TECHNICAL FIELD

[0001] The utility model relates to the related technical field of composite board especially, relates to a high performance rock wool composite board. BACKGROUND

[0002] Rock wool composite board is made of basalt and other natural minerals as the main raw material, through high temperature melting, fiberization treatment, and then adding appropriate amount of binder solidification processing. It has good heat preservation, fireproof, antibacterial and other properties, and is widely used in building, industrial equipment, ship and other fields, as heat insulation, sound insulation material.

[0003] But the existing rock wool composite board has the defects of loose, low strength, porous water absorption, which limits the use of rock wool composite board. Loose and low-strength rock wool composite board often has poor bearing capacity and is difficult to withstand large load or external force impact. This limits the use of the board in some application scenarios that require high strength and stability. Low-strength boards are prone to damage or deformation when subjected to external forces, which not only affects the appearance, but also may pose a threat to safety. Porous water-absorbing boards are prone to absorb moisture and pollutants in the environment, resulting in a decrease in board performance. At the same time, the water-absorbed board may also become a breeding ground for bacteria and mold, causing adverse effects on the environment and human health. Therefore, we propose a high-performance rock wool composite board. UTILITY MODEL CONTENTS

[0027] Embodiment one

[0028] As shown in Figure 1 and Figure 2 The present application is a high-performance rock wool composite board, comprising a thermal insulation material 1, a reinforcing fiber mesh cloth 2 and a bonding coating layer 4.

[0029] The reinforcing fiber mesh cloth 2 is arranged on the upper and lower surfaces of the thermal insulation material 1, and the thermal insulation material 1 comprises a rock wool substrate. The thermal insulation material 1 and the reinforcing fiber mesh cloth 2 on the upper and lower surfaces are vertically stitched together by stitching lines 3, and then a bonding coating layer 4 is formed by uniformly applying a finishing adhesive coating material on at least one of the upper and lower reinforcing fiber mesh cloths 2, thereby forming a complete structure of the high-performance rock wool composite board.

[0030] The stitching lines 3 penetrate between the upper and lower reinforcing fiber mesh cloths 2, and the stitching lines 3 are uniformly arranged in multiple rows and / or multiple columns.

[0031] By arranging the reinforcing fiber mesh cloth on both surfaces of the thermal insulation material and vertically penetrating and stitching with the stitching lines, the thermal insulation material and the reinforcing fiber mesh cloth can be effectively fixed together, ensuring the integrity of the board, improving the vertical pull strength, surface strength and hardness, flatness and connection reliability of the composite board, and effectively solving the problem of segregation and stratification of the thermal insulation material and the reinforcing fiber mesh cloth.

[0032] In this embodiment, the high-performance rock wool composite board takes rock wool board as the core. Rock wool has extremely low thermal conductivity, which can greatly reduce heat transfer and improve the thermal insulation effect of buildings. Moreover, rock wool has extremely high fire resistance and is not easy to burn, and will not produce toxic smoke, providing reliable safety protection for buildings. The rock wool composite board has excellent air permeability and waterproofness, can maintain dryness in humid environments, and effectively prevents the growth of mold. The rock wool composite board has stable structure and is not easy to deform, can withstand certain external impact, and has certain corrosion resistance, can resist the erosion of acid, alkali and other chemicals, and prolong the service life.

[0033] The reinforcing fiber mesh cloth 2 can be of the same material or different materials, and the reinforcing fiber mesh cloth 2 is glass fiber or basalt fiber or alumina fiber. The reinforcing fiber mesh cloth 2 can improve the surface strength and flatness of the high-performance rock wool composite board. The reinforcing fiber mesh cloth 2 on the upper and lower surfaces is of the same material with the same density, or of the same material with different densities, or of different materials, and the reinforcing fiber mesh cloth 2 is preferably basalt fiber. The stitching lines 3 are uniformly arranged in multiple rows and / or multiple columns between the reinforcing fiber mesh cloths 2 on the upper and lower surfaces.

[0034] In addition, the stitching lines 3 can be selected from one or more of carbon fiber stitching lines, glass fiber stitching lines, basalt fiber stitching lines, alumina fiber stitching lines, quartz fiber stitching lines, aramid stitching lines, steel wire, blended fiber stitching lines or regenerated fibers (such as regenerated polyester fibers). Preferably, in some application occasions, reinforcing fiber mesh cloth woven from natural fibers (such as bamboo fiber and hemp fiber) can also be used to reduce dependence on primary resources and reduce environmental pollution.

