Composite Thermal Insulating Material
Summary:
Non-combustible, waterproof, sound- and thermal-insulating composite material on silicate basis has been developed in Bulgarian research institute. Product is ecological, durable and resistant to temperature fluctuations. The material is prepared from granules made of glass waste. The research team is looking for collaboration with manufacturing companies for commercialization of the product via a commercial agreement with technical assistance.
Description:
The proposed composite material, elaborated by a Bulgarian research organization is non-combustible, waterproof, sound- and thermal-insulating. The composite material consists of expanded glass granules (diameter 5 - 20 mm), glued together by self-bonding water dispersed colloid system on silicate basis. The material has thermal conductivity coefficient a = 0.050 - 0.055 W/mK, sound absorption 30 - 40 dB, bulk density from 180 to 220 kg/m3 and compressive strength 4 - 5 MPa. The composite material is produced in blocks, of which the needed element is cut out by conventional tools. It can be applied to isolate the spaces around windows and doors to ensure fire security as per the applicable regulations.
The technology for producing products of expanded glass granules is simple and cheaper than the classical expanded glass. A variety of products with different shape and function can be obtained: plates, pipes, blocks, panels, etc.
The technology consists of three stages - preparation of the raw material of glass waste, expanding of the granules in horizontal furnace or inclined rotary furnace, production of the final elements.
The team members offer technical co-operation to engineering and manufacturing companies interested in production of construction materials and commercialization. The proposed collaboration type is commercial agreement with technical assistance.
Advantages and Innovations:
The technology for producing the material is simple and cheap and easy to be applied.
The composite material is non-combustible, waterproof, sound- and thermal-insulating.
Stage of Development:
Prototype available for demonstration
IPs:
Patent(s) applied for but not yet granted
