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 conveyor 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 conveyor 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-pressure steam g...

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.

Abstract

The invention relates to the field of insulation board manufacturing, in particular to an additive formula for improving the performance of an insulation board, which comprises P.O525R ordinary Portland cement, graphite powder, glass beads, an organic silicon water repellent, a cement composite early strength agent, silica fume, water, ethylene-vinyl acetate copolymer emulsion, a polyether defoaming agent and a sodium gluconate retarder. The production method for improving the performance of the insulation board comprises the following steps: step 1, pretreating polystyrene foam particles by using phenolic aldehyde epoxy resin; step 2, preparing equipment; step 3, coating an inorganic cementing material on a substrate; and step 4, making the inorganic cementing material permeate the substrate. When the technical scheme is adopted, the strength index of the insulation board can be improved.

Description

technical field [0001] The invention relates to the field of insulation board production, in particular to an additive formula for improving the performance of the insulation board and a production method of the insulation board. Background technique [0002] Modified polystyrene board, or insulation board, is a kind of low-density EPS substrate (made of polystyrene foam particles, hereinafter referred to as substrate) and inorganic gelling material, which is uniformly infiltrated, cured and dried. It is a new type of thermal insulation material with thermal insulation and fire rating A2. [0003] The inorganic gelling materials of the current thermal insulation board usually include Portland cement, organosilicon water repellent, cement composite accelerator, fly ash, water and ethylene-vinyl acetate copolymer emulsion. The strength index of the insulation board obtained by infiltration is relatively poor, and the product quality of the insulation board cannot be guarantee...
