On the historical origins of the silicone rubber and its development

Mar 02, 2017

Natural rubber industry research and applications began in the early 19th century.Majintuoxi 1819 Scottish chemist found that rubber can be coal tar solution, since then people began to dissolve the rubber with coal tar, turpentine and other, making waterproof cloth. Since then, the world's first rubber factory in England in 1820gelasi (GLASGOW) established. For ease of processing of rubber products in 1826, Hancock (Hancock) invented the mechanical ways to make access for natural rubber-plastic. 1839 American Goodyear invented vulcanization of rubber, and solve the problem of rubber adhesive brittle, has high elasticity and strength of rubber, rubber into industrial practice. Therefore, became an important industrial materialof natural rubber, rubber demand will also rise sharply.

As early as in the 11th century, people of South America have been using rubber balls in the game and a sacrifice. 1493 Italian Navigator Christopher Columbus's second voyage expedition to America, see the Indians play a black ball in hand, the ball dropped to the ground to play high, it is made from milk taken from the tree. Since then, the Spanish and Portuguese conquest of heixige and in South America, to rubber knowledge being brought to Europe.

Into the 18th century, the French sent a scientific expedition to South America in a row. 1736 French scientist, La Condamine (Charles de Condamine) participated in scientific expeditions in South America, from Peru, some rubber and record relevantinformation on rubber tree was brought back to France, published on the South American mainland of JI. The book detailing the origin of rubber trees, collect LaTeX and rubber makers and shoe, attracted people's attention.

In 1768, the French Mecca (P. J. Macquer) to find available solvents to soften the rubber, made of medical supplies and hoses. In 1828, MA tuoshi (C. Mackintosh) made using LaTeX waterproof cloth, but sticky products hot weather, cold crisp, quality is very poor.

In the 1880 of the 19th century during the second industrial revolution in the West,in 1888 the doctor Deng Lu Pu (Dunlop) invented the pneumatic tire. In 1876, H. a. Wickham from the Brazilian rubber tree seeds and seedlings shipped back to London's Royal Botanic Gardens Kew (Kew Garden) the breeding and cultivation of rubber seedlings shipped to Ceylon (now Sri Lanka), Malaya, Indonesiaand other places were successfully planted. Now silicone rubber is widely used in the automotive rubber parts.

In 1887, the planting to establish rubber plantations, Sri Lanka, Indonesia, Malaysia, Singapore Botanic Gardens Director Rui Delei (H. N. Ridley) invented not to hurtthe Cambium tissues of hevea brasiliensis in the original cut on repeated cutting method of continuous tapping, was correct origin of the axe to cut a tree down forgum injuries of hevea brasiliensis tree, not sustainable yield of old methods, the continuous tapping rubber trees for decades.

In recent years, silicone rubber industry has made remarkable achievements. Withthe leap-forward growth of consumption, silicone rubber industry has started to change from high performance rubber for bulk synthetic rubber, becoming one of the largest rubber products. It is reported that the rubber from rubber consumption situation, natural rubber, 41.8% rubber and butadiene rubber accounted for 28.4%. Therefore, replaced with silicone rubber in some segments of the non-tire rubber, its consumption will grow exponentially, will further open the market space.

In this regard, industry insiders agree with these views. It is expected that by 2015,10%~15% per cent of total domestic rubber consumption of silicone rubber, silicone rubber consumption is expected to reach 1 million ~150 million tons by 2020, silicone rubber is expected to reach 20%~33% per cent of total rubber consumption, namely, silicone rubber consumption is expected to reach 3 million ~500 milliontonnes. In other words, development potential and long-term development of silicone rubber industry are very attractive and its high-speed development also will have far-reaching impact on upstream and downstream industries. In fact, silicone rubber-industry linkage effects of upstream and downstream industries have begunto appear.

According to statistics, by 2020 silicone rubber as a proportion of China's rubberconsumption increased from 6.5% to 33%, then China's rubber's overall domesticself-sufficiency rate from its current level of approximately 50% to 80% above, which greatly ease the tight rubber supply situation, reduce production costs for rubber industry. It can be seen that single development of silicone rubber industry development not only of individual industries, but involves the common developmentof various industries, for the rubber processing industry's profitability and improve the quality of rubber products are of far-reaching significance.
