Abstract
The invention discloses a preparation method of a high-grade thermosensitive base paper. According to the preparation method, softwood pulp and hardwood pulp are respectively subjected to beating, pulp mixing and auxiliary material adding, wet paper sheet papermaking, before-drying, surface sizing, after-drying, press polishing and finishing, and the like. Optimization of pulp composition and beating are carried out; functional chemical auxiliary agents are added into pulp; and at the same time, a lubricant is added into a surface sizing starch; paper machine parameters are adjusted based on actual production requirements; and the qualified high-grade thermosensitive base paper is prepared.
Description
Technical field
The present invention relates to a kind of manufacture method of high-grade thermosensitive body paper, belong to pulp technology for making paper.
Background technology
For heat-sensitive paper coating factory, thermosensitive body paper is the one industry body paper for being coated with thermo colour, is that paper mill is produced, does not possess color development function.The heat-sensitive paper having color development function just can be become after only having coating waste water.Common thermosensitive body paper is processed as that heat-sensitive paper needs to carry out primary coat, face is coated with, top is coated with and reverse side is fetched water four procedures.Thermosensitive body paper generally has good evenness, certain tensile strength, water imbibition and surface exquisiteness, meets the needs of thermo colour colour developing simultaneously.High-grade thermosensitive body paper is the industrial paper being specifically designed to the high-grade heat-sensitive paper of processing and manufacturing, this product except possessing the general characteristic of common thermosensitive body paper, also have several outstanding feature as: high-tensile, high internal bond strength, not containing high yield pulp, formation of sheet is good, outward appearance is fine and smooth, touch feeling is good.Yueyang Forest & Paper Co., Ltd. is engaged in research and development of products and the production of thermosensitive body paper for many years, mainly comprise three anti-thermosensitive body paper, whole wood pulp thermosensitive body paper etc., these products are mainly used in the anti-heat-sensitive paper of processing three and low and middle-grade heat-sensitive paper, also do not reach the quality requirement of the high-grade label heat-sensitive papers such as airline ticket, logistic industry, medical industry.The second half year in 2014, reach company's processing logistic label because of Zhenjiang, Jiangsu Wan Baorui and make the needs exporting high-grade heat-sensitive paper, my company is in conjunction with the experience of perennial product thermosensitive body paper, positive fit develops high-grade thermosensitive body paper, by exchange of technology and the understanding analysis to high-grade thermosensitive body paper Key Quality, start with from raw material in company technique center, by optimizing wet end furnish, improving refining pulp quality, rationally adding chemicals, optimizing surface glue-applying technique in slurry, successfully develop 70g/m in January, 2015 at PM9
2high-grade thermosensitive body paper, reaches customer requirement completely through on probation.
The several most outstanding feature of high-grade thermosensitive body paper is exactly tensile strength large (>=5.0KN/m), the large (>=400J/m of internal bond strength
2), air permeability suitable and stable (≤250ml/min), the large (>=0.83g/m of tightness
3), outward appearance exquisiteness, good hand touch, that client is coated with rear covering performance is good, colour-fast for a long time after full, the thermal printing of developing the color.
