Energy-saving board and manufacturing method thereof

Abstract

The invention provides an energy-saving sheet material and a manufacturing method thereof. The energy-saving sheet material comprises at least one layer of upper sheet material, at least one layer of lower sheet material, at least one layer of inner sheet material and a plurality of support structures, wherein the upper edge of the upper sheet material and the lower edge of the lower sheet material are respectively straight lines; the inner sheet material is arranged between the upper sheet material and the lower sheet material, and the sheet materials in adjacent layers are separated by the support structures; an exhaust port is formed in the side of the inner sheet material, and is a through groove penetrating through the upper surface and the lower surface of the inner sheet material; the edges of the upper sheet material, the lower sheet material and the inner sheet material are sealed and closed by a sealing material, so that vacuum layers are formed among the sheet materials; an exhaust pipe is arranged in the exhaust port, the open end of the exhaust pipe is positioned on the inner side of the exhaust port, and the closed end of the exhaust pipe is positioned on the outer side of the exhaust port and exists in the space formed between the upper sheet material and the lower sheet material. The energy-saving sheet material is fully planar and is free of structure defect, so that the using strength of the energy-saving sheet material is enhanced.

Description

technical field [0001] The invention relates to energy-saving plate technology, in particular to an energy-saving plate and a manufacturing method thereof. Background technique [0002] Energy-saving panel products can be used in the fields of building doors and windows, and are excellent heat and sound insulation materials. In the past technology, two pieces of flat glass are separated by an appropriate support structure, and the periphery is bonded with an adhesive. The inner chamber uses a vacuum pump to extract gas molecules through a glass exhaust pipe, and puts a getter material in the chamber, so that The internal vacuum pressure range is about 10 -2 ~10 -7 torr. The glass exhaust tube is then fused and severed to form a hermetic seal. [0003] In the prior art, when the glass exhaust pipe is cut off airtight, it is melted by local heating. Because the temperature required for melting glass is very high, the position where the glass exhaust pipe is heated and mel...

Problems solved by technology

However, the accommodation gap on the flat glass weakens the strength of the flat vacuum glass, which is likely to cause structural problems
