Example Embodiment

[0006] The present invention will be further described below in conjunction with embodiments.

[0007] A production method of suede super-sensitive paper, which includes the basic steps of base paper production, double-sided coating processing, and sub-roll finishing:

[0008] (1) Production of base paper: The production of suede super-sensitive paper firstly guarantees the internal bonding strength, surface strength and smoothness from the base paper. The thickness of the entire width of the base paper is required to be uniform and the paper surface is smooth and delicate, laying the foundation for subsequent processing and production. Made with 100% wood pulp, of which 40% softwood pulp, 60% broad-leaved pulp, beating degree 40-45°SR, pulp sizing concentration 0.5-1.0%, base paper basis weight 80-200g / m 2 , Surface strength ≥ 12 grade, surface absorption 20-30g / m 2 , Smoothness of finished paper ≥ 30S;

[0009] (2) Double-sided coating processing: double-sided coating processing...

Abstract

The invention relates to a method for producing matte super-sensitive paper. The base paper of the matte super-sensitive paper is made of 100 percent of wood pulp, which comprises 40 percent of needle pulp and 60 percent of kargeleaf pulp; the degree of beating is between 40 and 45 degrees of SR, the pulping concentration of the pulp is between 0.5 and 1.0 percent, and the quantitation of the base paper is between 80 and 200g/m; the base paper is subjected to double-sided coating processing and bundling treatment, wherein the double-sided coating processing adopts roller-type feeding and air knife coating forming for one time, a finished product is double coated paper, and the single coating quantity is between 10 and 15g/m; and the coating comprises main pigment and a matte additive, wherein the main pigment is prepared by mixing kaoline and calcium carbonate according to the ratio of 1:1, the matte additive is G-365 commonly sold on markets, and the dosage of the matte additive accounts for 5 to 10 percent of the coating. The coating paper surface and the printed coating paper surface have no bright luster, and the paper surface touches slippery and smooth like floss and has visual effect of elegant printing matte; and the method has easy production and low production cost, and reduces processing steps under the condition of ensuring the printing effect.

Description

technical field [0001] The invention relates to a production process of special paper, in particular to a production method of suede supersensitive paper. Background technique [0002] We know that the coated paper currently on the market can be divided into two categories: one is low-quantity coated printing paper, whose quality is between coated paper and offset paper; the other is coated paper. Coated printing paper is made of copper plate base paper after coating and overpressure treatment. Its paper surface has high gloss and good printing reducibility, and was once welcomed by the printing industry. However, with the development of the market economy, people's aesthetic views are also constantly changing, and the gorgeous high-gloss feeling is gradually not accepted. On this basis, people began to develop high-grade coated super-sensitive paper. Coated super-sensitive paper abandons the concept of high gloss of coated paper, makes full use of the natural texture of b...
