- the film produced by the extrusion or calendering method has the advantage of excellent productivity and low price.
- An object of this invention is to provide the manufacturing method of an acrylic film, and an acrylic film.
- the present invention as a means for solving the above problems, a first step of forming an acrylic resin syrup; And it provides a method for producing an acrylic film comprising a second step of curing by irradiating ultraviolet light to the acrylic resin syrup formed in the first step.
- the present invention provides another acrylic film produced according to the method of the present invention as another means for solving the above problems.
- the film according to the present invention can be applied to various industrial sheets such as protective films of various semiconductor processes, adhesives or adhesives for optical processes, adhesives or adhesives for electronic components, or laminate products having a multi-layered structure to exert excellent effects. have.
- the present invention the first step of forming an acrylic resin syrup; And It relates to a method for producing an acrylic film comprising a second step of curing by irradiating ultraviolet light to the acrylic resin syrup formed in the first step.
- composition of the acrylic resin syrup used in the first step of the present invention is not particularly limited.
- acrylic polymer acrylic polymer
- Acrylic resin syrup may be used as the reactive monomer and the photoinitiator.
- the composition of the acrylic polymer contained in the acrylic resin syrup is not particularly limited.
- an acrylic polymer having a glass transition temperature of 30 ° C. or more can be used. If the glass transition temperature of the acrylic polymer is less than 30 ° C., the glass transition temperature of the produced film may be too low, or the tack characteristics may be too high, which may limit the use of the film.
- acrylic polymers include, for example, (meth) acrylic acid alkyl esters; (Meth) acrylic acid aryl esters; (Meth) acrylic acid alkoxyalkyl esters; Carboxyl group-containing compounds; Hydroxy group-containing compound; Nitrogen-containing compounds; Glycidyl group-containing compounds; It may be a polymer of a monomer mixture comprising at least one selected from the group consisting of styrenic compounds and carboxylic acid vinyl esters.

Can be selected.
- the method of manufacturing the acrylic polymer containing each said component is not specifically limited.
- it may be prepared by a general polymerization method such as solution polymerization, photopolymerization, bulk polymerization, suspension polymerization or emulsion polymerization.
- a general polymerization method such as solution polymerization, photopolymerization, bulk polymerization, suspension polymerization or emulsion polymerization.
- it is especially preferable to use the solution polymerization method.
- the solution polymerization is preferably carried out at a polymerization temperature of 50 °C to 140 °C by mixing the initiator in a state where each monomer is uniformly mixed.
