Problems solved by technology

However, at present, the surface of the cast stationery products is relatively rough. For example, inkstones and town rulers are difficult to have a warm and delicate feel.
And because most of the stationery is placed on the table for use, there is a risk of falling and breaking, and the current cast stationery cannot meet the relevant hardness requirements, resulting in it being directly broken and scrapped after falling, and the service life is low

Embodiment 1

[0040] S1: In the composite material, 12 parts of unsaturated polyester resin, 10 parts of glass fiber, 0.8 part of color paste, 4 parts of low shrinkage agent, 0.5 part of process additive, and 60 parts of filler, put each component in this weight part into the container, and stir until evenly mixed to obtain a mixed slurry;

[0041] S2: pour the mixed slurry into the mold cavity of the mold, and press molding, wherein the mold pressure is 56cm when pressing 2 / kg, the mold temperature is 55°C, and the pressing time is 0.8h;

[0042] S3: Take out the molding blank from the mold, and cool it naturally to get the inkstone made of composite material.

Embodiment 2

[0044] S1: In the composite material, 16 parts of unsaturated polyester resin; 12 parts of glass fiber; 1 part of color paste; 7 parts of low shrinkage agent; into the container, and stir until evenly mixed to obtain a mixed slurry;

[0045] S2: Pour the mixed slurry into the mold cavity of the mold, press molding, and the mold pressure is 70cm 2 / kg, the mold temperature is 45°C, and the pressing time is 1h;

[0046] S3: Take out the formed stationery from the mold, and let it cool down naturally to obtain an inkstone made of composite material.

Embodiment 3

[0048] S1: In the composite material, 15 parts of glass fiber; 2 parts of color paste; 10 parts of low shrinkage agent; 1.5 parts of process additive; Homogenously, to obtain a mixed slurry;

[0049] S2: Pour the mixed slurry into the cavity of the mold and press to form, wherein the mold pressure is 50cm during pressing 2 / kg, the mold temperature is 60°C, and the pressing time is 1h;

[0050] S3: Remove the blank from the mold and cool it naturally to obtain an inkstone made of composite materials.

[0051] Among the above-mentioned embodiments 1 to 3, in addition to being used to make inkstones, it can also be used to make stationery such as paperweights. In addition, in the technique of the above-mentioned embodiment, after the calcium powder and quartz powder as fillers are all passed through 1000 sieves, they are put into the container and stirred, so that the fineness of calcium powder and lime can be increased, thereby improving the smoothness of the stationery surfa...

Abstract

The invention relates to the field of manufacturing of stationery commodities, in particular to a composite material of the stationery commodities and a process for manufacturing the stationery commodities and an inkstone by using the composite material. Specifically, the composite material comprises the following components in parts by weight: 12-20 parts of unsaturated polyester resin, 10-15 parts of glass fiber, 0.8-2 parts of color paste, 4-10 parts of a low shrinkage agent, 0.5-1.5 parts of a process aid and 60-65 parts of a filler, wherein the filler is one or more of calcium powder and quartz powder, and the process aid comprises a curing agent and a release agent. The process for manufacturing the stationery commodity comprises the following steps: putting the components of the composite material in parts by weight, and stirring until the components are uniformly mixed; and pouring into a mold cavity of the mold, carrying out compression molding, and finally naturally cooling to obtain the stationery commodity. The study article prepared by adopting the composite material and the process has mild and fine hand feeling and soft gloss, and also has relatively high hardness, toughness and wear resistance, so that the study article has a wide application prospect.

Description

technical field [0001] The invention relates to the field of stationery production, in particular to a composite material for stationery and a process for making stationery and inkstone. Background technique [0002] Calligraphy is an artistic expression of the beauty of characters unique to China and neighboring countries and regions that have been deeply influenced by Chinese culture. When writing, the four treasures of the study (pen, ink, paper, and inkstone) are indispensable tools. At the same time, a ruler for pressing paper and a pen holder for hanging pens are also needed when writing. Among them, inkstones and town rulers are mostly made of stone, while pen holders are mostly made of wood. [0003] With the development of modern technology, the above-mentioned stationery can already be mass-produced through mold casting technology. However, at present, the surface of the cast stationery products is relatively rough. For example, inkstones and town rulers are diff...
