Abstract
The present invention relates to a toughening master batch for nano calcium carbonate plastics, which belongs to a master batch prepared from nano calcium carbonate, auxiliary agent and carrier resin which are blended. The present invention comprises components (weight percentage): 50 to 80 of nano calcium carbonate, 10 to 30 of low molecular weight polystyrene, 2 to 11 of other auxiliary agent and 8 to 30 of carrier resin. The present invention can enable the nano calcium carbonate to be uniformly distributed in base plastics to improve the shock resistance of the material, and is suitable for the moulding of plastics, such as polyvinyl chloride, polypropylene, polyamide, polyethylene or acrylonitrile-butadiene-styrene copolymer.
Description
The present invention relates to a kind of masterbatch of making of nanometer grade calcium carbonate, auxiliary agent and vector resin blend, because having added low-molecular-weight polystyrene in masterbatch plays dissemination, nano-calcium carbonate can be evenly dispersed in the matrix plastic, to improve the shock resistance of material.
In order to reduce the cost of material, lime carbonate is directly joined in the plastics as filler with powder type, this performance to material has tangible reduction effect.In order to improve the performance of material, after making master batch, adds to again in the plastics by the auxiliary agent that has added dissemination in lime carbonate, and the problem that material property is reduced is improved.Applying nano level lime carbonate has special " surface effects ", " volume effect " and " quantum effect " in recent years, nanometer grade calcium carbonate is filled in the plastics, to improving the good action that has of material property.At " nano level CaCO
3Particle is to the toughness reinforcing enhancing of PVC research " reported in (Chinese plastics, the 13rd the 6th phase of volume, in June, 1999) literary composition and used 30nm CaCO
3In filled PVC/ACR co-mixing system, the result shows that inorganic nano-particle dispersion situation directly influences the performance of material, nano level CaCO
3Consumption 5%～10% is advisable.The notched Izod impact strength maximum value is 24KJ/m when adopting the nano-calcium carbonate 5% of median size 30nm
2, surpass or when being lower than 5% consumption, notched Izod impact strength but descends significantly.Because this method is to adopt general auxiliary agent and nano-calcium carbonate directly to join in the plastic matrix material, therefore can influence the dispersiveness of nano-calcium carbonate in body material, thereby have influence on the further raising of the mechanical property of material.
The objective of the invention is to propose a kind ofly can improve nano-calcium carbonate dispersed masterbatch that plays toughening effect in plastics.Nano-calcium carbonate can be dispersed in the plastics, can improve the mechanical property (particularly shock resistance) of matrix material effectively.
General calcium carbonate plastics masterbatch is made up of lime carbonate, auxiliary agent (stearic acid or stearate and macromolecule wax) and vector resin.The toughness reinforced mother material for nanometer calcium carbonate plastics that the present invention proposes, lime carbonate is that particle diameter is the nanometer grade calcium carbonate of 5～50nm in its component; Except that the auxiliary agent of common usefulness, also be added with low-molecular-weight polystyrene; Each component (weight %) is a nano-calcium carbonate: 50～80; Low-molecular-weight polystyrene: 10～30; Other auxiliary agent: 2～11; Vector resin: 8～30.The molecular weight of low-molecular-weight polystyrene is 1000～10000.Vector resin is: polyvinyl chloride, new LDPE (film grade) or polymeric amide.
In toughness reinforced mother material for nanometer calcium carbonate plastics component provided by the invention, when the particle diameter of nano-calcium carbonate was excessive, the feature of " nano effect " was not obvious; The too small preparation difficulty of particle diameter.In being prepared, masterbatch has any problem when the nano-calcium carbonate amount that adds is too much; Be unfavorable for applying because of the cost increase when very few.It is too high that the low-molecular-weight polystyrene amount can make cost increase for a long time, do not reach basic toughening effect when very few again.The molecular weight of low-molecular-weight polystyrene is conventional scope.Other used auxiliary agent all is know altogether common at the used auxiliary agent of calcium carbonate-filled plastics blend, for example: stearic acid, Zinic stearas and oxidic polyethylene or polyethylene etc.
Prepare the blend working method of toughness reinforced mother material for nanometer calcium carbonate plastics of the present invention according to routine, nano-calcium carbonate, low-molecular-weight polystyrene, other auxiliary agent and vector resin are processed in mixing facilities, and the mixing facilities that is adopted has: single (two) screw extrusion press or close (opening) refining machine and granulating equipment.
The present invention is because the lime carbonate particle diameter that adopts is 5～50nm, and this nanometer grade calcium carbonate helps improving the infill system mechanical property; And adopted dispersing low-molecular-weight polystyrene, make Nano particles of calcium carbonate can be dispersed in the vector resin, give full play to its toughening effect, low-molecular-weight polystyrene is a kind of rigidity plastics in addition, itself also has toughening effect, so its toughness reinforcing effect of their combined action is just more obvious.Toughness reinforced mother material for nanometer calcium carbonate plastics of the present invention and being used in the forming process of plastics can make nano-calcium carbonate be dispersed in the matrix plastic, improves the performance of material.When vector resin of the present invention is that can be used for matrix plastic be the toughness reinforcing of polyvinyl chloride for masterbatch that polyvinyl chloride obtains when counting.It is polyacrylic toughness reinforcing that the masterbatch that the vector resin of using as the present invention obtains during for new LDPE (film grade) can be used for matrix plastic.When the toughness reinforced mother material for nanometer calcium carbonate plastics that obtains with the embodiment of the invention 1 is used for the pvc material forming process, when the parts by weight of masterbatch and matrix plastic polyvinyl chloride were 10: 100, the notched Izod impact strength of resulting PVC/CPE (the CPE parts by weight are 10) matrix material reached 30KJ/m
2When the parts by weight of masterbatch and polyvinyl chloride were 20: 100, the notched Izod impact strength of resulting PVC/CPE (the CPE parts by weight are 10) matrix material reached 45KJ/m
2Show in the scope of nano-calcium carbonate consumption all can reach high impulse strength, help industrial applications at broad.Show that from Fracture Profile in Metallic Materials transmission electron microscope detected result nano-calcium carbonate is uniformly dispersed matrix plastic, be not the cluster state of aggregation, so toughening effect is obvious.Prior art be directly add nano-calcium carbonate then be the cluster state of aggregation.Toughness reinforced mother material for nanometer calcium carbonate plastics provided by the invention is suitable for the toughness reinforcing of polyvinyl chloride, polypropylene, polymeric amide, polyethylene or ABS plastics such as (acrylonitrile-butadiene-styrene copolymers), is used for the forming process of plastics.
