Definitions
- the present invention relates to an ABS resin to which siloxanes or silsesquioxanes are bonded, and a flame-retardant ABS resin having a drip suppressing effect during thermal decomposition or combustion.
- ABS resins have excellent properties such as processability, dimensional stability, electrical properties, mechanical properties, and chemical stability, and are therefore used in transportation equipment, electrical and electronic equipment, housing equipment, general-purpose miscellaneous goods, and the like. Is used in a wide range of fields. However, the use of ABS resins is limited due to their flammability, and there are many application fields where flame retardancy is required to minimize damage in the event of a fire. A method of imparting flame retardancy due to a synergistic effect by adding a compound and diantimony trioxide has been adopted (for example, see Patent Document 1). However, the toxicity of the halogen-based gas generated during combustion has become a problem, and it has been desired to develop a flame-retardant method that does not generate any of these gases.
- Phosphate esters are known as non-halogen flame retardants to be added to ABS resin (for example, see Non-Patent Document 1), but their performance is still insufficient and phosphoric acid esters are not sufficient.
- the inherent hydrolyzability of esters has also been regarded as a problem in relation to the stability of fatty acid properties.
