preparation example Construction

[0024] Such as figure 1 Shown, a kind of preparation method of the environmental protection daily chemical label that can be washed away from recovery, comprises the following steps:

[0025] A. Apply removable glue on any side of the surface material 1 and any side of the backing paper 2 to form a removable glue layer 3;

[0026] B. Coating a foaming agent or thermal expansion agent on the side of the surface material 1 coated with the removable glue to form a functional layer 4;

[0027] C. Composite the side of the surface material 1 coated with a foaming agent or thermal expansion agent and the side of the base paper 2 coated with the removable glue to obtain an environmentally friendly day that can be washed, detached and recycled. label.

[0028] By coating removable glue on either side of the surface material 1 and the bottom paper 2, and then coating the side of the surface material 1 coated with the removable glue with a foaming agent or a thermal expansion agent, t...

Embodiment 1

[0057] A preparation method of an environmentally friendly daily chemical label that can be washed and separated from recycling, comprising the following steps:

[0058] A. Apply removable glue on any side of the surface material (specifically, white OPS heat shrinkable film with a thickness of 50 μm) and any side of the backing paper (specifically, a PET backing paper with a thickness of 36 μm). The coating amount of glue is 21g / m 2 ;

[0059] Wherein, the preparation method of described removable glue comprises the following steps:

[0060] (1) Dissolve 0.3 parts of sodium persulfate in 10 parts of ethyl acetate, then add 4 parts of isooctyl acrylate, 4 parts of acrylic acid, 13 parts of methyl acrylate and 50 parts of toluene, stir and mix evenly to obtain a mixed solution;

[0061] (2) Add 10 parts of ethyl acetate into the reactor and raise the temperature to 80° C., after the reflux is stable, add the mixed solution prepared in the step (1) dropwise, and keep the react...

Abstract

The invention discloses a preparation method of an environment-friendly daily chemical label capable of being separated and recycled by water washing and a product thereof, the preparation method of the environment-friendly daily chemical label capable of being separated and recycled by water washing comprises the following steps: A, any surface of a surface material and any surface of bottom paper are respectively coated with removable glue; b, the face, coated with the movable glue, of the plane material is coated with a foaming agent or a thermal expansion agent; and c, the face, coated with the foaming agent or the thermal expansion agent, of the face material is compounded with the face, coated with the movable glue, of the bottom paper, and the environment-friendly daily chemical label capable of being washed, separated and recycled is obtained. According to the preparation method of the environment-friendly daily chemical label capable of being separated and recycled through water washing, the preparation method is simple, the prepared label can fall off through water washing, the falling-off speed is high, the separation effect with a bottle body is good, the separation integrity is good, the prepared environment-friendly daily chemical label capable of being separated and recycled through water washing can fall off through water washing, the use convenience is high, and the use effect is good.

Description

technical field [0001] The invention relates to the technical field of labels, in particular to a preparation method and a product of an environmentally friendly daily chemical label that can be washed, detached and recycled. Background technique [0002] When designing the packaging, it is usually necessary to attach the label to the body of the bottle. At present, most of the labels on the bottle are paper labels, PE labels, BOPP labels, pearlescent film labels and PET labels, etc., while most bottles on the market The materials of the body are mainly glass containers, PETG containers and PET bottles. When the label and the bottle are bonded together, it is difficult to separate the label from the bottle. Even if it can be separated, the label is easy to remain on the bottle and the separation is complete. low performance and low separation efficiency. In general bottle recycling, it is necessary to separate the bottle cap, bottle body and label, because their melting poi...
