A heat-insulating and heat-preserving light-transmitting board, its preparation method and application

Abstract

The invention discloses a heat-insulating and heat-preserving light-transmitting board, its preparation method and application, comprising: two substrates arranged at intervals relative to each other, and a plurality of through holes are oppositely arranged on the two substrates; several isolation rings are located on the two substrates. Between, the spacer rings are arranged around the periphery of each set of opposite through-holes, separating each set of through-holes from the space between the two substrates, at least one set of through-holes in the cavity It is filled with a light-transmitting body; a thermal insulation layer is located between the two substrates except for the through hole and the isolation ring. The thermal insulation and light-transmitting board has good thermal insulation performance, light transmittance and structural strength, is safe and light to use, has a long service life, is easy to process and manufacture, and has high application value, and is especially suitable for the field of building materials.

AI Technical Summary

Problems solved by technology

At present, the widely used insulation boards include foamed polyurethane, foamed polystyrene and inorganic insulation boards, which are difficult to meet the requirements of light weight, high strength and light transmission.

[0003] In terms of light transmission, the currently widely used light-transmitting panels are mainly glass and polymer light-transmitting panels; glass has the following problems: 1: It is fragile and unsafe, and its lifespan is not long due to its fragility, which is likely to cause public safety problems; 2. : Light pollution, the noise light generated by glass reflection, can cause dizziness, temporary blindness, and accidents often occur; 3: The glass itself does not have good structural strength, so it needs to design a strong support structure, which increases its installation. Manufacturing cost, the existing glass generally makes up for these defects by tempering, laminating, and thickening, which not only increases its own weight but also increases the cost, but still cannot solve the above problems well

Polymer light-transmitting boards, including acrylic boards, PC boards and ABS boards, are light in weight, but have low structural strength and are easy to bend and deform. Some polymer materials have a large thermal expansion coefficient, and boards with larger areas are prone to deformation when the temperature changes sharply. Deformation or even cracking occurs, and the scope of application is obviously limited

In addition to the above defects, the existing light-transmitting panels are difficult to achieve heat insulation and cannot meet the energy-saving needs of buildings.
