Main thermoplastic, especially fiber and long filament, film extrusion, in terms of.The fabulous flowing of polypropylene
The flow velocity and other unique polymer properties of performance and wide scope combine, it is made to have excellent processing performance.It is lower
Flow velocity be able to satisfy the processing request of compressive zone, band-like long filament and monofilament etc., moreover it is possible to so that finished product is had tensile strength and low extensibility,
The case where keeping enough lateral integralities simultaneously, making the splitting and dust from flying on filament winding machine guiding device reaches minimum journey
Degree.Main feature: nontoxic, tasteless, density is small, and intensity, rigidity, hardness heat resistance are superior to low pressure polyethylene, has higher anti-
Bending fatigue strength.But fracture phenomena easily occurs for traditional Polywoven Bag, limits the use of its daily life.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of anti-cracking Polywoven Bags.The present invention has
Excellent anti-cracking performance.
A kind of anti-cracking Polywoven Bag proposed by the present invention, raw material include: 60-75 parts of polyethylene, polyoxy by weight
Change methylene 12-21 parts, 4.5-12.5 parts of anti-cracking agent, 2-6 parts of pla-pcl, 2.5-9 parts of lignin, dimethyl aminoethyl
1-5 parts of ester, 0.5-5.5 parts of deca-BDE, 0.7-1.8 parts of zinc stearate, 1.5-5 parts of clay, 3.5-7.5 parts of antioxidant, three
Aoxidize 1-5 parts of two antimony, 1-3.5 parts of defoaming agent.
Preferably, the anti-cracking agent the preparation method comprises the following steps: take sepiolite, deionized water is added, ultrasonic disperse obtains Hai Pao
Stone dispersion liquid；Under stirring condition, sodium alginate is added into sepiolite dispersion liquid, heats up, continues to be stirred to react, filters, it is dry,
Grinding, obtains anti-cracking agent.
Preferably, the mass ratio of the sepiolite and sodium alginate is 1:0.3-1.4.
Preferably, the power of the ultrasonic disperse is 50-200W, time 25-55min.
Preferably, the temperature being stirred to react is 45-60 DEG C, time 30-65min.
Preferably, the temperature of the drying is 70-85 DEG C, time 20-50min.
Preferably, described to be ground to ground 80-200 mesh.
Preferably, the polyethylene is by medium density polyethylene and low density polyethylene (LDPE) according to the weight ratio group of 1:0.2-1.5
At.
The present invention can be prepared conventionally.
Raw material of the invention includes polyethylene, polyoxymethylenes, anti-cracking agent, pla-pcl, lignin, acrylic acid dimethyl
Amino ethyl ester, deca-BDE, zinc stearate, clay, antioxidant, antimony oxide, defoaming agent, each materials compatibility is good, matches
It can assign the present invention good basic property after cooperation use, in preferred embodiment, in the preparation of anti-cracking agent, selection uses alginic acid
Sodium is modified sepiolite, wherein it is the tubulose connected pathways of 0.36nm × 1.06nm and larger that sepiolite, which has sectional area,
Surface area, and sepiolite octahedral site is rich in a large amount of magnesium ions；Sodium alginate is by beta-D-mannuronic acid (β-D-
Mannuronic, M) and α-L- guluronic acid (α-L-guluronic, G) by (1 → 4) key connection made of；In specific temperature
Under, with the magnesium ion on sepiolite surface ion-exchange reactions can occur for the sodium ion in sodium alginate, and then make seaweed acidic group
Team knowledge enables its surface property change in the surface or channel of sepiolite, is changed into lipophilicity by original hydrophily,
Increase channel cross-sectional area simultaneously, improves dispersibility of the sepiolite between the macromolecule raw materials such as polyethylene, make the present invention to impact energy
The dispersibility and absorbability of amount improve, and cause toughness to increase, and sepiolite can be formed with macromolecule raw materials such as polyethylene
Much larger than the effect of Van der Waals force, while meerschaum particle has stronger rigidity, deflection can be brought it about in crack propagation,
Energy is absorbed, crackle is terminated, plays the effect of toughening, in addition, sodium alginate is when occurring ion-exchange reactions, G unit can
Accumulation forms cross-linked network structure in sepiolite channel, significantly improves the rigidity and toughness of sepiolite, advanced optimizes above-mentioned
Toughening effect, and then make the present invention that there is excellent anti-cracking performance.In addition, the addition of sepiolite can be improved the anti-flammability of invention
Energy.
