preparation example Construction

[0037] The embodiment of the present application also provides the preparation method of the above-mentioned packaging glue, refer to figure 1 , the method includes the following steps:

[0038] Step S01, weighing PVA and water and adding it into a kettle with stirring, heating and cooling devices, the quality of the PVA accounts for 5%-15% of the total mass of the PVA and water; stage heating and stirring until polyethylene The alcohol is completely dissolved and cooled to 25°C;

[0039] PVA is polyvinyl alcohol, organic compound, white flaky, flocculent or powdery solid, odorless. Soluble in water, insoluble in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc. Slightly soluble in dimethyl sulfoxide. Polyvinyl alcohol is an important chemical raw material for the manufacture of polyvinyl acetal, gasoline-resistant pipes and vinylon synthetic fibers, fabric treatment agents, emu...

Embodiment 1

[0048] Step S110, weighing PVA and water and adding it into a kettle with stirring, heating and cooling devices, the quality of the PVA accounts for 10% of the total mass of the PVA and water; stage heating and stirring until the polyvinyl alcohol is completely dissolved , cooled to 25°C;

[0049] Step S120, weighing 9 parts of the PVA aqueous solution obtained in step S110, and adding it to the glue adjuster; weighing 30 parts of EVA rubber and 0.1 part of borax, and adding them to the glue adjuster; stirring for 50 minutes to obtain a uniform product without particles;

[0050] Step S130, weighing 60 parts of EVA emulsion, adding to the glue adjuster; stirring for 60 minutes to obtain 1# packaging glue.

Embodiment 2

[0052] Step S210, weighing PVA and water and adding it into a kettle with stirring, heating and cooling devices, the quality of the PVA accounts for 10% of the total mass of the PVA and water; stage heating and stirring until the polyvinyl alcohol is completely dissolved , cooled to 25°C;

[0053] Step S220, weighing 8 parts of the PVA aqueous solution obtained in step S210, and adding them to the glue adjuster; weighing 30 parts of EVA rubber and 0.2 parts of borax, and adding them to the glue adjuster; stirring for 60 minutes to obtain a uniform product without particles;

[0054] Step S230, weighing 65 parts of EVA emulsion, adding to the glue adjuster; stirring for 60 minutes to obtain 2# packing glue.

Abstract

The invention provides packaging glue and a preparation method thereof. The packaging glue is prepared from 55 to 65 parts of EVA emulsion, 25 to 35 parts of EVA resin, 8 to 10 parts of PVA water solutions and 0.05 to 0.2 part of borax. Compared with the prior art, the packaging glue has the technical scheme that the EVA emulsion and the EVA resin are matched according to a mass ratio, so that thepackaging glue has high bonding capability; the uniform gluing can also be ensured; in addition, through the addition of borax, the glue preparation is facilitated; the problem of glue throwing during the glue coating is solved. The packaging glue obtained by the preparation method provided by the invention can at least solve the technical problems of the existing bonding agent of high-temperature creeping, glue throwing during the gluing and poor bonding capability.

Description

technical field [0001] The present application relates to the technical field of adhesives, in particular to a packaging adhesive and a preparation method thereof. Background technique [0002] Adhesive bonding (gluing, bonding, cementing, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives, which has the characteristics of continuous stress distribution, light weight, or sealing, and low temperature in most processes. . Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is developing the fastest in modern times and has a wide range of application industries. There are many classification methods of adhesives, which can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type, etc. according to the application method; according to the application object, it can be d...
