Description

Technical Field

[0001] The invention relates to the technical field of papermaking, and in particular to a method for preparing rice paper-like paper. Background Art

[0002] Xuan paper is a kind of paper for calligraphy and painting that has been used in my country since ancient times. It has been loved by calligraphers and painters because of its excellent penetration and lubrication properties. However, traditional Xuan paper has the problems of weak strength, complex process and short shelf life. In addition, according to the content of sandalwood bark, Xuan paper is mainly divided into three types: cotton material, pure skin and special clean. The sandalwood bark content of cotton material Xuan paper is about 40%, the sandalwood bark content of pure skin Xuan paper is about 60%, and the sandalwood bark content of special clean Xuan paper is as high as 80%. The higher the sandalwood bark content, the greater its cost.

[0003] In view of this, it is necessary to design a preparation method of rice paper-like to solve the above problems. Summary of the invention

[0004] In view of the defects of the above-mentioned prior art, the purpose of the present invention is to provide a method for preparing a rice paper-like paper, which uses a mixture of polyquaternium-7, polyoxyethylene alkylamine, sodium carboxymethyl cellulose and water as an auxiliary liquid, immerses a non-woven fabric in a finishing liquid (the auxiliary liquid is dissolved in water) for finishing, and then composites it with newly formed sandalwood paper, and by changing the component concentration of the finishing liquid, the hydrophilicity and hydrophobicity of the rice paper-like paper are adjusted, and the ink-wetting property of the rice paper-like paper is adjusted to achieve the effect of cooked rice paper and raw rice paper; the strength of the rice paper-like paper is improved, and the disadvantage of the weak strength of traditional rice paper is solved; and the amount of sandalwood bark used is reduced, and the amount of sandalwood bark used only accounts for about 10% of the total mass of the rice paper-like paper, thereby saving costs.

[0005] To achieve the above object, the present invention provides a method for preparing a rice paper-like product, comprising the following steps:

[0006] S1. Soaking and softening the sandalwood bark, and then crushing the softened sandalwood bark to make a slurry;

[0007] S2. Shake the support plate in the slurry obtained in step S1 for 2-4 times to form a piece of sandalwood paper on the support plate;

[0008] S3. The nonwoven fabric is immersed in the finishing liquid, immersed for 10-30min and then passed through the rolling car, maintaining a liquid rate of 100%-200%; the finishing liquid is obtained by dissolving the additive liquid in water; the additive liquid is a mixture of polyquaternium-7, polyoxyethylene alkylamine, sodium carboxymethyl cellulose and water;

[0009] S4. Cover the treated non-woven fabric obtained in step S3 on the newly formed sandalwood paper obtained in step S2, apply a predetermined pressure after the two are closely attached, and then dry them to obtain a rice paper-like paper.

[0010] As a further improvement of the present invention, in step S3, the mass fraction of polyquaternium-7 in the auxiliary agent liquid is 20%-30%, the mass fraction of polyoxyethylene alkylamine is 1%-5%, the mass fraction of sodium carboxymethyl cellulose is 0.1%-1%, and the rest is deionized water.

[0011] As a further improvement of the present invention, in step S3, the finishing liquid is the auxiliary liquid diluted 100 times with water.

[0012] As a further improvement of the present invention, in step S4, after the non-woven fabric and the sandalwood paper are attached to each other, it is ensured that there are no bubbles between the two, and when pressure is applied, the liquid carrying rate is maintained at 100%-200%; the predetermined pressure is 0.6-2.6kg.

[0013] As a further improvement of the present invention, in the slurry of step S1, the ratio of sandalwood bark to water is sandalwood bark: water = 1g: (100-1000)L.

[0014] As a further improvement of the present invention, the non-woven fabric is made of one or more of cotton, polyester, and wood pulp.

[0015] As a further improvement of the present invention, in step S1, the soaking time of the sandalwood bark is 10-20 minutes.

[0016] As a further improvement of the present invention, in step S1, the sandalwood bark is sun-dried sandalwood bark.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention provides a method for preparing a rice paper-like product, wherein a mixture of polyquaternium-7, polyoxyethylene alkylamine, sodium carboxymethyl cellulose and water is used as an auxiliary liquid, and a non-woven fabric is immersed in a finishing liquid (the auxiliary liquid is dissolved in water) and then compounded with newly formed sandalwood paper. Compared with traditional rice paper, the strength of the non-woven fabric is improved, thereby solving the disadvantage of the traditional rice paper having a weak strength.

