Embodiment 1

[0012] Example 1: A sizing enhancer contains the following raw materials in parts by weight: 50 parts of ferrous sulfate, 5 parts of cationic active agent, 4 parts of bentonite, 5 parts of enhancer, and 1 part of starch. The preparation method is as follows: Step 1. The ratio of the raw materials in parts by weight of the glue enhancer, first dry the mixture of ferrous sulfate and the enhancer naturally;

[0013] Step 2: Mix the cationic active agent, bentonite, and starch;

[0014] Step 3: Add the materials of step 1 and step 2 to the mixer and mix them together, and inspect them after they are uniform;

[0015] Step 4. After being qualified, use an automatic packaging machine to pack and store in woven bags according to standard specifications.

Embodiment 2

[0017] A sizing enhancer contains the following raw materials in parts by weight: 12 parts of ferrous sulfate, 12 parts of cationic active agent, 15 parts of bentonite, 40 parts of reinforcing agent, and 5 parts of starch. The preparation method is as follows: Step 1. According to the sizing enhancer The proportion of raw materials in parts by weight of, first dry the mixture of ferrous sulfate and enhancer naturally;

[0018] Step 2: Mix the cationic active agent, bentonite, and starch;

[0019] Step 3: Add the materials of step 1 and step 2 to the mixer and mix them together, and inspect them after they are uniform;

[0020] Step 4. After being qualified, use an automatic packaging machine to pack and store in woven bags according to standard specifications.

[0021] The sizing enhancer obtained in the above example 1-2 was tested with corrugated base paper as the object to detect its application effect;

Abstract

The invention discloses a sizing reinforcing agent, which is prepared from the following raw materials in parts by weight: 50 to 60 parts of ferrous sulfate, 5 to 8 parts of cationic active agent, 4 to 8 parts of bentonite, 5 to 10 parts of reinforcing agent and 1 to 5 parts of starch. The reinforcing agent is prepared by gelatinizing a cationic material and starch together; the production methodis simple and convenient, aluminum sulfate is omitted, corrosion of the aluminum sulfate to a pipeline and a sizing roller is reduced, the sizing cost is greatly reduced, the ring crush compression strength of the double-side offset paper is improved, and the double-side offset paper has excellent water resistance and is widely suitable for paper types such as high-strength double-side offset paper and box paperboards suitable for surface sizing.

Description

Technical field [0001] The invention relates to a sizing enhancer, belonging to the technical field of papermaking. Background technique [0002] Sizing enhancers are used in the paper industry. With the rapid development of society and technology, and increasingly mature, higher requirements are put forward on the performance of paper. If you need to have good water resistance, high dry and wet strength, strong printing adaptability, high surface strength and so on. The commonly used AKD sizing agent, styrene acrylic sizing agent, synthetic surface sizing agent and other products on the market can no longer meet this requirement. Summary of the invention [0003] In view of the above problems, the technical problem to be solved by the present invention is to provide a sizing enhancer. [0004] A sizing enhancer of the present invention contains the following raw materials by weight: 50-60 parts of ferrous sulfate, 5-8 parts of cationic active agent, 4-8 parts of bentonite, 5-10 p...
