Description

Technical Field

[0001] This utility model relates to the field of thermal insulation materials technology, specifically to a fiber-reinforced rubber and plastic part. Background Technology

[0002] Insulation materials play a vital role in many fields such as construction, cold chain logistics, and industrial pipeline insulation. Among them, insulation boards are a commonly used form of insulation and the demand is increasing. Rubber and plastic materials have been widely used in insulation board manufacturing due to their good flexibility, ease of processing and molding, and the initial insulation performance brought by their closed-cell structure. However, traditional rubber and plastic insulation boards have revealed many problems that need to be solved in practical applications.

[0003] The poor mechanical properties of traditional rubber and plastic insulation boards are one of the key factors restricting their widespread application. In building exterior wall insulation systems, insulation boards need to withstand their own weight, wind loads, and stresses caused by temperature changes over long periods. Due to the insufficient strength and rigidity of rubber and plastic materials, traditional rubber and plastic insulation boards are prone to deformation, cracking, and even detachment. For example, in some high-rise buildings, after a period of use, some traditional rubber and plastic insulation boards have undergone significant bending deformation under wind force, leading to adhesion failure with the wall. This not only affects the insulation effect but also poses a serious threat to the building's safety and appearance. In the cold chain logistics field, insulation boards are easily subjected to external pressure and collisions during handling and stacking. Traditional rubber and plastic insulation boards often cannot withstand these forces, resulting in damage and affecting the storage quality of cold chain goods.

[0004] Rubber and plastic insulation boards used outdoors, such as building exterior wall insulation boards, are exposed to sunlight for a long time. Ultraviolet rays will cause changes in the molecular structure of rubber and plastic materials, leading to material aging, discoloration, and a decline in physical properties. Traditional rubber and plastic insulation boards usually lack effective UV protection measures. After a period of UV exposure, the surface will become rough, yellow, or even powdery, which will seriously shorten the service life of the insulation board.

[0005] During the installation, use, and maintenance of insulation boards, friction with surrounding objects is inevitable. For example, when installing insulation boards on a construction site, workers may scratch the surface of the insulation boards during handling and adjustment; in cold chain warehouses, goods may also rub against the insulation boards during stacking and handling; traditional rubber and plastic insulation boards have insufficient surface wear resistance, making them prone to scratches and wear, which not only affects the appearance but may also damage the integrity of the insulation layer and reduce the insulation effect.

[0006] In conclusion, developing a fiber-reinforced rubber and plastic insulation board with good mechanical properties, multiple functional characteristics, and stable and reliable structure is of great practical significance and can better meet the market demand for high-performance insulation materials. Summary of the Invention

A third adhesive layer, a basalt fiber mesh layer, a fourth adhesive layer, and an aluminum foil layer are sequentially stacked on the lower surface of the base material layer. The glass fiber reinforcement layer adopts a woven structure with interlaced warp and weft threads. The surface functional layer includes a polyethylene transition layer, a UV protection layer, and a wear-resistant layer from the inside out. The basalt fiber mesh layer adopts a reinforced mesh structure with mutually perpendicular and interlaced horizontal and vertical strips forming a mesh size.

[0012] The surface of the basalt fiber mesh layer is coated with a flame-retardant coating.

[0013] The UV protection layer is made of nano-titanium dioxide material with a thickness of 0.1mm; the wear-resistant layer is made of water-based polyurethane resin material with a thickness of 0.2mm.

[0014] The substrate layer has several through holes with a diameter of 2-3 mm. The holes are filled with glass fiber sound insulation cotton with a filling density of 80-100 kg / m³.

[0015] The thickness of the first, second, third, and fourth adhesive layers is 0.05-0.1 mm, and they are made of acrylic adhesive.

[0016] The thickness of the aluminum foil layer is 0.5-0.9mm.

[0031] The polyethylene transition layer 51 is located in the innermost layer of the surface functional layer 5 and is connected to the second adhesive layer 4. It plays a transition and buffering role. The thickness of the polyethylene transition layer 51 is 0.08-0.12mm. Its function is to buffer the stress between the substrate layer and the UV protection layer and prevent interlayer peeling.

[0032] The UV protection layer 52 is made of nano-titanium dioxide material with a thickness of 0.1mm, which can effectively block ultraviolet rays and prevent rubber and plastic parts from aging due to ultraviolet radiation.

[0033] The wear-resistant layer 53 is made of water-based polyurethane resin material with a thickness of 0.2mm. It has high wear resistance and can protect the surface of rubber and plastic parts from wear.

[0034] The basalt fiber mesh layer 7 is formed by horizontal and vertical strips arranged perpendicularly to each other to form a reinforced mesh structure with a mesh size of 5mm×5mm and a thickness of 0.2-0.4mm; its surface is coated with a flame-retardant coating, which can improve the flame-retardant performance of rubber and plastic parts.

