Abstract
The upright cap is produced with the material compounded with rubber as main component, and rubber-reinforcing agent, antiager, vulcanizer, rubber promoter, rubber vulcanization activator and rubber plasticizer as supplements. Compared with metal one, the said upright cap has greatly lowered cost, and its outer chamfers make it easy to assemble and hard to separate. It has long service life due to its excellent ageing property and mechanical property.
Description
The present invention relates to a kind of rubber, rubber and plastic product, relate in particular to a kind of high speed highway guardrail upright post rubber, rubber and plastic cap that utilizes rubber, rubber-plastics material to replace metal and plastics-production to make.
Along with the development of transport service, the popularizing of automobile, speedway has also obtained development at full speed, and it provides transport pathway more fast, easily to people, plays important effect in whole national economy.Because the automobile driving speed on the speedway is fast, generally do not allow Xrds midway, for safety all adopt totally enclosed type, promptly be with protective guard in the speedway both sides, protective guard is made up of certain distance metallic steel tube column and steel plate at interval, its column is a cylindrical shape, and the column bottom is buried under the ground, and top is arranged in the speedway both sides, for preventing ponding etch roadbed and column casing in the stud cylinder, column matter end all is furnished with cap, can rain cover enter in the tube, seems attractive in appearance again.The material that is used to make the column cap at present has two classes usually, one class is a metal iron sheet cap, and another kind of is the plastics caps, and metal cap cost is higher, install inconvenient, though plastics cap cost is low, because fragility is big, so be difficult for being put into when especially the column installation of distortion being arranged when mounted for the top, if installing reluctantly, extruding cause cap broken and scrap easily, and need coating adhesive for preventing to come off when installing, very trouble is also stolen by some lawless persons easily.
It is lower to the purpose of this invention is to provide a kind of cost, good springiness, long service life, be easy to install and be difficult to be pulled out be exclusively used in rubber and plastic cap for guard fence upright of expressway.
Technology Fang An of the present invention is achieved in that a kind of rubber and plastic cap for guard fence upright of expressway that is exclusively used in, and main material is a rubber, and auxiliary material is rubber reinforcing filler, age resistor, vulcanizing agent.
Main material can also comprise plastics, and auxiliary material comprises rubber accelerator, vulcanization of rubber activating agent, rubber plastizing agent.
Its consumption is: rubber 20-100 part, reinforcing agent 20-120 part, age resistor 1-1.5 part, vulcanizing activator 0.5-10 part, accelerator 0.5-5 part, vulcanizing agent 0.5-10 part, plastics 10-30 part, plasticizing agent 0.5-12 part.
Rubber comprises natural rubber, neoprene, butadiene-styrene rubber, butyl rubber, EP rubbers, reclaimed rubber, active colloidal powder, elects neoprene, reclaimed rubber, active colloidal powder especially as.
Plastics comprise polyethylene, poly-second propylene.
Accelerator comprises altax, accelerator TT, captax, accelerant CZ, accelerant N A22.
Vulcanizing activator comprises stearic acid, zinc oxide, magnesia.
Age resistor comprises antioxidant D, antioxidant 4010.
Reinforcing agent comprises carbon black, calcium carbonate, potter's clay, SR super reinforcing agent SR.
Plasticizing agent comprises machine oil, paraffin, resin, pine tar.
Its preparation technology is: with above-mentioned prescription under 40 ℃-50 ℃ through mixing 50 minutes slices of glue pressing machine, the dress mould, then the sulfuration built-in temperature be 145-150 ℃ down sulfuration can go out product in 8-10 minute.
Good effect of the present invention is:
1, traditional speedway protective guard cap raw material is replaced, adopted cheap elastomeric material to add filler and make product cost reduce greatly.
2, because the elastomeric material good springiness is designed to the chamfering form so can pack into the outside of part in the stud cylinder in the bottom of product, both installed easily, be difficult to again extract, prevented from effectively to destroy and larceny.
3, product is ageing-resistant, long service life.After testing, its aging coefficient is 0.85, and brittleness temperature is-35 ℃, and hardness is 60-80, and breaking tenacity is the 50-110 kilograms per centimeter.
The invention will be further described below in conjunction with drawings and Examples:
Accompanying drawing is a main sectional structure schematic diagram of the present invention.
Can be found out that by accompanying drawing this cap top crown 1 is a dome, lower headgear 2 is the cylinder cylindricality, and crown and skullcap are cast as one, and at the skullcap outer surface chamfering 3 are arranged. Owing to the effect of chamfering so that skullcap is packed into easily is difficult in the stud cylinder pull out draw.
