Abstract
The invention belongs to the composition of raw materials of plastics.It is by polypropylene, lime carbonate, potter's clay, talcum powder and titanate coupling agent, mixes by a certain percentage.Because the effect of coupling agent has increased the blended amount of mineral filler at the polypropylene base-material, thereby has improved the softening temperature of woven bag, reaches the purpose of packaging temp up to 150 ℃ material.This composition of raw materials technology is simple, need not to increase equipment, has certain social benefit and economic benefit.
Description
The invention belongs to the composition of raw materials of plastics.
Common polypropylene woven bag raw material is by mineral filler blending such as polypropylene base-material and lime carbonate and make.Because the intermiscibility of polypropylene and mineral filler is relatively poor, so the blended amount of mineral filler is less, causes the softening temperature of raw material low, can only be used for the material package below 100 ℃.When needing packing,, can make woven bag softening and cause and to load and transport because temperature of charge, adopts plain polypropylene woven bag packing up to 150 ℃ such as high temperature materials such as soda ash, saltpetre.Therefore have to use bale packing, this not only makes Packing Fee increase, and the stopping property of gunnysack is poor, and the material leakage is serious, easily contaminated material.
The objective of the invention is to obtain that a kind of raw material is easy to get, cheap resistant to elevated temperatures polypropylene woven bag.
Design of the present invention: in base-material polypropylene and mineral filler, add a kind of coupling agent, utilize the chemical action of coupling agent, improve the intermiscibility of polypropylene and mineral filler, increase the blended amount of mineral filler, thereby improve the softening temperature of raw material.
The woven bag raw material of preparing according to above-mentioned design at first need prepare a kind of particle masterbatch, and it is to be cooperated by polypropylene, lime carbonate, talcum powder, potter's clay and titanate coupling agent to form.The weight of each component of particle masterbatch consists of: polypropylene 30～50%, lime carbonate 50～70%, talcum powder 5～20%, potter's clay 5～20%, titanate coupling agent 0.1～2%.Then particle masterbatch and polypropylene base-material are formed fusion with 15～50% and 50～85% weight, And extrudes, cuts apart, is drawn into flat filament through mixing.In constituting material of the present invention, the metatitanic acid coupling agent is single oxygen cyclic group type titanate coupling agent.
The invention provides a kind of resistant to elevated temperatures polypropylene woven bag composition of raw materials, is 150 ℃ high-temperature material but use the polypropylene woven bag packing materials temperature of manufacturing of the present invention, and every technical indicator all meets the requirements, and test result is as follows:
Pull-off force 〉=650N/50mm radially;
Broadwise pull-off force 〉=650N/50mm;
Fall down test 1.2M any direction is bale broken not;
150 ℃ (the highest 165 ℃) repeatedly wrap 24 hours harmless;
170 ℃ wrap without end 24 hours harmless.
Manufacture craft of the present invention is simple, raw material is easy to get, need not to increase new installation and change the flat filament drawing process.Adopt this woven bag suitable with 25～50 kilograms be packaged as, have the intensity height, moistureproofness is good, and material is difficult for advantages such as leakage and pollution, has certain social benefit and economic benefit.
Embodiment: at normal temperatures and pressures, titanate coupling agent 0.1～2% spary in high-speed stirring through exsiccant by lime carbonate 50～70%, talcum powder 5～20%, potter's clay 5～20% blended inorganic materials, after stirring in 5～30 minutes, add polypropylene 30～50%, restir 2 minutes makes compound, carries out granulation through banburying, section, pelletizing.The particle masterbatch that makes formed with 15～50% weight mix the polypropylene base-material, the weight of polypropylene base-material forms 50～85%, through fully mixing, film extrusion, cold cut, cuts apart, stretches, is wound into flat filament.
Claims (2)
1, a kind of raw material that is used to make resistant to elevated temperatures polypropylene woven bag, it is characterized in that having mixed in the polypropylene base-material particle masterbatch of forming by polypropylene, lime carbonate, talcum powder, potter's clay and coupling agent, the weight of masterbatch consists of polypropylene 30～50%, lime carbonate 50～70%, talcum powder 5～20%, potter's clay 5～20%, single oxygen cyclic group type titanate coupling agent 0.1～2%.
2, woven bag raw material according to claim 1, the fusion weight percent that it is characterized in that described particle masterbatch and polypropylene base-material is a particle masterbatch 15～50%, polypropylene 50～85%.
