ABS containing phosphogypsum modified with a novel silane coupling agent containing hindered phenol and a preparation method thereof

A technology of silane coupling agent and hindered phenol, which is applied in the field of modified ABS and its preparation, can solve the problem of not being able to suppress the breakage of polyene molecular chains, the difficulty of dispersing antioxidants and inorganic fillers, and the problems of antioxidants and inorganic fillers. Fillers are difficult to mix evenly, so as to reduce the surface energy, avoid uneven dispersion and reduce the process

Abstract

The invention discloses acrylonitrile-butadiene-styrene (ABS) containing phosphogypsum modified with a novel silane coupling agent containing hindered phenol. The ABS is characterized in that 0.1-1 part by mass of the novel silane coupling agent having a hindered phenol structure is added into 30-40 parts by mass of phosphogypsum, the mixture is stirred at a high speed at 60-80 DEG C for 20-30 min, then 100 parts of ABS is added into the mixture, and the mixture is stirred for another 30 min and is extruded by a twin-screw extruder to obtain the ABS containing phosphogypsum modified with the novel silane coupling agent containing hindered phenol.

Description

Technical field

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

[0002] ABS plastic is a terpolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S). The relative content of the three monomers can be changed at will to make various resins. ABS has the common properties of three components. A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, and S makes it have the processing and molding characteristics of thermoplastics and improve electrical properties . ABS plastic is a kind of "tough, hard and rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price and wide range of uses. ABS, as a common injection moldable thermoplastic, can be used to make L...
