1763, the Frenchman Mecca invented a solvent that can soften rubber.
1888, an Englishman, Deng Lubian, invented pneumatic tires, and began to produce cars in 1895. The rise of automobile industry has aroused great demand for rubber, and the price of rubber has soared.
1897, Huang Dele, director of Singapore Botanical Garden, invented the continuous tapping method of rubber trees, which greatly increased the rubber output. Therefore, the wild rubber tree has become an important cash crop planted in a large area.
1493, the great Spanish explorer Columbus led a team to set foot on the South American continent for the first time. Here, Spaniards see Indian children and young people playing games, singing and throwing balls at each other. This kind of ball can bounce very high after landing, and it will feel sticky and smoky if it is held in your hand. The Spaniards also saw Indians coating some white sticky liquid on their clothes to protect them from rain in rainy days. You should also apply this white viscous liquid to your feet, so that it won't get wet in rainy days. As a result, the Spanish initially understood the elasticity and waterproofness of rubber, but did not really understand the source of rubber.
1693, French scientist Lacan arrived in South America and saw the aborigines playing with this kind of ball. Scientists and soldiers have different thinking and vision. Through the investigation of this small ball, they knew that this small ball was made of a viscous liquid from a tree called "rubber" by Indians.
1736, French scientist Kang Damin brought back detailed information about rubber trees from Peru, and published A Brief History of South America, which introduced the origin of rubber trees, the methods of collecting latex and the utilization of rubber in detail, which attracted people's attention.
1763, the Frenchman Mecca invented a solvent that can soften rubber.
1770, British chemist Priest Le discovered that rubber can erase pencil handwriting.
1823, Englishman MacIntosh, like the Indians, painted thick white rubber liquid on the cloth to make a tarpaulin and sewed a "MacIntosh" waterproof cloak, which may be the earliest raincoat in the world.
1852, American chemist guthrie accidentally dropped a jar containing rubber and sulfur on the fire while doing experiments. After heating, rubber and sulfur flow together to form a block rubber skin, thus inventing the rubber vulcanization method. Gu Deyi's accidental behavior is an important invention in rubber manufacturing industry, which removes a big obstacle for rubber application, makes rubber a formal industrial raw material from now on, and thus enables many rubber-related industries to flourish. Subsequently, guthrie made the world's first pair of rubber waterproof shoes with vulcanized rubber.
From 65438 to 0876, an Englishman named Wei narrowly escaped death. He collected 70,000 rubber seeds from the tropical jungle of the Amazon River, sent them to the Royal Autumn Botanical Garden in London, England for cultivation, and then transported the rubber seedlings to Singapore, Sri Lanka, Malaysia, India and West Asia for planting, and achieved success. By 2004, natural rubber/KLOC-0 has been successfully planted all over the world for 28 years.
1888, an Englishman, Deng Lubian, invented pneumatic tires, and began to produce cars in 1895. The rise of automobile industry has aroused great demand for rubber, and the price of rubber has soared.
1897, Huang Dele, director of Singapore Botanical Garden, invented the continuous tapping method of rubber trees, which greatly increased the rubber output. Therefore, the wild rubber tree has become an important cash crop planted in a large area.
1904, China A Dai Tusi Anren bought 8,000 rubber seedlings from Singapore and brought them back to China to plant them in Fenghuang Mountain, a new city in Yingjiang County, Yunnan Province at 24 north latitude. There is only one plant left.
1906- 1907, patriotic overseas Chinese in Qionghai, Hainan introduced 4,000 rubber seeds from Malaysia and planted them in Huixian (now qionghai city) and Danxian.
19 15 years, Dutchman Hutton invented the rubber budding method in Guawamau Botanical Garden, Indonesia, which enabled excellent rubber clones to be propagated and popularized in large quantities.
In 2003, the world output of natural rubber was 7,535,700 tons. The top five rubber producers in the world are Thailand, Indonesia, India, Malaysia and China, with a total rubber output of 6,292,500 tons, accounting for 83.5% of the global rubber output.
At the end of 1950s, Philips Company of the United States successfully developed solution polymerized styrene-butadiene rubber (SSBR) by anionic polymerization initiated by lithium, and it was industrialized in 1964. The industrial production of SSBR usually uses alkyl lithium, mainly using butyl lithium as initiator, alkanes or cycloalkanes as solvent, alcohols as terminator and tetrahydrofuran as randomizer. However, due to the poor processability of SSBR, its application has not developed rapidly. In the late 1970s, the demand for tires became higher and higher, and higher requirements were put forward for the structure and performance of rubber. In addition, the progress of polymerization technology makes SSBR develop rapidly.
In the early 1980s, Duniop Company in the UK and Shell Company in the Netherlands jointly developed a new SSBR product with low rolling resistance through polymer design technology. Dutch Shell Company and Lugongpu Tire Company jointly developed new SSBR products, and Japanese Synthetic Rubber Company and Bridgestone Company jointly developed new second-generation SSBR products such as tin-coupled SSBR, which marked that the production technology of SSBR entered a new stage.
SSBR developed relatively late in China. 1982 the research institute of Beijing Yanshan petrochemical company conducted a pilot study on the polymerization of styrene and butadiene in n-butyl lithium-tetrahydrofuran-cyclohexane system. 1984 carried out the amplification test, 1989 developed a new type of energy-saving SSBR, and 1kt industrial device was successfully developed. 1996 Beijing Yanshan petrochemical company successfully developed 10kt SSBR production line, and cooperated with relevant units to conduct application research in automobile tires, bicycle tires, rubber overshoes, sundries, modified asphalt, etc. The basic physical properties, processability evaluation and tire tread formula of SSBR were studied by Beijing Rubber Industry Research and Design Institute.
2 1 century rubber develops rapidly. The automobile industry has promoted the rubber industry, while the shortage of resources and environmental requirements have promoted the utilization of recycled rubber. Aerospace science and technology put forward newer and higher requirements for rubber.