[0035] The outer sides of the reinforcing fiber mesh cloths 2 on the upper and lower surfaces are coated with adhesive coating layers 4, and the adhesive coating layers 4 are coated on the outer surfaces of the reinforcing fiber mesh cloths 2. The adhesive coating layers 4 provide secondary waterproof and moisture-proof function for the porous moisture-absorbing thermal insulation material 1, and completely seal the external fibers and dust, which eliminates dust pollution in construction site application and plays a positive role in haze control and emission reduction and worker health.

[0036] The application uses three-dimensional covering reinforcement technology to sequentially lay the reinforcing fiber mesh cloth 2 on both sides of the rock wool base thermal insulation material 1 and vertically sew the reinforcing fiber mesh cloth 2 through the stitching lines 3, and the rock wool base thermal insulation material 1, the reinforcing fiber mesh cloth 2 and the stitching lines 3 are solidified into an integral structure by coating the adhesive coating layer 4.

[0037] Vertical stitching solves the problem of separation and delamination between thermal insulation material 1 and reinforcing fiber mesh 2; the two-sided reinforcing fiber mesh 2 and the covering adhesive layer 4 provide overall reinforcement to the loose and low-strength surface of thermal insulation material 1, while improving material homogeneity and high compatibility, and enhancing the connection between thermal insulation material 1 and reinforcing fiber mesh 2.

[0038] This expands the application scope and fields of fiberboard beyond its previous single filling method.

[0039] Example 2:

[0040] The difference between Example 2 and Example 1 is that: Figure 3 As shown, a high-performance rock wool composite board further includes: firstly pre-treating the rock wool substrate, specifically, pre-immersing the rock wool substrate in an aerosol to form a curing layer on its upper and lower surfaces, and then applying a penetrating interface agent to the surface of the curing layer to form an interface modification layer 5.

[0041] Then, an adhesive plastering material is applied to the surface of one of the interface modification layers 5 to form an adhesive plastering layer 4. The other interface modification layer 5, which is not coated with adhesive plastering material, is molded together with the composite decorative panel in one step to form an integrated heat-insulating and decorative panel. The decorative panel includes any one of the following: calcium silicate board, aluminum metal decorative panel, Class A non-combustible aluminum composite panel, ceramic thin plate, and soft ceramic sheet.

[0042] Alternatively, an adhesive plastering coating material can be applied to the surfaces of both the upper and lower interface modified layers 5 to form an adhesive coating layer 4. Then, a fireproof and crack-resistant layer can be applied to the adhesive coating layer 4, followed by a decorative mortar or imitation stone coating to create an integrated heat-insulating and decorative thin plaster panel.

[0043] By pretreating the rock wool substrate by first immersing and curing it with an aerogel solution, the thermal conductivity of the rock wool board can be reduced from 0.04 W / (m·K) to 0.035 W / (m·K). This also seals the surface pores of the rock wool, reducing airflow within them. The biggest advantage of this innovation is that, while meeting mandatory energy-saving requirements, it requires a thinner and lower density than other untreated rock wool, achieving lighter, thinner, and more efficient lightweight high-strength performance. 2. Laying reinforcing fiber mesh: In practical applications, an additional penetrating interface agent can be added to the cured layer on the surface of the rock wool board after immersion, or it can be omitted, depending on the material and characteristics of the immersion adhesive, before bonding the covering material.

[0044] The high-performance rock wool composite board is a multi-layer composite structure.

[0045] The functional layer 7 is at least one of a heat insulation coating layer, a sound insulation coating layer, a waterproof protection layer, an air isolation film and a reinforced protection layer.

[0046] The sound insulation coating layer is a sheet-shaped sound insulation cotton or a multi-layer composite structure, and the multi-layer composite structure comprises a microporous sound absorption material, a damping material and a high-density sound insulation layer to form a multi-layer sound insulation system.

[0047] The above description is only an exemplary embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the present application is included in the patent protection range of the present application.

[0048] In addition, if "and / or" or "and / or" appears throughout the text, it means that the three parallel solutions include "A and / or B", including A solution, or B solution, or A and B solution. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled personnel in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor is it within the protection range required by the present application.
