Description

A kind of antistatic high-adhesive acrylate adhesive and its preparation technology
Technical field
The present invention relates to field of adhesive technology is and in particular to a kind of antistatic high-adhesive acrylate adhesive and its system Standby technique.
Background technology
Adhesive, also known as binding agent, abbreviation glue (bonding agent, adhesive), is to make object tight with another object The close nonmetallic media material connecting as one.Between two adherend faces, adhesive only accounts for very thin one layer volume, but makes After completing to glued joint construction with adhesive, gained bonded part, in terms of mechanical performance and physical and chemical performance, can meet actual need The requirements wanted.Can effectively by materials from bonding together.
Acrylate adhesive raw material sources are extensive, preparation process is simple, have drying and moulding rapidly, the transparency is good, To multiple material, there is good bond performance, and weatherability, resistance to water, chemical proofing are also good.Particularly to hydrophobic table Facestock material also has excellent cohesiveness, and the resistance to weathering of this rubber-like adhesive can be more excellent, and easy to use, bonding connects Head durability is good.The curing mechanism of acrylate adhesive is：Under light or heat effect, under initiator effect, promote acrylic acid In double bond open, carry out radical chain additive reaction.Can be with oxidative cure：Cause radical chain under oxygen effect Polyreaction.Traditional adhesive, can discharge harmful substance in the curing process, lead to VOC often too high, be human health Potential " killer ".
Traditional adhesive, VOC is often too high, is potential " killer " of human health；This product, uses as much as possible The material of low volatility, protects the health of the mankind and environment effectively from source.Meanwhile, preparation for the purpose of environmental protection at present In adhesive, therefore lose the advantage that these raw materials bring, the relative adhesion strength reduction of the adhesive of preparation increased use Amount, relative viscosity increases and increased and use difficulty.In addition, current adhesive easily accumulates electrostatic after a procedure.
Content of the invention
The invention aims to solving the above problems, provide a kind of antistatic high-adhesive acrylate adhesive and its Preparation technology.
