Example Embodiment

[0034] Example 1

[0035] Table 1 selects the following components by mass percent fraction:

[0036]

[0037] The method for preparing Example 1 is: first weigh each material according to the components given in Table 1; then put the aromatic polyether urethane diacrylate into a light-tight brown glass container (select the light-proof brown glass container In order to achieve shading and prevent monomers from reacting), then sequentially pour isobornyl acrylate, hydroxyethyl acrylate, hydroxyethyl methacrylate, methyl benzoylformate, methacrylic acid and hydroxyphosphate acrylate; After a stirring speed of 60 rpm and a stirring time of 5 minutes, a uniformly stirred and mixed UV-curable adhesive was prepared.

[0038] The UV-curable adhesive prepared in Example 1 was subjected to a viscosity test. The test equipment was a British BohlinrhRH 2000 rotational rheometer, and the viscosity test method was the plate method. figure 2 It is the viscosity test result of the U...

Abstract

The invention discloses a low-viscosity low-contact angle cold tolerance ultraviolet light polymerization adhesive foe bonding glass, which comprises the following components in percentage by weight: 30%-80% of reactive diluents, 10%-45% of resin, 1%-10% of photoinitiator and 5%-15% of additive. According to the invention, low temperature resistant resin, low viscosity but high adhesive ability reactive diluents and additive which can improves the interfacial property are adopted to obtain a low-viscosity low-contact angle cold tolerance ultraviolet light polymerization adhesive for bonding glass by adjusting the flexible chain content, additive content and the resin ratio. The adhesive for bonding glass has the characteristics that the viscosity is less than 1P, the contact angle of the glass surface is less than or equal to 20 degrees, the adhesive can be used in the bonding of precise tiny components, and has a high shear strength at room temperature and a resistance at a very low temperature, thereby having a wide application prospect in the information transmission, microelectronics, superconductivity and other fields.

Description

technical field [0001] The present invention relates to an adhesive, more particularly to an ultraviolet curable adhesive used for bonding glass, having low viscosity, low contact angle and low temperature resistance. Background technique [0002] UV curing technology is a high-efficiency, energy-saving and environmentally friendly high-tech, with adjustable performance, no or low VOC (volatile organic compound) emissions, energy saving, fast curing speed, low curing temperature, high production efficiency, suitable for assembly line production , The coating equipment has the characteristics of small size, small footprint, small investment, and is suitable for coating heat-sensitive substrates. It is mainly used in the fields of coatings, inks, adhesives and other materials. [0003] In high-tech fields such as microelectronics, optics, and precision instruments, it is often necessary to assemble some tiny components. With the miniaturization and high speed of integrated ci...
