Problems solved by technology

However, ordinary inkjet materials for indoor advertising are mostly made of photo paper, PP synthetic paper, PET and other materials. For applications such as curved surfaces, corners, and wrapping, quality problems such as air bubbles, creases, and warped edges are prone to occur, which affects the use. The effect; and the existing pressure-sensitive adhesive is easy to residue when removing advertising materials
Although outdoor car stickers can also be used as indoor inkjet materials, the inkjet ink used in car sticker products is solvent-based, which pollutes the work and use environment and is not suitable for indoor use.

Abstract

The invention belongs to the technical field of materials and especially relates to a removable vehicle paster and a preparation method and application thereof. The vehicle paster successively contains a water-based ink-jet ink-drawing layer, a primer layer, a PVC layer, a removable pressure sensitive adhesive layer and release paper. The water-based ink-jet ink-drawing layer is obtained by mixingand stirring 17-20% of water-based ink-drawing resin, 0.5-1% of a wetting agent and 79-82.5% of water. The primer layer is obtained by mixing and stirring 10-20% of water-based resin, 0.5-1% of a wetting agent and 89.5-79% of water. The removable pressure sensitive adhesive layer is composed of 20-30% of butyl acrylate, 1.5-3% of acrylic acid, 15-23% of methyl methacrylate, 0.5-2% of benzoyl peroxide, 18-30% of toluene, 27-40% of ethyl acetate, 1-5% of a curing agent, 1-5% of latex powder and 2-6% of nano-attapulgite. The vehicle paster can 100% remove residual gum, has good curved surface adhesion, and has no bubble, crease or edge warping phenomena.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a removable car sticker and a preparation method and application thereof. Background technique [0002] With the rapid development of the economy, inkjet printing materials for print advertisements have been widely used due to the characteristics of small batches, high speed, and high fidelity. However, ordinary inkjet materials for indoor advertising are mostly made of photo paper, PP synthetic paper, PET and other materials. For applications such as curved surfaces, corners, and wrapping, quality problems such as air bubbles, creases, and warped edges are prone to occur, which affects the use. effect; and the existing pressure-sensitive adhesives are prone to residual glue when removing advertising materials. Although outdoor car stickers can also be used as indoor inkjet materials, the inkjet ink used in car sticker products is solvent-based, which pollutes the ...
