Problems solved by technology

[0002] Adhesives are also called glue. Adhesives have become one of the most important auxiliary materials in life. They are widely used in packaging operations. Adhesives are sticky substances that connect two separated materials by virtue of their viscous properties. Together, adhesives are divided into natural adhesives and synthetic adhesives, and most natural adhesives are not very viscous and need to be reprocessed to achieve the desired viscosity, but natural adhesives The quantity is relatively small, and synthetic adhesives are needed to fill the vacancy of natural adhesives, and the technology of synthetic adhesives is immature, and adhesives cannot be processed efficiently

Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Attached below figure 1 In detail, a method for preparing an adhesive comprises the following steps:

[0044] S1. Place the skin of the animal in cold water and soak for one day, use a processing device to squeeze and beat the soaked animal skin, and then place the treated skin in lime slurry for soaking;

[0045] S2, adding phenol, water and ricinoleic acid into the lime slurry soaked with peel;

[0046] S3, adding urea-formaldehyde resin or trimethylphenol to S2 to improve the water resistance of the adhesive, adding glycerin or ethylene glycol to S2 to increase the flexibility of the adhesive;

[0047] S4. Stir in an environment of 60° C., let it dissolve evenly, and then complete the preparation of the adhesive.

[0048] Attached below figure 2 , 3 , 4, 7, 8 and 9 describe in detail that the processing device includes a storage chamber 101, a...

Abstract

The invention relates to the technical field of adhesives, in particular to a preparation method of an adhesive. The method comprises the following steps: S1, soaking animal skins in cold water for one day, extruding and beating the soaked animal skins by using a treatment device, and soaking the treated skins in lime slurry; S2, adding phenol, water and ricinoleic acid into the lime slurry soaked with the peel; S3, adding urea resin or trimethylphenol into the S2 to improve the water resistance of the adhesive, and adding glycerin or ethylene glycol into the S2 to improve the flexibility of the adhesive; and S4, performing stirring in the environment of 60 DEG C, and performing even dissolving to complete preparation of the adhesive. A treatment device comprises a storage cavity, a feeding port, a flat laying plate and a flapping component, the feeding port is formed in the storage cavity, the flat laying plate is fixedly connected into the storage cavity, the flapping component capable of extruding the animal skin is slidably connected to the storage cavity, and the two ends of a flapping stick are fixedly connected with meshing wheels.
