For the deficiency that prior art exists, the invention provides a kind of process for subsequent treatment of waste rubber of turning waste into wealth.

To achieve these goals, the present invention realizes by the following technical solutions:

A process for subsequent treatment for waste rubber,

1) pulverize: waste Crumb rubber is broken into 100 ~ 300 object rubber powders;

2) cleaning: rubber powder is used respectively successively the mixture of ethanol and ether, acetone and deionized water ultrasound filtration cleaning half hour in industrial ultrasonic machine respectively, then clean three times by 93# gasoline and deionized water order;

3) melt: cleaned rubber powder is put into reactor, 300 DEG C, under agitation condition, heat 30min, make it become melting cement state;

4) modification: add oxygen plasma activated carbon pipe, treated starch and pigment in reactor, stir with rubber cement; The content of described oxygen plasma activated carbon pipe is 1% ~ 5%, and the content of described treated starch is 3% ~ 8%;

5) vacuum defoamation: be evacuated by reactor, takes the air dissolved in rubber cement away, sloughs the bubble in rubber cement;

6) shape: from reactor, release rubber cement in mould, vacuum cooling 3 ~ 4h, when rubber cement becomes half-dried, sprinkle the mixture of magnesium aluminum-hydrotalcite, ammonium polyphosphate and magnesium hydroxide, then cool 3 ~ 4h, to complete drying;

In the mixture of described magnesium aluminum-hydrotalcite, ammonium polyphosphate and magnesium hydroxide, the ratio of magnesium aluminum-hydrotalcite, ammonium polyphosphate and magnesium hydroxide is 2:1:2;

7) sulfuration: use sulphur and calcium carbonate to carry out at 130 ~ 140 DEG C, sulfuration 30min under pressure 15MPa condition, passes into hydrogen sulfide in sulfidation, helps sulfuration complete.

In the process for subsequent treatment of above-mentioned waste rubber, described step 2) in, in the mixture of described ethanol and ether, ethanol: ether=5:2.

In the process for subsequent treatment of above-mentioned waste rubber, described step 4), described oxygen plasma activated carbon pipe treatment condition are under vacuum stirring condition, and high temperature leads to oxygen 1h process carbon pipe.

In the process for subsequent treatment of above-mentioned waste rubber, described step 4) in, described treated starch is cross-linking starch.

Beneficial effect: by waste rubber through pulverizing, cleaning, melt, modification, vacuum defoamation, after the process of sizing and sulfuration seven steps, not only turn waste into wealth, and pass through after a series of process of waste rubber, purify old rubber, increase the ductility of regenerative ratio rubber, oxidation-resistance and flame retardant resistance, pulverizing rubber powder size is suitable, process without the need to using meticulous instrument, water-soluble and the lipid-soluble substance on cleaning removing scrap rubber surface, improve scrap rubber quality, in modification, oxygen plasma activated carbon pipe improves resistance of aging, increase the service life, treated starch add increase ductility, the ugly color adding mediation scrap rubber of pigment, to the visual sense of security of client, vacuum defoamation increases rubber compactness, when rubber cement becomes half-dried, sprinkle magnesium aluminum-hydrotalcite, the mixture of ammonium polyphosphate and magnesium hydroxide, mixture is adsorbed in rubber surface, play fire-retardant effect.

Embodiment

The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.

Embodiment 1:

1) pulverize: waste Crumb rubber is broken into 100 ~ 300 object rubber powders, rubber powder size is suitable, processes without the need to using meticulous instrument.

2) clean: rubber powder is used respectively successively the mixture of ethanol and ether, acetone and deionized water ultrasound filtration cleaning half hour respectively, clean three times by 93# gasoline and deionized water order again, water-soluble and the lipid-soluble substance on removing scrap rubber surface, improves scrap rubber quality.

3) melt: cleaned rubber powder is put into reactor, under 300 DEG C of conditions, heats 30min, make it become melting cement state.

4) modification: add oxygen plasma activated carbon pipe, treated starch and pigment in reactor, stir with rubber cement, the content of described oxygen plasma activated carbon pipe is 4%, the content of described treated starch is 5%, oxygen plasma activated carbon pipe improve resistance of aging, increase the service life, treated starch add increase ductility, the ugly color adding mediation scrap rubber of pigment, to the visual sense of security of client.

5) vacuum defoamation: be evacuated by reactor, takes the air dissolved in rubber cement away, sloughs the bubble in rubber cement, increases rubber compactness.
