Abstract

The invention discloses a high-elasticity silicon rubber heat transfer film and a preparation method thereof. The high-elasticity silicon rubber heat transfer film comprises a base substrate, whereina film removal layer is arranged on the base substrate, a scratch-resistant coating is arranged on the film removal layer, a rubber ink layer is arranged on the scratch-resistant coating, an adhesivelayer is arranged on the rubber ink layer, and a TPU hot melt adhesive film is adhered to the adhesive layer. According to the high-elasticity silicone rubber heat transfer film, by arranging the rubber ink layer in the preparation process, the heat transfer film has good stretchability and resilience, is resistant to water washing, is not prone to deform, and is high in softness. The TPU hot meltadhesive film is arranged so that the heat transfer film is good in elasticity and high in tear resistance, the used material is environment-friendly, odorless and non-toxic, the safety performance is good, and skin does not cause allergy after long-term contact with a silicone rubber surface. The arrangement of the scratch-resistant coating not only retains the texture of the TPU but also improves the scratch resistance and formability of resin.

Description

technical field [0001] The invention relates to the technical field of lettering film, in particular to a highly elastic silicon rubber lettering film and a preparation method thereof. Background technique [0002] Thermal transfer lettering film is a thermal transfer material with a high usage rate in the thermal transfer process. There are various types, and the thermal transfer lettering film is transferred to the ironing material. The ironing material is usually mainly on textiles such as clothes, shoes and hats, so as to increase their aesthetics and personalization to win the market. Most of the lettering films sold on the market are lettering films made of TPU material. The process is to first coat the back of the biaxially stretched polyester film with a 200-line anilox roller to coat the back coating liquid of the protective layer, and then further Oven drying; then apply a release agent on the front of the biaxially oriented polyester film with a comma scraper, an...
