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 with high filled plastics master batch, belong to filling plastic modification technology field.
Background technology
In woven bag production process, be first a certain amount of filled plastics master batch need to be joined in polypropylene and mixes, then draw wire and be 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 existing bad dispersibility, the defect that diameter of particle is thicker, so the plastic master batch of filling is joined while mixing in polypropylene, and loading level generally can only add 25% left and right, loading level is few, if strengthen again loading level, will cause the intensity of silk obviously to decline, this common plastics master batch is filled in lacing simultaneously, silk surface irregularity, and acrylic resin is expensive, cause 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, be mainly for existing filled plastics master batch in lacing in bad dispersibility, master batch inorganic powder and the low defect of acrylic resin bonding force set about studying, with overcome diameter of particle compared with thick, loading level is few, braided wires surface irregularity, the defect such as polypropylene woven bag is expensive.The present invention carries out coupling activation treatment by coupling agent to inorganic powder surface, to strengthen and the bonding force of acrylic resin, do not decline thereby reach lacing intensity, and the object that the loading level of filler parent granule can increase considerably.The plastic master batch that adopts the inventive method to prepare, not only addition can reach 35%, and braided wires smooth surface light, effectively reduces the production cost of woven bag.
Technical solution of the present invention is achieved in that
A preparation method for high filled plastics master batch for polypropylene woven bag, is characterized in that carrying out in accordance with the following steps:
Selecting particle diameter is 1250 orders, the wherein inorganic powder of 10 μ m>97%, add 1～1.5% coagent of relative inorganic powder weight, in high-speed mixer, heating mixes, make the surface of coagent cladding at inorganic powder, when temperature of charge rises to 105～120 while 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 high-speed mixer electric current raise moment time, polyethylene wax progressively melts, mixture sticks into a shape, now by high-speed mixer rotating speed furnishing at a slow speed, open bleeder valve, emit material, cooling, pulverize, deliver to twin screw extruder granulation and obtain high filled plastics master batch for polypropylene woven bag.
Described inorganic powder is the one in calcite in powder, marble flour, talcum powder.
Described coagent is the one in metatitanic acid fat, Aluminate, stearic acid.
Woven bag prepared by the inventive method for lacing, compared with filled plastics masterbatch in the past, has following characteristics with high filler parent granule:
1. loading level is large: 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: common plastics master batch is filled in lacing, silk surface irregularity, and the present invention's filled plastics master batch, silk smooth surface light.
3. with the present invention's filled plastics master batch, because loading level increases, replaced part and be worth expensive acrylic resin, thereby reduced the production cost of woven bag.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
Embodiment 1
Water intaking point is less than 0.1% calcite in powder (water-ground limestone) 100Kg, its particle diameter of 97% is less than 10 μ m, be placed in high-speed mixer, add the Aluminate of 1.5Kg to carry out high-speed mixing, when being increased to 120, temperature of charge add 8Kg acrylic resin, polyethylene wax 7Kg to continue high-speed mixing while spending, when high-speed mixer electric current raise moment time, show that material starts to form clay shape, now by high-speed mixer rotating speed furnishing at a slow speed, open bleeder valve, emit material, cooling, pulverize, deliver to 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 material addition used span of control and mixing temperature condition are explained.
1, the scope control of coagent add-on:
Coagent add-on is not less than 1% of relative inorganic powder weight, otherwise can make the coverage degree of powder inadequate, cause powder activity decline.If higher than 1.5%, because coverage degree is excessive, easily cause the adhesion between particle, be difficult for disperseing.
2, the scope control of acrylic resin add-on:
Acrylic resin add-on is not less than 5% of relative inorganic powder weight, otherwise the intensity of product and dispersiveness are all poor, if higher than 10%, the cost of manufacture of masterbatch improves relatively.
3, the scope control of polyethylene wax add-on:
Polyethylene wax add-on is not less than 5% of relative inorganic powder weight, otherwise is unfavorable for the granulating that bonds, if higher than 10%, cost of manufacture improves, and also can cause product strength to decline.
4, the temperature range in mixing of materials process:
Material is in high-speed mixing process, and temperature of charge can rise, in the time that temperature arrival 105～120 is spent, the acrylic resin, the polyethylene wax that add start progressively melting, mixture sticks into a shape, and high-speed mixer rotating speed furnishing at a slow speed, declines after temperature of charge raises.
