Abstract
The invention relates to a kind of plastic filler parent granule of high dispersive type, this filler parent granule can not only not reduce the physical and mechanical properties of former plastics under bigger loading level, and its processing characteristics and physical and mechanical properties are increased substantially, so both reduced the plastics cost, improved its quality again.This filler parent granule as matrix, through auxiliary agent surface treatments such as chelating type phthalates, and is a carrier with petroleum resin, ethylene-propylene rubber(EPR), low-molecular-weight resin, dispersion agent, waste and old recovery polyolefin blend body by lime carbonate, forms through mixing, in blocks, pelletizing.
Description
The invention relates to a kind of plastic filler parent granule of high dispersive type.
Filler for plastic was with Atactic Polypropelene particle and fleut in the past, the Atactic Polypropelene raw material is in great shortage, almost exhausted, fleut generally is to be formed through surface treatment by mineral fillers such as lime carbonate, mica, talcum powder, must increase granulating working procedure, and this filler dispersion is poor, fills inhomogeneous.General weighting agent loading level is low, once loading level raises slightly, will cause the reduction of the physical and mechanical properties of plastics, thereby influence the quality of plastics.
The objective of the invention is to develop a kind of filler for plastic of granulous good dispersity, this cheap weighting agent is under the situation of big loading level, not only do not reduce the physical and mechanical properties of former plastics, and its processing characteristics and physical and mechanical properties are increased substantially, reduce the plastics cost to reach, improve the purpose of its quality again.
Plastic filler parent granule of the present invention is that the mixture with petroleum resin, increasing component, dispersion agent, waste and old recovery polyolefine material is a carrier, and mineral filler forms with carrier is mixing after surface treatment agent is handled, and its proportioning is as follows:
Composition %(weight)
Carrier
Petroleum resin 5～20
Increasing component 2～10
Dispersion agent 5～20
Waste polyolefine 5～15
Mineral filler
Surface-treated agent
Coupling agent 0.7～1.5
Linking agent 0.2
Softening agent 0.8～2
Lubricant 0.2～2
The increasing component that uses in the above-mentioned carrier can be ethylene-propylene rubber(EPR), styrene-butadiene rubber(SBR), isoprene-isobutylene rubber, ethylene-vinyl acetate copolymer (EVA), various plastics elastic body.Dispersion agent can be the low-molecular-weight resin class, for example: ethylene waxes, ethene oil, low molecular weight polycaprolactone benzene, low molecular weight polycaprolactone ester.The coupling agent that uses in the above-mentioned filler treatment agent can be a phthalate, and is wherein best with the chelating type phthalate; Linking agent can be used organo-peroxide class, amine, and is best with bismaleimides; Softening agent can be clorafin, phthalate, aromatic hydrocarbon phosphoric acid ester; Lubricant can be hard ester acid or calcium stearate.
Filler parent granule preparation method of the present invention carries out surface treatment with mineral filler earlier, promptly under 90～95 ℃ mineral filler, coupling agent, linking agent, lubricant, plasticizer materials being mediated in the high speed kneader 10～15 minutes, till cannot not mixing heavyly in the cold water.The preparation method of carrier got final product petroleum resin, waste polyolefine, dispersion agent and increasing component in 10 minutes at 160～170 ℃ of following melt compounding.The mineral filler that to handle and carrier are product 90～100 ℃ of down mixing, in blocks, pelletizings then.
The advantage of filler parent granule of the present invention is owing to adopt the mixture that constitutes with petroleum resin, dispersion agent, increasing component, waste and old recovery polyolefine material as carrier, so have good dispersing property, mineral filler is easy to various mixed with polymers even after surface treatment again, avoided the agglomeration of filler, so easy to use, work simplification.This filler parent granule consistency is good, uses extensively, can be used for plastics such as filled polyethylene, polypropylene, polyvinyl chloride.This filler parent granule has the synergy and the combined effect of many auxiliary agents, and good fluidity, to be easy to moulding, improves output; Can also use big loading level, when reducing the plastics cost significantly, improve the physical and mechanical properties of its goods.For example the polypropylene strap of 16mm on the basis that does not change technology, equipment, is dosed 20%(weight) behind this kind filler parent granule, good dispersion is extruded stablely, per tonly reduce cost 600 yuan, and quality of item increases, and sees the following form:
| Project | Unit | The standard laid down by the ministries or commissions of the Central Government | Actual measurement |
| Nonstraightness | Deflection mm/ rice | ＜30 | 14 |
| Tensile strength | kg/cm 2 | ＞160 | 329 |
| Unit elongation | ％ | ＜25 | 17 |
Behind the filler parent granule of the present invention and for example: high-pressure polyethylene (LDPE) pipe, on the basis that does not change technology, equipment, fill 20%(weight), dispersion flows is good, and moulding is easy, improves 10% with rotating speed output, and product properties is as follows:
| Project | Unit | The standard laid down by the ministries or commissions of the Central Government | Actual measurement |
| Tensile strength | kg/cm 2 | ≥80 | 97.9 |
| The hydrostatic control test | kg/cm 2 | Pressurize qualified 32.3 is broken |
Embodiment:
Filling surface is handled and prescription:
Form %(weight)
Water-ground limestone (380～400 order) 25
Light calcium carbonate (130 order) 45
Chelating type phthalate 0.8
Bismaleimides 0.2
Clorafin 0.8
Hard ester acid 0.2
Above-mentioned each component under 90～95 ℃, is mediated in kneader 500 rev/mins speed and to be got final product in 10～15 minutes.
The preparation of carrier and proportioning:
Form %(weight)
High softening-point petroleum resin 5
(softening temperature＞120 ℃)
Ethylene-propylene rubber(EPR) 2
Ethylene waxes 10
Ethene oil 2
Waste polyethylene 9
Above-mentioned each component was got final product in 160～170 ℃ of following melt compounding in 10 minutes.
The mineral filler that to handle and carrier are product in 90～100 ℃ of down mixing, in blocks, pelletizings then.This good product dispersibility does not produce agglomeration, good product mobility.
