Embodiment Construction

[0016] The high-efficiency thermal insulation material for building exterior walls of the present invention is composed of a high-barrier film bag and a support, and the support is wrapped in the high-barrier film bag.

[0017] The high barrier film bag includes an inner layer, an outer layer, and an intermediate layer between the inner layer and the outer layer. Among them, the high-barrier film bag includes an inner layer, an outer layer, and an intermediate layer between the inner layer and the outer layer. The inner layer of the high-barrier film bag is a polyethylene heat-seal layer, and the outer layer is alkali-resistant glass fiber mesh cloth. Between the outer layer and the outer layer is an intermediate layer formed by dry compounding of several film barrier materials such as HDPE, LDPE, LLDPE, BOPA, BOPP, EVOH, and AL.

[0018] The support is a mixture of fumed silica, ultra-fine glass fiber and other fireproof materials.

[0019] The production method of the vacuu...

Abstract

The invention relates to a vacuum insulation board for an exterior construction wall and a production method thereof. The insulation board consists of a high-barrier thin film bag and a supporting object. The supporting object is made of a mixture of fumed silica, ultrafine micro-glass fiber and other fireproofing materials. The outer layer of the high-barrier thin film bag is provided with a glass fiber gridding cloth, the inner layer of the high-barrier thin film bag is provided with a PE (Poly Ethylene) heat-seal layer, and the middle layer of the high-barrier thin film bag is provided with a high-barrier thin film made of HDPE (High-Density Poly Ethylene), LDPE (Low-Density Poly Ethylene), LLDPE (Linear Low-Density Poly Ethylene), BOPA (Biaxially Oriented Poly Amide), BOPP (Biaxially Oriented Poly Propylene), EVOH (Ethylene Vinyl Alcohol), AL (Aluminum Leaf) and the like. According to the vacuum insulation board disclosed by the invention, a novel efficient insulation material is provided for the thermal insulation of the exterior construction wall by using the vacuum thermal insulation principle. And the vacuum insulation board has the advantages of environmental friendless, energy conservation, fire prevention and the like.

Description

technical field [0001] The invention relates to a thermal insulation material for building exterior walls, in particular to a thermal insulation board applied to building exterior walls and a production method. Background technique [0002] With the development and progress of society, the increasing consumption of energy and the depletion of resource reserves have become the focus of attention of all countries in the world. Building energy saving is an important measure to alleviate energy shortage and an important topic in the construction industry. With the continuous deepening of energy-saving work in residential construction in my country and the continuous improvement of energy-saving standards, some energy-saving technologies and materials have been vigorously promoted and used in buildings. "Wearing warm coats for buildings can effectively block the heat conduction between indoors and outdoors, thereby reducing the energy consumption required to maintain a normal li...
