Description
Technical field
The invention belongs to freeway guardrail field more particularly to a kind of freeway guardrail composite materials.
Background technique
Freeway guardrail generally refer in highway two sides or median strip with road is disposed in parallel blocks
Facility, main function are that improper fleet vehicles caused by preventing faulty driver or other reasons run off highway or pass through center
The traffic accident that dividing strip swarms into opposite lane occurs, occupant safety on protection trackside pedestrian, building, driver and Che,
It has induction pilot's line of vision concurrently simultaneously, increase traffic safety sense and beautifies the effect of highway environment.With China's highway
The steel using amount of fast development, freeway guardrail is growing day by day.The output of steel in China is always maintained at 100,000,000 tons or more in recent years, entirely
The iron and steel resource of state is nervous.Environmental pollution when in order to keep the long-term sustainable development of mineral resources and reduce steel-making, it is necessary to effectively
Control steel-making yield.Therefore it should practice every conceivable frugality in every profession and trade using steel, rationally utilize iron and steel resource, while selecting other materials
Material replaces steel.
Freeway guardrail generally uses metal material bending and molding at present, it is that one kind is mutually spliced with ripple steel guard rail
And the continuous structure supported by main pillar.It, can since waveform steel guard rail plate has good crash-worthiness to act on when vehicle collides it
To effectively prevent smashing, spark can be especially generated during collision and causes car crash, most of traffic accident be by
Caused by expressway barrier is smashed.Existing freeway guardrail is unlikely to deform, and bending strength effect is undesirable.Cause
This it is necessary to improve the mechanical property of freeway guardrail on the basis of not increasing cost.
Summary of the invention
The defect that it is an object of the invention to overcome prior art freeway guardrail bending strength effect undesirable, provides
A kind of freeway guardrail composite material.
A kind of freeway guardrail composite material, the component including following parts by weight: 60-100 parts of resin, infrared ray absorbing

Kind or more mixture.
Specifically, the grammes per square metre of the basalt fiber cloth is 30g/m2、40g/m2Or 60g/m2One of grammes per square metre or two
Kind or more mixture.
In addition, including the following steps: the present invention also provides a kind of preparation method of freeway guardrail composite material
(1) prepare high-strength composite material: sequentially added into stirred tank resin, curing agent, infrared absorbent, filler,
Ultraviolet absorbing agent is transferred in glue groove after stirring；
(2) impregnation: being arranged in Multiaxial Fiberglass Fabrics and basalt fibre on warp thread plate, and warp thread plate is put into glue groove leaching
Glue；
(3) material after impregnation is then sequentially sent to preforming tool and molding die；
(4) curing molding at a temperature of 110 DEG C -180 DEG C draws depanning.
Beneficial effects of the present invention: (1) due in of the invention composite material containing Multiaxial Fiberglass Fabrics, so that this
The freeway guardrail composite material of invention has higher tensile strength, bending strength and impact flexibility, and when shock is unlikely to deform,
Bending strength effect is ideal, once car body, which is hit, has buffer function, greatly reduces the injury to the person, can satisfy open air makes
With safety；(2) composite material quality of the invention is relatively light, convenient in carrying；(3) weatherability of the invention is preferable.Due to the present invention
Composite material in contain infrared absorbent and ultraviolet absorbing agent, in the common of infrared absorbent and ultraviolet absorbing agent
Under effect, the temperature of composite material can be effectively reduced, shield infrared, ultraviolet light radiation.Specifically, infrared in summer
Light absorbers can shield most infrared rays in sunlight, and ultraviolet absorbing agent can shield exhausted most in sunlight
Number ultraviolet light, so that composite material has good barrier action to infrared ray, the ultraviolet light in strong sunlight.In addition, red
The performance of ultraviolet absorbers and ultraviolet absorbing agent makes composite material have excellent thermal insulation property.It in winter again can be effectively
The radiation for obstructing infrared ray, ultraviolet light, preventing composite material, outwardly air conducts heat, and prevents composite material from cracking, thus
Extend the service life of composite material；(4) present invention uses green material basalt fiber cloth, which is by single profound
Wire drawing obtains after military rock and ore melts at high temperature, and product and production process are nontoxic, is real green product,
Compared with steel type freeway guardrail, the usage amount of steel is greatly reduced, resource has been saved, is reduced environmental pollution, is met
Scientific development concepts；Abundant, the low in raw material price additionally, due to China's basalt ore, therefore it is compound to greatly reduce the present invention
The production cost of material has great Social benefit and economic benefit.
