Problems solved by technology

Its disadvantages: first, it has a large proportion and weight, which increases the weight of the entire glass curtain wall; second, it has poor heat insulation. Since metal is a heat conductor, although it has a supporting role, it also has a good effect of heat conduction, so it will It is used in the glass curtain wall, not only does not have the effect of heat insulation, but has a heat conduction effect, which greatly reduces the heat insulation and heat preservation effect of the glass curtain wall

Embodiment 1

[0020] Embodiment 1: with reference to attached Figure 1-7 . Polyurethane composite profiles for glass curtain walls, which include glass fibers, the multi-bundle glass fibers are densely covered to form the profile skeleton 1, or the profile skeleton is composed of multiple bundles of glass fiber dense layers and glass fiber mat 101, and the polyurethane resin 2 and the profile The inside and outside of the profile skeleton 1 are composited to form a polyurethane profile, that is to say, the forming frame 1 of the profile is composed of multiple bundles of glass fibers densely covered or composed of multiple bundles of glass fiber dense layers and glass fiber mat 101, polyurethane resin 2 and multiple bundles Each glass fiber surface in the glass fiber composition is completely compounded and the glass fibers compounded with polyurethane resin 2 are bonded and solidified to form the required profile, that is, the inside and outside of the profile skeleton 1 refers to the pol...

Embodiment 1-1

[0021] Example 1-1: On the basis of Example 1, 35%-40% polyurethane and 60%-75% glass fiber can be pultruded polyurethane profiles, which have better physical, mechanical and mechanical properties.

Embodiment 1-2

[0022] Example 1-2: On the basis of Example 1, 30%-35% polyurethane and 65%-70% glass fiber can be pultruded polyurethane profiles, which have good physical, mechanical and mechanical properties.

Abstract

The invention relates to a polyurethane composite material special-shaped section for a glass curtain wall and a forming method, wherein the polyurethane composite material special-shaped section is made of polyurethane resin and glass fibers. The polyurethane composite material special-shaped section comprises the glass fibers, multiple beams of glass fibers are densely distributed to form a special-shaped section framework, and the polyurethane resin is compounded with the inner surface and the outer surface of the special-shaped section framework to form the polyurethane special-shaped section. The polyurethane composite material special-shaped section has the advantages that firstly, weight is light and strength is high; secondly, energy conservation and heat insulation are realized; thirdly, healthful, environment-friendly and energy-saving effects are remarkable; fourthly, corrosion resistance and ageing resistance are high and the service life is long; fifthly, dimension stability is good; sixthly, weather resistance is good and high temperature resistance and low temperature resistance are better; seventhly, insulation property is good; eighthly, shock absorption property is fine; ninthly, polyurethane composite material special-shaped section is colorful, a polyurethane composite material is high in hardness, and various coatings can be coated on the polyurethane composite material, so that sections in various colors are manufactured to meet requirements of application in different styles and grades; and tenthly, fatigue resistance of the polyurethane composite material is quite high, so that service safety and reliability of the material are guaranteed.

Description

technical field [0001] The invention relates to a polyurethane composite material special-shaped profile for a glass curtain wall with good supporting strength, light weight and heat insulation effect and a molding method, belonging to the field of composite profile manufacturing. Background technique [0002] At present, among the architectural glass curtain walls popular in the market, the special-shaped profiles used are all metal special-shaped profiles, mainly aluminum alloy. Its disadvantages: first, it has a large proportion and weight, which increases the weight of the entire glass curtain wall; second, it has poor heat insulation. Since metal is a heat conductor, although it has a supporting role, it also has a good effect of heat conduction, so it will It is used in the glass curtain wall, not only does not have the effect of heat insulation, but has a heat conduction effect, which greatly reduces the heat insulation and heat preservation effect of the glass curtai...
