Abstract
The invention discloses tear tape paper for electronic industry and a preparation of the tear tape paper. The tear tape paper is obtained by painting a coating on the surface of a paper base material, and then drying the coated paper base material, wherein the coating mainly comprises natural latex, carboxylic butadiene-styrene latex, and an acrylate emulsion. The preparation method disclosed by the invention is simple; the coating uses water as a dispersion medium, is free from the volatilization of any organic solvent, environment-friendly and pollution-free; the coating is thin, and therefore, a product can be completely recycled after application; and the prepared tear tape paper is wide in adaptability, good in tension force, and low in cost.
Description
Technical field
The present invention relates to the speciality paper field, particularly relate to a kind of manufacture method of the tearing tape paper for electronic devices and components.
Background technology
The used in electronic industry tearing tape paper that the present invention relates to is a kind of speciality paper that uses in the electronic devices and components manufacture process, its main and pressure sensitive adhesive tape, Hot melt adhesive tape or with self common use of fitting, be used for electronic devices and components and arrange fixing or resistor, capacitor bearing band formula are produced, or braid formula packing.Electronic devices and components of a great variety, also require tearing tape paper to have adaptability widely, can be applied to different occasions, with various glue-lines energy good fit, this has just proposed the higher adaptability requirement to the dope layer of tearing tape paper, requiring has certain compatibility between the various glue-line components of its dope layer and applying, thereby satisfies the extensive adaptive requirement of tearing tape paper.In addition, in some occasion, using tearing tape paper and not using the purpose of pressure sensitive adhesive tape series products is in order to reduce cost, because tearing tape paper from cost, is to be lower than general pressure sensitive adhesive tape; And these materials are the process material in the electronic devices and components manufacture process, will be dropped after finishing its mission, therefore using tearing tape paper also is trend of the times aspect environmental protection, because the material of main part of tearing tape paper is degradable paper material, has only very small amount of coating, with respect to the papery pressure sensitive adhesive, the composition of its petrochemicals is wanted much less, complete recyclable recycling.
Summary of the invention
The invention provides a kind of used in electronic industry tearing tape paper and preparation method thereof, the tearing tape paper that obtains and other base material (various pressure sensitive adhesive tapes, Hot melt adhesive tape or self) all can good fit, and applicability is wide, and pulling force is good, and cost is low.
Used in electronic industry tearing tape paper provided by the invention is made up of paper substrates and dope layer, and coating is coated on the surface of paper substrates, after the drying namely.Wherein formulation for coating material is made up of the raw material of following quality percentage composition:
Heveatex (solid content 60%) 10%～50%, carboxylic styrene butadiene latex (solid content 50%) 2%～30%, acrylic acid ester emulsion (solid content 45%) 2%～30%, age resistor 0.01%～4%, coating additive 0.001%～2%, surplus is water.
Described Heveatex is unmodified Heveatex; Described carboxy styrene-butadiene rubber Ruzhong styrene and butadiene mass ratio are (20～50): (80～50); Described acrylic acid ester emulsion is monomer mixture emulsion copolymerization gained, and monomer mixture is made up of 1～10 parts by weight of acrylic acid, 0～10 weight portion vinyl acetate, 0～20 parts by weight of methylmethacrylate, 20～80 parts by weight of acrylic acid butyl esters, 0～10 parts by weight of acrylic acid ethyl ester, 0～10 weight portion n-methylolacrylamide; Described age resistor is N, N-dibutylamino two bamic acid zinc, 2, one or more in the 6-toluene di-tert-butyl phenol.
Paper substrates of the present invention adopts natural kraft, white kraft, powerful brown paper, ribbed kraft paper etc. that paper or the cardboard of certain intensity are arranged.The thickness of paper substrates or quantitatively without limits in order to guarantee certain TENSILE STRENGTH, adopts 40～200g/m usually
2Paper wood, preferred 60～80g/m
2
Used in electronic industry tearing tape paper of the present invention is after coating is mixed, and the mode that adopts the papermaking single face to be coated with is coated the surface of paper substrates, 60～120 ℃ of following oven dry namely.Described coating solid content is 35%～60%, and coating weight is 4～15g/m
2, from using and cost consideration preferred 6～10g/m
2, the coating metering method is a kind of in scraper, air knife, scraper or the roll-type.
The present invention is special because of coating, adapts to extensively, and because coating is thin, cost is low, and environmental protection and energy saving.Coating material is decentralized medium with water, so no any organic solvent volatilization in the coating procedure, healthy harmless to the operator, and coating is thin, can recycle fully after the product use.
