality emulsifiers, adopts advanced pre-emulsification semi-continuous emulsion polymerization technology, and has the advantages of high content of prepared emulsion, few crystal points after coating, drying and film forming, high film surface transparency and no cracking.
The specific analysis is as follows:
the soft monomer has very low glass transition temperature and can endow the pressure-sensitive adhesive with bonding performance and flexibility;
the hard monomer has higher glass transition temperature, provides cohesive force and peel strength, and after being copolymerized with the soft monomer, the rigidity of a polymer molecular chain is improved, and the cohesive strength of the adhesive is higher. Therefore, according to different application requirements, the ratio of the soft monomer to the hard monomer is moderate, and the pressure-sensitive adhesive with good performance can be prepared so as to meet different use requirements.
The functional monomer is mainly used for carrying out crosslinking modification on a polymer to improve the water resistance, heat resistance, aging resistance, bonding strength, cohesive force and adhesive force of the polymer, the crosslinking method is to introduce a comonomer with a special crosslinking group in the emulsion polymerization process to ensure that the main chain of the emulsion polymer is provided with the crosslinking group, and in the later emulsion film forming process, a crosslinking bond is generated through the chemical reaction between the crosslinking groups on the molecular chain of the copolymer or the chemical reaction between the crosslinking groups on the main chain of the polymer and an external crosslinking agent under certain conditions to form the crosslinked polymer, for example: the epoxy type crosslinking monomer contains double bonds and epoxy groups, can participate in emulsion polymerization reaction, introduces the epoxy groups onto the main chain of the copolymer, and in the emulsion film-forming process, the epoxy groups can react with carboxyl, amino, hydroxyl and other groups on the main chain of the polymer or the added crosslinking agent molecules to produce crosslinking bonds, so that the linear emulsion polymer is changed into a molecular network structure, and the water resistance, the bonding strength and the heat resistance of the polymer emulsion are improved.
The crystal points in the existing protective film are mainly caused by unstable polymerization of high-solid emulsion and small aggregates which cannot be filtered out from the emulsion. And a pre-emulsification semi-continuous emulsion polymerization process is adopted, the polymerization reaction is stably carried out, few gel particles are generated in the polymerization reaction process, and the film surface crystal points can be greatly reduced in later application.
