Abstract
The invention relates to a plastic traffic barrier, which is characterized by being prepared from the following materials in part by mass: 60 to 80 parts of natural rubber or synthetic rubber, 10 to 40 parts of waste ethylene vinyl acetate (EVA) material, 1.5 to 2.5 parts of vulcanizer, 2.5 to 4.5 parts of accelerator, 1.5 to 2.5 parts of active agent, 1 to 2 parts of tackifier, namely RX-80 resin, 20 to 40 parts of filler, 5 to 10 parts of softening agent and 1 to 3 parts of coloring agent. The prepared plastic traffic barrier is attractive and safe, high in strength and low in cost.
Description
Technical field
The present invention relates to a kind of plastic cement traffic guardrail and preparation method thereof.
Background technology
Traffic guardrail can be divided into central isolation guardrail, motor vehicle and bicycle guardrail, People's Bank of China's guardrail, Green protection fence etc., and it mainly plays safety precaution and beauty function.Press the material branch, can be divided into Cement guard bar, steel pipe guardrail, cast iron guardrail, plastic guardrail, soak and mould guardrail and stainless steel guardrail etc.Some cities are usually because Cement guard bar, steel pipe guardrail, cast iron guardrail have been adopted in the restriction of economy and condition, but owing to lack detailing, aesthetic property is very poor, and the effect of guardrail is brought into play relatively poorly, has also influenced urban environment; Some city is put undue emphasis on ornamental, and has ignored guardrail inherent " safety " function: adopt the stainless steel guardrail like some city, but do not pay attention to the optical design of guardrail, the stainless steel guardrail brings light pollution on the contrary, causes to dazzle the eyes, and has influenced security; Like plastic guardrail, intensity difference, manual just can the dismounting of manpower separated connecting portion, and be fragile, performs practically no function; Mould guardrail and soak, though had safety and advantage attractive in appearance, its complex manufacturing technology concurrently; Cost is high, and owing to weld in the guards making process is many, bottom does not carry out anticorrosion surface treatment; After the surface was soaked and moulded processing, antiseptic power was low, be prone to get rusty, work-ing life is short.
Summary of the invention
One of the object of the invention is to overcome above-mentioned deficiency, provides a kind of and has concurrently attractive in appearance and safety, and intensity is high, the plastic cement traffic guardrail that cost is low.
Two of the object of the invention is to provide a kind of preparation method of plastic cement traffic guardrail.
The objective of the invention is to realize like this:
A kind of plastic cement traffic guardrail, said plastic cement traffic guardrail is formed by following each mass parts material prepn:
Tree elastomer or viton 60-80 part
Useless EVA material 20-40 part
Vulcanizing agent 1.5-2.5 part
Promotor 2.5-4.5 part
Promoting agent 1.5-2.5 part
Tackifier RX-80 resin 1-2 part
Weighting agent 20-40 part
Tenderizer 5-10 part
Tinting material 1-3 part.
Said vulcanizing agent is a sulphur, and said tenderizer is a machinery oil.
Said promotor is M, DM and TT.
Said useless EVA material is scrap stock such as EVA foaming shoe material.
A kind of preparation method of plastic cement traffic guardrail, said preparation method are that said preparation method comprises the steps: with above-mentioned each component machine-shaping
In the mill with tree elastomer or viton mastication under 30-40 ℃ of temperature, park more than 24 hours after mastication is good;
Giving up the EVA material in the mill after mastication under the 60-80 ℃ of temperature is good, fully mixing with tree elastomer that has parked or viton through mastication, add tackifier then and make its bag roller; Add 1/3 weighting agent then, add promotor again, behind the mixing, add the weighting agent of residue 2/3 and whole tenderizers, add promoting agent, vulcanizing agent and tinting material at last, process rubber unvulcanizate;
Said rubber unvulcanizate is processed plastic cement traffic guardrail finished product after vulcanizing, removing slitter edge.
The mastication temperature of said useless EVA material is 70 ℃.
The invention has the beneficial effects as follows:
In traditional cognitive domain, the characteristics of EVA material are that material is light, hardness is low, have good snappiness.Plastic cement traffic guardrail of the present invention; Broken through traditional EVA material cognition that hardness is low, snappiness is good, the EVA that will give up material is used for the plastic cement traffic guardrail, improves tree elastomer or elastomeric hardness; Use tackifier and tenderizer that the compatibility performance of the two is provided simultaneously; The shore hardness of the finished product that make reaches more than 90 degree, and intensity is high, is difficult for broken, easy fracture not in the collision process.
Adopt scrap stock such as depleted EVA foaming shoe material, when reducing production costs, accomplish the recycling of refuse, environmental protection.
In the course of processing, directly the pore that the micropore in the EVA foamed shoe body scrap stock forms is extruded, reached closely knit effect, need not pulverize through the technology of mastication, convenient and swift, and cost is low, it is little to pollute.
In the course of processing, through the setting of order of addition(of ingredients), make it improve its processing characteristics, and the product hardness of processing is high, quality is good.
