Abstract
The invention relates to a method for preparing a high filling plastic masterbatch for a polypropylene woven bag. The method includes that inorganic powders with particle sizes of 1250 meshes, such as calcite powders, marble powders or talcum powders, are selected; an active auxiliary with the weight of 1-1.5% of the weight of the inorganic powders is added to the inorganic powders, and the mixture is heated and mixed in a high-speed mixer to coat the active auxiliary on the surface of the inorganic powders; a polypropylene resin with the weight of 5-10% of the weight of the inorganic powders and a polyethylene wax with the weight of 5-10% of the weight of the inorganic powders are added when the material temperature rises to 105-120 DEG C; mixing is continued, and the material temperature continues rising; the polyethylene wax gradually melts and mixed materials are stuck into granules the moment current of the high-speed mixer rises; rotation speeds of the high-speed mixer are adjusted into low speeds at the moment, a discharge valve is opened to discharge the materials, and the materials are cooled and crushed and then conveyed to a double-screw extruder for pelleting to obtain the high filling plastic masterbatch for the polypropylene woven bag. Under same strength of the woven bag, the high filling plastic masterbatch is large in filling amount, surfaces of weave wires are smooth, and production costs of the woven bag are effectively reduced.
Description
Technical field
The present invention relates to the preparation method of a kind of polypropylene woven bag, belong to the filling-modified technical field of plastics with high filled plastics master batch.
Background technology
In the woven bag production process, at first be need a certain amount of filled plastics master batch be joined in the Vestolen PP 7052 to mix, drawwing wire then is made into band, so both can improve hiding rare, the tinctorial yield of silk, also can reduce the cost of woven bag simultaneously.The plastic master batch of in the past filling is owing to exist bad dispersibility, and the defective that diameter of particle is thicker is so join the plastic master batch of filling when mixing in the Vestolen PP 7052; Loading level generally can only add about 25%, and loading level is few, if strengthen loading level again; Will cause the intensity of silk obviously to descend, this common plastics master batch is filled in the lacing simultaneously, the silk surface irregularity; And acrylic resin costs an arm and a leg, and causes the woven bag cost high.
Summary of the invention
The invention discloses the preparation method of a kind of polypropylene woven bag with high filled plastics master batch; Mainly be to existing filled plastics master batch in lacing in bad dispersibility, the master batch inorganic powder and the low defective of acrylic resin bonding force set about studying; Diameter of particle is thick to overcome, loading level is few; Defectives such as braided wires surface irregularity, polypropylene woven bag cost an arm and a leg.The present invention carries out the coupling activation treatment through coupling agent to inorganic powder surface, and the bonding force with enhancing and acrylic resin does not descend thereby reach lacing intensity, and the purpose that the loading level of filler parent granule can increase considerably.Adopt the plastic master batch of the inventive method preparation, not only addition can reach 35%, and braided wires smooth surface light, effectively reduces the production cost of woven bag.
Technical scheme of the present invention is achieved in that
A kind of polypropylene woven bag is characterized in that carrying out according to following steps with the preparation method of high filled plastics master batch:
Selecting particle diameter for use is 1250 orders, wherein 10 μ>97% inorganic powder, add 1～1.5% coagent of relative inorganic powder weight; Heating mixes in high-speed mixer, makes the coagent bag multiple on the surface of inorganic powder, when temperature of charge rises to 105～120 when spending; Add 5～10% acrylic resins of inorganic powder weight and 5～10% polyethylene waxs of inorganic powder weight, continue to mix, temperature of charge continues to rise; When moment that the high-speed mixer electric current raises, polyethylene wax progressively melts, and mixture is sticking agglomerating granular; Open bleeder valve this moment with high-speed mixer rotating speed furnishing at a slow speed, emits material; Cooling, pulverizing are delivered to the twin screw extruder granulation and are promptly obtained polypropylene woven bag with high filled plastics master batch.
Said inorganic powder is a kind of in calcite in powder, marble flour, the talcum powder.
Said coagent is a kind of in metatitanic acid fat, aluminic acid ester, the Triple Pressed Stearic Acid.
The woven bag of the inventive method preparation is used for lacing with high filler parent granule, compares with filled plastics masterbatch in the past, and following characteristics are arranged:
1. loading level is big: under same intensity, common plastics master batch loading level is 25%, and filled plastics master batch of the present invention can be filled to 35%.
2. surface smoothness is good: the common plastics master batch is filled in the lacing, silk surface irregularity, and the present invention's filled plastics master batch, then silk smooth surface light.
3. with the present invention's filled plastics master batch,, replaced the partly expensive acrylic resin of value, thereby reduced the production cost of woven bag because loading level increases.
Embodiment
Below in conjunction with embodiment the present invention is elaborated.
Embodiment 1
Water intaking divides calcite in powder (water-ground limestone) 100Kg less than 0.1%, and its particle diameter of 97% places high-speed mixer less than 10 μ; The aluminic acid ester that adds 1.5Kg carries out mixed at high speed, 120 adds the 8Kg acrylic resin when spending when temperature of charge is increased to, polyethylene wax 7Kg continues mixed at high speed, when moment of high-speed mixer electric current rising; Show that material begins to form the clay shape; Open bleeder valve this moment with high-speed mixer rotating speed furnishing at a slow speed, emits material; Cooling, pulverize, deliver to the twin screw extruder granulation.
Embodiment 2
Marble flour: method is the same
Embodiment 3
Talcum powder: method is the same
Below in conjunction with embodiment the present invention's used material addition span of control and mixing temperature condition are explained.
1, the scope of coagent add-on control:
The coagent add-on is not less than 1% of relative inorganic powder weight, otherwise can make the coverage degree of powder inadequately, causes the activity of powder to descend.If be higher than 1.5%, because coverage degree is excessive, cause the adhesion between the particle easily, be difficult for disperseing.
2, the scope of acrylic resin add-on control:
The acrylic resin add-on is not less than 5% of relative inorganic powder weight, otherwise the intensity of product and dispersiveness are all relatively poor, if be higher than 10%, the cost of manufacture of masterbatch improves relatively.
3, the scope of polyethylene wax add-on control:
The polyethylene wax add-on is not less than 5% of relative inorganic powder weight, otherwise is unfavorable for the granulating that bonds, if be higher than 10%, cost of manufacture improves, and also can cause product strength to descend.
