Problems solved by technology

In most studies, filler modification mainly relies on physical or hydrogen bonding between the modified material and calcium carbonate. Since this combination is not very strong, its application effect is reduced.

Embodiment 1

[0046] Step 1: Add 1.25% (relative to the amount of PCC added) squat gum into the three-hole oblique mouth containing 90g of water, raise the temperature to 80°C, stir and disperse at 400rpm, and then add 10g of precipitated calcium carbonate;

[0047] Step 2: Add 0.5% (relative to the amount of PCC) bistriethanolamine diisopropyl titanate into the reactor, and stir for 75 minutes;

[0048] Step 3: collecting the reaction product by centrifugation and washing and drying it;

[0049] Step 4: Grind the modified precipitated calcium carbonate and the precipitated calcium carbonate finely with a mortar, pass through a 200-mesh copper mesh, analyze and characterize them with a scanning electron microscope, Fourier transform infrared spectrometer, elemental analyzer, etc. respectively.

[0050] The Magna IR 560 Fourier Transform Infrared Spectrometer produced by Nicolet Company of the United States was used for measurement, and the scanning range was 400 to 4000 cm -1 , scanning sp...

Abstract

The invention provides sesbania gum organic titanium surface crosslinking modified precipitated calcium carbonate. Sesbania gum is in crosslinking to the surface of the modified precipitated calcium carbonate through organic titanium. The invention aims at providing the modified precipitated calcium carbonate which can obviously improve tensile index, burst index and tear index of paper when being applied to paper as filler and improve the filler one-pass retention. Meanwhile, the invention further provides a preparation method and application of the modified precipitated calcium carbonate. In addition, the invention further provides paper containing the modified precipitated calcium carbonate.

Description

technical field [0001] The invention relates to the field of modification of paper-making fillers, in particular to surface cross-linking modified precipitated calcium carbonate on the surface of selenium gum organotitanium, its preparation method, application and a kind of paper. Background technique [0002] At present, the most commonly used fillers in the paper industry are calcium carbonate, kaolin and talc, and these three types of fillers account for 80% to 90% of the total filler usage. [0003] Since the 1970s, as the production of high-grade paper changed from acidic to neutral or alkaline, calcium carbonate fillers gradually replaced kaolin and talcum powder fillers. In 2002, the domestic consumption of calcium carbonate fillers exceeded talcum powder for the first time. [0004] The surface electrical properties of calcium carbonate are closely related to its retention rate as a paper-making filler and the quality of filled paper. The crystal decomposition and re...
