Of the four key rubber technology innovation: 1819 Scottish chemist images and found that the rubber can be coal tar dissolved, then people began to dissolve the rubber with coal tar, turpentine, manufacturing tarpaulins. Elder brother, (in the UK in 1820 格拉斯哥) Set up. In order to make rubber products to facilitate processing. Hancock, 1826 ( Hancock) Developed with the method of mechanical give natural rubber plastic. 1839 americans Goodyear invented the rubber vulcanization method, and can solve the problem of raw rubber stiffen embrittling, make rubber with high elasticity and toughness, rubber truly entered the stage of industrial utility. Natural rubber, therefore, become the important industrial raw material, the silica gel products of rubber requirements have risen sharply. The development history of rubber: 11th century, people in South America had been using rubber ball games and offerings. In 1493 the Italian navigator Christopher Columbus sailing adventure to the americas, see Indian man with a black ball in play, the ball falls on the ground to play high, it is made from milk out of the tree. Since then, Spain and Portugal in the process of the conquest of Mexico and South America, the rubber knowledge gradually to Europe. The 18th century, France continuous send scientific expedition to South America. In 1736, French scientists condamine ( Charles de Condamine) Took part in the scientific expedition in South America, some from Peru rubber products and rubber in the record the relevant information back to France, published 'the South American mainland travel Henry'. The book details the origin of rubber tree, acquisition methods and utilization of the latex rubber pot and the process of the shoes has attracted people's attention. In 1768, the French mecca ( P。 J。 Macquer) Find available solvents softening rubber, medical supplies and the hose. In 1828, British troops piano and ( C。 麦金托什) Made from latex rain wear, but products, hot sticky cold crisp, very poor quality. In the 1880 s in the west in the process of the second industrial revolution, in 1888, a British doctor Deng Lupu ( 邓洛普) Invented the pneumatic tyre. In 1876 the British wickham, H。 一个。 韦翰) The rubber tree seeds and seedlings from Brazil to London's royal botanic gardens Kew ( 丘花园) Reproduction, and then cultivate rubber seedlings to Ceylon ( Now Sri Lanka) , Malaysia, Indonesia and other places to grow both success. Silicone rubber now also widely used in the automobile rubber parts. In 1887, Malaysia, Sri Lanka, Indonesia plant expanding based adhesive garden, RuiDe le, director of the Singapore botanic gardens ( H。 N。 Ridley) Invented the does not hurt rubber cambium tissue on the original cut mouth repeat cutting continuous tapping method, corrected the rubber tree with an axe of origin and hurt the tree, unsustainable production adhesive old method, can make the rubber tree decades continuous tapping. A new era of rubber market demand, with the consumption of rapid growth of silicone rubber industry has begun by the high performance special rubber into synthetic rubber, become one of the largest rubber varieties dosage. It is understood that from the consumption of analysing, natural rubber accounted for 41. 8%, styrene-butadiene rubber and butadiene rubber combined accounted for 28. 4%. With silicone rubber products, therefore, in the part of the niche of the tire to replace other analysing, its consumption will increase exponentially, will further open the market space. According to statistics, if by 2020 silicone rubber accounts for the proportion of rubber consumption in our country from the current six. 5% to 33%, so the overall domestic self-sufficiency rubber in China but from the current rise about 50% to 80%, thus greatly relieve the strain on rubber supply condition, reduce the production cost of rubber processing industry. Therefore, the development of silicone rubber industry is not only the single development of a single industry, but involves more than the common development of the industry, to enhance the profitability of the rubber processing industry and improve the quality of rubber products has far-reaching significance.
