Embodiment 1
[0028] A production method for improving the performance of the insulation board, comprising the steps of:
[0029] Step 1: After pretreating the polystyrene foam particles with novolac epoxy resin, pressing the polystyrene foam particles to form a substrate;
[0030] Step 2: Prepare as figure 1 The insulation board production equipment shown includes a frame, a conveying mesh belt 1, a discharge trough 2, a pressing unit and an adsorption unit. The frame is equipped with a driving roller and a driven roller, and the conveying mesh belt 1 is set on the driving roller. And on the driven roller, the frame is fixed with a servo motor by bolts, the output shaft of the servo motor is welded coaxially with the driving roller, and the model of the servo motor can be selected as MR-J2S-100A.
[0031] The discharge chute 2 is fixedly installed on the frame by bolts, and the discharge chute 2 is located above the conveyor belt 1; the pressing unit includes a press box 4 and a high-pres...
Embodiment 2
[0037] Step 1 of this embodiment and the inorganic gelling material used are the same as Embodiment 1; the difference from Embodiment 1 is that the pressing unit in Step 2 also includes a No. On the frame and located above the conveying mesh belt 1, the pressing box 4 is not fixedly connected with the frame in this embodiment, but the pressing box 4 is welded with the output shaft of the No. 1 cylinder; the pressing box 4 has a through hole, and the material is returned The rod 3 is welded to the frame, the stripping rod 3 passes through the through hole and is slidably connected with the through hole, and the diameter of the stripping rod 3 is 0.1-0.3cm.
[0038] Adsorption unit also comprises No. 2 air cylinders, and No. 2 air cylinders are fixedly installed on the frame by bolts, and No. 2 air cylinders are located in the space surrounded by driving roller, driven roller and conveying mesh belt 1. In this embodiment, adsorption plate 6 is not connected with The frame is fix...
Embodiment 3
[0047] Different from Example 1 and Example 2, the additive formula used to improve the performance of the insulation board includes inorganic gelling materials made of the following quality raw materials: P.O525R ordinary Portland cement 50kg, graphite powder 2kg, glass Chemical beads 2kg, organosilicon water repellent 0.5kg, cement composite early strength agent 2kg, silica fume 3kg, water 20kg, ethylene-vinyl acetate copolymer emulsion 5kg, polyether defoamer 0.1kg, sodium gluconate retarder dose 0.02kg.
