Fig. 1 (a) is the stereogram of one for schematically showing the rice huller paddy roller of the present invention, and (b) is the rice huller paddy roller shown in (a)
Front view, (c) is the line A-A profile of (a).
Rice huller paddy roller 10 shown in Fig. 1 (a)~(c) includes metal core portion 11 and is laminated in the outer peripheral face in core portion 11
Rubber layer 12.
Core portion 11 is the cylinder that the mounting flange 11a for paddy roller 10 of hulling to be installed on to hulling machine is provided with cylinder
Shape component.
Core portion 11 whole outer peripheral face with uniform thickness formed with rubber layer 12.
Hereinafter, the member of formation of the rice huller paddy roller of the present invention is illustrated.
As the core portion, person identical with the core portion used in existing known rice huller paddy roller can be used.Described
Core portion is as material, such as can enumerate:Aluminium, stainless steel, iron, molybdenum, titanium etc..
In addition, the shape or size in the core portion are not particularly limited, and it is same with existing product, rice huller is installed as long as coordinating
The specification of the hulling machine of paddy roller or Japanese Industrial Standards (Japanese industrial standard, JIS) standard (JIS B
9214:Rice huller paddy rubber rollers) suitably setting.
The rubber layer includes the thermosetting amino containing polyol component, isocyanate prepolymer composition, crosslinking agent and silicone oil
The hardening thing of urethane composition, the kinematic viscosity at 25 DEG C of the silicone oil is 10mm2/ s~3000mm2/s。
In the rice huller paddy roller of the present invention, by the silicon for containing the scope in the thermosetting carbamate composition
Oil, it can especially lift the durability (abrasion performance) of rubber layer.
In contrast, the kinematic viscosity at 25 DEG C of the silicone oil is less than 10mm2/ s situation or the kinematic viscosity
More than 3000mm2In the case of/s, the durability of rubber layer significantly reduces.
And then rice huller paddy roller of the invention as be described hereinafter as, by containing silicone oil in thermosetting carbamate composition,
And realize the lifting of water resistance.Herein, silicone oil the kinematic viscosity less than 10mm2In the case of/s, although can ensure that rubber
The water resistance at glue-line initial stage, but that the water resistance after rubber layer abrasion becomes insufficient be present.In addition described in silicone oil
Kinematic viscosity is less than 10mm2In the case of/s, produce silicone oil sometimes oozes out (bleed), if producing oozing out for silicone oil,
Brown rice can be polluted during rice huller paddy or rice husk is attached on hulling machine.
In addition, if the kinematic viscosity of silicone oil is more than 3000mm2/ s, then it is difficult to handle, and is preparing thermosetting ammonia
During carbamate composition, it is difficult to equably mix silicone oil.Included on possessing not by the mixed uniformly thermosetting of silicone oil
The rice huller paddy roller of the rubber layer of the hardening thing of carbamate composition, produced sometimes in the durability reduction of rice huller paddy roller or rubber layer
Husking yield when raw uneven abrasion or rice huller paddy reduces.
The rice huller paddy roller of the present invention reaches rubber layer by the way that silicone oil is formulated in thermosetting carbamate composition
Durability lifting.Now, it is important that not only allocate silicone oil, but allocate the silicon with the special exercise viscosity
Oil.In this way, it is by the newfound opinion of the present inventor et al.:, can outstandingly by allocating the silicone oil with special exercise viscosity
Lift the durability of rubber layer.
In the thermosetting carbamate composition, relative to polyol component, isocyanate prepolymer composition and crosslinking
The total amount of agent, the content of the silicone oil are the weight % of 0.3 weight %~10.0.
If the content of the silicone oil can not assign sufficient water resistance less than 0.3 weight % to rubber layer.In addition, such as
Upper described, rice huller paddy roller of the invention containing silicone oil in thermosetting carbamate composition by realizing the resistance to of rubber layer
The lifting of long property, if but silicone oil content less than 0.3 weight %, can not fully lift durability.
On the other hand, if the content of the silicone oil is more than 10 weight %, although durability and water resistance are good, can produce
Raw silicone oil oozes out.If producing oozing out for silicone oil, there is the unfavorable condition.
Relative to the total amount of polyol component, isocyanate prepolymer composition and crosslinking agent, content preferably 0.5 weight of the silicone oil
Measure the weight % of %~5.0 weight %, more preferably 0.7 weight %~2.5.
It is considered following reason by allocating the reasons why silicone oil is lifted and water resistance:Situation phase with not allocating silicone oil
Than, the hydrophobicity enhancing on the surface of rubber layer, therefore rubber layer is not easy moisture absorption, so as to be not likely to produce the water because of polyurethanes
Deterioration caused by solution.
On the rice huller paddy roller, building rubber compound is formed using the thermosetting carbamate composition containing silicone oil
Thing, and be scattered here and there silicone oil in whole rubber layer.So even the rubber layer abrasion by using rice huller paddy roller, the surface of rubber layer
Hydrophobicity can also be ensured all the time by silicone oil, after manufacture, can maintain excellent water resistance until being finished rice huller paddy roller.
Therefore, rice huller paddy roller of the invention is installed on after hulling machine, even if hulling machine interrupts operating for a long time, can also be avoided
The rubber layer deteriorates during interruption and the performance for paddy roller of hulling reduces.
It is not particularly limited, such as can enumerates as the silicone oil:Dimethicone, methyl phenyl silicone oil, methyl hydrogen silicon

Among these, preferred dimethicone.Dimethicone structure in silicone oil is more simple, does not have in space big
Steric hindrance (steric hindrance), therefore when being scattered in carbamate composition, it is easily dispersed in polyurethanes
In molecule, and suitable for making the hardening thing of thermosetting carbamate composition become uniform.On the other hand, on such as modified silicon oil
As have be likely to become steric hindrance position silicone oil, following situation be present:In the entangled to each other of polyurethane ester molecule
Middle silicone oil causes silicone oil to locally lie in the hardening thing of thermosetting carbamate composition without importing.Such as sometimes
