JPS60179138A - Adsorbent of oil or the like - Google Patents

Abstract

PURPOSE:To cause gelation of oil or the like in the inside of a mat and to adsorb much oil or the like in the mat and to prevent the oil from flowing out to the outside even if external force is applied thereto by mixing a solid-state oil gelation agent or with an absorbent made of fiber in a melt-sticking state with each fiber. CONSTITUTION:A solid-state oil gelation agent 2 having component such as amino acid derivatives, sorbitol derivatives and perlite is mixed with an absorbent 1 made of fiber in a melt-sticking state with each fiber. The absorbent A of oil or the like is compact and useful extremely as treatment material for wiping off oil dirt and for adsorbing the remaining oil and flowed-out oil, etc. Since the oil component adsorbed to a mat is caused to gelation by the action of the gelation agent and structured with the fiber in one body in an interlocking state, its treatment becomes easy in each case of disposal and incineration. Also, the oil gelation agent is melt-stuck on the fiber to fix and stabilize, and bonded in one body without separating from the absorbent. The adsorbent is package easily and also no obstacles are generated even if it is wound in a roll-shape or folded with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adsorbent for oil and the like, and more particularly to an adsorbent devised to adsorb and gelatinize oil and the like so that it can be easily processed.

When frying food with oil, the oil oxidizes after it is used several times and becomes unusable, so it must be discarded, but the reality is that each household is worried about how to dispose of this waste oil. Specifically, you can soak it up with newspaper or rags and throw it away, put it in a bottle or paper liquid container, or even just pour it into the sink. There was no.

Recently, a waste oil-absorbing pine tree 1- which makes post-treatment easier has finally been developed and is now commercially available.

This waste oil absorbing mat is composed of mostly natural fibers and a small amount of synthetic fibers, and care is taken to keep the apparent honeycomb size low and bulky when forming the mat. In other words, this waste oil-absorbing pine i~ forms a low-density, bulky pine 1~ with oil-absorbing natural fibers, and the fibers themselves absorb oil and the spaces between the fibers created by the low-density structure are filled with oil. It has a structure that efficiently absorbs oil by adsorbing it.

However, such waste oil absorbing pine 1~ has the following drawbacks.

■ If oil is absorbed to a saturated state, 1 (η
When pressure is applied from the outside through the action of picking or picking, does it hold in the pine mill? 111 flows out from the pine tree 1.

■ Difficult to downsize due to bulkiness.
As a result, packaging costs and shipping costs are relatively high.

The present invention solves the above problems all at once, and instead of making the absorbent body bulky, an oil gelling agent is mixed in the absorbent body.
This is a scale that gels oil, etc. inside the mat, and allows the mat to adsorb a large amount of oil, etc., and even if pressure is applied from the outside, the oil, etc. that has been adsorbed inside the absorbent body will not leak out to the outside. , rather than retaining oil etc. in the spaces between the fibers,
It is characterized by having the function of gelling oil, etc. by the action of an oil gelling agent mixed in the absorbent body, forming an integral structure with the fibers in the form of a route, and holding it inside the pine 1.

More specifically, the solid oil gelling agents used in the present invention include amino acid derivatives, sorbitol derivatives,
Solid materials such as powders, granules, flakes, and fibers that contain pearlite-based components and absorb oil to form a gel are used.

The adsorbent according to the present invention is made by mixing a solid oil gelling agent with each fiber in a fused form in a fiber absorber to make it compact.
: In addition to the oil adsorption and retention function, the oil gelling agent itself is constructed to satisfy the fixing properties of the oil gelling agent itself in the absorbent body.

The fiber absorbent material can be in various shapes suitable for its use, such as mat, sheet, rod, rope, and other shapes without limitations in thickness and size. Fibers or natural fibers such as cotton, chemical fibers such as rayon or acetate, heat-fusible single fibers, and/or
Alternatively, various types of synthetic fibers such as composite fibers may be used, and each fiber may be used alone or in any combination depending on the purpose and shape. Note that synthetic fibers include both hydrophilic/oleophilic fibers and hydrophobic/oleophobic fibers.

As a result, the present invention has the following advantages.

Since the solid oil gelling agent is mixed with each fiber in the fiber absorber in a fused manner, it is compact and extremely useful as a material for wiping off oil stains and adsorbing residual oil and spilled oil. Due to the action of the gelling agent, the oil component adsorbed on the mat gels and connects with the fibers.4? Because it is an i-structured material, it is easy to dispose of it or incinerate it.

b. The oil gelling agent is fused to the fibers and is stable, so the gelling agent does not separate from the absorbent body and is integrated, making it easy to wrap or roll. Or,
There is no problem even when folded, and it is also useful for long dolls such as A-il fences used in tanker accidents. effective.

Furthermore, it goes without saying that the present invention can be used in a wide range of applications, from household waste oil treatment to industrial use, by appropriately changing the blending ratio of the gelling agent mixed in the absorbent body.

Examples of the present invention will be described below.

The adsorbent (A>) in the drawing is formed of a fiber absorber (1) and a solid oil gluing agent (2) fused thereon in an amount of 1 ffl.
