Abstract

The invention relates to immersion MeiWen base paper and its manufacturing technique. The immersion MeiWen base paper adopts 100% import wood pulp and paper technology to form. At lest its one surface is immersing 8-12g/m2 import latex layer. Its manufacturing technique includes the following steps: disintegrating; pulping, adding auxiliary materials; forming; dehydrating; vat pre-drying; cocking; infrared ray, two cylinder drying; taking-up; rewing parting cut; forming the MeiWen body paper; dipping it into import latex to make its surface form 8-12g/m2 import latex layer; drying; rolling; re-rolling cutting to complete the manufacturing technique. The invention has the advantages of simple technique, reliable product quality, satisfying userí»s demand, enlarging product using range, and convenient for popularization and application.

Description

technical field [0001] The invention relates to an impregnated textured base paper and a production process, belonging to the technical field of papermaking and paper product processing and production. Background technique [0002] Masking base paper is a special paper with high technical content and high added value, and it is the first basic product of masking tape. Masking tape is a high-tech decoration and spray masking paper, which is widely used in interior decoration, spray painting of household appliances and spray masking of high-end luxury cars. Its color separation effect has clear and clear boundaries, no glue left, and also has an arc art effect, which has brought a new technological revolution to the decoration and spraying industries. At present, the production of textured base paper is still technically blank in China, and all base paper used in China is imported from the United States, France, Brazil, and Italy. According to the information provided by the...
