example

[0182] Below by example, this patent is described in more detail. The composite container of the example is composed of a glass container and a metal base. The scope of application of this patent will certainly not be limited to examples, and this point should not need further explanation.

example 1

[0184] (1) Manufacture of adhesive

[0185] The temperature of the melting bowl should be kept at 180°C. The matrix resin is SIS block polymer, and the anti-acidification agent is a phenolic anti-acidification agent. The ratio of matrix resin: anti-acidification agent = 100 weight units: 0.2 weight units , Put the two into a melting bowl, use a mixer, and melt while stirring. The stirring and melting time is 3 hours, so that the two are mixed evenly and melted evenly.

[0186] Next, add 3 30 weight units of C5 hydrogenated petroleum resin; water-absorbing macromolecular structure particles adopt isobutylene structure anhydrous maleic acid copolymer, (average particle diameter: 15um, water absorption rate: 200 times) added 35 weight units; interface activity What the agent adopts is polyglycol-glycerol stearate ether, (HLB: 15.7) adds 7 weight units; What the plasticizer adopts is liquid paraffin (fire point: 256 ℃, density: 0.865g / cm 3 ) into 5 weight units; continue to stir...

Abstract

The invention relates to a composite container, bond used in the container and the decomposition method thereof. Due to bonds used, a traditional composite container is decomposed inconveniently. Thecomposite container of the invention comprises a plurality of parts. Each part is adhered by a bond. After absorbing water, the binding power of the bond used will reduce. The composition of the bondis, relative to 100 parts by weight of the matrix resin, the content of bibulous particles with high polymer is 1 part to 200 part by weight. With the structure of bibulous high polymer, the bond is easy to decompose, immerging the composite container in 10degree Cí½100degree C water for 30min to 24 hours, or spraying the composite container by 10degree Cí½100degree C water for 30min to 24 hours, or placing the opposite container in the environment with the temperature 40í½100degree C, and the relative humidity 80í½100úÑRH, for 1 to 24 hours.

Description

technical field [0001] The invention relates to a composite container, an adhesive used therein and a decomposition method of the composite container. Background technique [0002] In recent years, international recycling laws have been promulgated. For composite containers that rely on adhesives to bond together, each component is required to be disassembled and recycled. Labels, plastic seals, and decorative plastic sheets pasted on containers are also required to be easily peeled off during recycling. [0003] But, the used adhesive of traditional composite container only requires strong adhesion, and purpose is only that each part of composite container is firmly bonded together. With traditional composite containers, it is difficult to disassemble the various parts during recycling, and it is also inconvenient to peel off the labels pasted on the container. [0004] Japanese Patent Laid-Open No. 11-217548 discloses a peelable adhesive strip. The adhesive strip consis...
