AbstractThis study aims to deeply analyze the factors influencing the efficiency of self-adhesive back-glue spray paint masking tape, providing scientific and comprehensive guidance for tape selection and application in the spray painting industry. By analyzing the material composition (substrate and adhesive properties), high-temperature performance, application factors (width, thickness, back-glue uniformity), and environmental factors (humidity, dust), a combination of theoretical analysis and experimental testing was employed. The study found that different substrates and adhesives exhibit varied performances under high temperatures, application scenarios, and environmental conditions, with interrelated factors collectively affecting tape efficiency. This research contributes significantly to optimizing process flows, improving spray paint quality, and driving efficiency improvements in the industry.

Introduction1.1 BackgroundSelf-adhesive back-glue spray paint masking tape plays a crucial role in modern spray painting processes, widely used in automotive manufacturing, furniture spraying, and electronic device coatings. As a temporary protective material, it effectively shields non-spray areas from paint mist contamination, enhancing painting quality and efficiency [4]. Advancements in industrial technology demand higher precision, especially in multi-color, high-fidelity coatings, rendering traditional masking materials insufficient. Therefore, developing high-performance tapes has become imperative. PET substrates are prevalent in lower-temperature scenarios due to cost-effectiveness and mechanical properties, while PI materials dominate high-temperature environments with superior heat resistance. However, diverse application requirements prompt continuous exploration of novel materials and technologies [4].

1.2 Problem StatementDespite widespread use, existing research lacks a systematic analysis of multifactorial efficiency determinants. Most studies focus on singular performance parameters (e.g., heat resistance, adhesion, substrate strength), neglecting synergistic effects [4]. For instance, the matching of adhesive melting points and substrate deformation temperatures in high-temperature喷漆 environments remains understudied. Practical factors like tape width, thickness, and back-glue uniformity’s impact on usability and masking efficacy are also underexplored. Additionally, environmental mechanisms (humidity, dust, chemicals) require further clarification. This study aims to fill these gaps by holistically analyzing key efficiency影响因素, guiding industrial tape selection and application [4].

1.3 ObjectivesThe study targets: (1) Comparing PET and PI substrates’ temperature adaptability; (2) Assessing silicone vs. acrylic adhesive performance under heat; (3) Investigating width, thickness, and back-glue effects on application efficiency; (4) Analyzing environmental factor interactions; (5) Proposing optimization strategies. These findings will support tape development and application standardization in the喷漆 industry [4].

Literature Review2.1 Tape FundamentalsTapes consist of substrates (supporting mechanical strength and stability) and adhesives (providing bonding through van der Waals forces, hydrogen bonds, etc.). PET offers cost-effective mechanical strength, chemical resistance, and processability, ideal for <150°C scenarios. PI, with >300°C glass transition temperature, excels in high-temperature insulation and chemical robustness. Adhesives like silicone (high adhesion, heat resistance) and acrylic (cost-effective, broad compatibility) dominate the market. Substrate requirements include mechanical durability, dimensional stability, and thermal resistance, directly impacting tape performance [4].

2.2 Masking Tape Research ProgressRecent studies highlight material advancements: PET-silicone combinations excel in low-temperature喷漆 masking, while PI-acrylic systems suit high-temperature needs [4]. Process innovations (e.g., controlled coating thickness, surface treatments) enhance adhesion and contamination resistance. However, limitations persist: (1) Limited multifactorial analysis (e.g., combined high-temp/material interactions); (2) Inadequate studies on width/thickness effects in practical use; (3) Environmental factor-combination mechanisms remain unclear. This study bridges these gaps [4].

2.3 Research GapsCurrent literature lacks comprehensive analysis of: (1) Synergistic high-temperature performance of substrates and adhesives; (2) Practical application factors’ influence (width, thickness, back-glue distribution); (3) Environmental stressors’ compound effects. This study aims to systematically address these deficiencies, contributing both theoretically and practically to tape efficiency understanding [4].

Material Composition Impact3.1 Substrate Selection3.1.1 PET CharacteristicsPolyethylene terephthalate (PET) substrates are widely adopted for cost-effectiveness, mechanical robustness, and chemical resistance. Their high tensile strength and abrasion resistance prevent tape tearing during喷漆 manipulation. PET’s stability against common paint solvents ensures reliability. Economically, PET’s low production cost and easy processability support large-scale industrial use. However, its heat resistance limits applications to ≤150°C short-term exposures; prolonged high temperatures can cause softening or deformation, restricting its use in extreme environments [4].

3.1.2 PI CharacteristicsPolyimide (PI) substrates offer unparalleled high-temperature stability (sustaining >300°C) and electrical insulation, ideal for prolonged heat exposures. Their chemical inertness withstands complex industrial conditions. Despite high costs and processing challenges (complex synthesis, expensive raw materials), PI tapes dominate aerospace, automotive, and electronics喷漆 scenarios. However, PI’s poor flexibility may impair adherence to curved surfaces, potentially reducing masking efficiency compared to PET in certain geometries [4].

3.2 Adhesive Technologies3.2.1 Silicone AdhesiveSilicone adhesives dominate high-temperature masking tapes due to broad operating range (-50°C to 250°C), exceptional adhesion, and weather resistance. Their stability under UV, moisture, and thermal cycling ensures long-term performance. Though costly and requiring high-quality substrate pretreatment, silicone’s advantages outweigh drawbacks in critical applications. Its consistent adhesion retention during极端 temperatures makes it indispensable for industrial喷漆 masking [4].

3.2.2 Acrylic AdhesiveAcrylic adhesives balance cost and versatility, bonding well with diverse substrates. While offering lower heat resistance (typically ≤120°C) and inferior durability to silicone, their economic feasibility and wide compatibility drive adoption in lower-temperature喷漆 scenarios. Advancements in modified acrylics (e.g., crosslinking for enhanced heat tolerance) expand their application boundaries [4].
