Embodiment 1

[0049] The first step is to put the inorganic powder into the high-speed mixer first, and stir at a high speed of 1200r / min to raise the temperature of the powder to 100°C and keep it for 10 minutes to exhaust the water vapor of the powder and open its agglomerated particles. Form a new interface, facilitate the action of the coupling agent, and form a hydrophobic and lipophilic structure;

[0050] In the second step, add an appropriate amount of coupling agent into the high-speed mixer, and stir at a high speed of 1500r / min for 5 minutes, and the powder is activated;

[0051] The third step is to add X2, opening agent and LDPE into the high mixer at the same time, and stir for several minutes; then add X1, X3, carrier resin and reinforcing material, and stir for several minutes at a speed of 1200r / min;

[0052] The fourth step is to put all the materials in the high mixer into the internal mixer, and internally knead through the internal mixer for 10 minutes, shear and disper...

[0060] The first step is to put the inorganic powder into the high-speed mixer and stir at a high speed of 1300r / min to raise the temperature of the powder to 100°C and keep it for 10 minutes to exhaust the water vapor of the powder and open its agglomerated particles. Form a new interface, facilitate the action of the coupling agent, and form a hydrophobic and lipophilic structure;

[0061] In the second step, add an appropriate amount of coupling agent into the high-speed mixer, and stir at a high speed of 1400r / min for 5 minutes, and the powder is activated;

[0062] The third step is to add X2, opening agent and LDPE into the high mixer at the same time, and stir for several minutes; then add X1, X3, carrier resin and reinforcing material, and stir for several minutes at a speed of 1300r / min;

[0063] The fourth step is to put all the materials in the high mixer into the internal mixer, and internally knead through the internal mixer for 10 minutes, shear and disperse even...

Embodiment 3

[0071] The first step is to put the inorganic powder into the high-speed mixer first, and stir at a high speed of 1500r / min to raise the temperature of the powder to 90°C and keep it for 9 minutes to exhaust the water vapor of the powder and open its agglomerated particles. Form a new interface, facilitate the action of the coupling agent, and form a hydrophobic and lipophilic structure;

[0072] In the second step, add an appropriate amount of coupling agent into the high-speed mixer, and stir at a high speed of 1500r / min for 5 minutes, and the powder is activated;

[0073] The third step is to add X2, anti-blocking agent and LDPE into the high mixer at the same time, and stir for several minutes; then add X1, X3, carrier resin and reinforcing material, and stir for several minutes at a speed of 1400r / min;

[0074] The fourth step is to put all the materials in the high mixer into the internal mixer, and internally knead through the internal mixer for 8 minutes, shear and dis...

Abstract

The invention provides a novel plastic substitute material capable of being used as a mulching film. The novel plastic substitute material is composed of 20-51% of inorganic powder, 1-3% of an anti-blocking agent, 1-10% of a coupling agent, 3-10% of LDPE, 5-20% of carrier resin, 4-20% of a reinforcing material, 1-10% of X1, 1-10% of X2 and 1-10% of X3. The mulching film prepared from the materialhas the advantages of heat preservation, moisture preservation, freezing prevention, insect prevention, disease resistance, weeding, ventilation, fertilization, high efficiency, environmental protection, soil loss prevention, soil hardening improvement and the like. The prepared polyethylene blow-molded agricultural ground covering film has the thickness of 1 or 1.2 filaments, the appearance (uniform color and luster and no obvious holes or bubbles), the mechanical property (the tensile load is greater than or equal to 5.0 N and the breaking strain is greater than or equal to 400%), the weather resistance (stable chemical properties after long-time exposure), the thickness deviation (the thickness limit deviation is less than or equal to 0.005 mm), the width limit deviation (the limit deviation is less than or equal to 10 mm within the width range of 800-1500 mm), the net mass limit deviation (when the mass of each roll is less than or equal to 10 kg, the limit deviation is less than or equal to 0.10 kg) and the like meet the GB / T13735-2017 standard. Meanwhile, the biodegradable period of the plastic substitute material is short, and the plastic substitute material is environment-friendly.

Description

technical field [0001] The invention relates to a new plastic material, in particular to a new plastic-substituting material and a preparation process, and more specifically, to a new plastic-substituting material that can be used as a mulch film and a preparation process thereof. Background technique [0002] Covering the surface with plastic film has the functions of increasing temperature, early maturity, increasing yield, preventing soil water flow, and controlling soil salinity. It is widely used in arid and semi-arid areas in the north and has become an important agricultural production increase technology. However, since the mulch currently used is basically an ordinary plastic mulch, its raw material is mainly polyethylene, which has a large molecular weight and stable performance. It is difficult to degrade under natural conditions and can remain in the soil for more than a thousand years. With the continuous use of plastic film, more and more residual film in the f...
