preparation example Construction

[0018] see figure 1 , figure 1 It is a flowchart of a preparation method of an anti-hydrocolloid provided in the embodiment of the present invention. As shown in the figure, the preparation method of the anti-hydrocolloid provided in the embodiment of the present invention includes:

[0019] S10: Carry out enzymatic digestion and cooking of starch, and control the linear part of the starch molecule after enzyme digestion and cooking to connect with α-D-1,4 glycosidic bonds, while the branched chains are connected with α-D-1,6 glycosidic bonds connected to the main chain.

[0020] The enzymatically digested and cooked starch described in the embodiments of the present invention refers to a high polymer polymerized by α-D-glucose.

[0021] In actual implementation, conventional starch raw materials can be selected, such as one or more combinations of raw tapioca starch, raw corn starch, and the like. Use high-temperature α-amylase and starch raw materials to mix and cook. Hi...

Embodiment 1

[0045] Starch: corn starch, 100 parts

[0046] Silicone: 3 parts

[0047] MFC: 0.7 parts

[0048] Surfactant: 0.4 parts

[0049] When raw corn starch is enzymatically digested and cooked, organic silicon is added, the cooking temperature is 120, and the temperature is kept at 90°C for 0.5h. During the heat preservation process, MFC and surfactant are added, stirred evenly, and sizing.

Embodiment 2

[0051] Starch: tapioca raw starch, 100 parts

[0052] Silicone: 5 parts

[0053] MFC: 1.2 parts

[0054] Surfactant: 1 part

[0055] When raw cassava starch is enzymatically cut and cooked, silicone is added, the cooking temperature is 130°C, and the temperature is kept at 90°C for 1 hour. During the heat preservation process, MFC and surfactant are added, stirred evenly, and sizing.

Abstract

The invention discloses a preparation method of water-resistant colloid and a coated paper. The preparation method of the water-resistant colloid comprises carrying out digestion stewing on starch, connecting a linear straight chain part of the starch molecule subjected to digestion stewing to a main chain by an alpha-D-1, 4 glycosidic bond and a branched chain to the main chain by an alpha-D-1, 6 glycosidic bond, adding organosilicon into the starch subjected to digestion stewing according to a ratio of the organosilicon amount to starch oven dry amount of 1-15%, and carrying out high-temperature stewing thermal insulation to obtain the water-resistant colloid. The surface of a paper is coated with the water-resistant colloid so that paper surface water resistance is greatly improved.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for preparing an anti-hydrocolloid and coated paper. Background technique [0002] With the improvement of living standards, people's demand for differentiated quality of paper is also increasing, mainly including high-grade cultural paper, food packaging paper, kraft paper, high-strength corrugated base paper, etc., among which there are some water-resistant papers that require high water resistance. For example, in the advertising business, special coated papers such as water-soaked label paper and indoor advertising paper are required to have surface waterproof or water-resistant functions. Printing companies often use imported waterproof coated paper to print these products. In recent years, there have been more and more studies and reports on different types of waterproof coated paper. Generally, it needs to be adjusted in various aspects such as refining, adding more wet...
