Aluminum foil woven fabric and preparation method thereof

Abstract

The invention discloses an aluminum foil woven fabric which consists of an upper aluminum foil layer, a flame retardant adhesive layer, a flame retardant woven fabric layer, a film lamination layer and a lower aluminum foil layer which are arranged in sequence from top to bottom, wherein the upper and lower aluminum foil layers are high-purity aluminum foils with the aluminum content of 99 percent; the flame retardant adhesive layer is calcium carbonate-added polyurethane composite glue; the flame retardant woven fabric layer is a low-pressure high-density polyethylene woven fabric; the film lamination layer consists of low-density polyethylene particles; the upper surface of the flame retardant woven fabric layer is compounded with the upper aluminum foil layer through the polyurethane composite glue; the lower surface of the flame retardant woven fabric layer is compounded with the lower aluminum foil layer through the melted low-density polyethylene particles in an adhered manner. According to the aluminum foil woven fabric prepared through the method, on the premise of not affecting the compound fastness and the physical performance of the material, the flame retardancy of the whole material is improved, and heat insulation and preservation of buildings home and abroad and flame retardancy of special packaging materials are met; the aluminum foil woven fabric is heat-insulated, waterproof, breathable and reflexible, can meet a heat insulation requirement, and is wide in application range and high in economical benefit.

Description

Technical field: [0001] The invention relates to an aluminum foil woven cloth and a preparation method thereof. Background technique: [0002] Traditional aluminum foil woven cloth composite materials are mainly used for building heat insulation materials and mechanical packaging, etc. In the process of traditional laminating and laminating, due to the high temperature laminating of 330 ° C, the performance of HDPE woven cloth has been affected to a certain extent, so that after laminating The material is brittle and hard, and the tear resistance and puncture resistance are significantly reduced. Its flame retardant effect does not meet the requirements of Australia, the United States and the European Union, which limits the application range and economic benefits. On this basis, there are coatings The composite improvement is glue dry composite, but the aluminum foil woven fabric with this structure has the disadvantages that it is not environmentally friendly, and its wate...

Problems solved by technology

[0002] Traditional aluminum foil woven cloth composite materials are mainly used for building heat insulation materials and mechanical packaging, etc. In the process of traditional laminating and laminating, due to the high temperature laminating of 330 ° C, the performance of HDPE woven cloth has been affected to a certain extent, so that after laminating The material is brittle and hard, and the tear resistance and puncture resistance are significantly reduced. Its flame retardant effect does not meet the requirements of Australia, the United States and the European Union, which limits the application range and economic benefits. On this basis, there are coatings The composite improvement is glue dry composite, but the aluminum foil woven fabric with this structure has the disadvantages that it is not environmentally friendly, and the waterproof and breathable performance is not ideal.
