Abstract
The invention relates to a manufacturing process of reclaimed reduction rubber and particularly relates to a manufacturing process of EPDM (Ethylene-Propylene-Diene Monomer) rubber through reduction and reclaim of waste rubber. The manufacturing process comprises the following steps: firstly, adjusting the roll spacing of an open mill to be zero, and the rotating speed of the open mill to be 40 revolutions per minute plasticizing colloidal particles and waste rubber rim charge for one time, and then adding matched raw materials for plasticizing for 10 minutes; then adjusting the roll spacing of the open mill to be 0.5mm, adding operation additives and a rubber compound to be mixed for 5 minutes, and then discharging slices at the temperature of 40-60 DEG C; after discharging the slices, carrying out vulcanization by using a vulcanizing machine so as to manufacture finished products. The manufacturing process can be used for reducing the production cost and improving the production efficiency and the product quality. Meanwhile, the manufacturing process meets the requirements on environmental protection in the 21st century, is in line with the economic mode of recyclable and sustainable development, and can be used for realizing environmentally-friendly production without waste water, waste gas or pollution so as to truly realize the rubber recycling economy.
Description
Technical field
The present invention relates to a kind of regeneration reducing rubber manufacturing process, particularly a kind of waste old reducing/regenerating EPDM rubber manufacturing process.
Background technology
The history in existing more than 130 year of conventional regeneration glue industry.In recent years, China's reclaimed rubber production also has bigger development, has nowadays surpassed 2,500,000 tons the scale of producing per year.The crowd knows week, and the production method of reclaimed rubber is normally classified according to sulfur method.Temperature classification when having with desulfurization abroad is high temperature method more than 100 ℃, is low temperature process below 100 ℃.The domestic industry renovation process mainly contains oil process, water/oil method, desulfurization rapidly method, screw rod doctor treatment and dynamic desulfurization etc. at present.Oil process and water/oil method all are in digester, to be heated to more than 170 ℃ through electrical heating or oil after waste rubber grain and the catalyst mix, and keep about 6h.Owing to be to adopt the long-time oxicracking of high temperature and utilize a large amount of oils swelling vulcanized rubbers.Therefore reclaimed rubber obvious degradation, its physical property is relatively poor and limited the scope of application.The hot strength of reclaimed rubber generally is no more than 10MPa, and homogeneous raw material micelle hot strength is about 20MPa.Therefore it can only do cheap packing material use; And because oil process and the water/oil method energy consumption is high, seriously polluted, production efficiency is low; Progressively eliminated now, dynamically desulfurization is a new developing technology in recent years, and it has overcome some problems that oil process occurs aborning; Alleviated partly and polluted, product quality and production efficiency have also obtained corresponding raising.But still exist shortcomings such as energy consumption height, pollution and properties of product deficiency inevitably.Owing to belong to traditional industries, start easily dog-eat-dog.Because production cost is high, profit is very little, adds the pollution of wanting the recovery of three wastess(waste gas,waste water and industrial residue), and reclaimed rubber enterprise is made the matter worse.
Summary of the invention
Technical problem to be solved by this invention provides a kind of regenerating waste or used rubber reduction manufacturing process, produces low cost, high-quality, free of contamination reclaimed rubber.
Major technique of the present invention thes contents are as follows:
A kind of regeneration reducing rubber manufacturing process may further comprise the steps:
A, at first the roll spacing of mill is adjusted to zero, the machine rotating speed of beginning to pratise is adjusted to 40 commentariess on classics/per minutes, and micelle and scrap rubber rim charge are pressed refining once, will cooperate raw material adding pressure to refine again 10 minutes;
B, adjust mill then roll spacing to 0.5mm, add processing aid and mixing again 5 minutes slices of elastomeric compound, temperature is controlled within 40-60 ℃;
After c, the slice,, process finished product with the vulcanizer sulfuration.
As preferred version, the mill among the above-mentioned steps a can replace with conche.
As preferred version, micelle is the 10-40 order among the above-mentioned steps a, and the scrap rubber rim charge is 50-100 part.
As preferred version, cooperating raw material among the above-mentioned steps a is the reducing/regenerating agent.
As preferred version, above-mentioned reducing/regenerating agent is 2-3 part.
As preferred version, the composition of elastomeric compound is following among the above-mentioned steps b: but vulcanizing agent 2-3 part, promoter 1-2 part, age resistor 2-3 part, 10 parts of plastic cement 2-3 of rubber part, filler 10-12 part.
By technique scheme, the present invention has advantage at least:
Reduced production cost, improved production efficiency, product quality; The present invention has simultaneously satisfied 21 century to requirement on environmental protection; Make it along economic model capable of circulation, sustainable development; Realize no waste water, no waste gas, free of contamination environment-friendly type production, thereby really realized the recycling economy of rubber.
The specific embodiment of the present invention is provided by following examples in detail.
The specific embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with preferred embodiment, to its specific embodiment, structure, characteristic and the effect thereof that proposes according to the present invention, specify as after.
A kind of regeneration reducing rubber manufacturing process may further comprise the steps:
A, at first the roll spacing of mill is adjusted to zero, the machine rotating speed of beginning to pratise is adjusted to 40 commentariess on classics/per minutes, and micelle and scrap rubber rim charge are pressed refining once, will cooperate raw material adding pressure to refine again 10 minutes;
B, adjust mill then roll spacing to 0.5mm, add processing aid and mixing again 5 minutes slices of elastomeric compound, temperature is controlled within 40-60 ℃;
