Study On The Analysis Of Several Complex Plastic Additives

Fetching in advanced technology of home and abroad is an important way for accelerating development of our country. The analysis for overseas new product is one of the important quarries for bringing in overseas advanced technology and that is one of ways for gaining firsthand overseas advanced technology data. It is difficulty that discovering the composing and rate of overseas new product in commonly literatures even patent. In a sense, the analysis is scout for high-speed development of China's industrial materials and expanding the application of material.In this paper, all-around analyses of several plastic additives (surface modifiers; inorganic filler; ACR et al.) have been completed, and quantitative analyses of the major components also have been completed.1. The separation and the analytical process for clarifieation of the composition of an unknown surface modification additive was reported in this paper; Qualitative analysis and quantitative analysis of the surface modification additive were completed by using infrared spectrometry and GC-MS. A unknow surface modification additive was solved by n-hexane and chloroform, and separation was completed by using filtration. The filtrate was determined by GC-MS with HP-5MS capillary column in the scan monitoring mode. Column temperature gradient: initial temperature 70℃, and then increased at 20℃/ min to 260℃, and maintain 40min. SCN is collection method. We calculated the relative amount of these compounds by using peak area normalization method. According to the experimental data, the liquid part contains 22 organic compounds. The content of palm acid is the highest, next stearic acid. The residue was determined by infrared spectrometry and the component is oxidation polyethylene. Through quantitative analysis, we can see that the content of oxidation polyethylene is 53.6%. The content of palm acid is 22.5%, and the content of stearic acid is 10.5%.2. In this study, the separation and the analytical process for the activation inorganic filler have been completed, and the size of particle has been tested. We completed the all-around analyses of the inorganic filler by using infrared spectroscopy, GC-MS, ICP-MS and particle size analyzer. Its main ingredient is silica. Component of surface modification is titanium aluminum compound coupling agent. The average particle size of inorganic filler is 21.09μm, in which 10μm-30μm is about 62%3. In this study, the separation and the analytical process for ACR have been completed. Infrared spectroscopy and GC-MS were used for completing the analysis of ACR. 12 kinds of compounds were identified, in which the inorganic filler is calcium carbonate and organic compounds is the main ingredient in fatty acid esters.
