Embodiment 1

[0021] Weigh 63 parts by weight of PP regrind, 27 parts by weight of glass fiber, 4 parts by weight of calcium carbonate and 6 parts by weight of high-pressure PE, melt and mix the raw materials, and then transport the mixed melt to the extrusion Extrude from the machine for cooling and molding, cut into pellets after extrusion, mark as material 1 and test the performance of material 1. Then, the material 1 is made into the leveling angle of the electrical appliance by thermoforming.

Embodiment 2

[0023] Weigh 65 parts by weight of PP regrind, 25 parts by weight of glass fiber, 5 parts by weight of calcium carbonate, 5 parts by weight of high-pressure PE, and a small amount of flame retardant powder. The raw materials are melted and mixed, and then mixed The homogenous melt is transported to the extruder for extrusion cooling and molding. After extrusion, it is cut into pellets, marked as material 2 and the performance of material 2 is tested. Then the material 2 is made into auto parts by thermoforming.

Embodiment 3

[0025] Weigh 67 parts by weight of PP regrind, 23 parts by weight of glass fiber, 6 parts by weight of calcium carbonate and 4 parts by weight of high-pressure PE, melt and mix the raw materials, and then transport the mixed melt to the extrusion Extrude from the machine for cooling and molding, cut into pellets after extrusion, mark it as material 3 and test the performance of material 3. Then, the material 3 is made into the leveling angle of the electrical appliance by thermoforming.

[0026] The performance of PP material (marked as material 4) modified by calcium carbonate that is commonly purchased on the market is tested. The specific test results of each material are as follows:

Abstract

The invention discloses a modified PP (Polypropylene) material. The modified PP material is prepared from the following raw materials in parts by weight: 63-67 parts of recycled PP material, 23-27 parts of glass fiber, 4-6 parts of calcium carbonate and 4-6 parts of high-pressure PE (Poly Ethylene). In the scheme, the recycling of the PP material is realized by recycling and modifying the PP material, so as to avoid the problems of environmental pollution and resource waste caused by direct discarding or burning of the PP material, meanwhile the modified PP material has excellent strength, deformation, shrinkage, smooth surface, heat resistance and the like, and can be used as a raw material for the production of different products.

Description

technical field [0001] The invention relates to the field of plastic recycling, in particular to a modified PP material and its application. Background technique [0002] Polypropylene (PP material) is a thermoplastic resin material made by propylene polymerization, and it is an important variety among the five general-purpose synthetic resins. PP is the smallest density of all synthetic resins, only 0.90~0.91g / cm 3 , Among the five general-purpose plastics, PP has excellent heat resistance, PP is a non-polar polymer, has good electrical insulation, and PP has extremely low water absorption, and electrical insulation will not be affected by humidity. Therefore, polypropylene is made into various products by methods such as injection molding, extrusion, blow molding, and thermoforming, and is widely used in the fields of packaging, automobiles, home appliances, building materials, and chemicals. However, at present, after PP materials are used, they usually cannot be direct...
