Description

Technical Field

[0001] This application relates to the field of polymer materials, and more specifically, to a sun-reflective fabric and its preparation method. Background Technology

[0002] Reflective sunshade fabric, as a key material, plays an irreplaceable role in numerous fields such as agricultural shading, building insulation, and outdoor protection. It primarily protects crops from excessive sunlight and UV damage by reflecting sunlight and reducing ultraviolet radiation, while also reducing heat accumulation inside buildings, creating a comfortable indoor environment. With societal progress and rising demands for quality of life, the application of reflective sunshade fabric is becoming increasingly widespread, and its market demand continues to grow. It not only affects the stability and yield of agricultural production but also plays a vital role in building energy conservation and the safety of outdoor personnel, providing strong protection for people's production and daily life.

[0003] For a long time, most sunscreen reflective fabrics on the market were made of polypropylene (PP). PP's lightweight nature makes it easy to transport and install; its resistance to chemical corrosion allows it to maintain stable performance in various complex environments, making it the mainstream choice for manufacturing sunscreen reflective fabrics. To align with the trend of green and low-carbon development and reduce reliance on virgin PP, the market has begun to promote the use of recycled PP materials in the production of sunscreen reflective fabrics. Furthermore, the industry typically uses fillers (such as calcium carbonate and talc) and compatibilizers to blend and modify recycled PP materials to improve their mechanical properties and weather resistance, aiming to enhance the material's practicality while ensuring environmental protection.

[0004] Existing technologies have significant shortcomings. PP materials rely on petroleum resources for synthesis, and large-scale production leads to increased petroleum consumption and high carbon emissions, which contradicts the current green and low-carbon development philosophy. While recycled PP materials offer some environmental advantages, they suffer from significant problems such as decreased mechanical properties, brittleness, and short service life, making them unsuitable for long-term practical applications. Even with blending modification using fillers and compatibilizers, mechanical strength can only be improved to a certain extent, failing to achieve a balance in material properties, reflectivity, and resistance to solar aging. This results in poor performance of the anti-sunlight reflective fabric in terms of reflectivity, UV resistance, and long-term weather resistance, failing to achieve the desired performance. Summary of the Invention

[0005] The purpose of this application is to overcome the above-mentioned technical problems and provide a sun-proof reflective fabric and its preparation method.

[0006] In a first aspect, this application provides a sun-reflective fabric composed of the following raw materials by weight percentage: 85-95% recycled PP masterbatch; 3-8% sun-reflective color masterbatch; 1-4% UV-resistant masterbatch; and 1-3% hydrostatic masterbatch. The sun-reflective color masterbatch is composed of pigments, electroplating silver resin, terpene resin, and rosin derivatives. The UV-resistant masterbatch is composed of multiple components including organosilicon cross-linked polyethylene, bismaleimide, boron-modified phenolic resin, and UV-resistant agents, and contains at least one UV-resistant agent. The hydrostatic masterbatch is cashew nut shell oil modified resin.

[0007] By adopting the above technical solutions, the use of PP recycled masterbatch reduces petroleum resource consumption and carbon emissions, thus achieving environmental benefits. In the anti-reflective color masterbatch, electroplated silver resin enhances the light reflection performance and sunlight blocking effect of the reflective fabric; terpene resin and rosin derivatives improve the masterbatch's dispersibility and adhesion, synergistically enhancing UV protection and reflectivity, and improving the processing stability and mechanical strength of the PP recycled masterbatch. In the anti-UV masterbatch, organosilicon cross-linked polyethylene improves the material's weather resistance and flexibility; bismaleimide enhances thermal stability and anti-aging properties; boron-modified phenolic resin improves flame retardancy and mechanical strength and assists in UV protection; the anti-UV agent directly absorbs or scatters ultraviolet rays to prevent material degradation, improving the anti-UV ability, physical properties, and durability of the anti-reflective fabric. The hydrostatic masterbatch reduces the material's water absorption rate, preventing performance degradation caused by moisture penetration, and synergistically improves the overall performance of the anti-reflective fabric with other masterbatches, ensuring a longer service life and practicality. The formulation system is adaptable to different qualities of recycled PP, ensuring product quality stability and suitability for large-scale industrial production.

[0008] Preferably, the anti-reflective color masterbatch is composed of colorant, electroplating silver resin, terpene resin, and rosin derivative in a weight ratio of 1:(1-3):(1-2):(0.5-1).

[0009] By adopting the above technical solution and limiting the weight ratio of each component in the anti-reflective color masterbatch, the synergistic effect of each component can be further precisely exerted, the enhancement effect of electroplating silver resin on reflective light performance can be improved, the effect of terpene resin and rosin derivative on the dispersibility and adhesion of the masterbatch and the synergistic enhancement of UV protection and reflective performance with electroplating silver resin can be enhanced, and the processing stability and mechanical strength of PP recycled masterbatch can be better improved.

[0010] Preferably, the rosin derivative is rosin-modified pentaerythritol ester and / or rosin-modified phenolic resin.

[0011] By adopting the above technical solution, using rosin-modified pentaerythritol ester and / or rosin-modified phenolic resin as rosin derivatives, combined with PP recycled masterbatch, a specific proportion of anti-reflective color masterbatch, anti-UV masterbatch, and hydrostatic pressure masterbatch, it can work synergistically with other raw materials to improve the UV protection capability, reflectivity, weather resistance, and mechanical properties of the anti-reflective fabric, ensuring a longer service life and practicality. At the same time, it makes the formulation system adaptable to PP recycled materials of different qualities, ensuring stable product quality and suitability for large-scale industrial production.

[0012] Preferably, the rosin derivative is composed of rosin-modified pentaerythritol ester and rosin-modified phenolic resin.

