Abstract

The invention discloses a high-strength thermal insulating epoxy resin composition used for solving the technical problems that the thermal insulating material used by an existing supporting saddle for a heat transport pipeline is not high in strength and is easily subjected to heat bridge transfer. The composition comprises the following substances based on 100 parts by weight: 60-80 parts of epoxy resin, 15-30 parts of glass fiber yarn, 2-4 parts of microporous calcium silicate, 1-3 parts of curing agent, and 1-3 parts of accelerating agent. A reinforced fiber and an epoxy resin based composite material are presoaked in a proportion, hot-pressed, and then prepared to a platy insulation pad or an insulation pad in a needed shape. The composition disclosed by the invention can be applied to the pipeline supporting saddle to function as a part of a bearing and thermal insulating structure of the pipeline supporting saddle so as to effectively prevent and reduce the occurrence of a heat bridge phenomenon on the supporting saddle for the heat transport pipeline, and the energy-saving effect is obvious.

Description

technical field [0001] The invention relates to a high-temperature-resistant and high-strength heat insulation material with a temperature resistance of 150°C, which is mainly used for heat insulation in the support of directly buried heat transmission pipelines or in the support of overhead heat transmission pipelines, and meets the requirements of sliding heat transmission pipelines. The strength requirements and thermal insulation requirements of the heat insulation material for the support or the fixed support of the heat transmission pipeline. Background technique [0002] At present, the fixed support or sliding support of the heat transfer pipeline that transports steam or hot water is generally made of steel. The steam or hot water in the heat transfer steel pipe transfers heat to the support through the baffle plate and the fixed support on it, forming a thermal bridge transfer and causing heat loss. Since the fixed support of the steam or hot water pipeline must...