[0035] The aluminum foil layer 9 is 0.5-0.9mm thick and has an anti-slip textured surface, which increases friction when in contact with other objects and provides an anti-slip effect.

[0036] The manufacturing process of this fiber-reinforced rubber and plastic part is as follows: 1. Preparation of substrate layer 1: Rubber and plastic materials are made into substrates of the required shape and size through injection molding or extrusion. Several through holes with a diameter of 2-3mm are drilled inside the substrate according to the design requirements. Then, glass fiber sound insulation cotton is filled into the through holes, and the filling density is controlled to be 80-100kg / m³.

[0037] 2. Preparation of glass fiber reinforcement layer 3: The glass fiber is woven into a reinforcement layer with a required thickness of 0.15-0.3mm by using a weaving process of interlacing warp and weft threads.

[0038] 3. Preparation of surface functional layer 5: First, a polyethylene transition layer 51 is prepared; then, nano-titanium dioxide material is coated on the polyethylene transition layer 51 to form a UV-resistant layer 52 with a thickness of 0.1 mm; finally, water-based polyurethane resin material is coated on the UV-resistant layer 52 to form a wear-resistant layer 53 with a thickness of 0.2 mm.

[0039] 4. Preparation of basalt fiber mesh layer 7: Basalt fibers are woven into horizontal and vertical strips in a mutually perpendicular interlacing manner to form a reinforced mesh structure with a mesh size of 5mm×5mm and a thickness controlled at 0.2-0.4mm. Then, a flame-retardant coating is applied to the surface of the mesh.

[0040] 5. Preparation of aluminum foil layer 9: The aluminum foil material is processed into an aluminum foil layer with a required thickness of 0.5-0.9mm, and an anti-slip embossed structure is formed on its surface through processes such as embossing.

[0041] 6. Overall Assembly: The prepared layers are bonded together sequentially using adhesive layers. Acrylic adhesive is evenly applied to the surface of the corresponding layers, with the coating thickness controlled at 0.05-0.1 mm, forming the first adhesive layer 2, the second adhesive layer 4, the third adhesive layer 6, and the fourth adhesive layer 8. Specifically, the first adhesive layer 2, the glass fiber reinforcement layer 3, the second adhesive layer 4, and the surface functional layer 5 are bonded sequentially to the upper surface of the substrate layer 1; the third adhesive layer 6, the basalt fiber mesh layer 7, the fourth adhesive layer 8, and the aluminum foil layer 9 are bonded sequentially to the lower surface of the substrate layer 1, ultimately producing a fiber-reinforced rubber and plastic part.

[0042] The strength enhancement principle of this fiber-reinforced rubber and plastic part is as follows: the glass fiber reinforcement layer 3 adopts a woven structure with interlaced warp and weft threads, which can withstand tensile and compressive forces in all directions, effectively enhancing the overall strength of the rubber and plastic part; the basalt fiber mesh layer 7 forms a reinforcing mesh structure through mutually perpendicular horizontal and vertical strips, further improving the tensile and tear resistance of the rubber and plastic part.

[0043] The functional principle of this fiber-reinforced rubber and plastic part is as follows: Sound insulation principle: The through holes inside the substrate layer 1 are filled with glass fiber sound insulation cotton. When sound travels to the rubber and plastic parts, the sound insulation cotton can absorb and reflect sound waves, reduce the transmission of sound, and thus achieve the sound insulation effect. UV protection principle: The UV protection layer 52 in the surface functional layer 5 is made of nano titanium dioxide material. Nano titanium dioxide can absorb and scatter ultraviolet rays, prevent ultraviolet rays from penetrating the rubber and plastic parts, and protect the internal materials from ultraviolet damage. Wear resistance principle: The wear-resistant layer 53 is made of water-based polyurethane resin material, which has high hardness and wear resistance. When the surface of the rubber and plastic parts is subjected to friction, the wear-resistant layer 53 can resist wear and extend the service life of the rubber and plastic parts. Flame retardant principle: The surface of the basalt fiber mesh layer 7 is coated with a flame retardant coating. When it encounters a fire source, the flame retardant coating can prevent the spread of flames and improve the flame retardant performance of rubber and plastic parts. Anti-slip principle: The surface of aluminum foil layer 9 has an anti-slip textured structure, which increases the friction when in contact with other objects, thus playing an anti-slip role.

[0044] This fiber-reinforced rubber and plastic part solves the problems of easy deformation, cracking, and detachment of traditional rubber and plastic parts, and better meets the market's demand for high-performance materials.
