[0061] Example 2: Low calorific value thermosetting plastics (LCTC) for underground facilities with different content of process additives
[0062] For different types of inorganic minerals, the addition amount has a great influence on the calorific value of thermosetting plastics, and the particle size directly affects the addition amount of inorganic minerals.
[0063] (1) Weigh the components according to the formula:
[0064] 100 parts of phenolic resin
[0065] Zinc stearate powder 10 parts
[0066] 100μm aluminum hydroxide powder 450 parts
[0067] 3 parts tert-butyl peroxybenzoate
[0068] Magnesium oxide 0.8 parts
[0069] D540 15 copies
[0070] Continuous glass fiber 250 parts
[0071] Measure phenolic resin, D540, zinc stearate micropowder, tert-butyl peroxybenzoate, and aluminum hydroxide micropowder, add them in a high-speed disperser in an orderly manner and mix and disperse for 30 minutes, then measure the thickener and mix and ...
