AI Technical Summary
Existing refrigerator door seal materials are prone to sticking and oil stains in high temperature and high humidity environments, affecting sealing performance and service life.
High-polymer polyvinyl chloride resin and oxidized polyethylene wax are used as functional lubricants, along with calcium-zinc stabilizers, plasticizers, and external lubricants. By adding plasticizers in stages and undergoing gentle heating and aging treatment, a thin film isolation layer is formed to prevent plasticizer migration and improve plasticization problems.
It effectively prevents plasticizer leaching, reduces the risk of adhesion between the door seal and the enclosure, improves surface oil staining, and enhances the anti-adhesion and anti-oil staining performance of the door seal material.
