Abstract
The invention discloses a process for manufacturing a rubber floor tile. Raw materials include polyoxypropylene polyether glycol, toluene diisocyanate and waste rubber particles. A prepolymer method is adopted in an isocyanate production process. The physical and mechanical performances of a material prepared by using a one-step method are poorer than those of the prepolymer method, and particularly the tensile strength difference is relatively high. The reasons are as follows: polyether glycol is only simply mixed with TDI in the one-step method, a prepolymerization process is omitted, and part of free TDI does not react with polyether glycol, but directly reacts with water or active hydrogen on the surfaces of rubber particles, so that polyether glycol is relatively surplus to play a role of a plasticizer, macromolecules cannot be formed, and the adhesiveness is poor. By using the prepolymer method, polyether glycol reacts with TDI to generate a prepolymer containing a -NCO group and reacts with water and active groups on the surfaces of the rubber particles to form macromolecules, so that the adhesiveness is good, and the tensile strength is remarkably enhanced.
Description
Technical field
The present invention relates to rubber item and manufacture field, is a kind of raw material and technique thereof of manufacturing rubber floor tile in particular.
Background technology
Current China has become rubber item big producing country of the world, along with the continuous increase of the rubber item output such as tire, sebific duct, adhesive tape, have a large amount of rubber products to scrap every year, waste old has become the another large public hazards after " white pollution ", is called " black pollution ".Waste old is evil is again precious, and it can not be destroyed and can not stack for a long time, destroys or stack all can have a strong impact on ecotope.Waste old has again many premium propertiess, as good in good springiness, weather resistance, frictional coefficient greatly, not easily aging etc.The process majority of waste old adopts the method for regeneration in the past, but due to the performance of regenerated rubber, consumption limited, added value is lower, and has the suspicion of secondary pollution, so its development is in falling tendency.For this reason, many countries or research institution drop into a large amount of human and material resources, adopt special method process waste old, turn bane into boon, turn waste into wealth.Wherein, the waste rubber goodses such as the old tire of recovery are obtained rubber micelle through pulverizing, and adding a small amount of polyurethane binder is bondd, and obtains resilient floor tile, has larger economic worth.The elastic rubber floor tile that waste old is produced is 21 century " sunrise industry " full of hope, and domestic and international existing market and market potential demands are huge, and development situation is very optimistic.
Summary of the invention
The invention provides a kind of raw material and the technique that manufacture rubber floor tile, for realizing object of the present invention, technical scheme of the present invention is as follows:
Manufacture rubber floor tile a raw material, its raw material comprises: propylene oxide polyether polyvalent alcohol, tolylene diisocyanate, waste rubber grain.
Manufacture a technique for rubber floor tile, concrete steps are as follows:
(1) preparation of sizing agent
In the 3 mouthfuls of apparatus for preparation having agitator, temperature controller, vacuum interface, add quantitative polyether glycol, in 100 ~ 120 DEG C, dewater under-0098MPa to bubble-free, be then cooled to 80 DEG C, add the vulcabond that the employing single stage method of metering is obtained, reaction 15 ~ 2h under the condition of (80 ± 2) DEG C, then degassed to bubble-free, add emulsifying agent, solidifying agent, obtain adhesive components.
(2) preparation of rubber floor tile
Take the waste rubber grain of 4kg, add the tackiness agent of 500g and mix to pour in mould and flatten, at room temperature make it solidify test piece.
Preferably, prepared by the single stage method in step (1) isocyanic ester to change to and prepare isocyanic ester by pre-thing method.
Beneficial effect: the Material Physics mechanical property that single stage method obtains is all poor than prepolymer method, especially tensile strength difference is larger.Its reason is: in single stage method, polyether glycol just simply mixes with TDI, without pre-collecting process, the TDI that part is dissociated does not react with polyether glycol, and with the moisture on rubber grain surface or reactive hydrogen direct reaction, make polyether glycol relative surplus, serve the effect of softening agent, can not macromole be formed, poor adhesion.And prepolymer method makes polyether glycol and TDI first generate prepolymer containing-NCO base, react with the moisture on rubber grain surface and active group, formation macromole, binding property is good, and tensile strength obviously increases.
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.
Rubber floor tile a manufacturing process, its raw material comprises: propylene oxide polyether polyvalent alcohol, tolylene diisocyanate, waste rubber grain.
Described raw material manufactures a technique for rubber floor tile, and concrete steps are as follows:
(1) preparation of sizing agent
In the 3 mouthfuls of apparatus for preparation having agitator, temperature controller, vacuum interface, add quantitative polyether glycol, in 120 DEG C, dewater under-0.098MPa to bubble-free, be then cooled to 80 DEG C, add the vulcabond that the pre-thing method of employing of metering is obtained, 1.5h is reacted under the condition of (80 ± 2) DEG C, then degassed to bubble-free, add emulsifying agent, solidifying agent, obtain adhesive components.
(2) preparation of rubber floor tile
Take the waste rubber grain of 4kg, add the tackiness agent of 500g and mix to pour in mould and flatten, at room temperature make it solidify test piece.
The invention provides a kind of manufacturing process of rubber floor tile, its raw material comprises: propylene oxide polyether polyvalent alcohol, tolylene diisocyanate, waste rubber grain.Pre-thing method is used in isocyanic ester manufacturing processed.The Material Physics mechanical property that single stage method obtains is all poor than prepolymer method, and especially tensile strength difference is larger.Its reason is: in single stage method, polyether glycol just simply mixes with TDI, without pre-collecting process, the TDI that part is dissociated does not react with polyether glycol, and with the moisture on rubber grain surface or reactive hydrogen direct reaction, make polyether glycol relative surplus, serve the effect of softening agent, can not macromole be formed, poor adhesion.And prepolymer method makes polyether glycol and TDI first generate prepolymer containing-NCO base, react with the moisture on rubber grain surface and active group, formation macromole, binding property is good, and tensile strength obviously increases.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
