Abstract

The invention belongs to the technical field of water-writing newsprint paper and in particular relates to special water-writing newsprint paper for painting and calligraphy practice and a manufacture process of the special water-writing newsprint paper. The special water-writing newsprint paper comprises a black newsprint paper layer, wherein an upper water-based pigment layer is arranged on the upper surface of the black newsprint paper layer, and a lower water-based pigment layer is arranged on the lower surface of the black newsprint paper layer. The process comprises the following steps: step 1, using original pulp or waste paper as a raw material, carrying out repulping, pulp-mixing and paper making, and thus obtaining a diluted pulp material; step 2, adding carbon black in the pulp material in the step 1, and thus manufacturing a black pulp material; step 3, distributing the black pulp material in the step 2 through a headbox, and carrying out wet end forming; step 4, rolling and compositely pressing the pulp after wet end forming in the step 3, prebaking for drying, carrying out surface flattening, post-baking for drying, winding paper, and thus obtaining black newsprint paper. The special water-writing newsprint paper has the characteristics of being simple in process, low in cost, good in rice paper simulation effect, energy-saved and environmentally-friendly. The newsprint paper similar with rice paper is used as a carrier, and clean water is used as a medium, so that the special water-writing newsprint paper can be repeatedly used, is good in writing feel and can meet the demand of painting and calligraphy lovers.

Description

technical field [0001] The invention belongs to the technical field of water-written newsprint, and in particular relates to a special water-written newsprint for calligraphy and painting practice and a manufacturing process thereof. Background technique [0002] Traditional water writing paper is based on ordinary offset paper, which is coated on one side or both sides for practitioners to use. Although this water writing paper solves the problems of repeatable writing, energy saving and environmental protection; but due to the production process At least two to six times of coating processes are required to make it more expensive. In addition, this kind of water writing paper has a poor development effect after writing, and cannot bring real imitation effects to practitioners; calligraphy lovers In the long-term practice process, it is found that waste newsprint as a writing carrier can achieve the effect of imitating propaganda and the cost is low, but a large number of w...