[0019] 2. The present invention adjusts the hydrophilicity and hydrophobicity of rice paper and the ink-wetting property of rice paper by changing the component concentration of the finishing liquid, thereby achieving the effect of cooked rice paper and raw rice paper; at the same time, polyquaternium-7 and polyoxyethylene alkylamine can form a multi-salt complex, which increases the tightness between the non-woven fabric and the sandalwood bark in the viscous solution of sodium carboxymethyl cellulose, making the non-woven fabric and the sandalwood bark difficult to separate.

[0020] 3. The preparation method of the present invention has a simple process and reduces the amount of sandalwood bark used. The amount of sandalwood bark used only accounts for about 10% of the total mass of the rice paper-like paper, thus saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] S2. Shake the support plate in the slurry obtained in step S1 for 2-4 times to form a piece of sandalwood paper on the support plate;

[0036] S3. The nonwoven fabric is immersed in the finishing liquid, immersed for 10-30min and then passed through the rolling car, maintaining a liquid rate of 100%-200%; the finishing liquid is obtained by dissolving the additive liquid in water; the additive liquid is a mixture of polyquaternium-7, polyoxyethylene alkylamine, sodium carboxymethyl cellulose and water;

[0037] The mass fraction of polyquaternium salt-7 in the additive liquid is 20%-30%, the mass fraction of polyoxyethylene alkylamine is 1%-5%, the mass fraction of sodium carboxymethyl cellulose is 0.1%-1%, and the rest is deionized water.

[0038] The material of non-woven fabric is one or more of cotton, polyester and wood pulp.

[0039] Among them, the finishing liquid is the auxiliary liquid diluted 100 times with water.

[0040] S4. Cover the treated non-woven fabric obtained in step S3 on the newly formed sandalwood paper obtained in step S2, apply a predetermined pressure after the two are closely attached, and then dry them to obtain a rice paper-like paper.

[0042] The invention uses a mixture of polyquaternium-7, polyoxyethylene alkylamine, sodium carboxymethyl cellulose and water as an auxiliary liquid, immerses nonwoven fabric in the finishing liquid (the auxiliary liquid is dissolved in water) for finishing, and then compounds the nonwoven fabric with newly formed sandalwood paper, and adjusts the hydrophilicity and hydrophobicity of the rice paper-like paper and the ink-wetting property of the rice paper-like paper by changing the component concentration of the finishing liquid, thereby achieving the effects of cooked rice paper and raw rice paper; the strength of the rice paper-like paper is improved, and the disadvantage of the traditional rice paper being relatively weak in strength is solved; and the amount of sandalwood paper used is reduced, and the amount of sandalwood paper used only accounts for about 10% of the total mass of the rice paper-like paper, thereby saving costs.

[0043] The preparation method of the rice paper-like product provided by the present invention is described below with reference to specific embodiments.

[0044] Example 1

[0045] Embodiment 1 provides a method for preparing a rice paper-like product, comprising the following steps:

[0046] S1. Take 20g of sandalwood bark and soak it for 10 minutes to soften it; then, crush the softened sandalwood bark and add 6L of deionized water, and stir evenly to make a slurry.

[0047] S2. Shake the support plate in the slurry twice to form a piece of sandalwood paper on the support plate.

[0048] S3. Take 2g of the additive liquid and add it to 1L of deionized water, stir evenly to obtain a finishing liquid with a concentration of 2g / L. In the additive liquid, the mass fraction of polyquaternium-7 is 30%, the mass fraction of polyoxyethylene alkylamine is 2%, and the mass fraction of sodium carboxymethyl cellulose is 0.5%. After the cotton non-woven fabric is immersed in the finishing liquid for 20 minutes, it is passed through a roller to maintain a liquid carrying rate of 200%.

[0049] S4. The treated cotton nonwoven fabric is covered on the newly formed sandalwood paper, and a certain pressure (0.6kg) is applied after the two are close together, and the liquid carrying rate is maintained at 200%, and the paper is dried at 80°C to obtain a rice paper with good ink wetting properties, which can achieve the effect of raw rice paper painting and calligraphy. The situation of painting on the rice paper obtained in Example 1 is as follows Figure 1 shown.

