DEG C hereinafter, itself and the resistance to low temperature that plastics can be improved after acrylic resin blending and modifying.
The melt flow rate of the low viscosity acrylic resin is 200~300g/10min, can be with poly- to benzene two
Formic acid glycol ester resin and polyimide resin are perfectly compatible.
The coupling agent selection KH-560 or similar substitute.
Preferably, the antioxidant is aromatic amine and/or hindered phenol；The auxiliary antioxidant be phosphite ester and/or
Monothioester；So as to rapid peroxynitrite decomposition compound, while also there is preferable compatibility with resin.
Preferably, the fire retardant be halogen-free type metal hydroxide combustion inhibitor, low cigarette, it is nontoxic, can neutralize it is burned
Acidity, corrosive gas in journey are a kind of environment-friendly fire retardants.
The present invention also provides the preparation methods of above-mentioned modified rotational moulding PP Pipe Compound, include the following steps：
Step 1：After calcium carbonate superfine powder, coupling agent, main anti-oxidant, auxiliary antioxidant and fire retardant are mixed, it is warming up to
50~80 DEG C keep the temperature to obtain the first mixture；
Step 2：Low viscosity acrylic resin, pet resin and polyimide resin are melted
It is stirred 20~30min in a high speed mixer with the first mixture mixture after blending；
Step 3：Through extruder, high temperature is squeezed out at 150~200 DEG C, it is cooling after granulating and forming to obtain the final product.
Beneficial effect：
The modified rotational moulding PP Pipe Compound of the present invention is using low viscosity acrylic resin, pet resin and gathers
Imide resin blending and modifying is added calcium carbonate superfine powder and assigns the resistance to height of plastics to improve the wearability and resistance to low temperature of plastics
Warm nature energy, and significantly improve the impact resistance of plastics.
