Embodiment 1

[0056] Embodiment one: the preparation of water-soluble double-sided adhesive tape

[0057] 1. Preparation of acrylate polymer: Add 60 parts of viscous monomer isooctyl acrylate, 25 parts of internal polymeric monomer methyl acrylate, 8 parts of crosslinking monomer acrylamide, 60 parts of methanol and 90 parts of ethyl acetate into four Stir and heat the flask to 70°C, add 0.3% of the initiator azobisisobutyronitrile to react at reflux temperature for 6 h, cool down to 35°C, add polyoxyethylene ether surfactant and appropriate amount of methanol and stir evenly, Finally add 0.1% of curing agent aluminum acetylacetonate.

[0058] This tape greatly improves the water solubility speed by adding a large amount of hydrophilic cross-linking monomers and polyoxyethylene ether surfactants. The multi-cross-linking also greatly improves the glue overflow under the premise of ensuring high initial viscosity. Condition.

[0059] 2) Coat the prepared acrylate polymer on one side of the ...

Embodiment 2

[0070] Embodiment two, the preparation of water-soluble double-sided adhesive tape

[0071] 1. Preparation of acrylate polymer: Add 30 parts of butyl acrylate, 35 parts of vinyl acetate, 25 parts of methyl methacrylate, 7 parts of acrylamide, 3 parts of acrylic acid, 60 parts of methanol and 90 parts of ethyl acetate into four Stir and heat the flask to 70°C, add 0.4% initiator azobisisobutyronitrile to react at reflux temperature and keep it warm for 6 h, cool down to 35°C, add polyoxyethylene ether surfactant and appropriate amount of methanol and stir evenly, Finally add 0.2% of curing agent aluminum acetylacetonate.

[0072] 2) Coat the prepared acrylate polymer on one side of the water-soluble paper, then cover the outside of the acrylate polymer with release paper, and then coat the other side of the water-soluble paper with acrylate polymer to complete the water-soluble For the preparation of double-sided tape, the water-soluble double-sided tape is made into a roll fo...

Embodiment 3

[0074] In order to improve the cutting efficiency of roll-shaped double-sided tape during use and save manpower and sticking time, this embodiment discloses a double-sided tape cutting device, which mainly includes three parts: a cutting mechanism 1, a conveying mechanism 2 and a clamping mechanism 3. major institutions such as figure 2 As shown, the conveying mechanism 2 is arranged on the front side of the cutting mechanism 1, and the clamping mechanism 3 is arranged on the left end of the cutting mechanism 1;

[0075] The cutting mechanism 1 includes a top plate 12 and a bottom plate 13 connected by a telescopic column 11, two groups of electromagnetic devices 14 are correspondingly arranged between the top plate 12 and the bottom plate 13, and the two groups of electromagnetic devices 14 are respectively arranged at both ends of the rear side of the cutting mechanism 1 , the electromagnetic device 14 includes a magnetic block 141, an iron core 142 and a conductive coil 14...

Abstract

The invention discloses a water-soluble double-sided adhesive tape and a double-sided adhesive tape cutting apparatus, wherein the water-soluble double-sided adhesive tape has a four-layer structure,and sequentially comprises release paper, an acrylate polymer layer, water-soluble paper and an acrylate polymer layer, and the acrylate polymer layer mainly comprises: a viscous monomer, a cohesive monomer, a cross-linking monomer, methanol, ethyl acetate, an initiator, a surfactant and a curing agent aluminum acetylacetonate. According to the present invention, the double-sided adhesive tape prepared from the high-performance acrylate polymer has high initial adhesion and good water solubility, the connecting point does not easily slide and shift when the double-sided adhesive tape is used in the paper overlapping process in papermaking and printing industries, and the double-sided adhesive tape can be quickly dissolved in water after being used so as not to affect the recycling of products; and the double-sided adhesive tape cutting apparatus can cut to obtain multiple double-sided adhesive tape sections at a time so as to solve the problems of more steps, time consuming and labor consuming of the traditional multi-section cutting.

Description

technical field [0001] The invention relates to the technical field of double-sided adhesive tape preparation, in particular to a water-soluble double-sided adhesive tape and a double-sided adhesive tape cutting device for cutting the water-soluble double-sided adhesive tape. Background technique [0002] With the development of modern high-speed papermaking, paper processing and printing industries, water-soluble adhesive tapes have been more and more widely used in the paper lapping process of papermaking and printing industries. It can be dissolved in water, and after use, it will not affect the product recovery, secondary production and the quality of the original product. [0003] However, the water-soluble pressure-sensitive tapes currently on the market have low initial tack, which can cause the joints to slide and shift. Secondly, the water solubility is poor, and the glue cannot be completely dissolved quickly, which has a serious impact on product recycling. [0...
