Flexible word practicing board and preparation method thereof

Abstract

The invention provides a flexible word practicing board which solves the problems that an existing word practicing board made from a PP (Propene Polymer) material is extremely hard in texture and not suitable for directly and comfortably practicing on the word practicing board and influences the word practicing effect. The flexible word practicing board is prepared by heating a mixed raw material which contains EVA (Ethylene-Vinyl Acetate) resin granules and linear low density polyethylene high-pressure granules to a molten state and then carrying out calendering processing. The flexible word practicing board provided by the invention has the advantages of easy availability of raw materials and simple preparation process; the word practicing board with good integral flexibility and a flexible surface is obtained by matching the EVA resin granules with the LLDPE (Linear Low Density Polyethylene) high-pressure granules and has the advantages of good hand feeling, convenience for writing and good word practicing effect when a hard writing pen contacts the surface of the flexible word practicing board; furthermore, the word practicing boards with different colors are obtained by adding pigments to the mixed raw material; furthermore, the flexible word practicing board with a concave line can be obtained by adopting a mould with a concave line in the process course of the calendering processing and is more convenient for writing and word practicing and the word practicing effect is improved.

Description

technical field

[0001] The invention relates to the technical field of calligraphy practice, in particular to a soft calligraphy practice board and a preparation method thereof. Background technique

[0002] Chinese characters are one of the characters with the longest history, the richest content and the most perfect structure in the world. However, due to the relatively complicated structure of Chinese characters, it is generally difficult to master the essentials of writing them. Therefore, to write Chinese characters well, one must use a method to practice at the student stage. In the initial stage of Chinese character practice, the effective traditional methods are red tracing and temporary posting. Therefore, the handwriting board has become an important tool for practicing Chinese characters.

[0003] The material of the existing handwriting board is generally made of polypropylene (PP), which is too hard. The concave line handwriting board of hard material can be u...

Examples

Embodiment 1

[0026] A kind of soft calligraphy training board of this embodiment is prepared by calendering from a mixed raw material containing 30% EVA resin particles and 70% linear low density polyethylene high pressure particles by weight percentage. Specifically, it is achieved through the following steps:

[0027] Step 1, taking the following raw materials by weight percentage: 30% of EVA resin particles and 70% of linear low density polyethylene high pressure particles;

[0028] Step 2: Mix the raw materials weighed in step 1 evenly to obtain a mixed raw material, then heat the mixed raw material to 210-230°C to obtain a molten mixed raw material, add the molten mixed raw material to a calender, and then pass through a mold for calendering to obtain Soft handwriting board, complete the preparation of the soft handwriting board.

[0029] In addition, the molds used in the preparation process can be those used in the preparation process of existing calligraphy boards. Therefore, exis...

Embodiment 2

[0031] In this embodiment, on the basis of Example 1, plastic coloring powder is added to the mixed raw materials, and the amount of the coloring powder is 2% to 4% of the total weight of EVA resin particles and linear low-density polyethylene high-pressure particles.

[0032] The color of the specific coloring agent can be selected according to actual needs or user preferences, such as light green or beige, and existing commercially available products can be used.

Embodiment 3

[0034] A kind of flexible calligraphy training board of this embodiment is prepared by calender processing from mixed raw materials containing 50% EVA resin particles and 50% linear low-density polyethylene high-pressure particles by weight percentage. Specifically, it is achieved through the following steps:

[0035] Step 1, taking the following raw materials by weight percentage: 50% EVA resin particles and 50% linear low density polyethylene high pressure particles;

[0036] Step 2. Mix the raw materials weighed in step 1 to obtain a mixed raw material, then heat the mixed raw material to 210-230°C to obtain a molten mixed raw material, add the molten mixed raw material to the calender, and then pass through the mold on the calender to form a calender , get the soft handwriting board, and complete the preparation of the soft handwriting board.
