Detailed Description
Specific embodiments of the present invention are described in further detail below. It should be understood that the detailed description is intended by way of example only and is not intended to limit the scope of the invention.
The environment-friendly type incombustible decorative plate comprises a base layer, a decorative layer arranged on one side of the base layer and a backing layer arranged on the other side of the base layer.
The base layer is made of a plurality of layers of carbon fiber mats impregnated with a fire-resistant material. The length of the carbon fiber should be controlled so that it cannot be too short nor too long, and so that it cannot function as a traction and winding, resulting in a decrease in the strength of the decorative sheet. Too long carbon fibers will affect the mixing of the carbon fibers with the fire-protecting material, resulting in insufficient impregnation and failure of the carbon fibers to achieve the above-described effects. Therefore, the length of the carbon fiber is controlled between 7mm and 14mm, so that the carbon fiber can be fully stirred and mixed by using the existing equipment to form a layered carbon fiber felt, and the aim of fully utilizing the respective advantages of the carbon fiber and the waterproof material is fulfilled. In this embodiment, the weight percentage of the carbon fiber felt in the base layer is 10% -15%, and the weight percentage of the carbon fiber felt must be between 10% -15%, if the weight percentage of the carbon fiber felt is less than 10%, the bending strength of the base layer is significantly reduced, and the strength requirement of the decorative board is not met. Because the base layer is formed by hot-pressing a plurality of layers of carbon fiber mats impregnated with fireproof materials, if the weight percentage of the carbon fiber mats is higher than 15%, the interlayer bonding force in the base layer can be reduced, and the combustion heat value can exceed the standard. It is understood that the other substance of the base layer is the fire-proof material. The choice of impregnating glue is also important in order to achieve the aim of exploiting the respective advantages of the carbon fibres and the fire-protection material as far as possible.
In the fireproof material, the fireproof material consists of a resin formed by blending aqueous epoxy resin, aqueous polyurethane resin and aluminum hydroxide powder. The fireproof material is slurry before impregnation, wherein the important percentage of resin formed by blending the aqueous epoxy resin and the aqueous polyurethane resin is 5-8%, the important percentage of aluminum hydroxide powder is 75-85%, and the balance is water. The aqueous epoxy resin is a stable dispersion system obtained by dispersing an epoxy resin in the form of fine particles or droplets in a dispersion medium having water as a continuous phase. The epoxy resin is a thermosetting resin with a linear structure, so that water can be added for dispersion, chemical crosslinking reaction occurs in a room temperature environment, and the original soluble and fusible property of the epoxy resin is changed into an insoluble and infusible space network structure after the epoxy resin is cured, so that the epoxy resin has excellent performance. Besides the advantages of the solvent type epoxy resin coating, the aqueous epoxy resin has extremely high adhesive force to the carbon fiber, and the cured coating film has excellent corrosion resistance and chemical resistance, small shrinkage, high hardness, good wear resistance and excellent electrical insulation performance. In addition, the aqueous epoxy resin has good environmental protection performance, and also has the advantages of no organic solvent or low content of volatile organic compounds, and no air pollution, thereby meeting the current environmental protection requirement. The aqueous polyurethane resin refers to polyurethane which takes water as a dispersion medium. The polyurethane resin has the characteristics of flexibility and wear resistance and is used for providing toughness for the nonflammable plate. The aqueous polyurethane coating agent is linear, has thermoplasticity and has the characteristics of water resistance, solvent resistance and wear resistance. Therefore, the aqueous epoxy resin and the aqueous polyurethane resin can be used for bonding the aqueous polyurethane together, and the strength of the whole non-combustible plate can be improved. However, the content of the resin formed by blending the aqueous epoxy resin and the aqueous polyurethane resin is not arbitrarily added, and if the weight percentage thereof in the slurry of the fireproof material exceeds 8%, the heat value of the non-combustible plate exceeds the limit value of the non-combustible grade, such as the maximum value of 3.0MJ/kg under the requirement of the non-combustible grade of A2 grade. Exceeding the maximum value of the heating value indicates that the non-combustible sheet is unsatisfactory. And if the weight percentage of the resin formed by blending the aqueous epoxy resin and the aqueous polyurethane resin in the slurry of the fireproof material is lower than 5%, the bonding strength of the multi-layer hot-pressed carbon fiber felt is too low, and delamination is easy to occur in the use process. Meanwhile, in the hot pressing process, the decorative layer and the backing layer are hot pressed, other types of glue are not used for environmental protection, the water-based epoxy resin and the water-based polyurethane resin are used for bonding the decorative layer and the backing layer together, and if the weight percentage of the resin formed by blending the water-based epoxy resin and the water-based polyurethane resin is lower than 5%, the bonding strength between the hot pressed base layer, the decorative layer and the backing layer is too low, and the phenomena of warping, warping and layering are easy to occur.
