AI Technical Summary

Problems solved by technology

Although the paper layer and the plastic film can be combined with traditional adhesives, the composite strength is not high, and it is easy to peel off after a long time
Therefore, this kind of adhesive can only be used on resisting products that have not been used for a long time, and cannot be used on high-grade products (such as various certificates) that have been used for a long time and need to be kept for a long time, and the quality is poor

Embodiment 1

[0026] First choose the toluene of 190 parts by weight, the ethyl methacrylate of 13 parts by weight, the ethyl acetate of 130 parts by weight, the butyl acrylate of 25 parts by weight, the ethyl acrylate of 27 parts by weight, the vinyl acetate of 14 parts by weight, 4 Acrylamide in parts by weight, maleic anhydride in 3 parts by weight and initiator in 1 part by weight are ready for use. Wherein, the initiator is benzoyl peroxide.

[0027] Then, 40% by weight of toluene and 10% by weight of ethyl acetate were charged into the reactor, and heated while stirring. When the temperature rose to 80 degrees Celsius, the temperature was maintained for 16 minutes to obtain the base liquid.

[0028] Afterwards, put ethyl methacrylate, butyl acrylate, ethyl acrylate, vinyl acetate, acrylamide and maleic anhydride in a container, stir and mix to form a mixed solution.

[0029] Afterwards, while the base liquid was uniformly stirred, the mixed liquid was dropped into the base liquid at...

Embodiment 2

[0034] First choose the toluene of 200 parts by weight, the ethyl methacrylate of 15 parts by weight, the ethyl acetate of 135 parts by weight, the butyl acrylate of 30 parts by weight, the ethyl acrylate of 31 parts by weight, the vinyl acetate of 15 parts by weight, 5 parts by weight The acrylamide of parts by weight, the maleic anhydride of 4 parts by weight and the initiator of 1.1 parts by weight are ready for use. Wherein, the initiator is benzoyl peroxide.

[0035] Then, 40% by weight of toluene and 10% by weight of ethyl acetate were charged into the reactor, and heated while stirring. When the temperature rose to 85 degrees Celsius, the temperature was maintained for 14 minutes to obtain the base liquid.

[0036] Afterwards, put ethyl methacrylate, butyl acrylate, ethyl acrylate, vinyl acetate, acrylamide and maleic anhydride in a container, stir and mix to form a mixed solution.

[0037] Afterwards, while the base liquid was uniformly stirred, the mixed liquid was ...

Embodiment 3

[0042] First choose the toluene of 210 parts by weight, the ethyl methacrylate of 18 parts by weight, the ethyl acetate of 140 parts by weight, the butyl acrylate of 35 parts by weight, the ethyl acrylate of 33 parts by weight, the vinyl acetate of 16 parts by weight, 6 The acrylamide of parts by weight, the maleic anhydride of 5 parts by weight and the initiator of 1.2 parts by weight are ready for use. Wherein, the initiator is benzoyl peroxide.

[0043] Then, 40% by weight of toluene and 10% by weight of ethyl acetate were charged into the reactor, and heated while stirring. When the temperature rose to 90 degrees Celsius, the temperature was maintained for 13 minutes to obtain the base liquid.

[0044] Afterwards, put ethyl methacrylate, butyl acrylate, ethyl acrylate, vinyl acetate, acrylamide and maleic anhydride in a container, stir and mix to form a mixed solution.

[0045] Afterwards, while the base liquid was uniformly stirred, the mixed liquid was dropped into the...

Abstract

The invention relates to a pressure-sensitive adhesive. The pressure-sensitive adhesive is characterized by being prepared from 190-210 parts of toluene, 13-18 parts of ethyl methacrylate, 130-140 parts of ethyl acetate, 25-35 parts of butyl acrylate, 27-33 parts of ethyl acrylate, 14-16 parts of vinyl acetate, 4-6 parts of acrylamide, 3-5 parts of maleic anhydride and 1-1.2 part of initiator. The pressure-sensitive adhesive is applicable to both low-grade products having short service time and high-grade products (for example, various certificates) having longer service time and needing to be preserved for a long time, and has good quality.

Description

technical field [0001] The invention relates to an adhesive. Specifically, it is an adhesive used to combine paper layers and plastic films, especially for various paper-plastic composite products such as certificates. Background technique [0002] In the printing industry, it is often encountered that a plastic film needs to be laminated on the outside of the paper layer. For example, to make the cover of various certificates, a layer of plastic film needs to be laminated on the outside of the paper cover to improve the quality and service life of the certificate cover. . Currently, the adhesives used to bond paper layers and plastic films together are traditional adhesives. Although the paper layer and the plastic film can be combined with traditional adhesives, the composite strength is not high, and it is easy to peel off after a long time. Therefore, this kind of adhesive can only be used on resisting products that have not been used for a long time, and cannot be us...
