This paper discusses the latex type and monomer proportional analysis method in architectural coatings.It is analyzed with FTIR,and the type of latex is judged by the position of the characteristic absorption peak contained in the sample,such as the position of the benzene ring single-substituted characteristic absorption peak,the position of Si—C or Si—O.In addition,some unknown latex types can also be confirmed with Py-GC/MS,and the peak retention time and area of the monomer can also be used to analyze the synthetic monomer qualitatively and quantitatively.
