[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] In the description of this invention, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper", "lower", "top surface", "bottom surface", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0030] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] Example 1

[0032] This embodiment provides a multifunctional one-piece molded decorative panel, such as... Figures 1-3 As shown: It includes an upper decorative layer 1 and an insulation layer 2; the material of the insulation layer 2 is lightweight concrete, and EPS particles 22 with a surface coating and bonding layer are mixed in the lightweight concrete; the upper decorative layer 1 is located on the top surface of the insulation layer 2, and the upper decorative layer 1 and the insulation layer 2 are integrally formed components.

[0033] EPS particles are polystyrene foam, which is a light-weight high polymer. It is produced by adding a foaming agent to polystyrene resin, heating the polystyrene resin to soften it, and generating gas to make the polystyrene resin into a hard closed-cell foam plastic. It has the characteristics of low water absorption, good thermal insulation, and light weight. When it is mixed into cement, it can be used to produce lightweight concrete with different apparent densities.

[0034] The apparent density of EPS particles is only 7-20 kg / m 3 , and the interface adhesion between the EPS particles and the cement paste is weak, so it is easy to segregate during concrete mixing. The use of a surface modifier to form a coating link layer on the surface of the EPS particles can solve this problem. The surface modifier used in the surface-coated EPS particles 22 of the present application is MSAI 01, which mainly contains ethylene-vinyl acetate copolymer, methacrylic acid, silicone oil, calcium chloride, alkali metal silicate, etc. This product is produced by Xuzhou Moore Engineering Plastics Co., Ltd. MSAI 01 can modify the surface of EPS particles through emulsification, shrinkage, European Union, adsorption, etc. It has the advantages of no shrinkage, no segregation, high flow, no foaming, strong wrapping, etc. It greatly improves the overall performance of lightweight concrete.

[0035] The method of using MSAI 01 to coat the surface of EPS particles with a link layer is to atomize the surface modifier MSAI 01 through equipment, and directly spray the atomized MSAI 01 onto the surface of the EPS particles in the mixing process, so that a layer of molecular chain that can effectively link with the cement base is formed on the surface of the EPS particles.

[0036] After the surface-coated EPS particles 22 are mixed with the cement base, the EPS particles do not sink to the bottom or float to the top, and they are tightly bonded with the cement without peeling off, uniformly distributed in the cement base to form a lightweight concrete insulation layer with stable quality. This greatly improves the performance of lightweight concrete using EPS particles as lightweight aggregate. On the other hand, by using surface-coated EPS particles as lightweight aggregate in cement, the amount of cement used is greatly reduced, and EPS packaging waste can be recycled. EPS particles have good water resistance, thermal insulation, insulation, low moisture absorption, strong shock resistance, etc. The lightweight concrete using surface-coated EPS particles as lightweight aggregate has the engineering characteristics of thermal insulation, shock absorption, shock absorption, size increase, and weight reduction. The use of this material for insulation has the functions of thermal insulation, sound insulation, and fireproofing. The development and performance research of this insulation material and its engineering application exploration not only have important economic and social benefits in the field of construction, but also have important economic and social benefits in reducing environmental pollution and recycling solid waste.

[0037] Therefore, the thermal insulation layer material of the present application, by selecting the superior performance of EPS particles as lightweight aggregate in lightweight concrete, not only maintains the advantages of ordinary polystyrene particle concrete, such as lightweight (density as low as 130 kg / m 3 ), thermal insulation (thermal conductivity as low as 0.043 W / mK), sound insulation, etc.; but also overcomes some shortcomings of ordinary polystyrene particle concrete, such as poor fire resistance, poor construction performance (particle floating, segregation, poor cement combination), etc.; also improves some performance, such as impact sound insulation (weighted normalized impact sound pressure level can reach special level), deformation performance, environmental protection index, etc. The lightweight concrete mixed with the EPS particles with a surface-coated linking layer has better gripping force and adhesion. It has A-grade fireproofing, lightweight thermal insulation, excellent sound insulation and noise reduction performance. The bulk density can reach more than 1 / 10 of the bulk density of traditional concrete, with good anti-stretching performance, low elastic modulus, superior impact resistance, fast construction speed, low comprehensive cost, etc.

