[0014] A high-toughness expanded perlite phenolic resin composite insulation board, made of the following parts by weight (kg) of raw materials: iminooxadiazinedione 0.8, nano silica 1.2, zinc methacrylate 2.8, dicyandiamide 1 , Expanded perlite 55, phenolic resin 40, curing agent HMTA4, steel fiber 2, ethyl orthosilicate 10, 85wt% ammonia water, an appropriate amount of absolute ethanol, deionized water 160, an appropriate amount of n-hexane, nano PTFE 4 , Cumene peroxide 0.1, Trifluoroethyl acrylate 3.
[0015] The preparation method of the heat-expandable perlite phenolic resin composite thermal insulation board with good toughness includes the following steps:
[0016] (1) Mix the expanded perlite with 55 parts by weight of absolute ethanol and deionized water, add nano-silica and zinc methacrylate, stir and heat to 44°C in a water bath, and add 85% by weight ammonia to adjust the pH to 8. Stirring is continued for 10 minutes and then ethyl orthosilicate is added dropwise. Aft...
