Description
Technical field
The present invention relates to composite filled particles of a kind of chinampa and preparation method thereof, belong to chinampa field filler
Technical field.
Background technology
As emerging sport industry, chinampa has fidelity height, good weatherability, round-the-clock use, environmental protection and energy saving etc.
Performance has been widely used in the places such as football, hockey, croquet.But current common chinampa is functionally still
So have some limitations and drawback：Elasticity and noise cushion performance are poor：There is the phenomenon that hardened, grass in lawn after long-time service
There is the phenomenon that abrasion residual disconnected in level ground silk, entire lawn without elasticity, and cause green surface to the cushioning effect of noise very
It is faint；Environment resistant interference is poor：In cold winter, since light application time is especially short, while day and night temperature is bigger, so
The temperature on night place surface is especially low, is unfavorable for the movement of sportsman, simultaneously because the scenes material such as too low careless silk of temperature
Hardness, which becomes larger, moves the phenomenon that being easier to abrade when tumble, so safety is relatively low；And in the hot summer
Since the temperature of the common artificial green surface of the irradiation of sunlight is very high, 70-80 degrees Celsius is generally reached, sportsman in season
Activity when contacting to earth it is easy to appear burning the phenomenon that, so safety is relatively low.
Invention content
For overcome the deficiencies in the prior art, of the invention first to be designed to provide a kind of chinampa composite filled
Particle, the filler particles have the characteristics that good, wear-resistant elasticity, heat preservation, buffering for being laid with the athletic grounds such as chinampa.
Second object of the present invention is to provide a kind of preparation method of the composite filled particle of above-mentioned chinampa.
Realizing first purpose of the present invention can be reached by adopting the following technical scheme that：A kind of chinampa is compound to be filled out
Particle is filled, the clad including centrophyten and fitting cladding centrophyten；The centrophyten is equipped with buffering suface；In described
The grain size of heart particle is 0.1-3mm；The clad is rubber adhesive；The thickness of the clad is 0.3-1mm.
Further, the cladding layer segment cladding centrophyten.
Further, the centrophyten includes at least four plane buffering sufaces；At least four planes buffering suface closes
It surrounds around the surface for forming centrophyten；Junction between the plane buffering suface forms collision apex angle.
Further, the buffering suface of the centrophyten is cambered surface buffering suface.
Further, the centrophyten is granulated cork or coconut husk particle.
Cork is commonly called as yew, cork, cork, is the crust product of very flourishing seeds, after stem and root diameter increment
Surface protection tissue.
Further, the clad is EPDM (ethylene propylene diene rubber) or SBR (butadiene-styrene rubber) clad.
Realize that second object of the present invention can reach by adopting the following technical scheme that：It is a kind of as described above artificial
The preparation method of the composite filled particle in lawn, including：
The preparation process of centrophyten：Raw material is taken to be sieved after cutting, obtains the centrophyten that grain size is 0.1-3mm；
Coat the preparation process of slurry：Rubber with auxiliary agent is mixed and is heated under conditions of 110-250 DEG C, is coated
Slurry；
Encapsulation steps：Cladding slurry is attached to the surface of centrophyten, composite filled of chinampa is obtained after cooling
Grain.
Further, the centrophyten is equipped with cambered surface buffering suface, in the preparation process of centrophyten, after raw material is cut
Polishing, is then sieved.
Further, the encapsulation steps are：Centrophyten is added in roller, temperature is 110-200 DEG C, rotating speed is
Under conditions of 8-25rpm, cladding slurry is added in by roller with the speed of 5-20g/min, after cladding slurry addition, stops adding
Heat is simultaneously rotated further roller to temperature and is cooled to 40 DEG C hereinafter, obtaining the composite filled particle of chinampa.
Further, the gross mass of centrophyten and total mass ratio that adds in of cladding slurry are 2:(1-10).
Easily so that coating slurry attaches uneven, the bad control of thickness using the parameter of common process, it should be in rotating speed knot
Under the addition speed for closing cladding slurry, centrophyten is enabled to uniformly to attach cladding slurry, and to be formed the thickness of clad
It spends in 0.3-1mm, can realize that the clad of formation coats centrophyten completely.
The gross mass of centrophyten and total restriction for adding in quality of cladding slurry can prepare part cladding or complete
The composite filled particle of cladding, prepares the composite filled particle coated completely, and preferred ratio is 2:(5-10)；Part is prepared to wrap
The composite filled particle covered, preferred ratio are 2:(1-5).
Compared with prior art, the beneficial effects of the present invention are：
1st, the present invention improves cushion effect with centrophyten, but is easily raised due to the centrophyten lighter weight under the density
It rises or when wet water floats, therefore increase its weight by clad, the resiliency of composite filled particle entirety can either be promoted
It can, it may have the characteristics of stablizing filling maintains the overall structure of chinampa, improves the usage comfort of chinampa；
2nd, composite filled particle of the invention can play the role of temperature buffer, have the effect of heat preservation；
3rd, composite filled particle of the invention has the function of to absorb noise, reduces place echo.
Description of the drawings
Fig. 1 is the structure diagram of embodiment 1；
Fig. 2 is the structure diagram of embodiment 3；
In figure, 1, centrophyten；11st, plane buffering suface；12nd, apex angle is collided；13rd, cambered surface buffering suface；2nd, clad.

It is constant, if it can therefore be concluded that under the temperature of high fever, can also keeps the temperature more relatively low than weather.
2nd, for the research of the preparation method technological parameter of the composite filled particle of chinampa：
The raw material of particle centered on cork, buffering suface are arc buffering face, that is, the shape for setting centrophyten is circle
Shape or ellipse set different parameters, detect the ratio that its composite filled particle coated completely accounts for all composite filled particles
Example is used as qualification rate.Design parameter is as shown in table 4：
The technological parameter setting of 4 test case 1~8 of table
It can be obtained from table 4, wherein the qualification rate highest of test case 1 and test case 2, combination of process parameters are optimal.Although it wherein surveys
The grain size of example 3 is bigger than test case 1,2, but the usage ratio for coating slurry is smaller than test case 1,2, illustrates under technical arrangement plan,
The dosage that cladding slurry can be reduced still has preferable qualification rate.Test case 5-6 sets higher rotating speed and cladding slurry adds
Enter speed, and coat that usage of sizing agent is less, and effect is poorer than test case 1-3.And test case 7-8 setting speeds are higher but cladding slurry adds
It is slower to enter speed, qualification rate is minimum, from test case 5-8 it is known that each parameter effect with synergy, grain size, temperature,
Rotating speed, addition speed and dosage are both needed to the qualification rate that could be improved and coat completely of working in coordination.
For those skilled in the art, technical solution that can be as described above and design are made other each
Kind is corresponding to be changed and deforms, and all these change and deform the protection model that should all belong to the claims in the present invention
Within enclosing.
