Problems solved by technology

Existing PE film protective tape will produce a lot of "ghosts" (a substance remaining on the screen panel of the mobile phone, invisible to the naked eye and needs to be seen with a bright flashlight) on the screen panel of the touch screen mobile phone. Contamination of the mobile phone screen panel when it is not assembled to the mobile phone
It seriously affects the appearance of the mobile phone screen, causing manufacturers to re-clean it

Embodiment Construction

[0015] A solvent-type acrylic pressure-sensitive adhesive and a preparation method thereof, characterized in that the formula is composed of the following components in weight percentages: 1-3% of acrylic acid, 8-0.5% of hydroxyethyl acrylate, 8% of hydroxypropyl acrylate ~0.5%, hydroxybutyl acrylate 8~0.5%, isooctyl acrylate 24~71%, butyl acrylate 20~71%, solvent 20~70%, initiator 1‰~4‰. The solvent is a mixed system of ethyl acetate, acetone, and toluene, and the ethyl acetate, acetone, and toluene are mixed in a ratio of 9:0.5:0.5. The initiator uses azobisisobutyronitrile and peroxydicarbonate bis(4-tert-butylcyclohexyl).

[0016] Among them, the production method is: after mixing isooctyl acrylate, butyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, hydroxybutyl acrylate, acrylic acid, ethyl acetate, acetone, and toluene uniformly in proportion, divide them into Divide into two parts equally; add one thousandth of azobisisobutyronitrile to the first part and h...

Abstract

The invention discloses a solvent type acrylic pressure sensitive adhesive and a preparation method thereof. The solvent type acrylic pressure sensitive adhesive of the formula is prepared from, by weight, 1-3% of acrylic acid, 0.5-8% of hydroxyethyl acrylate, 0.5-8% of hydroxy-propyl acrylate, 0.5-8% of hydroxy-butyl acrylate, 24-71% of iso-cctyl acrylate, 20-71% of butyl acrylate, 20-70% of solvents and 1-4%o of initiators. An ethyl acetate, acetone and toluene mixed system is adopted for the solvent, and ethyl acetate, acetone and toluene are mixed according to the proportion of 9:0.5:0.5. The initiators are prepared from azodiisobutyronitrile and bis(4-tert-butylcyclohexyl)peroxydicarbonate. The acrylic adhesive for PE protective films is provided, and the protective films are mainly used for protecting screens in the mobile phone producing process. The adhesive has good adhesive force on base materials and meanwhile well solves the 'ghost' problem.

Description

technical field [0001] The invention belongs to the adhesive in the field of chemical industry, and relates to a solvent-type acrylic adhesive for polyethylene (PE) film. Background technique [0002] Surface protection tape is a kind of tape mainly used to protect the surface of materials, mainly to prevent the surface of the protected product from being scratched, polluted and corroded during processing, transportation, storage and use. [0003] There are many types of surface protection film tapes, including polyethylene (PE), polyvinyl chloride (PVC), polyester (PET), polypropylene (PP) and paper base according to the base material. In addition, plastic films such as nylon, polycarbonate, polyimide and other polyolefins can be used to prepare surface protection tapes. [0004] Surface protection tape is widely used because of its convenient use and good protection effect, such as hardware industry, optoelectronic industry, plastic industry, printing industry, wire and c...
