Embodiment 1

[0029] 10.5g of butyl acrylate, 15.2g of isooctyl acrylate, 1.2g of methyl acrylate, 1.3g of hydroxyethyl acrylate, 1.8g of heptadecyl methacrylate, 0.08g of benzoyl peroxide, and nano-silica 0.05 g, 5 g of toluene, and 30 g of ethyl acetate were uniformly mixed to obtain a reaction mixture.

[0030] Add 10g of the reaction mixture into the reactor, start heating, initiate the polymerization reaction at 80-95°C, start adding the remaining reaction mixture dropwise, control the reaction temperature at 80-95°C, and complete the dropwise addition within 2-5 hours. After the dropwise addition, keep the temperature at 75-85°C for 2-5h, lower the temperature to below 50°C, add 35g of ethyl acetate, and stir for 0.5-1h to obtain polyacrylate resin.

[0031] Add 30g ethyl acetate to the above polyacrylate resin, stir for 10~20min, add crosslinking agent L-752.5g, catalyst stannous oleate 0.002g, inhibitor acetylacetone 0.02g, viscosity reducer caprylic acid glyceride 0.1 g, and stir ...

Abstract

The invention discloses a preparation method of an ultralight strippable self-exhausting acrylate pressure-sensitive coating material and relates to the technical field of surface protection of glass, plastic, metal and the like. The preparation method sequentially comprises the following three steps of: preparing polyacrylate resin, preparing polyacrylate pressure-sensitive adhesive coating liquid, and preparing the ultralight strippable self-exhausting acrylate pressure-sensitive coating material. The obtained ultralight strippable self-exhausting acrylate pressure-sensitive coating material has ultralow viscosity and good exhaust performance and can be widely applied to protection of all kinds of smooth surfaces.

Description

technical field [0001] The invention relates to the technical field of surface protection of glass, plastic, metal, etc., and more specifically relates to a preparation method of an ultra-light stripping self-venting acrylate pressure-sensitive coating material. Background technique [0002] Glass (such as panels of mobile phones, PDAs, game consoles, etc.), metal sheets, plastic sheets and other finished or semi-finished products are prone to contact pollution during the process of manufacturing (such as LCD module process, optical film engineering protection), handling and use ( wear, scratches or dust contamination). It is usually covered with a protective film to protect it from damage and pollution. The protective film is mainly composed of a substrate such as PET, PE, CPP film, etc. and an adhesive coated on the substrate. [0003] For the protection of smooth surfaces such as plastic, hardware, metal, glass, etc., it is required to have ultra-low viscosity (1~3gf / 25...
