Polyolefin containing hindered phenol-structured novel silane coupling agent modified ardealite and preparation method of polyolefin

A technology of silane coupling agent and hindered phenol, which is applied in the field of modified polyolefin and its preparation, can solve the problems of not being able to suppress the breakage of polyolefin molecular chains, the difficulty of dispersing antioxidants and inorganic fillers, and the problems of antioxidants and inorganic fillers. Inorganic fillers are difficult to mix evenly, so as to achieve the effect of reducing surface energy, avoiding uneven dispersion and reducing the process

Description

technical field

[0001] The invention relates to a modified polyolefin and a preparation method thereof, in particular to a novel silane coupling agent-modified polyolefin containing hindered phenol and a preparation method thereof. Background technique

[0002] Polyolefin is a polymer compound formed by polyaddition reaction of olefin. Such organic polymers are usually polymerized from many identical or different simple olefins (such as polypropylene, polyethylene, etc.), and the molecular chains of polyolefin molecules exhibit significant non-polar phenomena. Phosphogypsum refers to the solid waste generated when sulfuric acid is used to treat phosphate rock in the production of phosphoric acid, and its main component is calcium sulfate. Phosphogypsum is an industrial waste with extremely low cost. Using phosphogypsum as a filler can significantly reduce the cost of polymers. However, since phosphogypsum is a polar molecule, adding phosphogypsum fillers will easily cause ...
