Abstract

The invention discloses an epoxy resin composite material for powder coating. The epoxy resin composite material is characterized by comprising the following raw materials in parts by weight: 45-55 parts of dicyclopentadiene phenol epoxy resins, 1.2-3.1 parts of zinc naphthenate, 1-3 parts of low-calcium coal ash, 2-3 parts of tungsten disulfide, 6-8 parts of white factice, 4-7 parts of triethylene tetramine, 20-30 parts of phenyl glycidyl ether, 8-12 parts of phosphoric acid tricresol, 10-13 parts of dicyclopentadiene, 11-14 parts of isobutanol, 2.1-3.2 parts of trimethylolpropane, 9-11 parts of diphenylmethane diisocyanate, 8-13 parts of propylene glycol monomethyl ether acetic ester and 4-7 parts of auxiliaries. A preparation process of the epoxy resin composite material is easy and convenient to operate, and the problem of unique performance of the existing traditional epoxy resin is effectively solved; the epoxy resin can be used for preparing a powder coating with low lustrousness, and is high in application property, high in leveling property of the coating, high in curing speed, high in extinction performance of a paint film and high in yellow degeneration resistance.

Description

technical field [0001] The invention relates to the field of polymer composite materials, in particular to an epoxy resin composite material for powder coatings 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 stron...
