Research and analysis method for improving odor and VOC of automobile material

Abstract

The invention discloses a research and analysis method for improving odor and VOC of an automobile material. The method comprises the following steps: 1, capturing and analyzing the type and the source of generated odor; 2, after the type and the source of the odor are determined, analyzing the product components in a product formula, analyzing the influence of the product components in the product formula on the odor, performing odor analysis on the single product component, and optimizing the formula; and 3, after formula optimization is completed, analyzing gas component changes caused by sample decomposition or volatilization, analyzing the temperature section capable of making the raw materials volatilize harmful substances, and guiding an injection molding process for a user. According to the method disclosed by the invention, GC-MS-O, FT-IR and TGA-IR analysis methods are combined, and odor and VOC are analyzed, researched and improved from the aspects of an odor source, a product formula, a technological process, a material processing finished product member and the like, so that the problem of odor / VOC of the automobile material can be rapidly and effectively improved, theresearch and development cost is reduced, the research and development time is shortened, the direction is pointed out for research and development, and the blank of research and analysis of odor / VOCof the automobile material is filled.

Description

technical field [0001] The invention belongs to the field of automobile materials, in particular to a research and analysis method for improving the odor and VOC of automobile materials. Background technique [0002] With the development of society, cars have been widely popularized. With the popularization of cars, the research on pollutants in cars and the air quality in cars has been paid more and more attention. Volatile Organic Compounds and Aldehydes and Ketones Sampling and Determination Method" standard document, and in 2011, GB / T 27630 "Guidelines for Air Quality Evaluation in Passenger Cars" recommended standard was launched. As a result, my country's automobile industry has gradually carried out research on pollutants in the car and research on control methods for air quality in the car. [0003] The research direction of pollutants in the car mainly includes the study of VOC compliance in the car, the improvement of the smell in the car, the principle and purifi...

AI Technical Summary

Problems solved by technology

However, the current detection and analysis methods for automotive materials all refer to HJ / T 400-2007. After the test, the indicators can only judge whether the automotive material is qualified, but the automotive material is modified by blending a variety of basic raw materials and additives. produced

For automotive material suppliers, it is difficult to meet the requirements for improving odor / VOC if only testing and judging the finished products of automotive materials

Nor can it provide guidance for the development of materials

R&D engineers can only adjust formulas and processes based on experience, resulting in long R&D cycles and great difficulties
