Special composite emulsion for paperboard for packaging carrier tape

Abstract

The invention provides a special composite emulsion for a paperboard for packaging a carrier tape. The special composite emulsion comprises, by weight, 5-40% of polyvinyl alcohol, 5-50% of a styrene acrylate emulsion, 5-50% of a butadiene styrene emulsion, 5-30% of starch paste and 1-5% of a lubricant, and the sum of the weight percentages of the components is 100%. The special composite emulsion for the paperboard for packaging the carrier tape is directly applied to the surface of carrier tape raw paper, so that the surface strength and smoothness of the paper can be greatly improved, the powder falling of the paper is remarkably improved, and the stripping force of the paper and a sealing tape is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of paper carrier tape preparation, in particular to a special composite emulsion for cardboard used for tape carrier packaging. Background technique [0002] At present, the cardboard used for carrier tape packaging in the market is mainly produced by foreign monopolies such as Japan. It is mainly used as the packaging carrier of SMD components such as resistors, capacitors, diodes, relays, and mobile phone parts. The use of paper carrier tape has low cost and paper Good quality resilience, paper material recycling and environmental protection, etc., but paper carrier paper punching and cutting is easy to produce paper powder to pollute electronic components, and carrier tape needs high surface strength when peeling off the packaging tape, so the development The special compound emulsion for carrier paper is applied on the paper surface to solve the key properties of the carrier paper such as bonding strengt...

[0002] At present, the cardboard used for carrier tape packaging in the market is mainly produced by foreign monopolies such as Japan. It is mainly used as the packaging carrier of SMD components such as resistors, capacitors, diodes, relays, and mobile phone parts. The use of paper carrier tape has low cost and paper Good quality resilience, paper material recycling and environmental protection, etc., but paper carrier paper punching and cutting is easy to produce paper powder to pollute electronic components, and carrier tape needs high surface strength when peeling off the packaging tape, so the development The special composite emulsion for carrier paper is applied on the paper surface to solve key properties such as bonding strength, powder shedding, and surface strength of the carrier paper. Domestic paper manufacturers develop carrier paper to break foreign monopoly and benefit China's economic development.
