Abstract
The invention relates to a small-dose polyurethane pouring process of a curtain wall sandwich plate. The small-dose polyurethane pouring process comprises the following steps: setting the flow of two polyurethane raw materials output by a gear pump according to the using amount of the polyurethane, and spraying small-dosage polyurethane liquid in the two polyurethane raw materials in the two side ends of the curtain wall sandwich plate from the discharge opening spray pipe of a raw material mixed head through compressed air; using a plastic lateral edge banding belt and a sponge belt to be spray pipe sealed on the two sides of the curtain wall sandwich plate, and sealing the small-dosage polyurethane liquid in the space formed by an upper metal plate, a lower metal plate, a core material, the plastic lateral edge banding belt and the sponge belt; using a mould to clamp the plastic lateral edge banding belt and the sponge belt between the upper metal plate and the lower metal plate; carrying out foam forming on the small-dosage polyurethane liquid in the space. Through accurate flow control, the reaction of polyurethane raw materials is balanced and stabilized, the foaming space of polyurethane is reduced, the utilization rate of the core material is increased, the phenomenon of cold bridge can be effectively prevented, and the curtain wall sandwich plate is enabled to have good fire resistance.
Description
Technical field:
The present invention relates to a kind of curtain wall clip central layer production technology, relate in particular to the low dose of polyurethane casting craft of a kind of curtain wall clip central layer.
Background technology:
Existing curtain wall clip central layer production line, because casting craft is too simple, low dose of polyurethane foam technology is immature, causing core is not integer root and need the manual size needing that last root sliver is cut in process of production, and core is filled not tight, sheet material integral rigidity and thermal and insulating performance are not good enough, easily cause cold bridge phenomenon.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of curtain wall clip central layer low dose of polyurethane casting craft, with energy-conservation human and material resources, improve globality, tightness, watertightness, rigidity and the adhesion stress of sheet material splicing position, strengthen integral rigidity and the thermal and insulating performance of curtain wall clip central layer, overcome the existing curtain wall clip central layer common quality defect that metal sheet is easy and core is peeled off in carrying, installation process.
For solving the problems of the technologies described above, the invention provides the low dose of polyurethane casting craft of a kind of curtain wall clip central layer, fill for two side spaces of curtain wall clip central layer being realized to low dose of polyurethane foam, described curtain wall clip central layer upper and lower surface is metal pressing plate, centre is bonded with core, it is characterized in that, comprise the following steps:
The first step, the flow of setting two kinds of raw materials of gear pump output polyurethane according to polyurethane consumption sprays low dose of polyurethane liquid by the discharging opening jet pipe of raw material mixing head by two kinds of raw materials of described polyurethane by compressed air in described curtain wall clip central layer two side ends;
Second step, uses plastic side to be encapsulated in respectively described curtain wall clip central layer both sides to edge bonding belt 3 and sponge strip 4, described low dose of polyurethane liquid is sealed in the space 1 being formed to edge bonding belt 3 and sponge strip 4 by described upper and lower metal sheet 6,5, core 2 and plastic side;
The 3rd step, use a mould by described plastic side between edge bonding belt 3 and sponge strip 4 and described upper and lower metal sheet 6,5 clamp;
The 4th step, under specific environment, described low dose of polyurethane liquid is at the interior foaming in described space 1.
The present invention has improved globality, tightness, watertightness, rigidity and the adhesion stress of sheet material splicing position, strengthen integral rigidity and the thermal and insulating performance of curtain wall clip central layer, overcome the existing curtain wall clip central layer common quality defect that metal sheet is easy and core is peeled off in carrying, installation process.
