Abstract

The invention relates to a novel flame-retardant composite solid material which is reasonable in composition and high in compatibility among components; therefore, the prepared novel flame-retardant composite solid material is better in mechanical property, adhesive property and heat resistance, especially excellent in flame retardation, and can meet demands in development and application of novel flame-retardant composite solid material; a preparation method disclosed by the invention is wide in raw material sources, simple and controllable in preparation process; only normal operations are required, and industrialization can be achieved easily.

Description

technical field [0001] The invention belongs to the technical field of novel composite materials, and in particular relates to a novel flame-retardant composite solid material. Background technique [0002] The development and development of solid glue sticks first began abroad, and have a history of more than 70 years. The initial development of solid glue sticks is the solidification of liquid adhesives, which means that the adhesives can be used in solid form. With the continuous deepening and development of research, the adhesive used for bonding is also constantly updated. After decades of development, the research and application technology of foreign solid glue sticks has been relatively mature, and some companies have supplied solid glue products of various brands. [0003] The so-called macromolecule usually refers to a macromolecular compound composed of tens of millions of small molecular compounds connected by chemical bonds. General-purpose polymer material...
