[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0030] In the first aspect, the present invention provides a heat-resistant polymer material formula, which includes the following components in parts by weight: 60-80 parts of polypropylene, 20-50 parts of insulating rubber, 6-10 parts of nano-MgO, 10-14 parts of PP particles, 10-14 parts of POE particles, 4-6 parts of nano-Al2O3, 16-20 parts of polyurethane, 5-8 parts of adhesive, 3-5 parts of flame retardant, 10-15 parts of flexibility agent, and 1-4 parts of antioxidant.
[0031] Through the composite effect of polypropylene, insulating rubber, nano Mg, PP particles, POE particles, nano Al2O3, polyurethane, adhesives, flame retardants, flexibility agents, and antioxidants, the formula of the heat-resistant polymer material is optimized, so that the heat-resistant polymer material has the advantages of multiple polymer materials, thereby making up for the shortcomings of each polymer material and having better heat resistance, weather resistance, flexibility, insulation and other properties to meet the actual use needs of the polymer material. Polyurethane has the advantages of excellent tensile strength, tear strength, impact resistance, weather resistance and other advantages, which makes the polymer material have good weather resistance.
[0032] The insulating rubber is nitrile rubber.
[0033] Nitrile rubber has good heat resistance and wear resistance, thus ensuring the heat resistance of polymer materials.
[0034] The adhesive is epoxy resin.
[0035] The good heat resistance and electrical insulation of epoxy resin make this polymer material have good heat resistance and insulation.
[0036] The flame retardant is aluminum hydroxide phosphate flame retardant.
[0037] Flame retardants are substances that can increase the flame resistance of polymer materials.
[0038] The flexibilizer is composed of tetrahydrophthalic anhydride derivatives of alkyl and ester alkyl, phthalic anhydride and epoxy resin, and the antioxidant is a special ozone-proof antioxidant composed of aminodiphenylamine, hydrogen and octanone.
[0039] Through the synergistic effect of the flexibilizer and the antioxidant, the flexibility of the polymer material is effectively improved, the anti-aging effect of the polymer material is increased, and it also has an odorless and tasteless effect. At the same time, it avoids or reduces the cracking of the polymer material, has a protective effect, and extends the service life.
[0040] Second, as Figure 1 , Figure 2 As shown, the present invention also provides a method for producing a heat-resistant polymer material, the production method comprising the following steps:
[0041] S1: weigh the corresponding raw materials;
[0042] S2: Preparation of PP nanocomposites;
[0043] S3: filled with polyurethane, nitrile rubber;
[0044] S4: The raw materials are mixed, extruded into granules, and then packaged.
[0045] S2 includes the following steps:
[0046] S21, drying: putting the nano-MgO, PP particles, and POE particles into a dryer and drying them at 60° C. to remove moisture;
[0047] S22, preparing PP masterbatch: putting nano-MgO and PP particles into an extruder for mixing, and extruding the raw materials into a granulator for granulation treatment to obtain a PP masterbatch containing 20% by mass of MgO, and then putting the PP masterbatch into a dryer for drying;
[0048] S23, extrusion and cooling: PP masterbatch, POE granules and PP granules are put into an extruder, mixed and extruded onto a conveyor belt for air cooling and forming, and then set aside.
[0049] S3 includes: using nano-Al2O3 mixed to fill nitrile rubber, and using polyurethane mixed to fill Al2O3 with a volume fraction of 20%.
[0050] S4 includes: putting polypropylene, PP nanocomposite, polyurethane, insulating rubber, adhesive, flame retardant, flexibilizer and antioxidant into a reactor, stirring and mixing the raw materials with a stirrer, and finally putting the mixed raw materials into an extruder. The extruder squeezes the raw materials into a granulator for granulation, and then cools and packages them to obtain the finished heat-resistant polymer material.
[0051] Drying the raw materials with a dryer shortens the processing cycle and is beneficial to the subsequent processing of the raw materials. The raw materials are mixed, extruded and granulated using a reactor, agitator, extruder and granulator. Complex processing equipment is not required and the process flow is simple.
[0052] In summary, nano-MgO, PP particles, and POE particles are put into a dryer to remove moisture, and then nano-MgO and PP particles are put into an extruder for mixing, and the raw materials are extruded into a granulator for granulation to obtain a PP masterbatch containing 20% of MgO by mass. The PP masterbatch is put into a dryer for drying. Nano-MgO can act as a heterogeneous nucleating agent, induce the formation of B crystals, and increase the crystallinity by about 4%, thereby improving the heat resistance of the material. The PP masterbatch, POE particles, and PP particles are put into an extruder for mixing and extruding onto a conveyor belt for air cooling and molding. Polypropylene, PP nanocomposites, polyurethane, insulating rubber, adhesives, flame retardants, flexibilizers, and antioxidants are put into a reactor and stirred with a stirrer. The raw materials are stirred and mixed, and finally the mixed raw materials are put into an extruder. The extruder squeezes the raw materials into a granulator for granulation. After cooling, the finished heat-resistant polymer material is packaged, and the antioxidant is a special anti-ozone antioxidant composed of aminodiphenylamine, hydrogen and octanone. The heat-resistant polymer material prepared in this way is odorless and tasteless, and the formula of the polymer material is optimized. Through the synergistic effect of various raw materials, the heat-resistant polymer material has the advantages of various polymer materials, thereby making up for the deficiencies of various polymer materials, so that it has better heat resistance, weather resistance, flexibility, insulation, anti-aging and other properties, effectively improving the flexibility and anti-aging of the heat-resistant polymer material, meeting the actual use needs of the polymer material, and having strong interference ability.
[0053] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
