Embodiment 1

[0051] The FRP grating hollow panel of this embodiment includes an outer panel 2, a grid 3 and an inner panel 4, and the three are bonded from top to bottom to form a whole.

[0052] The outer panel 2 and the inner panel 4 are glass fiber reinforced plastic rectangular flat plates with the same size. The outer panel 2 and inner panel 4 are preferably made of transparent flame-retardant glass steel plates. The outer panel 2 and inner panel 4 have a length of 6-12m, a width of 0.8-2.4m, and a thickness of 1.2-3.5mm. In this embodiment, both the outer panel 2 and the inner panel 4 are made of transparent flame-retardant glass steel plates with a length of 6m, a width of 1m, and a thickness of 2mm.

[0053] The grid 3 includes several longitudinal ribs 301 and several transverse partitions 302, and the longitudinal ribs 301 and the transverse partitions 302 are rectangular flat plates made of glass fiber reinforced plastic: the length of each longitudinal rib 301 is the same as th...

Embodiment 2

[0057] The difference between the FRP grating hollow panel of this embodiment and the first embodiment is that the exposed surface of the outer panel 2 , that is, the upper surface of the outer panel 2 is covered with an anti-aging film 1 . The anti-aging film 1 is preferably a polyester film with a thickness of 15 μm treated with a corona surface.

Embodiment 3

[0059] The production method of the FRP grid hollow plate described in embodiment 2 specifically comprises the following steps:

[0060] Step (a) Prepare grid 3

[0061] Step (a1) Prepare grid 3 glass steel plate

[0062] Lay a polyester film on the production platform as a carrying process film, and move forward synchronously with the equipment. The thickness of the polyester film is preferably 20 μm; evenly coat the resin glue on the polyester film; then spread the alkali-free Glass fiber felt, the specification of described alkali-free glass fiber felt is preferably 450g / m 2 ; After the alkali-free glass fiber mat is soaked, cover another layer of carrying process film to form a sandwich belt; then gradually run to the oven for heating and curing molding, in this embodiment, the heating temperature is 40 ~ 80 ° C, run The speed is 1.5m / min, and the curing time is 15-20 minutes; remove the polyester film on both surfaces after curing and molding.

Abstract

The invention belongs to the technical field of plates for building containment, and specifically relates to a glass fiber reinforced plastic grating hollow plate and a production method of the glass fiber reinforced plastic grating hollow plate. The glass fiber reinforced plastic grating hollow plate comprises an outside plate, a grating and an inside plate, the grating comprises a longitudinal rib plate and a cross diaphragm plate in latticed structure. The production method comprises the steps of preparing the grating, preparing the inside plate and bonding the grating, preparing the outside plate and bonding the grating and the inside plate, and cutting. The technical problems that the existing glass fiber reinforced plastic hollow plate is easily subjected to the cross shearing strength damage parallel to a panel, the existing glass fiber reinforced plastic production method is low in production efficiency and bad in product stability, are solved. The glass fiber reinforced plastic grating hollow plate provided by the invention is stable in structure, secure in bonding and strong in cross anti-shearing ability. The production method provided by the invention is capable of adopting the intermittent production process to manufacture one by one, and adopting the continuous production process to cut according to the specified size, the production efficiency is high and the product is stable.

Description

technical field [0001] The invention belongs to the technical field of panels for building enclosures, and in particular relates to a fiberglass grating hollow panel and a production method thereof. Background technique [0002] Hollow plate is a kind of plate that uses the principle of material mechanics to make its interior hollow according to certain rules, and uses less material to achieve higher mechanical properties. At present, the common hollow boards are mostly produced by high-temperature extrusion molding processes of thermoplastic resin materials such as polycarbonate (PC), polystyrene (PS), polypropylene (PP) and polyvinyl chloride board (PVC). Due to the deformation and low mechanical strength of thermoplastics after heating, their application in building envelope is limited. As a glass fiber reinforced thermosetting resin composite material, FRP has the advantages of high strength, low density, aging resistance, low thermal conductivity, good light transmissi...
