Description
Technical field
The present invention relates to a kind of giant tyre refreshing appliance technical field, relate in particular to a kind of giant tyre retreading vulcanizing equipment.
Background technology
Natural rubber has become China's another large strategic goods and materials in short supply after the raw materials of industry such as oil, iron ore and non-ferrous metal at present.China's rubber-consumer amount occupied the first in the world continuously from 2002, and it is nearly 20% to account for world's rubber-consumer amount, and wherein nearly seventy percent natural gum need rely on import.The annual rubber that consumes 70% of China is used for making tire, and every year is with nearly 15% speed increase.In China rubber sources situation in short supply, more need actively develop the junked tire cycling and reutilization, not only economize on resources but also can reduce pollution, can also create considerable economic benefit.Tyre retreading is the recycling first-selection of tire, has become the second source of tire.Giant-scale engineering tyre is because environment for use is more abominable, and wearing and tearing and machine are hindered serious, have accelerated the speed of scrapping of tire, within 1 year even will change tire 2-3 time, if all use new tyre, the price of a new tyre just reaches about 300,000 yuan, and the tire cost will be quite high.Domestic 1 57 at present " more than 30 ten thousand yuan/bar of the domestic price of mining and logging tyre, renovate 1 price and only be equivalent to new tyre price 30-40%, greatly reduce the tire used cost.Engineering tyre renovation ratio constantly increases in recent years, super large and giant tyre renovation ratio even reach the degree of 60%-80% abroad, and China's utilization rate is less than 20%, has not only wasted a large amount of waste and old engineering tyre resources, has also increased the consuming cost of tire used.Preventing junked tire to environment, and it is carried out effective recycling, become China's sustained economic development problem needing to overcome, also is the requirement that rubber industry is developed a circular economy simultaneously.
At present in the giant tyre refurbishment process, sulfuration is vital flow process, and traditional giant embryo retreading vulcanizing adopts vulcanizer, with the tire of this technology renovation, because of tyre surface very thick, decorative pattern is very dark, and cure time is long, and energy consumption is excessive, be unfavorable for energy-saving and emission-reduction, and serious because of thermo-oxidative ageing, the wear-resisting and anti-thorn of tyre surface seriously reduces, and has shortened the service life of tire; The shortcomings such as existing vulcanizing tank directly belongs to low-temp low-pressure with steam or mist (steam+nitrogen) heating and vulcanizes for a long time in addition, causes the carcass thermo-oxidative ageing, and crown is surfaces of tacky all, and tyre retreading is of low quality.On tyre retreading technology, presulfurization method and modelling tyre retreading technology relative complex, and need to increase the expenses such as sealing shroud and mould.Although the simple cost of free vulcanization tyre retreading technique is low, also there is low problem in service life, be the 70%-80% in new tyre life-span only.The patent No. 201010585057.4,200980109796.1,201020103508.1 of for example announcing on the patent network, 200920124774.x and tire curing bladder Patents, mostly be the vulcanizing equipment of tire production process, can not satisfy the sulfuration requirement of engineering giant tyre.
