Abstract
The invention relates to an application of a rubber foaming body and a rice hull activated carbon as rubber foaming additives. The waste of the rice hull is converted into the activated carbon by high-temperature combustion (more than 600 DEG C); the activated carbon and natural rubber or artificial rubber are mixed and foamed into activated carbon sponge; as the activated carbon of the rice hull has the characteristics of short fiber, porosity and light weight (low specific gravity), the sponge body has air permeability, odor absorption, low specific gravity and high elasticity, thus being capable of being widely applied to good base materials which has high requirement on the air permeability, such as inner soles, chair cushions and the like needed in daily life, also being capable of replacing or reducing the proportion of petrochemical materials of petrochemical foaming materials so as to reduce the waste of petroleum energy, and perfecting the problems of environment protection.
Description
Technical field
The present invention relates to a kind of rice hull active carbon as the application of rubber foaming additive and a kind of, utilize its distinctive rerum natura and a kind of ventilation property height, water-absorbent is good, deodorization is strong environmentfriendly products are provided with the foamed rubber of rice husk as the gac material.
Background technology
The high development of nearly petrochemical industry in half a century for human life brings many conveniences, not only has its indispensable status really in the utilization of the energy, and truly has its high value added to exist on daily necessities.Only with present general employed foam sponge, still in the majority mostly with the petrochemical industry material, for example: the sponge that ethene-vinyl acetate ester (Ethylence-Vinylacetate is called for short EVA), thermoplastic elastomer (Thermoplastic rubber is called for short TPR), urethane (Poly-urethane is called for short PU) or synthetic chloroprene rubber foaming form, its shortcoming is ventilation property difference and not environmental protection.Though natural rubber is also for one of adopting, yet, cause foam can't breathe freely and the more high shortcoming of proportion, cause use range narrow and be difficult to popularization because of limit by the rubber pange technology.
Well-known paddy is after spreading shells, and rice becomes our main food, and rice husk but becomes irritating waste, and general peasant is sprinkled upon the fooled fertilizer of farmland with it after fuel uses or piles up burning.Never the someone finds that rice husk has peculiar rerum naturas such as fiber is short, pore is many and in addition utilization of waste material, really belongs to unfortunately.This case contriver is how thinking gives regeneration with the rice husk waste, and is comburant (-rent) with the rice husk waste, and then the rice husk breeze regeneration after will burning.Promptly carry out full scale test and test subsequently, find that effect is better more than expection.Satisfy with method arrangement proposition patent application of the present invention, in the hope of agricultural, industry, petrochemical industry industry and environment-friendly engineering are had far-reaching benefiting.
Summary of the invention
At the deficiencies in the prior art, the objective of the invention is to: the application as rubber foaming additive of a kind of foamed rubber and rice hull active carbon is provided, can overcomes the existing airtight and hyperbaric problem of current foamed rubber (as Fig. 3, shown in Figure 5) fully.
For achieving the above object, the technical solution used in the present invention comprises:
A kind of foamed rubber is characterized in that, it is made with following method: at first be that material becomes rice hull active carbon through high-temp combustion with the rice husk, get an amount of rice hull active carbon and compounding rubber, give foaming then.
Wherein: described rubber is natural rubber or synthetic chloroprene rubber.
Wherein: described high temperature is 600 ℃～800 ℃.
For achieving the above object, the technical solution used in the present invention also comprises:
A kind of rice hull active carbon is as the application of rubber foaming additive.
Wherein: at first be that material forms described rice hull active carbon through high-temp combustion with the rice husk, with compounding rubber, giving foaming then is foamed rubber behind the described rice hull active carbon.
Wherein: described rubber is natural rubber or synthetic chloroprene rubber.
Wherein: described high temperature is 600 ℃～800 ℃.
Compared with prior art, the beneficial effect that has of the present invention is: relatively cleaner because of the gac made with rice husk, fiber is short, pore is many and evenly, light specific gravity, easily miniaturization and easily and compounding rubber even.Foaming thing surface pattern is careful, though epidermal area is arranged because of the gas port of gac be that globality distributes (if observe without magnifying glass, naked eyes can't be seen), thereby the good characteristic of comprehensive ventilation property, water-absorbent and deodorization is arranged, real is a quantum jump of industrial technology.

Fig. 3: natural rubber does not add the air hole structure figure after the paddy gac foaming of the present invention;
Fig. 4: the air hole structure figure after synthetic chloroprene rubber (petrochemical industry material) and the mixing foaming of paddy gac of the present invention;
Fig. 5: synthetic chloroprene rubber (petrochemical industry material) does not add the air hole structure figure after the paddy gac foaming of the present invention.
Embodiment
As shown in Figure 1, at first the paddy skin being peeled off the rice husk that gets off puts in stove, bestowing high temperature (is the best with 600 ℃～800 ℃) burning makes its charing become gac, it is mixing to get an amount of rice hull active carbon and natural rubber or synthetic chloroprene rubber then, its objective is make rice hull active carbon more miniaturization and with natural rubber or synthetic chloroprene rubber uniform mixing.Then give foaming to prolong compressing tablet open foam-in-mould or the outer foaming mode of the mould after the die sinking continuous foamed or compression molding.
Wherein: the mixing part by weight between rice hull active carbon and the rubber preferably: rice hull active carbon accounts for 60%～70%, and rubber accounts for 30%～40%.
Behind rice hull active carbon and natural rubber or synthetic chloroprene rubber mixed foaming, each walls of foam is built bridge because of the media that gac is arranged and is linked to each other, and make the stephanoporate intercommunication of each hole wall, fine hole wall has the porous characteristic, the well ventilative physical structure (as Fig. 2, shown in Figure 4) that links to each other of real frame, and have high-tensile strength, a good and splendid adsorptivity of elasticity, for other petrochemical industry material foaies can't be obtained.
In today of stressing environmental protection, the rice husk waste of decapacitation digestion farm crop of the present invention, and the foaming thing that is used and is converted into high additive value and function are if then can reduce the usage quantity of petrochemical industry material as the additive of petrochemical industry material; As omnidistance if with 100% natural foamed substrate, then can reach environmental protection purpose completely: if be that foamed substrate then can reduce the shared ratio of petrochemical material with synthetic chloroprene rubber, outside the waste that reduces petroleum-based energy, more can obtain the ultimate aim of environmental protection, can be rated as and serve multiple.
More than explanation is just illustrative for the purpose of the present invention, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present invention.
