Embodiment 1
[0026] Embodiment 1: An economical polystyrene insulation extruded board, including the following components:
[0027]
[0028] Among them, polystyrene particles are composed of polystyrene virgin material, polystyrene recycled material and polystyrene waste, and the mixing ratio is 1:2:2. The antifungal agent is a mixture of 8-hydroxyquinoline copper and ammonium benzoate, and the mixing ratio is 1:1.2. The carrier of the color masterbatch is polyperfluoroethylene propylene.
[0029] The preparation method of economical polystyrene insulation extruded board described in this embodiment comprises the following steps:
[0030] (1) Mix and granulate polystyrene reclaimed material and polystyrene waste material after recovery, add in the mixer together with polystyrene new material, then add benzoyl peroxide, twelve Sodium alkylbenzene sulfonate and benzoyl peroxide, start the mixer to mix the materials, and heat the mixed materials to 150°C, keep stirring for 2 hours, then ...
