Polystyrene color steel sandwich panel and preparation method thereof

Abstract

The invention discloses a polystyrene color steel sandwich panel. The polystyrene color steel sandwich panel comprises a core board, wherein the core board is a polystyrene fireproof thermal insulation board; two color steel plates respectively bonded to both sides of the polystyrene fireproof thermal insulation board; two side plates and two sealing plates respectively bonded to the two long sides and the two short sides of the polystyrene fireproof thermal insulation board. A fireproof thermal insulation adhesive is used for fireproof coating modification of a polystyrene foam board, so thatthe fireproof thermal insulation adhesive penetrates the polystyrene foam board to prepare the polystyrene fireproof thermal insulation board. The polystyrene color steel sandwich panel prepared by using the polystyrene fireproof thermal insulation board has the advantages of high bending strength, high compressive strength, good endurance, good combustion performance and no collapse in a fire field.

Description

technical field

[0001] The invention belongs to the technical field of fire protection, and in particular relates to a polystyrene color steel sandwich panel and a preparation method thereof. Background technique

[0002] The color steel sandwich panel is made of color-coated steel plate as the surface material, polystyrene foam, polyurethane foam, phenolic foam, glass wool, rock wool as the core material, and heat-pressurized and compounded in the continuous molding machine with heat-curing adhesive. Ultra-light construction panels. The color steel sandwich panel has light weight (1 / 20 to 1 / 30 of the weight of the concrete roof), thermal insulation (the thermal conductivity of the core material is ≤0.041W / m k), high strength, bending and compression resistance, With the characteristics of fast construction speed and bright color, it is a new type of enclosure structure material integrating load-bearing, heat preservation, waterproof, and fireproof decoration. It has been w...

[0040] Step 1) Preparation of polystyrene foam substrate

[0041] Using polystyrene pre-expanded particles with a density of 5-15g / L as raw material, the steam penetration pressure P 1 MPa, steam penetration time is t 1 Prepare polystyrene foam sheets.

[0042] Step 2) Prepare polystyrene fireproof insulation board

[0043] The polystyrene foam board was placed in the fireproof coating modification equipment, and then the fireproof and thermal insulation adhesive formulated in Table 2 was added to the P 2 Added under high pressure of MPa into the fireproof coating modification equipment placed polystyrene foam board, and then in P 3 Standing time under MPa pressure t 2 , so that the fireproof and thermal insulation adhesive penetrates into the polystyrene foam board, so as to carry out coating modification, and then curing molding time t 3 , get EPS fire insulation board.

[0044] Step 3) prepare polystyrene color steel sandwich panel

[0045] Such as Figure 1~4 As sh...

[0066] In Example 6, since no heat-insulating additive and infrared opacifying agent were added, the fire-proof adhesive had only a fire-proof effect and no heat-insulating function, and could not exert a synergistic effect of heat-insulating with the EPS foam board. The thermal conductivity of 1-5 fireproof and thermal insulation adhesives is relatively large under the same specific gravity.

[0067]In terms of the preparation of color steel sandwich panels, the present invention adopts the integrated combination of grooved side panels, grooved sealing panels, and upper and lower panels structurally. When the surface of the sandwich color steel plate is stressed, due to the and the integrated reinforcement of the edge of the core plate, and the groove structure of the side plate and the sealing plate acts as an outer support frame, which further improves the bending strength of the sandwich color steel plate when the surface is stressed; on the other hand, due to the core of t...
