Styrene-acrylic copolymer resin with good low-temperature fixation and preparation method thereof

Abstract

The invention relates to styrene-acrylic copolymer resin with good low-temperature fixation and a preparation method thereof; the styrene-acrylic copolymer resin with good low-temperature fixation isprepared from the following raw materials in parts by weight: 10-80 parts of polymer intermediate resin A, 20-70 parts of copolymer intermediate resin B and 1-10 parts of a copolymer resin intermediate C. According to the invention, a compound containing two double bonds is used as a molecular weight regulator, so that Ts is properly reduced and the low-temperature photographic fixing performanceis improved on the premise of keeping Tg and good electrical properties of styrene-acrylic copolymer resin; a solution polymerization mode is used, so that the styrene-acrylic copolymer resin is safe,reliable and stable in quality; the finished product is solid powder, is convenient to store and transport and cannot form hazardous wastes; compared with conventional styrene-acrylic resin, the carbon powder prepared from the resin has obvious advantages in the aspect of low-temperature fixation.

Description

technical field [0001] The invention relates to the field of carbon powder resins, in particular to a styrene-acrylic copolymer resin with good low-temperature fixing and a manufacturing method thereof. Background technique [0002] In the prior art, a considerable part of the toner resin used in printers and copiers is styrene-acrylic copolymer resin, but in view of the structural characteristics of styrene-acrylic copolymer resin, at a relatively suitable glass transition temperature (Tg), its softening The dot (Ts) is also relatively high, thereby performing poorly in low-temperature fixing, and also limiting the application of styrene-acrylic copolymer resins in high-speed printers and copiers. Therefore be badly in need of a kind of can effectively guarantee safe and reliable, stable quality, the good styrene-acrylic copolymer resin of good low-temperature fixing of performance and manufacture method thereof. Contents of the invention [0003] The problem to be solve...
