Embodiment 1 Embodiment 1～6 and comparative Embodiment 1～2

[0050] Step 1) Preparation of polystyrene foam substrate

[0051] 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.

[0052] Step 2) Prepare polystyrene fireproof insulation board

[0053] 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.

[0054] Step 3) prepare polystyrene color steel sandwich panel

[0055] like Figure 1~4 As shown...

Embodiment 6

[0076] 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.

[0077] 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 in structure. 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 external 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 ...

Abstract

The invention discloses a fireproofing and heat-insulating adhesive. The fireproofing and heat-insulating adhesive comprises, 100 parts of a saturated magnesium sulfate solution, 100 parts of magnesium oxide, 100-500 parts of water, 0.05-20 parts of a curing modifier, 0.05-40 parts of a waterproof modifier, 10-70 parts of a flame retardant and 0.5-50 parts of a flame retardant synergist. The fireproofing and heat-insulating adhesive is used for the fireproof coating modification of a polystyrene foam board, so the fireproofing and heat-insulating adhesive penetrates into the polystyrene foam board in order to achieve the purpose of uniform coating modification. A color steel sandwich board produced from the polystyrene fireproofing and thermal-insulating board has the advantages of high bending strength, high compressive strength, good tolerance, good combustion performance, and no collapse in fire scenes.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a fire-proof and heat-preserving adhesive. 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 widely used in large industrial p...
