Embodiment 1~4

[0022] Embodiment 1~4: A kind of preparation method of weather-resistant advertising car sticker for outdoors, comprises base material layer 1, back glue layer 2 and release layer 3, one side of described base material layer 1 is coated on back glue layer 2. The side of the adhesive layer 2 facing away from the substrate layer 1 is provided with a release layer 3, and the adhesive layer is obtained by coating and drying the adhesive solution, which is prepared by the following steps:

[0023] S1. Mix 15~25 parts of methyl methacrylate, 15~25 parts of styrene, 15~20 parts of 2-ethylhexyl acrylate, 1~1.5 parts of trimethylpentanediol, and 1 part of dimethylaminopropionitrile ~5 parts and 50~75 parts of deionized water are mixed evenly, and the temperature is raised to 75~80°C, and 0.5~1.5 parts of azoisobutylcyanoformamide and 1~10 parts of acrylic acid are added dropwise to the mixed system, and the reaction is 3~ 4h;

[0024] S2. Cool to room temperature, add 1-5 parts of bis...

Embodiment 1

[0028] In Example 1, the addition ratio of methyl methacrylate to styrene is 1:1, the above-mentioned curing agent is selected from the curing agent S01-5, the above-mentioned emulsifier is selected from the ethoxylated C16-18-alcohol, and the above-mentioned substrate layer It is a PVC layer, the thickness of the above-mentioned substrate layer is 70 μm, and the thickness of the above-mentioned back glue layer is 15 μm.

Embodiment 2

[0029] In Example 2, the addition ratio of methyl methacrylate to styrene is 2:1, the above-mentioned curing agent is selected from the curing agent MH2844, the above-mentioned emulsifier is selected from glyceryl polyethylene oxide, and the above-mentioned substrate layer is a PVC layer. The thickness of the base material layer is 120 μm, and the thickness of the back adhesive layer is 25 μm.

Abstract

The invention discloses a method for preparing an outdoor weather-resistant advertising car sticker, which comprises a base material layer, an adhesive layer and a release layer, one side of the base material layer is coated on the adhesive layer, and the adhesive layer The side opposite to the substrate layer is provided with a release layer, and the adhesive layer is obtained by coating and drying the glue solution. The glue solution is obtained by the following steps: S1, adding 15 to 25 parts of methyl methacrylate, Mix 15~25 parts of styrene, 15~20 parts of 2-ethylhexyl acrylate, 1~1.5 parts of trimethylpentanediol, 1~5 parts of dimethylaminopropionitrile and 50~75 parts of deionized water , heat up to 75~80°C, add dropwise 0.5~1.5 parts of azoisobutylcyanoformamide and 1~10 parts of acrylic acid to the mixed system, and react for 3~4 hours; S2, cool to room temperature, add bis peroxide 2 , 1-5 parts of 4-dichlorobenzoyl, 1-1.5 parts of curing agent, 0.2-1 part of emulsifier and 0.1-1 part of hydroquinone, mix evenly to obtain glue; S3, evenly coat the glue On the substrate layer, dry to obtain the adhesive layer. The invention improves the waterproof performance, the adhesive force is basically unchanged, and the bonding is stable.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, and in particular relates to a preparation method of an outdoor weather-resistant advertising car sticker. Background technique [0002] Some existing advertising stickers, such as car stickers and water-based high-gloss PVC, all have PVC film, adhesive layer and release paper, wherein the release paper is composed of silicone oil layer, coating layer and bottom paper, and the silicone oil layer and advertising stickers The adhesive layer is connected, and the release paper is peeled off during use to expose the adhesive layer, and then the advertisement is pasted on the designated position. [0003] At present, the advertising stickers on the market and domestic production use oil-based pressure-sensitive adhesives. The glue has solvent residues, and the VOC emission does not meet the standard, so it can only be used in outdoor environments. Therefore, environmental-friendly water-based ...
