Embodiment 1

[0016] A straw oil-absorbing agent, which is made by mixing the following components: moss peat 22kg, Javan kapok fiber 35kg, polyamide fiber 20kg, acetic anhydride acylated straw 35kg. Each kilogram of oil absorbent obtained by mixing can absorb about 44.2 kilograms of oil.

[0017] 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.

Embodiment 2

[0019] A straw oil-absorbing agent, which is made by mixing the following components: moss peat 26kg, Java kapok fiber 30kg, polyamide fiber 25kg, acetic anhydride acylated straw 30kg. Each kilogram of oil absorbent obtained by mixing can absorb about 42.4 kilograms of oil.

Embodiment 3

[0021] A straw oil-absorbing agent, made by mixing the following components: moss peat 25kg, Java kapok fiber 32kg, polyamide fiber 22kg, acetic anhydride acylated straw 32kg. Each kilogram of oil absorbent obtained by mixing can absorb about 40.5 kilograms of oil.

Abstract

The invention relates to the technical field of a new adsorption material, and particularly relates to a straw oil absorbent. The straw oil absorbent is mainly prepared by mixing the following components in parts by weight: 22-26 parts of moss peat, 30-35 parts of kapok fiber, 20-25 parts of nylon and 30-35 parts of acetic anhydride acylation straw. The oil absorbent can be used after being mixed, and also can be used after being formed into a certain shape by a binder. The acetic anhydride acylation straw, namely a crop straw is prepared in a manner of directly reacting with acetic anhydride at a high temperature of 120-130 DEG C. The moss peat is good in oil absorption effect and good in hygroscopic property, so that the moss peat cannot be suitable for use on water or soil. The single acetic anhydride acylation straw is poor in floatability when being used as the oil absorbent. Therefore, proper four materials are selected to effectively compound by a lot of long-term research; the prepared oil absorbent has a good oil absorption effect, is wide in applicability and good in floatability, and can be used on water or soil.

Description

technical field [0001] The invention relates to the technical field of new adsorption materials, in particular to a straw oil absorbent. 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 02114713.2 p...
