Embodiment 1

[0023] A low-odor, high-toughness UV-curable adhesive. In terms of weight percentage, the raw materials are: 36% acrylic modified polyurethane resin, 43% acrylic monomer diluent, 14% toughening monomer, and 3% photoinitiator , 3% silane coupling agent, 0.1% inhibitor, 0.5% defoamer, 0.4% wetting agent.

[0024] The preparation method of above-mentioned a kind of low smell, high tenacity ultraviolet curing adhesive, it comprises the following steps:

[0025] (1) Weigh acrylic modified polyurethane resin and acrylic monomer diluent in the reaction kettle according to the proportion of the formula, and stir for 2-3 hours in the dark at a speed of 150-300 r / min to obtain a uniform dispersion liquid;

[0026] (2) Add silane coupling agent, polymerization inhibitor and other additives in proportion, rotate at 150-300 r / min, and continue to stir for 30 minutes;

[0027] (3) Add equal proportions of photoinitiators in batches, with a rotation speed of 150-300 r / min, and gradually inc...

Embodiment 2

[0032] A low-odor, high-toughness UV-curable adhesive. In terms of weight percentage, the raw materials are: 30% acrylic modified polyurethane resin, 45% acrylic monomer diluent, 20% toughening monomer, and 2% photoinitiator , 3% silane coupling agent.

[0033] The preparation method and steps of the above-mentioned examples are the same as those in Example 1.

Embodiment 3

Abstract

A low-odor and high-toughness ultraviolet curing adhesive comprises the following raw materials in percentage by weight: 25-50% of acrylic modified polyurethane resin, 45-70% of an acrylic monomer diluent, 15-45% of a toughening monomer, 2-3% of a silane coupling agent, 2-3% Of a photoinitiator, 0-0.2% of a polymerization inhibitor and 0.1-0.5% of other auxiliaries; compared with the prior art, the low-odor and high-toughness ultraviolet curing adhesive has the beneficial effects of being small in odor, high in toughness, resistant to ethylene oxide sterilization and damp-heat aging, and qualified in biological evaluation performance, and can be used for bonding among common polymer materials such as PVC, PC, ABS and k-resin used in medical instruments.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a low-odor, high-toughness UV-curable adhesive and a preparation method thereof. Background technique [0002] UV-curable adhesives are a type of environmentally friendly adhesives composed of photosensitive resins, reactive diluents, photoinitiators and other related additives. [0003] Light-curing adhesives are especially suitable for assembly line operations due to their fast curing speed and low energy consumption, and are widely used in the medical device industry. For example, indwelling needle products, infusion pump products, breathing circuits, breathing masks, endotracheal tubes, etc., all involve UV-curable adhesives in the assembly and production of products, which are used for bonding between accessories. [0004] However, the UV-curable adhesives currently used in the field of medical devices generally have problems such as strong odor, skin irritation, ...
