At present, the support tubes used to support the cloth roll, the wire roll, and the toilet paper roll roll are all made of multi-layered wrapping paper after being coated with adhesive and then rolled and dried. Adhesives used in this type of paper tube include saponified alkali, polyethanol adhesives, methyl cellulose adhesives, self-emulsion, and starch adhesives. Since the raw materials of starch adhesive are easily available and the preparation process is simple, that is, the production at room temperature, the manufacturing cost, many paper tube manufacturers prefer to use starch adhesives, and the disadvantages of starch adhesives are that the initial adhesive force is small and the moisture is easy to damp, and the paper tubes are made The wear resistance, pull resistance and compressive resistance are all relatively poor.

4.0-8.0 parts of sodium and 0.5-3.0 parts of borax. In order to reduce the production cost of the enhancer, the calcium carbonate used in the present invention is heavy calcium carbonate.
The preparation process of the present technology is as follows: first mix the calcium carbonate powder and potassium permanganate of the component A according to the above formula, and dilute with water to an aqueous solution with a solid content of 20%-25%; then, according to the above formula, the component B is hydrogenated Sodium and borax are mixed and diluted with water to an aqueous solution with a solid content of 12% to 16%. Finally, the aqueous solution of component A and the aqueous solution of component B are mixed and allowed to stand for 12 hours. Then, the starch adhesive can be added at room temperature to prepare a starch adhesive.
The utility model has the following positive effects: 1. The paper tube produced has a high compressive strength and is tested by a pressure pump. Before the force enhancer, the paper tube with a diameter of 250 cm is subjected to a pressure of 6 to 7 atmospheres per square and joined. After this enhancer is l2-14 atmospheric pressure: 2, is not easy to damp, after testing, before the addition of the enhancer made of paper tube placed 10-20 days damp deformation, after adding the enhancer for 6 months without moisture, No deformation: 3, wear-resistance, before the addition of the reinforcing agent to produce a paper tube trimming, trimming, grinding and raising the hair, after adding the reinforcing agent, the paper tube trimming, trimming, and grinding can not be fluffed.
