Abstract
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.Epoxyn of the present invention comprises the following raw material according to weight parts: epoxy resin 40-60 part, solidifying agent 30-50 part, epoxidized polybutadiene 10-20 part, dioctyl terephthalate 10-18 part, silane coupling agent 3-5 part, calcium carbonate 30-50 part.Epoxyn prepared by the present invention, can self-vulcanizing, has again preferably toughness, has and apply comparatively widely.This patent carries out toughening modifying by the technological approaches adding toughner in room temperature curing epoxy to epoxy resin, so that the preparation of the room temperature curing epoxy adhesive that various preparation technology is different, application purpose is different can be applied to preferably, aramid fiber reinforced composite can be advantageously applied to.
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 aspect such as tackiness agent, high-performance-light weight fibre reinforced composites, coating and matrices of composite material.In addition, epoxyn is widely used in sqtructural adhesive due to its good performance.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 features such as the wetting property differences of aramid fiber, epoxy resin to be performed well in the preparation of aramid fiber reinforced composite, necessary modification must be carried out to epoxy resin, make prepared aramid fiber/epoxy resin composite material have best over-all properties.
It is CN101157835 that State Intellectual Property Office discloses a publication number in 2008.4.9, name be called the patent of invention of " a kind of modified epoxide resin adhesive and application thereof ", this patent provide a kind of can effectively fixing spring, make spring be not easy the tackiness agent come off from spring groove.The present invention provides the application of this tackiness agent in fixing spring simultaneously.Modified epoxide resin adhesive of the present invention, comprises the component of following mass parts: epoxy resin 100; TR sealant 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 in TR sealant and epoxy group(ing) react, identify oneself with in the epoxy resin structural of solidification, give the snappiness that epoxy resin is good.Therefore modified epoxide resin adhesive of the present invention can effectively fixing spring, make spring be not easy to come off from spring groove, maintain 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
The present invention is intended to solve the problems of the technologies described above, and provides a kind of self-vulcanizing toughened epoxy resin adhesive, improves its over-all properties, can be advantageously applied to aramid fiber reinforced composite.
