Pipeline thermal insulation material as well as preparation method and application thereof

Abstract

The invention relates to the field of chemical engineering, and particularly discloses a pipeline thermal insulation material as well as a preparation method and the application thereof. The pipelinethermal insulation material comprises a component A and a component B, the component B is polymerized diphenylmethane diisocyanate, and the raw materials of the component A comprise a plurality of polyols, n-pentane, a catalyst, a foam stabilizer, water and the like; the n-pentane is adopted as a foaming agent, the environment-friendly requirement is met, meanwhile, through selection of polyhydricalcohols and other auxiliaries, when the obtained pipeline heat preservation material is used, formed pipeline heat preservation foam is high in binding power with a base material, excellent in highand low temperature resistance and excellent in heat preservation performance, and the heat preservation using and environment-friendly requirements of a large-caliber pipeline are completely met; thepolyurethane composite material solves the problem that the existing polyurethane composite material for pipeline heat preservation can not completely meet the use performance requirement and the environment-friendly requirement of large-caliber pipeline heat preservation at the same time. The preparation method provided by the invention is simple and has a wide market prospect.

Description

technical field

[0001] The invention relates to the field of chemical industry, in particular to a pipe insulation material and its preparation method and application. Background technique

[0002] With the advancement and development of science and technology, materials with various functions are also widely used in construction. Among them, since pipelines are widely used in liquid and gas transportation network, chemical pipeline insulation engineering, petroleum, chemical industry, central heating heating network, central air conditioning ventilation, municipal engineering and other fields, the insulation treatment of pipelines is very important to ensure its normal use. is of great significance.

[0003] At present, the insulation materials used for pipeline insulation mainly include: rock wool, high temperature resistant glass wool, aluminum silicate, microporous calcium silicate, composite silicate, pipe support, heat shrinkable tape, polyurethane composite material,...
