Description

Technical Field

[0001] The present invention belongs to the technical field of protective films, and particularly relates to an adhesive material for a liquid crystal light guide plate protective film and a preparation method thereof. Background Art

[0002] The light guide plate applied to the liquid crystal screens of mobile phones, cameras and other digital electronic products is a product with high transparency and high clarity, and it has very high requirements for the production environment and surface quality. However, during the processing, handling and transportation of the light guide plate, it is inevitable to come into contact and friction with some parts of the equipment, or due to improper operation, resulting in scratches on its surface or adhesion of dust, oil stains, etc. Therefore, it is necessary to attach a protective film on the surface of the light guide plate, which consists of a substrate and an adhesive material, and needs to have certain characteristics such as inertness, adhesiveness, stability and practicability.

[0003] The existing liquid crystal light guide plate protective films have problems such as easy aging, residual glue, poor high-temperature resistance and flame retardancy, which greatly restrict their scope of use. Moreover, the adhesive for the liquid crystal light guide plate protective film is required to be colorless and transparent. Therefore, the existing technology adds various antioxidants to play their free radical scavenging role and antioxidant function, so as to overcome the defect that the adhesive layer after film formation changes color over time. However, traditional antioxidants are powdery at room temperature and are prone to precipitation even when dissolved in solvents. If the result of pursuing the antioxidant function is inevitable to increase its addition amount, there will be a defect that the antioxidant precipitates from the adhesive layer, resulting in a rapid decline in the adhesive performance of the adhesive material, and even losing adhesiveness, thereby affecting the use of the protective film. Summary of the Invention

[0004] To solve the deficiencies mentioned in the above background art, the purpose of the present invention is to provide an adhesive material for a liquid crystal light guide plate protective film and a preparation method thereof. By adding modified carbon nanotubes, the adhesive material is endowed with excellent high-temperature aging resistance, flame retardancy and damp-heat aging resistance, and has good adhesive performance.

[0029] The beneficial effects of the present invention:

[0030] The present invention utilizes a chemical reaction to graft two allyl isothiocyanate molecules into the structure of p-phenylenediamine to prepare Component 1. Then, Component 1 is subjected to a hydrosilylation reaction with 1,1,3,3-tetramethyldisiloxane to prepare Component 2. At the same time, Component 1 is subjected to a radical addition reaction with n-dodecyl mercaptan to prepare Component 3. Additionally, the present invention utilizes Component 3, vinyltriethoxysilane, and phenyltris(dimethylsilyl)silane to undergo a hydrosilylation reaction to prepare Component 4. Then, Component 2 and Component 4 are further subjected to a hydrosilylation reaction to prepare a modifier. This modifier contains both hydrophobic and flexible aliphatic long chains and a rigid benzene ring structure, possessing excellent mechanical properties and water resistance. At the same time, it contains multiple silicon-oxygen bonds, sulfur elements, and anti-aging -NH functional groups, endowing the bonding material with good high-temperature aging resistance, flame retardancy, and resistance to damp heat aging. The present invention utilizes the condensation reaction between the silicon hydroxyl groups in the modifier structure and the hydroxyl groups on the surface of carbon nanotubes, thereby binding the modifier to the surface of carbon nanotubes through strong chemical bonds, avoiding the problem of modifier migration and precipitation. At the same time, it enhances the lipophilicity of the carbon nanotube surface, promotes the relatively uniform dispersion of carbon nanotubes in the matrix, enables the full play of its comprehensive properties, and because the carbon nanotubes have a tubular structure, the functional components of the modifier can be slowly released, thereby achieving long-term high-temperature aging resistance, resistance to damp heat aging, and flame retardancy effects.

[0057] Performance Testing

[0058] The bonding materials prepared in Examples 3-5 and Comparative Examples 3-4 were hot-coated on a 25-μm PET film with a 40-μm wire bar, and after cutting into the required sample shapes, relevant performance tests were carried out:

[0060] (2) Weather resistance test: The samples were placed in an oven at 80 °C for 8 h for high-temperature aging test; the samples were immersed in deionized water for 8 h for water resistance test; the samples were placed in a constant temperature and humidity chamber at a temperature of 80 °C and a humidity of 90% RH for 100 h, taken out and naturally cooled to room temperature, and the surface was observed for residual glue after peeling for the resistance to damp heat aging performance test, and the data results are shown in Table 1.

[0063]

[0064]

[0065] As can be seen from the data in Table 1, the bonding materials prepared in Examples 3-5 of the present invention have excellent bonding properties, high temperature aging resistance, water resistance and flame retardancy, and there is no residual glue after peeling under high temperature and humid conditions, and the resistance to humid heat aging is good. Among them, in Comparative Example 3, the modifier grafted on the modified carbon nanotubes did not introduce Component III, and its measured peel strength and flame retardancy after aging treatment at 80°C and water immersion treatment were lower than those in Examples 3-5. The reason is that the anti-aging group, hydrophobic long chain and sulfur element in Component III were not introduced. In Comparative Example 4, the carbon nanotubes were not modified, and its measured peel strength and flame retardancy after aging treatment at 80°C and water immersion treatment were significantly lower than those in Examples 3-5, and there was a phenomenon of residual glue, indicating that the grafting of the modifier greatly improved the comprehensive performance of the bonding material.
