Embodiment 1

[0059] The polyurethane material for curtain wall described in this embodiment includes 50 parts of bicomponent fibers, 50 parts of polyol, 70 parts of polyisocyanate, 0.1 part of catalyst, 0.1 part of foaming agent, and 0.1 part of foam stabilizer in terms of mass fraction. parts, 5 parts of flame retardants, 15 parts of colorants, 10 parts of antistatic additives, 40 parts of sound-absorbing materials, 5 parts of preservatives, and 50 parts of water.

[0060] When the bicomponent fibers are side-by-side bicomponent fibers, the side-by-side bicomponent fibers are carbon fiber-polyurethane fibers;

[0061] The polyol is a polyether polyol; the catalyst is an amine catalyst; the foaming agent is monofluorodichloroethane; the foam stabilizer is a polyether modified organosilicon surfactant; the coloring The agent is manganese salt; the flame retardant is nitrogen-based flame retardant; the antistatic auxiliary agent is cetyltrimethylammonium chloride; the sound-absorbing materia...

Embodiment 2

[0072] The polyurethane material for curtain wall described in this embodiment includes 80 parts of fibers, 70 parts of polyols, 90 parts of polyisocyanates, 2.5 parts of catalysts, 2.5 parts of foaming agents, 2.5 parts of foam stabilizers, and 2.5 parts of foam stabilizers. 30 parts of burning agent, 50 parts of coloring agent, 30 parts of antistatic additives, 60 parts of sound-absorbing materials, 25 parts of preservatives, and 90 parts of water.

[0073] When the bicomponent fiber is a side-by-side bicomponent fiber, the bicomponent is glass fiber / polyurethane fiber.

[0074] The polyol is a polyester polyol; the catalyst includes an organic metal catalyst; the foaming agent is cyclopentane; the foam stabilizer is a polyether modified organosilicon surfactant; Valence iron salt; the flame retardant is phosphorus flame retardant; the antistatic auxiliary is octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate; the sound-absorbing material is foam metal; the preserva...

Embodiment 3

[0080] The polyurethane material for curtain wall described in this embodiment, in terms of mass fraction, includes 60 parts of bicomponent fibers, 60 parts of polyol, 90 parts of polyisocyanate, 2 parts of catalyst, 2 parts of foaming agent, and 2 parts of foam stabilizer. parts, 10 parts of flame retardants, 30 parts of colorants, 25 parts of antistatic additives, 50 parts of sound-absorbing materials, 10 parts of preservatives, and 80 parts of water. That is, when the flame retardant is 10 parts, the mass ratio of antistatic additives and preservatives is 5:2; when the added colorant is 30 parts, the mass ratio of bicomponent fiber: polyol: polyisocyanate: colorant is 1:1:1.5:0.5.

Abstract

The invention provides a polyurethane material for a curtain wall, which is prepared from the following components in parts by mass: 50 to 70 parts of polyol, 70 to 90 parts of polyisocyanate, 0.1 to 2.5 parts of catalyst, 0.1 to 2.5 parts of foaming agent, 0.1 to 2.5 parts of foam stabilizer, 50 to 80 parts of bi-component fiber, 5 to 30 parts of flame retardant, 15 to 50 parts of coloring agent, 10 to 30 parts of antistatic aid, 40 to 60 parts of sound absorbing material, 5 to 25 parts of preservative and 10 to 500 parts of water. The invention further discloses a building curtain wall profile and a preparation method thereof. The obtained building curtain wall profile has excellent mechanical property, good flame retardant property, shock resistance and sound insulation, normal-temperature forming is achieved, energy consumption in the production process is saved, attractiveness and elegance are achieved, and application and popularization of the environment-friendly curtain wall profile are facilitated.

Description

technical field [0001] The invention belongs to the technical field of new materials, and particularly relates to a polyurethane material for curtain walls, a building curtain wall profile and a preparation method thereof. Background technique [0002] The curtain wall is the outer wall of the building. It is not load-bearing and hangs like a curtain, so it is also called "curtain wall". It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is composed of a panel and a supporting structure system, which can have a certain displacement ability relative to the main structure or a certain deformation ability itself, and does not undertake the role of the main structure. Water tightness, air tightness, shock resistance, thermal insulation, sound insulation, fire prevention, sound absorption, aesthetics, decoration and other aspects have high requirements. [0003] Polyurethane is an organic polymer material with high strength...
