Description
Technical field
The present invention relates to composite of water-proof coiled material field, and in particular to waste-tyre rubber-powder doping butyl rubber composite water-proof volume
Material.
Background technology
Junked tire main chemical compositions are natural rubber and synthetic rubber, also containing many other materials, as styrene,
Butadiene, butyl, different oxygen polybutadiene, glass fibre, polyester, zinc oxide, stearic acid, sulphur, metal, pigment, carbon black etc..
They are recycling resources, and there is tyre rebuilding enterprise about 500 in China at present, overhaul old tire more than 400 ten thousand year, regeneration
Family more than 500 of glue enterprise, produce nearly 400,000 t of reclaimed rubber per year, junked tire produces nearly 60 of the enterprise of rubber powder, produces rubber powder per year less than 50,000
T, using junked tire about 2,600 ten thousand -3,000 ten thousand, substantial amounts of rubber sources is saved.
The recycling of junked tire includes carrying out damaged tire the processing of restoration, is allowed to recover the renovation wheel of original purposes
Tire and prototype directly utilize.Regeneration is that damaged tire is made into reclaimed rubber or rubber powder.Heat utilization divides pyrolytic and directly pulls out combustion
Two classes are burnt, pyrolytic is to obtain miscella, pyrolysis gas and carbon black etc., Duo Zhonggan by hot cracked under damaged tire catalyst action
Analyte is evaporated, directly burning is to connect damaged tire as fuel to be used.
It is the up-and-coming mode that integrates ring and resource reutilization with junked tire is received by producing rubber powder, this
And reclaimed rubber production is abandoned by developed country, junked tire is turned into rubber powder by reclaimed rubber using emphasis and opens up other using neck
The main reason for domain, manufacture rubber powder, which is expected to the in a row the third-largest approach after renovation, heat energy utilization, the production technology of rubber powder, to be had
Normal temperature crushing up, cryogenic freezing comminuting method, water slug method etc..
The content of the invention
For prior art, the invention aims to provide waste-tyre rubber-powder doping butyl rubber composite water-proof volume
Material, the waterproof roll water resistance is good, brittleness temperature is low, flowing temperature is high, waterproof roll good weatherability, and low temperature, which is not likely to produce, to be split
Line, service life are longer.
In order to solve the above technical problems, the present invention provides waste-tyre rubber-powder doping butyl rubber composite of water-proof coiled material, institute
Stating waterproof roll includes the raw material of following parts by weight：70 ~ 90 parts of butyl rubber, 50 ~ 60 parts of reinforcing agent, 5 ~ 8 parts of rubber powder, rubber are soft
15 ~ 25 parts of agent, 35 ~ 50 parts of filler, 15 ~ 25 parts of fire retardant, 5 ~ 10 parts of coupling agent, 2 ~ 3 parts of organic active zinc, age resistor 2 ~
3 parts, 3 ~ 5 parts of accelerator, 2 ~ 4 parts of stearic acid, 0.5 ~ 1 part of antioxidant；
The rubber powder is fine vulcanized rubber powder prepared by junked tire, and its granularity is 60 ~ 80 mesh；

Vulcanization fine glue powder prepared by junked tire is added to waterproof roll, can improve water resistance, the drop of waterproof roll
Low brittleness temperature, enhancing flowing temperature, penetrability is reduced, make waterproof roll weatherability more preferable, caused crackle is few, service life
It is longer.The carbon black in junked tire and various additives can be made to be fully used simultaneously.
The RX includes the one or more in hydrogenated rosin, black factice, tall oil.RX one
As use petroleum-type softening agent, its bating effect is good, and ageing-resistant resistance to flexion, but petroleum-type softening agent contains more cyclophanes mostly
The poisonous and harmful substances such as hydrocarbon, heavy metal, amine, benzene class, are unfavorable for environmental protection.Hydrogenated rosin, and can to rubber softening significant effect
To increase the tack of sizing material, improve moulding process operation, while can also overcome plant softening agent to reduce sizing material resistance to ag(e)ing, resistance to
The problems such as cracking, fragility.Black factice can significantly improve the processing performance of sizing material, make that semi-finished product shrinkage factor is low, surface is smooth,
It is easy to be stripped during vulcanization, sulfur blooming, thickness coiled material hair engaging aperture phenomenon can also be reduced, and it is preferably resistance to be worth ear nail vulcanizate to have
Ozone, the effect of resistance to day light aging.Tall oil is a kind of liquid resin, and main component is aliphatic acid, resin acid and unsaponifiable matter,
It is preferable to rubber softening effect, it is easily dispersed filler, and cost is cheap.
