Abstract
The present invention relates to a novel epoxy resin toughened by hydroxy-terminated copolymer of butadiene-acrylenitrile (HTBN). In 100 portions of bisphenol-A epoxy resin, 5 to 60 portions of the HTBN, 5 to 100 portions of an acid anhydride solidifying agent and 0 to 6 portions of a trialkylamine catalyst are added, and the mixture is solidified for 10 to 100 hours at 50 to 160 DEG C. The epoxy resin has high bonding performance, high tensile strength and considerably improved toughness.
Description
The invention belongs to epoxy resin modification.
For adhesiveproperties and the toughness that improves Resins, epoxy, the normal fluid rubber that adds, at present, the both at home and abroad employing held carboxylated butadiene-acrylonitrile copolymer (being called for short the butyronitrile carboxylic) more, but butyronitrile carboxylic price height, for this reason, we once make the end isocyanato to the butyronitrile hydroxyl and give polymers, mix with Resins, epoxy, add aromatic amine again and solidify, obtain modified epoxy (the open CN85101895A of Chinese patent).The people was also once arranged in cycloaliphatic epoxy resin, directly added butyronitrile hydroxyl and aromatic amine, be made into the molten use of methylethylketone liquid (U.S3,926,904).Other has a report, is the butyronitrile hydroxyl is given elder generation and acid anhydrides (Succinic anhydried) reaction, makes the butyronitrile hydroxyl and comes modified epoxy (Adv.Chem.Ser, 1985,202,27).
The objective of the invention is to directly improve the toughness and the adhesiveproperties of Resins, epoxy with less expensive butyronitrile hydroxyl.
Main points of the present invention are that dicarboxylic anhydride and Resins, epoxy and butyronitrile hydroxyl direct reaction are solidified.Add tertiary amine catalyst and can improve curing speed, the epoxy resin cured product that obtains has excellent performance.
The invention is characterized in that the butyronitrile hydroxyl needn't be made gives polymers, and can directly be added in the Resins, epoxy, utilize acid anhydrides can and epoxy reaction, again can with the characteristics of hydroxyl reaction, easily flexible butyronitrile hydroxyl rubber segments is incorporated in the stiffening ring epoxy resins reticulated structure and goes, thereby reach toughening effect.
The used Resins, epoxy of the present invention is bisphenol-A type Resins, epoxy.Used butyronitrile hydroxyl molecular weight is 2000-5000, and acrylonitrile content 10～30%, consumption are 5～60% of Resins, epoxy.The used acid anhydrides of the present invention is a MALEIC ANHYDRIDE, Succinic anhydried, and Tetra Hydro Phthalic Anhydride, hexahydrophthalic anhydride, its consumption are 20～100 parts of Resins, epoxy.Used catalyzer is various tertiary amines, as trolamine, and benzyldimethylamine, 246-three (N dimethylamine ylmethyl) phenol (DMP-30), its consumption are 0～6.0% of Resins, epoxy.50～160 ℃ of solidification values, 10～100 hours set times.Embodiment, 100 gram E-44 Resins, epoxy, adding 20 gram molecular weights is 3000, acrylonitrile content is 15% butyronitrile hydroxyl, 80 gram hexahydrophthalic anhydrides and 0.3 gram DMP-30, bonding various test pieces or casting behind the thorough mixing.Solidified 24 hours at 110 ℃.Bonding carbon copper shearing resistance is 300kg/cm
2, shock strength is 9.0kgcm/cm
2Cast sample tensile strength 610kg/cm
2, elongation 10%, 115 ℃ of second-order transition temperatures.
Solidifying agent, catalyst levels is identical with top embodiment, and does not add the butyronitrile hydroxyl, its cured article shearing resistance 240kg/cm
2, shock strength 3.5kg cm/cm
2, tensile strength 310kg/cm
2, elongation 5%, 124 ℃ of second-order transition temperatures illustrate the Resins, epoxy that adds 20 parts of butyronitrile hydroxyls, and mechanical property is improved largely, and especially toughness is improved.
Claims (4)
1, a kind of new propyl cyanide hydroxy toughened epoxy resin is characterized in that in 100 parts of bisphenol-A type Resins, epoxy, adds the butyronitrile hydroxyl of 5-60 part, 5-100 part anhydride curing agent, and the tertiary amine catalyst of 0-6 part, 50-160 ℃ solidified 10-100 hour.
2, by the described propyl cyanide hydroxy toughened epoxy resin of claim 1, used butyronitrile hydroxyl molecular weight is 2000-5000, acrylonitrile content 10-30%.
3, by the described propyl cyanide hydroxy toughened epoxy resin of claim 1, used solidifying agent is an acid anhydrides, and it can be a MALEIC ANHYDRIDE, Succinic anhydried, Tetra Hydro Phthalic Anhydride, hexahydrophthalic anhydride.
4, by the described propyl cyanide hydroxy toughened epoxy resin of claim 1, its used catalyzer tertiary amine is a trolamine, benzyldimethylamine, 2,4,6-three (N dimethylamine ylmethyl) phenol.
