Abstract

The invention relates to a process for preparing C9 petroleum coal resin suitable for pasting in paper-making industry by utilizing C9 fraction of petroleum, which comprises subjecting C9 petroleum fraction to vacuum distillation under the pressure of 0.08-0.09MPa, collecting 90-120 deg C C9 fraction as raw material of the reaction, charging 2-10% of maleio anhydride, 89-97% of C9 fraction and 0.2-1% of BF3-ether complex compound, reacting 3-5 hours at 50-80 deg. C, washing the polymerization liquid with NaOH and water to neutral, finally subjecting the polymerization liquid to vacuum distillation under the vacuum degree of 0.08-0.095MPa.

Description

technical field [0001] The present invention relates to a method using C 9 Petroleum distillate preparation suitable for C used for paper sizing in paper industry 9 Preparation method of solid petroleum resin. Background technique [0002] At present, developed countries in the world produce C 9 The trend of petroleum resin is developing in the direction of large-scale, diversified varieties and serialized grades. In contrast, my country's petroleum resin industry is still in its infancy. Due to the unstable raw material supply of petroleum resin, the lack of necessary separation and refining means for mixed distillates, and the relatively backward production technology, the resin has a darker color and poor stability, which greatly limits its application range. Most of the devices are small in scale, single in variety, and low in product quality, especially the main quality indicators such as product chroma and softening point are not stable, and many devices are in a s...
