Abstract

The invention discloses a high-temperature-resistant epoxy resin composite material which is characterized by being prepared from the following raw materials in parts by weight: 45-55 parts of E-12 epoxy resin, 1-3 parts of talcum powder, 2-4 parts of pomegranate bark, 0.7-1.1 parts of ammonium persulfate, 3-5 parts of anacardol, 3.4-5.7 parts of propylene glycol, 4.3-6.8 parts of 1,4-cyclohexanedimethanol, 5.2-7.9 parts of glycolic acid, 3-4 parts of erucyl amide, 1-3 parts of benzoyl peroxide, 7-12 parts of paraffin emulsion, 8-10 parts of dioctyl sebacate, 7-9 parts of alkylated pentaerythritol tetraacrylate, 0.6-0.9 part of dibutyltin dilaurate, 6-9 parts of triethanolamine and 4-7 parts of aids. According to the composite material disclosed by the invention, the production process is optimized, when the pomegranate bark and other conventional modified epoxy resins are added, the other active ingredients are added to be reacted to generate novel resins, the epoxy resin is modified again, the composition prepared by the invention has excellent high-temperature resistance and ageing resistance, the balance among the process performance, impact toughness and overall performance is maintained, and the prepared product can be used in a harsh high-temperature field environment for a long time and is wide in market prospects.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to a high-temperature-resistant epoxy resin composite material and a manufacturing method thereof. Background technique [0002] Epoxy resins generally refer to organic compounds containing two or more active epoxy groups in the molecule, which can cross-link with various types of curing agents to form insoluble and infusible three-dimensional network structures. polymers. With excellent electrical insulation, mechanical, bonding, chemical corrosion resistance and good physical and chemical properties, it is widely used as laminates, adhesives, coatings, etc., and is more and more popular in the fields of ships, automobiles, aerospace, etc. Pay attention to. [0003] At present, epoxy resin is used as the matrix of composite materials, showing many problems, such as low hardness, poor insulation, softening by heat, easy delamination, difficult mass and heat transfer, and...
