Abstract
A montmorillonite-modified epoxy adhesive comprises, by mass, 100-120 parts of epoxy resin, 10-20 parts of nano-montmorillonite, 1-5 parts of KH-550 coupling agents, 10-15 parts of butyl glycidyl ether (BGE), 10-15 parts of dibutyl phthalate, 20-30 parts of styrene and 5-10 parts of aluminum hydroxide. The adhesive has the advantages that the shear strength is improved to 35MPa, the compression resistant strength is improved to 4.0Pa*S, the working life is reduced to 30 minutes, requirements for most construction are satisfied, and the adhesive is particularly suitable for adhesion of aluminum structures.
Description
Technical field
The invention belongs to the epoxy adhesive technical field, relate in particular to a kind of improved imvite modified epoxy adhesive.
Background technology
Nano imvite is that smectite clay (comprising that calcium base, sodium base, Sodium/Calcium base, magnesium base cover clay) forms through the dispersion of delaminating, the remodeling of purifying, super-fine classified, special organic composite, and average wafer thickness is less than 25nm, and smectite content is greater than 95%.Has good dispersing property, can widespread use macromolecular material industry as the additive of nanometer polymer macromolecular material, improve shock resistance, antifatigue, dimensional stability and gas barrier property etc., thereby play the effect that strengthens polymkeric substance comprehensive physical performance, improve simultaneously the materiel machining performance.Application in polymkeric substance can be added when polymkeric substance, also can blend add (usually adopting the screw rod blend) when melting.Polynite main component montmorillonite is octahedra by two-layer Si-O tetrahedron and one deck Al-O, the layered silicate crystal of composition, and it mainly is sodium ion that layer contains positively charged ion, magnesium ion, calcium ion, next has potassium ion, lithium ion etc.
Summary of the invention
The technical problem that solves:The invention provides a kind of imvite modified epoxy adhesive, shearing resistance and compressive strength all improve a lot, and shorten working life, satisfy great majority construction needs, are particularly useful for the bonding of constructed of aluminium.
Technical scheme:Imvite modified epoxy adhesive, comprise following composition in mass parts: 100～120 parts of Resins, epoxy, 10～20 parts of nano imvites, 1～5 part of KH-550 coupling agent, 10～15 parts of butylglycidyl ethers, 10～15 parts of dibutyl phthalates, 20～30 parts of vinylbenzene, 5～10 parts in aluminium hydroxide.
Preferred version 1: 100 parts of Resins, epoxy, 10 parts of nano imvites, 5 parts of KH-550 coupling agents, 10 parts of butylglycidyl ethers, 10 parts of dibutyl phthalates, 30 parts of vinylbenzene, 5 parts in aluminium hydroxide.
Preferred version 2: 110 parts of Resins, epoxy, 15 parts of nano imvites, 3 parts of KH-550 coupling agents, 12 parts of butylglycidyl ethers, 12 parts of dibutyl phthalates, 25 parts of vinylbenzene, 8 parts in aluminium hydroxide.
Beneficial effect:
Imvite modified epoxy adhesive provided by the invention, shearing resistance is increased to 35MPa, and the compression strength enhancing all improves a lot to 4.0PaS, and be 30 minutes working life, shortens dramatically, and satisfies great majority construction needs, is particularly useful for the bonding of constructed of aluminium.
