Embodiment 1
[0029] Embodiment 1, the preparation of rubber reinforced cement functional composite material
[0030] Specimen target density: 1500kg / m 3 , Weight: 144 grams, water-cement ratio: 0.25, rubber particle size: 1mm, pressing pressure: 5MPa.
[0031] Raw materials: the ratio of cement and rubber weight and number is 90: 10, wherein, cement 129.6 grams, rubber granule (derived from waste rubber tires) 14.4 grams, coupling agent polyisocyanate (polyether having added polyisocyanate weight 5% as kneading Chain agent, purchased from Yantai Wanhua Group) 2.88 grams (20% of the rubber particle weight), 32.4 grams of water. The cement is made of ordinary Portland cement with a label of 42.5.
[0032] Preparation process: 1) Compounding: Add 10% acetone to polyisocyanate-polyether and mix well; 2) Sizing: Pass the prepared coupling agent through a high-pressure pump gun, and evenly spray the coupling agent on the surface of the rubber particles , aged for half an hour; 3) mixing: the ...
