Obvious economic benefit and social benefit.
Generally powder body material is used as filler in granular form.The shape of particle is not very regular, but to plastics
For performance, the geometry of filler particles has important impact to the physical and mechanical property for filling system, therefore powder material
The grain shape of material be when using firstly the need of being paid close attention to.For sheet-like particle, often using concept, the i.e. piece of radius-thickness ratio
The planar dimension (vertical or horizontal) of shape particle and the ratio of thickness;For fibrous particle, often using the general of draw ratio
Read, i.e. the length-to-diameter of fibrous particle.The grain shape of calcium carbonate mostly in tetragonal body, hexahedron, many cubes and
Irregular square graininess, physical property impact of its shape on mobility and product in plastic processing are extremely important.This
By precisely screening, we are 6 from draw ratio for invention:1-13:The transparent calcite calcium carbonate of 1 needle-like, fibrous particle
Structure can improve material property further with certain orientation in the plastic deformation of plastics macromolecular structure, while
Again will not be because of the mobile performance of too big draw ratio impact material.
Filling-modified technology it is important that, powder granule is singly distributed to plastics equably, as far as possible
In matrix, it is, in general, that the particle diameter of filler particles is less, if can be uniformly dispersed, then the mechanical property of filling system is better;
But particle diameter is less, processing cost is higher, realizes which dispersed more difficult.Require that the particle diameter distribution of calcium powder is got in plastic products
Narrow better, that is, minimum grain size and maximum particle diameter is classified out, according to use requirement, for different product, present invention collection particle diameter exists
Product in the range of 1000 mesh to 3000 mesh, it is ensured that dispersed, the transparent, mechanical property of product and oil absorbency.
Filler particles surface roughness is different.The particle of i.e. same volume, its surface area geometric form not only with particle
Shape relevant (spherical watch area is minimum), also relevant with the degree of roughness on its surface.Specific surface area is the surface of unit mass filler
Product, its size have direct relation to the compatibility between filler and resin, the difficulty or ease of filler surface activation process and cost.
Filler particles surface free energy magnitude relationship scattered difficulty or ease in matrix resin to filler.When one timing of specific surface area, surface
Free energy is big, particle easier cohesion each other, is more difficult dispersion.When filler is surface-treated, reduce its surface free energy
It is one of main target.By the present invention in that with the dispersant of independent development, choosing multiple efficient couplings effectively for calcium powder
Agent, allows they and inorganic particle mixed at high speed at a certain temperature, in the presence of heat in ambient temperature and friction, reduces powder
The surface free energy of body particle, the polar group of coupling agent is connected to powder granule surface, and non-polar group outwardly, makes powder
Between powder, all there is non-polar group segment to intercept, be difficult to reunite between powder granule, while activation effect is improved, strengthen powder
Compatibility between body and resin macromolecule.
It is relevant that the density of filler piles up state with filler particles.As the particle of precipitated calcium carbonate assumes spindle, and weigh
There is space in broken stone shape when piling up between particle in the particle of matter calcium carbonate, and after the former volume is significantly greater than
Person, thus the apparent density of precipitated calcium carbonate is less than powdered whiting, but this is not intended to fine particle calcium carbonate " light ", coarse whiting " weight ", because
It is that difference for its individual particle between them is very little, the former is 2.4～2.7g/cm3, the latter is 2.7～2.9g/
cm3.In filling plastic modification field, real impact filling system global density be the density of filler individual particle and they
Whether the existence form in plastic substrate is agglomerated together, and has tight etc. and matrix plastic molecule between.This
Weight calcium powder is used in mixed way by invention, is effectively reduced the sedimentation phenomenon in product activation process, is improved activation efficiency.After activation with
Vector resin（According to different product needed）Polypropylene, polyethylene, ethylene-vinyl acetate copolymer, POE,
Ethylene acrylic acid co polymer, lubricant, antioxidant etc. are put in the kneader with S type blade simultaneously and carry out banburying mixing,
Temperature control is at 90-150 DEG C.Under temperature, pressure collective effect, the auxiliary agent such as dispersant, lubricant, coupling agent fully reacts,
The resin carrier allowed under powder granule and elastomeric state uniformly mixed be incorporated in Van der Waals force in the presence of make activation powder surface another
The lipophilic group at end adsorbs on the side chain of resin carrier, as the fibrous rigid structural support of inorganic particle itself lives to set
The long-chain of fat, forms certain space so that PPM environment-friendly materials can't substantially increase the density of product.Reduce becoming for product
This, improves the market competitiveness.
