Environment friendly coated imitation canvas and preparation method thereof

Abstract

The invention relates to an environment friendly coated imitation canvas and a preparation method thereof. The canvas is formed by taking high density weaving terylene plain cloth as base material, wherein high density weaving terylene plain cloth takes high-strength polyester yarns as raw material and environment friendly coated imitation sizing agent taking water-solubility starch resin and additive as raw materials is spread and sprayed the surface thereof. The size of granules of water-solubility starch resin is 60 to 180mum; and additive comprises optical bleaching agent, silicone deformer, phosphorus flame retardant, isothiazolinone antibiosis and antifungal agent, E3280 antistatic agent and titanium serving as opacifier. In the preparation process, firstly, base cloth weaving is finished and sizing agent is prepared according to a prescription for sandy application, and then pretreatment, ironing, sizing, knife scraping, drying, cooling and surface treatment are carried out on base cloth in a multifunction coated imitation production line. The canvas has excellent painting excellent, is not only suitable for hand painting, but also suitable for jet drawing, and has longer service life.

Description

technical field [0001] The invention belongs to a canvas technology, and in particular relates to an environment-friendly canvas product suitable for both hand-painting and inkjet painting, and also relates to a preparation method of the product. Background technique [0002] Traditional painting is usually carried out on paper, but because the paper is very thin, it often needs a series of complicated processes to become thick and stiff, easy to hang and frame. For example, after painting on rice paper, it must go through the processes of supporting the heart, backing, and bordering. At the same time, when Xuan paper is used for freehand Chinese painting, the wet ink that has just been put on it will become lighter and lighter after drying, which brings great difficulties for the painter to observe the depth of the tone. In addition, because the rice paper is thin and not strong, excessive drawing force or repeated rubbing can easily cause rotten paper and heavy dirt, and ...

Problems solved by technology

And there are reports in relevant literature on the production process of the canvas, such as Tang Weicai, who soaked the chemical fiber fabric in the mixed liquid of water glass solution and toner, and processed it to make it, but the ink absorption of this method and the strength of the canvas need to be improved. ; Lining paper and ordinary cloth (cotton cloth, linen cloth or chemical fiber cloth) are bonded into a cloth base by an adhesive (alum and paste), and then painted with a layer of surface paint. The canvas is mainly for oil painting, but it is not ideal for hand-painted paintings; Zheng Shiqing uses cotton gauze as the base material, and coats it with a shaped colored paste layer, and then coats it with a glue layer. As a base fabric, the strength of the canvas is relatively low, and it is mainly aimed at craft oil paintings, and the applicable surface is narrow; there are other literature reports on chemical fiber fabrics, glass fiber cloths or cotton cloths that adhere to PVC surfaces or use various polymer emulsions to compound them. The production process of preparing canvas, and the production process of preparing similar canvas materials by using polyester material and scraping PVC coating, the main disadvantage of these two methods is that after covering the base fabric with PVC film or applying polymer emulsion, The effect is flat, although it can be used as a spray painting canvas, but for hand-painted canvas, it cannot reflect the texture of the base fabric itself, and the expression effect is greatly reduced
