Abstract

The invention discloses a polycarbonate modification material and a preparation method thereof. The polycarbonate modification material is prepared from the following raw materials in parts by mass:75to 90 parts of first polycarbonate, 10 to 25 parts of second siloxane copolymer polycarbonate, 10 to 30 parts of compositions, 0.005 to 0.04 part of hydrolysis resistant agents, 0.2 to 0.6 part of antioxidants, 0.2 to 0.6 part of light stabilizers, 0.2 to 0.5 part of UV agents, 6 to 20 parts of compatilizers and 0.5 to 5 parts of talcum powder, wherein the first polycarbonate is bisphenol A typelinear polycarbonate recovery crushing materials, and has the diameter of 2 to 4mm; under the conditions that the temperature is 300 DEG C and the weight is 1.2kg, the test melt mass flowing speed is14+ / -1g / 10min; the heat deformation temperature of the second siloxane copolymer polycarbonate is 120 to 128 DEG C; the composition is a mixture of any two kinds of materials in PBT, PSF and PCL. Thepolycarbonate waste materials can be recovered and utilized; the polycarbonate modification material with high mechanical intensity can be prepared; application can be expanded.

Description

technical field [0001] The invention relates to a preparation method of a modified material, in particular to a chemical-resistant and stable polycarbonate modified material and a preparation method thereof. Background technique [0002] Polycarbonate resin is an engineering plastic with excellent comprehensive properties, which has good transparency, good dimensional stability, high impact strength and good dielectric properties. In recent years, its demand has grown faster than other materials, and it has good applications in automobiles, electrical appliances, profiles, and optical instruments. However, due to its complex preparation process, it has been in short supply in recent years. In order to make rational use of resources, polycarbonate recycling is a very meaningful thing. But only recycling, without modification, can't play its value. Contents of the invention [0003] In order to solve the problem that polycarbonate waste materials cannot be recycled and ut...
