Liu Zhicheng, a citizen of Lianzhou with the reputation of "Lianzhou Edison", once again innovated his invention: After 5 years of research and development, he finally developed the "Liu's non-brominated general environmentally friendly flame retardant", which achieved a low price and excellent resistance. Combustion performance, ultra-low moisture absorption, no peculiar smell, non-toxic, green, low-carbon and environmentally friendly. Once patented, it will surely occupy an important place in the field of flame retardants.
"But the most worrying thing at the moment is that because of the convenient source of raw materials and low cost, it will be easy to be copied once it is launched. With my current strength, the difficulty of defending rights is too high." For this reason, Liu Zhicheng temporarily postponed the flame retardant. He hopes to negotiate and cooperate with powerful companies to ensure that his research and inventions are properly protected and put into production as soon as possible to benefit the society.
Sponges and paper towels that "cannot burn"
On December 14, the reporter saw at Liu Zhicheng’s house that only a colorless and odorless liquid was sprayed on. The extremely flammable tissues and sponges would not catch fire no matter how burned, at most after burning for a period of time. It just became scorched.
"Although some of the specific parameters of flame retardants have not been tested, the effect of flame retardant is obvious and very significant." Liu Zhicheng introduced that he had developed liquid flame retardants two years ago, but in order to let himself The products developed can be used in a wider range of materials. Since then, he has invested a lot of energy to successfully develop a solid flame-retardant powder, which will be fully improved this year.
In recent years, with the continuous development of science and technology, the field of materials has also emerged as a new force. Various new materials have been extremely widely used in construction and decoration, furniture manufacturing, chemicals and machinery, military facilities, and transportation. New materials have unique advantages, but many materials also have serious fire hazards. The main reason is that quite a few materials have not undergone the corresponding flame-retardant treatment and are extremely flammable.
Liu Zhicheng introduced that as a material for cushioning or heat insulation, sound absorption and sound insulation, it is widely used in sofas, mattresses, sponges and foams in the manufacture of seats for airplanes, trains, cars, etc. It is a typical representative of serious fire hazards. "Sponge and foam have a fast burning rate and high heat due to their loose porous or microporous structure, which not only brings great difficulties to the fire fighting operation, but also decomposes and releases a large amount of toxic effects to the human body during combustion. Containing sulfur oxides and high polymer smoke, causing secondary disasters."
At about 23:00 on September 20, 2008, a fire broke out in a club in Shenzhen. Although the fire department tried its best to put out the fire and the fire was quickly extinguished, the accident still caused 43 deaths and 88 injuries, of which 51 required hospitalization. It is understood that the fire was caused by the firework bombs being set off during the stage performances in the club’s performing arts hall. Sparks from the explosion of the firework bombs ignited the sound-absorbing sponge (polyurethane foam) on the ceiling and spread to disaster.
"I saw this report in the media, and I felt distressed. After searching a lot of information, I decided to develop a cheap, environmentally friendly and easy to promote flame retardant." Liu Zhicheng said.



The cost is only one-tenth of similar foreign products
In fact, if the cost is reasonable and environmentally friendly, I believe many people are willing to use flame retardant materials.
It is understood that in order to avoid major fires, developed countries often add flame retardants when producing flammable materials. When attacked by external fire sources, they can effectively prevent, delay or stop the spread of flames, so as to prevent fires. effect. However, some domestic manufacturers of polyurethane rigid foam, soft foam insulation, sound-absorbing materials and polystyrene, due to the consideration of production cost and market price competitiveness, most of them do not use imported flame retardants in the production process. At present, domestic manufacturers of flame retardants have not been able to produce flame retardants acceptable to manufacturers.
"Because of the high price of imported flame retardants, the current international market price is between 38,000 yuan and 70,000 yuan (RMB) per ton. If imported flame retardants are used, the product price will be too high to open the market." Liu Zhicheng said, not only that. , Brominated flame retardants, which hav
