Embodiment Construction

[0033] An environmentally friendly glue for corrugated cardboard high-speed production lines, which is prepared from the following raw materials in weight percentages:

[0034] Water: 70%, corn starch 26.3%, alkali 1.8%, borax: 0.5%; It is 56°C, the viscosity of the single-facer machine is 16s, and the gelatinization temperature of the single-facer machine is 58°C.

[0035] The preparation method of environment-friendly glue for above-mentioned corrugated cardboard high-speed production line, it is made up of following steps:

[0036] 1. Add the formula amount of water to the glue tank and heat it at 28°C;

[0037] 2. Put the water in the mixing tank, pour half of the lye in the formula into the mixing tank and stir, add the corn starch in the formula after 10 minutes, and stir for 10 minutes; slowly add the other half of the lye and stir, stir After uniformity, add the formula amount of bridging agent and stir for 10 minutes. After completely stirring evenly, add the formul...

Abstract

The invention discloses an environment-friendly glue for a corrugated board high-speed production line. The glue is characterized by being prepared from the following raw materials by weight: 70% of water, 26.3% of corn starch, 1.8% of alkali lye, 0.5% of borax and 1.4% of a bridging agent. For the environment-friendly glue used for the corrugated board high-speed production line, the viscosity of a gluing machine is 18 s, the gelatinization temperature of the gluing machine is 56 DEG C, the viscosity of a single-side machine is 16 s, and the gelatinization temperature of the single-side machine is 58 DEG C. The invention also discloses a preparation method for the environment-friendly glue used for the corrugated board high-speed production line. The environment-friendly glue provided by the invention has the characteristics of low preparation and usage temperature, high adhesive strength, quick-drying performance, environment-friendliness and low usage cost; and the preparation method has the advantages of reasonable technology, easiness, low preparation temperature and capacity of improving adhesiveness of the adhesive glue.

Description

technical field [0001] The invention relates to glue for a corrugated cardboard production line, in particular to an environment-friendly glue for a high-speed corrugated cardboard production line. Background technique [0002] As we all know, the formation of corrugated cardboard is inseparable from starch adhesive, and the main function of starch adhesive is to bond corrugated paper and face paper to form corrugated cardboard. The starch adhesives used by most carton companies today are mainly raw rubber. The disadvantages of this kind of raw rubber are poor stability, complicated manufacture, unstable viscosity, degumming phenomenon from time to time, large loss, and high gelatinization temperature. [0003] The existing problems of adhesives used in traditional heat-setting corrugated board production lines are as follows: [0004] 1. Adhesive is glue. The amount of glue directly affects the amount of water, and the molecular structure of traditional cornstarch determ...
