Description

technical field [0001] The invention relates to the technical field of resin materials, in particular to an antibacterial and anti-corrosion resin material for automobile relay casings and a preparation method thereof. Background technique [0002] After curing, the thermosetting resin forms a network structure due to intermolecular crosslinking, so it has high rigidity, high hardness, high temperature resistance, non-flammability, and good dimensional stability of the product, but it is brittle. Therefore, before molding most thermosetting resins into products, various reinforcing materials, such as wood powder, mineral powder, fibers or textiles, are added to strengthen them to make reinforced plastics. In the thermosetting resin, adding reinforcing materials and other additives, such as curing agent, colorant, lubricant, etc., can be made into thermosetting plastics, some are powdery, granular, and some are made into lumps and flakes, collectively referred to as molding c...
