Abstract
A kind of recycling and the working method of the regeneration waste rubber owned by France of waste or used vulcanized rubber.In waste rubber, the regeneration of synthetic useless cross-linked rubber is difficulty, and the regeneration of making the waste water tire cross-linked rubber of scrapping in the tire is more difficult.The present invention adopts special additive and working method, can not add pure rubber and waste water tire glue is carried out manipulation of regeneration.The raw material that present method the adopts easy cheapness that is easy to get, the cost of finished product is low, the less investment of founding the factory.In addition, the anti-ozone ageing of the reclaimed rubber that the present invention produces is good, can be used to do water-proof material, and its weather-resistant property is for 30 years.
Description
The invention relates to the reclaiming and the working method of waste or used vulcanized rubber, particularly the renovation process of synthetic waste or used vulcanized rubber.
In waste or used vulcanized rubber, the regeneration of synthetic waste or used vulcanized rubber is the comparison difficulty.Particularly be used for making the employed curing bag of tire, if after scrapping, it is more difficult to desire regeneration, therefore normally that it is discarded both at home and abroad.
German Democratic Republic patent application DD-216-474-A discloses a kind of renovation process of waste or used vulcanized rubber.This method is to allow ground scrap and aldehydes react in alkaline solution and sulphur is sloughed, and, also in the sizing material that desulfurization is moulded again, added haloalkane and made it more stable.With regard to raw material, the regenerator that this method is added is somewhat expensive and be difficult to obtain.From the product performance of its suitability and recovery, this method is that difficulty makes waste and old curing bag rubber regeneration, and in addition, the product ozone-resistant aging property of regeneration gained is relatively poor.
The object of the present invention is to provide low, the wide adaptability of a kind of cost, the renovation process of the waste or used vulcanized rubber that regenerative sulfur binding is effective, the anti-ozone ageing of gained finished product is strong.
The objective of the invention is to realize as follows:
1. waste or used vulcanized rubber is classified, more various types of other scrap rubber separated pulverizing is become to be less than or equal to-36 purpose buffings.
2. mixing ingredient, it is mixing with additive natural resin, Stockholm tar, useless transformer oil, rosin or aniline that broken buffings is put into mill, and it is mixed into evenly and the softish sizing material.
3. add thermally desulfurizing, the sizing material of mixing mistake is put into the FAR INFRARED HEATING case add thermally desulfurizing.
4. refining treatment to adding the sizing material refining of thermally desulfurizing, adds the dispersion agent stearic acid during refining.
For the synthetic waste or used vulcanized rubber of more difficult desulfurization regeneration, as making the useless synthetical glue of the curing bag of scrapping in the tire process, present method is that its waste rubber that is divided into butyl, butylbenzene, Ethylene Propylene Terpolymer and neoprene four kinds is carried out above-mentioned processing.The natural resin that the present invention adds when mixing is that root and the skin of natural phant-red bayberry, rubber Bowl, olive and careless skin tree with Yunnan is the resin that the raw material destructive distillation forms.The major ingredient of this resin is that above-mentioned plant is refined Resin adhesive and the phenols that is left behind the spices.If mix small amount of phenol and formaldehyde in this natural resin, the regeneration effect of waste old can be better.In mixing process, the ratio of the weight of each component should be controlled in the following scope: ground scrap 100, natural gum 3.5～8, Stockholm tar 2～5, useless transformer oil 1.5～2, rosin 1～2 or aniline 0.3～0.5.Melting temperature is 120～140 ℃, and mixing time is 30～50 minutes.The temperature inside the box of the infrared heating case that the present invention uses in adding thermally desulfurizing should be 150～170 ℃, and everywhere the temperature difference is 1～2 ℃ in the case, and sizing material is 3～6 hours in the case internal heating time.More equal for the littler and sizing material of the temperature difference is heated, the both sides of case can be started blower fan and be formed and exchange thermal source.When refining, better in order to make sweetening effectiveness, the surface of glue is more smooth, and present method is that the stearic acid that adds 1.5 parts of weight in the sizing material of 100 parts of weight carries out refining.
The renovation process of waste or used vulcanized rubber of the present invention can not only be applied to common waste vulcanized glue, and can also be used for the synthetic waste vulcanized glue of the more difficult usefulness of making profits, and therefore, its suitability is wider.Produce reclaimed rubber by present method, the less investment of founding the factory, raw material is easy to get and is cheap, the advantage that product cost is low.Build a water-proof material factory that produces 2000 tons per year, only need invest 50～800,000 yuan.When producing reclaimed rubber, general usual way all will add a certain amount of pure rubber in scrap rubber, and present method can adopt waste and old sizing material fully, even the common waste water tire rubber that is not recycled also can not add pure rubber and regeneration.The additive natural resin that the present invention adopts when mixing is that natural phant-red bayberry, olive, rubber Bowl and the careless skin in Yunnan set rejectable wastes such as Resin adhesive remaining after refining spices and phenols, and these rejectable wastes generally do not re-use.This shows that the needed cost of material of present method is cheap and be easy to get, so production cost is lower.Produce reclaimed rubber by the present invention, the ozone-resistant aging property and the sweetening effectiveness of product are better, can be with it as water-proof material.This reclaimed rubber water-proof material had weather-resistant property more than 30 years, tensile strength 10～75kg/cm
