Basalt fiber reinforced polyurethane composite door and window section

Abstract

The invention discloses a basalt fiber reinforced polyurethane composite door and window section which consists of the following raw materials in parts by weight: 50 to 80 parts of basalt fibers, 10 to 40 parts of polyurethane resin, 3 to 4 parts of poly butyl acrylate, 3 to 4 parts of bone black, 5 to 15 of parts of calcium carbonate, 0.2 to 0.4 part of disodium octaborate tetrahydrate, 0.1 to 0.3 part of 8-hydroxyquinoline, 2 to 3 parts of polyisoprene, 1 to 2 parts of aluminium triphosphate, 1 to 2 parts of polydimethylsiloxane, 2 to 3 parts of medical stone powder and 1 to 2 parts of performance additive. The basalt fiber reinforced polyurethane composite door and window section disclosed by the invention has the advantages of good heat preservation effect, high intensity, acid and alkali resistance, good aging resistance and the like and can be widely applied to the field of buildings.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a basalt fiber reinforced polyurethane composite door and window profile. Background technique [0002] Now, with the improvement of the quality of human life and the proposal of international energy conservation and emission reduction, the demand for various energy-saving and environment-friendly doors and windows has been increasing day by day. However, the original door and window materials, such as aluminum alloy, stainless steel and other doors and windows, have high heat transfer coefficients, resulting in poor thermal insulation performance, poor energy saving effect, and low corrosion resistance, which can no longer meet the needs of reality. Although the heat transfer coefficient of glass fiber reinforced composite doors and windows is lower, the thermal insulation effect is not very prominent, and the corrosion resistance and aging resistance of glass fiber windows s...

AI Technical Summary

Problems solved by technology

However, the original door and window materials, such as aluminum alloy, stainless steel and other doors and windows, have high heat transfer coefficients, resulting in poor thermal insulation performance, poor energy saving effect, and non-corrosion resistance, which can no longer meet the needs of reality.

Although the heat transfer coefficient of glass fiber reinforced composite doors and windows is lower, the thermal insulation effect is not very prominent, and the corrosion resistance and aging resistance of glass fiber windows still need to be improved.

At the same time, the resin generally used for reinforcement is unsaturated resin. Due to the effect of long fibers, the composite material has high longitudinal strength but weak transverse strength. Mat body needs to be added during production, and the process is cumbersome.
