Whether it is latex paint or oil-based paint, to achieve excellent anti-mold effect, anti-mold agent is essential. DL-M80 has superior stability in dried paint film.













The polymerization inhibition constant C2 can be used to characterize the polymerization inhibition ability of the polymerization inhibitor. The polymerization inhibition constant Cz of some commonly used polymerization inhibitors is listed in Table 4-12. It can be seen from Table 4-12 that the C2 value changes with the types of monomers and polymerization inhibitors, that is, olefins with different structures require different types of polymerization inhibitors, and olefins with the same structure are used in the production process, montan wax melting point storage and transportation process. The requirements for polymerization inhibitors are also different. Therefore, there are many different types of polymerization inhibitors.

According to the molecular structure, it can be divided into two types: radical type and molecular type. Molecular type polymerization inhibitors can be divided into two types: organic and inorganic. In actual production and scientific research, polymerization inhibitors are often divided into 9 categories according to the types of substituents: ① Free radical type, such as 1,1-diphenyl-2-picrylhydrazine, triphenylmethyl radical, oxygen Free radicals, molecular oxygen; ②polyphenols, such as hydroquinone, p-tert-butylcatechol, 2,5-di-tert-amyl hydroquinone; ③aromatic amines, such as methylaniline and benzidine; ④quinones, such as tetrachlorobenzoquinone, p-benzoquinone, anthraquinone; ⑤nitro compounds, such as 2,4-dinitrotoluene and m-dinitrobenzene; ⑥nitroso compounds, such as N-nitroso Diphenylamine, nitrosobenzene and nitroso-β+ naphthol; ⑦organic sulfides, such as sulfinyl diphenylamine and dithiobenzoyl disulfide; ⑧inorganic compounds, such as ferric chloride, trichloride Titanium and cuprous chloride; ⑨ elements, such as sulfur and copper powder.
