Abstract

The invention discloses a normal-temperature curable resin system for replicating an antenna reflecting surface and a preparation method thereof. The normal-temperature curable resin system comprisesthe following components by weight: A: 90-110 parts of phenolic epoxy resin and 30-40 parts of alicyclic epoxy resin; and B: 4-6 parts of triethylene tetramine and 30-40 parts of an alicyclic amine curing agent. The epoxy resin system obtained by the invention can be used for an antenna reflecting surface normal-temperature replication molding process to obtain a high-precision antenna reflectingpanel.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a normal temperature curing resin system, in particular to a normal temperature curing resin system for duplicating antenna reflection surfaces and a preparation method thereof. Background technique [0002] Due to its low density, high specific stiffness, high specific strength, and small thermal expansion coefficient (close to zero by design), resin-based composite materials have become the most ideal materials for preparing high-precision and high-stability antenna reflectors. However, due to the composite material molding process During the curing process, the difference in thermal expansion coefficient between the resin matrix and the carbon fiber and the curing shrinkage of the resin matrix will cause residual stress inside the antenna panel after curing, and warp and deformation of the antenna reflector panel after demoulding. Therefore, a new The pro...
