Abstract

The invention discloses an acid-alkali-resistant compressive thermal insulation material and a preparation method thereof. The acid-alkali-resistant compressive thermal insulation material consists of the following components in parts by weight: 67-72 parts of phenolic resin, 9-12 parts of glass beads, 25-30 parts of polystyrene, 19-23 parts of aluminum silicate, 33-42 parts of polyurethane, 8-14 parts of calcium sulfate, 14-18 parts of aluminum chloride and 26-34 parts of water. The method for preparing the acid-alkali-resistant compressive thermal insulation material comprises the following steps: grinding and crushing, mechanically stirring, cooling and the like. The prepared thermal insulation material has high acid and alkali resistance and compressive property, can tolerate corrosion of acid and alkali and has the compressive strength of 14.6-15.7MPa and heat conductivity coefficient of 0.015-0.019W/(m.K).

Description

technical field [0001] The invention relates to a thermal insulation material and a preparation method thereof, in particular to an acid and alkali-resistant compression-resistant thermal insulation material and a preparation method thereof. Background technique [0002] There are many types of insulation materials with different properties. The thermal conductivity of the thermal insulation material is low and has a good thermal insulation effect. Phenolic resin and polyurethane are two components that are often used in thermal insulation materials. These two components can effectively improve the thermal conductivity of thermal insulation materials, but the thermal insulation materials with phenolic resin and polyurethane as the main components have poor compression resistance, and at the same time Its acid and alkali resistance is also poor, and these defects in performance limit the use of insulation materials with phenolic resin and polyurethane as the main components....
