Abstract

The invention provides a preparation method of a high performance modified phenolic resin refrigeration house insulation board. The preparation method comprises following steps: step one, dissolving phenolic resin into ethanol under a heating condition, adding melamine cyanurate, nepeta oil, and dodecyl ethyoxyl sulfobetaine, stirring, mixing, cooling, sequentially adding sodium citrate, calendulaextract, and nano diatomite, stirring, mixing, extruding, and cutting to obtain modified phenolic resin; step two, weighing raw materials; step three, evenly mixing modified phenolic resin and sericite powder at a high speed, adding a hydrocarbon composition, sodium dioctyl sulfosuccinate, and a foaming agent, and stirring to obtain a mixture (A); and step four, adding a curing agent into the mixture (A), stirring, transferring the mixture (A) to a mould, foaming, moulding, and demoulding to obtain the insulation board. The preparation method has the advantages of simple operation and good raw material compatibility. The prepared insulation board has the advantages of good fire resistant property, excellent waterproof property, good anti-aging performance, and low heat conductivity coefficient, and has a long service life in a damp environment.

Description

technical field [0001] The invention relates to the technical field of insulation board materials, in particular to a preparation method of a high-performance modified phenolic resin cold storage insulation board. Background technique [0002] Cold storage insulation board is a kind of insulation board used in cold storage. It can ensure that the products in the cold storage are kept in a specific low temperature environment for a long time, thereby ensuring the freshness of the products and preventing the products from rotting due to excessive temperature. Therefore, the insulation board of the cold storage The thermal insulation effect is one of the important indicators for evaluating the performance of the cold storage insulation board. At present, the commonly used cold storage insulation boards are mainly products made of phenolic resin or polyurethane, but the flame retardant effect of polyurethane insulation boards is not ideal, and a large amount of smoke will be gen...
