Embodiment Construction

[0017] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0018] The present invention provides a kind of analysis method of the precipitation of automobile rubber sealing strip, comprising the following steps:

[0019] S1. Use acetone solution to sample the frosted and non-sprayed areas of the car at the same time, and analyze the samples by pyrolysis gas chromatography / mass spectrometry (Py-GC / MS). The temperature of the cracker is 300°C, and the carrier gas is helium. The heating rate of 10°C / min is raised from room temperature to 300°C, and the spectrum is compared with the standard sample to obtain the information of the complexing agent or cracked product;

[0020] S2. Take a sample of the sealing strip that has the problem of blooming, and divide it horizontally into an upper part and a lower part,

[0021] S21. Put ...

Abstract

The invention provides an automobile rubber sealing strip precipitate analysis method. According to the method, a Py-GC-MS, a simulation test and a contamination test are adopted to analyze the automobile rubber sealing strip precipitates, so that the analysis result is more correct and basis is provided for the adjustment of the sealing strip rubber formula, thereby solving the blooming problem of the automobile rubber sealing strips.

Description

technical field [0001] The invention relates to the technical field of sealing strips, in particular to a method for analyzing precipitates of automobile rubber sealing strips. Background technique [0002] Automotive rubber seals are one of the important parts of automobiles, widely used in doors, windows, body, seats, sunroofs, engine boxes and trunk lights, etc., with waterproof, sealing, sound insulation, dustproof, antifreeze, light Vibration, warmth and energy saving. Automotive rubber sealing strips are easy to install, firm and reliable, but frosting problems may occur during use. Due to the different formulations of rubber materials, the blooming problems of different rubber sealing strips are also very different, which brings great difficulty to solve the problem of blooming of rubber sealing strips. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and proposes the analysis method of the...
