Abstract
The invention provides a manufacturing method of a weight-increase-free cost-reduced master batch. The master batch is prepared from an organic powder through the following three steps: 1) wood powder treatment: wood powder contains a large amount of hydroxyl functional group, so that the wood powder is coated by epoxidized soybean oil as a treatment agent to complete the wood powder treatment; 2) preparation of a pre-modified material: 70% of the wood powder (200 meshes), 3% of the epoxidized soybean oil and 27% of EVA powder are mixed in a high-speed mixer; and 3) polyethylene and polypropylene are added to the pre-modified material, and the weight-increase-free cost-reduced master batch can be produced just by heating the prepared mixture.
Description
Background of invention: add inorganic particle to plastics and can drop plastics cost, save the manufacture plastic raw materials energy,
It has long been known to, adding technique customary.But, the density of all of inorganic particle that we see
All much bigger than plastics, add the weightening finish of powder body the most composites the most, add the polyethylene of the powder body of 30%
Or polypropylene, removing the increase factor of composite weight, the reduction cost finally given is little.Because,
The true density of inorganic particle usual big 2～3 times than plastics, some blanc fixes bigger than polyethylene or polypropylene five
The most.If powder body inserts plastics, powder particle is in close contact with plastic pellet, if do not had in composite
If having space, then the difference on both particle volumes just influences whether the area of composite product,
During as produced sheet material, composite is weight as pure moulding, and composite produces the area of sheet material will be reduced；
Producing tubing, composite is weight as pure moulding, and the length of the tubing that composite produces is the shortest；Produce
Injection-molded item, composite is weight as pure moulding, and the goods that composite produces are the fewest；Production plastics drop
Solving meal to close, composite is weight with pure moulding as, the pure plastics of meal composition and division in a proportion much heavier of composite production,
Therefore price is than pure plastics more expensive.
Brief summary of the invention: the present invention " do not increase weight cost declining masterbatch " is to use Organic substance powder body to manufacture masterbatch, as
Wood powder, needle pinaster wood powder unit weight 0.371～0.416, Pinus koraiensis unit weight 0.440, larch unit weight 0.641～
0.563, powdered rice hulls unit weight 1～1.1, these are common at nature, be also that yield is big.Use wood
Powder makes the masterbatch containing wood powder powder 70%, masterbatch proportion ＜ 1.0；Powdered rice hulls is used to make containing powdered rice hulls 70%
Masterbatch, masterbatch proportion about 1.0.But, wood powder, powdered rice hulls all contain hydroxy functional group, belong to strong pole
Property polymer, polyethylene, polypropylene are the most incompatible, only have certain compatibility with polyvinyl alcohol in plastics.
Therefore, ignore combination property, if the best performance, here it is the Wood-plastic material of prior art,
But there is a lot of shortcoming.
Want to make the wood powder can be easy as inorganic particle calcium carbonate, simply toward in plastic polyethylene, polypropylene
Calais adds, and key technology is to process wood powder.
1, wood powder treatment technology:
Wood powder 200 mesh, the problem the most do not reunited, need not open agglomerated particles；Wood powder oil absorption is
100g/100g (self test data)；Wood powder contains great amount of hydroxy group Guan Nengtuan.Therefore epoxy soybean oil is selected to process
Agent, in order to be coated with wood powder.
Epoxy soybean oil contains epoxy radicalsCarboxyl (-COOH), molecular formula:
Two kinds of literary styles of epoxy soybean oil molecular structural formula
Epoxy radicals and polyethylene, polypropylene have the compatibility, and carboxyl is active with the hydroxyl reaction in wood powder, generate ester,
So the another name of epoxy soybean oil ' fatty acid glyceryl ester '.Epoxy soybean oil is liquid, adds the 3% of wood powder
(weight number), mixes 15 minutes at a high speed in the most mixed device, can be coated with wood powder, complete wood powder treatment technology.