[0050] Example 2

[0051] Example 2 provides a method for preparing rice paper-like material, which is different from Example 1 mainly in that the concentration of each component in the auxiliary agent liquid is changed. The details are as follows:

[0052] S1. Soak 20g of sandalwood bark for 10 minutes to soften it. Then, crush the softened sandalwood bark and add 6L of deionized water, stirring evenly to make a slurry;

[0053] S2. The tray is placed in the slurry and shaken twice to form a piece of sandalwood paper on the tray;

[0054] S3. Take 2g of the auxiliary liquid and add it to 1L of deionized water, stir evenly to obtain a finishing liquid with a concentration of 2g / L. The mass fraction of polyquaternium-7 in the auxiliary liquid is 10%, the mass fraction of polyoxyethylene alkylamine is 10%, and the mass fraction of sodium carboxymethyl cellulose is 1%. The polyester non-woven fabric is immersed in the finishing liquid for 30 minutes and then passed through a roller to maintain a liquid carrying rate of 150%.

[0055] S4. Cover the treated polyester nonwoven fabric on the newly formed sandalwood paper, apply a certain pressure (2.6kg) after the two are close together, maintain 100% liquid carrying rate, and dry at 80℃. That is, a rice paper with general ink absorption property is obtained, which can achieve the effect of cooked rice paper for calligraphy and painting. The situation of painting on the rice paper obtained in Example 2 is as follows Figure 2 shown.

[0056] Example 3

[0057] Example 3 provides a method for preparing rice paper-like material, which is mainly different from Example 1 in that the concentration of each component in the auxiliary agent liquid is changed. The details are as follows:

[0058] S1. Take 20g of sandalwood bark and soak it for 10 minutes to soften it. Then, crush the softened sandalwood bark and add 6L of deionized water, and stir evenly to make a slurry.

[0059] S2. The tray is placed in the slurry and shaken twice to form a piece of sandalwood paper on the tray;

[0060] S3. Take 2g of the additive liquid and add it to 1L of deionized water, stir evenly to obtain a finishing liquid with a concentration of 2g / L. In the additive liquid, the mass fraction of polyquaternium-7 is 20%, the mass fraction of polyoxyethylene alkylamine is 5%, and the mass fraction of sodium carboxymethyl cellulose is 0.5%. After the polyester non-woven fabric is immersed in the finishing liquid for 15 minutes, it is passed through a roller to maintain a liquid carrying rate of 100%.

[0061] S4. Cover the treated polyester nonwoven fabric on the newly formed sandalwood paper, apply a certain pressure (1.8kg) after the two are close together, maintain a 150% liquid rate, and dry at 80℃. This will obtain a rice paper with moderate ink absorption, which can achieve the painting and calligraphy effect of semi-cooked rice paper. The painting on the rice paper obtained in Example 3 is as follows: Figure 3 shown.

[0062] Comparative Example 1

[0063] Comparative Example 1 provides a method for preparing a rice paper-like paper. The main difference from Example 1 is that no polyquaternium-7 is added to the auxiliary agent solution in step S3. The rest is substantially the same as Example 1 and will not be described in detail here. Figure 4 shown.

[0064] Comparative Example 2

[0065] Comparative Example 2 provides a method for preparing a rice paper-like paper. The main difference from Example 1 is that no polyoxyethylene alkylamine is added to the auxiliary agent solution in step S3. The rest is substantially the same as Example 1 and will not be described in detail here. Figure 5 shown.

[0066] Comparative Example 3

[0071]

[0072]

[0073] When the mass fraction of polyquaternium salt-7 is higher than 30% (Comparative Example 4), the ink is not easy to spread when painting on the prepared rice paper; when the mass fraction of polyoxyethylene alkylamine is higher than 5% (Comparative Example 5), the calligraphy and painting on the prepared rice paper are uneven.

[0074] In summary, the present invention uses a mixture of polyquaternium-7, polyoxyethylene alkylamine, sodium carboxymethyl cellulose and water as an auxiliary liquid, immerses the non-woven fabric in the finishing liquid (the auxiliary liquid is dissolved in water) for finishing, and then compounds it with the newly formed sandalwood paper, and by changing the component concentration of the finishing liquid, the hydrophilicity and hydrophobicity of the rice paper-like paper are adjusted, and the ink-wetting property of the rice paper-like paper is adjusted to achieve the effect of cooked rice paper and raw rice paper; the strength of the rice paper-like paper is improved, and the disadvantage of the weak strength of traditional rice paper is solved; and the amount of sandalwood bark used is reduced, and the amount of sandalwood bark used only accounts for about 10% of the total mass of the rice paper-like paper, thereby saving costs.

[0075] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
