Embodiment 1
[0021] The following section of this example describes the formulation of a continuously oriented glass fiber reinforced unsaturated polyester sheet molding compound:
[0022] The various components of the present embodiment and their mass parts are: 20 parts of o-phthalic resin; 7 parts of polystyrene; 15 parts of 25.4mm chopped glass fiber; 8 parts of continuous oriented glass fiber; 10 parts of calcium carbonate; 35 parts of mixed aluminum hydroxide of 25 μm and 2 μm, the mixing ratio is 4:1; 0.5 parts of TBPB; 2 parts of styrene; 0.5 parts of MgO; 1 part of zinc stearate, 0.03 parts of p-benzoquinone, Germany BYK The amount of BYK-996 produced was 0.97 parts.
[0023] The following sections of this example describe the process for making a continuously oriented glass fiber reinforced unsaturated polyester sheet molding compound:
[0024] The above-mentioned components must be strictly metered and fully mixed before being coated on the supporting film of the tablet machine...
Embodiment 2
[0032] The difference between this embodiment and embodiment 1 is:
[0033] The various components of the present embodiment and their mass parts are: 18 parts of m-benzene resin; 10 parts of polyvinyl acetate; 20 parts of 12.7mm chopped glass fiber; 5 parts of continuous oriented glass fiber; 32 parts of calcium carbonate; 10 parts of mixed aluminum hydroxide of 25 μm and 2 μm, the mixing ratio is 1:1; 0.5 parts of TBPB; 2.5 parts of styrene; 0.5 parts of MgO; 1 part of zinc stearate, BYK-996 produced by BYK, Germany The dosage is 0.5 parts.
[0034] Each component must be strictly measured and fully mixed in advance before being coated on the supporting film of the tablet machine, and then becomes a paste mixture (resin paste).
[0035] Its preparation method is identical with embodiment 1.
Embodiment 3
[0037] The difference between this embodiment and embodiment 1 is:
