Abstract

The invention belongs to the technical field of building cladding materials, and in particular relates to a production method of a glass reinforced plastic dual-layer hollow plate. The method provided by the invention comprises the following steps of: preparing an outer core material and an inner core material; preparing an outer-layer hollow plate; preparing an inner-layer hollow plate; bonding the outer-layer hollow plate and the inner-layer hollow plate. By the method provided by the invention, the technical problem that a glass reinforced plastic dual-layer hollow plate cannot be produced stably and efficiently in the prior art is solved and the beneficial effects of mechanical continuous formation, simplified working procedures, high production efficiency and stable product quality are achieved.

Description

technical field [0001] The invention belongs to the technical field of building envelope materials, and in particular relates to a production method of a glass fiber reinforced plastic double-layer hollow board. Background technique [0002] FRP hollow board is a kind of board that is connected by longitudinally distributed rib plates between two outer panels, and a cavity is formed between the rib plates and the gap between the rib plates. This kind of plate uses the principle of material mechanics to set the structure according to the requirements, and can achieve high mechanical properties with a small amount of material, and has the characteristics of light weight and high strength. Since FRP is a glass fiber reinforced thermosetting resin composite material, it has the advantages of high strength, low density, aging resistance, low thermal conductivity, good light transmission and high flame retardancy. The outstanding performance is light unit weight, high light trans...

Problems solved by technology

But the fact is: since the raw materials of FRP are in the form of liquid and fabric, at the current level of FRP molding technology, the process of directly producing single-layer hollow panels is already very difficult, and it is necessary to produce double-layer hollow panels with more complex structures. more difficult

If manual production is adopted, the quality is unstable, the production efficiency is low, the manufacturing cost is high, and the product does not have market value

[0004] It can be seen that although double-layer FRP hollow panels have good energy-saving properties and can become a high-energy-saving light-transmitting building envelope material, there is no product for practical use due to the limitations of current manufacturing technology and process level.
