Description

Technical field [0001] The invention relates to the technical field of industrial coatings, in particular to a thermal insulation material used for the outer wall of a steel pipeline and a preparation method thereof. Background technique [0002] At present, phenolic thermal insulation materials are widely used as thermal insulation materials for buildings due to their excellent thermal insulation performance, good flame retardant effect and thermal stability. However, conventional phenolic insulation materials have problems such as easy pulverization, poor mechanical properties, and residual free acid curing agents, which limit their popularization and application. [0003] Therefore, it is necessary to propose a new material that can solve the above-mentioned shortcomings of phenolic insulation materials. Summary of the invention [0004] The purpose of the present invention is to provide a thermal insulation material, using the pretreated resin reinforcement as a phenolic foam m...
