Abstract

The invention relates to a fire-resistant heat-preservation coating material for pipelines. The material is characterized by comprising the following components in parts by weight: 100 parts of polyurethane resin prepared from polyisocyanate and polyalcohol, 0.1-10 parts of potassium acetate, 0.1-10 parts of a foaming agent, 0.1-10 parts of an organic silicon foam stabilizer and 5-50 parts of a flame-retardant additive, wherein the flame-retardant additive is prepared from ammonium dihydrogen phosphate, hexabromobenzene, zinc borate, antimony trioxide, aluminum hydroxide and wollastonite according to a weight ratio of 1:(1-2):(1-2):1:1:(1-2). The fire-resistant heat-preservation coating material has fire resistance and heat preservation performance, has good usability, and is suitable forcoating the peripheries of pipelines or equipment.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a refractory thermal insulation coating material for pipelines, which belongs to the technical field of thermal insulation. Background technique [0002] At present, people's awareness of energy saving in various production and life is constantly improving, and thermal insulation coating materials are widely used in various industrial pipelines, kilns, buildings, etc. Existing commonly used insulation materials such as asbestos, glass fiber felt or glass fiber cloth, etc., in order to improve the insulation effect, the method of increasing the thickness of the material is mostly used. However, due to the increase in the thickness of the material itself, when the insulation material needs to be coated on the pipe When it is applied, it will affect the coating effect and the number of layers of coating. [0003] In the prior art, aluminum foil has a certain application in thermal i...