2, manufacture and give modified materials technology:
Wood powder masterbatch (not being Wood-plastic material) is the best production, the most at home and abroad yet there are no production
The report of wood powder masterbatch.Wood powder oil absorption is big (oil absorption 100), and polarity is very strong, except polyethylene in plastics
Outside alcohol matches with it, other plastics all can not be coated with it.Polyethylene, polypropylene more can not be wrapped by.It is exactly
Say that this process can not be carried out.
The second law of thermodynamics of change in process condition between reaction universe:
PV=Δ U-Δ F-T Δ S
PV represents process
T Δ S absolute temperature T and the product of Entropy Changes Δ S, entropy is system
Dispatcher, Δ S ＞ 0 system absorb heat, Δ S ＜ 0 is
System heat release.
The change of energy in Δ U table, U is the cashier of system, and Δ U is
Timing, table+Δ U is draw heat, when Δ U is negative,
Table-Δ U is exothermic
The change of Δ F table process free energy.Δ F=Δ U-PV-T Δ S.
When Δ F ＜ 0 is negative, process is carried out automatically；When Δ F=0 is zero, process reaches to balance and does not carry out；Δ F ＞ 0
During more than zero, process is carried out round about.We want process and automatically carry out it is necessary to it is negative for making Δ F.
Pre-modified materials is manufactured by second law of thermodynamics formula-Δ F=-Δ U+PV+T Δ S.Wherein-Δ U is negative, mistake
Journey is heat release.Δ S ＜ 0 system heat release.
We reconcile this process and carry out in super mixer, and it is negative for allowing process heat release, i.e.-Δ U.
Formula: wood powder (200 mesh) 70%, epoxy soybean oil 3%, EVA powder 27%.
First wood powder and epoxy soybean oil are put into super mixer, mixed at high speed 15 minutes, completes the powder of the first step
Body processes.Then all material is put into full super mixer, carries out mixed at high speed, will until process heat release
EVA powder is melted to be coated with powder body.Complete the manufacture giving modified materials.Give modified materials with this and make masterbatch, claim ' to give
Modified materials masterbatch ', can at will add in polyethylene, polypropylene, pelletize is extremely easy, has both made at single screw rod
Pelletize unit, also can the most successfully pelletize.
3, give modified materials masterbatch and add polyethylene, polypropylene, meet second law of thermodynamics formula:
PV=Δ U-Δ F-T Δ S Δ S ＞ 0
System is absorbed heat, as long as heating, process can be carried out.
Machinery heating, manufactures plastic by twin-screw set, single-screw machine group.
The performance of each component and effect in formula:
Wood powder: the present invention uses needle pinaster wood powder (unit weight 0.371～0.416), Pinus koraiensis powder (unit weight
0.440), fallen leaves loose powder (unit weight 0.641～0.563), powdered rice hulls (unit weight 1～1.1).All contain a large amount of
Hydroxy functional group, belongs to highly polar polymer；Chemical composition protein content 13%, therefore adds plastics
Its aesthetic appearance of goods can be improved, as protein plastics is used for making button；Oil absorption 100g/100g (self test data)；
Wood powder maximum operation (service) temperature, up to 200 DEG C, therefore adds plastics and is remarkably improved the heat distortion temperature of plastics；Inhale
Tide 20%, therefore wood powder to be dried before use；PH value 5, acid.
Epoxy soybean oil: proportion 0.985～0.990；Epoxide numberEpoxidation be from
Alkene direct oxidation gets, and oxirane is also known as oxidic polyethylene, good with polyethylene compatible, reaction
Property is strong；I.e. every gram, acid number≤0.5 (mgKOH/g) epoxy soybean oil needs the KOH with 0.5 milligram containing acid
Neutralizing, 1000g just has the acid number of 0.5 gram, it is sufficient to protect just with the affinity of wood powder.
EVA powder: EVA is ethylene-vinyl acetate copolymer, is the copolymerization of apolar substance and polar substances
Thing, is therefore added in mixture it and can play the effect of increase-volume；It is random copolymer, flexible, makes it
