Abstract

The invention belongs to the field of epoxy resin composite material, and discloses an epoxy resin rubber clothes composition, an epoxy resin composite board, and a preparation method thereof. The composition comprises, by weight, 100 parts of a base epoxy resin, 20 to 30 parts of a curing agent, 0.3 to 2.2 parts of an antifoaming agent, 0.3 to 1.1 parts of a leveling agent, 0.6 to 2.2 parts of awetting dispersing agent, 60 to 110 parts of a filler, 1.8 to 2.2 parts of a thixotropic agent, 0.3 to 1.4 parts of a thixotropic enhancer, and 0 to 3 parts of an optional pigment; the base epoxy resin is a liquid bisphenol A epoxy resin with an epoxy equivalent of 184 to 194 g/eq, and viscosity of 10,000 to 15,000cps at 25 DEG C, the curing agent including a curing agent A and a curing agent B, the curing agent A is a fatty amine with an active hydrogen equivalent of 50 to 60 g/eq; the curing agent B is an alicyclic amine with an active hydrogen equivalent of 40 to 95 g/eq; and the weight ratio of the curing agent A to the curing agent B is 1: (1-4). Excellent adhesion performance with glass fiber reinforced epoxy resin composite materials is provided, and the composite board is providedwith better surface processing performance.

Description

technical field [0001] The invention relates to the field of epoxy resin composite materials, in particular to an epoxy resin gel coat composition, an epoxy resin composite board formed by combining the epoxy resin gel coat composition with glass fiber reinforced epoxy resin composite materials, and The preparation method of the composite board. Background technique [0002] Glass fiber reinforced epoxy resin is a good composite material, but the surface hardness is high and it is difficult to process the surface of the product. [0003] CN104149361A discloses a manufacturing method of a carbon fiber composite material propeller by overmolding. In this method, the carbon fiber is coated on the metal propeller hub, and then the composite molding of the propeller is further carried out. During the molding process, the gel coat resin is sprayed on the mold. Gel coat resin used to insulate the mold from the composite material, composition not disclosed. [0004] CN103895290A ...
