Abstract
The invention relates to a method for preparing an additive of epoxy resin. The additive of the epoxy resin comprises the following components in parts by weight: 50-70 parts of epoxy resin, 10-15 parts of diethanol amine, 20-40 parts of nylon 6, and 0.5-2 parts of ammonium acetate. The additive of the epoxy resin is prepared by the following steps of weighing the epoxy resin, diethanol amine, nylon 6 and ammonium acetate according to the parts by weight, then adding nylon 6 into ammonium acetate to be dissolved, adding epoxy resin and diethanol amine and mixing uniformly, dripping excessive water till no white precipitate is generated, filtering the white precipitate and stoving so as to obtain white lumps, smashing the lumps into white powder. The additive of the epoxy resin has good effect in enhancing polypropylene, and the modified polypropylene material has good rigidity and strength and can be processed into automobile parts, electronics parts and the like.
Description
Technical field
The present invention relates to a kind of epoxy resin auxiliary agent preparation method, being specifically related to a kind ofly has good reinforced effects to polypropylene, the modified polypropylene material obtaining has good rigidity and intensity, the epoxy resin auxiliary agent that can be used for being processed into auto-parts, electronic apparatus part etc., belongs to chemical material field.
Background technology
Epoxy resin is originally as thermoplastic linear structure, and after being heated, solid resin can soften, melt, and becomes thickness state or liquid state; Reduced viscosity after liquid-state epoxy resin is heated; After only adding solidifying agent to solidify, epoxy resin just can obtain practicality.The epoxy resin compositional system of a complete concept should be become to be grouped into by four aspects: one: resinous principle (epoxy resin and solidifying agent), two: altered contents (softening agent, toughner and weighting agent), three: influence liquidity composition (dilution is neat " and thixotropic agent), four: other compositions.When practical application, not necessarily the composition of four aspects all will possess simultaneously, but solidifying agent in resinous principle is essential really, visible solidifying agent important.So epoxy resin can be obtained widespread use, be exactly because the result of the multiple cooperation of these compositions.Especially solidifying agent, once after epoxy resin determines, solidifying agent plays a decisive role to the performance of the manufacturability of epoxy resin component and cured product (product).A Japanese expert thinks: " development of new solidifying agent is more even more important than development of new epoxy resin, because some resins of delivering on document, although there is learning value, there is no practice significance more.And develop a kind of Novel curing agent, can solve a problem of epoxy resin application ".
Epoxy resin itself is thermoplastic linear structure; can not directly bring application; must in resin, add second component; under the conditions such as certain temperature (or humidity); carry out polyaddition reaction with the epoxy group(ing) of epoxy resin; or catalytic polymerization, after the cured article of generating three-dimensional network structure (build reticulated structure), could use; This compound or resin that serves as second component is called solidifying agent, conventionally can be divided into add-on type and catalyst type solidifying agent.
Epoxy resin is one of three large universal thermosetting resins, has good mechanical property, electrical insulation capability, thermostability, chemical-resistant and adhesive property, is widely used in the fields such as electric, machinofacture, aerospace, ship.Continuous increase along with social development people environmental consciousness, the water-borne modification of epoxy resin that the water of take is solvent or dispersion medium more and more comes into one's own, the epoxy resin of Water-borne modification modification not only has the advantage of solvent epoxy varnish concurrently, and VOC (volatile organic compounds) content is low, application property is good, easy to clean, and safety is used in accumulating, cheap, thereby become one of developing direction of epoxy resin application.
Polypropylene is a kind of widely used resin, has good mechanical property, but its rigidity and intensity are not high, and difficult resistance meets the requirement of engineering materials.In order to improve polyacrylic rigidity and modulus, conventionally add therein mineral filler and glass fibre.Mineral filler and glass fibre belong to inorganic materials, and they and this organic materials of polypropylene are difficult for combining preferably.Epoxy resin is a kind of organic materials, and has excellent cementability, high stiffness and intensity.Chinese patent CN 02155007.7 has reported that epoxy resin is joined to the material of preparing in polypropylene good rigidity and intensity, but the epoxy resin of mucus state is added and has the easily operational inconvenience such as sticky hand, sticky equipment, mucus leakage of mucus while mixing with polypropylene in equipment.
The present invention has adopted epoxy resin, diethanolamine, nylon 6, ammonium acetate to prepare a kind of brand-new epoxy resin auxiliary agent, this epoxy resin auxiliary agent has good reinforced effects to polypropylene, the modified polypropylene material obtaining has good rigidity and intensity, can be used for being processed into auto-parts, electronic apparatus part etc., relevant patent has not yet to see application at home.
Summary of the invention
The object of this invention is to provide a kind of epoxy resin auxiliary agent preparation method, being specifically related to a kind ofly has good reinforced effects to polypropylene, the modified polypropylene material obtaining has good rigidity and intensity, can be used for being processed into the epoxy resin auxiliary agent of auto-parts, electronic apparatus part etc.
