Embodiment 1
[0113] The by-product salt mud (slurry) of the chlor-alkali industry is removed with a plate and frame filter press to remove excess water and dried, then ground and sieved to obtain a 10 micron (μ) salt mud powder filler, using a melt flow rate (MFR) of 4 Linear low-density polyethylene (LLDPE) resin is used as the base material, and the mass fraction ratio of filler to resin is 300:100; auxiliary agent is: hindered phenol antioxidant is tetrakis[β-(3.5-di-tert-butyl, 4- Hydroxyphenyl) propionic acid] pentaerythritol ester, the addition is 0.3 parts by mass, and the phosphite stabilizer is three (2.4-di-tert-butylphenyl) phosphite, and the addition is 0.3 parts by mass; the average molecular weight is 4000 high flow polyethylene (PE wax), the addition amount is 1 part by mass; 40% carbon black master batch containing 35 parts by mass of carbon black. The above components are added in three stages according to the metering. The first stage adds all the resins, additives and fi...
Embodiment 2
[0115] Calcium carbonate of 6.5 microns (μm) is used as a filler, and a low-density polyethylene (LDPE) resin with a melt flow rate (MFR) of 0.3 is a base material, and the mass and number ratio of the filler to the resin is 200: 100; the auxiliary agent is : The hindered phenolic antioxidant is tetrakis [beta-(3.5-di-tert-butyl, 4-hydroxyphenyl) propionate] pentaerythritol ester, the addition is 0.3 parts by mass, and the phosphite stabilizer is tri(2.4 -Di-tert-butylphenyl) ester, the addition amount is 0.3 parts by mass; the melt flow rate (MFR) is 30 high flow polyethylene (PE), the addition amount is 1 parts by mass. Add the above components into the twin-screw granulator in three stages according to the metering. The first stage adds all the resins, additives and fillers in corresponding proportions. The proportion of fillers added in each stage is 40% and 40% of the total amount of fillers. , 20%, using a twin-screw granulator with a screw diameter of 75 (φ75) and a len...
Embodiment 3
[0117] Use 1.6 microns (μm) of calcium carbonate as a filler, a high-density polyethylene (HDPE) resin with a melt flow rate (MFR) of 0.1 as a base material, and the mass and number ratio of filler to resin is 150: 100; the auxiliary agent is: The hindered phenolic antioxidant is tetrakis [β-(3.5-di-tert-butyl, 4-hydroxyphenyl) propionic acid] pentaerythritol ester, the addition amount is 0.3 parts by mass, and the phosphite stabilizer is tri(2.4- Di-tert-butylphenyl) ester, the addition amount is 0.3 parts by mass; the high flow polyethylene (PE) whose melt flow rate (MFR) is 70, the addition amount is 3 parts by mass. Add the above components into the twin-screw granulator in four stages according to the metering. The first stage adds all the resins, additives and fillers in corresponding proportions. The proportion of fillers added in each stage is 30% and 30% of the total amount of fillers. , 30%, and 10%, use a twin-screw granulator with a screw diameter of 75 (φ75) and a...
