Method for manufacturing thermo-sensitive industrial precoating base paper

Abstract

The invention relates to the technical field of papermaking, and in particular relates to a method for manufacturing three-proofing thermo-sensitive precoating base paper. A method for manufacturing thermo-sensitive industrial precoating base paper comprises the following steps: making paper; directly carrying out back gluing and front on-machine coating and precoating for 6-9g / m<2> through drying; and calendaring and curling to form the three-proofing thermo-sensitive precoating base paper, of which the front surface can be directly coated with a thermo-sensitive finishing-coat and a top coat after drying. Thermo-sensitive coating equipment does not need to be transformed; and the high-grade thermo-sensitive paper can be produced by existing equipment conditions.

Description

technical field

[0001] The invention relates to the technical field of papermaking, in particular to a manufacturing method of three-proof thermal paper. Background technique

[0002] After 2000, with the development of the economy and the improvement of people's living standards, the application field of thermal paper has been gradually developed, and then the production base of thermal paper has been continuously expanded at home and abroad. After entering 2013, the thermal paper competition has become fierce, and the profit of low-end thermal paper is getting lower and lower. Most manufacturers have transformed into high-grade thermal paper with higher profits, and high-end thermal paper is mainly based on three-proof thermal paper, which has high requirements on the coating machine and needs to be coated three times. The thermal coating machine has only two coating heads, and it needs to be re-coated once to obtain the three-proof thermal paper, so the waste is large, a...
