Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building boards, in particular to a lightweight and high-strength composite board for construction. Background Art
[0002] Panels are currently the most widely used material, with applications spanning a wide range of fields, including decorative panels, packaging panels, and construction. With the innovation of wall materials and the implementation of energy-saving building policies in my country, the development and application of energy-saving building materials have received widespread attention. Existing residential buildings often utilize reinforced concrete structures for their walls. After the framework is constructed, waterproofing treatment, exterior wall decoration, and interior decoration are applied.
[0003] Most building boards in the existing technology are products with adhesives applied, and the adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and ammonia into the environment, seriously polluting the environment and affecting people's health. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a lightweight and high-strength composite board for construction, which avoids the problem that most building boards in the prior art are products with applied adhesives, and their adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and ammonia into the environment, seriously polluting the environment and affecting people's health.
[0005] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a lightweight and high-strength composite panel for construction, comprising an outer layer panel 1, an outer layer panel 2 being arranged below the outer layer panel 1, a fixed structure being arranged inside the outer layer panel 1 and the outer layer panel 2, the fixed structure being a honeycomb structure, an inner layer panel 1 being arranged between the outer layer panel 1 and the fixed structure, an inner layer panel 2 being arranged between the outer layer panel 2 and the fixed structure, and the outer layer panel 1 and the inner layer panel 1, as well as the outer layer panel 2 and the inner layer panel 2 being connected by MDI glue;
[0006] As an improvement, the materials of the outer layer plate 1 and the outer layer plate 2 are silicon or calcium materials.
[0007] As an improvement, the material of the inner layer plate 1 and the inner layer plate 2 is polystyrene resin.
[0008] The advantages of the present invention compared with the prior art are: by using siliceous and calcareous material plates as the outer layer plate 1 and the outer layer plate 2, the fireproofing, moisture-proofing, sound insulation, insect-proofing and good durability are enhanced; by using MDI glue, the problem that most existing building boards are products with adhesives applied, and the adhesives are usually aldehyde organic adhesives, which can continuously release toxic gases such as formaldehyde, benzene, and ammonia into the environment, seriously polluting the environment and affecting people's health is avoided. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the overall structure of the utility model.
[0010] As shown in the figure: 1. Outer layer panel 1; 2. Outer layer panel 2; 3. Inner layer panel 1; 4. Inner layer panel 2; 5. Fixed structure. DETAILED DESCRIPTION
[0011] The present invention will be described in further detail below with reference to the accompanying drawings.
[0012] When the utility model is implemented, Figure 1 A lightweight high-strength composite panel for construction, comprising an outer layer panel 1, an outer layer panel 2 being disposed below the outer layer panel 1, wherein the outer layer panel 1 and the outer layer panel 2 are made of silicon or calcium materials;
[0013] During the implementation of the present invention, the outer layer board 1 and the outer layer board 2 are made of silicon and calcium materials as the main bonding materials, and are pulped, formed, and accelerated in high-temperature and high-pressure saturated steam to form a calcium silicate gel. The board has the characteristics of fire resistance, moisture resistance, sound insulation, insect resistance, and good durability.
[0014] A fixed structure 5 is provided inside the outer plate 1 and the outer plate 2. The fixed structure 5 adopts a honeycomb structure to reduce the weight of the plate. An inner plate 3 is provided between the outer plate 1 and the fixed structure 5. An inner plate 2 is provided between the outer plate 2 and the fixed structure 5. The material of the inner plate 3 and the inner plate 2 is polystyrene resin.
[0015] During the implementation of the present invention, the inner layer panels 1 3 and 2 4 are made of polystyrene resin or its copolymer as the main component, with a small amount of additives added, and are made of a hard foam material with a closed-cell structure through heating and extrusion. They are not easy to break, are easy to carry and install, and are easy to cut. When used as roof insulation, they do not affect the load-bearing capacity of the structure.
[0016] The outer layer board 1 and the inner layer board 3 as well as the outer layer board 2 and the inner layer board 2 4 are connected by MDI glue. This type of adhesive can be cured at room temperature or by heating, is easy to produce a cross-linked structure, has good heat and solvent resistance, and is more environmentally friendly than trialdehyde glue.
[0017] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
