Embodiment 1

[0050] At room temperature, add 100 parts by weight of oxidized starch to a container containing 110 parts by weight of water, stir evenly so that the oxidized starch is completely dissolved in water to obtain a mixed material liquid; add 4 parts by weight of hydrogen peroxide to the mixed material liquid After that, mix evenly, then add 4 parts by weight of borax and mix evenly, add 20 parts by weight of caustic soda and mix evenly, finally add 0.8 parts by weight of tributyl phosphate and mix evenly, you can get the aluminum foil composite adhesive agent.

Embodiment 2

[0052] The difference between this example and Example 1 is that the amounts of each raw material are different, specifically: 105 parts by weight of water, 120 parts by weight of oxidized starch, 5 parts by weight of hydrogen peroxide, 5 parts by weight of borax, 24 parts by weight of caustic soda and phosphoric acid 0.9 parts by weight of tributyl ester.

Embodiment 3

[0054] The difference between this example and Example 1 is mainly that the amount of each raw material is different, specifically: 100 parts by weight of water, 125 parts by weight of oxidized starch, 6 parts by weight of hydrogen peroxide, 6 parts by weight of borax, 25 parts by weight of caustic soda and phosphoric acid 1 part by weight of tributyl ester.

Abstract

The invention discloses an adhesive for combining aluminum-foil papers and a preparation method thereof, and belongs to the technical field of adhesives. The adhesive consists of the following components: 100-140 parts by weight of oxidized starch, 4-6 parts by weight of borax, 20-30 parts by weight of sodium hydroxide, 4-8 parts by weight of hydrogen peroxide, 0.8-1.2 parts by weight of tributyl phosphate, and 90-110 parts by weight of water. Due to the fact that the adhesive employs the oxidized starch as the main raw material, the cost on raw materials of the adhesive is reduced, and the adhesive is environment-friendly and non-toxic; due to the fact that the hydrogen peroxide, the borax, the sodium hydroxide and the tributyl phosphate are mixed with certain amount of water under the normal temperature according to specific procedures, not only the technology is simple, but also the prepared adhesive can be stored for 12 months without influencing the character of service; therefore, the adhesive is good in stability; moreover, the adhesive contains 13-20% of solid, therefore, the adhesive is good in fluidity and is able to meet the requirements of different combining speeds.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an adhesive for aluminum foil paper compounding and a preparation method thereof. Background technique [0002] With the development of society and economy, the packaging of commodities is also constantly updated. Packaging materials based on paper and plastic films have been gradually replaced by exquisite and beautiful aluminum foil paper. The use of aluminum foil paper is increasing. Production brings new business opportunities. [0003] Aluminum foil paper is made of 10-20 micron thick aluminum foil and 20-70 micron thick paper bonded by glue. The aluminum foil and paper used are very thin, and the amount of glue used is relatively small, which affects the stability and fluidity of the glue. put forward higher requirements. In order to achieve the bonding and compounding of aluminum foil and paper, Chinese invention patent application 201210555478.1 discloses ...
