Example Embodiment

[0037] Example 1

[0038] An inorganic mineral fiber ring pressure-reinforced surface sizing agent for papermaking. The sizing agent is composed of surface sizing starch and composite mineral fiber. The composite mineral fiber accounts for 5% of the sizing agent by mass. The composite mineral fiber is wollastonite fiber and attapulgite clay with a mass ratio of 7:3.

[0039] The preparation method of the sizing agent is to mix the composite mineral fiber and the surface sizing starch to form an aqueous solution with a mass concentration of 8%, stir evenly, and raise the temperature to 90° C., gelatinize for 30 min, and lower the temperature to 60° C.

Example Embodiment

[0040] Example 2

[0041] The difference from Embodiment 1 is:

[0042] The composite mineral fiber accounts for 10% of the sizing agent by mass.

Example Embodiment

[0043] Example 3

[0044] The difference from Embodiment 1 is:

[0045] The composite mineral fiber accounts for 15% of the sizing agent by mass.

Abstract

The invention relates to an inorganic mineral fiber ring crush strength-improvement surface sizing agent for papermaking and a preparation method thereof. The inorganic mineral fiber ring crush strength-improvement surface sizing agent comprises surface sizing starch and inorganic mineral fibers. The mineral fibers comprise composite mineral fibers, modified wollastonite or wollastonite. The inorganic mineral fiber ring crush strength-improvement surface sizing agent comprises 5-40wt% of the inorganic mineral fibers. The norganic mineral fiber ring crush strength-improvement surface sizing agent can greatly improve corrugated paper ring crush strength and improve a tensile index and folding strength of a coated paper.

Description

technical field [0001] The invention relates to an inorganic mineral fiber ring pressure-reinforced surface sizing agent for papermaking and a preparation method thereof. Background technique [0002] At present, in order to reduce production costs, the domestic paper industry mostly uses waste paper to produce high-strength corrugated paper, but the most serious problem is that the ring crush strength is low, which cannot meet the requirements of customers. In order to find a solution, most enterprises producing high-strength corrugated paper adopted the surface sizing technology introduced from abroad in 2004 in order to solve this problem. But the current results are far from satisfactory. In recent years, the industry has made many technological innovations, including trying to add PVA to increase the ring pressure during the surface sizing process. Although the ring pressure has been improved to a certain extent, the high production cost has discouraged enterprises. T...
