It is squeezed out to being heated in extruder;
(2)Extruded machine squeezes out finished product after postcooling, deburring.
The present invention is further arranged to:Heating temperature in the extruder is 180-220 DEG C.
In conclusion the invention has the advantages that:
The creation point of the present invention is:In the prior art, polypropene recycled materials have the following problems in the production of black material:Again
Raw material poor quality, and mechanical property reduces after repeatedly processing, brittleness enhancing is easy cracking.For the technical problem, this Shen
Please file propose and add linear low density polyethylene (LLDPE) in polypropene recycled materials.Linear low density polyethylene (LLDPE) has preferable resistance to
Environmental Stress Cracking, the performances such as impact strength, tear-resistant intensity, can preferably improve the brittleness of polypropene recycled materials compared with
Big problem.Since the fusing point of linear low density polyethylene (LLDPE) is 110-125 DEG C, and the fusing point of polypropene recycled materials is 164-170
℃.Heating temperature in present specification is 180-220 DEG C.At a high temperature of 180-220 DEG C, the heat of linear low density polyethylene (LLDPE)
Oxidation is stronger so that the physical property of linear low density polyethylene (LLDPE) reduces.To solve the problems, such as this, present specification is in system
In be added to antioxidant 1010, with achieve the effect that reduce thermal oxidation.It also added EVA plastic materials, EVA modelings in system
Collagen material has the characteristics that low temperature resistant, high intensity, toughness are strong, environmental stress crack resistance is good, and heat decomposition temperature is relatively low, about
230 DEG C or so.Therefore control heating temperature, which is 180-220 DEG C, can prevent EVA plastic materials from decomposing, and influence EVA plastic materials
Physicochemical property.EVA plastic materials have preferably by capacitive, and more reinforcing filler can be added in EVA plastic materials
Improve the mechanical property of EVA plastic materials.The mechanical property of system is improved by adding black powder in system.But by
The uniformly mixed difficulty of whole system can be excessively reduced in filler.Therefore, maleic anhydride inoculated polypropylene is added in system.Horse
Maleic anhydride grafted polypropylene can improve the dispersibility of filler and polypropylene compatibility and filler.Therefore can effectively reinforcing filler it exist
Dispersion in polypropylene, to improve stretching and the impact strength of filled polypropylene.Meanwhile PP waxes are added into system.When poly-
After adding a large amount of filler materials in propylene reworked material, injection molding extrusion difficulty is higher, and product surface is coarse, not easy mold release, is added appropriate
PP waxes after can improve system mobility, so that material is mixed, dissolve each other make product be easy demoulding, improve finished product finish.Meanwhile PP
The addition of wax can further prevent thermal oxidation so that under the double action of PP waxes and antioxidant, linear, low density is poly-
The physical property of ethylene will not be affected in extrusion.
In conclusion polypropene recycled materials content in the prior art is very big, even up to 100%.And in present specification
Reduce reworked material content so that reworked material content is maintained between 80-90%, and is added to linear low density polyethylene (LLDPE) conduct
Improve the larger problem of reworked material brittleness so that the quality of reworked material is preferable.Black powder is added to dye reworked material.Simultaneously
PP waxes are added as flow promortor so that the mobility of each component is preferable in system, equal to reach component mixing in system
Even purpose.Add antioxidant 1010 simultaneously.Under the double action of antioxidant 1010 and PP waxes, linear low density polyethylene (LLDPE)
Thermal oxidation is smaller, so that the physical property of linear low density polyethylene (LLDPE) will not be a greater impact.By in system
Middle addition maleic anhydride inoculated polypropylene so that be coupled between the filler and reworked material in system, so that system tends to be steady
It is fixed.Cohesive force between component and component is larger, improves stretching and the impact strength of system.Finally, the EVA plastic materials of addition
The low temperature resistant of system, impact flexibility and environmental stress crack resistance can be improved, further increase the intensity of reworked material, reduced
Brittleness.Since the molecular weight of EVA plastic materials is larger, processability and the finished surface glossiness produced reduce, to solve
This problem.The addition of PP waxes can improve the mobility of system so that mix between component, and can solve EVA plastic cement
The problem that difficulty of the raw material in production is big, glossiness is low.PP waxes improve the mobility of EVA plastic materials, to reduce
The difficulty of processing of EVA plastic materials, and PP waxes can improve the glossiness of finished product, to solve due to EVA plastic materials
Problem caused by addition.
