Embodiment 1
[0035] A kind of composite material, concrete preparation method is as follows:
[0036] 1) Weigh 30kg of silicate microcrystalline ceramics, 60kg of zinc oxide (fineness ≥ 800 mesh), 2kg of montmorillonite, and 2kg of isopropyl triisostearyl titanate (TTS), and knead each component In the kneader, knead for 20 minutes under the conditions of kneader stirring blade rotation speed 1000 rpm and kneader temperature 100°C, then discharge and cool to room temperature;
[0037] 2) The weight components are polypropylene (PP) 100kg, maleic anhydride functionalized EPDM rubber (EPDM) 5kg, silicone powder 2kg, antioxidant 1010 0.4kg and other components are mixed, and taken out from the mixture 75kg, and 20kg of the composite material prepared in step 1 are put into a high-speed kneader for high-speed blending. The speed of the high-speed kneader is 1000 rpm, the kneading temperature is 80°C, and the kneading time is 10 minutes, then the material is discharged to form a mixture, and c...
Embodiment 2
[0040] A kind of composite material, concrete preparation method is as follows:
[0041] 1) Weigh 30kg of silicate microcrystalline ceramics, 60kg of zinc oxide (fineness ≥ 800 mesh), 2kg of montmorillonite, and 2kg of isopropyl triisostearyl titanate (TTS), and knead each component In the kneader, knead for 20 minutes under the conditions of kneader stirring blade speed 1000 rpm and kneader temperature 110°C, then discharge and cool to room temperature;
[0042] 2) The weight components are polypropylene (PP) 100kg, elastomer graft toughening agent 5kg, silicone powder 3kg, antioxidant 1010 0.5kg and other components are mixed in proportion, take out 70kg from the mixture and step 30kg of the compound material prepared in 1 was put into a high-speed kneader for high-speed blending. Then the speed of the high-speed kneader is 1000 rpm, the kneading temperature is about 80°C, and the kneading time is 10 minutes, then the material is discharged to form a mixture, and cooled to ...
