Abstract:

Flame retardant is one of the important auxiliary agents for the synthesis of polymeric materials, which is also widely applied to electronical, chemical industry, aerospace, and so on. Based on the online patent analysis system of the Chinese academy of sciences, the patents in the field of flame retardants in China are statistically analyzed, including general status, application trend, area distribution, applicant and inventors. The present situation and development state of the flame retardant in our country is revealed. The results show that the technology of flame retardant starts earlier and develops to the rapid stage after entering 21th in China. As of 2016, the proportion of Chinese applicants accounts for 89% in China, of which Jiangsu has 3353 patents, accounting for 23% of the total number of patents in China. The researches of flame retardants are focused on the development of ingredients, such as the use of organic ingredients, the use of inorganic ingredients and the use of other large groups of ingredients mixture research.

Key words: flame retardant, patent, bibliometric analysis, development state
