Description
Technical field
The invention belongs to adhesive field, be specifically related to a kind of tackiness agent based on polyether derivative and preparation method thereof.
Background technology
The loudspeaker central glue is mainly used in the bonding of speaker center position (voice coil loudspeaker voice coil, carton and spring plate).Loud speaker is according to its power difference, the vibration intensity difference, the degree of heating is not identical yet, and for example 200W can reach 100 ℃ with the heating of inside trumpet viscose glue position, and 400W or higher super high power loudspeaker heating temp can reach more than 180 ℃, higher to heat impedance, the shock resistance requirement of loudspeaker central glue.
Nowadays on market, existing loudspeaker glue is vinylformic acid AB glue, and not only stink is large for it, complex manufacturing, production environment are poor, and thermotolerance is inadequate.
Vinylformic acid AB glue, the A component is generally by the MMA(methyl methacrylate) and rubber, MA(methyl acrylate), oxygenant adds various auxiliary agents and forms; The B component generally adds various auxiliary agents by MMA and rubber, MA, reductive agent and forms.As bi-component acrylic glue, its all technical still can, but smell is large, thermotolerance is not good, usually below 100 ℃, this some just limited its range of application.Its general making processes comprises step:
1) add MA and triethylamine pre-reaction 1h in being full of the reactor of water coolant.
2) material of main part that drops into the A component reacts 1h at normal temperatures, drops into the product of pre-reaction in early stage, continues reaction 1h.
3) add anti-aging agent, stopper, promotor etc.
4) add mill base, cooling rear barrelling
5) the B component is produced with reference to the A component
Its complex manufacturing, raw materials for production are various, and operational requirement is many, the proportioning complexity, production environment is poor: the agent of vinylformic acid gluing, can volatilize one niff, in a large amount of production processes, cause workshop condition severe; Human body is had to certain harm; Shock resistance, thermotolerance be not ideal enough (softening temperature >=120 ℃) also.
Urethane is the abbreviation of polyurethane(s), has group-NHCOOR.Polyurethane adhesive is a current just important component part in the urethane resin of fast development, has excellent performance.Adhesive for polyurethane itself has unique performances such as good, low temperature resistant, wear-resisting, the ageing-resistant and shock resistance of snappiness, but thermotolerance is still not ideal enough.The three-dimensional arrangement that organosilicon is main chain by siloxane bond forms, and at high temperature further condensation becomes highly cross-linked hard and crisp resin.If carry out modified polyurethane with organosilicon, can improve the thermotolerance of urethane, make it also there is higher bonding strength under 150 ℃, met the technical requirements of loudspeaker central glues.
