Abstract
The invention discloses a kind of scrap tire rubber regeneration technology, comprise the following steps：Scrap tire rubber is selected first, drained after cleaning, crushed again, then the rubber after crushed is placed in reactor, heating causes rubber softening, extruded by extrusion equipment, and equidistant segment is carried out according to demand, the rubber after segment is placed in cooling tower again and cooled down, rubber after cooling passes through pre-treating technology, then carries out compacting slice through the conche in moulding equipment, mill, is eventually fabricated reclaimed rubber finished product, the present invention turns waste into wealth, and reduces production cost.
Description
Technical field
The invention belongs to the technical field of rubber, specially a kind of scrap tire rubber regeneration technology.
Background technology
The extensive use of rubber product causes the accumulation of a large amount of waste and used rubber tyres, and this not only causes the wasting of resources, also makes
It is occupied to obtain the confined space, while serious pollution is also result in water resource, air etc..Method currently used for rubber regeneration
Mainly there are 3 kinds：Physics method of reproduction, chemical regeneration method, bio-regeneration method, physics regenerative process energy expenditure is big, and regeneration level is not
It is controlled；Chemical regeneration method usually needs HTHP, easily causes C-C to be broken, and destroys major key structure, makes the performance of reclaimed rubber
Decline, and environment can be polluted；Bio-regeneration method is a kind of gentle relative to physics method of reproduction and chemical regeneration method
Regeneration.
The content of the invention
It is an object of the invention to provide a kind of scrap tire rubber regeneration technology, reduces production cost.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of scrap tire rubber regeneration technology, comprises the following steps：Scrap tire rubber is selected first, after cleaning
Drain, then crushed, then the rubber after crushed is placed in reactor, heating causes rubber softening, is set by extrusion
It is standby to be extruded, and equidistant segment is carried out according to demand, then the rubber after segment is placed in cooling tower and cooled down, after cooling
Rubber pass through pre-treating technology, then carry out compacting slice through the conche in moulding equipment, mill, be eventually fabricated regeneration
Rubber product.
Further, the pre-treating technology comprises the following steps：First 2h, room temperature are soaked with the ethanol that concentration is 75%
Lower drying, is sterilized and detoxification treatment, then makees chain extender with allicin, and Tween 80 makees consisting of phase-transferring agent, and adds water mixing 2h,
Regeneration reactor is added, regenerates 30h, handles the waste tire rubber powder of detoxification.
Further, the temperature in the reactor is 450-500 DEG C, and the temperature in the extrusion equipment is 380-400
DEG C, in the cooling tower in temperature be 150-250 DEG C.
The beneficial effects of the invention are as follows：
To the recycling of waste tire rubber, resource, environmental protection are saved.
Embodiment
Embodiments of the invention are described in detail below, but what the present invention can be defined by the claims and cover
Multitude of different ways is implemented.
A kind of scrap tire rubber regeneration technology, comprises the following steps：Scrap tire rubber is selected first, after cleaning
Drain, then crushed, then the rubber after crushed is placed in reactor, heating causes rubber softening, is set by extrusion
It is standby to be extruded, and equidistant segment is carried out according to demand, then the rubber after segment is placed in cooling tower and cooled down, after cooling
Rubber pass through pre-treating technology, then carry out compacting slice through the conche in moulding equipment, mill, be eventually fabricated regeneration
Rubber product, the pre-treating technology comprise the following steps：2h is soaked with the ethanol that concentration is 75% first, is dried at room temperature,
Sterilized and detoxification treatment, then make chain extender with allicin, Tween 80 makees consisting of phase-transferring agent, and adds water mixing 2h, and addition is again
Raw reactor, 30h is regenerated, handle the waste tire rubber powder of detoxification, the temperature in the reactor is 450-500 DEG C, described
Temperature in extrusion equipment is 380-400 DEG C, in the cooling tower in temperature be 150-250 DEG C.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
Spirit and principle within the modifications, equivalent substitutions and improvements made etc., should be included in the claim protection model of the present invention
Within enclosing.
