Embodiment 1

[0050] 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 100°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;

[0051] 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;

[0052] 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;

[0053] The fourth step is to put all the materials in the high mixer into the internal mixer, and internally knead for 10 minutes through the internal mixer. After the m...

Embodiment 2

[0061] 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 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;

[0062] In the second step, add an appropriate amount of coupling agent into the high-speed mixer, and stir at a high speed of 1200r / min for 5 minutes, and the powder is activated;

[0063] 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;

[0064] The fourth step is to put all the materials in the high mixer into the internal mixer, and internally knead for 8 minutes through the internal mixer. After the ma...

Embodiment 3

[0072] The first step is to put the inorganic powder into the high-speed mixer first, and stir at a high speed of 1400r / 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;

[0073] 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;

[0074] 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 1500r / min;

Abstract

The invention provides a novel plastic substitute material capable of being used as a film bag. The novel plastic substitute material comprises 15-51% of inorganic powder, 1-3% of an anti-blocking agent, 2-10% of a coupling agent, 3-10% of LDPE, 5-20% of carrier resin, 5-20% of a reinforcing material, 1-10% of X1, 1-10% of X2 and 1-10% of X3. The novel plastic substitute material prepared by the invention can be used as an express bag, a garbage bag and a shopping bag, and aims to solve the problem of white garbage. According to the express bag, the garbage bag and the shopping bag prepared bythe invention, the mechanical properties (the bearing capacity of 10 liters of standard plastic bag can reach 20kg) are good, and the heat sealing effect is good, so that the use national standards GB / T16606.3-2009, GB / T24454-2009 and GB / T21661-2008 of the express bag, the garbage bag and the shopping bag are respectively met. And meanwhile, the plastic substitute material is short in biodegradation period and 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, more specifically, to a new plastic-substituting material that can be used as express bags, garbage bags, and shopping bags and its preparation process. Background technique [0002] Plastic products, especially disposable plastic bags, such as garbage courier bags, garbage bags, shopping bags and garbage bags, bring convenience, speed, practicality and efficiency to human life, but also cause white pollution to the environment. Inorganic powder modified environmentally friendly plastics have emerged as a class of environmentally friendly materials to deal with the problem of white garbage. On the one hand, there are a large number of plastic filler masterbatches on the market. Although the powder content can reach 75-85%, it needs to be added to the polyethylene resin at a ratio of 15-35%. After mixing evenly, the film can b...