The hardness of filler particles itself has duality, and the high filler of one side hardness can make the resistance to of filled plastics material
Mill property is improved, and on the other hand due to adding filler, the especially high filler of hardness, obturator system are easily right in process
Heavy wear is caused on the surface of the process equipment contacted by material and mould, and during this serious wear, the economic loss that brings
Considerably beyond the interests that brings using filler, the application in the plastic of this powder body material will be affected.Certainly, hardness level is not
Same filler is different to the abrasion of process equipment, on the other hand for the filler of certain hardness, the metal watch of process equipment
The tear strength in face rises with the increase of packing material size, and to after certain particle diameter, its tear strength tends towards stability.Additionally, relative grind
The difference of the hardness of the bi-material of mill is also relevant with tear strength size.When metal strength is higher than 1.25 times of abrasive hardness, category
In low abrasion situation;When metal strength is 0.8～1.25 times of abrasive hardness, belong to middle abrasion condition;Metal strength is less than
During 0.8 times of abrasive hardness, belong to high abrasion condition.For example, it is generally used for the barrel of plastic extruder and the metal material of screw rod
Expect for 38CrMoAl steel alloy, via nitride is processed, its Vickers hardness is 800～900, and the Vickers hardness of coarse whiting is 140 or so.
Therefore the extrusion machining of calcium carbonate filled plastics, despite abrasion, but not particularly significant, can receive at least;And flyash
Glass microballoon or quartz sand, more than 1000, these material filled plastics are extremely serious to the abrasion of nitrated steel for its Vickers hardness,
After tens tons of materials of processing, just there is no (nitration case about 0.4mm is thick) in the nitration case of its screw rod.The present invention is by activation
The calcium carbonate powder of changed handling, reduces the reunion of calcium carbonate granule, improves mobility, reduces pressure when processing,
While plus the parcel of resin carrier, reducing directly contact of the inorganic particle to equipment, product hardness, wearability is being improved
While effectively reducing the abrasion of the equipment of material.
The whiteness height of filler has vital impact to the color and luster or even outward appearance of filled plastics material and product.Logical
Chang Baidu is higher, and the impact to filled plastics coloring is less, only affects the bright-coloured degree of color.Due to there is presently no completely
Transparent filler, therefore filled plastics are often opaque, if the Color whiteness of filler is not high or be in other color and lusters, only
The plastic products of black or dark color can be done.Plastic material itself has very big difference, the folding of most general-purpose plastics to the refractive index of light
Rate is penetrated 1.50～1.60.When the refractive index of powder stuffing and the refractive index of plastic substrate same or like when, they are added to
Covering impact after in matrix plastic on light is less, otherwise filled plastics are just strong to the covering effect of light.The present invention chooses high
Calcite is originated as calcium carbonate powder thoroughly, and whiteness is high.While calcite crystal has two equal short axles and perpendicular to the 3rd
Axle (major axis).Light along major axis propagate when, its spread speed is indeclinable, and when light is propagated along other directions, is divided
The light for two kinds of friction speeds is solved, produces two refractive indexes.Two refractive indexes of calcite be respectively 1.658 and 1.486 with
The refractive index 1.50～1.60 of general-purpose plastics is close to, and the product transparency for doing green Sheng PPM environment-friendly materials is high, and color and luster is affected
Little.
Calcium carbonate itself is not hygroscopic, without constitution water and the crystallization water, but in the collection of usual ore, storage, processing and storehouse
During storage, because powder granule is minimum, moisture is easily absorbed.Requirement of the plastics in use to moisture is high, powder standard
≤ 0.5%, during practical application is required, powder water content answers≤0.3%, and the less impact to plastic products of water content is less.This
Heat in equipment heating and friction during the bright activation modification by us, effectively excludes the moisture carried in powder, activation
Later there is the surface protection of lipophilic group again so that powder is difficult moisture is absorbed, while also back segment banburying and extruding pelletization
Process heats abundant cladding while excluding moisture further with vector resin, reduces the directly contact with moisture in air,
So that the moisture of product is controlled in 0.2% level below, impact will not be produced on plastic products.
The present invention provides PPM environment-friendly materials, and under temperature, pressure collective effect, dispersant, lubricant, coupling agent etc. are helped
Agent is fully reacted, and the resin carrier under allowing powder granule and elastomeric state is uniformly mixed in the presence of being incorporated in Van der Waals force and makes activation powder
The lipophilic group of the body surface face other end adsorbs on the side chain of resin carrier, due to stretching and inflation to resin macromolecular it
Between, bring space between resin macromolecular and the fibrous rigid structure of inorganic particle itself, effectively reduce the density of product.Survey
Test result shows that the HDPE density of film for adding 30% PPM environment-friendly materials is 0.958%, and horizontal and vertical tensile strength is respectively
26.04MPa and 28.64MPa, contrasts conventional HDPE films, and combination property is dramatically increased；The similar interpolation inserts in contrast market
Product, than increasing by 32% and 62% respectively, density reduces 8% to tensile property.In the partially thin industry of this profit of plastic processing, density
Reduction by cause product competitiveness greatly improve.
