Problems solved by technology

[0002] Weaving products have existed in our country since ancient times. Weaving exquisite artworks and daily necessities with the materials at hand. With the improvement of people's living standards, there has been great interest in weaving artworks and daily necessities. The weaving art industry It has also gradually developed, from the original straw weaving and willow weaving products to new materials or paper weaving products. Paper weaving products have high flexibility, which is obviously different from straw weaving and willow weaving, and has a larger market. However, the current weaving paper materials Usually, it is used after simple treatment. As the use time increases, the paper woven artwork absorbs more moisture, and it is easy to soften and deform after absorption. Even if it is re-dried, it will appear bubbling or twisting, which will affect the quality of the paper woven product. Artistry and practicality seriously restrict the development of paper weaving materials

Embodiment 1

[0012] A hardened coating for weaving paper, made of the following raw materials in parts by weight: 8 parts of polyurethane, 6 parts of petroleum resin, 7 parts of hydroxypropyl methylcellulose, 10 parts of polyacrylate latex, glutinous rice 6 parts, 5 parts of cotton seed husk, 3 parts of lithium carbonate, 3 parts of boron nitride fiber, 3 parts of tert-butyl peroxybenzoate, 4 parts of fluorocarbon emulsion, 4 parts of ammonium persulfate, 2 parts of acrylic acid, 39 parts of water .

[0013] A preparation method for a hardened coating of paper for weaving, comprising the following steps:

[0014] (1) Put the cotton seed husk in boiling water equivalent to 5 times its weight and cook for 1.5-2 hours, then continue to add glutinous rice and cook for 35-45 minutes, stir once every 15 minutes during the cooking process, boil After the cooking is completed, filter out the soup juice, mash the filtered mixture for 5-8 minutes, then add 20% by weight of sodium hydroxide solution...

Embodiment 2

[0018] A hardened coating of paper for weaving, made of the following raw materials in parts by weight: 6 parts of polyurethane, 8 parts of petroleum resin, 6 parts of hydroxypropyl methylcellulose, 12 parts of polyacrylate latex, glutinous rice 8 parts, 3 parts of cotton seed husk, 1 part of lithium carbonate, 2 parts of boron nitride fiber, 3 parts of tert-butyl peroxybenzoate, 2 parts of fluorocarbon emulsion, 6 parts of ammonium persulfate, 1 part of acrylic acid, 42 parts of water .

[0019] Its preparation method is the same as in Example 1.

Embodiment 3

[0021] A hardened coating for weaving paper, made of the following raw materials in parts by weight: 10 parts of polyurethane, 5 parts of petroleum resin, 4 parts of hydroxypropyl methylcellulose, 10 parts of polyacrylate latex, glutinous rice 5 parts, 6 parts of cotton seed hulls, 1 part of lithium carbonate, 3 parts of boron nitride fiber, 4 parts of tert-butyl peroxybenzoate, 2 parts of fluorocarbon emulsion, 3 parts of ammonium persulfate, 2 parts of acrylic acid, 45 parts of water .

[0022] Its preparation method is the same as in Example 1.

[0023] After the hardened coating prepared in the examples is used on the surface of the weaving paper, the thickness is 0.02-0.04mm, which increases the hardness and wear resistance of the weaving paper. Under the condition of -10-40°C, the hardness changes little, It has good water resistance and can be used for more than 15 years without deformation, which improves the durability and weather resistance of paper woven products.

Abstract

The invention discloses a hardening coating for weaving paper and a preparation method thereof. The hardening coating is prepared from the following raw materials: polyurethane, petroleum resin, hydroxypropyl methyl cellulose, polyacrylate latex, sticky rice, cotton seed shell, lithium carbonate, boron nitride fibers, tert-Butyl peroxybenzoate, fluorocarbon emulsion, ammonium persulfate, crylic acid and water. Compared with the prior art, the hardening coating has the advantages that sticky rice and cotton seed shell are treated together so that the caking property and tensile strength of cellulose and lignin in the cotton seed shell are increased; a sodium hydroxide solution is used for treating after mud smashing, so that the surface roughness of the fiber is increased; the wetting effect of the fiber is increased; the caking ability of the product is further enhanced; lithium carbonate can increase the hardening speed of the product after use; the weaving paper surface has better waterproof property and mildew resistance; the overall toughness and hardness both reach the weaving standard; after long-term use, the hardening coating does not absorb moisture or deform; the artistry of the paper weaved products can be maintained for a long time; the practicability is strong.
