Embodiment Construction

[0025] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0026] A preparation method for a stone paper copybook, the stone paper copybook is to successively coat a layer of bottom white layer, a layer of light black ink layer, a layer of black ink layer and a layer of color development layer on a stone paper, each layer Both are coated by the following steps:

[0027] First, the preparation for coating includes steps 1 to 4.

[0028] Step 1: Preheat the coating machine; it includes five temperature sections, among which, temperature sections 1 to 4 are gradually heating sections, and section 5 is a cooling section. Such as: 55 degrees for one stage, 60 degrees for the second stage, 65 degrees for the third stage, 75 degrees for the fourth stage, and 60 degrees for the fifth stage.

[0029] While the coating machine is preheating, the paint can be prepared (if the p...

Abstract

The invention discloses a preparation method of a stone paper copybook. According to the stone paper copybook, stone paper is sequentially coated with a bottom white layer, a light black ink layer, a black ink layer and a developing layer. Coating of each layer comprises the following steps that firstly, a coating machine is preheated; secondly, the stone paper is put onto the coating machine, and the tension of the paper is adjusted; thirdly, coating is put into a raw material groove of the coating machine; fourthly, the angle of a scraping knife is adjusted till the angle ranging from 40 degrees to 50 degrees is formed between the relative positions of the scraping knife and an anilox roller, and the air pressure value of the scraping knife is adjusted according to the paper feed speed; fifthly, the coating machine operates, and the stone paper is subjected to corona treatment; sixthly, coating is started, the rotating direction of the anilox roller is opposite to the paper feed direction, and after the stone paper is coated with the coating, the coating is scraped to be level by the scraping knife; seventhly, drying is carried out; eighthly, cooling is carried out; and ninthly, winding is carried out.

Description

technical field [0001] The invention relates to a cultural school article, in particular to a method for preparing a stone paper copybook. Background technique [0002] Traditional calligraphy and painting practice paper is ordinary white board paper or rice paper, which can only be used once, and the waste of paper is serious. At present, there are some reusable water writing papers on the market. The existing water writing papers are divided into physical reaction and chemical reaction. Types of. The surface of physical reaction water writing paper is not coated with any chemical raw materials, and the appearance of the paper is dark green. The surface has a rough feeling similar to rice paper naturally formed by pulp fibers, and has the characteristics of water seepage and moistening. According to the principle of spectral change after contact with water, when a brush is dipped in water to write on paper, the handwriting will appear ink-colored. The surface of chemical ...
