Abstract
The invention relates to a dangerous chemical adsorbent based on a polymer gel material and an application method thereof and belongs to the technical field of processing of high polymer material. The polymer gel adsorbent is composed of 10-300 parts of polymer gel materials, 400-900 parts of neutralizers, 1-10 parts of color reagents and 10-100 parts of anti-caking agent. When acid-base liquid waste leaks, the polymer gel adsorbent is scattered on the periphery and surface of the acid-base liquid waste, so that the function of preventing proliferation is achieved, and then the state of neutralizing and absorbing progress is quickly judged according to the color indication of PH color reagent contained by the polymer gel adsorbent, and the residue solid achieving neutral PH and formed by absorbing is collected and duly handled. Compared with the singly used inorganic mineral absorbing material, the polymer gel adsorbent material adopted for mixing with the neutralizer in appropriate proportion according to the invention has the advantages that the water absorbing efficiency of the polymer gel adsorbent is greatly increased, the adsorbent dosage is reduced, the corrosivity of the chemicals also can be reduced due to the usage of the neutralizer and the risk of onsite rescuer is relieved.
Description
Technical field
The present invention relates to a kind of hazardous chemical adsorbent based on Macromolecule glue material and preparation method thereof, belong to processing of high molecular material technical field.
Background technology
Hazardous chemical refers to have murder by poisoning, burn into blast, burning, the character such as combustion-supporting, has severe poisonous chemicals and other chemicals of harm to human body, facility, environment.
Hazardous Chemical Substances leakage can bring harm greatly to environment and lives and properties.Particularly severe corrosive soda acid, because it is in industrial undertaking, the extensive application in scientific experiment place, its leakage is the most frequent, and the major accident that strong acid and highly basic leakage cause happens occasionally.
Disposal for Hazardous Chemical Substances leakage, article one, basic principle is exactly to be processed into nontoxic, harmless as far as possible by hypertoxic, poisonous, harmful hazardous chemical or toxicity is relatively low, harm is less material, avoid causing secondary pollution, reduce and reduce as far as possible the loss of the harm that dangerous chemical leakage accident is caused.Can be disposed by the multiple method such as (as reclaimed, collect, adsorbing) of physics, chemical (as neutralized reaction, redox reaction, precipitation).
The risk revealed for Hazardous Chemical Substances, people have invented some adsorbing materials also for property, promptly speedily carrying out rescue work in time revealing generation.These adsorbing materials, based on inorganic mineral material, such as silicon dioxide, bentonite, meerschaum etc., utilize the absorption characteristic that these inorganic material have itself, absorb liquid and be immobilized in inside adsorbing material, to reach to control the purpose of leakage diffusion further.
But within the water absorption of these inorganic mineral materials only accounts for several times of this body weight, there is the shortcoming that water-taking efficiency is low, cause onsite application amount high, add fixed-end forces workload and processing cost.
This shortcoming of inorganic mineral material significantly limit its application when processing strong acid or highly basic leakage.But on the other hand, organic adsorption material such as high-molecular gel, because it cannot fully extend at strong acid or strong alkali environment Middle molecule chain, lose the function of absorption, be also difficult to play a role when processing strong acid or highly basic leakage.
Thus, how to select efficient adsorbing material and be applied to the environment of strong acid and highly basic and cause the great interest of research worker.
Chinese invention " residual active sludge prepares the method for chemical leakage accident adsorbent ", application number 201510670123.0 discloses a kind of method using residual active sludge to prepare chemicals adsorbent；Chinese invention " oily sludge prepares the method for chemical leakage accident adsorbent ", application number 201510370433.2 discloses a kind of method using oily sludge to prepare chemicals adsorbent, Macromolecule glue material is used for hazardous chemical adsorbent and have not been reported.
Summary of the invention
It is an object of the invention to provide a kind of based on Macromolecule glue material, it is aided with Hazardous Chemical Substances adsorbent and the preparation method of neutralization materials and colour reagent, this Hazardous Chemical Substances adsorbent still can be with active adsorption chemical leakage in the environment of strong acid and highly basic, consumption is less than inorganic mineral adsorbing material simultaneously, and reaches the on-the-spot purpose efficiently controlling chemical hazard.
For realizing the purpose of foregoing invention, the technical scheme that the present invention takes is as follows:
