Abstract
A low-corrosion fire-resistant thermoplastic resin composition comprising a thermoplastic resin, a phosphinic acid salt flame retardant, a reinforced glass fiber, and a rare earth metal salt corrosion inhibitor. The resin composition improves the corrosion resistance and mechanical performance of the metal to a great extent while maintaining the high flame resistance.
Claims7
A low-corrosion flame-resistant thermoplastic resin composition consisting of
- a thermoplastic resin,
- a phosphinic acid salt,
- a reinforced glass fiber,
- a rare earth metal salt, and
- optionally, an auxiliary flame retardant,
- wherein the phosphinic acid salt is selected from the group consisting of an ammonium salt, an amine salt, an alkali metal salt, an alkali-earth metal salt, an aluminum salt, a zinc salt, and ferric salt, and the phosphinic acid salt is a hypophosphite, a bis-hypophosphite, a polymer of the phosphinic acid salt, or a polymer of the bis-hypophosphite;
- the rare earth metal salt is a phosphinic acid rare earth metal salt having a formula (1) or (2):
- R1 and R2 are each independently selected from a linear or branched C1-C8 alkyl or a phenyl;
- n is 3;
- R3 is selected from any of the linear or branched C1-C10 alkylidene, arylidene, alkyl arylidene, or aryl alkylene;
- and M is a rare earth metal, and
- the auxiliary flame retardant is selected from the group consisting of a melamine polyphosphate, ammonium polyphosphate, melamine ammonium phosphate, melamine ammonium polyphosphate, melamine ammonium pyrophosphate, a reaction product of melamine and phosphoric acid, and a mixture thereof.
