Problems solved by technology

TJ-1 special latex paper is used as the substrate for processing super-coated TJ-1 special latex sandpaper. At present, TJ-1 special latex paper cannot be used for continuous papermaking and internal sizing on a multi-net multi-cylinder paper machine. The production is completed, and many downstream product users urgently request the company to develop as soon as possible

Embodiment Construction

[0006] The present invention is further described below, but not limiting the present invention.

[0007] The production process of TJ-1 special latex paper base paper of the present invention:

[0008] The main raw material is bleached kraft pulp board with a content of 100%, and the following are added according to the weight percentage: 10%-12% light calcium, and water, which are pulped by a hydraulic pulper, and then enter the pre-grinding pool, and pass through the double disc Refining with a mill, and then enter the pulp tank, add 0.4%-0.6% PAE into the pulp tank, then pump into the pulp mixing box, add 0.3%-0.5% AKD and 0.3%-0.5% waterproof and oil-repellent agent, and then enter the degreaser The slag is removed by the slag machine, and then 0.1%-0.2% dye retention aid is added after the slag removal, and then enters the screen section, press section and drying section through the pulp pump and rotor screen, and then enters the drying section and calendering after surf...

Abstract

The invention discloses a production method of the TJ-1 special latex paper. The invention is characterized in that the method is that two working procedures of paper making and inner sizing are completed continuously in a multi-net and multi-cylinder paper machine: the latex is sprayed onto a wet shaped paper sheet by a dedicated sprayer on a circular-net pressure molding machine, and latex penetrates quickly to fill the paper with the latex component; then the surface sizing is conducted inside the paper machine, and a single side of the paper sheet is coated with the even and thin latex to reach the liquid adding performance. The TJ-1 special latex paper produced with the invention is applicable for polishing in the sectors of automobile, plane, shipbuilding, machinery, light industry, leather making, furniture, decoration, and so on.

Description

technical field [0001] The invention relates to a production method of TJ-1 special latex paper. Background technique [0002] TMA water sand base paper is a special technology supporting paper for the production of high-grade water-resistant sandpaper for the coated abrasive industry. The main raw material is unbleached kraft softwood pulp, and the auxiliary materials are self-developed CS cationic starch. 8K. TJ-1 special latex paper is used as the substrate for processing super-coated TJ-1 special latex sandpaper. At present, TJ-1 special latex paper cannot be used for continuous papermaking and internal sizing on a multi-net multi-cylinder paper machine. After the production is completed, many downstream product users urgently request the company to develop it as soon as possible. Contents of the invention [0003] The purpose of the present invention is to provide a kind of TJ-1 special latex paper production method, the production method of the present invention i...
