The invention has good insulating performance and heat resistance, strengthens damping performance and cutting resistance of the rope, and has high safety, high-temperature resistance, soft and comfortable performance and wide application range.

Description

Carbon fiber and basalt fibre compound rope

Technical field

The present invention relates to a kind of netting, especially relate to a kind of carbon fiber and basalt fibre compound rope.

Background technology

Carbon fiber is the excellent new material of a kind of mechanical property, and its proportion is less than 1/4 of steel, and carbon fiber resin composite material tensile strength all more than 3500Mpa, is 7～9 times of steel generally; Tensile modulus of elasticity is that 23000～43000Mpa also is higher than steel; Density is little, and specific strength is that the ratio of intensity and its density of material can reach more than the 2000Mpa/ (g/cm3), and the specific strength of A3 steel is merely about 59Mpa/ (g/cm3); The quality of carbon fiber is 1/4 of a steel, is 1/2 of aluminium alloy, and specific strength is bigger 16 times than steel, and is bigger 12 times than aluminium alloy; The ability superhigh temperature resistant, carbon fiber can not melt under the high temperature of 3000 ℃ of nonoxidizing atmospheres 2000 ℃ of uses, and is softening; Resistance to low temperature is good, and under-180 ℃ of low temperature, it is more crisp than glass that iron and steel becomes, and carbon fiber is still very soft; Acid resistance is good, erosion medium resistance such as ability concentrated hydrochloric acid, phosphoric acid, sulfuric acid, benzene, acetone; Thermal coefficient of expansion is little, and thermal conductivity factor is big, also can not burst even drop to room temperature suddenly from 3000 ℃ high temperature.Because carbon fiber has excellent properties, can be processed into fabric, felt, seat, paper and other materials.Basalt fibre be with natural volcano effusive rock as raw material, its broken back is added in melting furnaces, after 1450 ℃～1500 ℃ fusions, the continuous fibers of processing through the platinum-rhodium alloy bushing.Basalt fibre has significant resistance to elevated temperatures and thermal shock resistance; The serviceability temperature scope is-260 ℃～880 ℃; This temperature is higher than aramid fiber, alkali-free E glass, asbestos, rock wool, stainless steel far away, near silica fibre, aluminium silicate fiber peacekeeping basalt fibre; Good thermal shock stability remains unchanged under 500 ℃ of temperature, and original weight only loses 3% in the time of 900 ℃.Have the lower coefficient of heat conduction, the coefficient of heat conduction is 0.031W/mK～0.038W/mK, is lower than aramid fiber, alumina silicate fibre, alkali-free glass fiber, rock wool, silica fibre, basalt fibre and stainless steel.Has high elastic modelling quantity and tensile strength; Elastic modelling quantity is: 9100kg/mm2～11000kg/mm2; Be higher than alkali-free glass fiber, asbestos, aramid fiber, polypropylene fiber and silica fibre; Tensile strength is 3800～4800MPa, and is all higher than big tow basalt fibre, aramid fiber, PBI fiber, steel fibre, boron fibre, alumina fibre, suitable with the S carbon fiber.Chemical stability is good, and acid resistance and alkali resistance are all good than aluminoborosilicate fiber, and its durability, weatherability, UV resistant irradiation, resistance to water, performance such as anti-oxidant all can be compared U.S.A with natural basalt stone.Sound-absorption coefficient is higher, and sound-absorption coefficient is 0.9～0.99, is higher than alkali-free glass fiber and silica fibre; Good wave and certain wave absorbtion, sound-absorbing and sound insulation value are excellent.Have excellent electric insulating and dielectric properties, specific volume resistance is higher to be 1 * 1012 Ω m, is much higher than alkali-free glass fiber and silica fibre; Specific insulation is than the high one magnitude of electric insulation E carbon fiber.Lower hygroscopicity, hygroscopicity is lower than 0.1%, is lower than aramid fiber, rock wool and asbestos.Escaping rope is the fire disaster escaping essential product, all has escaping rope in external many national families, and at home during fire rescue, fireman's ascend operation in fire fighting rescues the people or when saving oneself, escaping rope is the protective articles that must use.Normally used escaping rope is to be made by steel wire, and carbon current fiber and basalt fibre also are not applied on netting.

Summary of the invention

The objective of the invention is: improve a kind of good flame resistance, high temperature resistant, carbon fiber and basalt fibre compound rope that intensity is high, safe and reliable.

Technical scheme of the present invention is: be made up of rope sling and wire rope core; Rope sling is a tubular; Multi beam rope strand by carbon fiber and basalt fibre are formed is complete according to certain braid method braiding, and every binding yarn thigh is formed by many surface-treated carbon fibers and basalt fibre single twisting, and wire rope core is positioned in the middle of the rope sling; Wire rope core is the carbon fiber and the basalt fibre of boundling, and said carbon fiber monofilament and basalt fibre monofilament are 50%: 50% by mass percentage.

The invention has the beneficial effects as follows: because the multi beam rope strand that rope sling is made up of carbon fiber and basalt fibre is complete according to certain braid method braiding, the while wire rope core also adopts the carbon fiber and the basalt fibre of boundling, makes the intensity height of product; ABRASION RESISTANCE is good, and is high temperature resistant, has good insulation performance property and heat resistance; The damping and amortization and the cutting resistance that have strengthened rope can; Of the present invention safe, high temperature resistant, applied range; Except that being applied to the high building high altitude escape, can also be applied to fields such as construction.

Description of drawings

Fig. 1 is the structural representation of a kind of carbon fiber of the present invention and basalt fibre compound rope.

The specific embodiment

Can find out that from the structural representation of a kind of carbon fiber of the present invention shown in Figure 1 and basalt fibre compound rope the present invention is made up of rope sling 1 and wire rope core 2, rope sling 1 is a tubular; The multi beam rope strand of being made up of carbon fiber and basalt fibre is woven into according to certain braid method; Fig. 1 is a kind of specific embodiment of the present invention, is 32 sennits cover 1 and twisting wire rope core 2, can adopt two braid method processing complete; Also can adopt the processing of stereo weaving or other weaving manner; Combine closely between rope sling 1 and the wire rope core 2 in the middle of the rope sling, wire rope core is the carbon fiber and the basalt fibre of boundling, and carbon fiber monofilament and basalt fibre monofilament are 50%: 50% by mass percentage.Every bundle carbon fiber and basalt fibre are formed by many surface-treated carbon fibers and basalt fibre single twisting.Because the major defect of carbon fiber is that resistance to impact is relatively poor, oxidation takes place in damage easily under the strong acid effect, and carbon fiber carries out surface treatment before use.The major defect of basalt fibre is heavier, and resistance to impact is relatively poor, and basalt fibre also will carry out surface treatment before use.Through carbon fiber and the basalt fibre monofilament that the different surface treatment agent is handled, have advantages such as softness, suitable sliding, hydrophobic and shrinkage factor are low, remedied the deficiency of single fiber.Because rope sling of the present invention and wire rope core have adopted good flame resistance, high temperature resistant, carbon fiber and basalt fibre manufacturing that intensity is high; Adopted scientific and rational weaving manner again; Make product have good insulation performance property and heat resistance, strengthened the damping and amortization and the cutting resistance ability of rope, safe; Soft comfortable, applied range.
