Description
Technical field
The present invention relates to a kind of UV glue, particularly mistake proofing UV electronics sizing agent is indicated in a kind of variable color, the invention still further relates to the preparation method of this sizing agent.
Background technology
UV glue claims again light-sensitive emulsion, ultraviolet cured adhesive, and UV glue refers to a class tackiness agent that must could solidify by ultraviolet light irradiation, and it can be used as caking agent and uses, and the sizing material that also can be used as paint, coating, ink etc. is used.UV is the abbreviation of English Ultraviolet Rays, i.e. ultraviolet light.Ultraviolet ray (UV) is that naked eyes are invisible, is one section of electromagnetic radiation beyond visible ray, and wavelength is in the scope of 10 ~ 400nm.Without shadow adhesive curing principle, be to produce living radical or positively charged ion after light trigger (or photosensitizers) in UV solidify material absorbs UV-light under ultraviolet irradiation, trigger monomer polymerization, crosslinked and connect a chemical reaction is converted into tackiness agent solid-state within the several seconds by liquid state.It is mainly used in the self-adhesion of the materials such as plastics and plastics, plastics and glass, plastics and metal, artwork industry plastics and sticky mutually, furniture industry, for example tea table glass and steelframe are bonding, fishbowl is bonding, comprises the bonding of the thermoplasticss such as PMMA acrylic (synthetic glass), PC, ABS, PVC, PS.Due to its quick-setting performance, investigate rapidly issuable problem in glue curing and will become extremely meaningful.
Delo company has phototropic resin at present, but expensive, and needs to be in actual applications subject to the performance limitations of this resin.Except the photochromic product of Delo series can intuitively be observed, error-proof UV glue does not have detailed applications at present.After general UV glue curing, must can judge whether UV glue solidifies through a series of functional detections (as bonding force test, hardness test, UV-DSC detect).After existing UV glue curing, can not understand immediately its state of cure, be cured degree analyzing and face again time lag, characterization processes complexity etc. defect.If the glue before solidifying does not detect, cannot judge that whether its performance is still stable.The stable performance that the off-color product of Delo can judge glue in advance whether, can not extensively be applied but be limited to its resin self character (bonding force is strong and weak, tensile modulus for viscosity, hardness).
Summary of the invention
Problem to be solved by this invention is the product line mistake proofing problem while assembling electronic product for use UV glue, provides a kind of Process of Applying Glue of observing immediately after applying glue finishes whether to have extremely, give the variable color indication mistake proofing UV electronics sizing agent that produces line very first time mistake proofing performance.
Another technical problem to be solved by this invention is to provide the preparation method of above-mentioned sizing agent.
Problem to be solved by this invention is to realize by following technical scheme.The present invention is a kind of variable color indication mistake proofing UV electronics sizing agent, is characterized in: raw material and the weight proportion thereof of making sizing agent comprise:
