Embodiment 1

[0021] Embodiment 1 isophorone diisocyanate and polyetheramine dosage ratio optimization

[0022] The configuration of IPDI macromolecular gel decontamination agent takes 25g of isopropanol, the total mass of isophorone diisocyanate and polyetheramine D230 is 75g, and the dosage ratio of isophorone diisocyanate and polyetheramine D230 is set to a gradient of 4 : 1, 3: 1, 2: 1, 1: 1, 1: 2, 1: 3, 1: 4; Prepare 500g of toluene to be decontaminated, and put it in a container with a surface area of ​​0.2 square meters, and set up 7 containers in total.

[0023] Mix polyetheramine D230 and isopropanol evenly and sprinkle it evenly on the surface of the container, then sprinkle isophorone diisocyanate evenly on the surface of the container, start timing, when the mixture in the container appears as figure 1 When the gel state is shown, stop timing and calculate the time (s) for gel formation.

[0024] Measurement results such as figure 2 As shown, when the mass ratio of isophorone...

Embodiment 2

[0025] Example 2 Optimization of the total mass ratio of isopropanol to isophorone diisocyanate and polyetheramine D230

[0026] Isopropanol is used as a dispersant, the amount of addition will affect the viscosity, mechanical properties and encapsulation rate of the final gel, and will eventually affect the volatilization of toluene in the gel.

[0027] The configuration of IPDI macromolecule gel decontamination agent, the total amount is 100g, the dosage ratio of isophorone diisocyanate and polyether amine is 1:1, the total amount of isopropanol, isophorone diisocyanate and polyether amine D230 The mass ratio of the mass, set the gradient to 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8; prepare 1000g of toluene to be decontaminated, and place it on the surface area In a container of 0.2 square meters, a total of 8 containers are set.

[0028] Mix polyetheramine D230 and isopropanol evenly and sprinkle it on the surface of the container, and then sprinkle isophorone diisocyanate e...

Embodiment 3

[0032] The optimum amount optimization of embodiment 3 gel decontamination agent

[0033] For the configuration of IPDI macromolecular gel decontamination agent, take 25g of isopropanol, 37.5g of isophorone diisocyanate, 37.5g of polyetheramine D230, and dissolve polyetheramine D230 in isopropanol; prepare respectively toluene to be decontaminated 2500g (equivalent to 4% of the mass of toluene used as a decontaminant), 2000g (5%), 1600g (6.25%), 1000g (10%), 666g (15%), 500g (20%), 400g (25%) ), 300g (33%) are placed in a container with a surface area of ​​0.2 square meters, and 8 containers are arranged in total.

[0034] Mix polyetheramine D230 and isopropanol evenly and sprinkle it on the surface of the container, and then sprinkle isophorone diisocyanate evenly on the surface of the container. When the mixture in the container appears as figure 1 When the gel state is shown, the gel is formed.

[0035] After the gel was formed, the detection method as in Example 2 was us...

Abstract

The invention discloses an IPDI macromolecular gel decontaminating agent. The decontaminating agent is prepared from the following components in parts by weight: 35-40 parts of isophorone diisocyanate, 35-40 parts of polyether amine D230 and 20-30 parts of isopropanol. Polyether amine D230 and isophorone diisocyanate are subjected to a chemical reaction, a macromolecular substance generated through the reaction is a gel, a gel skeleton can be generated through the chemical bond effect to wrap methylbenzene, and the generated gel is a non-toxic and pollution-free micromolecular substance and becomes a white solid after being dried. The product disclosed by the invention is high in reaction speed, and a curing effect can be achieved within 2 minutes; the dosage of the decontaminating agent is small, the decontaminating agent can be cured when the content of the decontaminating agent is about 4%, and various parameters of a decontaminating product are optimal when the content is 15%; andthe decontamination product is convenient for subsequent treatment and can be quickly recycled.

Description

technical field [0001] The invention belongs to the technical field of post-disposal treatment of dangerous chemical goods, and in particular relates to an IPDI macromolecular gel decontaminant. Background technique [0002] With the rapid development of my country's modern industry, toluene is an important chemical raw material, and leakage accidents occur frequently due to various reasons. Toluene has the characteristics of flowing and volatilizing rapidly, burning and exploding when exposed to heat or open flame, and having a great poisonous effect on the surrounding environment and human body. The characteristic is that once such hazardous chemicals leak, if the situation cannot be controlled in a short time to curb the development, it will cause pollution of the surrounding soil and water bodies at the slightest, and cause casualties or even cause serious consequences such as fire and explosion. In dealing with such leakage accidents of hazardous chemicals, the emergency...
