Embodiment 1

[0027] exist figure 2 Among them, the glass fiber composite waterproof and vapor permeable membrane in this embodiment has a three-layer structure, including

[0028] 1. The outer first glass fiber cloth layer 1, the thickness of the glass fiber cloth of the first glass fiber cloth layer is: 0.03mm-0.4mm.

[0029] 2. The halogen-free flame-retardant thermoplastic polyurethane waterproof and breathable layer 3 in the middle, and the effective thickness of the halogen-free flame-retardant thermoplastic polyurethane waterproof and breathable layer is: 0.05mm-0.3mm, preferably 0.05mm-0.2mm, the best The ground is 0.05mm~0.1mm. When the thickness is 0.05mm, the vapor permeability effect is the best, but the waterproof effect is relatively poor. When the thickness is 0.3mm, the vapor permeability effect is poor, and the waterproof effect increases.

[0030] Thermoplastic polyurethane (TPU), or TPU, is a new type of organic polymer synthetic material, which belongs to chemical comp...

Embodiment 2

[0045]The difference from Example 1 is that the middle thermoplastic polyurethane waterproof and breathable layer is a film with a thickness of 0.05 mm to 0.3 mm formed by mixing the following materials: 18 parts of ammonium polyphosphate, 10 parts of melamine, 9 parts of pentaerythritol, 63 parts of thermoplastic polyurethane, the four raw materials are granular or powdery, and the weighing ratio is parts by weight. The four ingredients are uniformly mixed with a mixer (particle mixer), and then blown into a film by a film blowing machine (a film blowing machine is a device that heats and melts plastic particles and then blows them into a film) to form a halogen-free flame-retardant thermoplastic polyurethane waterproof breathable layer. Among them, mixer and film blowing machine are existing equipment and can be purchased.

[0046] In this embodiment, glass fiber cloth is a kind of non-combustible material, and the middle layer uses halogen-free flame-retardant thermoplasti...

Abstract

The invention discloses a composite glass fiber waterproof breathable membrane and a preparation method thereof. The composite glass fiber waterproof breathable membrane is of a three-layer structure and comprises a first glass fiber cloth layer which is 0.03-0.4mm in thickness, a thermoplastic polyurethane waterproof breathable layer of which the effective thickness is 0.05-0.3mm, and a second protecting layer which is 0.03-0.4mm in thickness, wherein the three layers are composited through a thermal combination process. As the glass fiber cloth has the characteristic of noncombustiblity and the thermoplastic polyurethane has the characteristics of difficulty in combustion, the membrane is conspicuous in fireproof effect when the front side is baked with fire, and due to improvement of the formula of the middle layer, the fireproof property is further improved, the open fire can be prevented within short time, and certain fireproof property is achieved.

Description

technical field [0001] The invention relates to a waterproof and vapor-permeable film with a waterproof and vapor-permeable function, a preparation method thereof and an application in the construction field. Background technique [0002] In the field of construction, the waterproof and vapor-permeable membrane can be used as a waterproof and vapor-permeable cushion for sloping roofs and a thermal insulation protection layer for building curtain walls, or as an auxiliary waterproof layer for metal maintenance structures. The unique vapor permeability of the waterproof vapor permeable membrane can quickly discharge the water vapor inside the building structure, avoiding the growth of mold in the structure and affecting the indoor environment; it can also strengthen the air tightness of the building and improve the windproof performance of the building, which can help the building to further save energy and reduce property costs. Energy consumption while in use. [0003] At p...
