Vietnam produces fireproof and bulletproof paint made from rice husks

A domestic company has successfully produced fireproof and bulletproof paint made from rice husks at a price only one-third of the price of foreign fireproof paint.

On January 10, the Workshop on paint application materials in fire prevention, held in Vung Tau City, received the attention of many construction companies and agencies related to the field of fire prevention and fighting (PCCC).

At the workshop, a nano fireproof paint made from rice husks was announced. This is the first water-based fireproof paint in the world using nano technology from rice husks, successfully produced by a Vietnamese paint company. This paint can be applied to many materials such as wood, concrete, plaster, and iron.

The workshop also conducted experiments, burning samples of materials coated with rice husk nano fireproof paint. The test results showed that the fire protection efficiency reached approximately 360 minutes, surpassing level 1, the highest level prescribed by Vietnamese technical standards.

Experimental burning of nano fireproof paint material made from rice husk at more than 1,000 degrees Celsius. When exposed to fire, the paint will swell to create a heat-resistant surface, isolating the fire from the material surface.

This is the invention of Associate Professor, Dr. Nguyen Thi Hoe, who received the Kovalevskaya Science Award from Russia. The technology of producing paint from rice husks has been patented in the US. Ms. Hoe said that there are many types of fireproof paint on the market, but they only slow down the fire at a temperature of 500-600 degrees Celsius, with prices up to 200,000 VND/m2. Meanwhile, foreign fireproof paints cost 50-100 USD/m2.

Ms. Hoe said that the paint she created can resist fire at temperatures of 800-1200 degrees Celsius, and when burned does not produce toxic gases. Tests have shown that the paint quality is superior to similar products from foreign countries such as Singapore, especially Germany, a country that is leading in fire-resistant paint technology in the world.

Regarding the selling price, Mr. Nguyen Khoi, Technical Director of Kova Paint Company, said that the price of paint is only 1/3 compared to imported fireproof paints. However, this price is still high, partly due to the high cost of transporting rice husks to the factory.

Burning 12 tons of rice husks only yields 1 ton of ash, which is further processed by new technology machines and can be applied to paint. However, the coverage of rice husk nano paint is quite good, on average 1 kg of paint can cover 1.5 m2 of material surface.

Mr. Tran Trung Thanh, Deputy Director of the Fire Prevention and Rescue Department, said that there are many types of fireproof paint on the market, but nano-material fireproof paint is the first to appear in Vietnam.

On-site experiments show that the fire resistance time of this paint is longer. The production of rice husk nano paint also takes advantage of rice husk, a waste product in agricultural production, contributing to creating additional income for farmers.

Many construction and interior design companies are quite interested in this new type of paint. Mr. Hoang Tien Lap, representative of Hoang Phu Investment, Production and Trading Joint Stock Company, said that the successful production of high-quality nano fireproof paint domestically contributes to reducing construction costs and saving time waiting for imports from abroad.

In addition to fireproof paint, Associate Professor, Dr. Nguyen Thi Hoe has successfully researched bulletproof paint, self-cleaning paint, and antibacterial paint. Bulletproof paint has been tested with live bullets in Cambodia, but has not been commercialized.
