Embodiment 1

[0032] After dissolving 3% by weight of apel6509 in toluene solution, add it to the reaction kettle under nitrogen atmosphere, add 17% by weight of molten K9026 resin to the reaction kettle, and add 0.5% by weight of MoCl 5 -AlEt 3 Catalyst, heated to 190°C, kept stirring for 40min, filtered out the solid, soaked the filtered solid in acetone for 2h, put it in an oven, and dried it at 60°C to obtain 20% by weight COC / PP copolymer . The obtained 20% by weight COC / PP copolymer and 77.1% by weight of K9026 resin, 0.2% by weight of antioxidant 1010, 0.2% by weight of antioxidant 168, 0.5% by weight of E525, and 2.0% by weight of M-1020 were added to the compound In the machine, the control speed is 850rpm, and the stirring time is 4min; the mixed material is extruded and granulated through a co-rotating twin-screw extruder.

Embodiment 2

[0034] After dissolving 5% by weight of apel6509 in toluene solution, add it to the reactor in nitrogen atmosphere, add 15% by weight of molten K9026 resin to the reactor, and add 0.5% by weight of MoCl 5 -AlEt 3 Catalyst, heated to 190°C, stirring continuously for 60min, after filtering out the solid, soak the filtered solid in acetone for 2.5h, then put it in an oven, and dry it at 80°C to obtain 20% by weight COC / PP copolymer thing. The 20% by weight COC / PP copolymer and 77.1% by weight of K9026 resin, 0.2% by weight of antioxidant 1010, 0.2% by weight of antioxidant 168, 0.5% by weight of E525, and 2.0% by weight of PMW301 were added to the mixer , the control speed is 850rpm, and the stirring time is 4min; the mixed material is extruded and granulated through a co-rotating twin-screw extruder.

Embodiment 3

[0036] After dissolving 8% by weight of apel6509 in toluene solution, add it to the reactor in nitrogen atmosphere, add 12% by weight of molten K9026 resin to the reactor, and add 0.5% by weight of MoCl 5 -AlEt 3 Catalyst, heated to 195°C, kept stirring for 50min, filtered out the solid, soaked the filtered solid in acetone for 3h, put it in an oven, and dried it at 75°C to obtain 20% by weight COC / PP copolymer . The 20% by weight COC / PP copolymer prepared with 77.1% by weight of K9026 resin, 0.2% by weight of antioxidant 1010, 0.2% by weight of antioxidant 168, 0.5% by weight of E525, and 2.0% by weight of M-1020 were added to the compound In the machine, the control speed is 850rpm, and the stirring time is 4min; the mixed material is extruded and granulated through a co-rotating twin-screw extruder.

Abstract

The invention provides a high-heat-resistance cold-resistant high-gloss metal-texture spraying-free polypropylene (PP) material and a preparation method thereof. The high-heat-resistance cold-resistant high-gloss metal-texture spraying-free PP material is prepared from the following components in percentage by weight: 83.0-95.8% of polypropylene resin, 3.0-12.0% of cyclic olefin copolymer (COC) resin, 0.1%-0.5% of an antioxidant, 0.1%-0.5% of a dispersing agent and 1.0%-4.0% of metal pigment. The preparation method comprises the steps: preparing a blend, carrying out mixing and carrying out extruding granulation. The spraying-free PP material provided by the invention has high gloss and metal texture, and also has high heat resistance and excellent cold resistance at the same time.

Description

technical field [0001] The invention relates to the modification of polypropylene materials, in particular to a spray-free PP material with high heat resistance and cold resistance, high gloss metallic texture and a preparation method thereof. Background technique [0002] Polypropylene resin (PP resin) compounded with metallic pigments such as pearl powder, copper powder, and aluminum silver bars can be extruded and granulated to produce high-gloss metallic PP materials. Due to the reflection of metal pigments on light, this material has the characteristics of high gloss and metallic texture. It can replace spray paint materials in the fields of electronic appliances, cosmetic packaging, automotive materials, etc., thereby reducing environmental pollution and reducing costs. However, due to the high requirements for the optical properties of this kind of high-gloss metallic texture free-spray PP material, it is necessary to avoid affecting its optical properties when modify...
