Embodiment 1

[0019] A straw oil-absorbing product, which is composed of moss peat, Java kapok fiber, polyamide fiber, and acetic anhydride acylated straw, respectively, in a layered structure. The preparation method of acetic anhydride acylated straw is as follows: put the crop straw in the reactor, add acetic anhydride, the amount of acetic anhydride added is preferably to immerse the straw, react at a high temperature of 120-130°C for 2 hours, and then filter to obtain acetic anhydride Acylated straw, set aside.

[0020] The straw oil-absorbing product of this embodiment forms a product with a layered structure, such as figure 1 As shown, the core layer of the straw oil-absorbing product is the moss peat layer 1, and the two sides of the moss peat layer are the Java kapok fiber layer 2, and the outer side of the Java kapok fiber layer is adjacent to the acetic anhydride acylated straw layer 3. The outermost layer is a polyamide fiber layer 4 . This special multi-layer sandwich structur...

Embodiment 2

[0022] A straw oil-absorbing product, which is composed of moss peat, Java kapok fiber, polyamide fiber, and acetic anhydride acylated straw, respectively, in a layered structure. The specific structure is the same as that of Example 2, the difference is that a 0.5-1cm sawdust layer 5 is added between the acetic anhydride acylated straw layer and the polyamide fiber layer, see figure 2 . In order to increase the adsorption effect, at this time, each kilogram of oil absorbent can absorb about 53.5 kilograms of oil.

Embodiment 3

[0024] A straw oil-absorbing product, which is composed of moss peat, Java kapok fiber, polyamide fiber, and acetic anhydride acylated straw, respectively, in a layered structure. The specific structure is the same as in Example 2, the difference being that the thickness ratios of the moss peat layer, Java kapok fiber layer, acetic anhydride acylated straw layer, and polyamide fiber layer are respectively 1 cm, 1.2 cm, 1.5 cm, and 1.1 cm. The straw oil-absorbing product is made into a round or square bag-like structure, and the edges are sewn around it, so that the moss peat layer, Java kapok fiber layer, and acetic anhydride acylated straw layer are located inside the outer polyamide fiber layer, forming Pocket structure. This structure is beneficial to recycle after oil absorption.

Abstract

The invention belongs to the field of novel adsorbing materials, and especially relates to a straw oil-absorbing product. The straw oil-absorbing product is prepared by recombination of layer structures which are respectively made of moss peat, ceiba pentandra fiber, polyarmide fiber and acetic anhydride acylated straw. The core layer of the straw oil-absorbing product is made of moss peat, the two surfaces of the moss peat layer are made of ceiba pentandra fiber, the acetic anhydride acylated straw layers are next to the outer surfaces of the ceiba pentandra fiber layers, and the outmost layers of the straw oil-absorbing product are the polyarmide fiber layers. The special multilayer sandwich structure is capable of increasing oil absorption effect, and realizing oil recovery by extruding after using, and the reuse of the straw oil-absorbing product.

Description

technical field [0001] The invention relates to the technical field of new adsorption materials, in particular to a straw oil absorption product. Background technique [0002] Various oil spill accidents are unavoidable in the process of oil exploration, mining, storage, transportation and use. Oil spills have caused serious damage to the natural environment, not only endangering public health, but also polluting water sources and aquatic animals and plants. There are currently two main methods for solving oil spills on land and in water, chemical methods and physical recovery methods. Chemical methods usually use dispersants and burn in situ to dispose of spilled oil. Dispersants are used to speed up the natural breakdown process of oil in water. The method of burning in situ is relatively simple, but it will produce a lot of chemical residues and thick smoke, which is not conducive to environmental protection. The Chinese invention patent with application number 021...
