Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a building composite material structure. Background Art

[0002] As global climate change becomes increasingly severe, the construction industry needs to adopt a more environmentally friendly and sustainable development strategy. Another major challenge facing the construction industry between 2023 and 2024 is how to reduce carbon emissions and energy consumption. As people pay more and more attention to environmental protection and health, the construction industry needs to gradually turn to low-carbon building fields such as green buildings, energy-saving buildings and smart buildings to fundamentally reduce energy consumption and carbon emissions during building operations. At the same time, the construction industry also needs to strengthen cooperation with upstream and downstream companies in the relevant industrial chain to jointly promote the development of the low-carbon construction industry and save energy and reduce consumption in production.

[0003] At present, aluminum foil is easy to wrinkle, thin and easy to be damaged during the production process. After being covered with glass fiber during the production coating process, it causes bulging and bubbles around the glass fiber yarn. After being covered with EVA foam, it causes intermittent damage due to unevenness of the bulging area, separation gaps, etc. over time, weathering in harsh climates, and external factors such as sunlight environment, affecting the normal use cycle effect. Therefore, it is necessary to design a new building material and its preparation method to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a building composite material structure and a preparation method thereof to solve at least one technical problem existing in the above-mentioned prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A building composite material structure comprises a surface material layer, a first adhesive layer, an electroplating layer, a second adhesive layer, a glass fiber layer, a third adhesive layer, a base material layer and an EVA layer, wherein the surface material layer and the electroplating layer are connected via the first adhesive layer, the glass fiber layer is connected to the electroplating layer via the second adhesive layer, the glass fiber layer is connected to the base material layer via the third adhesive layer, and the EVA layer is attached to the base material layer.

[0007] Preferably, the surface material layer is made of aluminum foil.

[0008] Preferably, the material of the electroplating layer is an aluminum-plated film.

[0009] Preferably, the material of the glass fiber layer is a cotton mesh.

[0010] Preferably, the material of the EVA layer is EVA foam.

[0011] Compared with the prior art, the building composite material structure provided by the utility model has the following beneficial effects:

[0012] 1. The utility model avoids coating process loss and greatly improves production efficiency.

[0013] 2. The utility model effectively increases the service life of the product in adverse climates.

[0014] 3. When the utility model peels off the base material, the tensile and tearing resistance of the surface material is enhanced, the improved client and EVA are more flat and the adhesion is stable.

[0015] 4. The utility model solves the problem that the aluminum foil is easy to wrinkle, thin and easy to be damaged during the production process. After being fitted with the glass fiber during the production coating process, the glass fiber wire is bulged and has bubbles. As a result, after being fitted with the EVA foam, the foil is intermittently damaged due to the unevenness of the bulging part, separation gaps, etc. over time, weathering in bad climates, and external factors such as sunlight, affecting the normal use cycle. The product has a wide range of uses, such as wall protection and warmth preservation in the construction industry, electrical insulation and thermal insulation of water pipes and air-conditioning pipes.