[0013] By adopting the above technical solutions, the use of recycled PP masterbatch can reduce dependence on virgin PP, thereby reducing petroleum resource consumption and carbon emissions. The electroplated silver resin in the anti-reflective masterbatch enhances the light reflection performance of the reflective fabric, while terpene resin and rosin derivatives (composed of rosin-modified pentaerythritol ester and rosin-modified phenolic resin) improve the dispersibility and adhesion of the masterbatch, synergistically enhancing UV protection and reflectivity with the electroplated silver resin, while also improving the processing stability and mechanical strength of the recycled PP masterbatch. The anti-UV masterbatch enhances the UV resistance and physical properties of the anti-reflective fabric. Performance and durability; hydrostatic masterbatch has excellent hydrophobic properties, which can reduce the water absorption rate of the material and synergistically improve the overall performance of the anti-sun reflective fabric with other masterbatches; the optimized compounding of PP recycled masterbatch with other masterbatches forms a synergistic effect system, which enables the anti-sun reflective fabric to have excellent UV protection, high reflectivity, weather resistance, low water absorption and mechanical properties, making it suitable for long-term outdoor use, ensuring a long service life and practicality, and the formulation system has good adaptability to PP recycled materials of different qualities, ensuring the quality stability of the final product, and is suitable for large-scale industrial production.

[0014] Preferably, the UV-resistant masterbatch is composed of organosilicon cross-linked polyethylene, bismaleimide, boron-modified phenolic resin, and UV-resistant agent.

[0015] By adopting the above technical solution, with the combination of PP recycled masterbatch, anti-reflective color masterbatch, and hydrostatic masterbatch, organosilicon cross-linked polyethylene improves the material's weather resistance and flexibility, reduces UV-induced embrittlement, bismaleimide enhances thermal stability and anti-aging properties, and extends service life, boron-modified phenolic resin improves flame retardancy and mechanical strength, and assists in UV protection, and UV-resistant agents directly absorb or scatter ultraviolet rays and prevent material degradation, significantly improving the UV resistance of the anti-reflective fabric, enhancing its physical properties and durability. This results in anti-reflective fabric with excellent UV protection, high reflectivity, weather resistance, low water absorption, and mechanical properties, suitable for long-term outdoor use, ensuring a long service life and practicality. Furthermore, the formulation system has good adaptability to PP recycled materials of different qualities, ensuring the quality stability of the final product, and is suitable for large-scale industrial production.

[0018] By adopting the above technical solutions, recycled PP materials have advantages such as low carbon emissions and environmental friendliness. β-crystalline polypropylene and fillers are uniformly mixed under the action of processing aids, giving the recycled PP masterbatch excellent comprehensive performance. Combined with the optimized compounding of anti-UV masterbatch, anti-reflective masterbatch, and hydrostatic masterbatch, a synergistic system is formed, enabling the anti-reflective fabric to possess excellent UV protection, high reflectivity, weather resistance, low water absorption, and mechanical properties, making it suitable for long-term outdoor use and ensuring a long service life and practicality. The formulation system has good adaptability to recycled PP materials of different qualities, effectively compensating for the impact of performance fluctuations in recycled materials, ensuring the quality stability of the final product, and making it suitable for large-scale industrial production.

[0019] Preferably, the relative molecular weight of the β-crystalline polypropylene is 100,000 to 200,000.

[0020] By adopting the above technical solution, PP recycled masterbatch is prepared using β-crystalline polypropylene with a relative molecular weight of 100,000-200,000. Combined with UV-resistant masterbatch, anti-reflective masterbatch, and hydrostatic masterbatch, a synergistic system is formed through optimized compounding. This system enables the anti-reflective fabric to possess excellent UV protection, high reflectivity, weather resistance, low water absorption, and mechanical properties, making it suitable for long-term outdoor use and ensuring a long service life and practicality. The formulation system has good adaptability to PP recycled materials of different qualities, can compensate for the impact of performance fluctuations in recycled materials, ensure the quality stability of the final product, and is suitable for large-scale industrial production.

[0021] Preferably, the processing aid is a combination of multiple components of hydrogenated vegetable oil, stearic acid, epoxidized soybean oil, and PE wax.

[0022] By adopting the above technical solutions, including PP recycled masterbatch, anti-reflective masterbatch, anti-UV masterbatch, and hydrostatic masterbatch, the use of virgin PP is reduced, thus lowering petroleum consumption and carbon emissions. Anti-reflective masterbatch enhances the light reflection and UV protection performance of reflective fabric, improving processing stability and mechanical strength. Anti-UV masterbatch improves UV resistance, physical properties, and durability. Hydrostatic masterbatch reduces water absorption and improves overall performance. The recycled PP material in the PP recycled masterbatch is environmentally friendly, and combined with other masterbatches to form a synergistic system, giving the reflective fabric multiple excellent properties. The formula is adaptable to different qualities of recycled PP material, ensuring stable product quality. The use of hydrogenated vegetable oil, stearic acid, epoxidized soybean oil, and PE wax as processing aids lowers processing temperature and promotes uniform mixing of raw materials.

[0023] Secondly, a method for preparing a sun-reflective fabric includes the following steps: weighing PP recycled masterbatch, sun-reflective color masterbatch, UV-resistant masterbatch, hydrostatic masterbatch, and processing aids according to weight percentages, mixing them evenly, and then melt-extruding to obtain a blended modified material; then melt-spinning, traction web laying, hot rolling molding, and winding and slitting the blended modified material to finally obtain the sun-reflective fabric.

The formula system has good adaptability to PP recycled materials of different qualities, can make up for the impact of performance fluctuations of recycled materials, ensure the stability of the final product quality, and is suitable for large-scale industrial production.