[0038] In addition, the integrally formed component is arranged so that the decorative plate of the present application can realize decoration, thermal insulation, heat insulation, fireproofing, sound insulation in one step, solving the subsequent secondary coating decoration engineering of traditional methods after laying the thermal insulation layer, thereby greatly simplifying the installation process, and avoiding air pollution in the secondary coating process. It is practical, safe and environmentally friendly, speeds up the decoration, reduces the consumption of manpower and material resources, and reduces the decoration cost. It is solid and durable, will not fall off due to moisture, and has a longer service life.

[0039] The surface density of the thermal insulation layer 2 of the multifunctional integrally formed decorative plate is ≤90 kg / m 2 , and the bulk density is ≥130 kg / m 3 .

[0040] The thickness of the upper decorative layer 1 of the multifunctional integrally formed decorative plate is 1 cm, and the thickness of the thermal insulation layer 2 is 50-120 mm. The staff can select the thermal insulation layer 2 with a thickness of 50 mm, 75 mm, 90 mm, 100 mm or 120 mm according to the different laying positions.

[0041] The size of the multifunctional integrally formed decorative plate is 1200x2400mm or 1220x2440mm; the specific size can be selected according to the desired laying position, and it can be cut arbitrarily during the laying process to make the laying of the multifunctional integrally formed decorative plate more simple and convenient. In addition, the multifunctional integrally formed decorative plate can also be customized with other sizes according to the use requirements or the selection of customers.

[0042] The insulation layer 2 has a quadrilateral plate structure, with matching protrusions 23 and grooves 24 on its two opposite long ends. Adjacent multi-functional integrated decorative panels are joined and fixed by the cooperation of the protrusions 23 and grooves 24. The tongue-and-groove design makes the installation of the multi-functional integrated decorative panels simpler and faster, improving installation quality. As a further alternative implementation, the two adjacent multi-functional integrated decorative panels are fixed by an adhesive layer 25, which is a sealant. The adhesive layer 25 is placed between the interlocking protrusions 23 and grooves 24. The adhesive layer 25 increases the connection strength between the two adjacent multi-functional integrated decorative panels and seals the gap between them, making the connection between the two multi-functional integrated decorative panels more stable and waterproof.

[0043] The upper decorative layer 1 is made of reinforced cement mixed with colorant, specifically magnesium oxychloride cement or glass fiber reinforced cement. The side of the upper decorative layer 1 facing away from the insulation layer 2 can be customized with patterns or three-dimensional designs resembling standard bricks, simulated stone, or imitation ceramic tiles, according to customer requirements, making the appearance of this multi-functional integrated decorative panel more aesthetically pleasing and realistic. The particularly realistic three-dimensional patterns fully replicate the lifelike effects of existing building decoration materials such as bricks, marble, and ceramic tiles used in exterior wall and partition wall decoration processes. Furthermore, the color of the decorative layer pattern in this invention is not applied later, but rather formed by mixing colorant pigments with reinforced cement, thus exhibiting strong weather resistance and being less prone to fading.

[0044] This multifunctional integrated molded decorative panel is mainly used for exterior wall construction. When installing the panel, workers can directly apply concrete or other adhesives to the base wall surface and the bottom surface of the insulation layer 2. Then, the bottom surface of the insulation layer 2 is directly adhered to the wall surface to complete the installation. Alternatively, it can be fixed to the base wall using adhesives or anchoring. When the base wall is a lightweight cement grouting wall, the decorative panel can be used without formwork removal, allowing the lightweight cement grouting wall and the decorative panel to be directly bonded together without the need for adhesives or anchoring.

[0047] The thickness of the upper decorative layer 1 and the lower decorative layer 3 of the multifunctional integrally-formed decorative plate is 1 cm, and the thickness of the thermal insulation layer is 50 mm-120 mm. The staff can select the thermal insulation layer with a thickness of 50 mm, 75 mm, 90 mm, 100 mm or 120 mm according to the different paving positions.

[0048] The material of the upper decorative layer 1 and the lower decorative layer 3 is reinforced cement mixed with color paste, which can be specifically magnesite cement or glass fiber reinforced cement.
