Embodiment Construction

[0020] As shown in Figure 1, first put the rice husk peeled off from the outer layer of rice in the furnace, apply high temperature (600°C to 800°C is the best) and burn it to carbonize it into activated carbon, then take an appropriate amount of rice husk activated carbon and The purpose of natural rubber or artificial rubber mixing is to make rice husk activated carbon finer and evenly mixed with natural rubber or artificial rubber. Then, foam molding is performed by open continuous foaming of the rolled sheet or in-mold foaming of compression molding or out-of-mold foaming after mold opening.

[0021] Wherein: the mixing weight ratio between rice husk activated carbon and rubber is preferably: rice husk activated carbon accounts for 60%-70%, and rubber accounts for 30%-40%.

[0022] When rice husk activated carbon is mixed with natural rubber or artificial rubber and foamed, each cell wall of the foam is bridged and connected by the medium of activated carbon, so that each ...

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 [0001] The invention relates to the application of rice husk activated carbon as a rubber foaming additive and a rubber foam using rice husk as an activated carbon material, which provides a high air permeability, good water absorption and deodorizing rubber foam by utilizing its unique physical properties. Strong environmental protection products. Background technique [0002] The high development of the petrochemical industry in the past half century has indeed brought a lot of convenience to human life, not only has its indispensable position in the utilization of energy, but also has its extremely high added value in the necessities of life . As far as the foam sponges currently used are concerned, most of them are still made of petrochemical materials, such as: ethylene-vinylacetate (EVA), thermoplastic rubber (Thermoplastic rubber, TPR), polyurethane (Poly-urethane) PU) or artificial rubber foamed sponge, its disadvantages are poor air permeability an...
