Description
Technical field
The utility model relates to a kind of steel tendon, specifically a kind of bridge stay cable.
Background technique
Basalt fibre: the glass fibre drawn with natural basalt.It is that basalt building stones are molten at 1450 DEG C~1500 DEG C
After melting, pass through continuous fiber made of platinum-rhodium alloy bushing high speed pulling.The color of pure natural basalt fibre is generally
Brown, some are like golden.Basalt fibre is a kind of novel inorganic environment-friendly and green high performance fibre material, it is by titanium dioxide
The oxides such as silicon, aluminium oxide, calcium oxide, magnesia, iron oxide and titanium dioxide composition basalt building stones after high-temperature fusion,
By made of bushing Defect.Not only intensity is high for basalt continuous fiber, but also has and be electrically insulated, is corrosion-resistant, resistance to height
A variety of excellent properties such as temperature.In addition, the production technology of basalt fibre determines that the waste of generation is few, environmental pollution is small,
And can directly degrade in the environment after product abandonment, it without any harm, thus is the qualified green of one kind, environment-friendly materials.
China is classified as basalt fibre in four given priority to big fiber (carbon fiber, aramid fiber, ultra-high molecular weight polyethylene, basalt
One of fiber), realize industrialized production.
Basalt fibre flameproof fabric is made at present, for example State Intellectual Property Office discloses Publication No.
CN105776878B, patentee are five source composite material Co., Ltds of Sichuan space flight, it is to file an application on September 2nd, 2015
, the invention discloses a kind of basalt fibre flameproof fabrics, are made after surface covering by basalt fiber cloth, the Black Warrior
Rock fiber cloth is woven after basalt fibre spun yarn is made in twisting using continuous basalt fiber precursor；The surface covering
The coating paste used includes following components: film forming agent 3~4.5%, lubricant 0.2~0.7%, antistatic agent 0.1~0.3%, idol
Join agent 0.2~0.7%.The basalt fibre flameproof fabric that the present invention is prepared not only has excellent low temperature resistant and heat-resisting quantity
Can, but also have many advantages, such as that low capacity, low thermally conductive, anti-thermal shock, resistant to chemical etching, tensile strength and elasticity modulus are high.
Currently, basalt fibre flameproof fabric on bridge stay cable there are no people's use, basalt fibre is used in decision
On bridge stay cable.
