| titleOfInvention | A kind of preparation method of APP/kaolin composite flame-retardant agent |
| abstract | The present invention discloses a kind of preparation method of APP/kaolin composite flame-retardant agent, and concrete technology step is：(1) ultra-fine water-washed kaoline is calcined into 1~2h at 600~900 DEG C, obtains calcined kaolin；(2) surface modification, 100~250 DEG C, 1~2h of modification time of modification temperature are carried out to APP with melamine, the dosage of melamine is the 5%~25% of APP quality, obtains ammonium polyphosphate modifying；(3) by calcined kaolin and ammonium polyphosphate modifying in mass ratio 1:2~6 are mixed, then duplex surface modification, 60~120 DEG C of modification temperature, 15~60min of modification time are carried out using modifying agent, the dosage of modifying agent is the 0.5%~3% of calcined kaolin and ammonium polyphosphate modifying gross mass, obtains APP/kaolin composite flame-retardant agent.The present invention can significantly reduce the water solubility and hygroscopicity of APP, lift the impervious analysis performance of APP filled high polymer material product. |
