Abstract
The invention discloses ultraviolet curing anaerobic adhesive (UV anaerobic adhesive for short). The UV anaerobic adhesive is mainly prepared from the following components in percentage by mass: 50 to 60 percent of acrylic resin, 35 to 40 percent of diluting monomer, 4 to 5 percent of photoinitiator, 2 to 3 percent of peroxide initiator, 0.5 to 1 percent of accelerator, 0.5 to 1 percent of booster action type accelerator and 0.05 to 1 percent of stabilizer. The UV anaerobic adhesive is high in efficiency and stable; in addition, the problems of pollution, waste and the like caused by adhesive overflow and no curing of traditional anaerobic adhesive are solved; meanwhile, the UV anaerobic adhesive can be cemented with opaque metal materials, so the UV anaerobic adhesive is wider in application range, and can be applied to the aspects such as part fixing, structural bonding, plane sealing and screw locking.
Description
Technical field
The present invention relates to a kind of ultraviolet light polymerization (UV) anaerobic adhesive and preparation method thereof.
Background technology
Anaerobic adhesive due to unique anaerobic curing characteristic, so as to have in the assembling manufacturing industry such as automobile, machinery
It is widely applied.Recently as the fast development of assembling manufacturing industry, anaerobic adhesive performance is put forward higher requirement, promoted
The progress of anaerobic adhesive technology.However, the glue overflowed during assembling is difficult to solidify, component contamination can be caused；And its toughness is not high,
Hardening time is long.At present UV adhesive quickly grows at home, in furniture artware, electrical equipment, digital display display screen, electronics, traffic
With building etc. field obtain a wide range of applications.But there is also such as shade bonding and do not solidify drawback so as to which application is restricted.
In order to solve the above problems, foreign countries develop the UV anaerobic adhesives of double consolidated structures, combine UV adhesive and anaerobism
The characteristics of adhesive, with performances such as fast setting, higher, the dash area realization solidifications of structural bond intensity.But double solidification knots
The UV anaerobic adhesive stability of structure is poor, easily condenses under room temperature.Therefore need that to develop a kind of curing efficiency high and good stability badly
UV anaerobic adhesives.
The content of the invention
It is an object of the invention to provide a kind of UV anaerobic adhesives, solve the problems, such as curing efficiency height and good stability.Can be more
The universal bonding suitable for various materials：As magnetic rubber, magnetic plastics, fibre reinforced plastics, fiberglass reinforced plastics,
Piezoelectric ceramics, sintered material, optical fiberss, special alloy etc..
The present invention solves its technical problem, and the technical scheme for being adopted is,
A kind of UV anaerobic adhesives, component and weight/mass percentage composition are：
Preparation method：Acrylic resin, diluting monomer and light trigger are added in a kettle.；High-speed stirred, rises
Temperature, to being completely dissolved, is cooled to room temperature to 90-100 DEG C.It is subsequently adding peroxide initiator, accelerator, kicker 0.5-
1%th, stabilizer stirring, is uniformly dispersed to product.
The present invention have developed it is a kind of both can solidify under ultraviolet irradiation, while and can realize the adhesive of anaerobic curing,
The drawbacks of solidifying under different condition is solved, and the bin stability and curing efficiency of product are good.Due to double initiator systems
It is unstable, therefore adopt the benzoquinone with antioxidation that glue gel is prevented for stabilizer.Additionally, using ITX or TPO and 907
Composite photoinitiator Deng mass ratio improves its curing efficiency.
Specific embodiment
Prepared using following methods in following embodiments：Acrylic resin, diluting monomer are added in a kettle.
And light trigger；High-speed stirred, is warming up to 90-100 DEG C, to being completely dissolved, is cooled to room temperature.It is subsequently adding peroxide initiation
Agent, accelerator, kicker 0.5-1%, stabilizer stirring, are uniformly dispersed to product, obtain final product the UV anaerobic adhesives of the present invention.
Carry out shear strength, hardening time, storage stability test, (1) shear strength to UV anaerobic adhesives respectively：Press
