High-strength and heat-insulation novolac epoxy resin composition board

Abstract

The invention discloses a high-strength and heat-insulation novolac epoxy resin composition board which solves the problems that an existing heat-insulation cushion arranged in a support seat of a heat conveying channel and matched with a pipeline steel baffle is low in pressure resistance and pull resistance strength and a heat bridge phenomenon is prone to form. The high-strength and heat-insulation novolac epoxy resin composition board comprises a high-strength and heat-insulation novolac epoxy resin board and a steel board. A 2-thickness SiO2-Al3O3 ceramic coating (2) is sprayed on the surface of the steel board (1), and the high-strength and heat-insulation novolac epoxy resin board (3) is stuck with the steel board with the SiO2-Al3O3 ceramic coating through adherence glue capable of resisting the high temperature of 500 DEG C. A composition board structure is applied to the fixed baffle of the heat conveying channel and taken as a heat-insulation component in the support seat of the pipeline, the heat bridge phenomenon of the heat conveying channel in the support seat can be effectively avoided, and the effect of saving heat energy is obvious.

Description

technical field [0001] The invention relates to a heat-insulation board, in particular to a high-strength composite heat-insulation board in which a board material and a steel plate are bonded together using a phenolic epoxy resin material as a base material. Background technique [0002] At present, steel baffles are installed on the outer wall of the heat transfer pipeline, and the baffle cooperates with the heat insulation material pad in the support seat of the heat transfer pipeline to release the axial stress caused by the thermal expansion and contraction of the pipeline. At the same time, it plays the role of blocking the transfer of heat from the heat transfer pipe to the foundation support, so as to reduce the heat transfer loss generated by the heat of the heat medium conveyed in the pipe through the fixed steel baffle on the pipe wall to the support seat, that is, heat bridge loss. The main reason for the heat bridge loss of the heat transfer pipeline is that ...
