Abstract

The invention discloses an adhesive for a high-finish board protecting film. The adhesive is prepared from raw materials in parts by weight as follows: a component A including 230-250 parts of soft water, 1-3 parts of baking soda, 4-5 parts of an initiator, 20-30 parts of an emulsifier, 380-420 parts of ethylhexyl acrylate, 180-220 parts of butyl acrylate, 150-170 parts of methacrylic acid, 10-15parts of hydroxyethyl acrylate, 25-35 parts of acrylic acid and 1-3 parts of a coupling agent; a component B including 800-900 parts of soft water and 0.1-0.5 parts of ammonium persulfate; a componentC including 25-35 parts of soft water and 1-2 parts of tert-butyl hydroperoxide; a component D including 25-35 parts of soft water and 1-2 parts of rongalite, a component E including 0.1-0.3 parts ofa defoamer and a component F including 12-18 parts of ammonia water with the concentration of 20%. The adhesive is high in drying speed and requires lower temperature for drying, and the well-made film has good transparency, and is not prone to tackification or debonding.

Description

technical field [0001] The invention relates to a glue, in particular to an adhesive for a plate protective film with high smoothness and a preparation method thereof, belonging to the field of glue. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, high-gloss boards are more and more widely used in various occasions. The surface of this type of board is easily scratched during transportation and use. In order to protect the surface of the board, generally Its outer surface is pasted with a layer of anti-scratch film, which is called the plate protection film. [0003] In the production and processing of high-gloss board protective film, glue (adhesive) needs to be coated on the substrate film. For the board protective film with higher smoothness, the existing glue (adhesive) has a slow drying speed, and the temperature required for drying is relatively high, and the prepared film has poor transpar...
