[0025] Step 1: In parts by weight, add 50 parts of 1000-mesh talc powder into the mixing pot and mix at high speed to 110°C to remove the moisture, then add 1.5 parts of titanate coupling agent (NDZ105) and mix at high speed for 4 minutes , then add 50 parts of PP resin, 0.5 parts of antioxidant (1010), 0.5 parts of ultraviolet absorber (UV-531), mix for 3 minutes, put it into the cold mixing pot and mix it to 45 ° C for feeding;

[0026] Step 2: Use the co-rotating parallel twin-screw extruder to prepare the PP reinforced filling masterbatch through the steps of drawing, water cooling, pelletizing and drying with the co-rotating parallel twin-screw extruder. The operation process is as follows:

[0027] Host speed: 300r / min; Feeding speed: 75r / min;

[0028] Set the temperature of each section of the screw: barrel 1: 170°C; barrel 2: 175°C; barrel 3: 180°C; barrel...

Embodiment 2

[0036] Prepare described PP / PE environment-friendly fence composite material according to the following steps:

[0037] Step 1: In parts by weight, add 70 parts of 1000 mesh talc powder into the mixing pot and mix at high speed to 115°C to remove the moisture, then add 2 parts of titanate coupling agent (NDZ105) and mix at high speed for 6 minutes , then add 70 parts of PP resin, 0.8 parts of antioxidant (1010), 0.8 parts of ultraviolet absorber (UV-531), mix for 4 minutes and put it into the cold mixing pot to cool and mix to 45 °C for feeding;

[0038] Step 2: Use the co-rotating parallel twin-screw extruder to prepare the PP reinforced filling masterbatch through the steps of drawing, water cooling, pelletizing and drying with the co-rotating parallel twin-screw extruder. The operation process is as follows:

[0039] Host speed: 350r / min; Feeding speed: 90r / min;

[0040] Set the temperature of each section of the screw: barrel 1: 176°C; barrel 2: 179°C; barrel 3: 186°C; b...

Embodiment 3

[0048] Prepare described PP / PE environment-friendly fence composite material according to the following steps:

[0049] Step 1: In parts by weight, add 100 parts of 1000 mesh talc powder into the mixing pot and mix at high speed to 120°C to remove the moisture, then add 3 parts of titanate coupling agent (NDZ105) and mix at high speed for 8 minutes , then add 100 parts of PP resin, 1.0 part of antioxidant (1010), 1.0 part of ultraviolet absorber (UV-531), mix for 5 minutes, put it into the cold mixing pot and mix it until it is 45 °C for feeding;

[0050] Step 2: Use the co-rotating parallel twin-screw extruder to prepare the PP reinforced filling masterbatch through the steps of drawing, water cooling, pelletizing and drying with the co-rotating parallel twin-screw extruder. The operation process is as follows:

[0051] Host speed: 400r / min; Feeding speed: 100r / min;

[0052] Set the temperature of each section of the screw: barrel 1: 179°C; barrel 2: 180°C; barrel 3: 189°C;...

Abstract

The invention relates to a manufacture method and the purpose of a PP / PE environment-friendly fencing composite material. Superficial treatment is carried out on inorganic filler, then part of polypropylene resin is used as carrier to prepare reinforcing filling master batch which is prepared into the needed PP / PE environment-friendly fencing composite material together with the rest resin; and the manufactured PP / PE environment-friendly fencing composite material is used for manufacturing an environment-friendly fencing. Due to the adoption of the technical scheme, the prepared PP / PE environment-friendly fencing composite material has favorable rigidity and heat resisting property, and the impact strength and the toughness are obviously improved compared with those of the traditional bamboo wood and hard PVC material; the product has excellent performances of damp and corrosion resistance, good resistance to elements and worm and epiphyte resistance without bane or oil paint and makes up the defects of the bamboo wood and hard PVC materials; the scrapped material during the manufacture process can be reclaimed and used, therefore, the invention accords with the policy of developing environment-friendly circulating industry of the nation and benefits both the nation and the people.

Description

technical field [0001] The invention relates to a manufacturing method and application of fence composite materials, in particular to a manufacturing method and application of environment-friendly fence composite materials. Background technique [0002] With the continuous improvement of living standards, people's requirements for living environment are getting higher and higher, especially in some newly developed living quarters, parks or squares, ornamental flowers, trees and lawns are generally planted to protect these flowers and plants. When it comes to trees, various styles of fences are commonly used. [0003] At present, most of the outdoor fence materials in China are made of bamboo or hard PVC materials. Fences made of bamboo and wood materials have a series of advantages such as light weight and beautiful appearance. However, my country's forest resources are relatively scarce, and the per capita forest occupancy rate is lower than the world average. , and a large...
