Description
Technical field
The present invention relates to the regenerating technology for waste rubber field, specifically is a kind of method that coupling agent prepares the high-tenacity shoddy that adds.Be utilized in the materials such as shoddy regenerated rubber powder and add coupling agent, utilize the interaction of coupling agent and material, prepare the high-tenacity shoddy.
Background technology
The quantity of waste old material is only second to plastic waste in spent high molecular material, wherein learies is more than 1,000,000,000 doughnut whole world year, and China is at 5000～6,000 ten thousand.The recycling of waste old is main with junked tire, and other also comprises the waste and old rubber overshoes and the inner tube of a tyre etc., and the utilization of waste rubber helps protecting environment, realizes the utilization again of resource, helps continuous development of society economy.
At present, shoddy only can used or directly be used for preparing to conventional regeneration glue intensity in low-grade rubber product about 8MPa.The applicant had once applied for " method of environment-friendly type high intensity power shoddy ", the tensile strength of the shoddy of production more than 18 MPa, elongation rate of tensile failure is more than 420%.
Coupling agent is one type of material with two different properties functional groups; Discover through us; Coupling agent has also been participated in the regeneration chemical reaction of waste rubber powder except helping mineral filler disperses in materials such as waste rubber powder and regenerator, sem analysis shows; Coupling agent has strengthened regenerator, filler and has combined with interface between shoddy, and the interface performance is very fuzzy.But in the regenerative process of in the past waste old, find to use the precedent of coupling agent.
Summary of the invention
For further improving the mechanical property of shoddy, replace synthetical glue or partly replace natural gum with the high-tenacity shoddy.The present invention provides a kind of method that coupling agent prepares the high-tenacity shoddy that adds, and in the production of high-tenacity shoddy, adds coupling agent, with the performance of further raising shoddy, makes the shoddy performance of acquisition that further lifting arranged.
The present invention realizes with following technical scheme: a kind ofly add the method that coupling agent prepares the high-tenacity shoddy; It is characterized in that: the 20 order waste rubber powders that partly prepare with waste and old heavy load radial tire crown, waste and old crown compound of bias truck tire are raw material, add tenderizer, coupling agent and regenerator preparation; Stockholm tar, rosin, tall oil or the wood tar oil of described tenderizer for from plant, extracting, consumption is 12% of a waste rubber powder quality; Described coupling agent is γ-(methacryloxy) propyl trimethoxy silicane (KH570), and consumption is 2% of a waste rubber powder quality; Described regenerator adopts WR-510, and consumption is 0.5% of a ground rubber quality; Concrete steps are following:
(1) the waste and old heavy load radial tire crown of at first strict screening, waste and old crown compound of bias truck tire partly prepare 20 order rubber powders;
(2) process according to following order of addition(of ingredients), quantitatively take by weighing earlier thick liquid tenderizer and regenerator WR-510, use preceding in whipping appts heated and stirred, then the two is mixed; And then evenly sneak into coupling agent and further stir the formation mixture;
(3) 20 order rubber powders and said mixture material are regenerated in Banbury mixer, 170 ℃ of regeneration temperatures, 3.5 hours recovery times, it is 0.4MPa that pressure is fastened on last top;
(4) the good sizing material of will regenerating adds mill and carries out refining, in the mill through roll spacing at 0.5mm under the thin logical shoddy of preparing any surface finish, having tackiness and intensity for 10 times of low temperature;
(5) according to the National Standard regenerated rubber " GB/T 13460-2008 regenerated rubber formula successively with the various Synergist S-421 95s in the Performance Detection prescription add carry out in the shoddys mixing; Then rubber unvulcanizate is parked sulfuration; After parking 24h again, sizing material is carried out physical and mechanical properties and process industrial art performance is tested.
The shoddy quality surface that obtains according to the present invention is bright and clean, the color quality is even.Carry out formulating of recipe, vulcanize, park, detect according to GB, the tensile strength of prepared shoddy is more than 19.5MPa, and elongation rate of tensile failure is more than 500%.
The invention has the beneficial effects as follows: the shoddy performance of producing with method of the present invention improves, and such shoddy can directly be used for the production of middle-grade rubber item, also can be used for mixing of high-grade rubber item, and it is big that the field of use becomes.Reduce the regenerated temperature, shortened the regenerated time, thereby reduced the energy expenditure of processing.This product is environmentally friendly, has outstanding economic benefit and social benefit.
Embodiment
Further illustrate scheme of the present invention and effect below in conjunction with an embodiment.
