Description
Technical field
The present invention relates to technical field of rubber material, more particularly, to a kind of high strength heat resistant nanometer silicon rubber and its preparation side
Method.
Background technology
The manufacturer of silicon rubber typically has dozens of or even the up to a hundred kind trades mark, is according to product characteristics and use mostly
Way is numbered, and also has and is classified according to vulcanization and chemical constitution.According to curing temperature, silicon rubber can be divided into high temperature vulcanized
Silicon rubber and room temperature vulcanized silicone rubber.One pack system, two-component room-temperature-vulcanized silicone rubber then can be divided into from packaged form.According to
The degree of polymerization, silicon rubber is further divided into mixed milling type silicon rubber and liquid silastic.
2006, six three councils of Chinese rubber TIA passed through discussion and issue《Chinese rubber industry " 11
Five " scientific development planning》And rubber industry Eleventh Five-Year Plan enforcement famous brand strategy planning.This is first by association and organization
The sector planning worked out.Planning shows, rubber industry the Eleventh Five-Year Plan period Independent Innovation to be walked, and the whole industry will proceed to conscientiously

2011, jumbo fluctuation in the prices of raw materials such as rubber, and the natural rubber first quarter creates 43500 yuan/ton go through
History highest record, have an effect synthetic rubber two, the third quater on attack, amount of increase reaches 10000 yuan/ton, all occurs afterwards plummeting.It is subject to
Rubber price big ups and downs affect, and the main rubber enterprise such as tire stands in the breach, and costs of production and operation is difficult to control to, stock
Increased risk, profit margin is compressed to 2%-5%, and industry faces a severe challenge.
Silicon rubber forms main chain by silicon, oxygen atom, and side chain is carbon-containing group, and consumption maximum is the silicon rubber that side chain is ethene
Glue.Both heat-resisting, resist cold, using temperature between 100-300 DEG C, it has excellent against weather and ozone resistance with good again
Good insulating properties.Shortcoming is low intensity, and tear resistance is poor, and anti-wear performance is also poor.Silicon rubber is mainly used in aircraft industry, electrically
The aspects such as industry, food industry and health care industry.
That is just more for big and small rubber required for industrial department, and wide in variety, purposes is wide, and have also has spy
Different requirement.Main product has adhesive tape, sebific duct, seal washer, rubber roll, offset plate, rubber lining and articles for labour protection.In ore deposit
The industrial aspect application adhesive tape such as mountain, coal, metallurgy transporting finished product, various places all continuously emerging, in order to large-scale production clouds will,
Also produce Steel cord conveyer belt and synthetic fibers conveyer belt.Mining grinding mill rubber lining, replaces manganese steel to forge glue, using the longevity
Life improves two to four times, also reduces noise, this product is worldwide promoted.
