Embodiment 2

[0030] Based on the above examples, the adhesive includes the following components in parts by weight: 100 parts of starch, 300 parts of solvent water, 5 parts of 30% caustic soda, 10 parts of 10% caustic soda, 5 parts of 10% caustic soda Borax solution, 0.7 parts of stabilizing agent, 2.4 parts of low-temperature additive; Described stabilizing agent comprises the component of following percentage by weight: polyvinyl formal 68%, hydroxyethyl cellulose 35%; Described low-temperature additive comprises following weight percentage Components: polyvinyl alcohol 52%, urea-formaldehyde resin 35%, light calcium carbonate 12%, other resin 6%. In this example, the adhesive has very good viscosity stability when the temperature is above 10°C, and it does not precipitate when placed. When the temperature is as low as 2°C-10°C, it is stored for 24 hours and can quickly recover to the initial viscosity and performance of the finished product with only short stirring.

Embodiment 3

[0032] Based on the above examples, the low-temperature paper starch adhesive includes the following components in parts by weight: 135 parts of starch, 450 parts of solvent water, 7 parts of 30% caustic soda, 19 parts of 10% caustic soda solution, 26 parts of borax solutions with a concentration of 10%, 1.2 parts of stabilizers, and 3.3 parts of low-temperature additives; the stabilizers include the following components in percentage by weight: polyvinyl formal 68%, hydroxyethyl cellulose 35%; The low-temperature additive includes the following components in weight percentage: 52% of polyvinyl alcohol, 35% of urea-formaldehyde resin, 12% of light calcium carbonate, and 6% of other resins. In this example, the adhesive has very good viscosity stability when the temperature is above 10°C, and it does not precipitate when placed. When the temperature is as low as 2°C-10°C, it is stored for 24 hours and can quickly recover to the initial viscosity and performance of the finished p...

Abstract

The invention discloses a low-temperature production process for a corrugated paper board. The low-temperature production process for the corrugated paper board comprises the following steps: corrugation pressing, adhesive preparation, adhesion paper coating, and drying and shaping, wherein the adhesive preparation is that an adhesive is prepared, and the adhesive comprises the following components in parts by weight: 100-135 parts of starch, 300-450 parts of solvent water, 5-7 parts of caustic soda solution with a concentration of 30%, 10-19 parts of caustic soda solution with a concentrationof 10%, 5-26 parts of borax solution with a concentration of 10%, 0.7-1.2 parts of stabilizer, and 2.4-3.3 parts of low-temperature additive; and the adhesion paper coating is that corrugated core paper is subjected to the corrugation pressing, then conveyed to an adhesive coating machine by a transfer device, coated with the adhesive, pressed-covered with face paper and lining paper, laminated into the corrugated paper board on the adhesive coating machine, and then subjected to grinding machining, and the adhesive coating temperature is 54-58 DEG C. The paper board produced by the low-temperature production process for the corrugated paper board is extremely high in moisture resistance, breakage resistance and water resistance.

Description

technical field [0001] The invention relates to a production process, in particular to a low-temperature production process of corrugated cardboard. Background technique [0002] Corrugated cardboard first started at the end of the 18th century. In the 19th century, people discovered that corrugated cardboard is not only light in weight, strong in performance, and cheaper than ordinary materials, but also has a simple manufacturing process and a wider range of uses. Not only that, corrugated cardboard is not only a recyclable and environmentally friendly material composed of wood fibers that can be decomposed by natural functions, but also can be reused without affecting its performance. Therefore, it is favored by people. [0003] The performance of the existing adhesive is unstable under low temperature and low pressure conditions; the adhesive is particularly sensitive to temperature, and the temperature affects the viscosity and adhesion of the adhesive. If the tempera...
