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

[0014] Embodiment 1: with reference to attached figure 1 and 2 . Polyurethane composite profiles for glass curtain walls, which include glass fibers. The multi-bundle glass fibers are densely distributed to form a profile skeleton 1, and polyurethane resin 2 is compounded with the inside and outside of the profile frame 1 to form a polyurethane profile, that is to say, the profile The molding skeleton 1 is composed of multiple bundles of glass fibers, and the polyurethane resin 2 is completely composited with each glass fiber surface in the multiple bundles of glass fibers, and the glass fibers compounded with polyurethane resin 2 are bonded and cured to form the required The above-mentioned special-shaped profile, that is, the inside and outside of the special-shaped profile skeleton 1 refers to the surface of each glass fiber in the polyurethane special-shaped profile. The polyurethane special-shaped profile is an equilateral profile or an unequal profile or a channel prof...

Embodiment 1-1

[0015] 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

[0016] 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 special-shaped profile consisting of polyurethane resin and glass fibers for a glass curtain wall and a forming method. The profile comprises the glass fibers, the multiple beams of glass fibers are densely covered to form a special-shaped profile skeleton, and the insides and the outsides of the polyurethane resin and the special-shaped profile skeleton are compounded to form the polyurethane special-shaped profile. The profile has the advantages that: 1, the profile has light weight and high strength; 2, the profile has energy conservation and heat insulation properties; 3, the profile is healthy and environmentally-friendly, and has remarkable energy-saving effect; 4, the profile has corrosion resistance, ageing resistance and long service life; 5, the profile has good dimensional stability; 6, the profile has good weather resistance, good high temperature resistance and better low temperature resistance; 7, the insulating performance is good; 8, the shock absorption performance is good; 9, the color is rich, and the polyurethane composite material has high hardness and can be used for coating various coatings and manufactured into profiles of various colors to adapt the purposes of different styles and grades; and 10, the profile has fatigue resistance, and the polyurethane composite material has high fatigue resistance so that safety and reliability of material usage are ensured.

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...
