Abstract
The invention relates to a room-temperature-curing toughened epoxy resin adhesive and a preparation method thereof, belonging to the field of high polymer materials. The epoxy resin adhesive is prepared from the following raw materials in parts by weight: 40-60 parts of epoxy resin, 30-50 parts of curing agent, 10-20 parts of epoxy polybutadiene, 10-18 parts of dioctyl terephthalate, 3-5 parts of silane coupling agent and 30-50 parts of calcium carbonate. The prepared epoxy resin adhesive can be cured at room temperature, has excellent toughness, and has wide application range. The toughener is added into the room-temperature-curing epoxy resin to perform toughening modification on the epoxy resin, so that the epoxy resin can be well used for preparing various room-temperature-curing epoxy resin adhesives for different techniques and different application targets, and can be better applied to aramid fiber composite materials.
Description
Technical field
The present invention relates to a kind of epoxyn and preparation method thereof, more particularly, the present invention relates to a kind of self-vulcanizing toughened epoxy resin adhesive and preparation method thereof, belong to technical field of polymer materials.
Background technology
Epoxy resin is a kind of thermosetting resin, because having the characteristics such as excellent cementability, physical strength and electrical insulating property, and is widely used in the aspects such as tackiness agent, high-performance-light weight fibre reinforced composites, coating and matrices of composite material.In addition, epoxyn is because its good performance is widely used in sqtructural adhesive.But the ability that its obvious fragility and poor weathering resistance, resistance to fatigue, thermotolerance, water absorbability and shock resistance make it bear applied external force under heavily stressed is poor, is its unavoidable shortcoming.Therefore, need to carry out modification to epoxy resin.In addition, because epoxy resin viscosity is higher, to the feature such as the wetting property of aramid fiber is poor, epoxy resin to be performed well in to the preparation of aramid fiber reinforced composite, must carry out necessary modification to epoxy resin, make prepared aramid fiber/epoxy resin composite material there is best over-all properties.
It is CN101157835 that State Intellectual Property Office discloses a publication number in 2008.4.9, name is called the patent of invention of " a kind of modified epoxide resin adhesive and application thereof ", the tackiness agent that this patent provides a kind of effectively fixing spring, makes spring be not easy to come off from spring groove.The present invention provides the application of this tackiness agent aspect fixing spring simultaneously.Modified epoxide resin adhesive of the present invention, comprises the component of following mass parts: epoxy resin 100; Poly-sulphur glue 50 ~ 200; White carbon black 5 ~ 15; Coupling agent 1 ~ 5; Amine curing agent 2 ~ 10.Compared with ordinary epoxy resin: the present invention adopts thiorubber to carry out modification to epoxy resin, it is a kind of toughness reinforcing method of reactive liquid polymerization, after thiorubber mixes with epoxy resin, thiol group and epoxy group(ing) in poly-sulphur glue react, identify oneself with in curing epoxy resin structural, give the snappiness that epoxy resin is good.Therefore modified epoxide resin adhesive of the present invention effectively fixing spring, make spring be not easy to come off from spring groove, kept again other effective performances of epoxy resin simultaneously.
Epoxyn in above-mentioned patent has certain snappiness, but over-all properties is not good, cannot be advantageously applied to aramid fiber reinforced composite.
Summary of the invention
