Description

Technical Field

[0001] The present invention relates to the technical field of resource reorganization and utilization technology, and in particular to a low-carbon and environmentally friendly sugarcane pottery ecological art board and a manufacturing process thereof. Background Art

[0002] In today's society, environmental awareness is growing, and the demand for green and sustainable products in the building and decoration materials sectors is becoming increasingly urgent. Traditional eco-friendly panels often rely on large amounts of wood resources during production, and adhesives may contain harmful substances such as formaldehyde, posing potential threats to the environment and human health. Sugarcane, a primary raw material for sugar production, produces significant quantities of bagasse after crushing. Statistics show that for every ton of sugar produced, approximately 2-3 tons of bagasse are generated. Disposing of this large amount of bagasse has long been a challenge for the sugar industry. In the past, some bagasse was directly incinerated, causing significant environmental pollution and wasting significant resources. Another portion was simply used for papermaking, but this has a low utilization rate and also poses pollution issues during the papermaking process. In fact, bagasse contains 30%-40% cellulose and approximately 20% hemicellulose of its total dry weight. This rich fiber resource offers the potential for high-value-added applications in other sectors. If sugarcane bagasse can be fully utilized and new materials can be developed, it will not only solve the problem of sugarcane bagasse disposal, but also provide a sustainable source of raw materials for related industries.

[0003] Ceramic materials have a long history of application in architecture and decoration, offering numerous advantages such as high hardness, wear resistance, corrosion resistance, fire resistance, and moisture resistance. However, traditional ceramic production typically requires high-temperature firing, consumes significant energy, and relies heavily on natural mineral resources. Reducing energy and resource consumption during production while preserving the excellent properties of ceramic materials has become a pressing challenge for the industry.

[0004] In this context, it is of great significance to combine sugarcane bagasse with natural clay to develop a low-carbon and environmentally friendly sugarcane pottery ecological art board. In view of the above reasons, this application proposes a low-carbon and environmentally friendly sugarcane pottery ecological art board and its production process. Summary of the Invention

[0005] The purpose of the present invention is to address the problems existing in the background technology and to provide a low-carbon and environmentally friendly sugarcane pottery ecological art board and its production process.

[0006] The technical solution of the present invention is: a low-carbon and environmentally friendly sugarcane pottery ecological art board, which is made of the following raw materials in parts by weight: 30-50 parts of sugarcane bagasse, 20-35 parts of pottery clay, 15-25 parts of water, and 8-15 parts of white latex;

[0007] The clay is selected from yellow clay or Nixing clay, with a particle size of ≤0.075mm and a purity of ≥90%.

[0008] The bagasse is crushed to a particle size of 0.5-2 mm.

[0009] Optionally, it is made from the following raw materials in parts by weight: 30 parts of bagasse, 20 parts of clay, 15 parts of water, and 8 parts of white latex;

[0010] Among them, the clay is yellow pottery mud, the clay particle size is ≤0.075mm, and the clay purity is ≥90%;

[0011] The bagasse is crushed to a particle size of 0.5 mm.

[0012] Optionally, it is made from the following raw materials in parts by weight: 50 parts of bagasse, 35 parts of clay, 25 parts of water, and 15 parts of white latex;

[0013] Among them, the clay is yellow pottery mud, the clay particle size is ≤0.075mm, and the clay purity is ≥90%;

[0014] The bagasse is crushed to a particle size of 2 mm.

[0015] Optionally, it is made from the following raw materials in parts by weight: 40 parts of bagasse, 30 parts of clay, 20 parts of water, and 12 parts of white latex;

[0016] Among them, the clay is Nixing clay, the clay particle size is ≤0.075mm, and the clay purity is ≥90%;

[0017] The bagasse is crushed to a particle size of 1 mm.

[0018] Optionally, the volume ratio of bagasse to clay is 1:3-1:5;

[0019] The weight ratio of the white latex to water is 1:8-1:10, and the total water content of the mixed materials is ≤30%.

[0020] Optionally, linen is pasted on the back of the eco-art board to improve the flexural strength of the eco-art board.

[0021] The present invention also proposes a low-carbon and environmentally friendly preparation process of sugarcane pottery ecological art board, comprising the following steps:

[0022] Step 1: Raw material pretreatment: Wash and dry the bagasse, crush it into 0.5-2mm pieces, and ferment it for 7-10 days to remove sugars;

[0023] Step 2: Clay slurry preparation: Mix clay and water in proportion and stir at 200-300 rpm for 10-15 minutes to form a uniform clay slurry;

[0024] Step 3: Fiber mixing: Add crushed bagasse to the clay slurry and stir at 150-250 rpm for 15-20 minutes to form a fiber-clay mixture;

[0025] Step 4: Add adhesive: Add white latex and stir at 100-200 rpm for 10-15 minutes until fully uniform;

[0026] Step 5: Pressing: Pour the material into the mold and press at a pressure of 10-15 MPa for 3-5 minutes to form a green body with a thickness of ≤5 mm;

[0027] Step 6: Gradient drying: First dry in 40-60℃ hot air circulation for 8-12 hours, then dry naturally in the shade for 3-5 days;

[0028] Step 7: Art board shaping: After air drying, the art board undergoes surface treatment and is finely ground with sandpaper to retain the natural crack texture.

[0029] Optionally, the natural shade drying conditions in step 6 are:

[0030] Ambient temperature 25°C, relative humidity 50%-60%;

[0031] When the green body is dried to a moisture content of 15%-20%, a needle is used to scratch the surface to guide the direction of the cracks, forming controllable micro cracks with a width of 0.1-0.3mm.

[0032] Compared with the prior art, the present invention has the following beneficial technical effects:

[0033] The invention uses sugarcane bagasse waste and natural clay as the main raw materials to achieve high-value utilization of agricultural waste, reduce incineration pollution, and use low-pollution white latex to reduce carbon emissions and chemical pollution from the source, which is in line with the low-carbon and environmental protection concept.

[0034] The raw material ratio and particle size are precisely controlled. Bagasse is crushed to 0.5-2mm, and clay particle size is ≤0.075mm with a purity ≥90%, ensuring a dense and stable board structure. By adjusting the volume ratio of bagasse to clay and the weight ratio of white latex to water, different properties such as lightweight and breathable or high strength can be achieved to meet diverse application needs.

[0035] Natural shade drying is used to form controllable micro-cracks of 0.1-0.3mm, and the texture is enhanced by adding quartz sand, giving the board a unique artistic expression; linen is applied to the back to increase the flexural strength by over 200%, balancing aesthetics and durability; the gradient drying and segmented firing process effectively controls cracks and internal structure, making the board's water absorption rate ≤10% and the air permeability index ≥500g / (㎡·24h), improving moisture-proof and breathable performance; precise control of parameters such as stirring speed, pressure, and temperature ensures product quality stability and consistency; a clear safety range of 15-28℃ temperature and 40%-65% RH humidity reduces the impact of environmental factors on board performance, reduces the risk of deformation and aging, and is applicable to a wide range of scenarios; supporting maintenance and repair solutions extend service life and reduce usage costs;

[0036] In summary, the present invention uses sugarcane bagasse and clay as core raw materials, which combines environmental protection and resource recycling value. Precise raw material ratio and particle size control achieve performance diversification, ensure that the board is widely used and durable, and promote green development in the field of art boards.
