Problems solved by technology

Among them, the basic components of self-luminous luminous materials are radioactive materials, which do not need to absorb energy from the outside and can continue to emit light. The radioactivity may cause certain harm to the human body (depending on the composition), so the application is relatively limited.

Abstract

The invention relates to a novel luminescent composite material. EuCl3 and trimethylsilanolate silicate ester are mixed for 2 hours to obtain a mixture; thioacetamide and ceramic powder are sequentially added into the mixture; the materials are stirred for 4 hours; then, palmitic acid and n-butyllithium are added; the materials are stirred for 2 hours at 80 DEG C; next, cyanoethyl chitosan and grapheme are added, and are stirred for 1 hour at 120 DEG C; finally, acrylic ester- styrol copolymers and N-formyl morpholine are added; the materials are stirred for 4 hours at 130 DEG C to obtain luminescent compounds; then, the luminescent components are added into a mold and is subjected to molding pressing to obtain the novel luminescent composite material. A preparing method disclosed by the invention has the advantages that the raw material resources are wide, the preparing process is simple and controllable, only conventional operation is needed, and the industrialization is easily realized.

Description

technical field [0001] The invention belongs to the technical field of novel composite materials, and in particular relates to a novel luminous composite material. Background technique [0002] Since the beginning of the 21st century, the global composite material market has grown rapidly, especially in Asia, especially in China. From 2003 to 2008, China's average annual growth rate was 15%, India's was 9.5%, while Europe and North America's average annual growth rate was only 4%. It is an important basic material for high-tech fields such as information technology, biotechnology, and energy technology and national defense construction. It also plays a very important role in transforming traditional industries such as agriculture, chemicals, and building materials. There are many kinds of composite materials and they are widely used. Among them, luminous composite materials are forming a large-scale high-tech industrial group, which has very broad market prospects and extre...