In the resin formed by blending the aqueous epoxy resin and the aqueous polyurethane resin, the weight percentage of the aqueous epoxy resin is 30-40%, and the important percentage of the aqueous polyurethane resin is 60-70%. The aqueous epoxy resin is used to provide the bonding strength to the base layer, and thus the content thereof should be limited to 30% to 40%, because if the content of the aqueous epoxy resin is less than 30% by weight, it may cause delamination due to insufficient bonding strength between the multi-layered carbon fiber mat and between the carbon fiber mat and the decorative layer and the backing layer. And if the content of the aqueous epoxy resin is too high, it will be extruded to the content of the aqueous polyurethane resin, and if the content of the aqueous polyurethane resin is less than 60% by weight, the toughness of the base layer will be insufficient, and cracks, even cracks, will occur during bending. Therefore, in the resin formed by blending the aqueous epoxy resin and the aqueous polyurethane resin, the important percentage content of the aqueous epoxy resin and the aqueous polyurethane resin should be designed strictly according to the requirements.
The solvents of the aqueous polyurethane and the aqueous epoxy resin are water, so that other solvents which can influence the environment are avoided, volatilization of toxic or harmful solvents is avoided, the aqueous polyurethane and the aqueous epoxy resin are safer and more environment-friendly, the heat value of the unit weight of the aqueous resin is lower, and the bonding strength can be ensured by using enough glue amount.
The aluminum hydroxide powder itself is an excellent fireproof material, and the more the parts, the better the aluminum hydroxide powder should be, but the content of the aluminum hydroxide powder should not exceed 85% in order to make the aluminum hydroxide powder sufficiently dispersible in water. Of course, too low a content will affect the fire resistance, and therefore, the content thereof cannot be less than 75% so that the aluminum hydroxide powder covers each layer of carbon fiber felt with a high probability after the fire-resistant material impregnates the carbon fiber felt.
The decorative layer can be made of any wood fiber such as paper as a decorative material, and various patterns meeting the requirements of users are arranged on the decorative layer so as to adapt to the requirements of the users on the beauty. The decorative layer may also be made of aluminum foil or of embossed aluminum foil.
The backing layer may also be made of aluminum foil, which is provided on the other side of the base layer with respect to the decorative layer. The backing layer is attached to the wall when the non-combustible decorative panel is in use, helping to resist moisture.
During manufacturing, each layer of carbon fiber felt is firstly immersed in the fireproof material slurry, then each layer of carbon fiber felt immersed in the fireproof material slurry is dried, then a plurality of layers of dried carbon fiber felt immersed in the fireproof material slurry are laminated together according to requirements, then a layer of decorative layer and a layer of backing layer are respectively paved on the surface layer and the bottom layer, namely, a plurality of layers of carbon fiber felt immersed in the fireproof material, the decorative layer and the backing layer are respectively dried and then laminated and hot pressed to form the fireproof material. The thickness of the environment-friendly non-combustible decorative plate prepared by the manufacturing method is less than or equal to 0.7mm. Because it is too thick, the toughness is reduced after the aqueous polyurethane and the aqueous epoxy resin are dried, and if the thickness is more than 0.7mm, cracks and even splits are easily generated when bending.

Test results
Compared with the prior art, the environment-friendly type non-combustible decorative plate provided by the invention can withstand high-temperature, high-humidity and high-salt environments by selecting materials used for the base layer, the decorative layer and the physicochemical layer and designing the impregnating solution, and particularly, the base layer is made of carbon fiber and inorganic materials, and the inorganic materials are high-temperature and high-salt resistant materials, so that the environment-friendly type non-combustible decorative plate cannot be deteriorated or corroded in the high-temperature and high-salt environments. In a high humidity environment, the inorganic material still absorbs a certain amount of moisture, but the deformation of the inorganic material is smaller due to the action of the carbon fiber, such as traction or winding, so that the base layer can be prevented from being deformed to cause cracking or edge curling, and meanwhile, the carbon fiber occupies a certain amount, so that the water absorption can be reduced, and corrosion can be resisted. The base layer is not cracked and deformed greatly, the decorative layer on the surface layer is not cracked and deformed, and the decorative layer is in a dry state generally and is not easy to absorb moisture because the decorative layer is positioned on the outer surface, and the decorative layer is not damaged generally in the service life of the decorative plate.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
