Warmly celebrate our company's successful research and development of bio-based silica matting powder

Recently, Anhui Evolution Silicon Nanomaterials Technology Co., Ltd. received good news - the company's independently developed bio-based silica matting agent has been successfully launched. This product uses rice husk and carbon dioxide as core raw materials and achieves "waste-to-treasure" through innovative technology. It combines environmental protection attributes with excellent performance, providing a new solution for the green upgrading of the coatings and inks industries.

Innovative Raw Materials and Technological Breakthrough: From Agricultural Waste to High-Value-Added Materials

The bio-based silica matting agent developed this time uses rice husk (waste from rice processing) and industrially emitted carbon dioxide as raw materials in a groundbreaking way. It is synthesized through a special carbon dioxide acidification precipitation process and its performance is optimized through surface treatment. This technical approach not only solves the problem of rice husk resource utilization but also, through the "waste-to-treasure" of carbon dioxide, provides a sustainable paradigm for material production under the "dual carbon" goal.

Compared with traditional matting agent preparation processes, this technology has three major advantages:

1. Green raw materials: Rice husk is renewable, and carbon dioxide is utilized as a resource, reducing the carbon footprint from the source;

2. Refined process: Precise control of parameters such as particle size (D50 range 2.0~10μm) and specific surface area (180~250㎡/g) to meet the needs of different scenarios;

3. High purity and strong stability: Silica content ≥98.0%, outstanding chemical inertness in the coating system, does not affect storage and use performance.

Four Core Advantages Empower Multi-field Applications, Leading Performance Indicators in the Industry

1. Excellent matting efficiency, precise gloss control

The product can achieve precise adjustment of the gloss of the coating film through different particle size specifications (such as MA2230 to MA2290 series). The matting effect is uniform, especially suitable for wood coatings, industrial coatings, and other scenarios with high requirements for matte texture, avoiding the uneven gloss that may occur with traditional materials.

2. Excellent chemical stability, adaptable to complex systems

In complex formulations such as gravure inks and offset inks, the bio-based silica matting agent exhibits excellent acid and alkali resistance and compatibility, does not react with other components in the system, and ensures the stability of the product during storage and construction.

3. Wide particle size gradient coverage, strong process adaptability

The multi-specification particle size distribution from 2.0μm (MA2230) to 10μm (MA2290) allows it to be flexibly adapted to different processes such as high-speed roll coating of roll coatings and fine film formation of ink printing. For example, fine-particle products are suitable for the flatness requirements of thin coatings, while larger particles can enhance the matting effect of thick coatings.

4. Versatile Application Scenarios, Comprehensive Performance Upgrades

Currently, the product has achieved industrial application in the fields of wood, general industry, roll coatings, gravure inks, and offset inks:

1. In wood coatings, it can improve the matte texture and scratch resistance of the coating film;

2. In roll coatings, excellent dispersibility avoids defects such as fish eyes and pinholes in the coating, ensuring industrial production efficiency;

3. In the ink field, it can optimize the gloss of printed products to meet the needs of high-end scenarios such as packaging and printing.

Technical Indicators

It is worth noting that this product is a precipitation method C-type hydrophilic (CA type). Compared with traditional gel method products, it is more competitive in dispersion efficiency and cost control. At the same time, the whiteness ≥93% and iron content is extremely low, meeting the stringent requirements of the high-end market for material purity.

Deep Cultivation of Green Innovation, Promoting a New Paradigm for Industrial Upgrading

As an innovative enterprise in the field of nanomaterials, Evolution Silicon Nano's research and development breakthrough not only demonstrates the company's technological accumulation in the field of bio-based materials but also sets a benchmark for sustainable development for the traditional chemical industry with its "waste-to-treat-waste" model. Industry experts point out that the commercialization of this product will accelerate the transformation of the coatings and inks industries towards low VOC and high performance, and is expected to become an ideal substitute for traditional matting materials, especially in furniture, automobiles, packaging, and other fields with high requirements for environmental protection and appearance.

"The research and development of this bio-based silica matting agent is an important implementation of the company's 'green materials + innovative technology' strategy." Shen Jiafeng, general manager of Anhui Evolution Silicon Nanomaterials Technology Co., Ltd., said, "In the future, we will continue to develop more functional products based on bio-based raw materials, drive industrial upgrading through technological innovation, and contribute Chinese wisdom to the global development of green materials."
