Description
Technical field
The present invention relates to a kind of environment-friendly type normal temperature solidifying bi-component polyolefin adhesive, belongs to adhesive technical field.
Background technology
In recent years, the fast development of domestic polyolefin articles, particularly large-scale ornament materials, the bonding of this kind of material need
The adhesive of higher-strength.However, due to polyolefin articles be the material of the low surface polarity of a class (adhesive force), for example poly- second
Alkene, polypropylene or Te Folong etc..For the difficulty of these material bondings is it is well known that traditional method is usually used surface
Treatment technology, such as flame treatment, corona discharge etc. so significantly limit technology and scene applied changing its surface polarity
Work.And existing bonding is carried out using two component adhesive typically.But traditional two component adhesive be generally there are height can
Combustion property and toxicity, and the problem of flexible difference, will be phased out on the premise of environmental requirement increasingly improves.Such as Chinese patent
Application (Authorization Notice No.：CN103911079B) a kind of clear acrylic esters adhesive of normal temp solidified high stvength is disclosed,
The adhesive includes A and B component, and the component A is the methyl methacrylate monomer dissolving certain molecular weight of certain activity
Plexiglass, and add a certain proportion of accelerator and other auxiliary agents composition, the B component is by O-phthalic
Dibutyl phthalate and t-butylperbenzoate class composition.Although, the adhesive itself has certain adhesion strength performance, by
Tri- n -butyltin methacrylate monomer material in its main component, and methyl methacrylate flash-point is low, is a kind of high flammable
Material, it is easy to burn, is unfavorable for environmental protection and the requirement of security performance；Meanwhile, which is reduced using oxidation-reduction system
Activation energy, easily makes adhesive jaundice and affects adhesion strength performance.
