| description | The invention discloses weather-resistant epoxy glue. The epoxy glue is prepared by mixing an epoxy resin main agent A and a curing agent B. The piperidylamine structure of a weather-resistant piperidylamine type light stabilizer is introduced into the epoxy structure of the main agent A with a chemical grafting method, the component A and the component B are mixed and cured, and an epoxy resin system with permanent weather resistance is formed. The manner that the light stabilizer is linked with the chemical method is more stable, migration of the micromolecular light stabilizer in the epoxy system can be substantially reduced, so that the weather resistance of a product can be improved, and the service life can be prolonged; in particular, the epoxy glue is applied to the food packaging field with higher requirements for weather resistance and micromolecule migration, the migration of the light stabilizer in the product is substantially reduced by the aid of the chemical grafting scheme, thus, the safety of food is improved, and human health is better guaranteed. |
