Abstract

The present invention discloses a waterproof and damp-proof raw paper dedicated for electronic paper tapes, and a preparation method thereof. The method is characterized in that untwining and fibrillation are carried out on pulp fibers, fibrillation and cutting are further carried out so as to enable a pulp beating degree to reach 45 degree SR to 48 degree SR and a fiber wet weight to be reduced to 5.5 g to 8.0 g; and a water-resistant damp-proof composition is added in each layer, 1.0%-2.5% of the water-resistant damp-proof composition is added in relative to 100 parts of the pulp fibers, the water-resistant damp-proof composition including 0.15+-0.015 % of a wet strength agent PAE, 0.50+-0.05 % of gum rosin or an alkyl ketene dimer (AKD), 0.10+-0.01 % of silicon and fluorine type polymers, and 0.15+-0.015 % of ammonium zirconium carbonate. According to the above method, defibrination treatment is utilized, and a water-resistant damp-proof functional chemical is added in the pulp and coated on the surface of paper, surface water absorption and an edge permeation index of the raw paper are lowered than like products on the market, and water-resistance and damp-proofness of the raw paper are the best.

Description

technical field

[0001] The invention belongs to the technical field of electronic information materials, and in particular relates to a special base paper for waterproof and moisture-proof electronic paper tape used in the packaging of chip electronic components in the technical field of microelectronics and a preparation method thereof. Background technique

[0002] With the miniaturization of electrical appliances, the miniaturization requirements for electronic components are getting higher and higher. When the size is large, it is acceptable to use plastic carrier tape, but when the size is smaller, the production of plastic carrier tape is very difficult. Dimensional accuracy is difficult to guarantee, especially it is difficult to eliminate the chamfer around when drilling, which is especially obvious when the size is small, especially important is that the static electricity of plastic products is difficult to eliminate, which brings difficulties to the process of taki...
